+Default: `false` *(Matches any ANSI escape codes in a string)* + +Match only the first ANSI escape. + + +## FAQ + +### Why do you test for codes not in the ECMA 48 standard? + +Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. 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-) + + +--- + +

+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+// may be degraded to fit that color palette. This means terminals
+// that do not support 16 million colors will best-match the
+// original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles

+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+# get-caller-file
+
+[](https://travis-ci.org/stefanpenner/get-caller-file)
+[](https://ci.appveyor.com/project/embercli/get-caller-file/branch/master)
+
+This is a utility, which allows a function to figure out from which file it was invoked. It does so by inspecting v8's stack trace at the time it is invoked.
+
+Inspired by http://stackoverflow.com/questions/13227489
+
+*note: this relies on Node/V8 specific APIs, as such other runtimes may not work*
+
+## Installation
+
+```bash
+yarn add get-caller-file
+```
+
+## Usage
+
+Given:
+
+```js
+// ./foo.js
+const getCallerFile = require('get-caller-file');
+
+module.exports = function() {
+ return getCallerFile(); // figures out who called it
+};
+```
+
+```js
+// index.js
+const foo = require('./foo');
+
+foo() // => /full/path/to/this/file/index.js
+```
+
+
+## Options:
+
+* `getCallerFile(position = 2)`: where position is stack frame whos fileName we want.

+Recognized extensions are `png`, `svg` and `txt`. + +### Browser +`node-qrcode` can be used in browser through module bundlers like [Browserify](https://github.com/substack/node-browserify) and [Webpack](https://github.com/webpack/webpack) or by including the precompiled bundle present in `build/` folder. + +#### Module bundlers +```html + + + + + + + +``` + +```javascript +// index.js -> bundle.js +var QRCode = require('qrcode') +var canvas = document.getElementById('canvas') + +QRCode.toCanvas(canvas, 'sample text', function (error) { + if (error) console.error(error) + console.log('success!'); +}) +``` + +#### Precompiled bundle +```html + + + + +``` + +If you install through `npm`, precompiled files will be available in `node_modules/qrcode/build/` folder. + +The precompiled bundle have support for [Internet Explorer 10+, Safari 5.1+, and all evergreen browsers](https://browserl.ist/?q=defaults%2C+IE+%3E%3D+10%2C+Safari+%3E%3D+5.1). + +### NodeJS +Require the module `qrcode` + +```javascript +var QRCode = require('qrcode') + +QRCode.toDataURL('I am a pony!', function (err, url) { + console.log(url) +}) +``` + +render a qrcode for the terminal +```js +var QRCode = require('qrcode') + +QRCode.toString('I am a pony!',{type:'terminal'}, function (err, url) { + console.log(url) +}) +``` + +### ES6/ES7 +Promises and Async/Await can be used in place of callback function. + +```javascript +import QRCode from 'qrcode' + +// With promises +QRCode.toDataURL('I am a pony!') + .then(url => { + console.log(url) + }) + .catch(err => { + console.error(err) + }) + +// With async/await +const generateQR = async text => { + try { + console.log(await QRCode.toDataURL(text)) + } catch (err) { + console.error(err) + } +} +``` + +## Error correction level +Error correction capability allows to successfully scan a QR Code even if the symbol is dirty or damaged. +Four levels are available to choose according to the operating environment. + +Higher levels offer a better error resistance but reduce the symbol's capacity.
+If the chances that the QR Code symbol may be corrupted are low (for example if it is showed through a monitor) +is possible to safely use a low error level such as `Low` or `Medium`. + +Possible levels are shown below: + +| Level | Error resistance | +|------------------|:----------------:| +| **L** (Low) | **~7%** | +| **M** (Medium) | **~15%** | +| **Q** (Quartile) | **~25%** | +| **H** (High) | **~30%** | + +The percentage indicates the maximum amount of damaged surface after which the symbol becomes unreadable. + +Error level can be set through `options.errorCorrectionLevel` property.
+If not specified, the default value is `M`. + +```javascript +QRCode.toDataURL('some text', { errorCorrectionLevel: 'H' }, function (err, url) { + console.log(url) +}) +``` + +## QR Code capacity +Capacity depends on symbol version and error correction level. Also encoding modes may influence the amount of storable data. + +The QR Code versions range from version **1** to version **40**.
+Each version has a different number of modules (black and white dots), which define the symbol's size. +For version 1 they are `21x21`, for version 2 `25x25` e so on. +Higher is the version, more are the storable data, and of course bigger will be the QR Code symbol. + +The table below shows the maximum number of storable characters in each encoding mode and for each error correction level. + +| Mode | L | M | Q | H | +|--------------|------|------|------|------| +| Numeric | 7089 | 5596 | 3993 | 3057 | +| Alphanumeric | 4296 | 3391 | 2420 | 1852 | +| Byte | 2953 | 2331 | 1663 | 1273 | +| Kanji | 1817 | 1435 | 1024 | 784 | + +**Note:** Maximum characters number can be different when using [Mixed modes](#mixed-modes). + +QR Code version can be set through `options.version` property.
+If no version is specified, the more suitable value will be used. Unless a specific version is required, this option is not needed. + +```javascript +QRCode.toDataURL('some text', { version: 2 }, function (err, url) { + console.log(url) +}) +``` + +## Encoding modes +Modes can be used to encode a string in a more efficient way.
+A mode may be more suitable than others depending on the string content. +A list of supported modes are shown in the table below: + +| Mode | Characters | Compression | +|--------------|-----------------------------------------------------------|-------------------------------------------| +| Numeric | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 | 3 characters are represented by 10 bits | +| Alphanumeric | 0–9, A–Z (upper-case only), space, $, %, *, +, -, ., /, : | 2 characters are represented by 11 bits | +| Kanji | Characters from the Shift JIS system based on JIS X 0208 | 2 kanji are represented by 13 bits | +| Byte | Characters from the ISO/IEC 8859-1 character set | Each characters are represented by 8 bits | + +Choose the right mode may be tricky if the input text is unknown.
+In these cases **Byte** mode is the best choice since all characters can be encoded with it. (See [Multibyte characters](#multibyte-characters))
+However, if the QR Code reader supports mixed modes, using [Auto mode](#auto-mode) may produce better results. + +### Mixed modes +Mixed modes are also possible. A QR code can be generated from a series of segments having different encoding modes to optimize the data compression.
+However, switching from a mode to another has a cost which may lead to a worst result if it's not taken into account. +See [Manual mode](#manual-mode) for an example of how to specify segments with different encoding modes. + +### Auto mode +By **default**, automatic mode selection is used.
+The input string is automatically splitted in various segments optimized to produce the shortest possible bitstream using mixed modes.
+This is the preferred way to generate the QR Code. + +For example, the string **ABCDE12345678?A1A** will be splitted in 3 segments with the following modes: + +| Segment | Mode | +|----------|--------------| +| ABCDE | Alphanumeric | +| 12345678 | Numeric | +| ?A1A | Byte | + +Any other combinations of segments and modes will result in a longer bitstream.
+If you need to keep the QR Code size small, this mode will produce the best results. + +### Manual mode +If auto mode doesn't work for you or you have specific needs, is also possible to manually specify each segment with the relative mode. +In this way no segment optimizations will be applied under the hood.
+Segments list can be passed as an array of object: + +```javascript + var QRCode = require('qrcode') + + var segs = [ + { data: 'ABCDEFG', mode: 'alphanumeric' }, + { data: '0123456', mode: 'numeric' } + ] + + QRCode.toDataURL(segs, function (err, url) { + console.log(url) + }) +``` + +### Kanji mode +With kanji mode is possible to encode characters from the Shift JIS system in an optimized way.
+Unfortunately, there isn't a way to calculate a Shifted JIS values from, for example, a character encoded in UTF-8, for this reason a conversion table from the input characters to the SJIS values is needed.
+This table is not included by default in the bundle to keep the size as small as possible. + +If your application requires kanji support, you will need to pass a function that will take care of converting the input characters to appropriate values. + +An helper method is provided by the lib through an optional file that you can include as shown in the example below. + +**Note:** Support for Kanji mode is only needed if you want to benefit of the data compression, otherwise is still possible to encode kanji using Byte mode (See [Multibyte characters](#multibyte-characters)). + +```javascript + var QRCode = require('qrcode') + var toSJIS = require('qrcode/helper/to-sjis') + + QRCode.toDataURL(kanjiString, { toSJISFunc: toSJIS }, function (err, url) { + console.log(url) + }) +``` + +With precompiled bundle: + +```html + + + + + +``` + +## Binary data +QR Codes can hold arbitrary byte-based binary data. If you attempt to create a binary QR Code by first converting the data to a JavaScript string, it will fail to encode propery because string encoding adds additional bytes. Instead, you must pass a [`Uint8ClampedArray`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8ClampedArray) or compatible array, or a Node [Buffer](https://nodejs.org/api/buffer.html), as follows: + +```javascript +// Regular array example +// WARNING: Element values will be clamped to 0-255 even if your data contains higher values. +const QRCode = require('qrcode') +QRCode.toFile( + 'foo.png', + [{ data: [253,254,255], mode: 'byte' }], + ...options..., + ...callback... +) +``` + +```javascript +// Uint8ClampedArray example +const QRCode = require('qrcode') + +QRCode.toFile( + 'foo.png', + [{ data: new Uint8ClampedArray([253,254,255]), mode: 'byte' }], + ...options..., + ...callback... +) +``` + +```javascript +// Node Buffer example +// WARNING: Element values will be clamped to 0-255 even if your data contains higher values. +const QRCode = require('qrcode') + +QRCode.toFile( + 'foo.png', + [{ data: Buffer.from([253,254,255]), mode: 'byte' }], + ...options..., + ...callback... +) +``` + +TypeScript users: if you are using [@types/qrcode](https://www.npmjs.com/package/@types/qrcode), you will need to add a `// @ts-ignore` above the data segment because it expects `data: string`. + +## Multibyte characters +Support for multibyte characters isn't present in the initial QR Code standard, but is possible to encode UTF-8 characters in Byte mode. + +QR Codes provide a way to specify a different type of character set through ECI (Extended Channel Interpretation), but it's not fully implemented in this lib yet. + +Most QR Code readers, however, are able to recognize multibyte characters even without ECI. + +Note that a single Kanji/Kana or Emoji can take up to 4 bytes. + +## API +Browser: +- [create()](#createtext-options) +- [toCanvas()](#tocanvascanvaselement-text-options-cberror) +- [toDataURL()](#todataurltext-options-cberror-url) +- [toString()](#tostringtext-options-cberror-string) + +Server: +- [create()](#createtext-options) +- [toCanvas()](#tocanvascanvas-text-options-cberror) +- [toDataURL()](#todataurltext-options-cberror-url-1) +- [toString()](#tostringtext-options-cberror-string-1) +- [toFile()](#tofilepath-text-options-cberror) +- [toFileStream()](#tofilestreamstream-text-options) + +### Browser API +#### `create(text, [options])` +Creates QR Code symbol and returns a qrcode object. + +##### `text` +Type: `String|Array` + +Text to encode or a list of objects describing segments. + +##### `options` +See [QR Code options](#qr-code-options). + +##### `returns` +Type: `Object` + +```javascript +// QRCode object +{ + modules, // Bitmatrix class with modules data + version, // Calculated QR Code version + errorCorrectionLevel, // Error Correction Level + maskPattern, // Calculated Mask pattern + segments // Generated segments +} +``` + +

+
+### wrapAnsi(string, columns, options?)
+
+Wrap words to the specified column width.
+
+#### string
+
+Type: `string`
+
+String with ANSI escape codes. Like one styled by [`chalk`](https://github.com/chalk/chalk). Newline characters will be normalized to `\n`.
+
+#### columns
+
+Type: `number`
+
+Number of columns to wrap the text to.
+
+#### options
+
+Type: `object`
+
+##### hard
+
+Type: `boolean`+Default: `false` + +By default the wrap is soft, meaning long words may extend past the column width. Setting this to `true` will make it hard wrap at the column width. + +##### wordWrap + +Type: `boolean`
+Default: `true` + +By default, an attempt is made to split words at spaces, ensuring that they don't extend past the configured columns. If wordWrap is `false`, each column will instead be completely filled splitting words as necessary. + +##### trim + +Type: `boolean`
+Default: `true` + +Whitespace on all lines is removed by default. Set this option to `false` if you don't want to trim. + + +## Related + +- [slice-ansi](https://github.com/chalk/slice-ansi) - Slice a string with ANSI escape codes +- [cli-truncate](https://github.com/sindresorhus/cli-truncate) - Truncate a string to a specific width in the terminal +- [chalk](https://github.com/chalk/chalk) - Terminal string styling done right +- [jsesc](https://github.com/mathiasbynens/jsesc) - Generate ASCII-only output from Unicode strings.

+[](https://conventionalcommits.org)
+
+The bare-bones internationalization library used by yargs.
+
+Inspired by [i18n](https://www.npmjs.com/package/i18n).
+
+## Examples
+
+_simple string translation:_
+
+```js
+var __ = require('y18n').__
+
+console.log(__('my awesome string %s', 'foo'))
+```
+
+output:
+
+`my awesome string foo`
+
+_using tagged template literals_
+
+```js
+var __ = require('y18n').__
+var str = 'foo'
+
+console.log(__`my awesome string ${str}`)
+```
+
+output:
+
+`my awesome string foo`
+
+_pluralization support:_
+
+```js
+var __n = require('y18n').__n
+
+console.log(__n('one fish %s', '%d fishes %s', 2, 'foo'))
+```
+
+output:
+
+`2 fishes foo`
+
+## JSON Language Files
+
+The JSON language files should be stored in a `./locales` folder.
+File names correspond to locales, e.g., `en.json`, `pirate.json`.
+
+When strings are observed for the first time they will be
+added to the JSON file corresponding to the current locale.
+
+## Methods
+
+### require('y18n')(config)
+
+Create an instance of y18n with the config provided, options include:
+
+* `directory`: the locale directory, default `./locales`.
+* `updateFiles`: should newly observed strings be updated in file, default `true`.
+* `locale`: what locale should be used.
+* `fallbackToLanguage`: should fallback to a language-only file (e.g. `en.json`)
+ be allowed if a file matching the locale does not exist (e.g. `en_US.json`),
+ default `true`.
+
+### y18n.\_\_(str, arg, arg, arg)
+
+Print a localized string, `%s` will be replaced with `arg`s.
+
+This function can also be used as a tag for a template literal. You can use it
+like this: + + Tidelift helps make open source sustainable for maintainers while giving companies
assurances about security, maintenance, and licensing for their dependencies. + +
__`hello ${'world'}`. This will be equivalent to
+`__('hello %s', 'world')`.
+
+### y18n.\_\_n(singularString, pluralString, count, arg, arg, arg)
+
+Print a localized string with appropriate pluralization. If `%d` is provided
+in the string, the `count` will replace this placeholder.
+
+### y18n.setLocale(str)
+
+Set the current locale being used.
+
+### y18n.getLocale()
+
+What locale is currently being used?
+
+### y18n.updateLocale(obj)
+
+Update the current locale with the key value pairs in `obj`.

+[](https://github.com/conventional-changelog/standard-version)
+
+
+The mighty option parser used by [yargs](https://github.com/yargs/yargs).
+
+visit the [yargs website](http://yargs.js.org/) for more examples, and thorough usage instructions.
+
+
+
+## Example
+
+```sh
+npm i yargs-parser --save
+```
+
+```js
+var argv = require('yargs-parser')(process.argv.slice(2))
+console.log(argv)
+```
+
+```sh
+node example.js --foo=33 --bar hello
+{ _: [], foo: 33, bar: 'hello' }
+```
+
+_or parse a string!_
+
+```js
+var argv = require('yargs-parser')('--foo=99 --bar=33')
+console.log(argv)
+```
+
+```sh
+{ _: [], foo: 99, bar: 33 }
+```
+
+Convert an array of mixed types before passing to `yargs-parser`:
+
+```js
+var parse = require('yargs-parser')
+parse(['-f', 11, '--zoom', 55].join(' ')) // <-- array to string
+parse(['-f', 11, '--zoom', 55].map(String)) // <-- array of strings
+```
+
+## API
+
+### require('yargs-parser')(args, opts={})
+
+Parses command line arguments returning a simple mapping of keys and values.
+
+**expects:**
+
+* `args`: a string or array of strings representing the options to parse.
+* `opts`: provide a set of hints indicating how `args` should be parsed:
+ * `opts.alias`: an object representing the set of aliases for a key: `{alias: {foo: ['f']}}`.
+ * `opts.array`: indicate that keys should be parsed as an array: `{array: ['foo', 'bar']}`.+ Indicate that keys should be parsed as an array and coerced to booleans / numbers:
+ `{array: [{ key: 'foo', boolean: true }, {key: 'bar', number: true}]}`. + * `opts.boolean`: arguments should be parsed as booleans: `{boolean: ['x', 'y']}`. + * `opts.coerce`: provide a custom synchronous function that returns a coerced value from the argument provided + (or throws an error). For arrays the function is called only once for the entire array:
+ `{coerce: {foo: function (arg) {return modifiedArg}}}`. + * `opts.config`: indicate a key that represents a path to a configuration file (this file will be loaded and parsed). + * `opts.configObjects`: configuration objects to parse, their properties will be set as arguments:
+ `{configObjects: [{'x': 5, 'y': 33}, {'z': 44}]}`. + * `opts.configuration`: provide configuration options to the yargs-parser (see: [configuration](#configuration)). + * `opts.count`: indicate a key that should be used as a counter, e.g., `-vvv` = `{v: 3}`. + * `opts.default`: provide default values for keys: `{default: {x: 33, y: 'hello world!'}}`. + * `opts.envPrefix`: environment variables (`process.env`) with the prefix provided should be parsed. + * `opts.narg`: specify that a key requires `n` arguments: `{narg: {x: 2}}`. + * `opts.normalize`: `path.normalize()` will be applied to values set to this key. + * `opts.number`: keys should be treated as numbers. + * `opts.string`: keys should be treated as strings (even if they resemble a number `-x 33`). + +**returns:** + +* `obj`: an object representing the parsed value of `args` + * `key/value`: key value pairs for each argument and their aliases. + * `_`: an array representing the positional arguments. + * [optional] `--`: an array with arguments after the end-of-options flag `--`. + +### require('yargs-parser').detailed(args, opts={}) + +Parses a command line string, returning detailed information required by the +yargs engine. + +**expects:** + +* `args`: a string or array of strings representing options to parse. +* `opts`: provide a set of hints indicating how `args`, inputs are identical to `require('yargs-parser')(args, opts={})`. + +**returns:** + +* `argv`: an object representing the parsed value of `args` + * `key/value`: key value pairs for each argument and their aliases. + * `_`: an array representing the positional arguments. + * [optional] `--`: an array with arguments after the end-of-options flag `--`. +* `error`: populated with an error object if an exception occurred during parsing. +* `aliases`: the inferred list of aliases built by combining lists in `opts.alias`. +* `newAliases`: any new aliases added via camel-case expansion: + * `boolean`: `{ fooBar: true }` +* `defaulted`: any new argument created by `opts.default`, no aliases included. + * `boolean`: `{ foo: true }` +* `configuration`: given by default settings and `opts.configuration`. + + + +### Configuration + +The yargs-parser applies several automated transformations on the keys provided +in `args`.

+ ++ +[![Build Status][travis-image]][travis-url] +[![NPM version][npm-image]][npm-url] +[![js-standard-style][standard-image]][standard-url] +[![Coverage][coverage-image]][coverage-url] +[![Conventional Commits][conventional-commits-image]][conventional-commits-url] +[![Slack][slack-image]][slack-url] + +## Description : +Yargs helps you build interactive command line tools, by parsing arguments and generating an elegant user interface. + +It gives you: + +* commands and (grouped) options (`my-program.js serve --port=5000`). +* a dynamically generated help menu based on your arguments. + +>
+
+* bash-completion shortcuts for commands and options.
+* and [tons more](/docs/api.md).
+
+## Installation

+## Usage :
+
+### Simple Example
+
+```javascript
+#!/usr/bin/env node
+const {argv} = require('yargs')
+
+if (argv.ships > 3 && argv.distance < 53.5) {
+ console.log('Plunder more riffiwobbles!')
+} else {
+ console.log('Retreat from the xupptumblers!')
+}
+```
+
+```bash
+$ ./plunder.js --ships=4 --distance=22
+Plunder more riffiwobbles!
+
+$ ./plunder.js --ships 12 --distance 98.7
+Retreat from the xupptumblers!
+```
+
+### Complex Example
+
+```javascript
+#!/usr/bin/env node
+require('yargs') // eslint-disable-line
+ .command('serve [port]', 'start the server', (yargs) => {
+ yargs
+ .positional('port', {
+ describe: 'port to bind on',
+ default: 5000
+ })
+ }, (argv) => {
+ if (argv.verbose) console.info(`start server on :${argv.port}`)
+ serve(argv.port)
+ })
+ .option('verbose', {
+ alias: 'v',
+ type: 'boolean',
+ description: 'Run with verbose logging'
+ })
+ .argv
+```
