If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## License - -MIT © [Sindre Sorhus](http://sindresorhus.com) diff --git a/node_modules/ansi-styles/index.d.ts b/node_modules/ansi-styles/index.d.ts deleted file mode 100644 index 7e9b2b7..0000000 --- a/node_modules/ansi-styles/index.d.ts +++ /dev/null @@ -1,197 +0,0 @@ -import * as cssColors from 'color-name'; - -declare namespace ansiStyles { - interface ColorConvert { - /** - The RGB color space. - - @param red - (`0`-`255`) - @param green - (`0`-`255`) - @param blue - (`0`-`255`) - */ - rgb(red: number, green: number, blue: number): string; - - /** - The RGB HEX color space. - - @param hex - A hexadecimal string containing RGB data. - */ - hex(hex: string): string; - - /** - @param keyword - A CSS color name. - */ - keyword(keyword: keyof typeof cssColors): string; - - /** - The HSL color space. - - @param hue - (`0`-`360`) - @param saturation - (`0`-`100`) - @param lightness - (`0`-`100`) - */ - hsl(hue: number, saturation: number, lightness: number): string; - - /** - The HSV color space. - - @param hue - (`0`-`360`) - @param saturation - (`0`-`100`) - @param value - (`0`-`100`) - */ - hsv(hue: number, saturation: number, value: number): string; - - /** - The HSV color space. - - @param hue - (`0`-`360`) - @param whiteness - (`0`-`100`) - @param blackness - (`0`-`100`) - */ - hwb(hue: number, whiteness: number, blackness: number): string; - - /** - Use a [4-bit unsigned number](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4-bit) to set text color. - */ - ansi(ansi: number): string; - - /** - Use an [8-bit unsigned number](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) to set text color. - */ - ansi256(ansi: number): string; - } - - interface CSPair { - /** - The ANSI terminal control sequence for starting this style. - */ - readonly open: string; - - /** - The ANSI terminal control sequence for ending this style. - */ - readonly close: string; - } - - interface ColorBase { - readonly ansi: ColorConvert; - readonly ansi256: ColorConvert; - readonly ansi16m: ColorConvert; - - /** - The ANSI terminal control sequence for ending this color. - */ - readonly close: string; - } - - interface Modifier { - /** - Resets the current color chain. - */ - readonly reset: CSPair; - - /** - Make text bold. - */ - readonly bold: CSPair; - - /** - Emitting only a small amount of light. - */ - readonly dim: CSPair; - - /** - Make text italic.

However, you should always use `img.onload` and `img.onerror`, as we intend to make `img.src=` always asynchronous as it is in browsers. See https://github.com/Automattic/node-canvas/issues/1007.* - -### Image#dataMode - -> ```ts -> img.dataMode: number -> ``` - -Applies to JPEG images drawn to PDF canvases only. - -Setting `img.dataMode = Image.MODE_MIME` or `Image.MODE_MIME|Image.MODE_IMAGE` enables MIME data tracking of images. When MIME data is tracked, PDF canvases can embed JPEGs directly into the output, rather than re-encoding into PNG. This can drastically reduce filesize and speed up rendering. - -```javascript -const { Image, createCanvas } = require('canvas') -const canvas = createCanvas(w, h, 'pdf') -const img = new Image() -img.dataMode = Image.MODE_IMAGE // Only image data tracked -img.dataMode = Image.MODE_MIME // Only mime data tracked -img.dataMode = Image.MODE_MIME | Image.MODE_IMAGE // Both are tracked -``` - -If working with a non-PDF canvas, image data *must* be tracked; otherwise the output will be junk. - -Enabling mime data tracking has no benefits (only a slow down) unless you are generating a PDF. - -### Canvas#toBuffer() - -> ```ts -> canvas.toBuffer((err: Error|null, result: Buffer) => void, mimeType?: string, config?: any) => void -> canvas.toBuffer(mimeType?: string, config?: any) => Buffer -> ``` - -Creates a [`Buffer`](https://nodejs.org/api/buffer.html) object representing the image contained in the canvas. - -* **callback** If provided, the buffer will be provided in the callback instead of being returned by the function. Invoked with an error as the first argument if encoding failed, or the resulting buffer as the second argument if it succeeded. Not supported for mimeType `raw` or for PDF or SVG canvases. -* **mimeType** A string indicating the image format. Valid options are `image/png`, `image/jpeg` (if node-canvas was built with JPEG support), `raw` (unencoded data in BGRA order on little-endian (most) systems, ARGB on big-endian systems; top-to-bottom), `application/pdf` (for PDF canvases) and `image/svg+xml` (for SVG canvases). Defaults to `image/png` for image canvases, or the corresponding type for PDF or SVG canvas. -* **config** - * For `image/jpeg`, an object specifying the quality (0 to 1), if progressive compression should be used and/or if chroma subsampling should be used: `{quality: 0.75, progressive: false, chromaSubsampling: true}`. All properties are optional. - - * For `image/png`, an object specifying the ZLIB compression level (between 0 and 9), the compression filter(s), the palette (indexed PNGs only), the the background palette index (indexed PNGs only) and/or the resolution (ppi): `{compressionLevel: 6, filters: canvas.PNG_ALL_FILTERS, palette: undefined, backgroundIndex: 0, resolution: undefined}`. All properties are optional. - - Note that the PNG format encodes the resolution in pixels per meter, so if you specify `96`, the file will encode 3780 ppm (~96.01 ppi). The resolution is undefined by default to match common browser behavior. - - * For `application/pdf`, an object specifying optional document metadata: `{title: string, author: string, subject: string, keywords: string, creator: string, creationDate: Date, modDate: Date}`. All properties are optional and default to `undefined`, except for `creationDate`, which defaults to the current date. *Adding metadata requires Cairo 1.16.0 or later.* - - For a description of these properties, see page 550 of [PDF 32000-1:2008](https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/PDF32000_2008.pdf). - - Note that there is no standard separator for `keywords`. A space is recommended because it is in common use by other applications, and Cairo will enclose the list of keywords in quotes if a comma or semicolon is used. - -**Return value** - -If no callback is provided, a [`Buffer`](https://nodejs.org/api/buffer.html). If a callback is provided, none. - -#### Examples - -```js -// Default: buf contains a PNG-encoded image -const buf = canvas.toBuffer() - -// PNG-encoded, zlib compression level 3 for faster compression but bigger files, no filtering -const buf2 = canvas.toBuffer('image/png', { compressionLevel: 3, filters: canvas.PNG_FILTER_NONE }) - -// JPEG-encoded, 50% quality -const buf3 = canvas.toBuffer('image/jpeg', { quality: 0.5 }) - -// Asynchronous PNG -canvas.toBuffer((err, buf) => { - if (err) throw err // encoding failed - // buf is PNG-encoded image -}) - -canvas.toBuffer((err, buf) => { - if (err) throw err // encoding failed - // buf is JPEG-encoded image at 95% quality -}, 'image/jpeg', { quality: 0.95 }) - -// BGRA pixel values, native-endian -const buf4 = canvas.toBuffer('raw') -const { stride, width } = canvas -// In memory, this is `canvas.height * canvas.stride` bytes long. -// The top row of pixels, in BGRA order on little-endian hardware, -// left-to-right, is: -const topPixelsBGRALeftToRight = buf4.slice(0, width * 4) -// And the third row is: -const row3 = buf4.slice(2 * stride, 2 * stride + width * 4) - -// SVG and PDF canvases -const myCanvas = createCanvas(w, h, 'pdf') -myCanvas.toBuffer() // returns a buffer containing a PDF-encoded canvas -// With optional metadata: -myCanvas.toBuffer('application/pdf', { - title: 'my picture', - keywords: 'node.js demo cairo', - creationDate: new Date() -}) -``` - -### Canvas#createPNGStream() - -> ```ts -> canvas.createPNGStream(config?: any) => ReadableStream -> ``` - -Creates a [`ReadableStream`](https://nodejs.org/api/stream.html#stream_class_stream_readable) that emits PNG-encoded data. - -* `config` An object specifying the ZLIB compression level (between 0 and 9), the compression filter(s), the palette (indexed PNGs only) and/or the background palette index (indexed PNGs only): `{compressionLevel: 6, filters: canvas.PNG_ALL_FILTERS, palette: undefined, backgroundIndex: 0, resolution: undefined}`. All properties are optional. - -#### Examples - -```javascript -const fs = require('fs') -const out = fs.createWriteStream(__dirname + '/test.png') -const stream = canvas.createPNGStream() -stream.pipe(out) -out.on('finish', () => console.log('The PNG file was created.')) -``` - -To encode indexed PNGs from canvases with `pixelFormat: 'A8'` or `'A1'`, provide an options object: - -```js -const palette = new Uint8ClampedArray([ - //r g b a - 0, 50, 50, 255, // index 1 - 10, 90, 90, 255, // index 2 - 127, 127, 255, 255 - // ... -]) -canvas.createPNGStream({ - palette: palette, - backgroundIndex: 0 // optional, defaults to 0 -}) -``` - -### Canvas#createJPEGStream() - -> ```ts -> canvas.createJPEGStream(config?: any) => ReadableStream -> ``` - -Creates a [`ReadableStream`](https://nodejs.org/api/stream.html#stream_class_stream_readable) that emits JPEG-encoded data. - -*Note: At the moment, `createJPEGStream()` is synchronous under the hood. That is, it runs in the main thread, not in the libuv threadpool.* - -* `config` an object specifying the quality (0 to 1), if progressive compression should be used and/or if chroma subsampling should be used: `{quality: 0.75, progressive: false, chromaSubsampling: true}`. All properties are optional. - -#### Examples - -```javascript -const fs = require('fs') -const out = fs.createWriteStream(__dirname + '/test.jpeg') -const stream = canvas.createJPEGStream() -stream.pipe(out) -out.on('finish', () => console.log('The JPEG file was created.')) - -// Disable 2x2 chromaSubsampling for deeper colors and use a higher quality -const stream = canvas.createJPEGStream({ - quality: 0.95, - chromaSubsampling: false -}) -``` - -### Canvas#createPDFStream() - -> ```ts -> canvas.createPDFStream(config?: any) => ReadableStream -> ``` - -* `config` an object specifying optional document metadata: `{title: string, author: string, subject: string, keywords: string, creator: string, creationDate: Date, modDate: Date}`. See `toBuffer()` for more information. *Adding metadata requires Cairo 1.16.0 or later.* - -Applies to PDF canvases only. Creates a [`ReadableStream`](https://nodejs.org/api/stream.html#stream_class_stream_readable) that emits the encoded PDF. `canvas.toBuffer()` also produces an encoded PDF, but `createPDFStream()` can be used to reduce memory usage. - -### Canvas#toDataURL() - -This is a standard API, but several non-standard calls are supported. The full list of supported calls is: - -```js -dataUrl = canvas.toDataURL() // defaults to PNG -dataUrl = canvas.toDataURL('image/png') -dataUrl = canvas.toDataURL('image/jpeg') -dataUrl = canvas.toDataURL('image/jpeg', quality) // quality from 0 to 1 -canvas.toDataURL((err, png) => { }) // defaults to PNG -canvas.toDataURL('image/png', (err, png) => { }) -canvas.toDataURL('image/jpeg', (err, jpeg) => { }) // sync JPEG is not supported -canvas.toDataURL('image/jpeg', {...opts}, (err, jpeg) => { }) // see Canvas#createJPEGStream for valid options -canvas.toDataURL('image/jpeg', quality, (err, jpeg) => { }) // spec-following; quality from 0 to 1 -``` - -### CanvasRenderingContext2D#patternQuality - -> ```ts -> context.patternQuality: 'fast'|'good'|'best'|'nearest'|'bilinear' -> ``` - -Defaults to `'good'`. Affects pattern (gradient, image, etc.) rendering quality. - -### CanvasRenderingContext2D#quality - -> ```ts -> context.quality: 'fast'|'good'|'best'|'nearest'|'bilinear' -> ``` - -Defaults to `'good'`. Like `patternQuality`, but applies to transformations affecting more than just patterns. - -### CanvasRenderingContext2D#textDrawingMode - -> ```ts -> context.textDrawingMode: 'path'|'glyph' -> ``` - -Defaults to `'path'`. The effect depends on the canvas type: - -* **Standard (image)** `glyph` and `path` both result in rasterized text. Glyph mode is faster than `path`, but may result in lower-quality text, especially when rotated or translated. - -* **PDF** `glyph` will embed text instead of paths into the PDF. This is faster to encode, faster to open with PDF viewers, yields a smaller file size and makes the text selectable. The subset of the font needed to render the glyphs will be embedded in the PDF. This is usually the mode you want to use with PDF canvases. - -* **SVG** `glyph` does *not* cause `` elements to be produced as one might expect ([cairo bug](https://gitlab.freedesktop.org/cairo/cairo/issues/253)). Rather, `glyph` will create a `` section with a `` for each glyph, then those glyphs be reused via `` elements. `path` mode creates a `` element for each text string. `glyph` mode is faster and yields a smaller file size. - -In `glyph` mode, `ctx.strokeText()` and `ctx.fillText()` behave the same (aside from using the stroke and fill style, respectively). - -This property is tracked as part of the canvas state in save/restore. - -### CanvasRenderingContext2D#globalCompositeOperation = 'saturate' - -In addition to all of the standard global composite operations defined by the Canvas specification, the ['saturate'](https://www.cairographics.org/operators/#saturate) operation is also available. - -### CanvasRenderingContext2D#antialias - -> ```ts -> context.antialias: 'default'|'none'|'gray'|'subpixel' -> ``` - -Sets the anti-aliasing mode. - -## PDF Output Support - -node-canvas can create PDF documents instead of images. The canvas type must be set when creating the canvas as follows: - -```js -const canvas = createCanvas(200, 500, 'pdf') -``` - -An additional method `.addPage()` is then available to create multiple page PDFs: - -```js -// On first page -ctx.font = '22px Helvetica' -ctx.fillText('Hello World', 50, 80) - -ctx.addPage() -// Now on second page -ctx.font = '22px Helvetica' -ctx.fillText('Hello World 2', 50, 80) - -canvas.toBuffer() // returns a PDF file -canvas.createPDFStream() // returns a ReadableStream that emits a PDF -// With optional document metadata (requires Cairo 1.16.0): -canvas.toBuffer('application/pdf', { - title: 'my picture', - keywords: 'node.js demo cairo', - creationDate: new Date() -}) -``` - -It is also possible to create pages with different sizes by passing `width` and `height` to the `.addPage()` method: - -```js -ctx.font = '22px Helvetica' -ctx.fillText('Hello World', 50, 80) -ctx.addPage(400, 800) - -ctx.fillText('Hello World 2', 50, 80) -``` - -See also: - -* [Image#dataMode](#imagedatamode) for embedding JPEGs in PDFs -* [Canvas#createPDFStream()](#canvascreatepdfstream) for creating PDF streams -* [CanvasRenderingContext2D#textDrawingMode](#canvasrenderingcontext2dtextdrawingmode) - for embedding text instead of paths - -## SVG Output Support - -node-canvas can create SVG documents instead of images. The canvas type must be set when creating the canvas as follows: - -```js -const canvas = createCanvas(200, 500, 'svg') -// Use the normal primitives. -fs.writeFileSync('out.svg', canvas.toBuffer()) -``` - -## SVG Image Support - -If librsvg is available when node-canvas is installed, node-canvas can render SVG images to your canvas context. This currently works by rasterizing the SVG image (i.e. drawing an SVG image to an SVG canvas will not preserve the SVG data). - -```js -const img = new Image() -img.onload = () => ctx.drawImage(img, 0, 0) -img.onerror = err => { throw err } -img.src = './example.svg' -``` - -## Image pixel formats (experimental) - -node-canvas has experimental support for additional pixel formats, roughly following the [Canvas color space proposal](https://github.com/WICG/canvas-color-space/blob/master/CanvasColorSpaceProposal.md). - -```js -const canvas = createCanvas(200, 200) -const ctx = canvas.getContext('2d', { pixelFormat: 'A8' }) -``` - -By default, canvases are created in the `RGBA32` format, which corresponds to the native HTML Canvas behavior. Each pixel is 32 bits. The JavaScript APIs that involve pixel data (`getImageData`, `putImageData`) store the colors in the order {red, green, blue, alpha} without alpha pre-multiplication. (The C++ API stores the colors in the order {alpha, red, green, blue} in native-[endian](https://en.wikipedia.org/wiki/Endianness) ordering, with alpha pre-multiplication.) - -These additional pixel formats have experimental support: - -* `RGB24` Like `RGBA32`, but the 8 alpha bits are always opaque. This format is always used if the `alpha` context attribute is set to false (i.e. `canvas.getContext('2d', {alpha: false})`). This format can be faster than `RGBA32` because transparency does not need to be calculated. -* `A8` Each pixel is 8 bits. This format can either be used for creating grayscale images (treating each byte as an alpha value), or for creating indexed PNGs (treating each byte as a palette index) (see [the example using alpha values with `fillStyle`](examples/indexed-png-alpha.js) and [the example using `imageData`](examples/indexed-png-image-data.js)). -* `RGB16_565` Each pixel is 16 bits, with red in the upper 5 bits, green in the middle 6 bits, and blue in the lower 5 bits, in native platform endianness. Some hardware devices and frame buffers use this format. Note that PNG does not support this format; when creating a PNG, the image will be converted to 24-bit RGB. This format is thus suboptimal for generating PNGs. `ImageData` instances for this mode use a `Uint16Array` instead of a `Uint8ClampedArray`. -* `A1` Each pixel is 1 bit, and pixels are packed together into 32-bit quantities. The ordering of the bits matches the endianness of the - platform: on a little-endian machine, the first pixel is the least-significant bit. This format can be used for creating single-color images. *Support for this format is incomplete, see note below.* -* `RGB30` Each pixel is 30 bits, with red in the upper 10, green in the middle 10, and blue in the lower 10. (Requires Cairo 1.12 or later.) *Support for this format is incomplete, see note below.* - -Notes and caveats: - -* Using a non-default format can affect the behavior of APIs that involve pixel data: - - * `context2d.createImageData` The size of the array returned depends on the number of bit per pixel for the underlying image data format, per the above descriptions. - * `context2d.getImageData` The format of the array returned depends on the underlying image mode, per the above descriptions. Be aware of platform endianness, which can be determined using node.js's [`os.endianness()`](https://nodejs.org/api/os.html#os_os_endianness) - function. - * `context2d.putImageData` As above. - -* `A1` and `RGB30` do not yet support `getImageData` or `putImageData`. Have a use case and/or opinion on working with these formats? Open an issue and let us know! (See #935.) - -* `A1`, `A8`, `RGB30` and `RGB16_565` with shadow blurs may crash or not render properly. - -* The `ImageData(width, height)` and `ImageData(Uint8ClampedArray, width)` constructors assume 4 bytes per pixel. To create an `ImageData` instance with a different number of bytes per pixel, use `new ImageData(new Uint8ClampedArray(size), width, height)` or `new ImageData(new Uint16ClampedArray(size), width, height)`. - -## Testing - -First make sure you've built the latest version. Get all the deps you need (see [compiling](#compiling) above), and run: - -``` -npm install --build-from-source -``` - -For visual tests: `npm run test-server` and point your browser to http://localhost:4000. - -For unit tests: `npm run test`. - -## Benchmarks - -Benchmarks live in the `benchmarks` directory. - -## Examples - -Examples line in the `examples` directory. Most produce a png image of the same name, and others such as *live-clock.js* launch an HTTP server to be viewed in the browser. - -## Original Authors - - - TJ Holowaychuk ([tj](http://github.com/tj)) - - Nathan Rajlich ([TooTallNate](http://github.com/TooTallNate)) - - Rod Vagg ([rvagg](http://github.com/rvagg)) - - Juriy Zaytsev ([kangax](http://github.com/kangax)) - -## License - -### node-canvas - -(The MIT License) - -Copyright (c) 2010 LearnBoost, and contributors <dev@learnboost.com> - -Copyright (c) 2014 Automattic, Inc and contributors <dev@automattic.com> - -Permission is hereby granted, free of charge, to any person obtaining a copy of -this software and associated documentation files (the 'Software'), to deal in -the Software without restriction, including without limitation the rights to -use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of -the Software, and to permit persons to whom the Software is furnished to do so, -subject to the following conditions: - -The above copyright notice and this permission notice shall be included in all -copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS -FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## Maintainers - -- [Sindre Sorhus](https://github.com/sindresorhus) -- [Josh Junon](https://github.com/qix-) - - ---- - -

To get the unrounded (raw) results, simply tack on `.raw` to the function. - -All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha). - -```js -var convert = require('color-convert'); - -// Hex to LAB -convert.hex.lab('DEADBF'); // [ 76, 21, -2 ] -convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ] - -// RGB to CMYK -convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ] -convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ] -``` - -### Arrays -All functions that accept multiple arguments also support passing an array. - -Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.) - -```js -var convert = require('color-convert'); - -convert.rgb.hex(123, 45, 67); // '7B2D43' -convert.rgb.hex([123, 45, 67]); // '7B2D43' -``` - -## Routing - -Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex). - -Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js). - -# Contribute - -If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request. - -# License -Copyright © 2011-2016, Heather Arthur and Josh Junon.

The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .option('-p, --peppers', 'Add peppers') - .option('-P, --pineapple', 'Add pineapple') - .option('-b, --bbq-sauce', 'Add bbq sauce') - .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble') - .parse(process.argv); - -console.log('you ordered a pizza with:'); -if (program.peppers) console.log(' - peppers'); -if (program.pineapple) console.log(' - pineapple'); -if (program.bbqSauce) console.log(' - bbq'); -console.log(' - %s cheese', program.cheese); -``` - -Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. - -Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .option('--no-sauce', 'Remove sauce') - .parse(process.argv); - -console.log('you ordered a pizza'); -if (program.sauce) console.log(' with sauce'); -else console.log(' without sauce'); -``` - -To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs. - -e.g. ```.option('-m --myarg [myVar]', 'my super cool description')``` - -Then to access the input if it was passed in. - -e.g. ```var myInput = program.myarg``` - -**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in. - - -## Version option - -Calling the `version` implicitly adds the `-V` and `--version` options to the command. -When either of these options is present, the command prints the version number and exits. - - $ ./examples/pizza -V - 0.0.1 - -If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method. - -```js -program - .version('0.0.1', '-v, --version') -``` - -The version flags can be named anything, but the long option is required. - -## Command-specific options - -You can attach options to a command. - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .command('rm ') - .option('-r, --recursive', 'Remove recursively') - .action(function (dir, cmd) { - console.log('remove ' + dir + (cmd.recursive ?

However, if an action-based command does not define an action, then the options are not validated. - -## Coercion - -```js -function range(val) { - return val.split('..').map(Number); -} - -function list(val) { - return val.split(','); -} - -function collect(val, memo) { - memo.push(val); - return memo; -} - -function increaseVerbosity(v, total) { - return total + 1; -} - -program - .version('0.1.0') - .usage('[options] ') - .option('-i, --integer ', 'An integer argument', parseInt) - .option('-f, --float ', 'A float argument', parseFloat) - .option('-r, --range ..', 'A range', range) - .option('-l, --list ', 'A list', list) - .option('-o, --optional [value]', 'An optional value') - .option('-c, --collect [value]', 'A repeatable value', collect, []) - .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0) - .parse(process.argv); - -console.log(' int: %j', program.integer); -console.log(' float: %j', program.float); -console.log(' optional: %j', program.optional); -program.range = program.range || []; -console.log(' range: %j..%j', program.range[0], program.range[1]); -console.log(' list: %j', program.list); -console.log(' collect: %j', program.collect); -console.log(' verbosity: %j', program.verbose); -console.log(' args: %j', program.args); -``` - -## Regular Expression -```js -program - .version('0.1.0') - .option('-s --size ', 'Pizza size', /^(large|medium|small)$/i, 'medium') - .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i) - .parse(process.argv); - -console.log(' size: %j', program.size); -console.log(' drink: %j', program.drink); -``` - -## Variadic arguments - - The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to - append `...` to the argument name. Here is an example: - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .command('rmdir [otherDirs...]') - .action(function (dir, otherDirs) { - console.log('rmdir %s', dir); - if (otherDirs) { - otherDirs.forEach(function (oDir) { - console.log('rmdir %s', oDir); - }); - } - }); - -program.parse(process.argv); -``` - - An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed - to your action as demonstrated above. - -## Specify the argument syntax - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .version('0.1.0') - .arguments(' [env]') - .action(function (cmd, env) { - cmdValue = cmd; - envValue = env; - }); - -program.parse(process.argv); - -if (typeof cmdValue === 'undefined') { - console.error('no command given!'); - process.exit(1); -} -console.log('command:', cmdValue); -console.log('environment:', envValue || "no environment given"); -``` -Angled brackets (e.g. ``) indicate required input. Square brackets (e.g. `[env]`) indicate optional input. - -## Git-style sub-commands - -```js -// file: ./examples/pm -var program = require('commander'); - -program - .version('0.1.0') - .command('install [name]', 'install one or more packages') - .command('search [query]', 'search with optional query') - .command('list', 'list packages installed', {isDefault: true}) - .parse(process.argv); -``` - -When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools. -The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`. - -Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified. - -If the program is designed to be installed globally, make sure the executables have proper modes, like `755`. - -### `--harmony` - -You can enable `--harmony` option in two ways: -* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern. -* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process. - -## Automated --help - - The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free: - -``` -$ ./examples/pizza --help -Usage: pizza [options] - -An application for pizzas ordering - -Options: - -h, --help output usage information - -V, --version output the version number - -p, --peppers Add peppers - -P, --pineapple Add pineapple - -b, --bbq Add bbq sauce - -c, --cheese Add the specified type of cheese [marble] - -C, --no-cheese You do not want any cheese -``` - -## Custom help - - You can display arbitrary `-h, --help` information - by listening for "--help". Commander will automatically - exit once you are done so that the remainder of your program - does not execute causing undesired behaviors, for example - in the following executable "stuff" will not output when - `--help` is used. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .option('-f, --foo', 'enable some foo') - .option('-b, --bar', 'enable some bar') - .option('-B, --baz', 'enable some baz'); - -// must be before .parse() since -// node's emit() is immediate - -program.on('--help', function(){ - console.log('') - console.log('Examples:'); - console.log(' $ custom-help --help'); - console.log(' $ custom-help -h'); -}); - -program.parse(process.argv); - -console.log('stuff'); -``` - -Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run: - -``` -Usage: custom-help [options] - -Options: - -h, --help output usage information - -V, --version output the version number - -f, --foo enable some foo - -b, --bar enable some bar - -B, --baz enable some baz - -Examples: - $ custom-help --help - $ custom-help -h -``` - -## .outputHelp(cb) - -Output help information without exiting. -Optional callback cb allows post-processing of help text before it is displayed. - -If you want to display help by default (e.g. if no command was provided), you can use something like: - -```js -var program = require('commander'); -var colors = require('colors'); - -program - .version('0.1.0') - .command('getstream [url]', 'get stream URL') - .parse(process.argv); - -if (!process.argv.slice(2).length) { - program.outputHelp(make_red); -} - -function make_red(txt) { - return colors.red(txt); //display the help text in red on the console -} -``` - -## .help(cb) - - Output help information and exit immediately. - Optional callback cb allows post-processing of help text before it is displayed. - - -## Custom event listeners - You can execute custom actions by listening to command and option events. - -```js -program.on('option:verbose', function () { - process.env.VERBOSE = this.verbose;

The first *bin*.x0 is always equal to the minimum domain value, and the last *bin*.x1 is always equal to the maximum domain value. - -If a *count* is specified instead of an array of *thresholds*, then the [domain](#bin_domain) will be uniformly divided into approximately *count* bins; see [ticks](#ticks). - -#### Bin Thresholds - -These functions are typically not used directly; instead, pass them to [*bin*.thresholds](#bin_thresholds). You may also implement your own threshold generator taking three arguments: the array of input [*values*](#bin_value) derived from the data, and the [observable domain](#bin_domain) represented as *min* and *max*. The generator may then return either the array of numeric thresholds or the *count* of bins; in the latter case the domain is divided uniformly into approximately *count* bins; see [ticks](#ticks). - -# d3.thresholdFreedmanDiaconis(values, min, max) · [Source](https://github.com/d3/d3-array/blob/master/src/threshold/freedmanDiaconis.js), [Examples](https://observablehq.com/@d3/d3-bin) - -Returns the number of bins according to the [Freedman–Diaconis rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdScott(values, min, max) · [Source](https://github.com/d3/d3-array/blob/master/src/threshold/scott.js), [Examples](https://observablehq.com/@d3/d3-bin) - -Returns the number of bins according to [Scott’s normal reference rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdSturges(values) · [Source](https://github.com/d3/d3-array/blob/master/src/threshold/sturges.js), [Examples](https://observablehq.com/@d3/d3-bin) - -Returns the number of bins according to [Sturges’ formula](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. diff --git a/node_modules/d3-array/dist/d3-array.js b/node_modules/d3-array/dist/d3-array.js deleted file mode 100644 index 182e87a..0000000 --- a/node_modules/d3-array/dist/d3-array.js +++ /dev/null @@ -1,796 +0,0 @@ -// https://d3js.org/d3-array/ v2.4.0 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(global = global || self, factory(global.d3 = global.d3 || {})); -}(this, function (exports) { 'use strict'; - -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} - -function bisector(compare) { - if (compare.length === 1) compare = ascendingComparator(compare); - return { - left: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) < 0) lo = mid + 1; - else hi = mid; - } - return lo; - }, - right: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) > 0) hi = mid; - else lo = mid + 1; - } - return lo; - } - }; -} - -function ascendingComparator(f) { - return function(d, x) { - return ascending(f(d), x); - }; -} - -var ascendingBisect = bisector(ascending); -var bisectRight = ascendingBisect.right; -var bisectLeft = ascendingBisect.left; - -function count(values, valueof) { - let count = 0; - if (valueof === undefined) { - for (let value of values) { - if (value != null && (value = +value) >= value) { - ++count; - } - } - } else { - let index = -1; - for (let value of values) { - if ((value = valueof(value, ++index, values)) != null && (value = +value) >= value) { - ++count; - } - } - } - return count; -} - -function length(array) { - return array.length | 0; -} - -function empty(length) { - return !(length > 0); -} - -function arrayify(values) { - return typeof values !== "object" || "length" in values ? values : Array.from(values); -} - -function reducer(reduce) { - return values => reduce(...values); -} - -function cross(...values) { - const reduce = typeof values[values.length - 1] === "function" && reducer(values.pop()); - values = values.map(arrayify); - const lengths = values.map(length); - const j = values.length - 1; - const index = new Array(j + 1).fill(0); - const product = []; - if (j < 0 || lengths.some(empty)) return product; - while (true) { - product.push(index.map((j, i) => values[i][j])); - let i = j; - while (++index[i] === lengths[i]) { - if (i === 0) return reduce ? product.map(reduce) : product; - index[i--] = 0; - } - } -} - -function cumsum(values, valueof) { - var sum = 0, index = 0; - return Float64Array.from(values, valueof === undefined - ? v => (sum += +v || 0) - : v => (sum += +valueof(v, index++, values) || 0)); -} - -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} - -function variance(values, valueof) { - let count = 0; - let delta; - let mean = 0; - let sum = 0; - if (valueof === undefined) { - for (let value of values) { - if (value != null && (value = +value) >= value) { - delta = value - mean; - mean += delta / ++count; - sum += delta * (value - mean); - } - } - } else { - let index = -1; - for (let value of values) { - if ((value = valueof(value, ++index, values)) != null && (value = +value) >= value) { - delta = value - mean; - mean += delta / ++count; - sum += delta * (value - mean); - } - } - } - if (count > 1) return sum / (count - 1); -} - -function deviation(values, valueof) { - const v = variance(values, valueof); - return v ?

If the specifier was not valid, null is returned. Some examples: - -* `rgb(255, 255, 255)` -* `rgb(10%, 20%, 30%)` -* `rgba(255, 255, 255, 0.4)` -* `rgba(10%, 20%, 30%, 0.4)` -* `hsl(120, 50%, 20%)` -* `hsla(120, 50%, 20%, 0.4)` -* `#ffeeaa` -* `#fea` -* `#ffeeaa22` -* `#fea2` -* `steelblue` - -The list of supported [named colors](http://www.w3.org/TR/SVG/types.html#ColorKeywords) is specified by CSS. - -Note: this function may also be used with `instanceof` to test if an object is a color instance.

Georgy “The Voronator” Voronoy - -This is a fast, no-dependency library for computing the [Voronoi diagram](https://en.wikipedia.org/wiki/Voronoi_diagram) of a set of two-dimensional points. It is based on [Delaunator](https://github.com/mapbox/delaunator), a fast library for computing the [Delaunay triangulation](https://en.wikipedia.org/wiki/Delaunay_triangulation) using [sweep algorithms](https://github.com/mapbox/delaunator/blob/master/README.md#papers). The Voronoi diagram is constructed by connecting the circumcenters of adjacent triangles in the Delaunay triangulation. - -For an interactive explanation of how this library works, see [The Delaunay’s Dual](https://observablehq.com/@mbostock/the-delaunays-dual). - -## Installing - -To install, `npm install d3-delaunay` or `yarn add d3-delaunay`. You can also download the [latest release](https://github.com/d3/d3-delaunay/releases/latest) or load directly from [unpkg](https://unpkg.com/d3-delaunay/). AMD, CommonJS and ES6+ environments are supported. In vanilla, a `d3` global is exported. - -```js -import {Delaunay} from "d3-delaunay"; - -const points = [[0, 0], [0, 1], [1, 0], [1, 1]]; -const delaunay = Delaunay.from(points); -const voronoi = delaunay.voronoi([0, 0, 960, 500]); -``` - -## API Reference - -### Delaunay - -# new Delaunay(points) [<>](https://github.com/d3/d3-delaunay/blob/master/src/delaunay.js "Source") - -Returns the Delaunay triangulation for the given flat array [*x0*, *y0*, *x1*, *y1*, …] of *points*. - -```js -const delaunay = new Delaunay(Float64Array.of(0, 0, 0, 1, 1, 0, 1, 1)); -``` - -# Delaunay.from(points[, fx[, fy[, that]]]) [<>](https://github.com/d3/d3-delaunay/blob/master/src/delaunay.js "Source") - -Returns the Delaunay triangulation for the given array or iterable of *points*. If *fx* and *fy* are not specified, then *points* is assumed to be an array of two-element arrays of numbers: [[*x0*, *y0*], [*x1*, *y1*], …]. Otherwise, *fx* and *fy* are functions that are invoked for each element in the *points* array in order, and must return the respective *x*- and *y*-coordinate for each point. If *that* is specified, the functions *fx* and *fy* are invoked with *that* as *this*. (See [Array.from](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array/from) for reference.) - -```js -const delaunay = Delaunay.from([[0, 0], [0, 1], [1, 0], [1, 1]]); -``` - -# delaunay.points - -The coordinates of the points as an array [*x0*, *y0*, *x1*, *y1*, …]. Typically, this is a Float64Array, however you can use any array-like type in the [constructor](#new_Delaunay). - -# delaunay.halfedges - -The halfedge indexes as an Int32Array [*j0*, *j1*, …]. For each index 0 ≤ *i* < *halfedges*.length, there is a halfedge from triangle vertex *j* = *halfedges*[*i*] to triangle vertex *i*. Equivalently, this means that triangle ⌊*i* / 3⌋ is adjacent to triangle ⌊*j* / 3⌋. If *j* is negative, then triangle ⌊*i* / 3⌋ is an exterior triangle on the [convex hull](#delaunay_hull). For example, to render the internal edges of the Delaunay triangulation: - -```js -const {points, halfedges, triangles} = delaunay; -for (let i = 0, n = halfedges.length; i < n; ++i) { - const j = halfedges[i]; - if (j < i) continue; - const ti = triangles[i]; - const tj = triangles[j]; - context.moveTo(points[ti * 2], points[ti * 2 + 1]); - context.lineTo(points[tj * 2], points[tj * 2 + 1]); -} -``` - -See also [*delaunay*.render](#delaunay_render). - -# delaunay.hull - -An Int32Array of point indexes that form the convex hull in counterclockwise order. If the points are collinear, returns them ordered. - -See also [*delaunay*.renderHull](#delaunay_renderHull). - -# delaunay.triangles - -The triangle vertex indexes as an Uint32Array [*i0*, *j0*, *k0*, *i1*, *j1*, *k1*, …]. Each contiguous triplet of indexes *i*, *j*, *k* forms a counterclockwise triangle. The coordinates of the triangle’s points can be found by going through [*delaunay*.points](#delaunay_points). For example, to render triangle *i*: - -```js -const {points, triangles} = delaunay; -const t0 = triangles[i * 3 + 0]; -const t1 = triangles[i * 3 + 1]; -const t2 = triangles[i * 3 + 2]; -context.moveTo(points[t0 * 2], points[t0 * 2 + 1]); -context.lineTo(points[t1 * 2], points[t1 * 2 + 1]); -context.lineTo(points[t2 * 2], points[t2 * 2 + 1]); -context.closePath(); -``` - -See also [*delaunay*.renderTriangle](#delaunay_renderTriangle). - -# delaunay.inedges - -The incoming halfedge indexes as a Int32Array [*e0*, *e1*, *e2*, …]. For each point *i*, *inedges*[*i*] is the halfedge index *e* of an incoming halfedge. For coincident points, the halfedge index is -1; for points on the convex hull, the incoming halfedge is on the convex hull; for other points, the choice of incoming halfedge is arbitrary. The *inedges* table can be used to traverse the Delaunay triangulation; see also [*delaunay*.neighbors](#delaunay_neighbors). - -# delaunay.find(x, y[, i]) [<>](https://github.com/d3/d3-delaunay/blob/master/src/delaunay.js "Source") - -Returns the index of the input point that is closest to the specified point ⟨*x*, *y*⟩.

A variety of D3 components, such as [d3-request](https://github.com/d3/d3-request), use this mechanism to emit events to listeners. Think of this like Node’s [EventEmitter](https://nodejs.org/api/events.html), except every listener has a well-defined name so it’s easy to remove or replace them. - -For example, to create a dispatch for *start* and *end* events: - -```js -var dispatch = d3.dispatch("start", "end"); -``` - -You can then register callbacks for these events using [*dispatch*.on](#dispatch_on): - -```js -dispatch.on("start", callback1); -dispatch.on("start.foo", callback2); -dispatch.on("end", callback3); -``` - -Then, you can invoke all the *start* callbacks using [*dispatch*.call](#dispatch_call) or [*dispatch*.apply](#dispatch_apply): - -```js -dispatch.call("start"); -``` - -Like *function*.call, you may also specify the `this` context and any arguments: - -```js -dispatch.call("start", {about: "I am a context object"}, "I am an argument"); -``` - -Want a more involved example?

If a *callback* function is specified, it is registered for the specified (fully-qualified) *typenames*. If a callback was already registered for the given *typenames*, the existing callback is removed before the new callback is added. - -The specified *typenames* is a string, such as `start` or `end.foo`. The type may be optionally followed by a period (`.`) and a name; the optional name allows multiple callbacks to be registered to receive events of the same type, such as `start.foo` and `start.bar`. To specify multiple typenames, separate typenames with spaces, such as `start end` or `start.foo start.bar`. - -To remove all callbacks for a given name `foo`, say `dispatch.on(".foo", null)`. - -If *callback* is not specified, returns the current callback for the specified *typenames*, if any. If multiple typenames are specified, the first matching callback is returned. - -# *dispatch*.copy() [<>](https://github.com/d3/d3-dispatch/blob/master/src/dispatch.js#L49 "Source") - -Returns a copy of this dispatch object.

For example, if you wanted to dispatch your *custom* callbacks after handling a native *click* event, while preserving the current `this` context and arguments, you could say: - -```js -selection.on("click", function() { - dispatch.apply("custom", this, arguments); -}); -``` - -You can pass whatever arguments you want to callbacks; most commonly, you might create an object that represents an event, or pass the current datum (*d*) and index (*i*).

This function is intended to be used as a *row* accessor function in conjunction with [*dsv*.parse](#dsv_parse) and [*dsv*.parseRows](#dsv_parseRow). For example, consider the following CSV file: - -``` -Year,Make,Model,Length -1997,Ford,E350,2.34 -2000,Mercury,Cougar,2.38 -``` - -When used with [d3.csvParse](#csvParse), - -```js -d3.csvParse(string, d3.autoType) -``` - -the resulting JavaScript array is: - -```js -[ - {"Year": 1997, "Make": "Ford", "Model": "E350", "Length": 2.34}, - {"Year": 2000, "Make": "Mercury", "Model": "Cougar", "Length": 2.38} -] -``` - -Type inference works as follows. For each *value* in the given *object*, the [trimmed](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/Trim) value is computed; the value is then re-assigned as follows: - -1. If empty, then `null`. -1. If exactly `"true"`, then `true`. -1. If exactly `"false"`, then `false`. -1. If exactly `"NaN"`, then `NaN`. -1. Otherwise, if [coercible to a number](https://www.ecma-international.org/ecma-262/9.0/index.html#sec-tonumber-applied-to-the-string-type), then a number. -1. Otherwise, if a [date-only or date-time string](https://www.ecma-international.org/ecma-262/9.0/index.html#sec-date-time-string-format), then a Date. -1. Otherwise, a string (the original untrimmed value). - -Values with leading zeroes may be coerced to numbers; for example `"08904"` coerces to `8904`. However, extra characters such as commas or units (*e.g.*, `"$1.00"`, `"(123)"`, `"1,234"` or `"32px"`) will prevent number coercion, resulting in a string. - -Date strings must be in ECMAScript’s subset of the [ISO 8601 format](https://en.wikipedia.org/wiki/ISO_8601). When a date-only string such as YYYY-MM-DD is specified, the inferred time is midnight UTC; however, if a date-time string such as YYYY-MM-DDTHH:MM is specified without a time zone, it is assumed to be local time. - -Automatic type inference is primarily intended to provide safe, predictable behavior in conjunction with [*dsv*.format](#dsv_format) and [*dsv*.formatRows](#dsv_formatRows) for common JavaScript types. If you need different behavior, you should implement your own row accessor function. - -For more, see [the d3.autoType notebook](https://observablehq.com/@d3/d3-autotype). - -### Content Security Policy - -If a [content security policy](http://www.w3.org/TR/CSP/) is in place, note that [*dsv*.parse](#dsv_parse) requires `unsafe-eval` in the `script-src` directive, due to the (safe) use of dynamic code generation for fast parsing. (See [source](https://github.com/d3/d3-dsv/blob/master/src/dsv.js).) Alternatively, use [*dsv*.parseRows](#dsv_parseRows). - -### Byte-Order Marks - -DSV files sometimes begin with a [byte order mark (BOM)](https://en.wikipedia.org/wiki/Byte_order_mark); saving a spreadsheet in CSV UTF-8 format from Microsoft Excel, for example, will include a BOM. On the web this is not usually a problem because the [UTF-8 decode algorithm](https://encoding.spec.whatwg.org/#utf-8-decode) specified in the Encoding standard removes the BOM. Node.js, on the other hand, [does not remove the BOM](https://github.com/nodejs/node-v0.x-archive/issues/1918) when decoding UTF-8. - -If the BOM is not removed, the first character of the text is a zero-width non-breaking space. So if a CSV file with a BOM is parsed by [d3.csvParse](#csvParse), the first column’s name will begin with a zero-width non-breaking space. This can be hard to spot since this character is usually invisible when printed. - -To remove the BOM before parsing, consider using [strip-bom](https://www.npmjs.com/package/strip-bom). - -## Command Line Reference - -### dsv2dsv - -# dsv2dsv [options…] [file] - -Converts the specified DSV input *file* to DSV (typically with a different delimiter or encoding). If *file* is not specified, defaults to reading from stdin.

If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added.

If *listener* is not specified, returns the first currently-assigned listener matching the specified *typenames*, if any. When a specified event is dispatched, each *listener* will be invoked with the `this` context as the simulation. - -The *typenames* is a string containing one or more *typename* separated by whitespace. Each *typename* is a *type*, optionally followed by a period (`.`) and a *name*, such as `tick.foo` and `tick.bar`; the name allows multiple listeners to be registered for the same *type*. The *type* must be one of the following: - -* `tick` - after each tick of the simulation’s internal timer. -* `end` - after the simulation’s timer stops when *alpha* < [*alphaMin*](#simulation_alphaMin). - -Note that *tick* events are not dispatched when [*simulation*.tick](#simulation_tick) is called manually; events are only dispatched by the internal timer and are intended for interactive rendering of the simulation. To affect the simulation, register [forces](#simulation_force) instead of modifying nodes’ positions or velocities inside a tick event listener. - -See [*dispatch*.on](https://github.com/d3/d3-dispatch#dispatch_on) for details. - -### Forces - -A *force* is simply a function that modifies nodes’ positions or velocities; in this context, a *force* can apply a classical physical force such as electrical charge or gravity, or it can resolve a geometric constraint, such as keeping nodes within a bounding box or keeping linked nodes a fixed distance apart. For example, a simple positioning force that moves nodes towards the origin ⟨0,0⟩ might be implemented as: - -```js -function force(alpha) { - for (var i = 0, n = nodes.length, node, k = alpha * 0.1; i < n; ++i) { - node = nodes[i]; - node.vx -= node.x * k; - node.vy -= node.y * k; - } -} -``` - -Forces typically read the node’s current position ⟨*x*,*y*⟩ and then add to (or subtract from) the node’s velocity ⟨*vx*,*vy*⟩. However, forces may also “peek ahead” to the anticipated next position of the node, ⟨*x* + *vx*,*y* + *vy*⟩; this is necessary for resolving geometric constraints through [iterative relaxation](https://en.wikipedia.org/wiki/Relaxation_\(iterative_method\)). Forces may also modify the position directly, which is sometimes useful to avoid adding energy to the simulation, such as when recentering the simulation in the viewport. - -Simulations typically compose multiple forces as desired. This module provides several for your enjoyment: - -* [Centering](#centering) -* [Collision](#collision) -* [Links](#links) -* [Many-Body](#many-body) -* [Positioning](#positioning) - -Forces may optionally implement [*force*.initialize](#force_initialize) to receive the simulation’s array of nodes. - -# force(alpha) [<>](https://github.com/d3/d3-force/blob/master/src/simulation.js#L47 "Source") - -Applies this force, optionally observing the specified *alpha*. Typically, the force is applied to the array of nodes previously passed to [*force*.initialize](#force_initialize), however, some forces may apply to a subset of nodes, or behave differently. For example, [d3.forceLink](#links) applies to the source and target of each link. - -# force.initialize(nodes) [<>](https://github.com/d3/d3-force/blob/master/src/simulation.js#L77 "Source") - -Assigns the array of *nodes* to this force. This method is called when a force is bound to a simulation via [*simulation*.force](#simulation_force) and when the simulation’s nodes change via [*simulation*.nodes](#simulation_nodes). A force may perform necessary work during initialization, such as evaluating per-node parameters, to avoid repeatedly performing work during each application of the force. - -#### Centering - -The centering force translates nodes uniformly so that the mean position of all nodes (the center of mass if all nodes have equal weight) is at the given position ⟨[*x*](#center_x),[*y*](#center_y)⟩. This force modifies the positions of nodes on each application; it does not modify velocities, as doing so would typically cause the nodes to overshoot and oscillate around the desired center. This force helps keeps nodes in the center of the viewport, and unlike the [positioning force](#positioning), it does not distort their relative positions. - -# d3.forceCenter([x, y]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L1 "Source") - -Creates a new centering force with the specified [*x*-](#center_x) and [*y*-](#center_y) coordinates. If *x* and *y* are not specified, they default to ⟨0,0⟩. - -# center.x([x]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L27 "Source") - -If *x* is specified, sets the *x*-coordinate of the centering position to the specified number and returns this force. If *x* is not specified, returns the current *x*-coordinate, which defaults to zero. - -# center.y([y]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L31 "Source") - -If *y* is specified, sets the *y*-coordinate of the centering position to the specified number and returns this force. If *y* is not specified, returns the current *y*-coordinate, which defaults to zero. - -#### Collision - -The collision force treats nodes as circles with a given [radius](#collide_radius), rather than points, and prevents nodes from overlapping. More formally, two nodes *a* and *b* are separated so that the distance between *a* and *b* is at least *radius*(*a*) + *radius*(*b*). To reduce jitter, this is by default a “soft” constraint with a configurable [strength](#collide_strength) and [iteration count](#collide_iterations). - -# d3.forceCollide([radius]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js "Source") - -Creates a new circle collision force with the specified [*radius*](#collide_radius). If *radius* is not specified, it defaults to the constant one for all nodes. - -# collide.radius([radius]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L86 "Source") - -If *radius* is specified, sets the radius accessor to the specified number or function, re-evaluates the radius accessor for each node, and returns this force. If *radius* is not specified, returns the current radius accessor, which defaults to: - -```js -function radius() { - return 1; -} -``` - -The radius accessor is invoked for each [node](#simulation_nodes) in the simulation, being passed the *node* and its zero-based *index*. The resulting number is then stored internally, such that the radius of each node is only recomputed when the force is initialized or when this method is called with a new *radius*, and not on every application of the force. - -# collide.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L82 "Source") - -If *strength* is specified, sets the force strength to the specified number in the range [0,1] and returns this force. If *strength* is not specified, returns the current strength which defaults to 0.7. - -Overlapping nodes are resolved through iterative relaxation. For each node, the other nodes that are anticipated to overlap at the next tick (using the anticipated positions ⟨*x* + *vx*,*y* + *vy*⟩) are determined; the node’s velocity is then modified to push the node out of each overlapping node. The change in velocity is dampened by the force’s strength such that the resolution of simultaneous overlaps can be blended together to find a stable solution. - -# collide.iterations([iterations]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L78 "Source") - -If *iterations* is specified, sets the number of iterations per application to the specified number and returns this force. If *iterations* is not specified, returns the current iteration count which defaults to 1. Increasing the number of iterations greatly increases the rigidity of the constraint and avoids partial overlap of nodes, but also increases the runtime cost to evaluate the force. - -#### Links - -The link force pushes linked nodes together or apart according to the desired [link distance](#link_distance). The strength of the force is proportional to the difference between the linked nodes’ distance and the target distance, similar to a spring force. - -# d3.forceLink([links]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js "Source") - -Creates a new link force with the specified *links* and default parameters. If *links* is not specified, it defaults to the empty array. - -# link.links([links]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L92 "Source") - -If *links* is specified, sets the array of links associated with this force, recomputes the [distance](#link_distance) and [strength](#link_strength) parameters for each link, and returns this force. If *links* is not specified, returns the current array of links, which defaults to the empty array. - -Each link is an object with the following properties: - -* `source` - the link’s source node; see [*simulation*.nodes](#simulation_nodes) -* `target` - the link’s target node; see [*simulation*.nodes](#simulation_nodes) -* `index` - the zero-based index into *links*, assigned by this method - -For convenience, a link’s source and target properties may be initialized using numeric or string identifiers rather than object references; see [*link*.id](#link_id). When the link force is [initialized](#force_initialize) (or re-initialized, as when the nodes or links change), any *link*.source or *link*.target property which is *not* an object is replaced by an object reference to the corresponding *node* with the given identifier. - -If the specified array of *links* is modified, such as when links are added to or removed from the simulation, this method must be called again with the new (or changed) array to notify the force of the change; the force does not make a defensive copy of the specified array. - -# link.id([id]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L96 "Source") - -If *id* is specified, sets the node id accessor to the specified function and returns this force. If *id* is not specified, returns the current node id accessor, which defaults to the numeric *node*.index: - -```js -function id(d) { - return d.index; -} -``` - -The default id accessor allows each link’s source and target to be specified as a zero-based index into the [nodes](#simulation_nodes) array. For example: - -```js -var nodes = [ - {"id": "Alice"}, - {"id": "Bob"}, - {"id": "Carol"} -]; - -var links = [ - {"source": 0, "target": 1}, // Alice → Bob - {"source": 1, "target": 2} // Bob → Carol -]; -``` - -Now consider a different id accessor that returns a string: - -```js -function id(d) { - return d.id; -} -``` - -With this accessor, you can use named sources and targets: - -```js -var nodes = [ - {"id": "Alice"}, - {"id": "Bob"}, - {"id": "Carol"} -]; - -var links = [ - {"source": "Alice", "target": "Bob"}, - {"source": "Bob", "target": "Carol"} -]; -``` - -This is particularly useful when representing graphs in JSON, as JSON does not allow references. See [this example](http://bl.ocks.org/mbostock/f584aa36df54c451c94a9d0798caed35). - -The id accessor is invoked for each node whenever the force is initialized, as when the [nodes](#simulation_nodes) or [links](#link_links) change, being passed the node and its zero-based index. - -# link.distance([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L108 "Source") - -If *distance* is specified, sets the distance accessor to the specified number or function, re-evaluates the distance accessor for each link, and returns this force. If *distance* is not specified, returns the current distance accessor, which defaults to: - -```js -function distance() { - return 30; -} -``` - -The distance accessor is invoked for each [link](#link_links), being passed the *link* and its zero-based *index*. The resulting number is then stored internally, such that the distance of each link is only recomputed when the force is initialized or when this method is called with a new *distance*, and not on every application of the force. - -# link.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L104 "Source") - -If *strength* is specified, sets the strength accessor to the specified number or function, re-evaluates the strength accessor for each link, and returns this force. If *strength* is not specified, returns the current strength accessor, which defaults to: - -```js -function strength(link) { - return 1 / Math.min(count(link.source), count(link.target)); -} -``` - -Where *count*(*node*) is a function that returns the number of links with the given node as a source or target. This default was chosen because it automatically reduces the strength of links connected to heavily-connected nodes, improving stability. - -The strength accessor is invoked for each [link](#link_links), being passed the *link* and its zero-based *index*. The resulting number is then stored internally, such that the strength of each link is only recomputed when the force is initialized or when this method is called with a new *strength*, and not on every application of the force. - -# link.iterations([iterations]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L100 "Source") - -If *iterations* is specified, sets the number of iterations per application to the specified number and returns this force. If *iterations* is not specified, returns the current iteration count which defaults to 1. Increasing the number of iterations greatly increases the rigidity of the constraint and is useful for [complex structures such as lattices](http://bl.ocks.org/mbostock/1b64ec067fcfc51e7471d944f51f1611), but also increases the runtime cost to evaluate the force. - -#### Many-Body - -The many-body (or *n*-body) force applies mutually amongst all [nodes](#simulation_nodes). It can be used to simulate gravity (attraction) if the [strength](#manyBody_strength) is positive, or electrostatic charge (repulsion) if the strength is negative. This implementation uses quadtrees and the [Barnes–Hut approximation](https://en.wikipedia.org/wiki/Barnes–Hut_simulation) to greatly improve performance; the accuracy can be customized using the [theta](#manyBody_theta) parameter. - -Unlike links, which only affect two linked nodes, the charge force is global: every node affects every other node, even if they are on disconnected subgraphs. - -# d3.forceManyBody() [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js "Source") - -Creates a new many-body force with the default parameters. - -# manyBody.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L97 "Source") - -If *strength* is specified, sets the strength accessor to the specified number or function, re-evaluates the strength accessor for each node, and returns this force. A positive value causes nodes to attract each other, similar to gravity, while a negative value causes nodes to repel each other, similar to electrostatic charge. If *strength* is not specified, returns the current strength accessor, which defaults to: - -```js -function strength() { - return -30; -} -``` - -The strength accessor is invoked for each [node](#simulation_nodes) in the simulation, being passed the *node* and its zero-based *index*. The resulting number is then stored internally, such that the strength of each node is only recomputed when the force is initialized or when this method is called with a new *strength*, and not on every application of the force. - -# manyBody.theta([theta]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L109 "Source") - -If *theta* is specified, sets the Barnes–Hut approximation criterion to the specified number and returns this force. If *theta* is not specified, returns the current value, which defaults to 0.9. - -To accelerate computation, this force implements the [Barnes–Hut approximation](http://en.wikipedia.org/wiki/Barnes–Hut_simulation) which takes O(*n* log *n*) per application where *n* is the number of [nodes](#simulation_nodes). For each application, a [quadtree](https://github.com/d3/d3-quadtree) stores the current node positions; then for each node, the combined force of all other nodes on the given node is computed. For a cluster of nodes that is far away, the charge force can be approximated by treating the cluster as a single, larger node. The *theta* parameter determines the accuracy of the approximation: if the ratio *w* / *l* of the width *w* of the quadtree cell to the distance *l* from the node to the cell’s center of mass is less than *theta*, all nodes in the given cell are treated as a single node rather than individually. - -# manyBody.distanceMin([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L101 "Source") - -If *distance* is specified, sets the minimum distance between nodes over which this force is considered. If *distance* is not specified, returns the current minimum distance, which defaults to 1. A minimum distance establishes an upper bound on the strength of the force between two nearby nodes, avoiding instability. In particular, it avoids an infinitely-strong force if two nodes are exactly coincident; in this case, the direction of the force is random. - -# manyBody.distanceMax([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L105 "Source") - -If *distance* is specified, sets the maximum distance between nodes over which this force is considered. If *distance* is not specified, returns the current maximum distance, which defaults to infinity. Specifying a finite maximum distance improves performance and produces a more localized layout. - -#### Positioning - -The [*x*](#forceX)- and [*y*](#forceY)-positioning forces push nodes towards a desired position along the given dimension with a configurable strength. The [*radial*](#forceRadial) force is similar, except it pushes nodes towards the closest point on a given circle. The strength of the force is proportional to the one-dimensional distance between the node’s position and the target position. While these forces can be used to position individual nodes, they are intended primarily for global forces that apply to all (or most) nodes. - -# d3.forceX([x]) [<>](https://github.com/d3/d3-force/blob/master/src/x.js "Source") - -Creates a new positioning force along the *x*-axis towards the given position [*x*](#x_x).

A few more examples: - -```js -d3.format(".0%")(0.123); // rounded percentage, "12%" -d3.format("($.2f")(-3.5); // localized fixed-point currency, "(£3.50)" -d3.format("+20")(42); // space-filled and signed, " +42" -d3.format(".^20")(42); // dot-filled and centered, ".........42........." -d3.format(".2s")(42e6); // SI-prefix with two significant digits, "42M" -d3.format("#x")(48879); // prefixed lowercase hexadecimal, "0xbeef" -d3.format(",.2r")(4223); // grouped thousands with two significant digits, "4,200" -``` - -See [*locale*.format](#locale_format) for a detailed specification, and try running [d3.formatSpecifier](#formatSpecifier) on the above formats to decode their meaning. - -## Installing - -If you use NPM, `npm install d3-format`. Otherwise, download the [latest release](https://github.com/d3/d3-format/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-format.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -Locale files are published to npm and can be loaded using [d3.json](https://github.com/d3/d3-request/blob/master/README.md#json). For example, to set Russian as the default locale: - -```js -d3.json("https://cdn.jsdelivr.net/npm/d3-format@1/locale/ru-RU.json", function(error, locale) { - if (error) throw error; - - d3.formatDefaultLocale(locale); - - var format = d3.format("$,"); - - console.log(format(1234.56)); // 1 234,56 руб. -}); -``` - -[Try d3-format in your browser.](https://observablehq.com/@d3/d3-format) - -## API Reference - -# d3.format(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/defaultLocale.js#L4 "Source") - -An alias for [*locale*.format](#locale_format) on the [default locale](#formatDefaultLocale). - -# d3.formatPrefix(specifier, value) [<>](https://github.com/d3/d3-format/blob/master/src/defaultLocale.js#L5 "Source") - -An alias for [*locale*.formatPrefix](#locale_formatPrefix) on the [default locale](#formatDefaultLocale). - -# locale.format(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/locale.js#L18 "Source") - -Returns a new format function for the given string *specifier*. The returned function takes a number as the only argument, and returns a string representing the formatted number. The general form of a specifier is: - -``` -[​[fill]align][sign][symbol][0][width][,][.precision][~][type] -``` - -The *fill* can be any character. The presence of a fill character is signaled by the *align* character following it, which must be one of the following: - -* `>` - Forces the field to be right-aligned within the available space. (Default behavior). -* `<` - Forces the field to be left-aligned within the available space. -* `^` - Forces the field to be centered within the available space. -* `=` - like `>`, but with any sign and symbol to the left of any padding. - -The *sign* can be: - -* `-` - nothing for zero or positive and a minus sign for negative. (Default behavior.) -* `+` - a plus sign for zero or positive and a minus sign for negative. -* `(` - nothing for zero or positive and parentheses for negative. -* ` ` (space) - a space for zero or positive and a minus sign for negative. - -The *symbol* can be: - -* `$` - apply currency symbols per the locale definition. -* `#` - for binary, octal, or hexadecimal notation, prefix by `0b`, `0o`, or `0x`, respectively. - -The *zero* (`0`) option enables zero-padding; this implicitly sets *fill* to `0` and *align* to `=`. The *width* defines the minimum field width; if not specified, then the width will be determined by the content. The *comma* (`,`) option enables the use of a group separator, such as a comma for thousands. - -Depending on the *type*, the *precision* either indicates the number of digits that follow the decimal point (types `f` and `%`), or the number of significant digits (types `​`, `e`, `g`, `r`, `s` and `p`). If the precision is not specified, it defaults to 6 for all types except `​` (none), which defaults to 12. Precision is ignored for integer formats (types `b`, `o`, `d`, `x`, `X` and `c`). See [precisionFixed](#precisionFixed) and [precisionRound](#precisionRound) for help picking an appropriate precision. - -The `~` option trims insignificant trailing zeros across all format types. This is most commonly used in conjunction with types `r`, `e`, `s` and `%`. For example: - -```js -d3.format("s")(1500); // "1.50000k" -d3.format("~s")(1500); // "1.5k" -``` - -The available *type* values are: - -* `e` - exponent notation. -* `f` - fixed point notation. -* `g` - either decimal or exponent notation, rounded to significant digits. -* `r` - decimal notation, rounded to significant digits. -* `s` - decimal notation with an [SI prefix](#locale_formatPrefix), rounded to significant digits. -* `%` - multiply by 100, and then decimal notation with a percent sign. -* `p` - multiply by 100, round to significant digits, and then decimal notation with a percent sign. -* `b` - binary notation, rounded to integer. -* `o` - octal notation, rounded to integer. -* `d` - decimal notation, rounded to integer. -* `x` - hexadecimal notation, using lower-case letters, rounded to integer. -* `X` - hexadecimal notation, using upper-case letters, rounded to integer. -* `c` - converts the integer to the corresponding unicode character before printing. - -The type `​` (none) is also supported as shorthand for `~g` (with a default precision of 12 instead of 6), and the type `n` is shorthand for `,g`. For the `g`, `n` and `​` (none) types, decimal notation is used if the resulting string would have *precision* or fewer digits; otherwise, exponent notation is used. For example: - -```js -d3.format(".2")(42); // "42" -d3.format(".2")(4.2); // "4.2" -d3.format(".1")(42); // "4e+1" -d3.format(".1")(4.2); // "4" -``` - -# locale.formatPrefix(specifier, value) [<>](https://github.com/d3/d3-format/blob/master/src/locale.js#L127 "Source") - -Equivalent to [*locale*.format](#locale_format), except the returned function will convert values to the units of the appropriate [SI prefix](https://en.wikipedia.org/wiki/Metric_prefix#List_of_SI_prefixes) for the specified numeric reference *value* before formatting in fixed point notation. The following prefixes are supported: - -* `y` - yocto, 10⁻²⁴ -* `z` - zepto, 10⁻²¹ -* `a` - atto, 10⁻¹⁸ -* `f` - femto, 10⁻¹⁵ -* `p` - pico, 10⁻¹² -* `n` - nano, 10⁻⁹ -* `µ` - micro, 10⁻⁶ -* `m` - milli, 10⁻³ -* `​` (none) - 10⁰ -* `k` - kilo, 10³ -* `M` - mega, 10⁶ -* `G` - giga, 10⁹ -* `T` - tera, 10¹² -* `P` - peta, 10¹⁵ -* `E` - exa, 10¹⁸ -* `Z` - zetta, 10²¹ -* `Y` - yotta, 10²⁴ - -Unlike [*locale*.format](#locale_format) with the `s` format type, this method returns a formatter with a consistent SI prefix, rather than computing the prefix dynamically for each number. In addition, the *precision* for the given *specifier* represents the number of digits past the decimal point (as with `f` fixed point notation), not the number of significant digits. For example: - -```js -var f = d3.formatPrefix(",.0", 1e-6); -f(0.00042); // "420µ" -f(0.0042); // "4,200µ" -``` - -This method is useful when formatting multiple numbers in the same units for easy comparison. See [precisionPrefix](#precisionPrefix) for help picking an appropriate precision, and [bl.ocks.org/9764126](http://bl.ocks.org/mbostock/9764126) for an example. - -# d3.formatSpecifier(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/formatSpecifier.js "Source") - -Parses the specified *specifier*, returning an object with exposed fields that correspond to the [format specification mini-language](#locale_format) and a toString method that reconstructs the specifier.

For example, you might compute an appropriate precision based on the numbers you want to format using [precisionFixed](#precisionFixed) and then create a new format: - -```js -var s = d3.formatSpecifier("f"); -s.precision = d3.precisionFixed(0.01); -var f = d3.format(s); -f(42); // "42.00"; -``` - -# new d3.FormatSpecifier(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/formatSpecifier.js "Source") - -Given the specified *specifier* object, returning an object with exposed fields that correspond to the [format specification mini-language](#locale_format) and a toString method that reconstructs the specifier.

The *step* represents the minimum absolute difference between values that will be formatted. (This assumes that the values to be formatted are also multiples of *step*.) For example, given the numbers 1, 1.5, and 2, the *step* should be 0.5 and the suggested precision is 1: - -```js -var p = d3.precisionFixed(0.5), - f = d3.format("." + p + "f"); -f(1); // "1.0" -f(1.5); // "1.5" -f(2); // "2.0" -``` - -Whereas for the numbers 1, 2 and 3, the *step* should be 1 and the suggested precision is 0: - -```js -var p = d3.precisionFixed(1), - f = d3.format("." + p + "f"); -f(1); // "1" -f(2); // "2" -f(3); // "3" -``` - -Note: for the `%` format type, subtract two: - -```js -var p = Math.max(0, d3.precisionFixed(0.05) - 2), - f = d3.format("." + p + "%"); -f(0.45); // "45%" -f(0.50); // "50%" -f(0.55); // "55%" -``` - -# d3.precisionPrefix(step, value) [<>](https://github.com/d3/d3-format/blob/master/src/precisionPrefix.js "Source") - -Returns a suggested decimal precision for use with [*locale*.formatPrefix](#locale_formatPrefix) given the specified numeric *step* and reference *value*. The *step* represents the minimum absolute difference between values that will be formatted, and *value* determines which SI prefix will be used.

For example, given the numbers 1.1e6, 1.2e6, and 1.3e6, the *step* should be 1e5, the *value* could be 1.3e6, and the suggested precision is 1: - -```js -var p = d3.precisionPrefix(1e5, 1.3e6), - f = d3.formatPrefix("." + p, 1.3e6); -f(1.1e6); // "1.1M" -f(1.2e6); // "1.2M" -f(1.3e6); // "1.3M" -``` - -# d3.precisionRound(step, max) [<>](https://github.com/d3/d3-format/blob/master/src/precisionRound.js "Source") - -Returns a suggested decimal precision for format types that round to significant digits given the specified numeric *step* and *max* values.

For example, given the numbers 0.99, 1.0, and 1.01, the *step* should be 0.01, the *max* should be 1.01, and the suggested precision is 3: - -```js -var p = d3.precisionRound(0.01, 1.01), - f = d3.format("." + p + "r"); -f(0.99); // "0.990" -f(1.0); // "1.00" -f(1.01); // "1.01" -``` - -Whereas for the numbers 0.9, 1.0, and 1.1, the *step* should be 0.1, the *max* should be 1.1, and the suggested precision is 2: - -```js -var p = d3.precisionRound(0.1, 1.1), - f = d3.format("." + p + "r"); -f(0.9); // "0.90" -f(1.0); // "1.0" -f(1.1); // "1.1" -``` - -Note: for the `e` format type, subtract one: - -```js -var p = Math.max(0, d3.precisionRound(0.01, 1.01) - 1), - f = d3.format("." + p + "e"); -f(0.01); // "1.00e-2" -f(1.01); // "1.01e+0" -``` - -### Locales - -# d3.formatLocale(definition) [<>](https://github.com/d3/d3-format/blob/master/src/locale.js "Source") - -Returns a *locale* object for the specified *definition* with [*locale*.format](#locale_format) and [*locale*.formatPrefix](#locale_formatPrefix) methods.

# d3.bisector(comparator) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js "Source") - -Returns a new bisector using the specified *accessor* or *comparator* function. This method can be used to bisect arrays of objects instead of being limited to simple arrays of primitives.

Note that the comparator is always passed the search value *x* as the second argument. Use a comparator rather than an accessor if you want values to be sorted in an order different than natural order, such as in descending rather than ascending order. - -# bisector.left(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L6 "Source") - -Equivalent to [bisectLeft](#bisectLeft), but uses this bisector’s associated comparator. - -# bisector.right(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L16 "Source") - -Equivalent to [bisectRight](#bisectRight), but uses this bisector’s associated comparator. - -# d3.ascending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/ascending.js "Source") - -Returns -1 if *a* is less than *b*, or 1 if *a* is greater than *b*, or 0. This is the comparator function for natural order, and can be used in conjunction with the built-in [*array*.sort](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) method to arrange elements in ascending order. It is implemented as: - -```js -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -# d3.descending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/descending.js "Source") - -Returns -1 if *a* is greater than *b*, or 1 if *a* is less than *b*, or 0. This is the comparator function for reverse natural order, and can be used in conjunction with the built-in array sort method to arrange elements in descending order. It is implemented as: - -```js -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -### Transformations - -Methods for transforming arrays and for generating new arrays. - -# d3.cross(a, b[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/cross.js "Source") - -Returns the [Cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) of the two arrays *a* and *b*. For each element *i* in the specified array *a* and each element *j* in the specified array *b*, in order, invokes the specified *reducer* function passing the element *i* and element *j*. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.cross([1, 2], ["x", "y"]); // returns [[1, "x"], [1, "y"], [2, "x"], [2, "y"]] -d3.cross([1, 2], ["x", "y"], (a, b) => a + b); // returns ["1x", "1y", "2x", "2y"] -``` - -# d3.merge(arrays) [<>](https://github.com/d3/d3-array/blob/master/src/merge.js "Source") - -Merges the specified *arrays* into a single array. This method is similar to the built-in array concat method; the only difference is that it is more convenient when you have an array of arrays. - -```js -d3.merge([[1], [2, 3]]); // returns [1, 2, 3] -``` - -# d3.pairs(array[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/pairs.js "Source") - -For each adjacent pair of elements in the specified *array*, in order, invokes the specified *reducer* function passing the element *i* and element *i* - 1. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.pairs([1, 2, 3, 4]); // returns [[1, 2], [2, 3], [3, 4]] -d3.pairs([1, 2, 3, 4], (a, b) => b - a); // returns [1, 1, 1]; -``` - -If the specified array has fewer than two elements, returns the empty array. - -# d3.permute(array, indexes) [<>](https://github.com/d3/d3-array/blob/master/src/permute.js "Source") - -Returns a permutation of the specified *array* using the specified array of *indexes*. The returned array contains the corresponding element in array for each index in indexes, in order. For example, permute(["a", "b", "c"], [1, 2, 0]) -returns ["b", "c", "a"]. It is acceptable for the array of indexes to be a different length from the array of elements, and for indexes to be duplicated or omitted. - -This method can also be used to extract the values from an object into an array with a stable order. Extracting keyed values in order can be useful for generating data arrays in nested selections. For example: - -```js -var object = {yield: 27, variety: "Manchuria", year: 1931, site: "University Farm"}, - fields = ["site", "variety", "yield"]; - -d3.permute(object, fields); // returns ["University Farm", "Manchuria", 27] -``` - -# d3.shuffle(array[, start[, stop]]) [<>](https://github.com/d3/d3-array/blob/master/src/shuffle.js "Source") - -Randomizes the order of the specified *array* in-place using the [Fisher–Yates shuffle](https://bost.ocks.org/mike/shuffle/) and returns the *array*. If *start* is specified, it is the starting index (inclusive) of the *array* to shuffle; if *start* is not specified, it defaults to zero. If *stop* is specified, it is the ending index (exclusive) of the *array* to shuffle; if *stop* is not specified, it defaults to *array*.length. For example, to shuffle the first ten elements of the *array*: shuffle(*array*, 0, 10). - -# d3.ticks(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js "Source") - -Returns an array of approximately *count* + 1 uniformly-spaced, nicely-rounded values between *start* and *stop* (inclusive). Each value is a power of ten multiplied by 1, 2 or 5. See also [d3.tickIncrement](#tickIncrement), [d3.tickStep](#tickStep) and [*linear*.ticks](https://github.com/d3/d3-scale/blob/master/README.md#linear_ticks). - -Ticks are inclusive in the sense that they may include the specified *start* and *stop* values if (and only if) they are exact, nicely-rounded values consistent with the inferred [step](#tickStep). More formally, each returned tick *t* satisfies *start* ≤ *t* and *t* ≤ *stop*. - -# d3.tickIncrement(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Like [d3.tickStep](#tickStep), except requires that *start* is always less than or equal to *step*, and if the tick step for the given *start*, *stop* and *count* would be less than one, returns the negative inverse tick step instead. This method is always guaranteed to return an integer, and is used by [d3.ticks](#ticks) to avoid guarantee that the returned tick values are represented as precisely as possible in IEEE 754 floating point. - -# d3.tickStep(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Returns the difference between adjacent tick values if the same arguments were passed to [d3.ticks](#ticks): a nicely-rounded value that is a power of ten multiplied by 1, 2 or 5. Note that due to the limited precision of IEEE 754 floating point, the returned value may not be exact decimals; use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption. - -# d3.range([start, ]stop[, step]) [<>](https://github.com/d3/d3-array/blob/master/src/range.js "Source") - -Returns an array containing an arithmetic progression, similar to the Python built-in [range](http://docs.python.org/library/functions.html#range). This method is often used to iterate over a sequence of uniformly-spaced numeric values, such as the indexes of an array or the ticks of a linear scale. (See also [d3.ticks](#ticks) for nicely-rounded values.) - -If *step* is omitted, it defaults to 1. If *start* is omitted, it defaults to 0. The *stop* value is exclusive; it is not included in the result. If *step* is positive, the last element is the largest *start* + *i* \* *step* less than *stop*; if *step* is negative, the last element is the smallest *start* + *i* \* *step* greater than *stop*. If the returned array would contain an infinite number of values, an empty range is returned. - -The arguments are not required to be integers; however, the results are more predictable if they are. The values in the returned array are defined as *start* + *i* \* *step*, where *i* is an integer from zero to one minus the total number of elements in the returned array. For example: - -```js -d3.range(0, 1, 0.2) // [0, 0.2, 0.4, 0.6000000000000001, 0.8] -``` - -This unexpected behavior is due to IEEE 754 double-precision floating point, which defines 0.2 * 3 = 0.6000000000000001. Use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption with appropriate rounding; see also [linear.tickFormat](https://github.com/d3/d3-scale/blob/master/README.md#linear_tickFormat) in [d3-scale](https://github.com/d3/d3-scale). - -Likewise, if the returned array should have a specific length, consider using [array.map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) on an integer range. For example: - -```js -d3.range(0, 1, 1 / 49); // BAD: returns 50 elements! -d3.range(49).map(function(d) { return d / 49; }); // GOOD: returns 49 elements. -``` - -# d3.transpose(matrix) [<>](https://github.com/d3/d3-array/blob/master/src/transpose.js "Source") - -Uses the [zip](#zip) operator as a two-dimensional [matrix transpose](http://en.wikipedia.org/wiki/Transpose). - -# d3.zip(arrays…) [<>](https://github.com/d3/d3-array/blob/master/src/zip.js "Source") - -Returns an array of arrays, where the *i*th array contains the *i*th element from each of the argument *arrays*. The returned array is truncated in length to the shortest array in *arrays*. If *arrays* contains only a single array, the returned array contains one-element arrays. With no arguments, the returned array is empty. - -```js -d3.zip([1, 2], [3, 4]); // returns [[1, 3], [2, 4]] -``` - -### Histograms - -[Histogram](http://bl.ocks.org/mbostock/3048450) - -Histograms bin many discrete samples into a smaller number of consecutive, non-overlapping intervals. They are often used to visualize the distribution of numerical data. - -# d3.histogram() [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js "Source") - -Constructs a new histogram generator with the default settings. - -# histogram(data) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L14 "Source") - -Computes the histogram for the given array of *data* samples. Returns an array of bins, where each bin is an array containing the associated elements from the input *data*. Thus, the `length` of the bin is the number of elements in that bin. Each bin has two additional attributes: - -* `x0` - the lower bound of the bin (inclusive). -* `x1` - the upper bound of the bin (exclusive, except for the last bin). - -# histogram.value([value]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L58 "Source") - -If *value* is specified, sets the value accessor to the specified function or constant and returns this histogram generator. If *value* is not specified, returns the current value accessor, which defaults to the identity function. - -When a histogram is [generated](#_histogram), the value accessor will be invoked for each element in the input data array, being passed the element `d`, the index `i`, and the array `data` as three arguments. The default value accessor assumes that the input data are orderable (comparable), such as numbers or dates. If your data are not, then you should specify an accessor that returns the corresponding orderable value for a given datum. - -This is similar to mapping your data to values before invoking the histogram generator, but has the benefit that the input data remains associated with the returned bins, thereby making it easier to access other fields of the data. - -# histogram.domain([domain]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L62 "Source") - -If *domain* is specified, sets the domain accessor to the specified function or array and returns this histogram generator. If *domain* is not specified, returns the current domain accessor, which defaults to [extent](#extent). The histogram domain is defined as an array [*min*, *max*], where *min* is the minimum observable value and *max* is the maximum observable value; both values are inclusive. Any value outside of this domain will be ignored when the histogram is [generated](#_histogram). - -For example, if you are using the the histogram in conjunction with a [linear scale](https://github.com/d3/d3-scale/blob/master/README.md#linear-scales) `x`, you might say: - -```js -var histogram = d3.histogram() - .domain(x.domain()) - .thresholds(x.ticks(20)); -``` - -You can then compute the bins from an array of numbers like so: - -```js -var bins = histogram(numbers); -``` - -Note that the domain accessor is invoked on the materialized array of [values](#histogram_value), not on the input data array. - -# histogram.thresholds([count]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") -
# histogram.thresholds([thresholds]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") - -If *thresholds* is specified, sets the [threshold generator](#histogram-thresholds) to the specified function or array and returns this histogram generator. If *thresholds* is not specified, returns the current threshold generator, which by default implements [Sturges’ formula](#thresholdSturges). (Thus by default, the histogram values must be numbers!) Thresholds are defined as an array of values [*x0*, *x1*, …]. Any value less than *x0* will be placed in the first bin; any value greater than or equal to *x0* but less than *x1* will be placed in the second bin; and so on. Thus, the [generated histogram](#_histogram) will have *thresholds*.length + 1 bins. See [histogram thresholds](#histogram-thresholds) for more information. - -Any threshold values outside the [domain](#histogram_domain) are ignored. The first *bin*.x0 is always equal to the minimum domain value, and the last *bin*.x1 is always equal to the maximum domain value. - -If a *count* is specified instead of an array of *thresholds*, then the [domain](#histogram_domain) will be uniformly divided into approximately *count* bins; see [ticks](#ticks). - -### Histogram Thresholds - -These functions are typically not used directly; instead, pass them to [*histogram*.thresholds](#histogram_thresholds). You may also implement your own threshold generator taking three arguments: the array of input [*values*](#histogram_value) derived from the data, and the [observable domain](#histogram_domain) represented as *min* and *max*. The generator may then return either the array of numeric thresholds or the *count* of bins; in the latter case the domain is divided uniformly into approximately *count* bins; see [ticks](#ticks). - -# d3.thresholdFreedmanDiaconis(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/freedmanDiaconis.js "Source") - -Returns the number of bins according to the [Freedman–Diaconis rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdScott(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/scott.js "Source") - -Returns the number of bins according to [Scott’s normal reference rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdSturges(values) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/sturges.js "Source") - -Returns the number of bins according to [Sturges’ formula](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. diff --git a/node_modules/d3-geo-projection/node_modules/d3-array/dist/d3-array.js b/node_modules/d3-geo-projection/node_modules/d3-array/dist/d3-array.js deleted file mode 100644 index 89d17e7..0000000 --- a/node_modules/d3-geo-projection/node_modules/d3-array/dist/d3-array.js +++ /dev/null @@ -1,590 +0,0 @@ -// https://d3js.org/d3-array/ v1.2.4 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(factory((global.d3 = global.d3 || {}))); -}(this, (function (exports) { 'use strict'; - -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} - -function bisector(compare) { - if (compare.length === 1) compare = ascendingComparator(compare); - return { - left: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) < 0) lo = mid + 1; - else hi = mid; - } - return lo; - }, - right: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) > 0) hi = mid; - else lo = mid + 1; - } - return lo; - } - }; -} - -function ascendingComparator(f) { - return function(d, x) { - return ascending(f(d), x); - }; -} - -var ascendingBisect = bisector(ascending); -var bisectRight = ascendingBisect.right; -var bisectLeft = ascendingBisect.left; - -function pairs(array, f) { - if (f == null) f = pair; - var i = 0, n = array.length - 1, p = array[0], pairs = new Array(n < 0 ? 0 : n); - while (i < n) pairs[i] = f(p, p = array[++i]); - return pairs; -} - -function pair(a, b) { - return [a, b]; -} - -function cross(values0, values1, reduce) { - var n0 = values0.length, - n1 = values1.length, - values = new Array(n0 * n1), - i0, - i1, - i, - value0; - - if (reduce == null) reduce = pair; - - for (i0 = i = 0; i0 < n0; ++i0) { - for (value0 = values0[i0], i1 = 0; i1 < n1; ++i1, ++i) { - values[i] = reduce(value0, values1[i1]); - } - } - - return values; -} - -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} - -function number(x) { - return x === null ?

For instance, spherical Mercator: - -```js -function mercator(x, y) { - return [x, Math.log(Math.tan(Math.PI / 4 + y / 2))]; -} -``` - -This is a reasonable *mathematical* approach if your geometry consists of continuous, infinite point sets. Yet computers do not have infinite memory, so we must instead work with discrete geometry such as polygons and polylines! - -Discrete geometry makes the challenge of projecting from the sphere to the plane much harder. The edges of a spherical polygon are [geodesics](https://en.wikipedia.org/wiki/Geodesic) (segments of great circles), not straight lines. Projected to the plane, geodesics are curves in all map projections except [gnomonic](#geoGnomonic), and thus accurate projection requires interpolation along each arc. D3 uses [adaptive sampling](https://bl.ocks.org/mbostock/3795544) inspired by a popular [line simplification method](https://bost.ocks.org/mike/simplify/) to balance accuracy and performance. - -The projection of polygons and polylines must also deal with the topological differences between the sphere and the plane. Some projections require cutting geometry that [crosses the antimeridian](https://bl.ocks.org/mbostock/3788999), while others require [clipping geometry to a great circle](https://bl.ocks.org/mbostock/3021474). - -Spherical polygons also require a [winding order convention](https://bl.ocks.org/mbostock/a7bdfeb041e850799a8d3dce4d8c50c8) to determine which side of the polygon is the inside: the exterior ring for polygons smaller than a hemisphere must be clockwise, while the exterior ring for polygons [larger than a hemisphere](https://bl.ocks.org/mbostock/6713736) must be anticlockwise. Interior rings representing holes must use the opposite winding order of their exterior ring. This winding order convention is also used by [TopoJSON](https://github.com/topojson) and [ESRI shapefiles](https://github.com/mbostock/shapefile); however, it is the **opposite** convention of GeoJSON’s [RFC 7946](https://tools.ietf.org/html/rfc7946#section-3.1.6). (Also note that standard GeoJSON WGS84 uses planar equirectangular coordinates, not spherical coordinates, and thus may require [stitching](https://github.com/d3/d3-geo-projection/blob/master/README.md#geostitch) to remove antimeridian cuts.) - -D3’s approach affords great expressiveness: you can choose the right projection, and the right aspect, for your data. D3 supports a wide variety of common and [unusual map projections](https://github.com/d3/d3-geo-projection). For more, see Part 2 of [The Toolmaker’s Guide](https://vimeo.com/106198518#t=20m0s). - -D3 uses [GeoJSON](http://geojson.org/geojson-spec.html) to represent geographic features in JavaScript. (See also [TopoJSON](https://github.com/mbostock/topojson), an extension of GeoJSON that is significantly more compact and encodes topology.) To convert shapefiles to GeoJSON, use [shp2json](https://github.com/mbostock/shapefile/blob/master/README.md#shp2json), part of the [shapefile package](https://github.com/mbostock/shapefile).

While the radius is commonly specified as a number constant, it may also be specified as a function which is computed per feature, being passed the any arguments passed to the [path generator](#_path). For example, if your GeoJSON data has additional properties, you might access those properties inside the radius function to vary the point size; alternatively, you could [d3.symbol](https://github.com/d3/d3-shape#symbols) and a [projection](#geoProjection) for greater flexibility. - -### Projections - -Projections transform spherical polygonal geometry to planar polygonal geometry. D3 provides implementations of several classes of standard projections: - -* [Azimuthal](#azimuthal-projections) -* [Composite](#composite-projections) -* [Conic](#conic-projections) -* [Cylindrical](#cylindrical-projections) - -For many more projections, see [d3-geo-projection](https://github.com/d3/d3-geo-projection). You can implement [custom projections](#raw-projections) using [d3.geoProjection](#geoProjection) or [d3.geoProjectionMutator](#geoProjectionMutator). - -# projection(point) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a new array \[*x*, *y*\] (typically in pixels) representing the projected point of the given *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. May return null if the specified *point* has no defined projected position, such as when the point is outside the clipping bounds of the projection. - -# projection.invert(point) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the unprojected point of the given projected *point*. The point must be specified as a two-element array \[*x*, *y*\] (typically in pixels). May return null if the specified *point* has no defined projected position, such as when the point is outside the clipping bounds of the projection. - -This method is only defined on invertible projections. - -# projection.stream(stream) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a [projection stream](#streams) for the specified output *stream*. Any input geometry is projected before being streamed to the output stream. A typical projection involves several geometry transformations: the input geometry is first converted to radians, rotated on three axes, clipped to the small circle or cut along the antimeridian, and lastly projected to the plane with adaptive resampling, scale and translation. - -# projection.preclip([preclip]) - -If *preclip* is specified, sets the projection’s spherical clipping to the specified function and returns the projection. If *preclip* is not specified, returns the current spherical clipping function (see [preclip](#preclip)). - -# projection.postclip([postclip]) - -If *postclip* is specified, sets the projection’s cartesian clipping to the specified function and returns the projection.

If *angle* is null, switches to [antimeridian cutting](https://bl.ocks.org/mbostock/3788999) rather than small-circle clipping. If *angle* is not specified, returns the current clip angle which defaults to null. Small-circle clipping is independent of viewport clipping via [*projection*.clipExtent](#projection_clipExtent). - -See also [*projection*.preclip](#projection_preclip), [d3.geoClipAntimeridian](#geoClipAntimeridian), [d3.geoClipCircle](#geoClipCircle). - -# projection.clipExtent([extent]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *extent* is specified, sets the projection’s viewport clip extent to the specified bounds in pixels and returns the projection. The *extent* bounds are specified as an array \[\[x₀, y₀\], \[x₁, y₁\]\], where x₀ is the left-side of the viewport, y₀ is the top, x₁ is the right and y₁ is the bottom. If *extent* is null, no viewport clipping is performed. If *extent* is not specified, returns the current viewport clip extent which defaults to null.

If *scale* is not specified, returns the current scale factor; the default scale is projection-specific. The scale factor corresponds linearly to the distance between projected points; however, absolute scale factors are not equivalent across projections. - -# projection.translate([translate]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *translate* is specified, sets the projection’s translation offset to the specified two-element array [tx, ty] and returns the projection. If *translate* is not specified, returns the current translation offset which defaults to [480, 250]. The translation offset determines the pixel coordinates of the projection’s [center](#projection_center). The default translation offset places ⟨0°,0°⟩ at the center of a 960×500 area. - -# projection.center([center]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *center* is specified, sets the projection’s center to the specified *center*, a two-element array of [*longitude*, *latitude*] in degrees and returns the projection.

If *angle* is not specified, returns the projection’s current angle, which defaults to 0°. Note that it may be faster to rotate during rendering (e.g., using [*context*.rotate](https://developer.mozilla.org/docs/Web/API/CanvasRenderingContext2D/rotate)) rather than during projection. - -# projection.reflectX([reflect]) - -If *reflect* is specified, sets whether or not the *x*-dimension is reflected (negated) in the output. If *reflect* is not specified, returns true if *x*-reflection is enabled, which defaults to false. This can be useful to display sky and astronomical data with the orb seen from below: right ascension (eastern direction) will point to the left when North is pointing up. - -# projection.reflectY([reflect]) - -If *reflect* is specified, sets whether or not the *y*-dimension is reflected (negated) in the output. If *reflect* is not specified, returns true if *y*-reflection is enabled, which defaults to false. This is especially useful for transforming from standard [spatial reference systems](https://en.wikipedia.org/wiki/Spatial_reference_system), which treat positive *y* as pointing up, to display coordinate systems such as Canvas and SVG, which treat positive *y* as pointing down. - -# projection.rotate([angles]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *rotation* is specified, sets the projection’s [three-axis spherical rotation](https://bl.ocks.org/mbostock/4282586) to the specified *angles*, which must be a two- or three-element array of numbers [*lambda*, *phi*, *gamma*] specifying the rotation angles in degrees about [each spherical axis](https://bl.ocks.org/mbostock/4282586). (These correspond to [yaw, pitch and roll](https://en.wikipedia.org/wiki/Aircraft_principal_axes).) If the rotation angle *gamma* is omitted, it defaults to 0. See also [d3.geoRotation](#geoRotation). If *rotation* is not specified, returns the current rotation which defaults [0, 0, 0]. - -# projection.precision([precision]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *precision* is specified, sets the threshold for the projection’s [adaptive resampling](https://bl.ocks.org/mbostock/3795544) to the specified value in pixels and returns the projection. This value corresponds to the [Douglas–Peucker](https://en.wikipedia.org/wiki/Ramer–Douglas–Peucker_algorithm) distance. If *precision* is not specified, returns the projection’s current resampling precision which defaults to √0.5 ≅ 0.70710… - -# projection.fitExtent(extent, object) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Sets the projection’s [scale](#projection_scale) and [translate](#projection_translate) to fit the specified GeoJSON *object* in the center of the given *extent*. The extent is specified as an array \[\[x₀, y₀\], \[x₁, y₁\]\], where x₀ is the left side of the bounding box, y₀ is the top, x₁ is the right and y₁ is the bottom. Returns the projection. - -For example, to scale and translate the [New Jersey State Plane projection](https://bl.ocks.org/mbostock/5126418) to fit a GeoJSON object *nj* in the center of a 960×500 bounding box with 20 pixels of padding on each side: - -```js -var projection = d3.geoTransverseMercator() - .rotate([74 + 30 / 60, -38 - 50 / 60]) - .fitExtent([[20, 20], [940, 480]], nj); -``` - -Any [clip extent](#projection_clipExtent) is ignored when determining the new scale and translate. The [precision](#projection_precision) used to compute the bounding box of the given *object* is computed at an effective scale of 150. - -# projection.fitSize(size, object) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -A convenience method for [*projection*.fitExtent](#projection_fitExtent) where the top-left corner of the extent is [0, 0].

They are exposed here to facilitate the derivation of related projections. Raw projections take spherical coordinates \[*lambda*, *phi*\] in radians (not degrees!) and return a point \[*x*, *y*\], typically in the unit square centered around the origin. - -# project(lambda, phi) - -Projects the specified point [lambda, phi] in radians, returning a new point \[*x*, *y*\] in unitless coordinates. - -# project.invert(x, y) - -The inverse of [*project*](#_project). - -# d3.geoProjection(project) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Constructs a new projection from the specified [raw projection](#_project), *project*. The *project* function takes the *longitude* and *latitude* of a given point in [radians](http://mathworld.wolfram.com/Radian.html), often referred to as *lambda* (λ) and *phi* (φ), and returns a two-element array \[*x*, *y*\] representing its unit projection. The *project* function does not need to scale or translate the point, as these are applied automatically by [*projection*.scale](#projection_scale), [*projection*.translate](#projection_translate), and [*projection*.center](#projection_center). Likewise, the *project* function does not need to perform any spherical rotation, as [*projection*.rotate](#projection_rotate) is applied prior to projection. - -For example, a spherical Mercator projection can be implemented as: - -```js -var mercator = d3.geoProjection(function(x, y) { - return [x, Math.log(Math.tan(Math.PI / 4 + y / 2))]; -}); -``` - -If the *project* function exposes an *invert* method, the returned projection will also expose [*projection*.invert](#projection_invert). - -# d3.geoProjectionMutator(factory) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Constructs a new projection from the specified [raw projection](#_project) *factory* and returns a *mutate* function to call whenever the raw projection changes. The *factory* must return a raw projection. The returned *mutate* function returns the wrapped projection. For example, a conic projection typically has two configurable parallels. A suitable *factory* function, such as [d3.geoConicEqualAreaRaw](#geoConicEqualAreaRaw), would have the form: - -```js -// y0 and y1 represent two parallels -function conicFactory(phi0, phi1) { - return function conicRaw(lambda, phi) { - return […, …]; - }; -} -``` - -Using d3.geoProjectionMutator, you can implement a standard projection that allows the parallels to be changed, reassigning the raw projection used internally by [d3.geoProjection](#geoProjection): - -```js -function conicCustom() { - var phi0 = 29.5, - phi1 = 45.5, - mutate = d3.geoProjectionMutator(conicFactory), - projection = mutate(phi0, phi1); - - projection.parallels = function(_) { - return arguments.length ? mutate(phi0 = +_[0], phi1 = +_[1]) : [phi0, phi1]; - }; - - return projection; -} -``` - -When creating a mutable projection, the *mutate* function is typically not exposed. - -### Spherical Math - -# d3.geoArea(object) [<>](https://github.com/d3/d3-geo/blob/master/src/area.js "Source") - -Returns the spherical area of the specified GeoJSON *object* in [steradians](http://mathworld.wolfram.com/Steradian.html).

The bounding box is represented by a two-dimensional array: \[\[*left*, *bottom*], \[*right*, *top*\]\], where *left* is the minimum longitude, *bottom* is the minimum latitude, *right* is maximum longitude, and *top* is the maximum latitude. All coordinates are given in degrees. (Note that in projected planar coordinates, the minimum latitude is typically the maximum *y*-value, and the maximum latitude is typically the minimum *y*-value.) This is the spherical equivalent of [*path*.bounds](#path_bounds). - -# d3.geoCentroid(object) [<>](https://github.com/d3/d3-geo/blob/master/src/centroid.js "Source") - -Returns the spherical centroid of the specified GeoJSON *object*. This is the spherical equivalent of [*path*.centroid](#path_centroid). - -# d3.geoDistance(a, b) [<>](https://github.com/d3/d3-geo/blob/master/src/distance.js "Source") - -Returns the great-arc distance in [radians](http://mathworld.wolfram.com/Radian.html) between the two points *a* and *b*.

This is the spherical equivalent of [*path*.measure](#path_measure) given a LineString of two points. - -# d3.geoLength(object) [<>](https://github.com/d3/d3-geo/blob/master/src/length.js "Source") - -Returns the great-arc length of the specified GeoJSON *object* in [radians](http://mathworld.wolfram.com/Radian.html). For polygons, returns the perimeter of the exterior ring plus that of any interior rings. This is the spherical equivalent of [*path*.measure](#path_measure). - -# d3.geoInterpolate(a, b) [<>](https://github.com/d3/d3-geo/blob/master/src/interpolate.js "Source") - -Returns an interpolator function given two points *a* and *b*. Each point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. The returned interpolator function takes a single argument *t*, where *t* is a number ranging from 0 to 1; a value of 0 returns the point *a*, while a value of 1 returns the point *b*. Intermediate values interpolate from *a* to *b* along the great arc that passes through both *a* and *b*. If *a* and *b* are antipodes, an arbitrary great arc is chosen. - -# d3.geoContains(object, point) [<>](https://github.com/d3/d3-geo/blob/master/src/contains.js "Source") - -Returns true if and only if the specified GeoJSON *object* contains the specified *point*, or false if the *object* does not contain the *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees.

(These correspond to [yaw, pitch and roll](https://en.wikipedia.org/wiki/Aircraft_principal_axes).) If the rotation angle *gamma* is omitted, it defaults to 0. See also [*projection*.rotate](#projection_rotate). - -# rotation(point) [<>](https://github.com/d3/d3-geo/blob/master/src/rotation.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the rotated point of the given *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. - -# rotation.invert(point) [<>](https://github.com/d3/d3-geo/blob/master/src/rotation.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the point of the given rotated *point*; the inverse of [*rotation*](#_rotation).

Equivalent to: - -```js -function geoGraticule10() { - return d3.geoGraticule()(); -} -``` - -### Streams - -D3 transforms geometry using a sequence of function calls, rather than materializing intermediate representations, to minimize overhead. Streams must implement several methods to receive input geometry. Streams are inherently stateful; the meaning of a [point](#point) depends on whether the point is inside of a [line](#lineStart), and likewise a line is distinguished from a ring by a [polygon](#polygonStart). Despite the name “stream”, these method calls are currently synchronous. - -# d3.geoStream(object, stream) [<>](https://github.com/d3/d3-geo/blob/master/src/stream.js "Source") - -Streams the specified [GeoJSON](http://geojson.org) *object* to the specified [projection *stream*](#projection-streams). While both features and geometry objects are supported as input, the stream interface only describes the geometry, and thus additional feature properties are not visible to streams. - -# stream.point(x, y[, z]) - -Indicates a point with the specified coordinates *x* and *y* (and optionally *z*). The coordinate system is unspecified and implementation-dependent; for example, [projection streams](https://github.com/d3/d3-geo-projection) require spherical coordinates in degrees as input. Outside the context of a polygon or line, a point indicates a point geometry object ([Point](http://www.geojson.org/geojson-spec.html#point) or [MultiPoint](http://www.geojson.org/geojson-spec.html#multipoint)). Within a line or polygon ring, the point indicates a control point. - -# stream.lineStart() - -Indicates the start of a line or ring. Within a polygon, indicates the start of a ring. The first ring of a polygon is the exterior ring, and is typically clockwise. Any subsequent rings indicate holes in the polygon, and are typically counterclockwise. - -# stream.lineEnd() - -Indicates the end of a line or ring. Within a polygon, indicates the end of a ring. Unlike GeoJSON, the redundant closing coordinate of a ring is *not* indicated via [point](#point), and instead is implied via lineEnd within a polygon. Thus, the given polygon input: - -```json -{ - "type": "Polygon", - "coordinates": [ - [[0, 0], [0, 1], [1, 1], [1, 0], [0, 0]] - ] -} -``` - -Will produce the following series of method calls on the stream: - -```js -stream.polygonStart(); -stream.lineStart(); -stream.point(0, 0); -stream.point(0, 1); -stream.point(1, 1); -stream.point(1, 0); -stream.lineEnd(); -stream.polygonEnd(); -``` - -# stream.polygonStart() - -Indicates the start of a polygon. The first line of a polygon indicates the exterior ring, and any subsequent lines indicate interior holes. - -# stream.polygonEnd() - -Indicates the end of a polygon. - -# stream.sphere() - -Indicates the sphere (the globe; the unit sphere centered at ⟨0,0,0⟩). - -### Transforms - -Transforms are a generalization of projections. Transform implement [*projection*.stream](#projection_stream) and can be passed to [*path*.projection](#path_projection). However, they only implement a subset of the other projection methods, and represent arbitrary geometric transformations rather than projections from spherical to planar coordinates. - -# d3.geoTransform(methods) [<>](https://github.com/d3/d3-geo/blob/master/src/transform.js "Source") - -Defines an arbitrary transform using the methods defined on the specified *methods* object. Any undefined methods will use pass-through methods that propagate inputs to the output stream. For example, to reflect the *y*-dimension (see also [*identity*.reflectY](#identity_reflectY)): - -```js -var reflectY = d3.geoTransform({ - point: function(x, y) { - this.stream.point(x, -y); - } -}); -``` - -Or to define an affine matrix transformation: - -```js -function matrix(a, b, c, d, tx, ty) { - return d3.geoTransform({ - point: function(x, y) { - this.stream.point(a * x + b * y + tx, c * x + d * y + ty); - } - }); -} -``` - -# d3.geoIdentity() [<>](https://github.com/d3/d3-geo/blob/master/src/projection/identity.js "Source") - -The identity transform can be used to scale, translate and clip planar geometry. It implements [*projection*.scale](#projection_scale), [*projection*.translate](#projection_translate), [*projection*.fitExtent](#projection_fitExtent), [*projection*.fitSize](#projection_fitSize), [*projection*.fitWidth](#projection_fitWidth), [*projection*.fitHeight](#projection_fitHeight), [*projection*.clipExtent](#projection_clipExtent), [*projection*.angle](#projection_angle), [*projection*.reflectX](#projection_reflectX) and [*projection*.reflectY](#projection_reflectY). - -### Clipping - -Projections perform cutting or clipping of geometries in two stages. - -# preclip(stream) - -Pre-clipping occurs in geographic coordinates. Cutting along the antimeridian line, or clipping along a small circle are the most common strategies. - -See [*projection*.preclip](#projection_preclip). - -# postclip(stream) - -Post-clipping occurs on the plane, when a projection is bounded to a certain extent such as a rectangle. - -See [*projection*.postclip](#projection_postclip). - -Clipping functions are implemented as transformations of a [projection stream](#streams). Pre-clipping operates on spherical coordinates, in radians. Post-clipping operates on planar coordinates, in pixels. - -# d3.geoClipAntimeridian - -A clipping function which transforms a stream such that geometries (lines or polygons) that cross the antimeridian line are cut in two, one on each side. Typically used for pre-clipping. - -# d3.geoClipCircle(angle) - -Generates a clipping function which transforms a stream such that geometries are bounded by a small circle of radius *angle* around the projection’s [center](#projection_center). Typically used for pre-clipping. - -# d3.geoClipRectangle(x0, y0, x1, y1) - -Generates a clipping function which transforms a stream such that geometries are bounded by a rectangle of coordinates [[x0, y0], [x1, y1]]. Typically used for post-clipping. diff --git a/node_modules/d3-geo/dist/d3-geo.js b/node_modules/d3-geo/dist/d3-geo.js deleted file mode 100644 index 3d753b2..0000000 --- a/node_modules/d3-geo/dist/d3-geo.js +++ /dev/null @@ -1,3165 +0,0 @@ -// https://d3js.org/d3-geo/ v1.12.1 Copyright 2020 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports, require('d3-array')) : -typeof define === 'function' && define.amd ? define(['exports', 'd3-array'], factory) : -(global = global || self, factory(global.d3 = global.d3 || {}, global.d3)); -}(this, (function (exports, d3Array) { 'use strict'; - -// Adds floating point numbers with twice the normal precision. -// Reference: J.

For example, the median can be computed using *p* = 0.5, the first quartile at *p* = 0.25, and the third quartile at *p* = 0.75. This particular implementation uses the [R-7 method](http://en.wikipedia.org/wiki/Quantile#Quantiles_of_a_population), which is the default for the R programming language and Excel.

If the given *array* contains no comparable elements (*i.e.*, the comparator returns NaN when comparing each element to itself), returns undefined. If *comparator* is not specified, it defaults to [ascending](#ascending).

See also [bisect](#bisect). - -# d3.bisectLeft(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js#L6 "Source") - -Returns the insertion point for *x* in *array* to maintain sorted order. The arguments *lo* and *hi* may be used to specify a subset of the array which should be considered; by default the entire array is used. If *x* is already present in *array*, the insertion point will be before (to the left of) any existing entries. The return value is suitable for use as the first argument to [splice](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/splice) assuming that *array* is already sorted. The returned insertion point *i* partitions the *array* into two halves so that all *v* < *x* for *v* in *array*.slice(*lo*, *i*) for the left side and all *v* >= *x* for *v* in *array*.slice(*i*, *hi*) for the right side. - -# d3.bisect(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js "Source")
-# d3.bisectRight(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js#L6 "Source") - -Similar to [bisectLeft](#bisectLeft), but returns an insertion point which comes after (to the right of) any existing entries of *x* in *array*. The returned insertion point *i* partitions the *array* into two halves so that all *v* <= *x* for *v* in *array*.slice(*lo*, *i*) for the left side and all *v* > *x* for *v* in *array*.slice(*i*, *hi*) for the right side. - -# d3.bisector(accessor) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js "Source") -
# d3.bisector(comparator) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js "Source") - -Returns a new bisector using the specified *accessor* or *comparator* function. This method can be used to bisect arrays of objects instead of being limited to simple arrays of primitives. For example, given the following array of objects: - -```js -var data = [ - {date: new Date(2011, 1, 1), value: 0.5}, - {date: new Date(2011, 2, 1), value: 0.6}, - {date: new Date(2011, 3, 1), value: 0.7}, - {date: new Date(2011, 4, 1), value: 0.8} -]; -``` - -A suitable bisect function could be constructed as: - -```js -var bisectDate = d3.bisector(function(d) { return d.date; }).right; -``` - -This is equivalent to specifying a comparator: - -```js -var bisectDate = d3.bisector(function(d, x) { return d.date - x; }).right; -``` - -And then applied as *bisectDate*(*array*, *date*), returning an index. Note that the comparator is always passed the search value *x* as the second argument. Use a comparator rather than an accessor if you want values to be sorted in an order different than natural order, such as in descending rather than ascending order. - -# bisector.left(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L6 "Source") - -Equivalent to [bisectLeft](#bisectLeft), but uses this bisector’s associated comparator. - -# bisector.right(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L16 "Source") - -Equivalent to [bisectRight](#bisectRight), but uses this bisector’s associated comparator. - -# d3.ascending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/ascending.js "Source") - -Returns -1 if *a* is less than *b*, or 1 if *a* is greater than *b*, or 0. This is the comparator function for natural order, and can be used in conjunction with the built-in [*array*.sort](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) method to arrange elements in ascending order. It is implemented as: - -```js -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -# d3.descending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/descending.js "Source") - -Returns -1 if *a* is greater than *b*, or 1 if *a* is less than *b*, or 0. This is the comparator function for reverse natural order, and can be used in conjunction with the built-in array sort method to arrange elements in descending order. It is implemented as: - -```js -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -### Transformations - -Methods for transforming arrays and for generating new arrays. - -# d3.cross(a, b[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/cross.js "Source") - -Returns the [Cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) of the two arrays *a* and *b*. For each element *i* in the specified array *a* and each element *j* in the specified array *b*, in order, invokes the specified *reducer* function passing the element *i* and element *j*. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.cross([1, 2], ["x", "y"]); // returns [[1, "x"], [1, "y"], [2, "x"], [2, "y"]] -d3.cross([1, 2], ["x", "y"], (a, b) => a + b); // returns ["1x", "1y", "2x", "2y"] -``` - -# d3.merge(arrays) [<>](https://github.com/d3/d3-array/blob/master/src/merge.js "Source") - -Merges the specified *arrays* into a single array. This method is similar to the built-in array concat method; the only difference is that it is more convenient when you have an array of arrays. - -```js -d3.merge([[1], [2, 3]]); // returns [1, 2, 3] -``` - -# d3.pairs(array[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/pairs.js "Source") - -For each adjacent pair of elements in the specified *array*, in order, invokes the specified *reducer* function passing the element *i* and element *i* - 1. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.pairs([1, 2, 3, 4]); // returns [[1, 2], [2, 3], [3, 4]] -d3.pairs([1, 2, 3, 4], (a, b) => b - a); // returns [1, 1, 1]; -``` - -If the specified array has fewer than two elements, returns the empty array. - -# d3.permute(array, indexes) [<>](https://github.com/d3/d3-array/blob/master/src/permute.js "Source") - -Returns a permutation of the specified *array* using the specified array of *indexes*. The returned array contains the corresponding element in array for each index in indexes, in order. For example, permute(["a", "b", "c"], [1, 2, 0]) -returns ["b", "c", "a"]. It is acceptable for the array of indexes to be a different length from the array of elements, and for indexes to be duplicated or omitted. - -This method can also be used to extract the values from an object into an array with a stable order. Extracting keyed values in order can be useful for generating data arrays in nested selections. For example: - -```js -var object = {yield: 27, variety: "Manchuria", year: 1931, site: "University Farm"}, - fields = ["site", "variety", "yield"]; - -d3.permute(object, fields); // returns ["University Farm", "Manchuria", 27] -``` - -# d3.shuffle(array[, start[, stop]]) [<>](https://github.com/d3/d3-array/blob/master/src/shuffle.js "Source") - -Randomizes the order of the specified *array* in-place using the [Fisher–Yates shuffle](https://bost.ocks.org/mike/shuffle/) and returns the *array*. If *start* is specified, it is the starting index (inclusive) of the *array* to shuffle; if *start* is not specified, it defaults to zero. If *stop* is specified, it is the ending index (exclusive) of the *array* to shuffle; if *stop* is not specified, it defaults to *array*.length. For example, to shuffle the first ten elements of the *array*: shuffle(*array*, 0, 10). - -# d3.ticks(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js "Source") - -Returns an array of approximately *count* + 1 uniformly-spaced, nicely-rounded values between *start* and *stop* (inclusive). Each value is a power of ten multiplied by 1, 2 or 5. See also [d3.tickIncrement](#tickIncrement), [d3.tickStep](#tickStep) and [*linear*.ticks](https://github.com/d3/d3-scale/blob/master/README.md#linear_ticks). - -Ticks are inclusive in the sense that they may include the specified *start* and *stop* values if (and only if) they are exact, nicely-rounded values consistent with the inferred [step](#tickStep). More formally, each returned tick *t* satisfies *start* ≤ *t* and *t* ≤ *stop*. - -# d3.tickIncrement(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Like [d3.tickStep](#tickStep), except requires that *start* is always less than or equal to *step*, and if the tick step for the given *start*, *stop* and *count* would be less than one, returns the negative inverse tick step instead. This method is always guaranteed to return an integer, and is used by [d3.ticks](#ticks) to avoid guarantee that the returned tick values are represented as precisely as possible in IEEE 754 floating point. - -# d3.tickStep(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Returns the difference between adjacent tick values if the same arguments were passed to [d3.ticks](#ticks): a nicely-rounded value that is a power of ten multiplied by 1, 2 or 5. Note that due to the limited precision of IEEE 754 floating point, the returned value may not be exact decimals; use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption. - -# d3.range([start, ]stop[, step]) [<>](https://github.com/d3/d3-array/blob/master/src/range.js "Source") - -Returns an array containing an arithmetic progression, similar to the Python built-in [range](http://docs.python.org/library/functions.html#range). This method is often used to iterate over a sequence of uniformly-spaced numeric values, such as the indexes of an array or the ticks of a linear scale. (See also [d3.ticks](#ticks) for nicely-rounded values.) - -If *step* is omitted, it defaults to 1. If *start* is omitted, it defaults to 0. The *stop* value is exclusive; it is not included in the result. If *step* is positive, the last element is the largest *start* + *i* \* *step* less than *stop*; if *step* is negative, the last element is the smallest *start* + *i* \* *step* greater than *stop*. If the returned array would contain an infinite number of values, an empty range is returned. - -The arguments are not required to be integers; however, the results are more predictable if they are. The values in the returned array are defined as *start* + *i* \* *step*, where *i* is an integer from zero to one minus the total number of elements in the returned array. For example: - -```js -d3.range(0, 1, 0.2) // [0, 0.2, 0.4, 0.6000000000000001, 0.8] -``` - -This unexpected behavior is due to IEEE 754 double-precision floating point, which defines 0.2 * 3 = 0.6000000000000001. Use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption with appropriate rounding; see also [linear.tickFormat](https://github.com/d3/d3-scale/blob/master/README.md#linear_tickFormat) in [d3-scale](https://github.com/d3/d3-scale). - -Likewise, if the returned array should have a specific length, consider using [array.map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) on an integer range. For example: - -```js -d3.range(0, 1, 1 / 49); // BAD: returns 50 elements! -d3.range(49).map(function(d) { return d / 49; }); // GOOD: returns 49 elements. -``` - -# d3.transpose(matrix) [<>](https://github.com/d3/d3-array/blob/master/src/transpose.js "Source") - -Uses the [zip](#zip) operator as a two-dimensional [matrix transpose](http://en.wikipedia.org/wiki/Transpose). - -# d3.zip(arrays…) [<>](https://github.com/d3/d3-array/blob/master/src/zip.js "Source") - -Returns an array of arrays, where the *i*th array contains the *i*th element from each of the argument *arrays*. The returned array is truncated in length to the shortest array in *arrays*. If *arrays* contains only a single array, the returned array contains one-element arrays. With no arguments, the returned array is empty. - -```js -d3.zip([1, 2], [3, 4]); // returns [[1, 3], [2, 4]] -``` - -### Histograms - -[Histogram](http://bl.ocks.org/mbostock/3048450) - -Histograms bin many discrete samples into a smaller number of consecutive, non-overlapping intervals. They are often used to visualize the distribution of numerical data. - -# d3.histogram() [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js "Source") - -Constructs a new histogram generator with the default settings. - -# histogram(data) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L14 "Source") - -Computes the histogram for the given array of *data* samples. Returns an array of bins, where each bin is an array containing the associated elements from the input *data*. Thus, the `length` of the bin is the number of elements in that bin. Each bin has two additional attributes: - -* `x0` - the lower bound of the bin (inclusive). -* `x1` - the upper bound of the bin (exclusive, except for the last bin). - -# histogram.value([value]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L58 "Source") - -If *value* is specified, sets the value accessor to the specified function or constant and returns this histogram generator. If *value* is not specified, returns the current value accessor, which defaults to the identity function. - -When a histogram is [generated](#_histogram), the value accessor will be invoked for each element in the input data array, being passed the element `d`, the index `i`, and the array `data` as three arguments. The default value accessor assumes that the input data are orderable (comparable), such as numbers or dates. If your data are not, then you should specify an accessor that returns the corresponding orderable value for a given datum. - -This is similar to mapping your data to values before invoking the histogram generator, but has the benefit that the input data remains associated with the returned bins, thereby making it easier to access other fields of the data. - -# histogram.domain([domain]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L62 "Source") - -If *domain* is specified, sets the domain accessor to the specified function or array and returns this histogram generator. If *domain* is not specified, returns the current domain accessor, which defaults to [extent](#extent). The histogram domain is defined as an array [*min*, *max*], where *min* is the minimum observable value and *max* is the maximum observable value; both values are inclusive. Any value outside of this domain will be ignored when the histogram is [generated](#_histogram). - -For example, if you are using the the histogram in conjunction with a [linear scale](https://github.com/d3/d3-scale/blob/master/README.md#linear-scales) `x`, you might say: - -```js -var histogram = d3.histogram() - .domain(x.domain()) - .thresholds(x.ticks(20)); -``` - -You can then compute the bins from an array of numbers like so: - -```js -var bins = histogram(numbers); -``` - -Note that the domain accessor is invoked on the materialized array of [values](#histogram_value), not on the input data array. - -# histogram.thresholds([count]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") -
# histogram.thresholds([thresholds]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") - -If *thresholds* is specified, sets the [threshold generator](#histogram-thresholds) to the specified function or array and returns this histogram generator. If *thresholds* is not specified, returns the current threshold generator, which by default implements [Sturges’ formula](#thresholdSturges). (Thus by default, the histogram values must be numbers!) Thresholds are defined as an array of values [*x0*, *x1*, …]. Any value less than *x0* will be placed in the first bin; any value greater than or equal to *x0* but less than *x1* will be placed in the second bin; and so on. Thus, the [generated histogram](#_histogram) will have *thresholds*.length + 1 bins. See [histogram thresholds](#histogram-thresholds) for more information. - -Any threshold values outside the [domain](#histogram_domain) are ignored. The first *bin*.x0 is always equal to the minimum domain value, and the last *bin*.x1 is always equal to the maximum domain value. - -If a *count* is specified instead of an array of *thresholds*, then the [domain](#histogram_domain) will be uniformly divided into approximately *count* bins; see [ticks](#ticks). - -### Histogram Thresholds - -These functions are typically not used directly; instead, pass them to [*histogram*.thresholds](#histogram_thresholds). You may also implement your own threshold generator taking three arguments: the array of input [*values*](#histogram_value) derived from the data, and the [observable domain](#histogram_domain) represented as *min* and *max*. The generator may then return either the array of numeric thresholds or the *count* of bins; in the latter case the domain is divided uniformly into approximately *count* bins; see [ticks](#ticks). - -# d3.thresholdFreedmanDiaconis(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/freedmanDiaconis.js "Source") - -Returns the number of bins according to the [Freedman–Diaconis rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdScott(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/scott.js "Source") - -Returns the number of bins according to [Scott’s normal reference rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdSturges(values) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/sturges.js "Source") - -Returns the number of bins according to [Sturges’ formula](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. diff --git a/node_modules/d3-geo/node_modules/d3-array/dist/d3-array.js b/node_modules/d3-geo/node_modules/d3-array/dist/d3-array.js deleted file mode 100644 index 89d17e7..0000000 --- a/node_modules/d3-geo/node_modules/d3-array/dist/d3-array.js +++ /dev/null @@ -1,590 +0,0 @@ -// https://d3js.org/d3-array/ v1.2.4 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(factory((global.d3 = global.d3 || {}))); -}(this, (function (exports) { 'use strict'; - -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} - -function bisector(compare) { - if (compare.length === 1) compare = ascendingComparator(compare); - return { - left: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) < 0) lo = mid + 1; - else hi = mid; - } - return lo; - }, - right: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) > 0) hi = mid; - else lo = mid + 1; - } - return lo; - } - }; -} - -function ascendingComparator(f) { - return function(d, x) { - return ascending(f(d), x); - }; -} - -var ascendingBisect = bisector(ascending); -var bisectRight = ascendingBisect.right; -var bisectLeft = ascendingBisect.left; - -function pairs(array, f) { - if (f == null) f = pair; - var i = 0, n = array.length - 1, p = array[0], pairs = new Array(n < 0 ? 0 : n); - while (i < n) pairs[i] = f(p, p = array[++i]); - return pairs; -} - -function pair(a, b) { - return [a, b]; -} - -function cross(values0, values1, reduce) { - var n0 = values0.length, - n1 = values1.length, - values = new Array(n0 * n1), - i0, - i1, - i, - value0; - - if (reduce == null) reduce = pair; - - for (i0 = i = 0; i0 < n0; ++i0) { - for (value0 = values0[i0], i1 = 0; i1 < n1; ++i1, ++i) { - values[i] = reduce(value0, values1[i1]); - } - } - - return values; -} - -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} - -function number(x) { - return x === null ?

[Circle-packing](#pack) tightly nests circles; this is not as space-efficient as a treemap, but perhaps more readily shows topology. - -A good hierarchical visualization facilitates rapid multiscale inference: micro-observations of individual elements and macro-observations of large groups. - -## Installing - -If you use NPM, `npm install d3-hierarchy`. Otherwise, download the [latest release](https://github.com/d3/d3-hierarchy/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-hierarchy.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -## API Reference - -* [Hierarchy](#hierarchy) ([Stratify](#stratify)) -* [Cluster](#cluster) -* [Tree](#tree) -* [Treemap](#treemap) ([Treemap Tiling](#treemap-tiling)) -* [Partition](#partition) -* [Pack](#pack) - -### Hierarchy - -Before you can compute a hierarchical layout, you need a root node. If your data is already in a hierarchical format, such as JSON, you can pass it directly to [d3.hierarchy](#hierarchy); otherwise, you can rearrange tabular data, such as comma-separated values (CSV), into a hierarchy using [d3.stratify](#stratify). - -# d3.hierarchy(data[, children]) · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/hierarchy/index.js), [Examples](https://observablehq.com/@d3/d3-hierarchy) - -Constructs a root node from the specified hierarchical *data*.

The *node*.value property of each node is set to the numeric value returned by the specified function plus the combined value of all children. The function is passed the node’s data, and must return a non-negative number.

(However, you can approximately achieve this result by generating a square treemap at different dimensions, and then [stretching the treemap](https://observablehq.com/@d3/stretched-treemap) to the desired aspect ratio.) Furthermore, the specified *ratio* is merely a hint to the tiling algorithm; the rectangles are not guaranteed to have the specified aspect ratio. If not specified, the aspect ratio defaults to the golden ratio, φ = (1 + sqrt(5)) / 2, per [Kong *et al.*](http://vis.stanford.edu/papers/perception-treemaps) - -### Partition - -[Partition](https://observablehq.com/@d3/icicle) - -The **partition layout** produces adjacency diagrams: a space-filling variant of a node-link tree diagram. Rather than drawing a link between parent and child in the hierarchy, nodes are drawn as solid areas (either arcs or rectangles), and their placement relative to other nodes reveals their position in the hierarchy.

The size of the leaf circles encodes a quantitative dimension of the data. The enclosing circles show the approximate cumulative size of each subtree, but due to wasted space there is some distortion; only the leaf nodes can be compared accurately. Although [circle packing](http://en.wikipedia.org/wiki/Circle_packing) does not use space as efficiently as a [treemap](#treemap), the “wasted” space more prominently reveals the hierarchical structure. - -# d3.pack() · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/pack/index.js), [Examples](https://observablehq.com/@d3/circle-packing) - -Creates a new pack layout with the default settings. - -# pack(root) - -Lays out the specified *root* [hierarchy](#hierarchy), assigning the following properties on *root* and its descendants: - -* *node*.x - the *x*-coordinate of the circle’s center -* *node*.y - the *y*-coordinate of the circle’s center -* *node*.r - the radius of the circle - -You must call [*root*.sum](#node_sum) before passing the hierarchy to the pack layout.

If the radius accessor is null, the radius of each leaf circle is derived from the leaf *node*.value (computed by [*node*.sum](#node_sum)); the radii are then scaled proportionally to fit the [layout size](#pack_size). If the radius accessor is not null, the radius of each leaf circle is specified exactly by the function. - -# pack.size([size]) - -If *size* is specified, sets this pack layout’s size to the specified two-element array of numbers [*width*, *height*] and returns this pack layout.

When siblings are packed, tangent siblings will be separated by approximately the specified padding; the enclosing parent circle will also be separated from its children by approximately the specified padding. If an [explicit radius](#pack_radius) is not specified, the padding is approximate because a two-pass algorithm is needed to fit within the [layout size](#pack_size): the circles are first packed without padding; a scaling factor is computed and applied to the specified padding; and lastly the circles are re-packed with padding. - -# d3.packSiblings(circles) · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/pack/siblings.js) - -Packs the specified array of *circles*, each of which must have a *circle*.r property specifying the circle’s radius.

All [nodes](#nodes) in the returned quadtree are identical copies of the corresponding node in the quadtree; however, any data in the quadtree is shared by reference and not copied. - -# quadtree.root() - [<>](https://github.com/d3/d3-quadtree/blob/master/src/root.js "Source") - -Returns the root [node](#nodes) of the quadtree. - -# quadtree.data() - [<>](https://github.com/d3/d3-quadtree/blob/master/src/data.js "Source") - -Returns an array of all data in the quadtree. - -# quadtree.size() - [<>](https://github.com/d3/d3-quadtree/blob/master/src/size.js "Source") - -Returns the total number of data in the quadtree. - -# quadtree.find(x, y[, radius]) - [<>](https://github.com/d3/d3-quadtree/blob/master/src/find.js "Source") - -Returns the datum closest to the position ⟨*x*,*y*⟩ with the given search *radius*. If *radius* is not specified, it defaults to infinity. If there is no datum within the search area, returns undefined. - -# quadtree.visit(callback) - [<>](https://github.com/d3/d3-quadtree/blob/master/src/visit.js "Source") - -Visits each [node](#nodes) in the quadtree in pre-order traversal, invoking the specified *callback* with arguments *node*, *x0*, *y0*, *x1*, *y1* for each node, where *node* is the node being visited, ⟨*x0*, *y0*⟩ are the lower bounds of the node, and ⟨*x1*, *y1*⟩ are the upper bounds, and returns the quadtree. (Assuming that positive *x* is right and positive *y* is down, as is typically the case in Canvas and SVG, ⟨*x0*, *y0*⟩ is the top-left corner and ⟨*x1*, *y1*⟩ is the lower-right corner; however, the coordinate system is arbitrary, so more formally *x0* <= *x1* and *y0* <= *y1*.) - -If the *callback* returns true for a given node, then the children of that node are not visited; otherwise, all child nodes are visited. This can be used to quickly visit only parts of the tree, for example when using the [Barnes–Hut approximation](https://en.wikipedia.org/wiki/Barnes–Hut_simulation). Note, however, that child quadrants are always visited in sibling order: top-left, top-right, bottom-left, bottom-right. In cases such as [search](#quadtree_find), visiting siblings in a specific order may be faster. - -# quadtree.visitAfter(callback) - [<>](https://github.com/d3/d3-quadtree/blob/master/src/visitAfter.js "Source") - -Visits each [node](#nodes) in the quadtree in post-order traversal, invoking the specified *callback* with arguments *node*, *x0*, *y0*, *x1*, *y1* for each node, where *node* is the node being visited, ⟨*x0*, *y0*⟩ are the lower bounds of the node, and ⟨*x1*, *y1*⟩ are the upper bounds, and returns the quadtree. (Assuming that positive *x* is right and positive *y* is down, as is typically the case in Canvas and SVG, ⟨*x0*, *y0*⟩ is the top-left corner and ⟨*x1*, *y1*⟩ is the lower-right corner; however, the coordinate system is arbitrary, so more formally *x0* <= *x1* and *y0* <= *y1*.) Returns *root*. - -### Nodes - -Internal nodes of the quadtree are represented as four-element arrays in left-to-right, top-to-bottom order: - -* `0` - the top-left quadrant, if any. -* `1` - the top-right quadrant, if any. -* `2` - the bottom-left quadrant, if any. -* `3` - the bottom-right quadrant, if any. - -A child quadrant may be undefined if it is empty. - -Leaf nodes are represented as objects with the following properties: - -* `data` - the data associated with this point, as passed to [*quadtree*.add](#quadtree_add). -* `next` - the next datum in this leaf, if any. - -The `length` property may be used to distinguish leaf nodes from internal nodes: it is undefined for leaf nodes, and 4 for internal nodes. For example, to iterate over all data in a leaf node: - -```js -if (!node.length) do console.log(node.data); while (node = node.next); -``` - -The point’s *x*- and *y*-coordinates **must not be modified** while the point is in the quadtree. To update a point’s position, [remove](#quadtree_remove) the point and then re-[add](#quadtree_add) it to the quadtree at the new position. Alternatively, you may discard the existing quadtree entirely and create a new one from scratch; this may be more efficient if many of the points have moved. diff --git a/node_modules/d3-quadtree/dist/d3-quadtree.js b/node_modules/d3-quadtree/dist/d3-quadtree.js deleted file mode 100644 index 02b9a00..0000000 --- a/node_modules/d3-quadtree/dist/d3-quadtree.js +++ /dev/null @@ -1,419 +0,0 @@ -// https://d3js.org/d3-quadtree/ v1.0.7 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ?

A [quantize scale](#quantize-scales) may aid differentiation by rounding continuous data to a fixed set of discrete values; similarly, a [quantile scale](#quantile-scales) computes quantiles from a sample population, and a [threshold scale](#threshold-scales) allows you to specify arbitrary breaks in continuous data. - -For discrete ordinal (ordered) or categorical (unordered) data, an [ordinal scale](#ordinal-scales) specifies an explicit mapping from a set of data values to a corresponding set of visual attributes (such as colors). The related [band](#band-scales) and [point](#point-scales) scales are useful for position-encoding ordinal data, such as bars in a bar chart or dots in an categorical scatterplot. - -This repository does not provide color schemes; see [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic) for color schemes designed to work with d3-scale. - -Scales have no intrinsic visual representation. However, most scales can [generate](#continuous_ticks) and [format](#continuous_tickFormat) ticks for reference marks to aid in the construction of axes. - -For a longer introduction, see these recommended tutorials: - -* [Introducing d3-scale](https://medium.com/@mbostock/introducing-d3-scale-61980c51545f) by Mike Bostock - -* Chapter 7.

In vanilla, a `d3` global is exported: - -```html - - - - - - - - -``` - -(You can omit d3-time and d3-time-format if you’re not using [d3.scaleTime](#scaleTime) or [d3.scaleUtc](#scaleUtc).) - -## API Reference - -* [Continuous](#continuous-scales) ([Linear](#linear-scales), [Power](#power-scales), [Log](#log-scales), [Identity](#identity-scales), [Time](#time-scales), [Radial](#radial-scales)) -* [Sequential](#sequential-scales) -* [Diverging](#diverging-scales) -* [Quantize](#quantize-scales) -* [Quantile](#quantile-scales) -* [Threshold](#threshold-scales) -* [Ordinal](#ordinal-scales) ([Band](#band-scales), [Point](#point-scales)) - -### Continuous Scales - -Continuous scales map a continuous, quantitative input [domain](#continuous_domain) to a continuous output [range](#continuous_range). If the range is also numeric, the mapping may be [inverted](#continuous_invert). A continuous scale is not constructed directly; instead, try a [linear](#linear-scales), [power](#power-scales), [log](#log-scales), [identity](#identity-scales), [radial](#radial-scales), [time](#time-scales) or [sequential color](#sequential-scales) scale. - -# continuous(value) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -Given a *value* from the [domain](#continuous_domain), returns the corresponding value from the [range](#continuous_range). If the given *value* is outside the domain, and [clamping](#continuous_clamp) is not enabled, the mapping may be extrapolated such that the returned value is outside the range. For example, to apply a position encoding: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x(20); // 80 -x(50); // 320 -``` - -Or to apply a color encoding: - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]); - -color(20); // "#9a3439" -color(50); // "#7b5167" -``` - -Or, in shorthand: - -```js -var x = d3.scaleLinear([10, 130], [0, 960]); -var color = d3.scaleLinear([10, 100], ["brown", "steelblue"]); -``` - -# continuous.invert(value) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -Given a *value* from the [range](#continuous_range), returns the corresponding value from the [domain](#continuous_domain). Inversion is useful for interaction, say to determine the data value corresponding to the position of the mouse. For example, to invert a position encoding: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x.invert(80); // 20 -x.invert(320); // 50 -``` - -If the given *value* is outside the range, and [clamping](#continuous_clamp) is not enabled, the mapping may be extrapolated such that the returned value is outside the domain. This method is only supported if the range is numeric. If the range is not numeric, returns NaN. - -For a valid value *y* in the range, continuous(continuous.invert(y)) approximately equals *y*; similarly, for a valid value *x* in the domain, continuous.invert(continuous(x)) approximately equals *x*. The scale and its inverse may not be exact due to the limitations of floating point precision. - -# continuous.domain([domain]) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -If *domain* is specified, sets the scale’s domain to the specified array of numbers. The array must contain two or more elements. If the elements in the given array are not numbers, they will be coerced to numbers. If *domain* is not specified, returns a copy of the scale’s current domain. - -Although continuous scales typically have two values each in their domain and range, specifying more than two values produces a piecewise scale. For example, to create a [diverging color scale](#diverging-scales) that interpolates between white and red for negative values, and white and green for positive values, say: - -```js -var color = d3.scaleLinear() - .domain([-1, 0, 1]) - .range(["red", "white", "green"]); - -color(-0.5); // "rgb(255, 128, 128)" -color(+0.5); // "rgb(128, 192, 128)" -``` - -Internally, a piecewise scale performs a [binary search](https://github.com/d3/d3-array/blob/master/README.md#bisect) for the range interpolator corresponding to the given domain value. Thus, the domain must be in ascending or descending order. If the domain and range have different lengths *N* and *M*, only the first *min(N,M)* elements in each are observed. - -# continuous.range([range]) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -If *range* is specified, sets the scale’s range to the specified array of values. The array must contain two or more elements. Unlike the [domain](#continuous_domain), elements in the given array need not be numbers; any value that is supported by the underlying [interpolator](#continuous_interpolate) will work, though note that numeric ranges are required for [invert](#continuous_invert). If *range* is not specified, returns a copy of the scale’s current range. See [*continuous*.interpolate](#continuous_interpolate) for more examples. - -# continuous.rangeRound([range]) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -Sets the scale’s [*range*](#continuous_range) to the specified array of values while also setting the scale’s [interpolator](#continuous_interpolate) to [interpolateRound](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateRound). This is a convenience method equivalent to: - -```js -continuous - .range(range) - .interpolate(d3.interpolateRound); -``` - -The rounding interpolator is sometimes useful for avoiding antialiasing artifacts, though also consider the [shape-rendering](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/shape-rendering) “crispEdges” styles. Note that this interpolator can only be used with numeric ranges. - -# continuous.clamp(clamp) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -If *clamp* is specified, enables or disables clamping accordingly. If clamping is disabled and the scale is passed a value outside the [domain](#continuous_domain), the scale may return a value outside the [range](#continuous_range) through extrapolation. If clamping is enabled, the return value of the scale is always within the scale’s range. Clamping similarly applies to [*continuous*.invert](#continuous_invert). For example: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x(-10); // -160, outside range -x.invert(-160); // -10, outside domain - -x.clamp(true); -x(-10); // 0, clamped to range -x.invert(-160); // 10, clamped to domain -``` - -If *clamp* is not specified, returns whether or not the scale currently clamps values to within the range. - -# continuous.unknown([value]) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -If *value* is specified, sets the output value of the scale for undefined (or NaN) input values and returns this scale. If *value* is not specified, returns the current unknown value, which defaults to undefined. - -# continuous.interpolate(interpolate) · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -If *interpolate* is specified, sets the scale’s [range](#continuous_range) interpolator factory. This interpolator factory is used to create interpolators for each adjacent pair of values from the range; these interpolators then map a normalized domain parameter *t* in [0, 1] to the corresponding value in the range. If *factory* is not specified, returns the scale’s current interpolator factory, which defaults to [d3.interpolate](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate). See [d3-interpolate](https://github.com/d3/d3-interpolate) for more interpolators. - -For example, consider a diverging color scale with three colors in the range: - -```js -var color = d3.scaleLinear() - .domain([-100, 0, +100]) - .range(["red", "white", "green"]); -``` - -Two interpolators are created internally by the scale, equivalent to: - -```js -var i0 = d3.interpolate("red", "white"), - i1 = d3.interpolate("white", "green"); -``` - -A common reason to specify a custom interpolator is to change the color space of interpolation. For example, to use [HCL](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateHcl): - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]) - .interpolate(d3.interpolateHcl); -``` - -Or for [Cubehelix](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateCubehelix) with a custom gamma: - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]) - .interpolate(d3.interpolateCubehelix.gamma(3)); -``` - -Note: the [default interpolator](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate) **may reuse return values**. For example, if the range values are objects, then the value interpolator always returns the same object, modifying it in-place. If the scale is used to set an attribute or style, this is typically acceptable (and desirable for performance); however, if you need to store the scale’s return value, you must specify your own interpolator or make a copy as appropriate. - -# continuous.ticks([count]) - -Returns approximately *count* representative values from the scale’s [domain](#continuous_domain). If *count* is not specified, it defaults to 10. The returned tick values are uniformly spaced, have human-readable values (such as multiples of powers of 10), and are guaranteed to be within the extent of the domain. Ticks are often used to display reference lines, or tick marks, in conjunction with the visualized data. The specified *count* is only a hint; the scale may return more or fewer values depending on the domain. See also d3-array’s [ticks](https://github.com/d3/d3-array/blob/master/README.md#ticks). - -# continuous.tickFormat([count[, specifier]]) · [Source](https://github.com/d3/d3-scale/blob/master/src/tickFormat.js), [Examples](https://observablehq.com/@d3/scale-ticks) - -Returns a [number format](https://github.com/d3/d3-format) function suitable for displaying a tick value, automatically computing the appropriate precision based on the fixed interval between tick values. The specified *count* should have the same value as the count that is used to generate the [tick values](#continuous_ticks). - -An optional *specifier* allows a [custom format](https://github.com/d3/d3-format/blob/master/README.md#locale_format) where the precision of the format is automatically set by the scale as appropriate for the tick interval. For example, to format percentage change, you might say: - -```js -var x = d3.scaleLinear() - .domain([-1, 1]) - .range([0, 960]); - -var ticks = x.ticks(5), - tickFormat = x.tickFormat(5, "+%"); - -ticks.map(tickFormat); // ["-100%", "-50%", "+0%", "+50%", "+100%"] -``` - -If *specifier* uses the format type `s`, the scale will return a [SI-prefix format](https://github.com/d3/d3-format/blob/master/README.md#locale_formatPrefix) based on the largest value in the domain. If the *specifier* already specifies a precision, this method is equivalent to [*locale*.format](https://github.com/d3/d3-format/blob/master/README.md#locale_format). - -See also [d3.tickFormat](#tickFormat). - -# continuous.nice([count]) · [Source](https://github.com/d3/d3-scale/blob/master/src/nice.js), [Examples](https://observablehq.com/@d3/d3-scalelinear) - -Extends the [domain](#continuous_domain) so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. An optional tick *count* argument allows greater control over the step size used to extend the bounds, guaranteeing that the returned [ticks](#continuous_ticks) will exactly cover the domain. Nicing is useful if the domain is computed from data, say using [extent](https://github.com/d3/d3-array/blob/master/README.md#extent), and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0]. If the domain has more than two values, nicing the domain only affects the first and last value. See also d3-array’s [tickStep](https://github.com/d3/d3-array/blob/master/README.md#tickStep). - -Nicing a scale only modifies the current domain; it does not automatically nice domains that are subsequently set using [*continuous*.domain](#continuous_domain). You must re-nice the scale after setting the new domain, if desired. - -# continuous.copy() · [Source](https://github.com/d3/d3-scale/blob/master/src/continuous.js), [Examples](https://observablehq.com/@d3/continuous-scales) - -Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa. - -# d3.tickFormat(start, stop, count[, specifier]) · [Source](https://github.com/d3/d3-scale/blob/master/src/tickFormat.js), [Examples](https://observablehq.com/@d3/scale-ticks) - -Returns a [number format](https://github.com/d3/d3-format) function suitable for displaying a tick value, automatically computing the appropriate precision based on the fixed interval between tick values, as determined by [d3.tickStep](https://github.com/d3/d3-array/blob/master/README.md#tickStep). - -An optional *specifier* allows a [custom format](https://github.com/d3/d3-format/blob/master/README.md#locale_format) where the precision of the format is automatically set by the scale as appropriate for the tick interval. For example, to format percentage change, you might say: - -```js -var tickFormat = d3.tickFormat(-1, 1, 5, "+%"); - -tickFormat(-0.5); // "-50%" -``` - -If *specifier* uses the format type `s`, the scale will return a [SI-prefix format](https://github.com/d3/d3-format/blob/master/README.md#locale_formatPrefix) based on the larger absolute value of *start* and *stop*. If the *specifier* already specifies a precision, this method is equivalent to [*locale*.format](https://github.com/d3/d3-format/blob/master/README.md#locale_format). - -#### Linear Scales - -# d3.scaleLinear([[domain, ]range]) · [Source](https://github.com/d3/d3-scale/blob/master/src/linear.js), [Examples](https://observablehq.com/@d3/d3-scalelinear) - -Constructs a new [continuous scale](#continuous-scales) with the specified [domain](#continuous_domain) and [range](#continuous_range), the [default](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate) [interpolator](#continuous_interpolate) and [clamping](#continuous_clamp) disabled. If either *domain* or *range* are not specified, each defaults to [0, 1]. Linear scales are a good default choice for continuous quantitative data because they preserve proportional differences. Each range value *y* can be expressed as a function of the domain value *x*: *y* = *mx* + *b*. - -#### Power Scales - -Power scales are similar to [linear scales](#linear-scales), except an exponential transform is applied to the input domain value before the output range value is computed. Each range value *y* can be expressed as a function of the domain value *x*: *y* = *mx^k* + *b*, where *k* is the [exponent](#pow_exponent) value.

If *domain* or *range* is not specified, each defaults to [0, 1]. - -#### Time Scales - -Time scales are a variant of [linear scales](#linear-scales) that have a temporal domain: domain values are coerced to [dates](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date) rather than numbers, and [invert](#continuous_invert) likewise returns a date. Time scales implement [ticks](#time_ticks) based on [calendar intervals](https://github.com/d3/d3-time), taking the pain out of generating axes for temporal domains. - -For example, to create a position encoding: - -```js -var x = d3.scaleTime() - .domain([new Date(2000, 0, 1), new Date(2000, 0, 2)]) - .range([0, 960]); - -x(new Date(2000, 0, 1, 5)); // 200 -x(new Date(2000, 0, 1, 16)); // 640 -x.invert(200); // Sat Jan 01 2000 05:00:00 GMT-0800 (PST) -x.invert(640); // Sat Jan 01 2000 16:00:00 GMT-0800 (PST) -``` - -For a valid value *y* in the range, time(time.invert(y)) equals *y*; similarly, for a valid value *x* in the domain, time.invert(time(x)) equals *x*. The invert method is useful for interaction, say to determine the value in the domain that corresponds to the pixel location under the mouse. - -# d3.scaleTime([[domain, ]range]) · [Source](https://github.com/d3/d3-scale/blob/master/src/time.js), [Examples](https://observablehq.com/@d3/d3-scaletime) - -Constructs a new time scale with the specified [domain](#time_domain) and [range](#time_range), the [default](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate) [interpolator](#time_interpolate) and [clamping](#time_clamp) disabled.

# time.ticks([interval]) - -Returns representative dates from the scale’s [domain](#time_domain). The returned tick values are uniformly-spaced (mostly), have sensible values (such as every day at midnight), and are guaranteed to be within the extent of the domain. Ticks are often used to display reference lines, or tick marks, in conjunction with the visualized data. - -An optional *count* may be specified to affect how many ticks are generated. If *count* is not specified, it defaults to 10. The specified *count* is only a hint; the scale may return more or fewer values depending on the domain. For example, to create ten default ticks, say: - -```js -var x = d3.scaleTime(); - -x.ticks(10); -// [Sat Jan 01 2000 00:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 03:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 06:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 09:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 12:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 15:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 18:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 21:00:00 GMT-0800 (PST), -// Sun Jan 02 2000 00:00:00 GMT-0800 (PST)] -``` - -The following time intervals are considered for automatic ticks: - -* 1-, 5-, 15- and 30-second. -* 1-, 5-, 15- and 30-minute. -* 1-, 3-, 6- and 12-hour. -* 1- and 2-day. -* 1-week. -* 1- and 3-month. -* 1-year. - -In lieu of a *count*, a [time *interval*](https://github.com/d3/d3-time/blob/master/README.md#intervals) may be explicitly specified. To prune the generated ticks for a given time *interval*, use [*interval*.every](https://github.com/d3/d3-time/blob/master/README.md#interval_every). For example, to generate ticks at 15-[minute](https://github.com/d3/d3-time/blob/master/README.md#minute) intervals: - -```js -var x = d3.scaleTime() - .domain([new Date(2000, 0, 1, 0), new Date(2000, 0, 1, 2)]); - -x.ticks(d3.timeMinute.every(15)); -// [Sat Jan 01 2000 00:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:15:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:30:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:45:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:15:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:30:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:45:00 GMT-0800 (PST), -// Sat Jan 01 2000 02:00:00 GMT-0800 (PST)] -``` - -Alternatively, pass a test function to [*interval*.filter](https://github.com/d3/d3-time/blob/master/README.md#interval_filter): - -```js -x.ticks(d3.timeMinute.filter(function(d) { - return d.getMinutes() % 15 === 0; -})); -``` - -Note: in some cases, such as with day ticks, specifying a *step* can result in irregular spacing of ticks because time intervals have varying length. - -# time.tickFormat([count[, specifier]]) · [Source](https://github.com/d3/d3-scale/blob/master/src/time.js), [Examples](https://observablehq.com/@d3/scale-ticks) -
# time.tickFormat([interval[, specifier]]) - -Returns a time format function suitable for displaying [tick](#time_ticks) values. The specified *count* or *interval* is currently ignored, but is accepted for consistency with other scales such as [*continuous*.tickFormat](#continuous_tickFormat). If a format *specifier* is specified, this method is equivalent to [format](https://github.com/d3/d3-time-format/blob/master/README.md#format). If *specifier* is not specified, the default time format is returned. The default multi-scale time format chooses a human-readable representation based on the specified date as follows: - -* `%Y` - for year boundaries, such as `2011`. -* `%B` - for month boundaries, such as `February`. -* `%b %d` - for week boundaries, such as `Feb 06`. -* `%a %d` - for day boundaries, such as `Mon 07`. -* `%I %p` - for hour boundaries, such as `01 AM`. -* `%I:%M` - for minute boundaries, such as `01:23`. -* `:%S` - for second boundaries, such as `:45`. -* `.%L` - milliseconds for all other times, such as `.012`. - -Although somewhat unusual, this default behavior has the benefit of providing both local and global context: for example, formatting a sequence of ticks as [11 PM, Mon 07, 01 AM] reveals information about hours, dates, and day simultaneously, rather than just the hours [11 PM, 12 AM, 01 AM]. See [d3-time-format](https://github.com/d3/d3-time-format) if you’d like to roll your own conditional time format. - -# time.nice([count]) · [Source](https://github.com/d3/d3-scale/blob/master/src/time.js), [Examples](https://observablehq.com/@d3/d3-scaletime) -
# time.nice([interval]) - -Extends the [domain](#time_domain) so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. See [*continuous*.nice](#continuous_nice) for more. - -An optional tick *count* argument allows greater control over the step size used to extend the bounds, guaranteeing that the returned [ticks](#time_ticks) will exactly cover the domain. Alternatively, a [time *interval*](https://github.com/d3/d3-time/blob/master/README.md#intervals) may be specified to explicitly set the ticks. If an *interval* is specified, an optional *step* may also be specified to skip some ticks. For example, `time.nice(d3.timeSecond.every(10))` will extend the domain to an even ten seconds (0, 10, 20, etc.). See [*time*.ticks](#time_ticks) and [*interval*.every](https://github.com/d3/d3-time/blob/master/README.md#interval_every) for further detail. - -Nicing is useful if the domain is computed from data, say using [extent](https://github.com/d3/d3-array/blob/master/README.md#extent), and may be irregular. For example, for a domain of [2009-07-13T00:02, 2009-07-13T23:48], the nice domain is [2009-07-13, 2009-07-14]. If the domain has more than two values, nicing the domain only affects the first and last value. - -# d3.scaleUtc([[domain, ]range]) · [Source](https://github.com/d3/d3-scale/blob/master/src/utcTime.js), [Examples](https://observablehq.com/@d3/d3-scaletime) - -Equivalent to [scaleTime](#scaleTime), but the returned time scale operates in [Coordinated Universal Time](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) rather than local time. - -### Sequential Scales - -Sequential scales, like [diverging scales](#diverging-scales), are similar to [continuous scales](#continuous-scales) in that they map a continuous, numeric input domain to a continuous output range. However, unlike continuous scales, the input domain and output range of a sequential scale always has exactly two elements, and the output range is typically specified as an interpolator rather than an array of values. These scales do not expose [invert](#continuous_invert) and [interpolate](#continuous_interpolate) methods. - -# d3.scaleSequential([[domain, ]interpolator]) · [Source](https://github.com/d3/d3-scale/blob/master/src/sequential.js), [Examples](https://observablehq.com/@d3/sequential-scales) - -Constructs a new sequential scale with the specified [*domain*](#sequential_domain) and [*interpolator*](#sequential_interpolator) function. If *domain* is not specified, it defaults to [0, 1]. If *interpolator* is not specified, it defaults to the identity function. When the scale is [applied](#_sequential), the interpolator will be invoked with a value typically in the range [0, 1], where 0 represents the minimum value and 1 represents the maximum value.

For example, a bar chart of monthly sales might be broken down into a multi-series bar chart by product category, stacking bars vertically. This is equivalent to subdividing a bar chart by an ordinal dimension (such as product category) and applying a color encoding. - -Stacked charts can show overall value and per-category value simultaneously; however, it is typically harder to compare across categories, as only the bottom layer of the stack is aligned. So, chose the [stack order](#stack_order) carefully, and consider a [streamgraph](#stackOffsetWiggle). (See also [grouped charts](https://observablehq.com/@d3/grouped-bar-chart).) - -Like the [pie generator](#pies), the stack generator does not produce a shape directly.

Any additional *arguments* are arbitrary; they are simply propagated to accessors along with the `this` object. - -The series are determined by the [keys accessor](#stack_keys); each series *i* in the returned array corresponds to the *i*th key. Each series is an array of points, where each point *j* corresponds to the *j*th element in the input *data*. Lastly, each point is represented as an array [*y0*, *y1*] where *y0* is the lower value (baseline) and *y1* is the upper value (topline); the difference between *y0* and *y1* corresponds to the computed [value](#stack_value) for this point. The key for each series is available as *series*.key, and the [index](#stack_order) as *series*.index. The input data element for each point is available as *point*.data. - -For example, consider the following table representing monthly sales of fruits: - -Month | Apples | Bananas | Cherries | Dates ---------|--------|---------|----------|------- - 1/2015 | 3840 | 1920 | 960 | 400 - 2/2015 | 1600 | 1440 | 960 | 400 - 3/2015 | 640 | 960 | 640 | 400 - 4/2015 | 320 | 480 | 640 | 400 - -This might be represented in JavaScript as an array of objects: - -```js -var data = [ - {month: new Date(2015, 0, 1), apples: 3840, bananas: 1920, cherries: 960, dates: 400}, - {month: new Date(2015, 1, 1), apples: 1600, bananas: 1440, cherries: 960, dates: 400}, - {month: new Date(2015, 2, 1), apples: 640, bananas: 960, cherries: 640, dates: 400}, - {month: new Date(2015, 3, 1), apples: 320, bananas: 480, cherries: 640, dates: 400} -]; -``` - -To produce a stack for this data: - -```js -var stack = d3.stack() - .keys(["apples", "bananas", "cherries", "dates"]) - .order(d3.stackOrderNone) - .offset(d3.stackOffsetNone); - -var series = stack(data); -``` - -The resulting array has one element per *series*. Each series has one point per month, and each point has a lower and upper value defining the baseline and topline: - -```js -[ - [[ 0, 3840], [ 0, 1600], [ 0, 640], [ 0, 320]], // apples - [[3840, 5760], [1600, 3040], [ 640, 1600], [ 320, 800]], // bananas - [[5760, 6720], [3040, 4000], [1600, 2240], [ 800, 1440]], // cherries - [[6720, 7120], [4000, 4400], [2240, 2640], [1440, 1840]], // dates -] -``` - -Each series in then typically passed to an [area generator](#areas) to render an area chart, or used to construct rectangles for a bar chart. - -# stack.keys([keys]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *keys* is specified, sets the keys accessor to the specified function or array and returns this stack generator. If *keys* is not specified, returns the current keys accessor, which defaults to the empty array. A series (layer) is [generated](#_stack) for each key. Keys are typically strings, but they may be arbitrary values. The series’ key is passed to the [value accessor](#stack_value), along with each data point, to compute the point’s value. - -# stack.value([value]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *value* is specified, sets the value accessor to the specified function or number and returns this stack generator. If *value* is not specified, returns the current value accessor, which defaults to: - -```js -function value(d, key) { - return d[key]; -} -``` - -Thus, by default the stack generator assumes that the input data is an array of objects, with each object exposing named properties with numeric values; see [*stack*](#_stack) for an example. - -# stack.order([order]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *order* is specified, sets the order accessor to the specified function or array and returns this stack generator.

See [stack orders](#stack-orders) for the built-in orders. - -If *order* is a function, it is passed the generated series array and must return an array of numeric indexes representing the stack order. For example, the default order is defined as: - -```js -function orderNone(series) { - var n = series.length, o = new Array(n); - while (--n >= 0) o[n] = n; - return o; -} -``` - -The stack order is computed prior to the [offset](#stack_offset); thus, the lower value for all points is zero at the time the order is computed. The index attribute for each series is also not set until after the order is computed. - -# stack.offset([offset]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *offset* is specified, sets the offset accessor to the specified function or array and returns this stack generator. If *offset* is not specified, returns the current offset acccesor, which defaults to [stackOffsetNone](#stackOffsetNone); this uses a zero baseline. See [stack offsets](#stack-offsets) for the built-in offsets. - -If *offset* is a function, it is passed the generated series array and the order index array. The offset function is then responsible for updating the lower and upper values in the series array to layout the stack. For example, the default offset is defined as: - -```js -function offsetNone(series, order) { - if (!((n = series.length) > 1)) return; - for (var i = 1, s0, s1 = series[order[0]], n, m = s1.length; i < n; ++i) { - s0 = s1, s1 = series[order[i]]; - for (var j = 0; j < m; ++j) { - s1[j][1] += s1[j][0] = s0[j][1]; - } - } -} -``` - -### Stack Orders - -Stack orders are typically not used directly, but are instead passed to [*stack*.order](#stack_order). - -# d3.stackOrderAppearance(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/appearance.js) - -Returns a series order such that the earliest series (according to the maximum value) is at the bottom. - -# d3.stackOrderAscending(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/ascending.js) - -Returns a series order such that the smallest series (according to the sum of values) is at the bottom. - -# d3.stackOrderDescending(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/descending.js) - -Returns a series order such that the largest series (according to the sum of values) is at the bottom. - -# d3.stackOrderInsideOut(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/insideOut.js) - -Returns a series order such that the earliest series (according to the maximum value) are on the inside and the later series are on the outside.

In the [Gregorian calendar](https://en.wikipedia.org/wiki/Gregorian_calendar), for example, most months have 31 days but some have 28, 29 or 30; most years have 365 days but [leap years](https://en.wikipedia.org/wiki/Leap_year) have 366; and with [daylight saving](https://en.wikipedia.org/wiki/Daylight_saving_time), most days have 24 hours but some have 23 or 25. Adding to complexity, daylight saving conventions vary around the world. - -As a result of these temporal peculiarities, it can be difficult to perform seemingly-trivial tasks. For example, if you want to compute the number of days that have passed between two dates, you can’t simply subtract and divide by 24 hours (86,400,000 ms): - -```js -var start = new Date(2015, 02, 01), // Sun Mar 01 2015 00:00:00 GMT-0800 (PST) - end = new Date(2015, 03, 01); // Wed Apr 01 2015 00:00:00 GMT-0700 (PDT) -(end - start) / 864e5; // 30.958333333333332, oops! -``` - -You can, however, use [d3.timeDay](#timeDay).[count](#interval_count): - -```js -d3.timeDay.count(start, end); // 31 -``` - -The [day](#day) [interval](#api-reference) is one of several provided by d3-time. Each interval represents a conventional unit of time—[hours](#timeHour), [weeks](#timeWeek), [months](#timeMonth), *etc.*—and has methods to calculate boundary dates. For example, [d3.timeDay](#timeDay) computes midnight (typically 12:00 AM local time) of the corresponding day. In addition to [rounding](#interval_round) and [counting](#interval_count), intervals can also be used to generate arrays of boundary dates. For example, to compute each Sunday in the current month: - -```js -var now = new Date; -d3.timeWeek.range(d3.timeMonth.floor(now), d3.timeMonth.ceil(now)); -// [Sun Jun 07 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 14 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 21 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 28 2015 00:00:00 GMT-0700 (PDT)] -``` - -The d3-time module does not implement its own calendaring system; it merely implements a convenient API for calendar math on top of ECMAScript [Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date). Thus, it ignores leap seconds and can only work with the local time zone and [Coordinated Universal Time](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) (UTC). - -This module is used by D3’s time scales to generate sensible ticks, by D3’s time format, and can also be used directly to do things like [calendar layouts](http://bl.ocks.org/mbostock/4063318). - -## Installing - -If you use NPM, `npm install d3-time`. Otherwise, download the [latest release](https://github.com/d3/d3-time/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-time.v1.min.js) or as part of [D3 4.0](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -[Try d3-time in your browser.](https://tonicdev.com/npm/d3-time) - -## API Reference - -# interval([date]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L6 "Source") - -Equivalent to [*interval*.floor](#interval_floor), except it *date* is not specified, it defaults to the current time. For example, [d3.timeYear](#timeYear)(*date*) and d3.timeYear.floor(*date*) are equivalent. - -```js -var monday = d3.timeMonday(); // The latest preceeding Monday, local time. -``` - -# interval.floor(date) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L10 "Source") - -Returns a new date representing the latest interval boundary date before or equal to *date*. For example, [d3.timeDay](#timeDay).floor(*date*) typically returns 12:00 AM local time on the given *date*. - -This method is idempotent: if the specified *date* is already floored to the current interval, a new date with an identical time is returned. Furthermore, the returned date is the minimum expressible value of the associated interval, such that *interval*.floor(*interval*.floor(*date*) - 1) returns the preceeding interval boundary date. - -Note that the `==` and `===` operators do not compare by value with [Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) objects, and thus you cannot use them to tell whether the specified *date* has already been floored. Instead, coerce to a number and then compare: - -```js -// Returns true if the specified date is a day boundary. -function isDay(date) { - return +d3.timeDay.floor(date) === +date; -} -``` - -This is more reliable than testing whether the time is 12:00 AM, as in some time zones midnight may not exist due to daylight saving. - -# interval.round(date) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L16 "Source") - -Returns a new date representing the closest interval boundary date to *date*. For example, [d3.timeDay](#timeDay).round(*date*) typically returns 12:00 AM local time on the given *date* if it is on or before noon, and 12:00 AM of the following day if it is after noon. - -This method is idempotent: if the specified *date* is already rounded to the current interval, a new date with an identical time is returned. - -# interval.ceil(date) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L12 "Source") - -Returns a new date representing the earliest interval boundary date after or equal to *date*. For example, [d3.timeDay](#timeDay).ceil(*date*) typically returns 12:00 AM local time on the date following the given *date*. - -This method is idempotent: if the specified *date* is already ceilinged to the current interval, a new date with an identical time is returned. Furthermore, the returned date is the maximum expressible value of the associated interval, such that *interval*.ceil(*interval*.ceil(*date*) + 1) returns the following interval boundary date. - -# interval.offset(date[, step]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L22 "Source") - -Returns a new date equal to *date* plus *step* intervals. If *step* is not specified it defaults to 1. If *step* is negative, then the returned date will be before the specified *date*; if *step* is zero, then a copy of the specified *date* is returned; if *step* is not an integer, it is [floored](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor). This method does not round the specified *date* to the interval. For example, if *date* is today at 5:34 PM, then [d3.timeDay](#timeDay).offset(*date*, 1) returns 5:34 PM tomorrow (even if daylight saving changes!). - -# interval.range(start, stop[, step]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L26 "Source") - -Returns an array of dates representing every interval boundary after or equal to *start* (inclusive) and before *stop* (exclusive). If *step* is specified, then every *step*th boundary will be returned; for example, for the [d3.timeDay](#timeDay) interval a *step* of 2 will return every other day. If *step* is not an integer, it is [floored](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor). - -The first date in the returned array is the earliest boundary after or equal to *start*; subsequent dates are [offset](#interval_offset) by *step* intervals and [floored](#interval_floor). Thus, two overlapping ranges may be consistent. For example, this range contains odd days: - -```js -d3.timeDay.range(new Date(2015, 0, 1), new Date(2015, 0, 7), 2); -// [Thu Jan 01 2015 00:00:00 GMT-0800 (PST), -// Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST)] -``` - -While this contains even days: - -```js -d3.timeDay.range(new Date(2015, 0, 2), new Date(2015, 0, 8), 2); -// [Fri Jan 02 2015 00:00:00 GMT-0800 (PST), -// Sun Jan 04 2015 00:00:00 GMT-0800 (PST), -// Tue Jan 06 2015 00:00:00 GMT-0800 (PST)] -``` - -To make ranges consistent when a *step* is specified, use [*interval*.every](#interval_every) instead. - -# interval.filter(test) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L35 "Source") - -Returns a new interval that is a filtered subset of this interval using the specified *test* function. The *test* function is passed a date and should return true if and only if the specified date should be considered part of the interval. For example, to create an interval that returns the 1st, 11th, 21th and 31th (if it exists) of each month: - -```js -var i = d3.timeDay.filter(function(d) { return (d.getDate() - 1) % 10 === 0; }); -``` - -The returned filtered interval does not support [*interval*.count](#interval_count). See also [*interval*.every](#interval_every). - -# interval.every(step) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L50 "Source") - -Returns a [filtered](#interval_filter) view of this interval representing every *step*th date. The meaning of *step* is dependent on this interval’s parent interval as defined by the field function. For example, [d3.timeMinute](#timeMinute).every(15) returns an interval representing every fifteen minutes, starting on the hour: :00, :15, :30, :45, etc. Note that for some intervals, the resulting dates may not be uniformly-spaced; [d3.timeDay](#timeDay)’s parent interval is [d3.timeMonth](#timeMonth), and thus the interval number resets at the start of each month. If *step* is not valid, returns null. If *step* is one, returns this interval. - -This method can be used in conjunction with [*interval*.range](#interval_range) to ensure that two overlapping ranges are consistent. For example, this range contains odd days: - -```js -d3.timeDay.every(2).range(new Date(2015, 0, 1), new Date(2015, 0, 7)); -// [Thu Jan 01 2015 00:00:00 GMT-0800 (PST), -// Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST)] -``` - -As does this one: - -```js -d3.timeDay.every(2).range(new Date(2015, 0, 2), new Date(2015, 0, 8)); -// [Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST), -// Wed Jan 07 2015 00:00:00 GMT-0800 (PST)] -``` - -The returned filtered interval does not support [*interval*.count](#interval_count). See also [*interval*.filter](#interval_filter). - -# interval.count(start, end) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L44 "Source") - -Returns the number of interval boundaries after *start* (exclusive) and before or equal to *end* (inclusive). Note that this behavior is slightly different than [*interval*.range](#interval_range) because its purpose is to return the zero-based number of the specified *end* date relative to the specified *start* date. For example, to compute the current zero-based day-of-year number: - -```js -var now = new Date; -d3.timeDay.count(d3.timeYear(now), now); // 177 -``` - -Likewise, to compute the current zero-based week-of-year number for weeks that start on Sunday: - -```js -d3.timeSunday.count(d3.timeYear(now), now); // 25 -``` - -# d3.timeInterval(floor, offset[, count[, field]]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L4 "Source") - -Constructs a new custom interval given the specified *floor* and *offset* functions and an optional *count* function. - -The *floor* function takes a single date as an argument and rounds it down to the nearest interval boundary. - -The *offset* function takes a date and an integer step as arguments and advances the specified date by the specified number of boundaries; the step may be positive, negative or zero. - -The optional *count* function takes a start date and an end date, already floored to the current interval, and returns the number of boundaries between the start (exclusive) and end (inclusive). If a *count* function is not specified, the returned interval does not expose [*interval*.count](#interval_count) or [*interval*.every](#interval_every) methods. Note: due to an internal optimization, the specified *count* function must not invoke *interval*.count on other time intervals. - -The optional *field* function takes a date, already floored to the current interval, and returns the field value of the specified date, corresponding to the number of boundaries between this date (exclusive) and the latest previous parent boundary. For example, for the [d3.timeDay](#timeDay) interval, this returns the number of days since the start of the month. If a *field* function is not specified, it defaults to counting the number of interval boundaries since the UNIX epoch of January 1, 1970 UTC. The *field* function defines the behavior of [*interval*.every](#interval_every). - -### Intervals - -The following intervals are provided: - -# d3.timeMillisecond [<>](https://github.com/d3/d3-time/blob/master/src/millisecond.js "Source") -

Internally, it uses [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) for fluid animation (if available), switching to [setTimeout](https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout) for delays longer than 24ms. - -## Installing - -If you use NPM, `npm install d3-timer`. Otherwise, download the [latest release](https://github.com/d3/d3-timer/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-timer.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -## API Reference - -# d3.now() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L15 "Source") - -Returns the current time as defined by [performance.now](https://developer.mozilla.org/en-US/docs/Web/API/Performance/now) if available, and [Date.now](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date/now) if not. The current time is updated at the start of a frame; it is thus consistent during the frame, and any timers scheduled during the same frame will be synchronized. If this method is called outside of a frame, such as in response to a user event, the current time is calculated and then fixed until the next frame, again ensuring consistent timing during event handling. - -# d3.timer(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L52 "Source") - -Schedules a new timer, invoking the specified *callback* repeatedly until the timer is [stopped](#timer_stop). An optional numeric *delay* in milliseconds may be specified to invoke the given *callback* after a delay; if *delay* is not specified, it defaults to zero. The delay is relative to the specified *time* in milliseconds; if *time* is not specified, it defaults to [now](#now). - -The *callback* is passed the (apparent) *elapsed* time since the timer became active. For example: - -```js -var t = d3.timer(function(elapsed) { - console.log(elapsed); - if (elapsed > 200) t.stop(); -}, 150); -``` - -This produces roughly the following console output: - -``` -3 -25 -48 -65 -85 -106 -125 -146 -167 -189 -209 -``` - -(The exact values may vary depending on your JavaScript runtime and what else your computer is doing.) Note that the first *elapsed* time is 3ms: this is the elapsed time since the timer started, not since the timer was scheduled. Here the timer started 150ms after it was scheduled due to the specified delay. The apparent *elapsed* time may be less than the true *elapsed* time if the page is backgrounded and [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) is paused; in the background, apparent time is frozen. - -If [timer](#timer) is called within the callback of another timer, the new timer callback (if eligible as determined by the specified *delay* and *time*) will be invoked immediately at the end of the current frame, rather than waiting until the next frame. Within a frame, timer callbacks are guaranteed to be invoked in the order they were scheduled, regardless of their start time. - -# timer.restart(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L31 "Source") - -Restart a timer with the specified *callback* and optional *delay* and *time*. This is equivalent to stopping this timer and creating a new timer with the specified arguments, although this timer retains the original invocation priority. - -# timer.stop() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L43 "Source") - -Stops this timer, preventing subsequent callbacks. This method has no effect if the timer has already stopped. - -# d3.timerFlush() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L58 "Source") - -Immediately invoke any eligible timer callbacks. Note that zero-delay timers are normally first executed after one frame (~17ms). This can cause a brief flicker because the browser renders the page twice: once at the end of the first event loop, then again immediately on the first timer callback. By flushing the timer queue at the end of the first event loop, you can run any zero-delay timers immediately and avoid the flicker. - -# d3.timeout(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timeout.js "Source") - -Like [timer](#timer), except the timer automatically [stops](#timer_stop) on its first callback.

Works in Node.js and web browsers. - -## Installation - -```bash -$ npm install debug -``` - -## Usage - -`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. - -Example [_app.js_](./examples/node/app.js): - -```js -var debug = require('debug')('http') - , http = require('http') - , name = 'My App'; - -// fake app - -debug('booting %o', name); - -http.createServer(function(req, res){ - debug(req.method + ' ' + req.url); - res.end('hello\n'); -}).listen(3000, function(){ - debug('listening'); -}); - -// fake worker of some kind - -require('./worker'); -``` - -Example [_worker.js_](./examples/node/worker.js): - -```js -var a = require('debug')('worker:a') - , b = require('debug')('worker:b'); - -function work() { - a('doing lots of uninteresting work'); - setTimeout(work, Math.random() * 1000); -} - -work(); - -function workb() { - b('doing some work'); - setTimeout(workb, Math.random() * 2000); -} - -workb(); -``` - -The `DEBUG` environment variable is then used to enable these based on space or -comma-delimited names. - -Here are some examples: - -screen shot 2017-08-08 at 12 53 04 pm -screen shot 2017-08-08 at 12 53 38 pm -screen shot 2017-08-08 at 12 53 25 pm - -#### Windows command prompt notes - -##### CMD - -On Windows the environment variable is set using the `set` command. - -```cmd -set DEBUG=*,-not_this -``` - -Example: - -```cmd -set DEBUG=* & node app.js -``` - -##### PowerShell (VS Code default) - -PowerShell uses different syntax to set environment variables. - -```cmd -$env:DEBUG = "*,-not_this" -``` - -Example: - -```cmd -$env:DEBUG='app';node app.js -``` - -Then, run the program to be debugged as usual. - -npm script example: -```js - "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js", -``` - -## Namespace Colors - -Every debug instance has a color generated for it based on its namespace name. -This helps when visually parsing the debug output to identify which debug instance -a debug line belongs to. - -#### Node.js - -In Node.js, colors are enabled when stderr is a TTY. You also _should_ install -the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, -otherwise debug will only use a small handful of basic colors. - - - -#### Web Browser - -Colors are also enabled on "Web Inspectors" that understand the `%c` formatting -option. These are WebKit web inspectors, Firefox ([since version -31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) -and the Firebug plugin for Firefox (any version). - - - - -## Millisecond diff - -When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. - - - -When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: - - - - -## Conventions - -If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. - -## Wildcards - -The `*` character may be used as a wildcard. Suppose for example your library has -debuggers named "connect:bodyParser", "connect:compress", "connect:session", -instead of listing all three with -`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do -`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. - -You can also exclude specific debuggers by prefixing them with a "-" character. -For example, `DEBUG=*,-connect:*` would include all debuggers except those -starting with "connect:". - -## Environment Variables - -When running through Node.js, you can set a few environment variables that will -change the behavior of the debug logging: - -| Name | Purpose | -|-----------|-------------------------------------------------| -| `DEBUG` | Enables/disables specific debugging namespaces. | -| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | -| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | -| `DEBUG_DEPTH` | Object inspection depth. | -| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | - - -__Note:__ The environment variables beginning with `DEBUG_` end up being -converted into an Options object that gets used with `%o`/`%O` formatters. -See the Node.js documentation for -[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) -for the complete list. - -## Formatters - -Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. -Below are the officially supported formatters: - -| Formatter | Representation | -|-----------|----------------| -| `%O` | Pretty-print an Object on multiple lines. | -| `%o` | Pretty-print an Object all on a single line. | -| `%s` | String. | -| `%d` | Number (both integer and float). | -| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | -| `%%` | Single percent sign ('%'). This does not consume an argument. | - - -### Custom formatters - -You can add custom formatters by extending the `debug.formatters` object. -For example, if you wanted to add support for rendering a Buffer as hex with -`%h`, you could do something like: - -```js -const createDebug = require('debug') -createDebug.formatters.h = (v) => { - return v.toString('hex') -} - -// …elsewhere -const debug = createDebug('foo') -debug('this is hex: %h', new Buffer('hello world')) -// foo this is hex: 68656c6c6f20776f726c6421 +0ms -``` - - -## Browser Support - -You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), -or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), -if you don't want to build it yourself. - -Debug's enable state is currently persisted by `localStorage`. -Consider the situation shown below where you have `worker:a` and `worker:b`, -and wish to debug both. You can enable this using `localStorage.debug`: - -```js -localStorage.debug = 'worker:*' -``` - -And then refresh the page. - -```js -a = debug('worker:a'); -b = debug('worker:b'); - -setInterval(function(){ - a('doing some work'); -}, 1000); - -setInterval(function(){ - b('doing some work'); -}, 1200); -``` - - -## Output streams - - By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: - -Example [_stdout.js_](./examples/node/stdout.js): - -```js -var debug = require('debug'); -var error = debug('app:error'); - -// by default stderr is used -error('goes to stderr!'); - -var log = debug('app:log'); -// set this namespace to log via console.log -log.log = console.log.bind(console); // don't forget to bind to console! -log('goes to stdout'); -error('still goes to stderr!'); - -// set all output to go via console.info -// overrides all per-namespace log settings -debug.log = console.info.bind(console); -error('now goes to stdout via console.info'); -log('still goes to stdout, but via console.info now'); -``` - -## Extend -You can simply extend debugger -```js -const log = require('debug')('auth'); - -//creates new debug instance with extended namespace -const logSign = log.extend('sign'); -const logLogin = log.extend('login'); - -log('hello'); // auth hello -logSign('hello'); //auth:sign hello -logLogin('hello'); //auth:login hello -``` - -## Set dynamically - -You can also enable debug dynamically by calling the `enable()` method : - -```js -let debug = require('debug'); - -console.log(1, debug.enabled('test')); - -debug.enable('test'); -console.log(2, debug.enabled('test')); - -debug.disable(); -console.log(3, debug.enabled('test')); - -``` - -print : -``` -1 false -2 true -3 false -``` - -Usage : -`enable(namespaces)` -`namespaces` can include modes separated by a colon and wildcards. - -Note that calling `enable()` completely overrides previously set DEBUG variable : - -``` -$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' -=> false -``` - -## Checking whether a debug target is enabled - -After you've created a debug instance, you can determine whether or not it is -enabled by checking the `enabled` property: - -```javascript -const debug = require('debug')('http'); - -if (debug.enabled) { - // do stuff... -} -``` - -You can also manually toggle this property to force the debug instance to be -enabled or disabled. - - -## Authors - - - TJ Holowaychuk - - Nathan Rajlich - - Andrew Rhyne - -## Backers - -Support us with a monthly donation and help us continue our activities.

If you were using a custom theme, or - referring to one directly (eg via `Gauge.unicode` or `Gauge.ascii`) then - you'll need to change your code. You can get the equivalent of the latter - with: - ``` - var themes = require('gauge/themes') - var unicodeTheme = themes(true, true) // returns the color unicode theme for your platform - ``` - The default themes no longer use any ambiguous width characters, so even - if you choose to display those as wide your progress bar should still - display correctly. -* Templates are entirely different and if you were using a custom one, you - should consult the documentation to learn how to recreate it. If you were - using the default, be aware that it has changed and the result looks quite - a bit different. diff --git a/node_modules/gauge/LICENSE b/node_modules/gauge/LICENSE deleted file mode 100644 index e756052..0000000 --- a/node_modules/gauge/LICENSE +++ /dev/null @@ -1,13 +0,0 @@ -Copyright (c) 2014, Rebecca Turner - -Permission to use, copy, modify, and/or distribute this software for any -purpose with or without fee is hereby granted, provided that the above -copyright notice and this permission notice appear in all copies. - -THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES -WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS.

When this is true a timer is created to trigger once every - `updateInterval` ms, when false, updates are printed as soon as they come - in but updates more often than `updateInterval` are ignored. The reason - 0.8 doesn't have this set to true is that it can't `unref` its timer and - so it would stop your program from exiting– if you want to use this - feature with 0.8 just make sure you call `gauge.disable()` before you - expect your program to exit. -* **themes**: A themeset to use when selecting the theme to use. Defaults - to `gauge/themes`, see the [themes] documentation for details. -* **theme**: Select a theme for use, it can be a: - * Theme object, in which case the **themes** is not used. - * The name of a theme, which will be looked up in the current *themes* - object. - * A configuration object with any of `hasUnicode`, `hasColor` or - `platform` keys, which if wlll be used to override our guesses when making - a default theme selection. - - If no theme is selected then a default is picked using a combination of our - best guesses at your OS, color support and unicode support. -* **template**: Describes what you want your gauge to look like. The - default is what npm uses. Detailed [documentation] is later in this - document. -* **hideCursor**: Defaults to true. If true, then the cursor will be hidden - while the gauge is displayed. -* **tty**: The tty that you're ultimately writing to. Defaults to the same - as **stream**. This is used for detecting the width of the terminal and - resizes. The width used is `tty.columns - 1`. If no tty is available then - a width of `79` is assumed. -* **enabled**: Defaults to true if `tty` is a TTY, false otherwise. If true - the gauge starts enabled. If disabled then all update commands are - ignored and no gauge will be printed until you call `.enable()`. -* **Plumbing**: The class to use to actually generate the gauge for - printing. This defaults to `require('gauge/plumbing')` and ordinarly you - shouldn't need to override this. -* **cleanupOnExit**: Defaults to true. Ordinarily we register an exit - handler to make sure your cursor is turned back on and the progress bar - erased when your process exits, even if you Ctrl-C out or otherwise exit - unexpectedly. You can disable this and it won't register the exit handler. - -[has-unicode]: https://www.npmjs.com/package/has-unicode -[themes]: #themes -[documentation]: #templates - -#### `gauge.show(section | status, [completed])` - -The first argument is either the section, the name of the current thing -contributing to progress, or an object with keys like **section**, -**subsection** & **completed** (or any others you have types for in a custom -template). If you don't want to update or set any of these you can pass -`null` and it will be ignored. - -The second argument is the percent completed as a value between 0 and 1. -Without it, completion is just not updated. You'll also note that completion -can be passed in as part of a status object as the first argument. If both -it and the completed argument are passed in, the completed argument wins. - -#### `gauge.hide([cb])` - -Removes the gauge from the terminal. Optionally, callback `cb` after IO has -had an opportunity to happen (currently this just means after `setImmediate` -has called back.) - -It turns out this is important when you're pausing the progress bar on one -filehandle and printing to another– otherwise (with a big enough print) node -can end up printing the "end progress bar" bits to the progress bar filehandle -while other stuff is printing to another filehandle.

The properties in the theme are used when their name matches a type in -the template. Their values can be: - -* **strings & numbers** - They'll be included as is -* **function (values, theme, width)** - Should return what you want in your output. - *values* is an object with values provided via `gauge.show`, - *theme* is the theme specific to this item (see below) or this theme object, - and *width* is the number of characters wide your result should be. - -There are a couple of special prefixes: - -* **pre** - Is shown prior to the property, if its displayed. -* **post** - Is shown after the property, if its displayed. - -And one special suffix: - -* **Theme** - Its value is passed to a function-type item as the theme. - -#### themes.addToAllThemes(theme) - -This *mixes-in* `theme` into all themes currently defined. It also adds it -to the default parent theme for this themeset, so future themes added to -this themeset will get the values from `theme` by default. - -#### themes.newThemeset() - -Copy the current themeset into a new one. This allows you to easily inherit -one themeset from another. - -### TEMPLATES - -A template is an array of objects and strings that, after being evaluated, -will be turned into the gauge line. The default template is: - -```javascript -[ - {type: 'progressbar', length: 20}, - {type: 'activityIndicator', kerning: 1, length: 1}, - {type: 'section', kerning: 1, default: ''}, - {type: 'subsection', kerning: 1, default: ''} -] -``` - -The various template elements can either be **plain strings**, in which case they will -be be included verbatum in the output, or objects with the following properties: - -* *type* can be any of the following plus any keys you pass into `gauge.show` plus - any keys you have on a custom theme. - * `section` – What big thing you're working on now. - * `subsection` – What component of that thing is currently working. - * `activityIndicator` – Shows a spinner using the `activityIndicatorTheme` - from your active theme. - * `progressbar` – A progress bar representing your current `completed` - using the `progressbarTheme` from your active theme. -* *kerning* – Number of spaces that must be between this item and other - items, if this item is displayed at all. -* *maxLength* – The maximum length for this element. If its value is longer it - will be truncated. -* *minLength* – The minimum length for this element. If its value is shorter it - will be padded according to the *align* value. -* *align* – (Default: left) Possible values "left", "right" and "center". Works - as you'd expect from word processors. -* *length* – Provides a single value for both *minLength* and *maxLength*. If both - *length* and *minLength or *maxLength* are specifed then the latter take precedence. -* *value* – A literal value to use for this template item. -* *default* – A default value to use for this template item if a value - wasn't otherwise passed in. - -### PLUMBING - -This is the super simple, assume nothing, do no magic internals used by gauge to -implement its ordinary interface. - -``` -var Plumbing = require('gauge/plumbing') -var gauge = new Plumbing(theme, template, width) -``` -

Braced sections start with `{` and end with `}`, with any -number of comma-delimited sections within. Braced sections may contain -slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`. - -The following characters have special magic meaning when used in a -path portion: - -* `*` Matches 0 or more characters in a single path portion -* `?` Matches 1 character -* `[...]` Matches a range of characters, similar to a RegExp range. - If the first character of the range is `!` or `^` then it matches - any character not in the range. -* `!(pattern|pattern|pattern)` Matches anything that does not match - any of the patterns provided. -* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the - patterns provided. -* `+(pattern|pattern|pattern)` Matches one or more occurrences of the - patterns provided. -* `*(a|b|c)` Matches zero or more occurrences of the patterns provided -* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns - provided -* `**` If a "globstar" is alone in a path portion, then it matches - zero or more directories and subdirectories searching for matches. - It does not crawl symlinked directories. - -### Dots - -If a file or directory path portion has a `.` as the first character, -then it will not match any glob pattern unless that pattern's -corresponding path part also has a `.` as its first character. - -For example, the pattern `a/.*/c` would match the file at `a/.b/c`. -However the pattern `a/*/c` would not, because `*` does not start with -a dot character. - -You can make glob treat dots as normal characters by setting -`dot:true` in the options. - -### Basename Matching - -If you set `matchBase:true` in the options, and the pattern has no -slashes in it, then it will seek for any file anywhere in the tree -with a matching basename. For example, `*.js` would match -`test/simple/basic.js`. - -### Empty Sets - -If no matching files are found, then an empty array is returned. This -differs from the shell, where the pattern itself is returned. For -example: - - $ echo a*s*d*f - a*s*d*f - -To get the bash-style behavior, set the `nonull:true` in the options. - -### See Also: - -* `man sh` -* `man bash` (Search for "Pattern Matching") -* `man 3 fnmatch` -* `man 5 gitignore` -* [minimatch documentation](https://github.com/isaacs/minimatch) - -## glob.hasMagic(pattern, [options]) - -Returns `true` if there are any special characters in the pattern, and -`false` otherwise. - -Note that the options affect the results.

There - is no way at this time to continue a glob search after aborting, but - you can re-use the statCache to avoid having to duplicate syscalls. -* `cache` Convenience object. Each field has the following possible - values: - * `false` - Path does not exist - * `true` - Path exists - * `'FILE'` - Path exists, and is not a directory - * `'DIR'` - Path exists, and is a directory - * `[file, entries, ...]` - Path exists, is a directory, and the - array value is the results of `fs.readdir` -* `statCache` Cache of `fs.stat` results, to prevent statting the same - path multiple times. -* `symlinks` A record of which paths are symbolic links, which is - relevant in resolving `**` patterns. -* `realpathCache` An optional object which is passed to `fs.realpath` - to minimize unnecessary syscalls. It is stored on the instantiated - Glob object, and may be re-used. - -### Events - -* `end` When the matching is finished, this is emitted with all the - matches found. If the `nonull` option is set, and no match was found, - then the `matches` list contains the original pattern. The matches - are sorted, unless the `nosort` flag is set. -* `match` Every time a match is found, this is emitted with the specific - thing that matched. It is not deduplicated or resolved to a realpath. -* `error` Emitted when an unexpected error is encountered, or whenever - any fs error occurs if `options.strict` is set. -* `abort` When `abort()` is called, this event is raised. - -### Methods - -* `pause` Temporarily stop the search -* `resume` Resume the search -* `abort` Stop the search forever - -### Options - -All the options that can be passed to Minimatch can also be passed to -Glob to change pattern matching behavior. Also, some have been added, -or have glob-specific ramifications. - -All options are false by default, unless otherwise noted. - -All options are added to the Glob object, as well. - -If you are running many `glob` operations, you can pass a Glob object -as the `options` argument to a subsequent operation to shortcut some -`stat` and `readdir` calls. At the very least, you may pass in shared -`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that -parallel glob operations will be sped up by sharing information about -the filesystem. - -* `cwd` The current working directory in which to search. Defaults - to `process.cwd()`. -* `root` The place where patterns starting with `/` will be mounted - onto. Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix - systems, and `C:\` or some such on Windows.) -* `dot` Include `.dot` files in normal matches and `globstar` matches. - Note that an explicit dot in a portion of the pattern will always - match dot files. -* `nomount` By default, a pattern starting with a forward-slash will be - "mounted" onto the root setting, so that a valid filesystem path is - returned. Set this flag to disable that behavior. -* `mark` Add a `/` character to directory matches. Note that this - requires additional stat calls. -* `nosort` Don't sort the results. -* `stat` Set to true to stat *all* results. This reduces performance - somewhat, and is completely unnecessary, unless `readdir` is presumed - to be an untrustworthy indicator of file existence. -* `silent` When an unusual error is encountered when attempting to - read a directory, a warning will be printed to stderr. Set the - `silent` option to true to suppress these warnings. -* `strict` When an unusual error is encountered when attempting to - read a directory, the process will just continue on in search of - other matches. Set the `strict` option to raise an error in these - cases. -* `cache` See `cache` property above. Pass in a previously generated - cache object to save some fs calls. -* `statCache` A cache of results of filesystem information, to prevent - unnecessary stat calls. While it should not normally be necessary - to set this, you may pass the statCache from one glob() call to the - options object of another, if you know that the filesystem will not - change between calls. (See "Race Conditions" below.) -* `symlinks` A cache of known symbolic links. You may pass in a - previously generated `symlinks` object to save `lstat` calls when - resolving `**` matches. -* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead. -* `nounique` In some cases, brace-expanded patterns can result in the - same file showing up multiple times in the result set. By default, - this implementation prevents duplicates in the result set. Set this - flag to disable that behavior. -* `nonull` Set to never return an empty set, instead returning a set - containing the pattern itself. This is the default in glob(3). -* `debug` Set to enable debug logging in minimatch and glob. -* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets. -* `noglobstar` Do not match `**` against multiple filenames. (Ie, - treat it as a normal `*` instead.) -* `noext` Do not match `+(a|b)` "extglob" patterns. -* `nocase` Perform a case-insensitive match. Note: on - case-insensitive filesystems, non-magic patterns will match by - default, since `stat` and `readdir` will not raise errors. -* `matchBase` Perform a basename-only match if the pattern does not - contain any slash characters. That is, `*.js` would be treated as - equivalent to `**/*.js`, matching all js files in all directories. -* `nodir` Do not match directories, only files. (Note: to match - *only* directories, simply put a `/` at the end of the pattern.) -* `ignore` Add a pattern or an array of glob patterns to exclude matches. - Note: `ignore` patterns are *always* in `dot:true` mode, regardless - of any other settings. -* `follow` Follow symlinked directories when expanding `**` patterns. - Note that this can result in a lot of duplicate references in the - presence of cyclic links. -* `realpath` Set to true to call `fs.realpath` on all of the results. - In the case of a symlink that cannot be resolved, the full absolute - path to the matched entry is returned (though it will usually be a - broken symlink) -* `absolute` Set to true to always receive absolute paths for matched - files. Unlike `realpath`, this also affects the values returned in - the `match` event. - -## Comparisons to other fnmatch/glob implementations - -While strict compliance with the existing standards is a worthwhile -goal, some discrepancies exist between node-glob and other -implementations, and are intentional. - -The double-star character `**` is supported by default, unless the -`noglobstar` flag is set. This is supported in the manner of bsdglob -and bash 4.3, where `**` only has special significance if it is the only -thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but -`a/**b` will not. - -Note that symlinked directories are not crawled as part of a `**`, -though their contents may match against subsequent portions of the -pattern. This prevents infinite loops and duplicates and the like. - -If an escaped pattern has no matches, and the `nonull` flag is set, -then glob returns the pattern as-provided, rather than -interpreting the character escapes. For example, -`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than -`"*a?"`. This is akin to setting the `nullglob` option in bash, except -that it does not resolve escaped pattern characters. - -If brace expansion is not disabled, then it is performed before any -other interpretation of the glob pattern. Thus, a pattern like -`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded -**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are -checked for validity. Since those two are valid, matching proceeds. - -### Comments and Negation - -Previously, this module let you mark a pattern as a "comment" if it -started with a `#` character, or a "negated" pattern if it started -with a `!` character. - -These options were deprecated in version 5, and removed in version 6. - -To specify things that should not match, use the `ignore` option. - -## Windows - -**Please only use forward-slashes in glob expressions.** - -Though windows uses either `/` or `\` as its path separator, only `/` -characters are used by this glob implementation. You must use -forward-slashes **only** in glob expressions. Back-slashes will always -be interpreted as escape characters, not path separators. - -Results from absolute patterns such as `/foo/*` are mounted onto the -root setting using `path.join`. On windows, this will by default result -in `/foo/*` matching `C:\foo\bar.txt`. - -## Race Conditions - -Glob searching, by its very nature, is susceptible to race conditions, -since it relies on directory walking and such. - -As a result, it is possible that a file that exists when glob looks for -it may have been deleted or modified by the time it returns the result. - -As part of its internal implementation, this program caches all stat -and readdir calls that it makes, in order to cut down on system -overhead. However, this also makes it even more susceptible to races, -especially if the cache or statCache objects are reused between glob -calls. - -Users are thus advised not to use a glob result as a guarantee of -filesystem state in the face of rapid changes. For the vast majority -of operations, this is never a problem. - -## Glob Logo -Glob's logo was created by [Tanya Brassie](http://tanyabrassie.com/).

Each item in the row - corresponds to a single path-part. For example, the pattern - `{a,b/c}/d` would expand to a set of patterns like: - - [ [ a, d ] - , [ b, c, d ] ] - - If a portion of the pattern doesn't have any "magic" in it - (that is, it's something like `"foo"` rather than `fo*o?`), then it - will be left as a string rather than converted to a regular - expression. - -* `regexp` Created by the `makeRe` method. A single regular expression - expressing the entire pattern. This is useful in cases where you wish - to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled. -* `negate` True if the pattern is negated. -* `comment` True if the pattern is a comment. -* `empty` True if the pattern is `""`. - -### Methods - -* `makeRe` Generate the `regexp` member if necessary, and return it. - Will return `false` if the pattern is invalid. -* `match(fname)` Return true if the filename matches the pattern, or - false otherwise. -* `matchOne(fileArray, patternArray, partial)` Take a `/`-split - filename, and match it against a single row in the `regExpSet`. This - method is mainly for internal use, but is exposed so that it can be - used by a glob-walker that needs to avoid excessive filesystem calls. - -All other methods are internal, and will be called as necessary. - -### minimatch(path, pattern, options) - -Main export. Tests a path against the pattern using the options. - -```javascript -var isJS = minimatch(file, "*.js", { matchBase: true }) -``` - -### minimatch.filter(pattern, options) - -Returns a function that tests its -supplied argument, suitable for use with `Array.filter`. Example: - -```javascript -var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true})) -``` - -### minimatch.match(list, pattern, options) - -Match against the list of -files, in the style of fnmatch or glob. If nothing is matched, and -options.nonull is set, then return a list containing the pattern itself. - -```javascript -var javascripts = minimatch.match(fileList, "*.js", {matchBase: true})) -``` - -### minimatch.makeRe(pattern, options) - -Make a regular expression object from the pattern. - -## Options - -All options are `false` by default. - -### debug - -Dump a ton of stuff to stderr. - -### nobrace - -Do not expand `{a,b}` and `{1..3}` brace sets. - -### noglobstar - -Disable `**` matching against multiple folder names. - -### dot - -Allow patterns to match filenames starting with a period, even if -the pattern does not explicitly have a period in that spot. - -Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot` -is set. - -### noext - -Disable "extglob" style patterns like `+(a|b)`. - -### nocase - -Perform a case-insensitive match. - -### nonull - -When a match is not found by `minimatch.match`, return a list containing -the pattern itself if this option is set. When not set, an empty list -is returned if there are no matches. - -### matchBase - -If set, then patterns without slashes will be matched -against the basename of the path if it contains slashes. For example, -`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. - -### nocomment - -Suppress the behavior of treating `#` at the start of a pattern as a -comment. - -### nonegate - -Suppress the behavior of treating a leading `!` character as negation. - -### flipNegate - -Returns from negate expressions the same as if they were not negated. -(Ie, true on a hit, false on a miss.) - - -## Comparisons to other fnmatch/glob implementations - -While strict compliance with the existing standards is a worthwhile -goal, some discrepancies exist between minimatch and other -implementations, and are intentional. - -If the pattern starts with a `!` character, then it is negated. Set the -`nonegate` flag to suppress this behavior, and treat leading `!` -characters normally. This is perhaps relevant if you wish to start the -pattern with a negative extglob pattern like `!(a|B)`. Multiple `!` -characters at the start of a pattern will negate the pattern multiple -times. - -If a pattern starts with `#`, then it is treated as a comment, and -will not match anything. Use `\#` to match a literal `#` at the -start of a line, or set the `nocomment` flag to suppress this behavior. - -The double-star character `**` is supported by default, unless the -`noglobstar` flag is set. This is supported in the manner of bsdglob -and bash 4.1, where `**` only has special significance if it is the only -thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but -`a/**b` will not. - -If an escaped pattern has no matches, and the `nonull` flag is set, -then minimatch.match returns the pattern as-provided, rather than -interpreting the character escapes. For example, -`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than -`"*a?"`. This is akin to setting the `nullglob` option in bash, except -that it does not resolve escaped pattern characters. - -If brace expansion is not disabled, then it is performed before any -other interpretation of the glob pattern. Thus, a pattern like -`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded -**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are -checked for validity. Since those two are valid, matching proceeds. diff --git a/node_modules/minimatch/minimatch.js b/node_modules/minimatch/minimatch.js deleted file mode 100644 index 5b5f8cf..0000000 --- a/node_modules/minimatch/minimatch.js +++ /dev/null @@ -1,923 +0,0 @@ -module.exports = minimatch -minimatch.Minimatch = Minimatch - -var path = { sep: '/' } -try { - path = require('path') -} catch (er) {} - -var GLOBSTAR = minimatch.GLOBSTAR = Minimatch.GLOBSTAR = {} -var expand = require('brace-expansion') - -var plTypes = { - '!': { open: '(?:(?!(?:', close: '))[^/]*?)'}, - '?': { open: '(?:', close: ')?' }, - '+': { open: '(?:', close: ')+' }, - '*': { open: '(?:', close: ')*' }, - '@': { open: '(?:', close: ')' } -} - -// any single thing other than / -// don't need to escape / when using new RegExp() -var qmark = '[^/]' - -// * => any number of characters -var star = qmark + '*?' - -// ** when dots are allowed.

Otherwise, it'll do a minimal amount of Buffer -copying to ensure proper Streams semantics when `read(n)` is called. - -`objectMode` can also be set by doing `stream.objectMode = true`, or by -writing any non-string/non-buffer data. `objectMode` cannot be set to -false once it is set. - -This is not a `through` or `through2` stream. It doesn't transform -the data, it just passes it right through. If you want to transform -the data, extend the class, and override the `write()` method. Once -you're done transforming the data however you want, call -`super.write()` with the transform output. - -For some examples of streams that extend Minipass in various ways, check -out: - -- [minizlib](http://npm.im/minizlib) -- [fs-minipass](http://npm.im/fs-minipass) -- [tar](http://npm.im/tar) -- [minipass-collect](http://npm.im/minipass-collect) -- [minipass-flush](http://npm.im/minipass-flush) -- [minipass-pipeline](http://npm.im/minipass-pipeline) -- [tap](http://npm.im/tap) -- [tap-parser](http://npm.im/tap) -- [treport](http://npm.im/tap) - -## Differences from Node.js Streams - -There are several things that make Minipass streams different from (and in -some ways superior to) Node.js core streams. - -Please read these caveats if you are familiar with noode-core streams and -intend to use Minipass streams in your programs. - -### Timing - -Minipass streams are designed to support synchronous use-cases. Thus, data -is emitted as soon as it is available, always. It is buffered until read, -but no longer. Another way to look at it is that Minipass streams are -exactly as synchronous as the logic that writes into them. - -This can be surprising if your code relies on `PassThrough.write()` always -providing data on the next tick rather than the current one, or being able -to call `resume()` and not have the entire buffer disappear immediately. - -However, without this synchronicity guarantee, there would be no way for -Minipass to achieve the speeds it does, or support the synchronous use -cases that it does. Simply put, waiting takes time. - -This non-deferring approach makes Minipass streams much easier to reason -about, especially in the context of Promises and other flow-control -mechanisms. - -### No High/Low Water Marks - -Node.js core streams will optimistically fill up a buffer, returning `true` -on all writes until the limit is hit, even if the data has nowhere to go. -Then, they will not attempt to draw more data in until the buffer size dips -below a minimum value. - -Minipass streams are much simpler. The `write()` method will return `true` -if the data has somewhere to go (which is to say, given the timing -guarantees, that the data is already there by the time `write()` returns). - -If the data has nowhere to go, then `write()` returns false, and the data -sits in a buffer, to be drained out immediately as soon as anyone consumes -it. - -### Hazards of Buffering (or: Why Minipass Is So Fast) - -Since data written to a Minipass stream is immediately written all the way -through the pipeline, and `write()` always returns true/false based on -whether the data was fully flushed, backpressure is communicated -immediately to the upstream caller. This minimizes buffering. - -Consider this case: - -```js -const {PassThrough} = require('stream') -const p1 = new PassThrough({ highWaterMark: 1024 }) -const p2 = new PassThrough({ highWaterMark: 1024 }) -const p3 = new PassThrough({ highWaterMark: 1024 }) -const p4 = new PassThrough({ highWaterMark: 1024 }) - -p1.pipe(p2).pipe(p3).pipe(p4) -p4.on('data', () => console.log('made it through')) - -// this returns false and buffers, then writes to p2 on next tick (1) -// p2 returns false and buffers, pausing p1, then writes to p3 on next tick (2) -// p3 returns false and buffers, pausing p2, then writes to p4 on next tick (3) -// p4 returns false and buffers, pausing p3, then emits 'data' and 'drain' -// on next tick (4) -// p3 sees p4's 'drain' event, and calls resume(), emitting 'resume' and -// 'drain' on next tick (5) -// p2 sees p3's 'drain', calls resume(), emits 'resume' and 'drain' on next tick (6) -// p1 sees p2's 'drain', calls resume(), emits 'resume' and 'drain' on next -// tick (7) - -p1.write(Buffer.alloc(2048)) // returns false -``` - -Along the way, the data was buffered and deferred at each stage, and -multiple event deferrals happened, for an unblocked pipeline where it was -perfectly safe to write all the way through! - -Furthermore, setting a `highWaterMark` of `1024` might lead someone reading -the code to think an advisory maximum of 1KiB is being set for the -pipeline. However, the actual advisory buffering level is the _sum_ of -`highWaterMark` values, since each one has its own bucket. - -Consider the Minipass case: - -```js -const m1 = new Minipass() -const m2 = new Minipass() -const m3 = new Minipass() -const m4 = new Minipass() - -m1.pipe(m2).pipe(m3).pipe(m4) -m4.on('data', () => console.log('made it through')) - -// m1 is flowing, so it writes the data to m2 immediately -// m2 is flowing, so it writes the data to m3 immediately -// m3 is flowing, so it writes the data to m4 immediately -// m4 is flowing, so it fires the 'data' event immediately, returns true -// m4's write returned true, so m3 is still flowing, returns true -// m3's write returned true, so m2 is still flowing, returns true -// m2's write returned true, so m1 is still flowing, returns true -// No event deferrals or buffering along the way! - -m1.write(Buffer.alloc(2048)) // returns true -``` - -It is extremely unlikely that you _don't_ want to buffer any data written, -or _ever_ buffer data that can be flushed all the way through. Neither -node-core streams nor Minipass ever fail to buffer written data, but -node-core streams do a lot of unnecessary buffering and pausing. - -As always, the faster implementation is the one that does less stuff and -waits less time to do it. - -### Immediately emit `end` for empty streams (when not paused) - -If a stream is not paused, and `end()` is called before writing any data -into it, then it will emit `end` immediately. - -If you have logic that occurs on the `end` event which you don't want to -potentially happen immediately (for example, closing file descriptors, -moving on to the next entry in an archive parse stream, etc.) then be sure -to call `stream.pause()` on creation, and then `stream.resume()` once you -are ready to respond to the `end` event. - -### Emit `end` When Asked - -One hazard of immediately emitting `'end'` is that you may not yet have had -a chance to add a listener. In order to avoid this hazard, Minipass -streams safely re-emit the `'end'` event if a new listener is added after -`'end'` has been emitted. - -Ie, if you do `stream.on('end', someFunction)`, and the stream has already -emitted `end`, then it will call the handler right away. (You can think of -this somewhat like attaching a new `.then(fn)` to a previously-resolved -Promise.) - -To prevent calling handlers multiple times who would not expect multiple -ends to occur, all listeners are removed from the `'end'` event whenever it -is emitted. - -### Impact of "immediate flow" on Tee-streams - -A "tee stream" is a stream piping to multiple destinations: - -```js -const tee = new Minipass() -t.pipe(dest1) -t.pipe(dest2) -t.write('foo') // goes to both destinations -``` - -Since Minipass streams _immediately_ process any pending data through the -pipeline when a new pipe destination is added, this can have surprising -effects, especially when a stream comes in from some other function and may -or may not have data in its buffer. - -```js -// WARNING! WILL LOSE DATA! -const src = new Minipass() -src.write('foo') -src.pipe(dest1) // 'foo' chunk flows to dest1 immediately, and is gone -src.pipe(dest2) // gets nothing! -``` - -The solution is to create a dedicated tee-stream junction that pipes to -both locations, and then pipe to _that_ instead. - -```js -// Safe example: tee to both places -const src = new Minipass() -src.write('foo') -const tee = new Minipass() -tee.pipe(dest1) -tee.pipe(dest2) -stream.pipe(tee) // tee gets 'foo', pipes to both locations -``` - -The same caveat applies to `on('data')` event listeners. The first one -added will _immediately_ receive all of the data, leaving nothing for the -second: - -```js -// WARNING! WILL LOSE DATA! -const src = new Minipass() -src.write('foo') -src.on('data', handler1) // receives 'foo' right away -src.on('data', handler2) // nothing to see here! -``` - -Using a dedicated tee-stream can be used in this case as well: - -```js -// Safe example: tee to both data handlers -const src = new Minipass() -src.write('foo') -const tee = new Minipass() -tee.on('data', handler1) -tee.on('data', handler2) -src.pipe(tee) -``` - -## USAGE - -It's a stream! Use it like a stream and it'll most likely do what you want. - -```js -const Minipass = require('minipass') -const mp = new Minipass(options) // optional: { encoding, objectMode } -mp.write('foo') -mp.pipe(someOtherStream) -mp.end('bar') -``` - -### OPTIONS - -* `encoding` How would you like the data coming _out_ of the stream to be - encoded? Accepts any values that can be passed to `Buffer.toString()`. -* `objectMode` Emit data exactly as it comes in. This will be flipped on - by default if you write() something other than a string or Buffer at any - point. Setting `objectMode: true` will prevent setting any encoding - value. - -### API - -Implements the user-facing portions of Node.js's `Readable` and `Writable` -streams. - -### Methods - -* `write(chunk, [encoding], [callback])` - Put data in. (Note that, in the - base Minipass class, the same data will come out.) Returns `false` if - the stream will buffer the next write, or true if it's still in - "flowing" mode. -* `end([chunk, [encoding]], [callback])` - Signal that you have no more - data to write. This will queue an `end` event to be fired when all the - data has been consumed. -* `setEncoding(encoding)` - Set the encoding for data coming of the - stream. This can only be done once. -* `pause()` - No more data for a while, please. This also prevents `end` - from being emitted for empty streams until the stream is resumed. -* `resume()` - Resume the stream. If there's data in the buffer, it is - all discarded. Any buffered events are immediately emitted. -* `pipe(dest)` - Send all output to the stream provided. There is no way - to unpipe. When data is emitted, it is immediately written to any and - all pipe destinations. -* `on(ev, fn)`, `emit(ev, fn)` - Minipass streams are EventEmitters. - Some events are given special treatment, however. (See below under - "events".) -* `promise()` - Returns a Promise that resolves when the stream emits - `end`, or rejects if the stream emits `error`. -* `collect()` - Return a Promise that resolves on `end` with an array - containing each chunk of data that was emitted, or rejects if the - stream emits `error`. Note that this consumes the stream data. -* `concat()` - Same as `collect()`, but concatenates the data into a - single Buffer object. Will reject the returned promise if the stream is - in objectMode, or if it goes into objectMode by the end of the data. -* `read(n)` - Consume `n` bytes of data out of the buffer. If `n` is not - provided, then consume all of it. If `n` bytes are not available, then - it returns null. **Note** consuming streams in this way is less - efficient, and can lead to unnecessary Buffer copying. -* `destroy([er])` - Destroy the stream. If an error is provided, then an - `'error'` event is emitted. If the stream has a `close()` method, and - has not emitted a `'close'` event yet, then `stream.close()` will be - called. Any Promises returned by `.promise()`, `.collect()` or - `.concat()` will be rejected. After being destroyed, writing to the - stream will emit an error. No more data will be emitted if the stream is - destroyed, even if it was previously buffered. - -### Properties - -* `bufferLength` Read-only. Total number of bytes buffered, or in the case - of objectMode, the total number of objects. -* `encoding` The encoding that has been set. (Setting this is equivalent - to calling `setEncoding(enc)` and has the same prohibition against - setting multiple times.) -* `flowing` Read-only. Boolean indicating whether a chunk written to the - stream will be immediately emitted. -* `emittedEnd` Read-only. Boolean indicating whether the end-ish events - (ie, `end`, `prefinish`, `finish`) have been emitted. Note that - listening on any end-ish event will immediateyl re-emit it if it has - already been emitted. -* `writable` Whether the stream is writable. Default `true`. Set to - `false` when `end()` -* `readable` Whether the stream is readable. Default `true`. -* `buffer` A [yallist](http://npm.im/yallist) linked list of chunks written - to the stream that have not yet been emitted. (It's probably a bad idea - to mess with this.) -* `pipes` A [yallist](http://npm.im/yallist) linked list of streams that - this stream is piping into. (It's probably a bad idea to mess with - this.) -* `destroyed` A getter that indicates whether the stream was destroyed. -* `paused` True if the stream has been explicitly paused, otherwise false. -* `objectMode` Indicates whether the stream is in `objectMode`. Once set - to `true`, it cannot be set to `false`. - -### Events - -* `data` Emitted when there's data to read. Argument is the data to read. - This is never emitted while not flowing. If a listener is attached, that - will resume the stream. -* `end` Emitted when there's no more data to read. This will be emitted - immediately for empty streams when `end()` is called. If a listener is - attached, and `end` was already emitted, then it will be emitted again. - All listeners are removed when `end` is emitted. -* `prefinish` An end-ish event that follows the same logic as `end` and is - emitted in the same conditions where `end` is emitted. Emitted after - `'end'`. -* `finish` An end-ish event that follows the same logic as `end` and is - emitted in the same conditions where `end` is emitted. Emitted after - `'prefinish'`. -* `close` An indication that an underlying resource has been released. - Minipass does not emit this event, but will defer it until after `end` - has been emitted, since it throws off some stream libraries otherwise. -* `drain` Emitted when the internal buffer empties, and it is again - suitable to `write()` into the stream. -* `readable` Emitted when data is buffered and ready to be read by a - consumer. -* `resume` Emitted when stream changes state from buffering to flowing - mode. (Ie, when `resume` is called, `pipe` is called, or a `data` event - listener is added.) - -### Static Methods - -* `Minipass.isStream(stream)` Returns `true` if the argument is a stream, - and false otherwise. To be considered a stream, the object must be - either an instance of Minipass, or an EventEmitter that has either a - `pipe()` method, or both `write()` and `end()` methods. (Pretty much any - stream in node-land will return `true` for this.) - -## EXAMPLES - -Here are some examples of things you can do with Minipass streams. - -### simple "are you done yet" promise - -```js -mp.promise().then(() => { - // stream is finished -}, er => { - // stream emitted an error -}) -``` - -### collecting - -```js -mp.collect().then(all => { - // all is an array of all the data emitted - // encoding is supported in this case, so - // so the result will be a collection of strings if - // an encoding is specified, or buffers/objects if not. - // - // In an async function, you may do - // const data = await stream.collect() -}) -``` - -### collecting into a single blob - -This is a bit slower because it concatenates the data into one chunk for -you, but if you're going to do it yourself anyway, it's convenient this -way: - -```js -mp.concat().then(onebigchunk => { - // onebigchunk is a string if the stream - // had an encoding set, or a buffer otherwise. -}) -``` - -### iteration - -You can iterate over streams synchronously or asynchronously in -platforms that support it. - -Synchronous iteration will end when the currently available data is -consumed, even if the `end` event has not been reached.

You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information. - -In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type. - -* **Method argument types** - - Nan::FunctionCallbackInfo - - Nan::PropertyCallbackInfo - - Nan::ReturnValue -* **Method declarations** - - Method declaration - - Getter declaration - - Setter declaration - - Property getter declaration - - Property setter declaration - - Property enumerator declaration - - Property deleter declaration - - Property query declaration - - Index getter declaration - - Index setter declaration - - Index enumerator declaration - - Index deleter declaration - - Index query declaration -* Method and template helpers - - Nan::SetMethod() - - Nan::SetPrototypeMethod() - - Nan::SetAccessor() - - Nan::SetNamedPropertyHandler() - - Nan::SetIndexedPropertyHandler() - - Nan::SetTemplate() - - Nan::SetPrototypeTemplate() - - Nan::SetInstanceTemplate() - - Nan::SetCallHandler() - - Nan::SetCallAsFunctionHandler() - -### Scopes - -A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works. - -A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope. - -The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these. - - - Nan::HandleScope - - Nan::EscapableHandleScope - -Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection). - -### Persistent references - -An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed. - -Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported. - - - Nan::PersistentBase & v8::PersistentBase - - Nan::NonCopyablePersistentTraits & v8::NonCopyablePersistentTraits - - Nan::CopyablePersistentTraits & v8::CopyablePersistentTraits - - Nan::Persistent - - Nan::Global - - Nan::WeakCallbackInfo - - Nan::WeakCallbackType - -Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles). - -### New - -NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8. - - - Nan::New() - - Nan::Undefined() - - Nan::Null() - - Nan::True() - - Nan::False() - - Nan::EmptyString() - - -### Converters - -NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN. - - - Nan::To() - -### Maybe Types - -The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_. - -* **Maybe Types** - - Nan::MaybeLocal - - Nan::Maybe - - Nan::Nothing - - Nan::Just -* **Maybe Helpers** - - Nan::Call() - - Nan::ToDetailString() - - Nan::ToArrayIndex() - - Nan::Equals() - - Nan::NewInstance() - - Nan::GetFunction() - - Nan::Set() - - Nan::DefineOwnProperty() - - Nan::ForceSet() - - Nan::Get() - - Nan::GetPropertyAttributes() - - Nan::Has() - - Nan::Delete() - - Nan::GetPropertyNames() - - Nan::GetOwnPropertyNames() - - Nan::SetPrototype() - - Nan::ObjectProtoToString() - - Nan::HasOwnProperty() - - Nan::HasRealNamedProperty() - - Nan::HasRealIndexedProperty() - - Nan::HasRealNamedCallbackProperty() - - Nan::GetRealNamedPropertyInPrototypeChain() - - Nan::GetRealNamedProperty() - - Nan::CallAsFunction() - - Nan::CallAsConstructor() - - Nan::GetSourceLine() - - Nan::GetLineNumber() - - Nan::GetStartColumn() - - Nan::GetEndColumn() - - Nan::CloneElementAt() - - Nan::HasPrivate() - - Nan::GetPrivate() - - Nan::SetPrivate() - - Nan::DeletePrivate() - - Nan::MakeMaybe() - -### Script - -NAN provides a `v8::Script` helpers as the API has changed over the supported versions of V8. - - - Nan::CompileScript() - - Nan::RunScript() - - -### JSON - -The _JSON_ object provides the c++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object. - - - Nan::JSON.Parse - - Nan::JSON.Stringify - -Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments. - -### Errors - -NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted. - -Note that an Error object is simply a specialized form of `v8::Value`. - -Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information. - - - Nan::Error() - - Nan::RangeError() - - Nan::ReferenceError() - - Nan::SyntaxError() - - Nan::TypeError() - - Nan::ThrowError() - - Nan::ThrowRangeError() - - Nan::ThrowReferenceError() - - Nan::ThrowSyntaxError() - - Nan::ThrowTypeError() - - Nan::FatalException() - - Nan::ErrnoException() - - Nan::TryCatch - - -### Buffers - -NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility. - - - Nan::NewBuffer() - - Nan::CopyBuffer() - - Nan::FreeCallback() - -### Nan::Callback - -`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution. - - - Nan::Callback - -### Asynchronous work helpers - -`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier. - - - Nan::AsyncWorker - - Nan::AsyncProgressWorkerBase & Nan::AsyncProgressWorker - - Nan::AsyncProgressQueueWorker - - Nan::AsyncQueueWorker - -### Strings & Bytes - -Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node.

Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification. - -If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG.

(Note: brotli is only supported on Node 10.16.0 or above, and will not be requested or processed on earlier versions.) - -```js -needle.get('http://stackoverflow.com/feeds', { compressed: true }, function(err, resp) { - console.log(resp.body); // this little guy won't be a Gzipped binary blob - // but a nice object containing all the latest entries -}); -``` - -Or in anti-callback mode, using a few other options: - -```js -var options = { - compressed : true, // sets 'Accept-Encoding' to 'gzip, deflate, br' - follow_max : 5, // follow up to five redirects - rejectUnauthorized : true // verify SSL certificate -} - -var stream = needle.get('https://backend.server.com/everything.html', options); - -// read the chunks from the 'readable' event, so the stream gets consumed. -stream.on('readable', function() { - while (data = this.read()) { - console.log(data.toString()); - } -}) - -stream.on('done', function(err) { - // if our request had an error, our 'done' event will tell us. - if (!err) console.log('Great success!'); -}) -``` - -API ---- - -### needle(method, url[, data][, options][, callback]) `(> 2.0.x)` - -Calling `needle()` directly returns a Promise. Besides `method` and `url`, all parameters are optional, although when sending a `post`, `put` or `patch` request you will get an error if `data` is not present. - -```js -needle('get', 'http://some.url.com') - .then(function(resp) { console.log(resp.body) }) - .catch(function(err) { console.error(err) }) -}) -``` - -Except from the above, all of Needle's request methods return a Readable stream, and both `options` and `callback` are optional. If passed, the callback will return three arguments: `error`, `response` and `body`, which is basically an alias for `response.body`. - -### needle.head(url[, options][, callback]) - -```js -needle.head('https://my.backend.server.com', { - open_timeout: 5000 // if we're not able to open a connection in 5 seconds, boom. -}, function(err, resp) { - if (err) - console.log('Shoot! Something is wrong: ' + err.message) - else - console.log('Yup, still alive.') -}) -``` - -### needle.get(url[, options][, callback]) - -```js -needle.get('google.com/search?q=syd+barrett', function(err, resp) { - // if no http:// is found, Needle will automagically prepend it. -}); -``` - -### needle.post(url, data[, options][, callback]) - -```js -var options = { - headers: { 'X-Custom-Header': 'Bumbaway atuna' } -} - -needle.post('https://my.app.com/endpoint', 'foo=bar', options, function(err, resp) { - // you can pass params as a string or as an object. -}); -``` - -### needle.put(url, data[, options][, callback]) - -```js -var nested = { - params: { - are: { - also: 'supported' - } - } -} - -needle.put('https://api.app.com/v2', nested, function(err, resp) { - console.log('Got ' + resp.bytes + ' bytes.') // another nice treat from this handsome fella. -}); -``` - -### needle.patch(url, data[, options][, callback]) - -Same behaviour as PUT. - -### needle.delete(url, data[, options][, callback]) - -```js -var options = { - username: 'fidelio', - password: 'x' -} - -needle.delete('https://api.app.com/messages/123', null, options, function(err, resp) { - // in this case, data may be null, but you need to explicity pass it. -}); -``` - -### needle.request(method, url, data[, options][, callback]) - -Generic request. This not only allows for flexibility, but also lets you perform a GET request with data, in which case will be appended to the request as a query string, unless you pass a `json: true` option (read below). - -```js -var params = { - q : 'a very smart query', - page : 2 -} - -needle.request('get', 'forum.com/search', params, function(err, resp) { - if (!err && resp.statusCode == 200) - console.log(resp.body); // here you go, mister. -}); -``` - -Now, if you set pass `json: true` among the options, Needle won't set your params as a querystring but instead send a JSON representation of your data through the request's body, as well as set the `Content-Type` and `Accept` headers to `application/json`. - -```js -needle.request('get', 'forum.com/search', params, { json: true }, function(err, resp) { - if (resp.statusCode == 200) console.log('It worked!'); -}); -``` - -Events ------- - -The [Readable stream](https://nodejs.org/api/stream.html#stream_class_stream_readable) object returned by the above request methods emits the following events, in addition to the regular ones (e.g. `end`, `close`, `data`, `pipe`, `readable`). - -### Event: `'response'` - - - `response ` - -Emitted when the underlying [http.ClientRequest](https://nodejs.org/api/http.html#http_class_http_clientrequest) emits a response event. This is after the connection is established and the header received, but before any of it is processed (e.g. authorization required or redirect to be followed). No data has been consumed at this point. - -### Event: `'redirect'` - - - `location ` - -Indicates that the a redirect is being followed. This means that the response code was a redirect (`301`, `302`, `303`, `307`) and the given [redirect options](#redirect-options) allowed following the URL received in the `Location` header. - -### Event: `'header'` - - - `statusCode ` - - `headers ` - -Triggered after the header has been processed, and just before the data is to be consumed. This implies that no redirect was followed and/or authentication header was received. In other words, we got a "valid" response. - -### Event: `'done'` (previously 'end') - - - `exception ` (optional) - -Emitted when the request/response process has finished, either because all data was consumed or an error ocurred somewhere in between. Unlike a regular stream's `end` event, Needle's `done` will be fired either on success or on failure, which is why the first argument may be an Error object. In other words: - -```js -var resp = needle.get('something.worthy/of/being/streamed/by/needle'); -resp.pipe(someWritableStream); - -resp.on('done', function(err) { - if (err) console.log('An error ocurred: ' + err.message); - else console.log('Great success!'); -}) -``` - -### Event: `'err'` - - - `exception ` - -Emitted when an error ocurrs. This should only happen once in the lifecycle of a Needle request. - -### Event: `'timeout'` - - - `type ` - -Emitted when an timeout error occurs. Type can be either 'open', 'response', or 'read'. This will called right before aborting the request, which will also trigger an `err` event, a described above, with an `ECONNRESET` (Socket hang up) exception. - -Request options ---------------- - -For information about options that've changed, there's always [the changelog](https://github.com/tomas/needle/releases). - - - `agent` : Uses an [http.Agent](https://nodejs.org/api/http.html#http_class_http_agent) of your choice, instead of the global, default one. Useful for tweaking the behaviour at the connection level, such as when doing tunneling (see below for an example). - - `json` : When `true`, sets content type to `application/json` and sends request body as JSON string, instead of a query string. - - `open_timeout`: (or `timeout`) Returns error if connection takes longer than X milisecs to establish. Defaults to `10000` (10 secs). `0` means no timeout. - - `response_timeout`: Returns error if no response headers are received in X milisecs, counting from when the connection is opened. Defaults to `0` (no response timeout). - - `read_timeout`: Returns error if data transfer takes longer than X milisecs, once response headers are received. Defaults to `0` (no timeout). - - `follow_max` : (or `follow`) Number of redirects to follow. Defaults to `0`. See below for more redirect options. - - `multipart` : Enables multipart/form-data encoding. Defaults to `false`. Use it when uploading files. - - `proxy` : Forwards request through HTTP(s) proxy. Eg. `proxy: 'http://user:pass@proxy.server.com:3128'`. For more advanced proxying/tunneling use a custom `agent`, as described below. - - `headers` : Object containing custom HTTP headers for request. Overrides defaults described below. - - `auth` : Determines what to do with provided username/password. Options are `auto`, `digest` or `basic` (default). `auto` will detect the type of authentication depending on the response headers. - - `stream_length`: When sending streams, this lets you manually set the Content-Length header --if the stream's bytecount is known beforehand--, preventing ECONNRESET (socket hang up) errors on some servers that misbehave when receiving payloads of unknown size. Set it to `0` and Needle will get and set the stream's length for you, or leave unset for the default behaviour, which is no Content-Length header for stream payloads. - - `localAddress`: , IP address. Passed to http/https request. Local interface from witch the request should be emitted. - - `uri_modifier`: Anonymous function taking request (or redirect location if following redirects) URI as an argument and modifying it given logic. It has to return a valid URI string for successful request. - -Response options ----------------- - - - `decode_response` : (or `decode`) Whether to decode the text responses to UTF-8, if Content-Type header shows a different charset. Defaults to `true`. - - `parse_response` : (or `parse`) Whether to parse XML or JSON response bodies automagically. Defaults to `true`. You can also set this to 'xml' or 'json' in which case Needle will *only* parse the response if the content type matches. - - `output` : Dump response output to file. This occurs after parsing and charset decoding is done. - - `parse_cookies` : Whether to parse response’s `Set-Cookie` header. Defaults to `true`. If parsed, response cookies will be available at `resp.cookies`. - -HTTP Header options -------------------- - -These are basically shortcuts to the `headers` option described above. - - - `cookies` : Builds and sets a Cookie header from a `{ key: 'value' }` object. - - `compressed`: If `true`, sets 'Accept-Encoding' header to 'gzip,deflate', and inflates content if zipped. Defaults to `false`. - - `username` : For HTTP basic auth. - - `password` : For HTTP basic auth. Requires username to be passed, but is optional. - - `accept` : Sets 'Accept' HTTP header. Defaults to `*/*`. - - `connection`: Sets 'Connection' HTTP header. Not set by default, unless running Node < 0.11.4 in which case it defaults to `close`. More info about this below. - - `user_agent`: Sets the 'User-Agent' HTTP header. Defaults to `Needle/{version} (Node.js {node_version})`. - - `content_type`: Sets the 'Content-Type' header. Unset by default, unless you're sending data in which case it's set accordingly to whatever is being sent (`application/x-www-form-urlencoded`, `application/json` or `multipart/form-data`). That is, of course, unless the option is passed, either here or through `options.headers`. You're the boss. - -Node.js TLS Options -------------------- - -These options are passed directly to `https.request` if present. Taken from the [original documentation](http://nodejs.org/docs/latest/api/https.html): - - - `pfx` : Certificate, Private key and CA certificates to use for SSL. - - `key` : Private key to use for SSL. - - `passphrase` : A string of passphrase for the private key or pfx. - - `cert` : Public x509 certificate to use. - - `ca` : An authority certificate or array of authority certificates to check the remote host against. - - `ciphers` : A string describing the ciphers to use or exclude. - - `rejectUnauthorized` : If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. - - `secureProtocol` : The SSL method to use, e.g. SSLv3_method to force SSL version 3. - - `family` : IP address family to use when resolving host and hostname. Valid values are 4 or 6. When unspecified, both IP v4 and v6 will be used. - -Redirect options ----------------- - -These options only apply if the `follow_max` (or `follow`) option is higher than 0. - - - `follow_set_cookies` : Sends the cookies received in the `set-cookie` header as part of the following request. `false` by default. - - `follow_set_referer` : Sets the 'Referer' header to the requested URI when following a redirect. `false` by default. - - `follow_keep_method` : If enabled, resends the request using the original verb instead of being rewritten to `get` with no data. `false` by default. - - `follow_if_same_host` : When true, Needle will only follow redirects that point to the same host as the original request. `false` by default. - - `follow_if_same_protocol` : When true, Needle will only follow redirects that point to the same protocol as the original request. `false` by default. - - `follow_if_same_location` : Unless true, Needle will not follow redirects that point to same location (as set in the response header) as the original request URL. `false` by default. - -Overriding Defaults -------------------- - -Yes sir, we have it. Needle includes a `defaults()` method, that lets you override some of the defaults for all future requests. Like this: - -```js -needle.defaults({ - open_timeout: 60000, - user_agent: 'MyApp/1.2.3', - parse_response: false }); -``` - -This will override Needle's default user agent and 10-second timeout, and disable response parsing, so you don't need to pass those options in every other request. - -More advanced Proxy support ---------------------------- - -Since you can pass a custom HTTPAgent to Needle you can do all sorts of neat stuff. For example, if you want to use the [`tunnel`](https://github.com/koichik/node-tunnel) module for HTTPS proxying, you can do this: - -```js -var tunnel = require('tunnel'); -var myAgent = tunnel.httpOverHttp({ - proxy: { host: 'localhost' } -}); - -needle.get('foobar.com', { agent: myAgent }); -``` - -Regarding the 'Connection' header ---------------------------------- - -Unless you're running an old version of Node (< 0.11.4), by default Needle won't set the Connection header on requests, yielding Node's default behaviour of keeping the connection alive with the target server. This speeds up immensely the process of sending several requests to the same host. - -On older versions, however, this has the unwanted behaviour of preventing the runtime from exiting, either because of a bug or 'feature' that was changed on 0.11.4. To overcome this Needle does set the 'Connection' header to 'close' on those versions, however this also means that making new requests to the same host doesn't benefit from Keep-Alive. - -So if you're stuck on 0.10 or even lower and want full speed, you can simply set the Connection header to 'Keep-Alive' by using `{ connection: 'Keep-Alive' }`. Please note, though, that an event loop handler will prevent the runtime from exiting so you'll need to manually call `process.exit()` or the universe will collapse. - -Examples Galore ---------------- - -### HTTPS GET with Basic Auth - -```js -needle.get('https://api.server.com', { username: 'you', password: 'secret' }, - function(err, resp) { - // used HTTP auth -}); -``` - -Or use [RFC-1738](http://tools.ietf.org/html/rfc1738#section-3.1) basic auth URL syntax: - -```js -needle.get('https://username:password@api.server.com', function(err, resp) { - // used HTTP auth from URL -}); -``` - -### Digest Auth - -```js -needle.get('other.server.com', { username: 'you', password: 'secret', auth: 'digest' }, - function(err, resp, body) { - // needle prepends 'http://' to your URL, if missing -}); -``` - -### Custom Accept header, deflate - -```js -var options = { - compressed : true, - follow : 10, - accept : 'application/vnd.github.full+json' -} - -needle.get('api.github.com/users/tomas', options, function(err, resp, body) { - // body will contain a JSON.parse(d) object - // if parsing fails, you'll simply get the original body -}); -``` - -### GET XML object - -```js -needle.get('https://news.ycombinator.com/rss', function(err, resp, body) { - // you'll get a nice object containing the nodes in the RSS -}); -``` - -### GET binary, output to file - -```js -needle.get('http://upload.server.com/tux.png', { output: '/tmp/tux.png' }, function(err, resp, body) { - // you can dump any response to a file, not only binaries. -}); -``` - -### GET through proxy - -```js -needle.get('http://search.npmjs.org', { proxy: 'http://localhost:1234' }, function(err, resp, body) { - // request passed through proxy -}); -``` - -### GET a very large document in a stream (from 0.7+) - -```js -var stream = needle.get('http://www.as35662.net/100.log'); - -stream.on('readable', function() { - var chunk; - while (chunk = this.read()) { - console.log('got data: ', chunk); - } -}); -``` - -### GET JSON object in a stream (from 0.7+) - -```js -var stream = needle.get('http://jsonplaceholder.typicode.com/db', { parse: true }); - -stream.on('readable', function() { - var node; - - // our stream will only emit a single JSON root node. - while (node = this.read()) { - console.log('got data: ', node); - } -}); -``` - -### GET JSONStream flexible parser with search query (from 0.7+) - -```js - - // The 'data' element of this stream will be the string representation - // of the titles of all posts. - -needle.get('http://jsonplaceholder.typicode.com/db', { parse: true }) - .pipe(new JSONStream.parse('posts.*.title')); - .on('data', function (obj) { - console.log('got post title: %s', obj); - }); -``` - -### File upload using multipart, passing file path - -```js -var data = { - foo: 'bar', - image: { file: '/home/tomas/linux.png', content_type: 'image/png' } -} - -needle.post('http://my.other.app.com', data, { multipart: true }, function(err, resp, body) { - // needle will read the file and include it in the form-data as binary -}); -``` - -### Stream upload, PUT or POST - -``` js -needle.put('https://api.app.com/v2', fs.createReadStream('myfile.txt'), function(err, resp, body) { - // stream content is uploaded verbatim -}); -``` - -### Multipart POST, passing data buffer - -```js -var buffer = fs.readFileSync('/path/to/package.zip'); - -var data = { - zip_file: { - buffer : buffer, - filename : 'mypackage.zip', - content_type : 'application/octet-stream' - } -} - -needle.post('http://somewhere.com/over/the/rainbow', data, { multipart: true }, function(err, resp, body) { - // if you see, when using buffers we need to pass the filename for the multipart body. - // you can also pass a filename when using the file path method, in case you want to override - // the default filename to be received on the other end. -}); -``` - -### Multipart with custom Content-Type - -```js -var data = { - token: 'verysecret', - payload: { - value: JSON.stringify({ title: 'test', version: 1 }), - content_type: 'application/json' - } -} - -needle.post('http://test.com/', data, { timeout: 5000, multipart: true }, function(err, resp, body) { - // in this case, if the request takes more than 5 seconds - // the callback will return a [Socket closed] error -}); -``` - -For even more examples, check out the examples directory in the repo. - -### Testing - -To run tests, you need to generate a self-signed SSL certificate in the `test` directory.

Valid values are `linux`, `darwin`, `win32`, `sunos`, `freebsd`, `openbsd`, and `aix`. - -Both `--build-from-source` and `--fallback-to-build` can be passed alone or they can provide values. You can pass `--fallback-to-build=false` to override the option as declared in package.json. In addition to being able to pass `--build-from-source` you can also pass `--build-from-source=myapp` where `myapp` is the name of your module. - -For example: `npm install --build-from-source=myapp`. This is useful if: - - - `myapp` is referenced in the package.json of a larger app and therefore `myapp` is being installed as a dependency with `npm install`. - - The larger app also depends on other modules installed with `node-pre-gyp` - - You only want to trigger a source compile for `myapp` and the other modules. - -### Configuring - -This is a guide to configuring your module to use node-pre-gyp. - -#### 1) Add new entries to your `package.json` - - - Add `node-pre-gyp` to `dependencies` - - Add `aws-sdk` as a `devDependency` - - Add a custom `install` script - - Declare a `binary` object - -This looks like: - -```js - "dependencies" : { - "node-pre-gyp": "0.6.x" - }, - "devDependencies": { - "aws-sdk": "2.x" - } - "scripts": { - "install": "node-pre-gyp install --fallback-to-build" - }, - "binary": { - "module_name": "your_module", - "module_path": "./lib/binding/", - "host": "https://your_module.s3-us-west-1.amazonaws.com" - } -``` - -For a full example see [node-addon-examples's package.json](https://github.com/springmeyer/node-addon-example/blob/master/package.json). - -Let's break this down: - - - Dependencies need to list `node-pre-gyp` - - Your devDependencies should list `aws-sdk` so that you can run `node-pre-gyp publish` locally or a CI system. We recommend using `devDependencies` only since `aws-sdk` is large and not needed for `node-pre-gyp install` since it only uses http to fetch binaries - - Your `scripts` section should override the `install` target with `"install": "node-pre-gyp install --fallback-to-build"`. This allows node-pre-gyp to be used instead of the default npm behavior of always source compiling with `node-gyp` directly. - - Your package.json should contain a `binary` section describing key properties you provide to allow node-pre-gyp to package optimally. They are detailed below. - -Note: in the past we recommended putting `node-pre-gyp` in the `bundledDependencies`, but we no longer recommend this. In the past there were npm bugs (with node versions 0.10.x) that could lead to node-pre-gyp not being available at the right time during install (unless we bundled). This should no longer be the case. Also, for a time we recommended using `"preinstall": "npm install node-pre-gyp"` as an alternative method to avoid needing to bundle. But this did not behave predictably across all npm versions - see https://github.com/mapbox/node-pre-gyp/issues/260 for the details. So we do not recommend using `preinstall` to install `node-pre-gyp`. More history on this at https://github.com/strongloop/fsevents/issues/157#issuecomment-265545908. - -##### The `binary` object has three required properties - -###### module_name - -The name of your native node module. This value must: - - - Match the name passed to [the NODE_MODULE macro](http://nodejs.org/api/addons.html#addons_hello_world) - - Must be a valid C variable name (e.g. it cannot contain `-`) - - Should not include the `.node` extension. - -###### module_path - -The location your native module is placed after a build. This should be an empty directory without other Javascript files. This entire directory will be packaged in the binary tarball. When installing from a remote package this directory will be overwritten with the contents of the tarball. - -Note: This property supports variables based on [Versioning](#versioning). - -###### host - -A url to the remote location where you've published tarball binaries (must be `https` not `http`). - -It is highly recommended that you use Amazon S3. The reasons are: - - - Various node-pre-gyp commands like `publish` and `info` only work with an S3 host. - - S3 is a very solid hosting platform for distributing large files. - - We provide detail documentation for using [S3 hosting](#s3-hosting) with node-pre-gyp. - -Why then not require S3? Because while some applications using node-pre-gyp need to distribute binaries as large as 20-30 MB, others might have very small binaries and might wish to store them in a GitHub repo. This is not recommended, but if an author really wants to host in a non-S3 location then it should be possible. - -It should also be mentioned that there is an optional and entirely separate npm module called [node-pre-gyp-github](https://github.com/bchr02/node-pre-gyp-github) which is intended to complement node-pre-gyp and be installed along with it. It provides the ability to store and publish your binaries within your repositories GitHub Releases if you would rather not use S3 directly. Installation and usage instructions can be found [here](https://github.com/bchr02/node-pre-gyp-github), but the basic premise is that instead of using the ```node-pre-gyp publish``` command you would use ```node-pre-gyp-github publish```. - -##### The `binary` object has two optional properties - -###### remote_path - -It **is recommended** that you customize this property. This is an extra path to use for publishing and finding remote tarballs. The default value for `remote_path` is `""` meaning that if you do not provide it then all packages will be published at the base of the `host`. It is recommended to provide a value like `./{name}/v{version}` to help organize remote packages in the case that you choose to publish multiple node addons to the same `host`. - -Note: This property supports variables based on [Versioning](#versioning). - -###### package_name - -It is **not recommended** to override this property unless you are also overriding the `remote_path`. This is the versioned name of the remote tarball containing the binary `.node` module and any supporting files you've placed inside the `module_path` directory. Unless you specify `package_name` in your `package.json` then it defaults to `{module_name}-v{version}-{node_abi}-{platform}-{arch}.tar.gz` which allows your binary to work across node versions, platforms, and architectures. If you are using `remote_path` that is also versioned by `./{module_name}/v{version}` then you could remove these variables from the `package_name` and just use: `{node_abi}-{platform}-{arch}.tar.gz`. Then your remote tarball will be looked up at, for example, `https://example.com/your-module/v0.1.0/node-v11-linux-x64.tar.gz`. - -Avoiding the version of your module in the `package_name` and instead only embedding in a directory name can be useful when you want to make a quick tag of your module that does not change any C++ code. In this case you can just copy binaries to the new version behind the scenes like: - -```sh -aws s3 sync --acl public-read s3://mapbox-node-binary/sqlite3/v3.0.3/ s3://mapbox-node-binary/sqlite3/v3.0.4/ -``` - -Note: This property supports variables based on [Versioning](#versioning). - -#### 2) Add a new target to binding.gyp - -`node-pre-gyp` calls out to `node-gyp` to compile the module and passes variables along like [module_name](#module_name) and [module_path](#module_path). - -A new target must be added to `binding.gyp` that moves the compiled `.node` module from `./build/Release/module_name.node` into the directory specified by `module_path`. - -Add a target like this at the end of your `targets` list: - -```js - { - "target_name": "action_after_build", - "type": "none", - "dependencies": [ "<(module_name)" ], - "copies": [ - { - "files": [ "<(PRODUCT_DIR)/<(module_name).node" ], - "destination": "<(module_path)" - } - ] - } -``` - -For a full example see [node-addon-example's binding.gyp](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/binding.gyp). - -#### 3) Dynamically require your `.node` - -Inside the main js file that requires your addon module you are likely currently doing: - -```js -var binding = require('../build/Release/binding.node'); -``` - -or: - -```js -var bindings = require('./bindings') -``` - -Change those lines to: - -```js -var binary = require('node-pre-gyp'); -var path = require('path'); -var binding_path = binary.find(path.resolve(path.join(__dirname,'./package.json'))); -var binding = require(binding_path); -``` - -For a full example see [node-addon-example's index.js](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/index.js#L1-L4) - -#### 4) Build and package your app - -Now build your module from source: - - npm install --build-from-source - -The `--build-from-source` tells `node-pre-gyp` to not look for a remote package and instead dispatch to node-gyp to build. - -Now `node-pre-gyp` should now also be installed as a local dependency so the command line tool it offers can be found at `./node_modules/.bin/node-pre-gyp`. - -#### 5) Test - -Now `npm test` should work just as it did before. - -#### 6) Publish the tarball - -Then package your app: - - ./node_modules/.bin/node-pre-gyp package - -Once packaged, now you can publish: - - ./node_modules/.bin/node-pre-gyp publish - -Currently the `publish` command pushes your binary to S3. This requires: - - - You have installed `aws-sdk` with `npm install aws-sdk` - - You have created a bucket already. - - The `host` points to an S3 http or https endpoint. - - You have configured node-pre-gyp to read your S3 credentials (see [S3 hosting](#s3-hosting) for details). - -You can also host your binaries elsewhere. To do this requires: - - - You manually publish the binary created by the `package` command to an `https` endpoint - - Ensure that the `host` value points to your custom `https` endpoint. - -#### 7) Automate builds - -Now you need to publish builds for all the platforms and node versions you wish to support. This is best automated. - - - See [Appveyor Automation](#appveyor-automation) for how to auto-publish builds on Windows. - - See [Travis Automation](#travis-automation) for how to auto-publish builds on OS X and Linux. - -#### 8) You're done! - -Now publish your module to the npm registry. Users will now be able to install your module from a binary. - -What will happen is this: - -1. `npm install ` will pull from the npm registry -2. npm will run the `install` script which will call out to `node-pre-gyp` -3. `node-pre-gyp` will fetch the binary `.node` module and unpack in the right place -4. Assuming that all worked, you are done - -If a a binary was not available for a given platform and `--fallback-to-build` was used then `node-gyp rebuild` will be called to try to source compile the module. - -## N-API Considerations - -[N-API](https://nodejs.org/api/n-api.html#n_api_n_api) is an ABI-stable alternative to previous technologies such as [nan](https://github.com/nodejs/nan) which are tied to a specific Node runtime engine. N-API is Node runtime engine agnostic and guarantees modules created today will continue to run, without changes, into the future. - -Using `node-pre-gyp` with N-API projects requires a handful of additional configuration values and imposes some additional requirements. - -The most significant difference is that an N-API module can be coded to target multiple N-API versions. Therefore, an N-API module must declare in its `package.json` file which N-API versions the module is designed to run against. In addition, since multiple builds may be required for a single module, path and file names must be specified in way that avoids naming conflicts. - -### The `napi_versions` array property - -An N-API modules must declare in its `package.json` file, the N-API versions the module is intended to support. This is accomplished by including an `napi-versions` array property in the `binary` object. For example: - -```js -"binary": { - "module_name": "your_module", - "module_path": "your_module_path", - "host": "https://your_bucket.s3-us-west-1.amazonaws.com", - "napi_versions": [1,3] - } -``` - -If the `napi_versions` array property is *not* present, `node-pre-gyp` operates as it always has. Including the `napi_versions` array property instructs `node-pre-gyp` that this is a N-API module build. - -When the `napi_versions` array property is present, `node-pre-gyp` fires off multiple operations, one for each of the N-API versions in the array. In the example above, two operations are initiated, one for N-API version 1 and second for N-API version 3. How this version number is communicated is described next. - -### The `napi_build_version` value - -For each of the N-API module operations `node-pre-gyp` initiates, it ensures that the `napi_build_version` is set appropriately. - -This value is of importance in two areas: - -1. The C/C++ code which needs to know against which N-API version it should compile. -2. `node-pre-gyp` itself which must assign appropriate path and file names to avoid collisions. - -### Defining `NAPI_VERSION` for the C/C++ code - -The `napi_build_version` value is communicated to the C/C++ code by adding this code to the `binding.gyp` file: - -``` -"defines": [ - "NAPI_VERSION=<(napi_build_version)", -] -``` - -This ensures that `NAPI_VERSION`, an integer value, is declared appropriately to the C/C++ code for each build. - -> Note that earlier versions of this document recommended defining the symbol `NAPI_BUILD_VERSION`. `NAPI_VERSION` is prefered because it used by the N-API C/C++ headers to configure the specific N-API veriosn being requested. - -### Path and file naming requirements in `package.json` - -Since `node-pre-gyp` fires off multiple operations for each request, it is essential that path and file names be created in such a way as to avoid collisions. This is accomplished by imposing additional path and file naming requirements. - -Specifically, when performing N-API builds, the `{napi_build_version}` text configuration value *must* be present in the `module_path` property. In addition, the `{napi_build_version}` text configuration value *must* be present in either the `remote_path` or `package_name` property. (No problem if it's in both.) - -Here's an example: - -```js -"binary": { - "module_name": "your_module", - "module_path": "./lib/binding/napi-v{napi_build_version}", - "remote_path": "./{module_name}/v{version}/{configuration}/", - "package_name": "{platform}-{arch}-napi-v{napi_build_version}.tar.gz", - "host": "https://your_bucket.s3-us-west-1.amazonaws.com", - "napi_versions": [1,3] - } -``` - -## Supporting both N-API and NAN builds - -You may have a legacy native add-on that you wish to continue supporting for those versions of Node that do not support N-API, as you add N-API support for later Node versions. This can be accomplished by specifying the `node_napi_label` configuration value in the package.json `binary.package_name` property. - -Placing the configuration value `node_napi_label` in the package.json `binary.package_name` property instructs `node-pre-gyp` to build all viable N-API binaries supported by the current Node instance. If the current Node instance does not support N-API, `node-pre-gyp` will request a traditional, non-N-API build. - -The configuration value `node_napi_label` is set by `node-pre-gyp` to the type of build created, `napi` or `node`, and the version number. For N-API builds, the string contains the N-API version nad has values like `napi-v3`. For traditional, non-N-API builds, the string contains the ABI version with values like `node-v46`. - -Here's how the `binary` configuration above might be changed to support both N-API and NAN builds: - -```js -"binary": { - "module_name": "your_module", - "module_path": "./lib/binding/{node_napi_label}", - "remote_path": "./{module_name}/v{version}/{configuration}/", - "package_name": "{platform}-{arch}-{node_napi_label}.tar.gz", - "host": "https://your_bucket.s3-us-west-1.amazonaws.com", - "napi_versions": [1,3] - } -``` - -The C/C++ symbol `NAPI_VERSION` can be used to distinguish N-API and non-N-API builds. The value of `NAPI_VERSION` is set to the integer N-API version for N-API builds and is set to `0` for non-N-API builds. - -For example: - -```C -#if NAPI_VERSION -// N-API code goes here -#else -// NAN code goes here -#endif -``` - -### Two additional configuration values - -The following two configuration values, which were implemented in previous versions of `node-pre-gyp`, continue to exist, but have been replaced by the `node_napi_label` configuration value described above. - -1. `napi_version` If N-API is supported by the currently executing Node instance, this value is the N-API version number supported by Node. If N-API is not supported, this value is an empty string. - -2. `node_abi_napi` If the value returned for `napi_version` is non empty, this value is `'napi'`. If the value returned for `napi_version` is empty, this value is the value returned for `node_abi`. - -These values are present for use in the `binding.gyp` file and may be used as `{napi_version}` and `{node_abi_napi}` for text substituion in the `binary` properties of the `package.json` file. - -## S3 Hosting - -You can host wherever you choose but S3 is cheap, `node-pre-gyp publish` expects it, and S3 can be integrated well with [Travis.ci](http://travis-ci.org) to automate builds for OS X and Ubuntu, and with [Appveyor](http://appveyor.com) to automate builds for Windows. Here is an approach to do this: - -First, get setup locally and test the workflow: - -#### 1) Create an S3 bucket - -And have your **key** and **secret key** ready for writing to the bucket. - -It is recommended to create a IAM user with a policy that only gives permissions to the specific bucket you plan to publish to. This can be done in the [IAM console](https://console.aws.amazon.com/iam/) by: 1) adding a new user, 2) choosing `Attach User Policy`, 3) Using the `Policy Generator`, 4) selecting `Amazon S3` for the service, 5) adding the actions: `DeleteObject`, `GetObject`, `GetObjectAcl`, `ListBucket`, `PutObject`, `PutObjectAcl`, 6) adding an ARN of `arn:aws:s3:::bucket/*` (replacing `bucket` with your bucket name), and finally 7) clicking `Add Statement` and saving the policy. It should generate a policy like: - -```js -{ - "Version": "2012-10-17", - "Statement": [ - { - "Sid": "Stmt1394587197000", - "Effect": "Allow", - "Action": [ - "s3:DeleteObject", - "s3:GetObject", - "s3:GetObjectAcl", - "s3:ListBucket", - "s3:PutObject", - "s3:PutObjectAcl" - ], - "Resource": [ - "arn:aws:s3:::node-pre-gyp-tests/*" - ] - } - ] -} -``` - -#### 2) Install node-pre-gyp - -Either install it globally: - - npm install node-pre-gyp -g - -Or put the local version on your PATH - - export PATH=`pwd`/node_modules/.bin/:$PATH - -#### 3) Configure AWS credentials - -There are several ways to do this. - -You can use any of the methods described at http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/node-configuring.html. - -Or you can create a `~/.node_pre_gyprc` - -Or pass options in any way supported by [RC](https://github.com/dominictarr/rc#standards) - -A `~/.node_pre_gyprc` looks like: - -```js -{ - "accessKeyId": "xxx", - "secretAccessKey": "xxx" -} -``` - -Another way is to use your environment: - - export node_pre_gyp_accessKeyId=xxx - export node_pre_gyp_secretAccessKey=xxx - -You may also need to specify the `region` if it is not explicit in the `host` value you use. The `bucket` can also be specified but it is optional because `node-pre-gyp` will detect it from the `host` value. - -#### 4) Package and publish your build - -Install the `aws-sdk`: - - npm install aws-sdk - -Then publish: - - node-pre-gyp package publish - -Note: if you hit an error like `Hostname/IP doesn't match certificate's altnames` it may mean that you need to provide the `region` option in your config. - -## Appveyor Automation - -[Appveyor](http://www.appveyor.com/) can build binaries and publish the results per commit and supports: - - - Windows Visual Studio 2013 and related compilers - - Both 64 bit (x64) and 32 bit (x86) build configurations - - Multiple Node.js versions - -For an example of doing this see [node-sqlite3's appveyor.yml](https://github.com/mapbox/node-sqlite3/blob/master/appveyor.yml). - -Below is a guide to getting set up: - -#### 1) Create a free Appveyor account - -Go to https://ci.appveyor.com/signup/free and sign in with your GitHub account. - -#### 2) Create a new project - -Go to https://ci.appveyor.com/projects/new and select the GitHub repo for your module - -#### 3) Add appveyor.yml and push it - -Once you have committed an `appveyor.yml` ([appveyor.yml reference](http://www.appveyor.com/docs/appveyor-yml)) to your GitHub repo and pushed it AppVeyor should automatically start building your project. - -#### 4) Create secure variables - -Encrypt your S3 AWS keys by going to and hitting the `encrypt` button. - -Then paste the result into your `appveyor.yml` - -```yml -environment: - node_pre_gyp_accessKeyId: - secure: Dn9HKdLNYvDgPdQOzRq/DqZ/MPhjknRHB1o+/lVU8MA= - node_pre_gyp_secretAccessKey: - secure: W1rwNoSnOku1r+28gnoufO8UA8iWADmL1LiiwH9IOkIVhDTNGdGPJqAlLjNqwLnL -``` - -NOTE: keys are per account but not per repo (this is difference than Travis where keys are per repo but not related to the account used to encrypt them). - -#### 5) Hook up publishing - -Just put `node-pre-gyp package publish` in your `appveyor.yml` after `npm install`. - -#### 6) Publish when you want - -You might wish to publish binaries only on a specific commit. To do this you could borrow from the [Travis CI idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`: - - SET CM=%APPVEYOR_REPO_COMMIT_MESSAGE% - if not "%CM%" == "%CM:[publish binary]=%" node-pre-gyp --msvs_version=2013 publish - -If your commit message contains special characters (e.g. `&`) this method might fail. An alternative is to use PowerShell, which gives you additional possibilities, like ignoring case by using `ToLower()`: - - ps: if($env:APPVEYOR_REPO_COMMIT_MESSAGE.ToLower().Contains('[publish binary]')) { node-pre-gyp --msvs_version=2013 publish } - -Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package. - -## Travis Automation - -[Travis](https://travis-ci.org/) can push to S3 after a successful build and supports both: - - - Ubuntu Precise and OS X (64 bit) - - Multiple Node.js versions - -For an example of doing this see [node-add-example's .travis.yml](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/.travis.yml). - -Note: if you need 32 bit binaries, this can be done from a 64 bit Travis machine. See [the node-sqlite3 scripts for an example of doing this](https://github.com/mapbox/node-sqlite3/blob/bae122aa6a2b8a45f6b717fab24e207740e32b5d/scripts/build_against_node.sh#L54-L74). - -Below is a guide to getting set up: - -#### 1) Install the Travis gem - - gem install travis - -#### 2) Create secure variables - -Make sure you run this command from within the directory of your module. - -Use `travis-encrypt` like: - - travis encrypt node_pre_gyp_accessKeyId=${node_pre_gyp_accessKeyId} - travis encrypt node_pre_gyp_secretAccessKey=${node_pre_gyp_secretAccessKey} - -Then put those values in your `.travis.yml` like: - -```yaml -env: - global: - - secure: F+sEL/v56CzHqmCSSES4pEyC9NeQlkoR0Gs/ZuZxX1ytrj8SKtp3MKqBj7zhIclSdXBz4Ev966Da5ctmcTd410p0b240MV6BVOkLUtkjZJyErMBOkeb8n8yVfSoeMx8RiIhBmIvEn+rlQq+bSFis61/JkE9rxsjkGRZi14hHr4M= - - secure: o2nkUQIiABD139XS6L8pxq3XO5gch27hvm/gOdV+dzNKc/s2KomVPWcOyXNxtJGhtecAkABzaW8KHDDi5QL1kNEFx6BxFVMLO8rjFPsMVaBG9Ks6JiDQkkmrGNcnVdxI/6EKTLHTH5WLsz8+J7caDBzvKbEfTux5EamEhxIWgrI= -``` - -More details on Travis encryption at http://about.travis-ci.org/docs/user/encryption-keys/. - -#### 3) Hook up publishing - -Just put `node-pre-gyp package publish` in your `.travis.yml` after `npm install`. - -##### OS X publishing - -If you want binaries for OS X in addition to linux you can enable [multi-os for Travis](http://docs.travis-ci.com/user/multi-os/#Setting-.travis.yml) - -Use a configuration like: - -```yml - -language: cpp - -os: -- linux -- osx - -env: - matrix: - - NODE_VERSION="4" - - NODE_VERSION="6" - -before_install: -- rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm -- source ~/.nvm/nvm.sh -- nvm install $NODE_VERSION -- nvm use $NODE_VERSION -``` - -See [Travis OS X Gotchas](#travis-os-x-gotchas) for why we replace `language: node_js` and `node_js:` sections with `language: cpp` and a custom matrix. - -Also create platform specific sections for any deps that need install. For example if you need libpng: - -```yml -- if [ $(uname -s) == 'Linux' ]; then apt-get install libpng-dev; fi; -- if [ $(uname -s) == 'Darwin' ]; then brew install libpng; fi; -``` - -For detailed multi-OS examples see [node-mapnik](https://github.com/mapnik/node-mapnik/blob/master/.travis.yml) and [node-sqlite3](https://github.com/mapbox/node-sqlite3/blob/master/.travis.yml). - -##### Travis OS X Gotchas - -First, unlike the Travis Linux machines, the OS X machines do not put `node-pre-gyp` on PATH by default. To do so you will need to: - -```sh -export PATH=$(pwd)/node_modules/.bin:${PATH} -``` - -Second, the OS X machines do not support using a matrix for installing different Node.js versions. So you need to bootstrap the installation of Node.js in a cross platform way. - -By doing: - -```yml -env: - matrix: - - NODE_VERSION="4" - - NODE_VERSION="6" - -before_install: - - rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm - - source ~/.nvm/nvm.sh - - nvm install $NODE_VERSION - - nvm use $NODE_VERSION -``` - -You can easily recreate the previous behavior of this matrix: - -```yml -node_js: - - "4" - - "6" -``` - -#### 4) Publish when you want - -You might wish to publish binaries only on a specific commit. To do this you could borrow from the [Travis CI idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`: - - COMMIT_MESSAGE=$(git log --format=%B --no-merges -n 1 | tr -d '\n') - if [[ ${COMMIT_MESSAGE} =~ "[publish binary]" ]]; then node-pre-gyp publish; fi; - -Then you can trigger new binaries to be built like: - - git commit -a -m "[publish binary]" - -Or, if you don't have any changes to make simply run: - - git commit --allow-empty -m "[publish binary]" - -WARNING: if you are working in a pull request and publishing binaries from there then you will want to avoid double publishing when Travis CI builds both the `push` and `pr`. You only want to run the publish on the `push` commit. See https://github.com/Project-OSRM/node-osrm/blob/8eb837abe2e2e30e595093d16e5354bc5c573575/scripts/is_pr_merge.sh which is called from https://github.com/Project-OSRM/node-osrm/blob/8eb837abe2e2e30e595093d16e5354bc5c573575/scripts/publish.sh for an example of how to do this. - -Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package. To automate the publishing of your entire package to npm on Travis see http://about.travis-ci.org/docs/user/deployment/npm/ - -# Versioning - -The `binary` properties of `module_path`, `remote_path`, and `package_name` support variable substitution. The strings are evaluated by `node-pre-gyp` depending on your system and any custom build flags you passed. - - - `node_abi`: The node C++ `ABI` number. This value is available in Javascript as `process.versions.modules` as of [`>= v0.10.4 >= v0.11.7`](https://github.com/joyent/node/commit/ccabd4a6fa8a6eb79d29bc3bbe9fe2b6531c2d8e) and in C++ as the `NODE_MODULE_VERSION` define much earlier. For versions of Node before this was available we fallback to the V8 major and minor version. - - `platform` matches node's `process.platform` like `linux`, `darwin`, and `win32` unless the user passed the `--target_platform` option to override. - - `arch` matches node's `process.arch` like `x64` or `ia32` unless the user passes the `--target_arch` option to override. - - `libc` matches `require('detect-libc').family` like `glibc` or `musl` unless the user passes the `--target_libc` option to override. - - `configuration` - Either 'Release' or 'Debug' depending on if `--debug` is passed during the build. - - `module_name` - the `binary.module_name` attribute from `package.json`. - - `version` - the semver `version` value for your module from `package.json` (NOTE: ignores the `semver.build` property). - - `major`, `minor`, `patch`, and `prelease` match the individual semver values for your module's `version` - - `build` - the sevmer `build` value. For example it would be `this.that` if your package.json `version` was `v1.0.0+this.that` - - `prerelease` - the semver `prerelease` value.

The Right Way, and the Wrong Way. - -The Wrong Way is to sit down and write an option parser. We've all done -that. - -The Right Way is to write some complex configurable program with so many -options that you hit the limit of your frustration just trying to -manage them all, and defer it with duct-tape solutions until you see -exactly to the core of the problem, and finally snap and write an -awesome option parser. - -If you want to write an option parser, don't write an option parser. -Write a package manager, or a source control system, or a service -restarter, or an operating system. You probably won't end up with a -good one of those, but if you don't give up, and you are relentless and -diligent enough in your procrastination, you may just end up with a very -nice option parser. - -## USAGE - -```javascript -// my-program.js -var nopt = require("nopt") - , Stream = require("stream").Stream - , path = require("path") - , knownOpts = { "foo" : [String, null] - , "bar" : [Stream, Number] - , "baz" : path - , "bloo" : [ "big", "medium", "small" ] - , "flag" : Boolean - , "pick" : Boolean - , "many1" : [String, Array] - , "many2" : [path, Array] - } - , shortHands = { "foofoo" : ["--foo", "Mr. Foo"] - , "b7" : ["--bar", "7"] - , "m" : ["--bloo", "medium"] - , "p" : ["--pick"] - , "f" : ["--flag"] - } - // everything is optional. - // knownOpts and shorthands default to {} - // arg list defaults to process.argv - // slice defaults to 2 - , parsed = nopt(knownOpts, shortHands, process.argv, 2) -console.log(parsed) -``` - -This would give you support for any of the following: - -```console -$ node my-program.js --foo "blerp" --no-flag -{ "foo" : "blerp", "flag" : false } - -$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag -{ bar: 7, foo: "Mr. Hand", flag: true } - -$ node my-program.js --foo "blerp" -f -----p -{ foo: "blerp", flag: true, pick: true } - -$ node my-program.js -fp --foofoo -{ foo: "Mr. Foo", flag: true, pick: true } - -$ node my-program.js --foofoo -- -fp # -- stops the flag parsing. -{ foo: "Mr. Foo", argv: { remain: ["-fp"] } } - -$ node my-program.js --blatzk -fp # unknown opts are ok. -{ blatzk: true, flag: true, pick: true } - -$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value -{ blatzk: 1000, flag: true, pick: true } - -$ node my-program.js --no-blatzk -fp # unless they start with "no-" -{ blatzk: false, flag: true, pick: true } - -$ node my-program.js --baz b/a/z # known paths are resolved. -{ baz: "/Users/isaacs/b/a/z" } - -# if Array is one of the types, then it can take many -# values, and will always be an array.

No parsing is done. -* path: A file system path. Gets resolved against cwd if not absolute. -* url: A url. If it doesn't parse, it isn't accepted. -* Number: Must be numeric. -* Date: Must parse as a date. If it does, and `Date` is one of the options, - then it will return a Date object, not a string. -* Boolean: Must be either `true` or `false`. If an option is a boolean, - then it does not need a value, and its presence will imply `true` as - the value. To negate boolean flags, do `--no-whatever` or `--whatever - false` -* NaN: Means that the option is strictly not allowed. Any value will - fail. -* Stream: An object matching the "Stream" class in node. Valuable - for use when validating programmatically. (npm uses this to let you - supply any WriteStream on the `outfd` and `logfd` config options.) -* Array: If `Array` is specified as one of the types, then the value - will be parsed as a list of options. This means that multiple values - can be specified, and that the value will always be an array. - -If a type is an array of values not on this list, then those are -considered valid values. For instance, in the example above, the -`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`, -and any other value will be rejected. - -When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be -interpreted as their JavaScript equivalents. - -You can also mix types and values, or multiple types, in a list. For -instance `{ blah: [Number, null] }` would allow a value to be set to -either a Number or null. When types are ordered, this implies a -preference, and the first type that can be used to properly interpret -the value will be used. - -To define a new type, add it to `nopt.typeDefs`. Each item in that -hash is an object with a `type` member and a `validate` method. The -`type` member is an object that matches what goes in the type list. The -`validate` method is a function that gets called with `validate(data, -key, val)`. Validate methods should assign `data[key]` to the valid -value of `val` if it can be handled properly, or return boolean -`false` if it cannot. - -You can also call `nopt.clean(data, types, typeDefs)` to clean up a -config object and remove its invalid properties. - -## Error Handling - -By default, nopt outputs a warning to standard error when invalid values for -known options are found. You can change this behavior by assigning a method -to `nopt.invalidHandler`. This method will be called with -the offending `nopt.invalidHandler(key, val, types)`. - -If no `nopt.invalidHandler` is assigned, then it will console.error -its whining. If it is assigned to boolean `false` then the warning is -suppressed. - -## Abbreviations - -Yes, they are supported. If you define options like this: - -```javascript -{ "foolhardyelephants" : Boolean -, "pileofmonkeys" : Boolean } -``` - -Then this will work: - -```bash -node program.js --foolhar --pil -node program.js --no-f --pileofmon -# etc. -``` - -## Shorthands - -Shorthands are a hash of shorter option names to a snippet of args that -they expand to. - -If multiple one-character shorthands are all combined, and the -combination does not unambiguously match any other option or shorthand, -then they will be broken up into their constituent parts. For example: - -```json -{ "s" : ["--loglevel", "silent"] -, "g" : "--global" -, "f" : "--force" -, "p" : "--parseable" -, "l" : "--long" -} -``` - -```bash -npm ls -sgflp -# just like doing this: -npm ls --loglevel silent --global --force --long --parseable -``` - -## The Rest of the args - -The config object returned by nopt is given a special member called -`argv`, which is an object with the following fields: - -* `remain`: The remaining args after all the parsing has occurred. -* `original`: The args as they originally appeared. -* `cooked`: The args after flags and shorthands are expanded. - -## Slicing - -Node programs are called with more or less the exact argv as it appears -in C land, after the v8 and node-specific options have been plucked off. -As such, `argv[0]` is always `node` and `argv[1]` is always the -JavaScript program being run. - -That's usually not very useful to you. So they're sliced off by -default. If you want them, then you can pass in `0` as the last -argument, or any other number that you'd like to slice off the start of -the list. diff --git a/node_modules/nopt/bin/nopt.js b/node_modules/nopt/bin/nopt.js deleted file mode 100755 index 3232d4c..0000000 --- a/node_modules/nopt/bin/nopt.js +++ /dev/null @@ -1,54 +0,0 @@ -#!/usr/bin/env node -var nopt = require("../lib/nopt") - , path = require("path") - , types = { num: Number - , bool: Boolean - , help: Boolean - , list: Array - , "num-list": [Number, Array] - , "str-list": [String, Array] - , "bool-list": [Boolean, Array] - , str: String - , clear: Boolean - , config: Boolean - , length: Number - , file: path - } - , shorthands = { s: [ "--str", "astring" ] - , b: [ "--bool" ] - , nb: [ "--no-bool" ] - , tft: [ "--bool-list", "--no-bool-list", "--bool-list", "true" ] - , "?": ["--help"] - , h: ["--help"] - , H: ["--help"] - , n: [ "--num", "125" ] - , c: ["--config"] - , l: ["--length"] - , f: ["--file"] - } - , parsed = nopt( types - , shorthands - , process.argv - , 2 ) - -console.log("parsed", parsed) - -if (parsed.help) { - console.log("") - console.log("nopt cli tester") - console.log("") - console.log("types") - console.log(Object.keys(types).map(function M (t) { - var type = types[t] - if (Array.isArray(type)) { - return [t, type.map(function (type) { return type.name })] - } - return [t, type && type.name] - }).reduce(function (s, i) { - s[i[0]] = i[1] - return s - }, {})) - console.log("") - console.log("shorthands") - console.log(shorthands) -} diff --git a/node_modules/nopt/lib/nopt.js b/node_modules/nopt/lib/nopt.js deleted file mode 100644 index 0ec5753..0000000 --- a/node_modules/nopt/lib/nopt.js +++ /dev/null @@ -1,441 +0,0 @@ -// info about each config option. - -var debug = process.env.DEBUG_NOPT || process.env.NOPT_DEBUG - ?

(See below) - -## log.heading - -* {String} Default: "" - -If set, a heading that is printed at the start of every line. - -## log.stream - -* {Stream} Default: `process.stderr` - -The stream where output is written. - -## log.enableColor() - -Force colors to be used on all messages, regardless of the output -stream. - -## log.disableColor() - -Disable colors on all messages. - -## log.enableProgress() - -Enable the display of log activity spinner and progress bar - -## log.disableProgress() - -Disable the display of a progress bar - -## log.enableUnicode() - -Force the unicode theme to be used for the progress bar. - -## log.disableUnicode() - -Disable the use of unicode in the progress bar. - -## log.setGaugeTemplate(template) - -Set a template for outputting the progress bar. See the [gauge documentation] for details. - -[gauge documentation]: https://npmjs.com/package/gauge - -## log.setGaugeThemeset(themes) - -Select a themeset to pick themes from for the progress bar. See the [gauge documentation] for details. - -## log.pause() - -Stop emitting messages to the stream, but do not drop them. - -## log.resume() - -Emit all buffered messages that were written while paused. - -## log.log(level, prefix, message, ...) - -* `level` {String} The level to emit the message at -* `prefix` {String} A string prefix. Set to "" to skip. -* `message...` Arguments to `util.format` - -Emit a log message at the specified level. - -## log\[level](prefix, message, ...) - -For example, - -* log.silly(prefix, message, ...) -* log.verbose(prefix, message, ...) -* log.info(prefix, message, ...) -* log.http(prefix, message, ...) -* log.warn(prefix, message, ...) -* log.error(prefix, message, ...) - -Like `log.log(level, prefix, message, ...)`. In this way, each level is -given a shorthand, so you can do `log.info(prefix, message)`. - -## log.addLevel(level, n, style, disp) - -* `level` {String} Level indicator -* `n` {Number} The numeric level -* `style` {Object} Object with fg, bg, inverse, etc. -* `disp` {String} Optional replacement for `level` in the output. - -Sets up a new level with a shorthand function and so forth. - -Note that if the number is `Infinity`, then setting the level to that -will cause all log messages to be suppressed. If the number is -`-Infinity`, then the only way to show it is to enable all log messages. - -## log.newItem(name, todo, weight) - -* `name` {String} Optional; progress item name. -* `todo` {Number} Optional; total amount of work to be done. Default 0. -* `weight` {Number} Optional; the weight of this item relative to others. Default 1. - -This adds a new `are-we-there-yet` item tracker to the progress tracker. The -object returned has the `log[level]` methods but is otherwise an -`are-we-there-yet` `Tracker` object. - -## log.newStream(name, todo, weight) - -This adds a new `are-we-there-yet` stream tracker to the progress tracker. The -object returned has the `log[level]` methods but is otherwise an -`are-we-there-yet` `TrackerStream` object. - -## log.newGroup(name, weight) - -This adds a new `are-we-there-yet` tracker group to the progress tracker. The -object returned has the `log[level]` methods but is otherwise an -`are-we-there-yet` `TrackerGroup` object. - -# Events - -Events are all emitted with the message object. - -* `log` Emitted for all messages -* `log.` Emitted for all messages with the `` level. -* `` Messages with prefixes also emit their prefix as an event. - -# Style Objects - -Style objects can have the following fields: - -* `fg` {String} Color for the foreground text -* `bg` {String} Color for the background -* `bold`, `inverse`, `underline` {Boolean} Set the associated property -* `bell` {Boolean} Make a noise (This is pretty annoying, probably.) - -# Message Objects - -Every log event is emitted with a message object, and the `log.record` -list contains all of them that have been created. They have the -following fields: - -* `id` {Number} -* `level` {String} -* `prefix` {String} -* `message` {String} Result of `util.format()` -* `messageRaw` {Array} Arguments to `util.format()` - -# Blocking TTYs - -We use [`set-blocking`](https://npmjs.com/package/set-blocking) to set -stderr and stdout blocking if they are tty's and have the setBlocking call. -This is a work around for an issue in early versions of Node.js 6.x, which -made stderr and stdout non-blocking on OSX.

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform. A single 4MB write could -// cause the system to run out of memory. -// -// However, even in such a pathological case, only a single written chunk -// would be consumed, and then the rest would wait (un-transformed) until -// the results of the previous transformed chunk were consumed. - -'use strict'; - -module.exports = Transform; - -var Duplex = require('./_stream_duplex'); - -/**/ -var util = Object.create(require('core-util-is')); -util.inherits = require('inherits'); -/**/ - -util.inherits(Transform, Duplex); - -function afterTransform(er, data) { - var ts = this._transformState; - ts.transforming = false; - - var cb = ts.writecb; - - if (!cb) { - return this.emit('error', new Error('write callback called multiple times')); - } - - ts.writechunk = null; - ts.writecb = null; - - if (data != null) // single equals check for both `null` and `undefined` - this.push(data); - - cb(er); - - var rs = this._readableState; - rs.reading = false; - if (rs.needReadable || rs.length < rs.highWaterMark) { - this._read(rs.highWaterMark); - } -} - -function Transform(options) { - if (!(this instanceof Transform)) return new Transform(options); - - Duplex.call(this, options); - - this._transformState = { - afterTransform: afterTransform.bind(this), - needTransform: false, - transforming: false, - writecb: null, - writechunk: null, - writeencoding: null - }; - - // start out asking for a readable event once data is transformed. - this._readableState.needReadable = true; - - // we have implemented the _read method, and done the other things - // that Readable wants before the first _read call, so unset the - // sync guard flag. - this._readableState.sync = false; - - if (options) { - if (typeof options.transform === 'function') this._transform = options.transform; - - if (typeof options.flush === 'function') this._flush = options.flush; - } - - // When the writable side finishes, then flush out anything remaining. - this.on('prefinish', prefinish); -} - -function prefinish() { - var _this = this; - - if (typeof this._flush === 'function') { - this._flush(function (er, data) { - done(_this, er, data); - }); - } else { - done(this, null, null); - } -} - -Transform.prototype.push = function (chunk, encoding) { - this._transformState.needTransform = false; - return Duplex.prototype.push.call(this, chunk, encoding); -}; - -// This is the part where you do stuff! -// override this function in implementation classes. -// 'chunk' is an input chunk. -// -// Call `push(newChunk)` to pass along transformed output -// to the readable side.

The default maxBusyTries is 3. - - Only relevant for async usage. - -* emfileWait - - If an `EMFILE` error is encountered, then rimraf will retry - repeatedly with a linear backoff of 1ms longer on each try, until - the timeout counter hits this max.

When you create a `Buffer` like -this, you **MUST** overwrite the contents before returning it to the user. - -From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size): - -> `new Buffer(size)` -> -> - `size` Number -> -> The underlying memory for `Buffer` instances created in this way is not initialized. -> **The contents of a newly created `Buffer` are unknown and could contain sensitive -> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes. - -(Emphasis our own.) - -Whenever the programmer intended to create an uninitialized `Buffer` you often see code -like this: - -```js -var buf = new Buffer(16) - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### Would this ever be a problem in real code? - -Yes. It's surprisingly common to forget to check the type of your variables in a -dynamically-typed language like JavaScript. - -Usually the consequences of assuming the wrong type is that your program crashes with an -uncaught exception. But the failure mode for forgetting to check the type of arguments to -the `Buffer` constructor is more catastrophic. - -Here's an example of a vulnerable service that takes a JSON payload and converts it to -hex: - -```js -// Take a JSON payload {str: "some string"} and convert it to hex -var server = http.createServer(function (req, res) { - var data = '' - req.setEncoding('utf8') - req.on('data', function (chunk) { - data += chunk - }) - req.on('end', function () { - var body = JSON.parse(data) - res.end(new Buffer(body.str).toString('hex')) - }) -}) - -server.listen(8080) -``` - -In this example, an http client just has to send: - -```json -{ - "str": 1000 -} -``` - -and it will get back 1,000 bytes of uninitialized memory from the server. - -This is a very serious bug. It's similar in severity to the -[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process -memory by remote attackers. - - -### Which real-world packages were vulnerable? - -#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht) - -[Mathias Buus](https://github.com/mafintosh) and I -([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages, -[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow -anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get -them to reveal 20 bytes at a time of uninitialized memory from the node.js process. - -Here's -[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8) -that fixed it. We released a new fixed version, created a -[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all -vulnerable versions on npm so users will get a warning to upgrade to a newer version. - -#### [`ws`](https://www.npmjs.com/package/ws) - -That got us wondering if there were other vulnerable packages. Sure enough, within a short -period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the -most popular WebSocket implementation in node.js. - -If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as -expected, then uninitialized server memory would be disclosed to the remote peer. - -These were the vulnerable methods: - -```js -socket.send(number) -socket.ping(number) -socket.pong(number) -``` - -Here's a vulnerable socket server with some echo functionality: - -```js -server.on('connection', function (socket) { - socket.on('message', function (message) { - message = JSON.parse(message) - if (message.type === 'echo') { - socket.send(message.data) // send back the user's message - } - }) -}) -``` - -`socket.send(number)` called on the server, will disclose server memory. - -Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue -was fixed, with a more detailed explanation. Props to -[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the -[Node Security Project disclosure](https://nodesecurity.io/advisories/67). - - -### What's the solution? - -It's important that node.js offers a fast way to get memory otherwise performance-critical -applications would needlessly get a lot slower. - -But we need a better way to *signal our intent* as programmers. **When we want -uninitialized memory, we should request it explicitly.** - -Sensitive functionality should not be packed into a developer-friendly API that loosely -accepts many different types. This type of API encourages the lazy practice of passing -variables in without checking the type very carefully. - -#### A new API: `Buffer.allocUnsafe(number)` - -The functionality of creating buffers with uninitialized memory should be part of another -API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that -frequently gets user input of all sorts of different types passed into it. - -```js -var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory! - -// Immediately overwrite the uninitialized buffer with data from another buffer -for (var i = 0; i < buf.length; i++) { - buf[i] = otherBuf[i] -} -``` - - -### How do we fix node.js core? - -We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as -`semver-major`) which defends against one case: - -```js -var str = 16 -new Buffer(str, 'utf8') -``` - -In this situation, it's implied that the programmer intended the first argument to be a -string, since they passed an encoding as a second argument. Today, node.js will allocate -uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not -what the programmer intended. - -But this is only a partial solution, since if the programmer does `new Buffer(variable)` -(without an `encoding` parameter) there's no way to know what they intended. If `variable` -is sometimes a number, then uninitialized memory will sometimes be returned. - -### What's the real long-term fix? - -We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when -we need uninitialized memory. But that would break 1000s of packages. - -~~We believe the best solution is to:~~ - -~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~ - -~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~ - -#### Update - -We now support adding three new APIs: - -- `Buffer.from(value)` - convert from any type to a buffer -- `Buffer.alloc(size)` - create a zero-filled buffer -- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size - -This solves the core problem that affected `ws` and `bittorrent-dht` which is -`Buffer(variable)` getting tricked into taking a number argument. - -This way, existing code continues working and the impact on the npm ecosystem will be -minimal. Over time, npm maintainers can migrate performance-critical code to use -`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`. - - -### Conclusion - -We think there's a serious design issue with the `Buffer` API as it exists today. It -promotes insecure software by putting high-risk functionality into a convenient API -with friendly "developer ergonomics". - -This wasn't merely a theoretical exercise because we found the issue in some of the -most popular npm packages. - -Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of -`buffer`. - -```js -var Buffer = require('safe-buffer').Buffer -``` - -Eventually, we hope that node.js core can switch to this new, safer behavior. We believe -the impact on the ecosystem would be minimal since it's not a breaking change. -Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while -older, insecure packages would magically become safe from this attack vector. - - -## links - -- [Node.js PR: buffer: throw if both length and enc are passed](https://github.com/nodejs/node/pull/4514) -- [Node Security Project disclosure for `ws`](https://nodesecurity.io/advisories/67) -- [Node Security Project disclosure for`bittorrent-dht`](https://nodesecurity.io/advisories/68) - - -## credit - -The original issues in `bittorrent-dht` -([disclosure](https://nodesecurity.io/advisories/68)) and -`ws` ([disclosure](https://nodesecurity.io/advisories/67)) were discovered by -[Mathias Buus](https://github.com/mafintosh) and -[Feross Aboukhadijeh](http://feross.org/). - -Thanks to [Adam Baldwin](https://github.com/evilpacket) for helping disclose these issues -and for his work running the [Node Security Project](https://nodesecurity.io/). - -Thanks to [John Hiesey](https://github.com/jhiesey) for proofreading this README and -auditing the code. - - -## license - -MIT.

Before Node.js 8, this buffer contained - *arbitrary memory* for performance reasons, which could include anything ranging from - program source code to passwords and encryption keys. -- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of - the string `'abc'`. A second argument could specify another encoding: For example, - `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original - sequence of bytes that it represents. -- There are several other combinations of arguments. - -This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell -what exactly the contents of the generated buffer are* without knowing the type of `foo`. - -Sometimes, the value of `foo` comes from an external source. For example, this function -could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: - -``` -function stringToBase64(req, res) { - // The request body should have the format of `{ string: 'foobar' }` - const rawBytes = new Buffer(req.body.string) - const encoded = rawBytes.toString('base64') - res.end({ encoded: encoded }) -} -``` - -Note that this code does *not* validate the type of `req.body.string`: - -- `req.body.string` is expected to be a string. If this is the case, all goes well. -- `req.body.string` is controlled by the client that sends the request. -- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: - - Before Node.js 8, the content would be uninitialized - - After Node.js 8, the content would be `50` bytes with the value `0` - -Because of the missing type check, an attacker could intentionally send a number -as part of the request. Using this, they can either: - -- Read uninitialized memory. This **will** leak passwords, encryption keys and other - kinds of sensitive information. (Information leak) -- Force the program to allocate a large amount of memory. For example, when specifying - `500000000` as the input value, each request will allocate 500MB of memory. - This can be used to either exhaust the memory available of a program completely - and make it crash, or slow it down significantly. (Denial of Service) - -Both of these scenarios are considered serious security issues in a real-world -web server context. - -when using `Buffer.from(req.body.string)` instead, passing a number will always -throw an exception instead, giving a controlled behaviour that can always be -handled by the program. - - -### The `Buffer()` constructor has been deprecated for a while. Is this really an issue? - -Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still -widely used.

It's just - XML. -* A DOM Builder - You can use it to build an object model out of XML, - but it doesn't do that out of the box. -* XSLT - No DOM = no querying. -* 100% Compliant with (some other SAX implementation) - Most SAX - implementations are in Java and do a lot more than this does. -* An XML Validator - It does a little validation when in strict mode, but - not much. -* A Schema-Aware XSD Thing - Schemas are an exercise in fetishistic - masochism. -* A DTD-aware Thing - Fetching DTDs is a much bigger job. - -## Regarding `Hello, world!').close(); - -// stream usage -// takes the same options as the parser -var saxStream = require("sax").createStream(strict, options) -saxStream.on("error", function (e) { - // unhandled errors will throw, since this is a proper node - // event emitter. - console.error("error!", e) - // clear the error - this._parser.error = null - this._parser.resume() -}) -saxStream.on("opentag", function (node) { - // same object as above -}) -// pipe is supported, and it's readable/writable -// same chunks coming in also go out. -fs.createReadStream("file.xml") - .pipe(saxStream) - .pipe(fs.createWriteStream("file-copy.xml")) -``` - - -## Arguments - -Pass the following arguments to the parser function. All are optional. - -`strict` - Boolean. Whether or not to be a jerk. Default: `false`. - -`opt` - Object bag of settings regarding string formatting. All default to `false`. - -Settings supported: - -* `trim` - Boolean. Whether or not to trim text and comment nodes. -* `normalize` - Boolean. If true, then turn any whitespace into a single - space. -* `lowercase` - Boolean. If true, then lowercase tag names and attribute names - in loose mode, rather than uppercasing them. -* `xmlns` - Boolean. If true, then namespaces are supported. -* `position` - Boolean. If false, then don't track line/col/position. -* `strictEntities` - Boolean. If true, only parse [predefined XML - entities](http://www.w3.org/TR/REC-xml/#sec-predefined-ent) - (`&`, `'`, `>`, `<`, and `"`) - -## Methods - -`write` - Write bytes onto the stream. You don't have to do this all at -once. You can keep writing as much as you want. - -`close` - Close the stream. Once closed, no more data may be written until -it is done processing the buffer, which is signaled by the `end` event. - -`resume` - To gracefully handle errors, assign a listener to the `error` -event. Then, when the error is taken care of, you can call `resume` to -continue parsing. Otherwise, the parser will not continue while in an error -state. - -## Members - -At all times, the parser object will have the following members: - -`line`, `column`, `position` - Indications of the position in the XML -document where the parser currently is looking. - -`startTagPosition` - Indicates the position where the current tag starts. - -`closed` - Boolean indicating whether or not the parser can be written to. -If it's `true`, then wait for the `ready` event to write again. - -`strict` - Boolean indicating whether or not the parser is a jerk. - -`opt` - Any options passed into the constructor. - -`tag` - The current tag being dealt with. - -And a bunch of other stuff that you probably shouldn't touch. - -## Events - -All events emit with a single argument. To listen to an event, assign a -function to `on`. Functions get executed in the this-context of -the parser object. The list of supported events are also in the exported -`EVENTS` array. - -When using the stream interface, assign handlers using the EventEmitter -`on` function in the normal fashion. - -`error` - Indication that something bad happened. The error will be hanging -out on `parser.error`, and must be deleted before parsing can continue. By -listening to this event, you can keep an eye on that kind of stuff. Note: -this happens *much* more in strict mode. Argument: instance of `Error`. - -`text` - Text node. Argument: string of text. - -`doctype` - The ``. Argument: -object with `name` and `body` members. Attributes are not parsed, as -processing instructions have implementation dependent semantics. - -`sgmldeclaration` - Random SGML declarations. Stuff like `` -would trigger this kind of event. This is a weird thing to support, so it -might go away at some point. SAX isn't intended to be used to parse SGML, -after all. - -`opentagstart` - Emitted immediately when the tag name is available, -but before any attributes are encountered. Argument: object with a -`name` field and an empty `attributes` set. Note that this is the -same object that will later be emitted in the `opentag` event. - -`opentag` - An opening tag. Argument: object with `name` and `attributes`. -In non-strict mode, tag names are uppercased, unless the `lowercase` -option is set. If the `xmlns` option is set, then it will contain -namespace binding information on the `ns` member, and will have a -`local`, `prefix`, and `uri` member. - -`closetag` - A closing tag. In loose mode, tags are auto-closed if their -parent closes. In strict mode, well-formedness is enforced. Note that -self-closing tags will have `closeTag` emitted immediately after `openTag`. -Argument: tag name. - -`attribute` - An attribute node. Argument: object with `name` and `value`. -In non-strict mode, attribute names are uppercased, unless the `lowercase` -option is set. If the `xmlns` option is set, it will also contains namespace -information. - -`comment` - A comment node. Argument: the string of the comment. - -`opencdata` - The opening tag of a ``) of a `` tags trigger a `"script"` -event, and their contents are not checked for special xml characters. -If you pass `noscript: true`, then this behavior is suppressed. - -## Reporting Problems - -It's best to write a failing test if you find an issue. I will always -accept pull requests with failing tests if they demonstrate intended -behavior, but it is very hard to figure out what issue you're describing -without a test.

Otherwise, download the [latest release](https://github.com/topojson/topojson-client/releases/latest). You can also load directly from [UNPKG](https://unpkg.com) as a [standalone library](https://unpkg.com/topojson-client@3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `topojson` global is exported: - -```html - - -``` - -The TopoJSON client API is implemented using ES2015 modules. In compatible environments, you can import the library as a namespace, like so: - -```js -import * as topojson from "topojson-client"; -``` - -[Try topojson-client in your browser.](https://runkit.com/npm/topojson-client) - -# API Reference - -# topojson.feature(topology, object) [<>](https://github.com/topojson/topojson-client/blob/master/src/feature.js "Source") - -Returns the GeoJSON Feature or FeatureCollection for the specified *object* in the given *topology*. If the specified object is a string, it is treated as *topology*.objects[*object*]. Then, if the object is a GeometryCollection, a FeatureCollection is returned, and each geometry in the collection is mapped to a Feature. Otherwise, a Feature is returned. The returned feature is a shallow copy of the source *object*: they may share identifiers, bounding boxes, properties and coordinates. - -Some examples: - -* A point is mapped to a feature with a geometry object of type “Point”. -* Likewise for line strings, polygons, and other simple geometries. -* A null geometry object (of type null in TopoJSON) is mapped to a feature with a null geometry object. -* A geometry collection of points is mapped to a feature collection of features, each with a point geometry. -* A geometry collection of geometry collections is mapped to a feature collection of features, each with a geometry collection. - -See [feature-test.js](https://github.com/topojson/topojson-client/blob/master/test/feature-test.js) for more examples. - -# topojson.merge(topology, objects) [<>](https://github.com/topojson/topojson-client/blob/master/src/merge.js#L5 "Source") - -Returns the GeoJSON MultiPolygon geometry object representing the union for the specified array of Polygon and MultiPolygon *objects* in the given *topology*. Interior borders shared by adjacent polygons are removed. See [Merging States](https://bl.ocks.org/mbostock/5416405) for an example. The returned geometry is a shallow copy of the source *object*: they may share coordinates. - -# topojson.mergeArcs(topology, objects) [<>](https://github.com/topojson/topojson-client/blob/master/src/merge.js#L9 "Source") - -Equivalent to [topojson.merge](#merge), but returns TopoJSON rather than GeoJSON. The returned geometry is a shallow copy of the source *object*: they may share coordinates. - -# topojson.mesh(topology[, object[, filter]]) [<>](https://github.com/topojson/topojson-client/blob/master/src/mesh.js#L4 "Source") - -Returns the GeoJSON MultiLineString geometry object representing the mesh for the specified *object* in the given *topology*. This is useful for rendering strokes in complicated objects efficiently, as edges that are shared by multiple features are only stroked once. If *object* is not specified, a mesh of the entire topology is returned. The returned geometry is a shallow copy of the source *object*: they may share coordinates. - -An optional *filter* function may be specified to prune arcs from the returned mesh using the topology. The filter function is called once for each candidate arc and takes two arguments, *a* and *b*, two geometry objects that share that arc. Each arc is only included in the resulting mesh if the filter function returns true. For typical map topologies the geometries *a* and *b* are adjacent polygons and the candidate arc is their boundary. If an arc is only used by a single geometry then *a* and *b* are identical. This property is useful for separating interior and exterior boundaries; an easy way to produce a mesh of interior boundaries is: - -```js -var interiors = topojson.mesh(topology, object, function(a, b) { return a !== b; }); -``` - -See this [county choropleth](https://bl.ocks.org/mbostock/4060606) for example. Note: the *a* and *b* objects are TopoJSON objects (pulled directly from the topology), and not automatically converted to GeoJSON features as by [topojson.feature](#feature). - -# topojson.meshArcs(topology[, object[, filter]]) [<>](https://github.com/topojson/topojson-client/blob/master/src/mesh.js#L8 "Source") - -Equivalent to [topojson.mesh](#mesh), but returns TopoJSON rather than GeoJSON. The returned geometry is a shallow copy of the source *object*: they may share coordinates. - -# topojson.neighbors(objects) [<>](https://github.com/topojson/topojson-client/blob/master/src/neighbors.js "Source") - -Returns an array representing the set of neighboring objects for each object in the specified *objects* array. The returned array has the same number of elements as the input array; each element *i* in the returned array is the array of indexes for neighbors of object *i* in the input array. For example, if the specified objects array contains the features *foo* and *bar*, and these features are neighbors, the returned array will be \[\[1\], \[0\]\], indicating that *foo* is a neighbor of *bar* and *vice versa*. Each array of neighbor indexes for each object is guaranteed to be sorted in ascending order. - -For a practical example, see the [world map](https://bl.ocks.org/mbostock/4180634) with topological coloring. - -### Transforms - -# topojson.bbox(topology) [<>](https://github.com/topojson/topojson-client/blob/master/src/bbox.js "Source") - -Returns the computed [bounding box](https://github.com/topojson/topojson-specification#3-bounding-boxes) of the specified *topology* [*x*₀, *y*₀, *x*₁, *y*₁] where *x*₀ is the minimum *x*-value, *y*₀ is the minimum *y*-value, *x*₁ is the maximum *x*-value, and *y*₁ is the maximum *y*-value. If the *topology* has no points and no arcs, the returned bounding box is [∞, ∞, -∞, -∞]. (This method ignores the existing *topology*.bbox, if any.) - -# topojson.quantize(topology, transform) [<>](https://github.com/topojson/topojson-client/blob/master/src/quantize.js "Source") - -Returns a shallow copy of the specified *topology* with [quantized and delta-encoded](https://github.com/topojson/topojson-specification#213-arcs) arcs according to the specified [*transform* object](https://github.com/topojson/topojson-specification/blob/master/README.md#212-transforms). If the *topology* is already quantized, an error is thrown. See also [topoquantize](#topoquantize). - -If a quantization number *n* is specified instead of a *transform* object, the corresponding transform object is first computed using the bounding box of the topology.

If this option is not specified, the [functions](#functions) method is used by default. - -- *blacklist*: An array of variable names that may **not** be referenced within the expression scope. These may correspond to disallowed global variables. - -- *whitelist*: An array of variable names that may be referenced within the expression scope. These typically correspond to function parameter names for the expression. Variable names not included in the white list will be collected as global variables (see *globalvar* below). - -- *fieldvar*: The name of the primary data input argument within the generated expression function. For example, in the function `function(d) { return d.x * d.y; }`, the variable `d` serves as the field variable, and `x` and `y` are it's accessed properties. All properties accessed under the scope of _fieldvar_ will be tracked by the code generator and returned as part of the output. This is necessary to perform dependency tracking of referenced data fields. - -- *globalvar*: (Required) The name of the variable upon which to lookup global variables. This variable name will be included in the generated code as the scope for any global variable references. Alternatively, this property can be a function that maps from variable names in the source input to generated code to write to the output. - -# -constants(codegen) -[<>](https://github.com/vega/vega/blob/master/packages/vega-expression/src/constants.js "Source") - -An object defining default constant values for the Vega expression language. The object maps from constant identifiers to JavaScript code to defining the constant value (for example, `'PI'` maps to `'Math.PI`'). - -# -functions(codegen) -[<>](https://github.com/vega/vega/blob/master/packages/vega-expression/src/functions.js "Source") - -Given a *codegen* instance (generated by the [codegen](#codegen) method) as input, returns an object defining all valid function names for use within an expression. The resulting object maps from function names to function values. The values may either be strings (which will be injected as-is into generated code and subsequently appended with arguments) or functions (which take an array of argument AST nodes as input and return generated code to inject). - -# -ASTNode(type) -[<>](https://github.com/vega/vega/blob/master/packages/vega-expression/src/ast.js "Source") - -Constructor for a node in an expression abstract syntax tree (AST). Accepts a *type* string as input, which then become the `type` property of the resulting node. AST nodes also support a `visit` method which takes a visitor function as input in order to traverse the AST for static analysis. - -## Provided Constants and Functions - -This package provides the following constants and functions: -

However, type is required for a field if:\n(1) the field is not nominal and the field encoding has no specified `aggregate` (except `argmin` and `argmax`), `bin`, scale type, custom `sort` order, nor `timeUnit`\nor (2) if you wish to use an ordinal scale for a field with `bin` or `timeUnit`.\n\n__Default value:__\n\n1) For a data `field`, `\"nominal\"` is the default data type unless the field encoding has `aggregate`, `channel`, `bin`, scale type, `sort`, or `timeUnit` that satisfies the following criteria:\n- `\"quantitative\"` is the default type if (1) the encoded field contains `bin` or `aggregate` except `\"argmin\"` and `\"argmax\"`, (2) the encoding channel is `latitude` or `longitude` channel or (3) if the specified scale type is [a quantitative scale](https://vega.github.io/vega-lite/docs/scale.html#type).\n- `\"temporal\"` is the default type if (1) the encoded field contains `timeUnit` or (2) the specified scale type is a time or utc scale\n- `ordinal\"\"` is the default type if (1) the encoded field contains a [custom `sort` order](https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order) or (2) the specified scale type is an ordinal/point/band scale.\n\n2) For a constant value in data domain (`datum`):\n- `\"quantitative\"` if the datum is a number\n- `\"nominal\"` if the datum is a string\n- `\"temporal\"` if the datum is [a date time object](https://vega.github.io/vega-lite/docs/datetime.html)\n\n__Note:__\n- Data `type` describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "Day": { - "maximum": 7, - "minimum": 1, - "type": "number" - }, - "DensityTransform": { - "additionalProperties": false, - "properties": { - "as": { - "description": "The output fields for the sample value and corresponding density estimate.\n\n__Default value:__ `[\"value\", \"density\"]`", - "items": [ - { - "$ref": "#/definitions/FieldName" - }, - { - "$ref": "#/definitions/FieldName" - } - ], - "maxItems": 2, - "minItems": 2, - "type": "array" - }, - "bandwidth": { - "description": "The bandwidth (standard deviation) of the Gaussian kernel.

For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "FacetMapping": { - "additionalProperties": false, - "properties": { - "column": { - "$ref": "#/definitions/FacetFieldDef", - "description": "A field definition for the horizontal facet of trellis plots." - }, - "row": { - "$ref": "#/definitions/FacetFieldDef", - "description": "A field definition for the vertical facet of trellis plots." - } - }, - "type": "object" - }, - "FacetMapping": { - "additionalProperties": false, - "properties": { - "column": { - "$ref": "#/definitions/FacetFieldDef", - "description": "A field definition for the horizontal facet of trellis plots." - }, - "row": { - "$ref": "#/definitions/FacetFieldDef", - "description": "A field definition for the vertical facet of trellis plots." - } - }, - "type": "object" - }, - "FacetedEncoding": { - "additionalProperties": false, - "properties": { - "angle": { - "$ref": "#/definitions/NumericMarkPropDef", - "description": "Rotation angle of point and text marks." - }, - "color": { - "$ref": "#/definitions/ColorDef", - "description": "Color of the marks – either fill or stroke color based on the `filled` property of mark definition.\nBy default, `color` represents fill color for `\"area\"`, `\"bar\"`, `\"tick\"`,\n`\"text\"`, `\"trail\"`, `\"circle\"`, and `\"square\"` / stroke color for `\"line\"` and `\"point\"`.\n\n__Default value:__ If undefined, the default color depends on [mark config](https://vega.github.io/vega-lite/docs/config.html#mark-config)'s `color` property.\n\n_Note:_\n1) For fine-grained control over both fill and stroke colors of the marks, please use the `fill` and `stroke` channels.

However, type is required for a field if:\n(1) the field is not nominal and the field encoding has no specified `aggregate` (except `argmin` and `argmax`), `bin`, scale type, custom `sort` order, nor `timeUnit`\nor (2) if you wish to use an ordinal scale for a field with `bin` or `timeUnit`.\n\n__Default value:__\n\n1) For a data `field`, `\"nominal\"` is the default data type unless the field encoding has `aggregate`, `channel`, `bin`, scale type, `sort`, or `timeUnit` that satisfies the following criteria:\n- `\"quantitative\"` is the default type if (1) the encoded field contains `bin` or `aggregate` except `\"argmin\"` and `\"argmax\"`, (2) the encoding channel is `latitude` or `longitude` channel or (3) if the specified scale type is [a quantitative scale](https://vega.github.io/vega-lite/docs/scale.html#type).\n- `\"temporal\"` is the default type if (1) the encoded field contains `timeUnit` or (2) the specified scale type is a time or utc scale\n- `ordinal\"\"` is the default type if (1) the encoded field contains a [custom `sort` order](https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order) or (2) the specified scale type is an ordinal/point/band scale.\n\n2) For a constant value in data domain (`datum`):\n- `\"quantitative\"` if the datum is a number\n- `\"nominal\"` if the datum is a string\n- `\"temporal\"` if the datum is [a date time object](https://vega.github.io/vega-lite/docs/datetime.html)\n\n__Note:__\n- Data `type` describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation.", - "enum": [ - "quantitative" - ], - "type": "string" - } - }, - "type": "object" - }, - "LayerRepeatMapping": { - "additionalProperties": false, - "properties": { - "column": { - "description": "An array of fields to be repeated horizontally.", - "items": { - "type": "string" - }, - "type": "array" - }, - "layer": { - "description": "An array of fields to be repeated as layers.", - "items": { - "type": "string" - }, - "type": "array" - }, - "row": { - "description": "An array of fields to be repeated vertically.", - "items": { - "type": "string" - }, - "type": "array" - } - }, - "required": [ - "layer" - ], - "type": "object" - }, - "LayerRepeatSpec": { - "additionalProperties": false, - "properties": { - "align": { - "anyOf": [ - { - "$ref": "#/definitions/LayoutAlign" - }, - { - "$ref": "#/definitions/RowCol" - } - ], - "description": "The alignment to apply to grid rows and columns.\nThe supported string values are `\"all\"`, `\"each\"`, and `\"none\"`.\n\n- For `\"none\"`, a flow layout will be used, in which adjacent subviews are simply placed one after the other.\n- For `\"each\"`, subviews will be aligned into a clean grid structure, but each row or column may be of variable size.\n- For `\"all\"`, subviews will be aligned and each row or column will be sized identically based on the maximum observed size.

However, type is required for a field if:\n(1) the field is not nominal and the field encoding has no specified `aggregate` (except `argmin` and `argmax`), `bin`, scale type, custom `sort` order, nor `timeUnit`\nor (2) if you wish to use an ordinal scale for a field with `bin` or `timeUnit`.\n\n__Default value:__\n\n1) For a data `field`, `\"nominal\"` is the default data type unless the field encoding has `aggregate`, `channel`, `bin`, scale type, `sort`, or `timeUnit` that satisfies the following criteria:\n- `\"quantitative\"` is the default type if (1) the encoded field contains `bin` or `aggregate` except `\"argmin\"` and `\"argmax\"`, (2) the encoding channel is `latitude` or `longitude` channel or (3) if the specified scale type is [a quantitative scale](https://vega.github.io/vega-lite/docs/scale.html#type).\n- `\"temporal\"` is the default type if (1) the encoded field contains `timeUnit` or (2) the specified scale type is a time or utc scale\n- `ordinal\"\"` is the default type if (1) the encoded field contains a [custom `sort` order](https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order) or (2) the specified scale type is an ordinal/point/band scale.\n\n2) For a constant value in data domain (`datum`):\n- `\"quantitative\"` if the datum is a number\n- `\"nominal\"` if the datum is a string\n- `\"temporal\"` if the datum is [a date time object](https://vega.github.io/vega-lite/docs/datetime.html)\n\n__Note:__\n- Data `type` describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "OrderValueDef": { - "additionalProperties": false, - "properties": { - "condition": { - "anyOf": [ - { - "$ref": "#/definitions/ConditionalValueDef" - }, - { - "items": { - "$ref": "#/definitions/ConditionalValueDef" - }, - "type": "array" - } - ], - "description": "One or more value definition(s) with [a selection or a test predicate](https://vega.github.io/vega-lite/docs/condition.html).\n\n__Note:__ A field definition's `condition` property can only contain [conditional value definitions](https://vega.github.io/vega-lite/docs/condition.html#value)\nsince Vega-Lite only allows at most one encoded field per encoding channel." - }, - "value": { - "description": "A constant value in visual domain (e.g., `\"red\"` / `\"#0099ff\"` / [gradient definition](https://vega.github.io/vega-lite/docs/types.html#gradient) for color, values between `0` to `1` for opacity).", - "type": "number" - } - }, - "required": [ - "value" - ], - "type": "object" - }, - "Orient": { - "enum": [ - "left", - "right", - "top", - "bottom" - ], - "type": "string" - }, - "Orientation": { - "enum": [ - "horizontal", - "vertical" - ], - "type": "string" - }, - "OverlayMarkDef": { - "additionalProperties": false, - "properties": { - "align": { - "$ref": "#/definitions/Align", - "description": "The horizontal alignment of the text or ranged marks (area, bar, image, rect, rule).

However, type is required for a field if:\n(1) the field is not nominal and the field encoding has no specified `aggregate` (except `argmin` and `argmax`), `bin`, scale type, custom `sort` order, nor `timeUnit`\nor (2) if you wish to use an ordinal scale for a field with `bin` or `timeUnit`.\n\n__Default value:__\n\n1) For a data `field`, `\"nominal\"` is the default data type unless the field encoding has `aggregate`, `channel`, `bin`, scale type, `sort`, or `timeUnit` that satisfies the following criteria:\n- `\"quantitative\"` is the default type if (1) the encoded field contains `bin` or `aggregate` except `\"argmin\"` and `\"argmax\"`, (2) the encoding channel is `latitude` or `longitude` channel or (3) if the specified scale type is [a quantitative scale](https://vega.github.io/vega-lite/docs/scale.html#type).\n- `\"temporal\"` is the default type if (1) the encoded field contains `timeUnit` or (2) the specified scale type is a time or utc scale\n- `ordinal\"\"` is the default type if (1) the encoded field contains a [custom `sort` order](https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order) or (2) the specified scale type is an ordinal/point/band scale.\n\n2) For a constant value in data domain (`datum`):\n- `\"quantitative\"` if the datum is a number\n- `\"nominal\"` if the datum is a string\n- `\"temporal\"` if the datum is [a date time object](https://vega.github.io/vega-lite/docs/datetime.html)\n\n__Note:__\n- Data `type` describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "SampleTransform": { - "additionalProperties": false, - "properties": { - "sample": { - "description": "The maximum number of data objects to include in the sample.\n\n__Default value:__ `1000`", - "type": "number" - } - }, - "required": [ - "sample" - ], - "type": "object" - }, - "Scale": { - "additionalProperties": false, - "properties": { - "align": { - "description": "The alignment of the steps within the scale range.\n\nThis value must lie in the range `[0,1]`.

For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - }, - "value": { - "anyOf": [ - { - "type": "number" - }, - { - "enum": [ - "width" - ], - "type": "string" - }, - { - "enum": [ - "height" - ], - "type": "string" - } - ], - "description": "A constant value in visual domain (e.g., `\"red\"` / `\"#0099ff\"` / [gradient definition](https://vega.github.io/vega-lite/docs/types.html#gradient) for color, values between `0` to `1` for opacity)." - } - }, - "type": "object" - }, - "yError": { - "additionalProperties": false, - "properties": { - "aggregate": { - "$ref": "#/definitions/Aggregate", - "description": "Aggregation function for the field\n(e.g., `\"mean\"`, `\"sum\"`, `\"median\"`, `\"min\"`, `\"max\"`, `\"count\"`).\n\n__Default value:__ `undefined` (None)\n\n__See also:__ [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html) documentation." - }, - "band": { - "description": "For rect-based marks (`rect`, `bar`, and `image`), mark size relative to bandwidth of [band scales](https://vega.github.io/vega-lite/docs/scale.html#band), bins or time units.

However, type is required for a field if:\n(1) the field is not nominal and the field encoding has no specified `aggregate` (except `argmin` and `argmax`), `bin`, scale type, custom `sort` order, nor `timeUnit`\nor (2) if you wish to use an ordinal scale for a field with `bin` or `timeUnit`.\n\n__Default value:__\n\n1) For a data `field`, `\"nominal\"` is the default data type unless the field encoding has `aggregate`, `channel`, `bin`, scale type, `sort`, or `timeUnit` that satisfies the following criteria:\n- `\"quantitative\"` is the default type if (1) the encoded field contains `bin` or `aggregate` except `\"argmin\"` and `\"argmax\"`, (2) the encoding channel is `latitude` or `longitude` channel or (3) if the specified scale type is [a quantitative scale](https://vega.github.io/vega-lite/docs/scale.html#type).\n- `\"temporal\"` is the default type if (1) the encoded field contains `timeUnit` or (2) the specified scale type is a time or utc scale\n- `ordinal\"\"` is the default type if (1) the encoded field contains a [custom `sort` order](https://vega.github.io/vega-lite/docs/sort.html#specifying-custom-sort-order) or (2) the specified scale type is an ordinal/point/band scale.\n\n2) For a constant value in data domain (`datum`):\n- `\"quantitative\"` if the datum is a number\n- `\"nominal\"` if the datum is a string\n- `\"temporal\"` if the datum is [a date time object](https://vega.github.io/vega-lite/docs/datetime.html)\n\n__Note:__\n- Data `type` describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "StringFieldDefWithCondition": { - "$ref": "#/definitions/FieldOrDatumDefWithCondition" - }, - "StringValueDefWithCondition": { - "$ref": "#/definitions/ValueDefWithCondition" - }, - "StrokeCap": { - "enum": [ - "butt", - "round", - "square" - ], - "type": "string" - }, - "StrokeJoin": { - "enum": [ - "miter", - "round", - "bevel" - ], - "type": "string" - }, - "StyleConfigIndex": { - "additionalProperties": { - "anyOf": [ - { - "$ref": "#/definitions/AnyMarkConfig" - }, - { - "$ref": "#/definitions/Axis" - } - ] - }, - "properties": { - "arc": { - "$ref": "#/definitions/RectConfig", - "description": "Arc-specific Config" - }, - "area": { - "$ref": "#/definitions/AreaConfig", - "description": "Area-Specific Config" - }, - "bar": { - "$ref": "#/definitions/BarConfig", - "description": "Bar-Specific Config" - }, - "circle": { - "$ref": "#/definitions/MarkConfig", - "description": "Circle-Specific Config" - }, - "geoshape": { - "$ref": "#/definitions/MarkConfig", - "description": "Geoshape-Specific Config" - }, - "group-subtitle": { - "$ref": "#/definitions/MarkConfig", - "description": "Default style for chart subtitles" - }, - "group-title": { - "$ref": "#/definitions/MarkConfig", - "description": "Default style for chart titles" - }, - "guide-label": { - "$ref": "#/definitions/MarkConfig", - "description": "Default style for axis, legend, and header labels." - }, - "guide-title": { - "$ref": "#/definitions/MarkConfig", - "description": "Default style for axis, legend, and header titles." - }, - "image": { - "$ref": "#/definitions/RectConfig", - "description": "Image-specific Config" - }, - "line": { - "$ref": "#/definitions/LineConfig", - "description": "Line-Specific Config" - }, - "mark": { - "$ref": "#/definitions/MarkConfig", - "description": "Mark Config" - }, - "point": { - "$ref": "#/definitions/MarkConfig", - "description": "Point-Specific Config" - }, - "rect": { - "$ref": "#/definitions/RectConfig", - "description": "Rect-Specific Config" - }, - "rule": { - "$ref": "#/definitions/MarkConfig", - "description": "Rule-Specific Config" - }, - "square": { - "$ref": "#/definitions/MarkConfig", - "description": "Square-Specific Config" - }, - "text": { - "$ref": "#/definitions/MarkConfig", - "description": "Text-Specific Config" - }, - "tick": { - "$ref": "#/definitions/TickConfig", - "description": "Tick-Specific Config" - }, - "trail": { - "$ref": "#/definitions/LineConfig", - "description": "Trail-Specific Config" - } - }, - "type": "object" - }, - "SymbolShape": { - "type": "string" - }, - "Text": { - "anyOf": [ - { - "type": "string" - }, - { - "items": { - "type": "string" - }, - "type": "array" - } - ] - }, - "TextBaseline": { - "anyOf": [ - { - "enum": [ - "alphabetic" - ], - "type": "string" - }, - { - "$ref": "#/definitions/Baseline" - }, - { - "enum": [ - "line-top" - ], - "type": "string" - }, - { - "enum": [ - "line-bottom" - ], - "type": "string" - } - ] - }, - "TextDef": { - "anyOf": [ - { - "$ref": "#/definitions/FieldOrDatumDefWithCondition" - }, - { - "$ref": "#/definitions/FieldOrDatumDefWithCondition" - }, - { - "$ref": "#/definitions/ValueDefWithCondition" - } - ] - }, - "TextDirection": { - "enum": [ - "ltr", - "rtl" - ], - "type": "string" - }, - "TickConfig": { - "additionalProperties": false, - "properties": { - "align": { - "$ref": "#/definitions/Align", - "description": "The horizontal alignment of the text or ranged marks (area, bar, image, rect, rule).

The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.\n- Data values for a temporal field can be either a date-time string (e.g., `\"2015-03-07 12:32:17\"`, `\"17:01\"`, `\"2015-03-16\"`. `\"2015\"`) or a timestamp number (e.g., `1552199579097`).\n- When using with [`bin`](https://vega.github.io/vega-lite/docs/bin.html), the `type` property can be either `\"quantitative\"` (for using a linear bin scale) or [`\"ordinal\"` (for using an ordinal bin scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`timeUnit`](https://vega.github.io/vega-lite/docs/timeunit.html), the `type` property can be either `\"temporal\"` (default, for using a temporal scale) or [`\"ordinal\"` (for using an ordinal scale)](https://vega.github.io/vega-lite/docs/type.html#cast-bin).\n- When using with [`aggregate`](https://vega.github.io/vega-lite/docs/aggregate.html), the `type` property refers to the post-aggregation data type. For example, we can calculate count `distinct` of a categorical field `\"cat\"` using `{\"aggregate\": \"distinct\", \"field\": \"cat\"}`. The `\"type\"` of the aggregate output is `\"quantitative\"`.\n- Secondary channels (e.g., `x2`, `y2`, `xError`, `yError`) do not have `type` as they must have exactly the same type as their primary channels (e.g., `x`, `y`).\n\n__See also:__ [`type`](https://vega.github.io/vega-lite/docs/type.html) documentation." - } - }, - "type": "object" - }, - "UnitSpec": { - "additionalProperties": false, - "description": "A unit specification, which can contain either [primitive marks or composite marks](https://vega.github.io/vega-lite/docs/mark.html#types).", - "properties": { - "data": { - "anyOf": [ - { - "$ref": "#/definitions/Data" - }, - { - "type": "null" - } - ], - "description": "An object describing the data source.

This method does not perform any parsing, it simply returns the loaded data as either a Buffer or String instance, depending on the execution environment. To subsequently parse loaded data, use the [read](#read) method. - -The *uri* argument is a value indicating the file to load. This is typically either an absolute or relative URL string. If running server-side via node.js, this argument might also be a file path (e.g., `'file:///path/to/file.txt'`). - -If provided, the *options* argument will be combined with any default options passed to the [loader](#loader) constructor.

This method is used internally by [load](#load) to ensure the URL is valid and to add additional protocol and hostname information, if needed. This method accepts the same *options* object accepted by [load](#load) and returns a Promise. If sanitization is successful, the Promise resolves to a return object containing the URL string as (_href_), along with a non-enumerable boolean _localFile_ flag, indicating if the file should be loaded from the local filesystem. The Promise rejects if the *uri* is invalid or disallowed.

The *data* argument should be either a String or Buffer instance, typically the result of calling [load](#load). - -The *schema* object contents may depend on the data format (see below). Common options include: - -- *type*: The data format type, such as `json`, `csv`, `tsv`, or `topojson`. -- *property*: For JSON types, specifies a property of the loaded JSON to reference. This is useful if a loaded JSON file contains multiple data sets and one would like to parse data under a specific property. -- *parse*: When set to `'auto'`, the method will perform type inference (using the [inferTypes](#inferTypes) method) to determine data types of each field. Alternatively, callers can specify parsing rules by providing an object mapping field names to data types (for example: `{'timestamp': 'date', 'price': 'number'}`). The valid data type options are `'boolean'`, `'integer'`, `'number'`, `'date'`, and `'string'`. - -The `'date'` data type also accepts an optional format string (`'date:format'`). If provided, the optional *dateParse* function is used to generate date-time parsers for a date format string. If *dateParse* is unspecified, the [d3-time-format](https://github.com/d3/d3-time-format) library is used by default. Date-time format strings may be quoted (`date:'%A'`), but quoting is not required. In addition, parsing of date-time format strings to UTC time is supported (`'utc:format'`). - -```js -// read loaded csv data, automatically infer value types -var data = null; -loader.load('data/stocks.csv').then(function(data) { - data = vega.read(csv_data, {type: 'csv', parse: 'auto'}); -}); -``` - -```js -// read loaded csv data, using provided value types -var data = null; -loader.load('data/stocks.csv').then(function(data) { - data = vega.read(data, { - type: 'csv', - parse: {'date': 'date', 'price': 'number'} - }); -}); -``` - -```js -// read loaded topojson data, extract mesh of countries -var topojson = null; -loader.load('data/world-110m.json').then(function(data) { - topojson = vega.read(data, {type: 'topojson', mesh: 'countries'}); -}); -``` - -# -vega.inferType(values[, field]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-loader/src/type.js "Source") - -Given an array of *values*, infers their data type as one of `'boolean'`, `'integer'`, `'number'`, `'date'`, or `'string'`.

If provided, the *parser* function is used to interpret the *value*; otherwise `Date.parse` is used. -- typeParsers.string(value): Parse the input *value* to a String. If *value* is not already string-typed, it is coerced to a String. - -# -vega.formats(name[, format]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-loader/src/formats/index.js "Source") - -Registry function for data format parsers. If invoked with two arguments, adds a new *format* parser with the provided *name*. Otherwise, returns an existing parser with the given *name*. The method signature of a format parser is: - -- format(data, options) - -A format parser that accepts two arguments, the input *data* to parse (e.g., a block of CSV text) and a set of format-specific *options*. The following data formats are registered by default: - -- *dsv*: Delimiter-separated values format. Each line of text is a record, with each field separated by a delimiter string. Accepts a *delimiter* option indicating the delimiter string used to separate field values. -- *csv*: Comma-separated values format. A *dsv* instance with a comma (`,`) delimiter. -- *tsv*: Tab-separated values format. A *dsv* instance with a tab (`\t`) delimiter. -- *json*: [JavaScript Object Notation (JSON)](https://en.wikipedia.org/wiki/JSON) format. Accepts a *property* option, indicating a sub-property of the parsed JSON to return; useful if a data array is nested within a larger object. Also accepts a *copy* option (default `false`), which will defensively copy a JSON Object that was passed to Vega directly, rather than parsed from a string. -- *topojson*: [TopoJSON](https://github.com/mbostock/topojson/wiki) format for compressed encoding of geographic data. Requires either a *feature* option indicating the name of the geographic feature to extract (e.g., extracts individual paths for all countries), or a *mesh* option indicating a feature name for which a single mesh should be extracted (e.g., all country boundaries in a single path).

This package supports both pixel-based (canvas) and vector graphics (SVG) output. Renderers can either (re-)draw a complete scene or perform incremental re-rendering for a set of provided "dirty" items. A fast SVG string renderer is also provided to generate static SVG for export. - -The [node-canvas](https://github.com/Automattic/node-canvas) library is used for server-side canvas rendering and bounds calculation. Node-canvas requires the native Cairo graphics library and may attempt to compile native code as part of the installation process. In some instances this may result in installation hiccups. Should you run into issues, you are likely to resolve them more quickly if you first search for help regarding node-canvas (as opposed to vega-scenegraph) installation. However, node-canvas is not a strict dependency, and is not needed for SVG rendering. Bounds calculation can be performed without node-canvas, though in the case of text marks the resulting bounds may be inaccurate due to approximate text size calculations. - -## Scenegraph Definition - -The Vega scenegraph is a hierarchical (tree) data structure. The levels of the tree alternate between an enclosing *mark* definition and contained sets of mark instances called *items*. - -For example, here is a simple scenegraph containing three rectangles: - -```json -{ - "marktype": "rect", - "items": [ - {"x": 0, "y": 0, "width": 50, "height": 50, "fill": "steelblue"}, - {"x": 100, "y": 50, "width": 50, "height": 50, "fill": "firebrick"}, - {"x": 50, "y": 100, "width": 50, "height": 50, "fill": "forestgreen"} - ] -} -``` - -The supported mark types are rectangles (`rect`), plotting symbols (`symbol`), general paths or polygons (`path`), circular arcs (`arc`), filled areas (`area`), lines (`line`), images (`image`), text labels (`text`), and chart gridlines or rules (`rule`). Each item has a set of supported properties (`x`, `y`, `width`, `fill`, and so on) appropriate to the mark type. - -Scenegraphs may also contain `group` marks, which serve as containers for other marks. For example, a top-level group mark may look like: - -```json -{ - "marktype": "group", - "items": [ - { - "x": 0, - "y": 0, - "width": 200, - "height": 200, - "items": [...] // array of contained mark instances - } - ] -} -``` - -In this example, the group *mark* contains only a single group *item*. In practice, a group mark may contain any number of group items, for example to describe a scene with multiple layers or sub-plots. - -For more information regarding supported mark properties, please see the [Vega marks documentation](https://vega.github.io/vega/docs/marks/). - -## Scenegraph Serialization - -The top-level export of this package includes `fromJSON` and `toJSON` methods to support scenegraph serialization. The `fromJSON` method expects a JSON string as input (similar to the examples listed above). It will then add additional parent pointers to the tree structure. For example, each item will have a `mark` property pointing to its parent mark, and each mark will have a `group` property pointing to its parent group (if any). The `toJSON` method maps a scenegraph instance to a JSON string, stripping any parent pointers or other non-standard properties. - -## Test Suite - -The vega-scengraph test suite compares rendered output for both Canvas (PNG) and SVG (text) renderers. Due to differences among platforms, pixel-level rendering by node-canvas can differ across operating systems. As a result, some test cases may break when running on a system other than Mac OS X (our standard platform for testing). If you are running on Linux or Windows and experience test failures, it does not necessarily indicate an issue with vega-scenegraph. In such cases, we recommend running the node-canvas test-server (`npm run test-server` from the node-canvas repository) to compare server-side and client-side rendering. diff --git

A single _unit_ value is one of the following strings: - -- `'year'` - [Gregorian calendar](https://en.wikipedia.org/wiki/Gregorian_calendar) years. -- `'quarter'` - Three-month intervals, starting in one of January, April, July, and October. -- `'month'` - Calendar months (January, February, _etc._). -- `'date'` - Calendar day of the month (January 1, January 2, _etc._). -- `'week'` - Sunday-based weeks. Days before the first Sunday of the year are considered to be in week 0, the first Sunday of the year is the start of week 1, the second Sunday week 2, _etc._. -- `'day'` - Day of the week (Sunday, Monday, _etc._). -- `'dayofyear'` - Day of the year (1, 2, ..., 365, _etc._). -- `'hours'` - Hours of the day (12:00am, 1:00am, _etc_.). -- `'minutes'` - Minutes in an hour (12:00, 12:01, _etc_.). -- `'seconds'` - Seconds in a minute (12:00:00, 12:00:01, _etc_.). -- `'milliseconds'` - Milliseconds in a second. - -Multiple _units_ can be listed in an array to indicate desired intervals of time. For example, `['year', 'month', 'date']` indicates chronological time sensitive to year, month, and date (but not to hours, minutes, or seconds). The specifier `['month', 'date']` is sensitive to month and date, but not year, which can be useful for binning time values to look at seasonal patterns only. - -# -vega.timeUnits(units) -[<>](https://github.com/vega/vega/blob/master/packages/vega-time/src/units.js "Source") - -Returns a standardized and sorted specifier for the given _units_, which must be an array of one or more valid time unit strings. The returned array contains the same units, sorted in decreasing over of unit size, such that the most granular unit is last (for example, `['year', 'month', 'date']`). This method throws an error if the _units_ array is empty, contains an invalid unit, or contains incompatible units. Specifically, the `'quarter'`, `'month'`, and `'date'` units can not be used in conjunction with the `'week'` or `'day'` units. - -# -vega.timeUnitSpecifier(units[, specifiers]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-time/src/format.js "Source") - -Returns a time format specifier string for the given time _units_. The optional _specifiers_ object provides a set of desired specifier sub-strings for customizing the resulting time formats. The _specifiers_ object may contain keys for both single time units (`"year"`) and time unit sequences (`"year-month-date"`). This method will first standardize the input time units using the [timeUnits](#timeUnits) method. It will then search, starting from the beginning of the units array, for the largest matching sequence defined in the specifiers object. Matching entries are then concatenated together, and the resulting string is whitespace-trimmed and returned. - -If no _specifiers_ object is provided, the following defaults are used: - -```json -{ - "year": "%Y ", - "year-month": "%Y-%m ", - "year-month-date": "%Y-%m-%d ", - "quarter": "Q%q ", - "month": "%b ", - "date": "%d ", - "week": "W%U ", - "day": "%a ", - "hours": "%H:00", - "hours-minutes": "%H:%M", - "minutes": "00:%M", - "seconds": ":%S", - "milliseconds": ".%L" -} -``` - -If a _specifiers_ object is provided, its values are merged with the defaults above. As a result, for complete control callees may wish to override the multi-unit `"year-month"`, `"year-month-date"`, and `"hours-minutes"` entries in addition to any individual unit entries. The input _specifiers_ object can use a `null` value to invalidate an entry in the defaults. - -# -vega.timeBin(options) -[<>](https://github.com/vega/vega/blob/master/packages/vega-time/src/bin.js "Source") - -Determine a temporal binning scheme, for example to create a histogram. Based on the options provided given, this method will search over a space of possible time unit bins, applying constraints such as the maximum number of allowable bins. Given a set of options (see below), returns an object describing the binning scheme, in terms of `units` and `step` properties. These values can then be used as input to the [timeFloor](#timeFloor) or [utcFloor](#utcFloor) methods. - -The supported options properties are: - -- _extent_: (required) A two-element (`[min, max]`) array indicating the date range over which the bin values are defined. -- _maxbins_: The maximum number of allowable bins (default `40`). - -### Local Time Utilities - -# -vega.timeFloor(units[, step]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-time/src/floor.js "Source") - -Returns a function that performs flooring (truncation) of input dates to given time _units_ in the local timezone.

The *fields* argument must be either a string, an accessor function, or an array of either. Strings indicate the name of object properties to sort by, in precedence order. Field strings may include nested properties (e.g., `foo.bar.baz`). The *orders* argument must be either a string or an array of strings; the valid string values are `'ascending'` (for ascending sort order of the corresponding field) or `'descending'` (for descending sort order of the corresponding field). If the *orders* argument is omitted, is shorter than the *fields* array, or includes values other than `'ascending'` or `'descending'`, corresponding fields will default to ascending order. - -# -vega.constant(value) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/constant.js "Source") - -Given an input *value*, returns a function that simply returns that value.

Assigns the `prototype` property of the input *child* function, such that the *child* inherits the properties of the *parent* function's prototype via prototypal inheritance. Returns the new child prototype object. - -# -vega.lruCache([maxsize]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/lruCache.js "Source") - -Provides a key/value cache, keyed by string, that evicts least recently used (LRU) entries. Supports *has*, *get*, *set*, and *clear* methods. The optional *maxsize* argument (default 10,000) determines the maximum number of elements that can be added before items are evicted. - -In the internal implementation two caches are used: a current cache and a previous cache. When then current cache fills, it becomes the previous cache and a new, empty current cache is created. Subsequent *get* calls will promote elements in the previous cache to the current cache. Once the current cache fills, the caches are again turned over and all LRU items still residing in the previous cache are dropped. - -```js -var cache = vega.lruCache(1); // use 1-element cache to demonstrate -cache.set('a', 1); // current cache has a->1 -cache.set('b', 2); // current cache has b->2, previous cache has a->1 -cache.get('a'); // -> 1 (a now in current cache, b in previous cache) -cache.set('c', 3); // current cache has c->3, previous cache has a->1 -cache.has('c'); // -> true (c is in the current cache) -cache.has('b'); // -> false (b has been evicted) -cache.has('a'); // -> true (a is in the previous cache) -cache.get('c'); // -> 3 -cache.clear(); -``` - -# -vega.fastmap([object]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/fastmap.js "Source") - -Provides a key/value map data structure, keyed by string. Supports a subset of the [ES6 Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) API, including *has*, *get*, *set*, *delete* and *clear* methods and a *size* property. If the optional *object* argument is provided, all key/values on the input object will be added to the new map instance. - -```js -var map = vega.fastmap({foo:1, bar:2}); -map.has('foo'); // -> true -map.get('foo'); // -> 1 -map.delete('bar'); -map.has('bar'); // -> false -map.set('baz', 0); -map.get('baz'); // -> 0 -map.size; // -> 2 -map.empty; // -> 1 (number of empty entries) -map.clean(); // invoke garbage collection, clears empty entries -``` - -By using basic JavaScript objects to hash values and avoiding calls to the built-in JavaScript `delete` operator, fastmaps provide good performance. However, this speed comes at the cost of some object bloat, requiring periodic garbage collection in the case of many deletions. The fastmap object provides a *clean* method for requesting garbage collection of empty map entries. The *test* method is a getter/setter for providing an optional boolean-valued function that indicates additional objects (not just empty entries from deleted keys) that should be removed during garbage collection. - -# -vega.hasOwnProperty(object, property) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/hasOwnProperty.js "Source") - -Returns `true` if the input *object* has a named *property* defined on it, otherwise `false`. This method concerns the input object only, ignoring properties defined up the prototype chain. The method is equivalent to [`Object.hasOwnProperty`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwnProperty), but improves security by guarding against overridden Object prototype built-ins. - -# -vega.mergeConfig(...config) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/mergeConfig.js "Source") - -Merges a collection of Vega configuration objects into a single combined object. Configuration objects with higher index positions in the arguments list have higher precedence, and so may override settings provided by earlier objects. - -# -vega.writeConfig(config, key, value[, recurse]) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/mergeConfig.js "Source") - -Writes a value to a Vega configuration object. Given a *config* object and a configuration property *key* and *value*, appropriately assign the value to the config object. The *recurse* parameter controls if recursive merging (as opposed to overwriting) is performed: if `false` or undefined, no recursion is performed; if `true` one level of recursive merge is performed; if *recurse* is object-valued, one level of recursive merge is performed for keys that the *recurse* object maps to a truthy value. This method is a helper method used within *mergeConfig*. - -### Arrays - -Functions for manipulating JavaScript Array values. - -# -vega.array(value) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/array.js "Source") - -Ensures that the input *value* is an Array instance. If so, the *value* is simply returned. If not, the *value* is wrapped within a new single-element an array, returning `[value]`. - -# -vega.clampRange(range, min, max) -[<>](https://github.com/vega/vega/blob/master/packages/vega-util/src/clampRange.js "Source") - -Span-preserving range clamp.

We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## Maintainers - -- [Sindre Sorhus](https://github.com/sindresorhus) -- [Josh Junon](https://github.com/qix-) - - ---- - -

We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them. - -On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out. - - -## Maintainers - -- [Sindre Sorhus](https://github.com/sindresorhus) -- [Josh Junon](https://github.com/qix-) - - ---- - -
