## 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.

# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
## 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
### Modifiers
- `reset`
- `bold`
- `dim`
- `italic` *(Not widely supported)*
- `underline`
- `inverse`
- `hidden`
- `strikethrough` *(Not widely supported)*
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue`
- `magenta`
- `cyan`
- `white`
- `gray` ("bright black")
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`
- `cyanBright`
- `whiteBright`
### Background colors
- `bgBlack`
- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright`
- `bgRedBright`
- `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.
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
```

Sometimes you need to check if you're on _at least_ a given Node.js version, but you don't want to pull in the whole [`semver`](https://www.npmjs.com/package/semver) kitchen sink. That's what `at-least-node` is for.
| Package | Size |
| --------------- | ------- |
| `at-least-node` | 2.6 kB |
| `semver` | 75.5 kB |
```js
const atLeastNode = require('at-least-node')
atLeastNode('10.12.0')
// -> true on Node 10.12.0+, false on anything below that
```
When passing in a version string:
- You cannot include a leading `v` (i.e. `v10.12.0`)
- You cannot omit sections (i.e. `10.12`)
- You cannot use pre-releases (i.e. `1.0.0-beta`)
- There is no input validation, if you make a mistake, the resulting behavior is undefined

# balanced-match
Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
## Example
Get the first matching pair of braces:
```js
var balanced = require('balanced-match');
console.log(balanced('{', '}', 'pre{in{nested}}post'));
console.log(balanced('{', '}', 'pre{first}between{second}post'));
console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre { in{nest} } post'));
```
The matches are:
```bash
$ node example.js
{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
{ start: 3,
end: 9,
pre: 'pre',
body: 'first',
post: 'between{second}post' }
{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
```
## API
### var m = balanced(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
object with those keys:
* **start** the index of the first match of `a`
* **end** the index of the matching `b`
* **pre** the preamble, `a` and `b` not included
* **body** the match, `a` and `b` not included
* **post** the postscript, `a` and `b` not included
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
### var r = balanced.range(a, b, str)
For the first non-nested matching pair of `a` and `b` in `str`, return an
array with indexes: `[ <a index>, <b index> ]`.
If there's no match, `undefined` will be returned.
If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

base64-js
=========
`base64-js` does basic base64 encoding/decoding in pure JS.
[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](http://travis-ci.org/beatgammit/base64-js)
Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
## install
With [npm](https://npmjs.org) do:
`npm install base64-js` and `var base64js = require('base64-js')`
For use in web browsers do:
`<script src="base64js.min.js"></script>`
[Get supported base64-js with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-base64-js?utm_source=npm-base64-js&utm_medium=referral&utm_campaign=readme)
## methods
`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
* `byteLength` - Takes a base64 string and returns length of byte array
* `toByteArray` - Takes a base64 string and returns a byte array
* `fromByteArray` - Takes a byte array and returns a base64 string

# bl *(BufferList)*
[![Build Status](https://api.travis-ci.com/rvagg/bl.svg?branch=master)](https://travis-ci.com/rvagg/bl/)
**A Node.js Buffer list collector, reader and streamer thingy.**
[![NPM](https://nodei.co/npm/bl.svg)](https://nodei.co/npm/bl/)
**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
```js
const { BufferList } = require('bl')
const bl = new BufferList()
bl.append(Buffer.from('abcd'))
bl.append(Buffer.from('efg'))
bl.append('hi') // bl will also accept & convert Strings
bl.append(Buffer.from('j'))
bl.append(Buffer.from([ 0x3, 0x4 ]))
console.log(bl.length) // 12
console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
console.log(bl.slice(3, 6).toString('ascii')) // 'def'
console.log(bl.slice(3, 8).toString('ascii')) // 'defgh'
console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
console.log(bl.indexOf('def')) // 3
console.log(bl.indexOf('asdf')) // -1
// or just use toString!
console.log(bl.toString()) // 'abcdefghij\u0003\u0004'
console.log(bl.toString('ascii', 3, 8)) // 'defgh'
console.log(bl.toString('ascii', 5, 10)) // 'fghij'
// other standard Buffer readables
console.log(bl.readUInt16BE(10)) // 0x0304
console.log(bl.readUInt16LE(10)) // 0x0403
```
Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
```js
const { BufferListStream } = require('bl')
const fs = require('fs')
fs.createReadStream('README.md')
.pipe(BufferListStream((err, data) => { // note 'new' isn't strictly required
// `data` is a complete Buffer object containing the full data
console.log(data.toString())
}))
```
Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
```js
const hyperquest = require('hyperquest')
const { BufferListStream } = require('bl')
const url = 'https://raw.github.com/rvagg/bl/master/README.md'
hyperquest(url).pipe(BufferListStream((err, data) => {
console.log(data.toString())
}))
```
Or, use it as a readable stream to recompose a list of Buffers to an output source:
```js
const { BufferListStream } = require('bl')
const fs = require('fs')
var bl = new BufferListStream()
bl.append(Buffer.from('abcd'))
bl.append(Buffer.from('efg'))
bl.append(Buffer.from('hi'))
bl.append(Buffer.from('j'))
bl.pipe(fs.createWriteStream('gibberish.txt'))
```

### new BufferList([ Buffer | Buffer array | BufferList | BufferList array | String ])
No arguments are _required_ for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` objects.
`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
```js
const { BufferList } = require('bl')
const bl = BufferList()
// equivalent to:
const { BufferList } = require('bl')
const bl = new BufferList()
```
--------------------------------------------------------
<a name="isBufferList"></a>
### BufferList.isBufferList(obj)
Determines if the passed object is a `BufferList`. It will return `true` if the passed object is an instance of `BufferList` **or** `BufferListStream` and `false` otherwise.
N.B. this won't return `true` for `BufferList` or `BufferListStream` instances created by versions of this library before this static method was added.
--------------------------------------------------------
<a name="length"></a>
### bl.length
Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
--------------------------------------------------------
<a name="append"></a>
### bl.append(Buffer | Buffer array | BufferList | BufferList array | String)
`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained.
--------------------------------------------------------
<a name="get"></a>
### bl.get(index)
`get()` will return the byte at the specified index.
--------------------------------------------------------
<a name="indexOf"></a>
### bl.indexOf(value[, byteOffset][, encoding])
`get()` will return the byte at the specified index.
`indexOf()` method returns the first index at which a given element can be found in the BufferList, or -1 if it is not present.
--------------------------------------------------------
<a name="slice"></a>
### bl.slice([ start, [ end ] ])
`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
--------------------------------------------------------
<a name="shallowSlice"></a>
### bl.shallowSlice([ start, [ end ] ])
`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
No copies will be performed. All buffers in the result share memory with the original list.
--------------------------------------------------------
<a name="copy"></a>
### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
--------------------------------------------------------
<a name="duplicate"></a>
### bl.duplicate()
`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
```js
var bl = new BufferListStream()
bl.append('hello')
bl.append(' world')
bl.append('\n')
bl.duplicate().pipe(process.stdout, { end: false })
console.log(bl.toString())
```
--------------------------------------------------------
<a name="consume"></a>
### bl.consume(bytes)
`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers&mdash;initial offsets will be calculated accordingly in order to give you a consistent view of the data.
--------------------------------------------------------
<a name="toString"></a>
### bl.toString([encoding, [ start, [ end ]]])
`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
--------------------------------------------------------
<a name="readXX"></a>
### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
--------------------------------------------------------
<a name="ctorStream"></a>
### new BufferListStream([ callback | Buffer | Buffer array | BufferList | BufferList array | String ])
**BufferListStream** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **BufferListStream** instance.
The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
```js
const { BufferListStream } = require('bl')
const bl = BufferListStream()
// equivalent to:
const { BufferListStream } = require('bl')
const bl = new BufferListStream()
```
N.B. For backwards compatibility reasons, `BufferListStream` is the **default** export when you `require('bl')`:
```js
const { BufferListStream } = require('bl')
// equivalent to:
const BufferListStream = require('bl')
```

# brace-expansion
[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html),
as known from sh/bash, in JavaScript.
[![build status](https://secure.travis-ci.org/juliangruber/brace-expansion.svg)](http://travis-ci.org/juliangruber/brace-expansion)
[![downloads](https://img.shields.io/npm/dm/brace-expansion.svg)](https://www.npmjs.org/package/brace-expansion)
[![Greenkeeper badge](https://badges.greenkeeper.io/juliangruber/brace-expansion.svg)](https://greenkeeper.io/)
[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
## Example
```js
var expand = require('brace-expansion');
expand('file-{a,b,c}.jpg')
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
expand('-v{,,}')
// => ['-v', '-v', '-v']
expand('file{0..2}.jpg')
// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
expand('file-{a..c}.jpg')
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
expand('file{2..0}.jpg')
// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
expand('file{0..4..2}.jpg')
// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
expand('file-{a..e..2}.jpg')
// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
expand('file{00..10..5}.jpg')
// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
expand('{{A..C},{a..c}}')
// => ['A', 'B', 'C', 'a', 'b', 'c']
expand('ppp{,config,oe{,conf}}')
// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
```
## API
```js
var expand = require('brace-expansion');
```
### var expanded = expand(str)
Return an array of all possible and valid expansions of `str`. If none are
found, `[str]` is returned.
Valid expansions are:
```js
/^(.*,)+(.+)?$/
// {a,b,...}
```
A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
```js
/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
// {x..y[..incr]}
```
A numeric sequence from `x` to `y` inclusive, with optional increment.
If `x` or `y` start with a leading `0`, all the numbers will be padded
to have equal length. Negative numbers and backwards iteration work too.
```js
/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
// {x..y[..incr]}
```
An alphabetic sequence from `x` to `y` inclusive, with optional increment.
`x` and `y` must be exactly one character, and if given, `incr` must be a
number.
For compatibility reasons, the string `${` is not eligible for brace expansion.
## Installation
With [npm](https://npmjs.org) do:
```bash
npm install brace-expansion
```

> Bash-like brace expansion, implemented in JavaScript. Safer than other brace expansion libs, with complete support for the Bash 4.3 braces specification, without sacrificing speed.
Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save braces
```
## v3.0.0 Released!!
See the [changelog](CHANGELOG.md) for details.
## Why use braces?
Brace patterns make globs more powerful by adding the ability to match specific ranges and sequences of characters.
* **Accurate** - complete support for the [Bash 4.3 Brace Expansion](www.gnu.org/software/bash/) specification (passes all of the Bash braces tests)
* **[fast and performant](#benchmarks)** - Starts fast, runs fast and [scales well](#performance) as patterns increase in complexity.
* **Organized code base** - The parser and compiler are easy to maintain and update when edge cases crop up.
* **Well-tested** - Thousands of test assertions, and passes all of the Bash, minimatch, and [brace-expansion](https://github.com/juliangruber/brace-expansion) unit tests (as of the date this was written).
* **Safer** - You shouldn't have to worry about users defining aggressive or malicious brace patterns that can break your application. Braces takes measures to prevent malicious regex that can be used for DDoS attacks (see [catastrophic backtracking](https://www.regular-expressions.info/catastrophic.html)).
* [Supports lists](#lists) - (aka "sets") `a/{b,c}/d` => `['a/b/d', 'a/c/d']`
* [Supports sequences](#sequences) - (aka "ranges") `{01..03}` => `['01', '02', '03']`
* [Supports steps](#steps) - (aka "increments") `{2..10..2}` => `['2', '4', '6', '8', '10']`
* [Supports escaping](#escaping) - To prevent evaluation of special characters.
## Usage
The main export is a function that takes one or more brace `patterns` and `options`.
```js
const braces = require('braces');
// braces(patterns[, options]);
console.log(braces(['{01..05}', '{a..e}']));
//=> ['(0[1-5])', '([a-e])']
console.log(braces(['{01..05}', '{a..e}'], { expand: true }));
//=> ['01', '02', '03', '04', '05', 'a', 'b', 'c', 'd', 'e']
```
### Brace Expansion vs. Compilation
By default, brace patterns are compiled into strings that are optimized for creating regular expressions and matching.
**Compiled**
```js
console.log(braces('a/{x,y,z}/b'));
//=> ['a/(x|y|z)/b']
console.log(braces(['a/{01..20}/b', 'a/{1..5}/b']));
//=> [ 'a/(0[1-9]|1[0-9]|20)/b', 'a/([1-5])/b' ]
```
**Expanded**
Enable brace expansion by setting the `expand` option to true, or by using [braces.expand()](#expand) (returns an array similar to what you'd expect from Bash, or `echo {1..5}`, or [minimatch](https://github.com/isaacs/minimatch)):
```js
console.log(braces('a/{x,y,z}/b', { expand: true }));
//=> ['a/x/b', 'a/y/b', 'a/z/b']
console.log(braces.expand('{01..10}'));
//=> ['01','02','03','04','05','06','07','08','09','10']
```
### Lists
Expand lists (like Bash "sets"):
```js
console.log(braces('a/{foo,bar,baz}/*.js'));
//=> ['a/(foo|bar|baz)/*.js']
console.log(braces.expand('a/{foo,bar,baz}/*.js'));
//=> ['a/foo/*.js', 'a/bar/*.js', 'a/baz/*.js']
```
### Sequences
Expand ranges of characters (like Bash "sequences"):
```js
console.log(braces.expand('{1..3}')); // ['1', '2', '3']
console.log(braces.expand('a/{1..3}/b')); // ['a/1/b', 'a/2/b', 'a/3/b']
console.log(braces('{a..c}', { expand: true })); // ['a', 'b', 'c']
console.log(braces('foo/{a..c}', { expand: true })); // ['foo/a', 'foo/b', 'foo/c']
// supports zero-padded ranges
console.log(braces('a/{01..03}/b')); //=> ['a/(0[1-3])/b']
console.log(braces('a/{001..300}/b')); //=> ['a/(0{2}[1-9]|0[1-9][0-9]|[12][0-9]{2}|300)/b']
```
See [fill-range](https://github.com/jonschlinkert/fill-range) for all available range-expansion options.
### Steppped ranges
Steps, or increments, may be used with ranges:
```js
console.log(braces.expand('{2..10..2}'));
//=> ['2', '4', '6', '8', '10']
console.log(braces('{2..10..2}'));
//=> ['(2|4|6|8|10)']
```
When the [.optimize](#optimize) method is used, or [options.optimize](#optionsoptimize) is set to true, sequences are passed to [to-regex-range](https://github.com/jonschlinkert/to-regex-range) for expansion.
### Nesting
Brace patterns may be nested. The results of each expanded string are not sorted, and left to right order is preserved.
**"Expanded" braces**
```js
console.log(braces.expand('a{b,c,/{x,y}}/e'));
//=> ['ab/e', 'ac/e', 'a/x/e', 'a/y/e']
console.log(braces.expand('a/{x,{1..5},y}/c'));
//=> ['a/x/c', 'a/1/c', 'a/2/c', 'a/3/c', 'a/4/c', 'a/5/c', 'a/y/c']
```
**"Optimized" braces**
```js
console.log(braces('a{b,c,/{x,y}}/e'));
//=> ['a(b|c|/(x|y))/e']
console.log(braces('a/{x,{1..5},y}/c'));
//=> ['a/(x|([1-5])|y)/c']
```
### Escaping
**Escaping braces**
A brace pattern will not be expanded or evaluted if _either the opening or closing brace is escaped_:
```js
console.log(braces.expand('a\\{d,c,b}e'));
//=> ['a{d,c,b}e']
console.log(braces.expand('a{d,c,b\\}e'));
//=> ['a{d,c,b}e']
```
**Escaping commas**
Commas inside braces may also be escaped:
```js
console.log(braces.expand('a{b\\,c}d'));
//=> ['a{b,c}d']
console.log(braces.expand('a{d\\,c,b}e'));
//=> ['ad,ce', 'abe']
```
**Single items**
Following bash conventions, a brace pattern is also not expanded when it contains a single character:
```js
console.log(braces.expand('a{b}c'));
//=> ['a{b}c']
```
## Options
### options.maxLength
**Type**: `Number`
**Default**: `65,536`
**Description**: Limit the length of the input string. Useful when the input string is generated or your application allows users to pass a string, et cetera.
```js
console.log(braces('a/{b,c}/d', { maxLength: 3 })); //=> throws an error
```
### options.expand
**Type**: `Boolean`
**Default**: `undefined`
**Description**: Generate an "expanded" brace pattern (alternatively you can use the `braces.expand()` method, which does the same thing).
```js
console.log(braces('a/{b,c}/d', { expand: true }));
//=> [ 'a/b/d', 'a/c/d' ]
```
### options.nodupes
**Type**: `Boolean`
**Default**: `undefined`
**Description**: Remove duplicates from the returned array.
### options.rangeLimit
**Type**: `Number`
**Default**: `1000`
**Description**: To prevent malicious patterns from being passed by users, an error is thrown when `braces.expand()` is used or `options.expand` is true and the generated range will exceed the `rangeLimit`.
You can customize `options.rangeLimit` or set it to `Inifinity` to disable this altogether.
**Examples**
```js
// pattern exceeds the "rangeLimit", so it's optimized automatically
console.log(braces.expand('{1..1000}'));
//=> ['([1-9]|[1-9][0-9]{1,2}|1000)']
// pattern does not exceed "rangeLimit", so it's NOT optimized
console.log(braces.expand('{1..100}'));
//=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62', '63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74', '75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86', '87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', '98', '99', '100']
```
### options.transform
**Type**: `Function`
**Default**: `undefined`
**Description**: Customize range expansion.
**Example: Transforming non-numeric values**
```js
const alpha = braces.expand('x/{a..e}/y', {
transform(value, index) {
// When non-numeric values are passed, "value" is a character code.
return 'foo/' + String.fromCharCode(value) + '-' + index;
}
});
console.log(alpha);
//=> [ 'x/foo/a-0/y', 'x/foo/b-1/y', 'x/foo/c-2/y', 'x/foo/d-3/y', 'x/foo/e-4/y' ]
```
**Example: Transforming numeric values**
```js
const numeric = braces.expand('{1..5}', {
transform(value) {
// when numeric values are passed, "value" is a number
return 'foo/' + value * 2;
}
});
console.log(numeric);
//=> [ 'foo/2', 'foo/4', 'foo/6', 'foo/8', 'foo/10' ]
```
### options.quantifiers
**Type**: `Boolean`
**Default**: `undefined`
**Description**: In regular expressions, quanitifiers can be used to specify how many times a token can be repeated. For example, `a{1,3}` will match the letter `a` one to three times.
Unfortunately, regex quantifiers happen to share the same syntax as [Bash lists](#lists)
The `quantifiers` option tells braces to detect when [regex quantifiers](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp#quantifiers) are defined in the given pattern, and not to try to expand them as lists.
**Examples**
```js
const braces = require('braces');
console.log(braces('a/b{1,3}/{x,y,z}'));
//=> [ 'a/b(1|3)/(x|y|z)' ]
console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true}));
//=> [ 'a/b{1,3}/(x|y|z)' ]
console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true, expand: true}));
//=> [ 'a/b{1,3}/x', 'a/b{1,3}/y', 'a/b{1,3}/z' ]
```
### options.unescape
**Type**: `Boolean`
**Default**: `undefined`
**Description**: Strip backslashes that were used for escaping from the result.
## What is "brace expansion"?
Brace expansion is a type of parameter expansion that was made popular by unix shells for generating lists of strings, as well as regex-like matching when used alongside wildcards (globs).
In addition to "expansion", braces are also used for matching. In other words:
* [brace expansion](#brace-expansion) is for generating new lists
* [brace matching](#brace-matching) is for filtering existing lists
<details>
<summary><strong>More about brace expansion</strong> (click to expand)</summary>
There are two main types of brace expansion:
1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}`
2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges".
Here are some example brace patterns to illustrate how they work:
**Sets**
```
{a,b,c} => a b c
{a,b,c}{1,2} => a1 a2 b1 b2 c1 c2
```
**Sequences**
```
{1..9} => 1 2 3 4 5 6 7 8 9
{4..-4} => 4 3 2 1 0 -1 -2 -3 -4
{1..20..3} => 1 4 7 10 13 16 19
{a..j} => a b c d e f g h i j
{j..a} => j i h g f e d c b a
{a..z..3} => a d g j m p s v y
```
**Combination**
Sets and sequences can be mixed together or used along with any other strings.
```
{a,b,c}{1..3} => a1 a2 a3 b1 b2 b3 c1 c2 c3
foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar
```
The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases.
## Brace matching
In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching.
For example, the pattern `foo/{1..3}/bar` would match any of following strings:
```
foo/1/bar
foo/2/bar
foo/3/bar
```
But not:
```
baz/1/qux
baz/2/qux
baz/3/qux
```
Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings:
```
foo/1/bar
foo/2/bar
foo/3/bar
baz/1/qux
baz/2/qux
baz/3/qux
```
## Brace matching pitfalls
Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of.
### tldr
**"brace bombs"**
* brace expansion can eat up a huge amount of processing resources
* as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially
* users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!)
For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section.
### The solution
Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries.
### Geometric complexity
At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`.
For example, the following sets demonstrate quadratic (`O(n^2)`) complexity:
```
{1,2}{3,4} => (2X2) => 13 14 23 24
{1,2}{3,4}{5,6} => (2X2X2) => 135 136 145 146 235 236 245 246
```
But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity:
```
{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248
249 257 258 259 267 268 269 347 348 349 357
358 359 367 368 369
```
Now, imagine how this complexity grows given that each element is a n-tuple:
```
{1..100}{1..100} => (100X100) => 10,000 elements (38.4 kB)
{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB)
```
Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control.

## Performance
Braces is not only screaming fast, it's also more accurate the other brace expansion libraries.
### Better algorithms
Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_.
Instead, convert the pattern into an optimized regular expression. This is easier said than done, and braces is the only library that does this currently.
**The proof is in the numbers**
Minimatch gets exponentially slower as patterns increase in complexity, braces does not. The following results were generated using `braces()` and `minimatch.braceExpand()`, respectively.
| **Pattern** | **braces** | **[minimatch][]** |
| --- | --- | --- |
| `{1..9007199254740991}`[^1] | `298 B` (5ms 459μs)| N/A (freezes) |
| `{1..1000000000000000}` | `41 B` (1ms 15μs) | N/A (freezes) |
| `{1..100000000000000}` | `40 B` (890μs) | N/A (freezes) |
| `{1..10000000000000}` | `39 B` (2ms 49μs) | N/A (freezes) |

| `{1..100000}` | `30 B` (950μs) | `588.89 kB` (146ms 921μs) |
| `{1..10000}` | `29 B` (1ms 114μs) | `48.89 kB` (14ms 187μs) |
| `{1..1000}` | `28 B` (760μs) | `3.89 kB` (1ms 453μs) |
| `{1..100}` | `22 B` (345μs) | `291 B` (196μs) |
| `{1..10}` | `10 B` (533μs) | `20 B` (37μs) |
| `{1..3}` | `7 B` (190μs) | `5 B` (27μs) |
### Faster algorithms
When you need expansion, braces is still much faster.
_(the following results were generated using `braces.expand()` and `minimatch.braceExpand()`, respectively)_
| **Pattern** | **braces** | **[minimatch][]** |
| --- | --- | --- |
| `{1..10000000}` | `78.89 MB` (2s 698ms 642μs) | `78.89 MB` (18s 601ms 974μs) |
| `{1..1000000}` | `6.89 MB` (458ms 576μs) | `6.89 MB` (1s 491ms 621μs) |
| `{1..100000}` | `588.89 kB` (20ms 728μs) | `588.89 kB` (156ms 919μs) |
| `{1..10000}` | `48.89 kB` (2ms 202μs) | `48.89 kB` (13ms 641μs) |
| `{1..1000}` | `3.89 kB` (1ms 796μs) | `3.89 kB` (1ms 958μs) |
| `{1..100}` | `291 B` (424μs) | `291 B` (211μs) |
| `{1..10}` | `20 B` (487μs) | `20 B` (72μs) |
| `{1..3}` | `5 B` (166μs) | `5 B` (27μs) |

#### The buffer module from [node.js](https://nodejs.org/), for the browser.
[![saucelabs][saucelabs-image]][saucelabs-url]
[saucelabs-image]: https://saucelabs.com/browser-matrix/buffer.svg
[saucelabs-url]: https://saucelabs.com/u/buffer
With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
The goal is to provide an API that is 100% identical to
[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.
## features
- Manipulate binary data like a boss, in all browsers!
- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
- Excellent browser support (Chrome, Firefox, Edge, Safari 9+, IE 11, iOS 9+, Android, etc.)
- Preserves Node API exactly, with one minor difference (see below)
- Square-bracket `buf[4]` notation works!
- Does not modify any browser prototypes or put anything on `window`
- Comprehensive test suite (including all buffer tests from node.js core)
## install
To use this module directly (without browserify), install it:
```bash
npm install buffer
```
This module was previously called **native-buffer-browserify**, but please use **buffer**
from now on.
If you do not use a bundler, you can use the [standalone script](https://bundle.run/buffer).
## usage
The module's API is identical to node's `Buffer` API. Read the
[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
instance methods, and class methods that are supported.
As mentioned above, `require('buffer')` or use the `Buffer` global with
[browserify](http://browserify.org) and this module will automatically be included
in your bundle. Almost any npm module will work in the browser, even if it assumes that
the node `Buffer` API will be available.
To depend on this module explicitly (without browserify), require it like this:
```js
var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
```
To require this module explicitly, use `require('buffer/')` which tells the node.js module
lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
instead of the **node.js core** module named `buffer`!
## how does it work?
The Buffer constructor returns instances of `Uint8Array` that have their prototype
changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
so the returned instances will have all the node `Buffer` methods and the
`Uint8Array` methods. Square bracket notation works as expected -- it returns a
single octet.
The `Uint8Array` prototype remains unmodified.
## tracking the latest node api
This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
API is considered **stable** in the
[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
so it is unlikely that there will ever be breaking changes.
Nonetheless, when/if the Buffer API changes in node, this module's API will change
accordingly.
## related packages
- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer
- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer
- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package
## conversion packages
### convert typed array to buffer
Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
### convert buffer to typed array
`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
### convert blob to buffer
Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
### convert buffer to blob
To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
```js
var blob = new Blob([ buffer ])
```
Optionally, specify a mimetype:
```js
var blob = new Blob([ buffer ], { type: 'text/html' })
```
### convert arraybuffer to buffer
To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
```js
var buffer = Buffer.from(arrayBuffer)
```
### convert buffer to arraybuffer
To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
```js
var arrayBuffer = buffer.buffer.slice(
buffer.byteOffset, buffer.byteOffset + buffer.byteLength
)
```
Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
## performance
See perf tests in `/perf`.
`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
which is included to compare against.
NOTE: Performance has improved since these benchmarks were taken. PR welcome to update the README.

## Testing the project
First, install the project:
npm install
Then, to run tests in Node.js, run:
npm run test-node
To test locally in a browser, you can run:
npm run test-browser-es5-local # For ES5 browsers that don't support ES6
npm run test-browser-es6-local # For ES6 compliant browsers
This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap).
To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
npm test
This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files.
## JavaScript Standard Style
This module uses [JavaScript Standard Style](https://github.com/feross/standard).
[![JavaScript Style Guide](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
To test that the code conforms to the style, `npm install` and run:
./node_modules/.bin/standard

## Usage
```js
const chalk = require('chalk');
console.log(chalk.blue('Hello world!'));
```
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
```js
const chalk = require('chalk');
const log = console.log;
// Combine styled and normal strings
log(chalk.blue('Hello') + ' World' + chalk.red('!'));
// Compose multiple styles using the chainable API
log(chalk.blue.bgRed.bold('Hello world!'));
// Pass in multiple arguments
log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
// Nest styles
log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
// Nest styles of the same type even (color, underline, background)
log(chalk.green(
'I am a green line ' +
chalk.blue.underline.bold('with a blue substring') +
' that becomes green again!'
));
// ES2015 template literal
log(`
CPU: ${chalk.red('90%')}
RAM: ${chalk.green('40%')}
DISK: ${chalk.yellow('70%')}
`);
// ES2015 tagged template literal
log(chalk`
CPU: {red ${cpu.totalPercent}%}
RAM: {green ${ram.used / ram.total * 100}%}
DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
`);
// Use RGB colors in terminal emulators that support it.
log(chalk.keyword('orange')('Yay for orange colored text!'));
log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
log(chalk.hex('#DEADED').bold('Bold gray!'));
```
Easily define your own themes:
```js
const chalk = require('chalk');
const error = chalk.bold.red;
const warning = chalk.keyword('orange');
console.log(error('Error!'));
console.log(warning('Warning!'));
```
Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
```js
const name = 'Sindre';
console.log(chalk.green('Hello %s'), name);
//=> 'Hello Sindre'
```
## API
### chalk.`<style>[.<style>...](string, [string...])`
Example: `chalk.red.bold.underline('Hello', 'world');`
Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
Multiple arguments will be separated by space.
### chalk.enabled
Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
Chalk is enabled by default unless explicitly disabled via the constructor or `chalk.level` is `0`.
If you need to change this in a reusable module, create a new instance:
```js
const ctx = new chalk.constructor({enabled: false});
```
### chalk.level
Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
If you need to change this in a reusable module, create a new instance:
```js
const ctx = new chalk.constructor({level: 0});
```
Levels are as follows:
0. All colors disabled
1. Basic color support (16 colors)
2. 256 color support
3. Truecolor support (16 million colors)
### chalk.supportsColor
Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
## Styles
### Modifiers
- `reset`
- `bold`
- `dim`
- `italic` *(Not widely supported)*
- `underline`
- `inverse`
- `hidden`
- `strikethrough` *(Not widely supported)*
- `visible` (Text is emitted only if enabled)
### Colors
- `black`
- `red`
- `green`
- `yellow`
- `blue` *(On Windows the bright version is used since normal blue is illegible)*
- `magenta`
- `cyan`
- `white`
- `gray` ("bright black")
- `redBright`
- `greenBright`
- `yellowBright`
- `blueBright`
- `magentaBright`

- `bgRed`
- `bgGreen`
- `bgYellow`
- `bgBlue`
- `bgMagenta`
- `bgCyan`
- `bgWhite`
- `bgBlackBright`

- `bgGreenBright`
- `bgYellowBright`
- `bgBlueBright`
- `bgMagentaBright`
- `bgCyanBright`
- `bgWhiteBright`
## Tagged template literal
Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
```js
const chalk = require('chalk');
const miles = 18;
const calculateFeet = miles => miles * 5280;
console.log(chalk`
There are {bold 5280 feet} in a mile.
In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
`);
```
Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
```js
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
```
Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
## 256 and Truecolor color support
Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
Examples:
- `chalk.hex('#DEADED').underline('Hello, world!')`
- `chalk.keyword('orange')('Some orange text')`
- `chalk.rgb(15, 100, 204).inverse('Hello!')`
Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
- `chalk.bgHex('#DEADED').underline('Hello, world!')`
- `chalk.bgKeyword('orange')('Some orange text')`
- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
The following color models can be used:
- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
- `ansi16`
- `ansi256`
## Windows
If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
## Origin story
[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

chardet [![Build Status](https://travis-ci.org/runk/node-chardet.png)](https://travis-ci.org/runk/node-chardet)
=====
Chardet is a character detection module for NodeJS written in pure Javascript.
Module is based on ICU project http://site.icu-project.org/, which uses character
occurency analysis to determine the most probable encoding.
## Installation
```
npm i chardet
```
## Usage
To return the encoding with the highest confidence:
```javascript
var chardet = require('chardet');
chardet.detect(Buffer.alloc('hello there!'));
// or
chardet.detectFile('/path/to/file', function(err, encoding) {});
// or
chardet.detectFileSync('/path/to/file');
```
To return the full list of possible encodings:
```javascript
var chardet = require('chardet');
chardet.detectAll(Buffer.alloc('hello there!'));
// or
chardet.detectFileAll('/path/to/file', function(err, encoding) {});
// or
chardet.detectFileAllSync('/path/to/file');
//Returned value is an array of objects sorted by confidence value in decending order
//e.g. [{ confidence: 90, name: 'UTF-8'}, {confidence: 20, name: 'windows-1252', lang: 'fr'}]
```
## Working with large data sets
Sometimes, when data set is huge and you want to optimize performace (in tradeoff of less accuracy),
you can sample only first N bytes of the buffer:
```javascript
chardet.detectFile('/path/to/file', { sampleSize: 32 }, function(err, encoding) {});
```
## Supported Encodings:
* UTF-8
* UTF-16 LE
* UTF-16 BE
* UTF-32 LE
* UTF-32 BE
* ISO-2022-JP
* ISO-2022-KR
* ISO-2022-CN
* Shift-JIS
* Big5
* EUC-JP
* EUC-KR
* GB18030
* ISO-8859-1
* ISO-8859-2
* ISO-8859-5
* ISO-8859-6
* ISO-8859-7
* ISO-8859-8
* ISO-8859-9
* windows-1250
* windows-1251
* windows-1252
* windows-1253
* windows-1254
* windows-1255
* windows-1256
* KOI8-R
Currently only these encodings are supported, more will be added soon.

# cli-spinners
> 70+ spinners for use in the terminal
<p align="center">
<br>
<img width="700" src="screenshot.svg">

<br>
</p>
The list of spinners is just a [JSON file](spinners.json) and can be used wherever.
You probably want to use one of these spinners through the [`ora`](https://github.com/sindresorhus/ora) module.
## Install
```sh
npm install cli-spinners
```
## Usage
```js
const cliSpinners = require('cli-spinners');
console.log(cliSpinners.dots);
/*
{
interval: 80,
frames: ['⠋', '⠙', '⠹', '⠸', '⠼', '⠴', '⠦', '⠧', '⠇', '⠏']
}
*/
```
## Preview
The header GIF is outdated. See all the [spinner at once](https://jsfiddle.net/sindresorhus/2eLtsbey/embedded/result/) or [one at the time](https://asciinema.org/a/95348?size=big).
## API
Each spinner comes with a recommended `interval` and an array of `frames`.
[See the spinners.](spinners.json)
The `random` spinner will return a random spinner each time it's called.
