# webpack-dev-server
Use [webpack](https://webpack.js.org) with a development server that provides
live reloading. This should be used for **development only**.
It uses [webpack-dev-middleware][middleware-url] under the hood, which provides
fast in-memory access to the webpack assets.

- [The Result](#the-result)
- [Browser Support](#browser-support)
- [Support](#support)
- [Contributing](#contributing)
- [Attribution](#attribution)
- [License](#license)
## Getting Started
First things first, install the module:
```console
npm install webpack-dev-server --save-dev
```
_Note: While you can install and run webpack-dev-server globally, we recommend
installing it locally. webpack-dev-server will always use a local installation
over a global one._
## Usage
There are two main, recommended methods of using the module:
### With the CLI
The easiest way to use it is with the CLI. In the directory where your
`webpack.config.js` is, run:
```console
node_modules/.bin/webpack-dev-server
```
_**Note**: Many CLI options are available with `webpack-dev-server`. Explore this [link](https://webpack.js.org/configuration/dev-server/)._
### With NPM Scripts
NPM package.json scripts are a convenient and useful means to run locally installed
binaries without having to be concerned about their full paths. Simply define a
script as such:
```json
"scripts": {
"start:dev": "webpack-dev-server"
}
```
And run the following in your terminal/console:
```console
npm run start:dev
```
NPM will automagically reference the binary in `node_modules` for you, and
execute the file or command.
### The Result
Either method will start a server instance and begin listening for connections
from `localhost` on port `8080`.
webpack-dev-server is configured by default to support live-reload of files as
you edit your assets while the server is running.
See [**the documentation**][docs-url] for more use cases and options.
## Browser Support
While `webpack-dev-server` transpiles the client (browser) scripts to an ES5
state, the project only officially supports the _last two versions of major
browsers_. We simply don't have the resources to support every whacky
browser out there.
If you find a bug with an obscure / old browser, we would actively welcome a
Pull Request to resolve the bug.
## Support
We do our best to keep Issues in the repository focused on bugs, features, and
needed modifications to the code for the module. Because of that, we ask users
with general support, "how-to", or "why isn't this working" questions to try one
of the other support channels that are available.
Your first-stop-shop for support for webpack-dev-server should by the excellent
[documentation][docs-url] for the module. If you see an opportunity for improvement
of those docs, please head over to the [webpack.js.org repo][wjo-url] and open a
pull request.
From there, we encourage users to visit the [webpack Gitter chat][chat-url] and
talk to the fine folks there. If your quest for answers comes up dry in chat,
head over to [StackOverflow][stack-url] and do a quick search or open a new
question. Remember; It's always much easier to answer questions that include your
`webpack.config.js` and relevant files!
If you're twitter-savvy you can tweet [#webpack][hash-url] with your question
and someone should be able to reach out and lend a hand.
If you have discovered a :bug:, have a feature suggestion, or would like to see
a modification, please feel free to create an issue on Github. _Note: The issue
template isn't optional, so please be sure not to remove it, and please fill it
out completely._

# ansi-regex [![Build Status](https://travis-ci.org/chalk/ansi-regex.svg?branch=master)](https://travis-ci.org/chalk/ansi-regex)
> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
## Install
```
$ npm install --save ansi-regex
```
## Usage
```js
const ansiRegex = require('ansi-regex');
ansiRegex().test('\u001b[4mcake\u001b[0m');
//=> true
ansiRegex().test('cake');
//=> false
'\u001b[4mcake\u001b[0m'.match(ansiRegex());
//=> ['\u001b[4m', '\u001b[0m']
```
## 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. 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.

# 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
```

anymatch [![Build Status](https://travis-ci.org/micromatch/anymatch.svg?branch=master)](https://travis-ci.org/micromatch/anymatch) [![Coverage Status](https://img.shields.io/coveralls/micromatch/anymatch.svg?branch=master)](https://coveralls.io/r/micromatch/anymatch?branch=master)
======
Javascript module to match a string against a regular expression, glob, string,
or function that takes the string as an argument and returns a truthy or falsy
value. The matcher can also be an array of any or all of these. Useful for
allowing a very flexible user-defined config to define things like file paths.
__Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See https://github.com/micromatch/micromatch#backslashes for more information.__

[![NPM](https://nodei.co/npm-dl/anymatch.png?height=3&months=9)](https://nodei.co/npm-dl/anymatch/)
Usage
-----
```sh
npm install anymatch --save
```
#### anymatch (matchers, testString, [returnIndex], [startIndex], [endIndex])
* __matchers__: (_Array|String|RegExp|Function_)
String to be directly matched, string with glob patterns, regular expression
test, function that takes the testString as an argument and returns a truthy
value if it should be matched, or an array of any number and mix of these types.
* __testString__: (_String|Array_) The string to test against the matchers. If
passed as an array, the first element of the array will be used as the
`testString` for non-function matchers, while the entire array will be applied
as the arguments for function matchers.
* __returnIndex__: (_Boolean [optional]_) If true, return the array index of
the first matcher that that testString matched, or -1 if no match, instead of a
boolean result.
* __startIndex, endIndex__: (_Integer [optional]_) Can be used to define a
subset out of the array of provided matchers to test against. Can be useful
with bound matcher functions (see below). When used with `returnIndex = true`
preserves original indexing. Behaves the same as `Array.prototype.slice` (i.e.
includes array members up to, but not including endIndex).
```js
var anymatch = require('anymatch');
var matchers = [
'path/to/file.js',
'path/anyjs/**/*.js',
/foo\.js$/,
function (string) {
return string.indexOf('bar') !== -1 && string.length > 10
}
];
anymatch(matchers, 'path/to/file.js'); // true
anymatch(matchers, 'path/anyjs/baz.js'); // true
anymatch(matchers, 'path/to/foo.js'); // true
anymatch(matchers, 'path/to/bar.js'); // true
anymatch(matchers, 'bar.js'); // false
// returnIndex = true
anymatch(matchers, 'foo.js', true); // 2
anymatch(matchers, 'path/anyjs/foo.js', true); // 1
// skip matchers
anymatch(matchers, 'path/to/file.js', false, 1); // false
anymatch(matchers, 'path/anyjs/foo.js', true, 2, 3); // 2
anymatch(matchers, 'path/to/bar.js', true, 0, 3); // -1
// using globs to match directories and their children
anymatch('node_modules', 'node_modules'); // true
anymatch('node_modules', 'node_modules/somelib/index.js'); // false
anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
```
#### anymatch (matchers)
You can also pass in only your matcher(s) to get a curried function that has
already been bound to the provided matching criteria. This can be used as an
`Array.prototype.filter` callback.
```js
var matcher = anymatch(matchers);
matcher('path/to/file.js'); // true
matcher('path/anyjs/baz.js', true); // 1
matcher('path/anyjs/baz.js', true, 2); // -1
['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
```
Change Log
----------
[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
NOTE: As of v2.0.0, [micromatch](https://github.com/jonschlinkert/micromatch) moves away from minimatch-parity and inline with Bash. This includes handling backslashes differently (see https://github.com/micromatch/micromatch#backslashes for more information).
NOTE: As of v1.2.0, anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
for glob pattern matching. Issues with glob pattern matching should be
reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

> Normalize file path slashes to be unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes unless disabled.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save normalize-path
```
## Usage
```js
var normalize = require('normalize-path');
normalize('\\foo\\bar\\baz\\');
//=> '/foo/bar/baz'
normalize('./foo/bar/baz/');
//=> './foo/bar/baz'
```
Pass `false` as the last argument to **keep** trailing slashes:
```js
normalize('./foo/bar/baz/', false);
//=> './foo/bar/baz/'
normalize('foo\\bar\\baz\\', false);
//=> 'foo/bar/baz/'
```

> 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
```
## Why use braces?
Brace patterns are great for matching ranges. Users (and implementors) shouldn't have to think about whether or not they will break their application (or yours) from accidentally defining an aggressive brace pattern. _Braces is the only library that offers a [solution to this problem](#performance)_.
* **Safe(r)**: Braces isn't vulnerable to DoS attacks like [brace-expansion](https://github.com/juliangruber/brace-expansion), [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch) (a different bug than the [other regex DoS bug](https://medium.com/node-security/minimatch-redos-vulnerability-590da24e6d3c#.jew0b6mpc)).
* **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**: with parser and compiler that are eas(y|ier) to maintain and update when edge cases crop up.
* **Well-tested**: thousands of test assertions. Passes 100% of the [minimatch](https://github.com/isaacs/minimatch) and [brace-expansion](https://github.com/juliangruber/brace-expansion) unit tests as well (as of the writing of this).
## Usage
The main export is a function that takes one or more brace `patterns` and `options`.
```js
var braces = require('braces');
braces(pattern[, options]);
```
By default, braces returns an optimized regex-source string. To get an array of brace patterns, use `brace.expand()`.
The following section explains the difference in more detail. _(If you're curious about "why" braces does this by default, see [brace matching pitfalls](#brace-matching-pitfalls)_.
### Optimized vs. expanded braces
**Optimized**
By default, patterns are optimized for regex and matching:
```js
console.log(braces('a/{x,y,z}/b'));
//=> ['a/(x|y|z)/b']
```
**Expanded**
To expand patterns the same way as Bash or [minimatch](https://github.com/isaacs/minimatch), use the [.expand](#expand) method:
```js
console.log(braces.expand('a/{x,y,z}/b'));
//=> ['a/x/b', 'a/y/b', 'a/z/b']
```
Or use [options.expand](#optionsexpand):
```js
console.log(braces('a/{x,y,z}/b', {expand: true}));
//=> ['a/x/b', 'a/y/b', 'a/z/b']
```
## Features
* [lists](#lists): Supports "lists": `a/{b,c}/d` => `['a/b/d', 'a/c/d']`
* [sequences](#sequences): Supports alphabetical or numerical "sequences" (ranges): `{1..3}` => `['1', '2', '3']`
* [steps](#steps): Supports "steps" or increments: `{2..10..2}` => `['2', '4', '6', '8', '10']`
* [escaping](#escaping)
* [options](#options)
### Lists
Uses [fill-range](https://github.com/jonschlinkert/fill-range) for expanding alphabetical or numeric lists:
```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
Uses [fill-range](https://github.com/jonschlinkert/fill-range) for expanding alphabetical or numeric ranges (bash "sequences"):
```js
console.log(braces.expand('{1..3}')); // ['1', '2', '3']
console.log(braces.expand('a{01..03}b')); // ['a01b', 'a02b', 'a03b']
console.log(braces.expand('a{1..3}b')); // ['a1b', 'a2b', 'a3b']
console.log(braces.expand('{a..c}')); // ['a', 'b', 'c']
console.log(braces.expand('foo/{a..c}')); // ['foo/a', 'foo/b', 'foo/c']
// supports 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' ]
```
### Steps
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 (this option is unncessary with the `.expand` method, which does the same thing).
```js
console.log(braces('a/{b,c}/d', {expand: true}));
//=> [ 'a/b/d', 'a/c/d' ]
```
### options.optimize
**Type**: `Boolean`
**Default**: `true`
**Description**: Enabled by default.
```js
console.log(braces('a/{b,c}/d'));
//=> [ 'a/(b|c)/d' ]
```
### options.nodupes
**Type**: `Boolean`
**Default**: `true`
**Description**: Duplicates are removed by default. To keep duplicates, pass `{nodupes: false}` on the options
### options.rangeLimit
**Type**: `Number`
**Default**: `250`
**Description**: When `braces.expand()` is used, or `options.expand` is true, brace patterns will automatically be [optimized](#optionsoptimize) when the difference between the range minimum and range maximum exceeds the `rangeLimit`. This is to prevent huge ranges from freezing your application.
You can set this to any number, or change `options.rangeLimit` 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.
```js
var range = braces.expand('x{a..e}y', {
transform: function(str) {
return 'foo' + str;
}
});
console.log(range);
//=> [ 'xfooay', 'xfooby', 'xfoocy', 'xfoody', 'xfooey' ]
```
### 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
var 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](https://github.com/isaacs/minimatch)** |

| `{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)_

| `{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) |

> A neat wrapper around node.js fs.watch / fs.watchFile / FSEvents.
[![NPM](https://nodei.co/npm/chokidar.png)](https://www.npmjs.com/package/chokidar)
## Why?
Node.js `fs.watch`:
* Doesn't report filenames on MacOS.
* Doesn't report events at all when using editors like Sublime on MacOS.
* Often reports events twice.
* Emits most changes as `rename`.
* Has [a lot of other issues](https://github.com/nodejs/node/search?q=fs.watch&type=Issues)
* Does not provide an easy way to recursively watch file trees.
Node.js `fs.watchFile`:
* Almost as bad at event handling.
* Also does not provide any recursive watching.
* Results in high CPU utilization.
Chokidar resolves these problems.
Initially made for **[Brunch](http://brunch.io)** (an ultra-swift web app build tool), it is now used in
[gulp](https://github.com/gulpjs/gulp/),
[karma](http://karma-runner.github.io),
[PM2](https://github.com/Unitech/PM2),
[browserify](http://browserify.org/),
[webpack](http://webpack.github.io/),
[BrowserSync](http://www.browsersync.io/),
[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
and [many others](https://www.npmjs.org/browse/depended/chokidar/).
It has proven itself in production environments.
## How?
Chokidar does still rely on the Node.js core `fs` module, but when using
`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
receives, often checking for truth by getting file stats and/or dir contents.
On MacOS, chokidar by default uses a native extension exposing the Darwin
`FSEvents` API. This provides very efficient recursive watching compared with
implementations like `kqueue` available on most \*nix platforms. Chokidar still
does have to do some work to normalize the events received that way as well.
On other platforms, the `fs.watch`-based implementation is the default, which
avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
watchers recursively for everything within scope of the paths that have been
specified, so be judicious about not wasting system resources by watching much
more than needed.
## Getting started
Install with npm:
```sh
npm install chokidar
```
Then `require` and use it in your code:
```javascript
var chokidar = require('chokidar');
// One-liner for current directory, ignores .dotfiles
chokidar.watch('.', {ignored: /(^|[\/\\])\../}).on('all', (event, path) => {
console.log(event, path);
});
```
```javascript
// Example of a more typical implementation structure:
// Initialize watcher.
var watcher = chokidar.watch('file, dir, glob, or array', {
ignored: /(^|[\/\\])\../,
persistent: true
});
// Something to use when events are received.
var log = console.log.bind(console);
// Add event listeners.
watcher
.on('add', path => log(`File ${path} has been added`))
.on('change', path => log(`File ${path} has been changed`))
.on('unlink', path => log(`File ${path} has been removed`));
// More possible events.
watcher
.on('addDir', path => log(`Directory ${path} has been added`))
.on('unlinkDir', path => log(`Directory ${path} has been removed`))
.on('error', error => log(`Watcher error: ${error}`))
.on('ready', () => log('Initial scan complete. Ready for changes'))
.on('raw', (event, path, details) => {
log('Raw event info:', event, path, details);
});
// 'add', 'addDir' and 'change' events also receive stat() results as second
// argument when available: http://nodejs.org/api/fs.html#fs_class_fs_stats
watcher.on('change', (path, stats) => {
if (stats) console.log(`File ${path} changed size to ${stats.size}`);
});
// Watch new files.
watcher.add('new-file');
watcher.add(['new-file-2', 'new-file-3', '**/other-file*']);
// Get list of actual paths being watched on the filesystem
var watchedPaths = watcher.getWatched();
// Un-watch some files.
watcher.unwatch('new-file*');
// Stop watching.
watcher.close();
// Full list of options. See below for descriptions. (do not use this example)
chokidar.watch('file', {
persistent: true,
ignored: '*.txt',
ignoreInitial: false,
followSymlinks: true,
cwd: '.',
disableGlobbing: false,
usePolling: true,
interval: 100,
binaryInterval: 300,
alwaysStat: false,
depth: 99,
awaitWriteFinish: {
stabilityThreshold: 2000,
pollInterval: 100
},
ignorePermissionErrors: false,
atomic: true // or a custom 'atomicity delay', in milliseconds (default 100)
});
```
## API
`chokidar.watch(paths, [options])`
* `paths` (string or array of strings). Paths to files, dirs to be watched
recursively, or glob patterns.
* `options` (object) Options object as defined below:
#### Persistence
* `persistent` (default: `true`). Indicates whether the process
should continue to run as long as files are being watched. If set to
`false` when using `fsevents` to watch, no more events will be emitted
after `ready`, even if the process continues to run.
#### Path filtering
* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition)
Defines files/paths to be ignored. The whole relative or absolute path is
tested, not just filename. If a function with two arguments is provided, it
gets called twice per path - once with a single argument (the path), second
time with two arguments (the path and the
[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats)
object of that path).
* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
instantiating the watching as chokidar discovers these file paths (before the `ready` event).
* `followSymlinks` (default: `true`). When `false`, only the
symlinks themselves will be watched for changes instead of following
the link references and bubbling events through the link's path.
* `cwd` (no default). The base directory from which watch `paths` are to be
derived. Paths emitted with events will be relative to this.
* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as
literal path names, even if they look like globs.
#### Performance
* `usePolling` (default: `false`).
Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
leads to high CPU utilization, consider setting this to `false`. It is
typically necessary to **set this to `true` to successfully watch files over
a network**, and it may be necessary to successfully watch files in other
non-standard situations. Setting to `true` explicitly on MacOS overrides the
`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
to true (1) or false (0) in order to override this option.
* _Polling-specific settings_ (effective when `usePolling: true`)
* `interval` (default: `100`). Interval of file system polling. You may also
set the CHOKIDAR_INTERVAL env variable to override this option.
* `binaryInterval` (default: `300`). Interval of file system
polling for binary files.
([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
* `useFsEvents` (default: `true` on MacOS). Whether to use the
`fsevents` watching interface if available. When set to `true` explicitly
and `fsevents` is available this supercedes the `usePolling` setting. When
set to `false` on MacOS, `usePolling: true` becomes the default.
* `alwaysStat` (default: `false`). If relying upon the
[`fs.Stats`](http://nodejs.org/api/fs.html#fs_class_fs_stats)
object that may get passed with `add`, `addDir`, and `change` events, set
this to `true` to ensure it is provided even in cases where it wasn't
already available from the underlying watch events.
* `depth` (default: `undefined`). If set, limits how many levels of
subdirectories will be traversed.
* `awaitWriteFinish` (default: `false`).
By default, the `add` event will fire when a file first appears on disk, before
the entire file has been written. Furthermore, in some cases some `change`
events will be emitted while the file is being written. In some cases,
especially when watching for large files there will be a need to wait for the
write operation to finish before responding to a file creation or modification.
Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
holding its `add` and `change` events until the size does not change for a
configurable amount of time. The appropriate duration setting is heavily
dependent on the OS and hardware. For accurate detection this parameter should
be relatively high, making file watching much less responsive.
Use with caution.
* *`options.awaitWriteFinish` can be set to an object in order to adjust
timing params:*
* `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
milliseconds for a file size to remain constant before emitting its event.
* `awaitWriteFinish.pollInterval` (default: 100). File size polling interval.
#### Errors
* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
that don't have read permissions if possible. If watching fails due to `EPERM`
or `EACCES` with this set to `true`, the errors will be suppressed silently.
* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
Automatically filters out artifacts that occur when using editors that use
"atomic writes" instead of writing directly to the source file. If a file is
re-added within 100 ms of being deleted, Chokidar emits a `change` event
rather than `unlink` then `add`. If the default of 100 ms does not work well
for you, you can override it by setting `atomic` to a custom value, in
milliseconds.
### Methods & Events
`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
* `.add(path / paths)`: Add files, directories, or glob patterns for tracking.
Takes an array of strings or just one string.
* `.on(event, callback)`: Listen for an FS event.
Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
`raw`, `error`.
Additionally `all` is available which gets emitted with the underlying event
name and path for every event other than `ready`, `raw`, and `error`.
* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
Takes an array of strings or just one string.
* `.close()`: Removes all listeners from watched files.
* `.getWatched()`: Returns an object representing all the paths on the file
system being watched by this `FSWatcher` instance. The object's keys are all the
directories (using absolute paths unless the `cwd` option was used), and the
values are arrays of the names of the items contained in each directory.
## CLI
If you need a CLI interface for your file watching, check out
[chokidar-cli](https://github.com/kimmobrunfeldt/chokidar-cli), allowing you to
execute a command on each change, or get a stdio stream of change events.
## Install Troubleshooting
* `npm WARN optional dep failed, continuing fsevents@n.n.n`
* This message is normal part of how `npm` handles optional dependencies and is
not indicative of a problem. Even if accompanied by other related error messages,
Chokidar should function properly.
* `ERR! stack Error: Python executable "python" is v3.4.1, which is not supported by gyp.`
* You should be able to resolve this by installing python 2.7 and running:
`npm config set python python2.7`
* `gyp ERR! stack Error: not found: make`
* On Mac, install the XCode command-line tools

# cliui
[![Build Status](https://travis-ci.org/yargs/cliui.svg)](https://travis-ci.org/yargs/cliui)
[![Coverage Status](https://coveralls.io/repos/yargs/cliui/badge.svg?branch=)](https://coveralls.io/r/yargs/cliui?branch=)
[![NPM version](https://img.shields.io/npm/v/cliui.svg)](https://www.npmjs.com/package/cliui)
[![Standard Version](https://img.shields.io/badge/release-standard%20version-brightgreen.svg)](https://github.com/conventional-changelog/standard-version)
easily create complex multi-column command-line-interfaces.
## Example
```js
var ui = require('cliui')()
ui.div('Usage: $0 [command] [options]')
ui.div({
text: 'Options:',
padding: [2, 0, 2, 0]
})
ui.div(
{
text: "-f, --file",
width: 20,
padding: [0, 4, 0, 4]
},
{
text: "the file to load." +
chalk.green("(if this description is long it wraps).")
,
width: 20
},
{
text: chalk.red("[required]"),
align: 'right'
}
)
console.log(ui.toString())
```
<img width="500" src="screenshot.png">
## Layout DSL
cliui exposes a simple layout DSL:
If you create a single `ui.div`, passing a string rather than an
object:
* `\n`: characters will be interpreted as new rows.
* `\t`: characters will be interpreted as new columns.
* `\s`: characters will be interpreted as padding.
**as an example...**
```js
var ui = require('./')({
width: 60
})
ui.div(
'Usage: node ./bin/foo.js\n' +
' <regex>\t provide a regex\n' +
' <glob>\t provide a glob\t [required]'
)
console.log(ui.toString())
```
**will output:**
```shell
Usage: node ./bin/foo.js
<regex> provide a regex
<glob> provide a glob [required]
```
## Methods
```js
cliui = require('cliui')
```
### cliui({width: integer})
Specify the maximum width of the UI being generated.
If no width is provided, cliui will try to get the current window's width and use it, and if that doesn't work, width will be set to `80`.
### cliui({wrap: boolean})
Enable or disable the wrapping of text in a column.
### cliui.div(column, column, column)
Create a row with any number of columns, a column
can either be a string, or an object with the following
options:
* **text:** some text to place in the column.
* **width:** the width of a column.
* **align:** alignment, `right` or `center`.
* **padding:** `[top, right, bottom, left]`.
* **border:** should a border be placed around the div?
### cliui.span(column, column, column)
Similar to `div`, except the next row will be appended without
a new line being created.
### cliui.resetOutput()
Resets the UI elements of the current cliui instance, maintaining the values
set for `width` and `wrap`.
