# Chokidar [![Weekly downloads](https://img.shields.io/npm/dw/chokidar.svg)](https://github.com/paulmillr/chokidar) [![Yearly downloads](https://img.shields.io/npm/dy/chokidar.svg)](https://github.com/paulmillr/chokidar)
> Minimal and efficient cross-platform file watching library
[![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`.
* Does not provide an easy way to recursively watch file trees.
* Does not support recursive watching on Linux.
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](https://brunch.io/)** (an ultra-swift web app build tool), it is now used in
[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
[gulp](https://github.com/gulpjs/gulp/),
[karma](https://karma-runner.github.io/),
[PM2](https://github.com/Unitech/PM2),
[browserify](http://browserify.org/),
[webpack](https://webpack.github.io/),
[BrowserSync](https://www.browsersync.io/),
and [many others](https://www.npmjs.com/browse/depended/chokidar).
It has proven itself in production environments.
Version 3 is out! Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/)
## 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 most 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
const chokidar = require('chokidar');
// One-liner for current directory
chokidar.watch('.').on('all', (event, path) => {
console.log(event, path);
});
```
## API
```javascript
// Example of a more typical implementation structure
// Initialize watcher.
const watcher = chokidar.watch('file, dir, glob, or array', {
ignored: /(^|[\/\\])\../, // ignore dotfiles
persistent: true
});
// Something to use when events are received.
const 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) => { // internal
log('Raw event info:', event, path, details);
});
// 'add', 'addDir' and 'change' events also receive stat() results as second
// argument when available: https://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.
await watcher.unwatch('new-file*');
// Stop watching.
// The method is async!
watcher.close().then(() => console.log('closed'));
// 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: false,
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)
});
```
`chokidar.watch(paths, [options])`
* `paths` (string or array of strings). Paths to files, dirs to be watched
recursively, or glob patterns.
- Note: globs must not contain windows separators (`\`),
because that's how they work by the standard —
you'll need to replace them with forward slashes (`/`).
- Note 2: for additional glob documentation, check out low-level
library: [picomatch](https://github.com/micromatch/picomatch).
* `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`](https://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, in milliseconds. 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`](https://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, in milliseconds.
#### 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`. `raw` is internal, use it carefully.
* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
Takes an array of strings or just one string.
* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen.
* `.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/open-cli-tools/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.
* `TypeError: fsevents is not a constructor`
* Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar.
* Chokidar is producing `ENOSP` error on Linux, like this:
* `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell`
`Error: watch /home/ ENOSPC`
* This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal:
`echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`

## Also
Why was chokidar named this way? What's the meaning behind it?
>Chowkidar is a transliteration of a Hindi word meaning 'watchman, gatekeeper', चौकीदार. This ultimately comes from Sanskrit _ चतुष्क_ (crossway, quadrangle, consisting-of-four). This word is also used in other languages like Urdu as (چوکیدار) which is widely used in Pakistan and India.

# glob-parent
[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Azure Pipelines Build Status][azure-pipelines-image]][azure-pipelines-url] [![Travis Build Status][travis-image]][travis-url] [![AppVeyor Build Status][appveyor-image]][appveyor-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Gitter chat][gitter-image]][gitter-url]
Extract the non-magic parent path from a glob string.
## Usage
```js
var globParent = require('glob-parent');
globParent('path/to/*.js'); // 'path/to'
globParent('/root/path/to/*.js'); // '/root/path/to'
globParent('/*.js'); // '/'
globParent('*.js'); // '.'
globParent('**/*.js'); // '.'
globParent('path/{to,from}'); // 'path'
globParent('path/!(to|from)'); // 'path'
globParent('path/?(to|from)'); // 'path'
globParent('path/+(to|from)'); // 'path'
globParent('path/*(to|from)'); // 'path'
globParent('path/@(to|from)'); // 'path'
globParent('path/**/*'); // 'path'
// if provided a non-glob path, returns the nearest dir
globParent('path/foo/bar.js'); // 'path/foo'
globParent('path/foo/'); // 'path/foo'
globParent('path/foo'); // 'path' (see issue #3 for details)
```
## API
### `globParent(maybeGlobString, [options])`
Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.
#### options
```js
{
// Disables the automatic conversion of slashes for Windows
flipBackslashes: true
}
```
## Escaping
The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
- `?` (question mark) unless used as a path segment alone
- `*` (asterisk)
- `|` (pipe)
- `(` (opening parenthesis)
- `)` (closing parenthesis)
- `{` (opening curly brace)
- `}` (closing curly brace)
- `[` (opening bracket)
- `]` (closing bracket)
**Example**
```js
globParent('foo/[bar]/') // 'foo'
globParent('foo/\\[bar]/') // 'foo/[bar]'
```
## Limitations
### Braces & Brackets
This library attempts a quick and imperfect method of determining which path
parts have glob magic without fully parsing/lexing the pattern. There are some
advanced use cases that can trip it up, such as nested braces where the outer
pair is escaped and the inner one contains a path separator. If you find
yourself in the unlikely circumstance of being affected by this or need to
ensure higher-fidelity glob handling in your library, it is recommended that you
pre-process your input with [expand-braces] and/or [expand-brackets].
### Windows
Backslashes are not valid path separators for globs. If a path with backslashes
is provided anyway, for simple cases, glob-parent will replace the path
separator for you and return the non-glob parent path (now with
forward-slashes, which are still valid as Windows path separators).
This cannot be used in conjunction with escape characters.
```js
// BAD
globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)'
// GOOD
globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)'
```
If you are using escape characters for a pattern without path parts (i.e.
relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
```js
// BAD
globParent('foo \\[bar]') // 'foo '
globParent('foo \\[bar]*') // 'foo '
// GOOD
globParent('./foo \\[bar]') // 'foo [bar]'
globParent('./foo \\[bar]*') // '.'
```

# glob-parent
[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][ci-image]][ci-url] [![Coveralls Status][coveralls-image]][coveralls-url]
Extract the non-magic parent path from a glob string.
## Usage
```js
var globParent = require('glob-parent');
globParent('path/to/*.js'); // 'path/to'
globParent('/root/path/to/*.js'); // '/root/path/to'
globParent('/*.js'); // '/'
globParent('*.js'); // '.'
globParent('**/*.js'); // '.'
globParent('path/{to,from}'); // 'path'
globParent('path/!(to|from)'); // 'path'
globParent('path/?(to|from)'); // 'path'
globParent('path/+(to|from)'); // 'path'
globParent('path/*(to|from)'); // 'path'
globParent('path/@(to|from)'); // 'path'
globParent('path/**/*'); // 'path'
// if provided a non-glob path, returns the nearest dir
globParent('path/foo/bar.js'); // 'path/foo'
globParent('path/foo/'); // 'path/foo'
globParent('path/foo'); // 'path' (see issue #3 for details)
```
## API
### `globParent(maybeGlobString, [options])`
Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.
#### options
```js
{
// Disables the automatic conversion of slashes for Windows
flipBackslashes: true;
}
```
## Escaping
The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
- `?` (question mark) unless used as a path segment alone
- `*` (asterisk)
- `|` (pipe)
- `(` (opening parenthesis)
- `)` (closing parenthesis)
- `{` (opening curly brace)
- `}` (closing curly brace)
- `[` (opening bracket)
- `]` (closing bracket)
**Example**
```js
globParent('foo/[bar]/'); // 'foo'
globParent('foo/\\[bar]/'); // 'foo/[bar]'
```
## Limitations
### Braces & Brackets
This library attempts a quick and imperfect method of determining which path
parts have glob magic without fully parsing/lexing the pattern. There are some
advanced use cases that can trip it up, such as nested braces where the outer
pair is escaped and the inner one contains a path separator. If you find
yourself in the unlikely circumstance of being affected by this or need to
ensure higher-fidelity glob handling in your library, it is recommended that you
pre-process your input with [expand-braces] and/or [expand-brackets].
### Windows
Backslashes are not valid path separators for globs. If a path with backslashes
is provided anyway, for simple cases, glob-parent will replace the path
separator for you and return the non-glob parent path (now with
forward-slashes, which are still valid as Windows path separators).
This cannot be used in conjunction with escape characters.
```js
// BAD
globParent('C:\\Program Files \\(x86\\)\\*.ext'); // 'C:/Program Files /(x86/)'
// GOOD
globParent('C:/Program Files\\(x86\\)/*.ext'); // 'C:/Program Files (x86)'
```
If you are using escape characters for a pattern without path parts (i.e.
relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
```js
// BAD
globParent('foo \\[bar]'); // 'foo '
globParent('foo \\[bar]*'); // 'foo '
// GOOD
globParent('./foo \\[bar]'); // 'foo [bar]'
globParent('./foo \\[bar]*'); // '.'
```

<strong>Blazing fast and accurate glob matcher written in JavaScript.</strong></br>
<em>No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.</em>
</p>
<br>
<br>
## Why picomatch?
* **Lightweight** - No dependencies
* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
* **Well tested** - Thousands of unit tests

## Install
Install with [npm](https://www.npmjs.com/):
```sh
npm install --save picomatch
```
<br>
## Usage
The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
```js
const pm = require('picomatch');
const isMatch = pm('*.js');
console.log(isMatch('abcd')); //=> false
console.log(isMatch('a.js')); //=> true
console.log(isMatch('a.md')); //=> false
console.log(isMatch('a/b.js')); //=> false
```
<br>
## API
### [picomatch](lib/picomatch.js#L32)
Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match. The returned matcher function also takes a boolean as the second argument that, when true, returns an object with additional information.
**Params**
* `globs` **{String|Array}**: One or more glob patterns.
* `options` **{Object=}**
* `returns` **{Function=}**: Returns a matcher function.
**Example**
```js
const picomatch = require('picomatch');
// picomatch(glob[, options]);
const isMatch = picomatch('*.!(*a)');
console.log(isMatch('a.a')); //=> false
console.log(isMatch('a.b')); //=> true
```
### [.test](lib/picomatch.js#L117)
Test `input` with the given `regex`. This is used by the main `picomatch()` function to test the input string.
**Params**
* `input` **{String}**: String to test.
* `regex` **{RegExp}**
* `returns` **{Object}**: Returns an object with matching info.
**Example**
```js
const picomatch = require('picomatch');
// picomatch.test(input, regex[, options]);
console.log(picomatch.test('foo/bar', /^(?:([^/]*?)\/([^/]*?))$/));
// { isMatch: true, match: [ 'foo/', 'foo', 'bar' ], output: 'foo/bar' }
```
### [.matchBase](lib/picomatch.js#L161)
Match the basename of a filepath.
**Params**
* `input` **{String}**: String to test.
* `glob` **{RegExp|String}**: Glob pattern or regex created by [.makeRe](#makeRe).
* `returns` **{Boolean}**
**Example**
```js
const picomatch = require('picomatch');
// picomatch.matchBase(input, glob[, options]);
console.log(picomatch.matchBase('foo/bar.js', '*.js'); // true
```
### [.isMatch](lib/picomatch.js#L183)
Returns true if **any** of the given glob `patterns` match the specified `string`.
**Params**
* **{String|Array}**: str The string to test.
* **{String|Array}**: patterns One or more glob patterns to use for matching.
* **{Object}**: See available [options](#options).
* `returns` **{Boolean}**: Returns true if any patterns match `str`
**Example**
```js
const picomatch = require('picomatch');
// picomatch.isMatch(string, patterns[, options]);
console.log(picomatch.isMatch('a.a', ['b.*', '*.a'])); //=> true
console.log(picomatch.isMatch('a.a', 'b.*')); //=> false
```
### [.parse](lib/picomatch.js#L199)
Parse a glob pattern to create the source string for a regular expression.
**Params**
* `pattern` **{String}**
* `options` **{Object}**
* `returns` **{Object}**: Returns an object with useful properties and output to be used as a regex source string.
**Example**
```js
const picomatch = require('picomatch');
const result = picomatch.parse(pattern[, options]);
```
### [.scan](lib/picomatch.js#L231)
Scan a glob pattern to separate the pattern into segments.
**Params**
* `input` **{String}**: Glob pattern to scan.
* `options` **{Object}**
* `returns` **{Object}**: Returns an object with
**Example**
```js
const picomatch = require('picomatch');
// picomatch.scan(input[, options]);
const result = picomatch.scan('!./foo/*.js');
console.log(result);
{ prefix: '!./',
input: '!./foo/*.js',
start: 3,
base: 'foo',
glob: '*.js',
isBrace: false,
isBracket: false,
isGlob: true,
isExtglob: false,
isGlobstar: false,
negated: true }
```
### [.compileRe](lib/picomatch.js#L245)
Compile a regular expression from the `state` object returned by the
[parse()](#parse) method.
**Params**
* `state` **{Object}**
* `options` **{Object}**
* `returnOutput` **{Boolean}**: Intended for implementors, this argument allows you to return the raw output from the parser.
* `returnState` **{Boolean}**: Adds the state to a `state` property on the returned regex. Useful for implementors and debugging.
* `returns` **{RegExp}**
### [.makeRe](lib/picomatch.js#L286)
Create a regular expression from a parsed glob pattern.
**Params**
* `state` **{String}**: The object returned from the `.parse` method.
* `options` **{Object}**
* `returnOutput` **{Boolean}**: Implementors may use this argument to return the compiled output, instead of a regular expression. This is not exposed on the options to prevent end-users from mutating the result.
* `returnState` **{Boolean}**: Implementors may use this argument to return the state from the parsed glob with the returned regular expression.
* `returns` **{RegExp}**: Returns a regex created from the given pattern.
**Example**
```js
const picomatch = require('picomatch');
const state = picomatch.parse('*.js');
// picomatch.compileRe(state[, options]);
console.log(picomatch.compileRe(state));
//=> /^(?:(?!\.)(?=.)[^/]*?\.js)$/
```
### [.toRegex](lib/picomatch.js#L321)
Create a regular expression from the given regex source string.
**Params**
* `source` **{String}**: Regular expression source string.
* `options` **{Object}**
* `returns` **{RegExp}**
**Example**
```js
const picomatch = require('picomatch');

const { output } = picomatch.parse('*.js');
console.log(picomatch.toRegex(output));
//=> /^(?:(?!\.)(?=.)[^/]*?\.js)$/
```

## Options
### Picomatch options
The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API.
| **Option** | **Type** | **Default value** | **Description** |
| --- | --- | --- | --- |
| `basename` | `boolean` | `false` | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes. For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
| `bash` | `boolean` | `false` | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
| `capture` | `boolean` | `undefined` | Return regex matches in supporting methods. |
| `contains` | `boolean` | `undefined` | Allows glob to match any part of the given string(s). |
| `cwd` | `string` | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
| `debug` | `boolean` | `undefined` | Debug regular expressions when an error is thrown. |
| `dot` | `boolean` | `false` | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
| `expandRange` | `function` | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
| `failglob` | `boolean` | `false` | Throws an error if no matches are found. Based on the bash option of the same name. |
| `fastpaths` | `boolean` | `true` | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
| `flags` | `string` | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
| `ignore` | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
| `keepQuotes` | `boolean` | `false` | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes. |
| `literalBrackets` | `boolean` | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
| `matchBase` | `boolean` | `false` | Alias for `basename` |
| `maxLength` | `boolean` | `65536` | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
| `nobrace` | `boolean` | `false` | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
| `nobracket` | `boolean` | `undefined` | Disable matching with regex brackets. |
| `nocase` | `boolean` | `false` | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
| `nodupes` | `boolean` | `true` | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
| `noext` | `boolean` | `false` | Alias for `noextglob` |
| `noextglob` | `boolean` | `false` | Disable support for matching with extglobs (like `+(a\|b)`) |
| `noglobstar` | `boolean` | `false` | Disable support for matching nested directories with globstars (`**`) |
| `nonegate` | `boolean` | `false` | Disable support for negating with leading `!` |
| `noquantifiers` | `boolean` | `false` | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. |
| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. |
| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. |
| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. |
| `posix` | `boolean` | `false` | Support POSIX character classes ("posix brackets"). |
| `posixSlashes` | `boolean` | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself |
| `prepend` | `boolean` | `undefined` | String to prepend to the generated regex used for matching. |
| `regex` | `boolean` | `false` | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). |
| `strictBrackets` | `boolean` | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. |
| `strictSlashes` | `boolean` | `undefined` | When true, picomatch won't match trailing slashes with single stars. |
| `unescape` | `boolean` | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. |
| `unixify` | `boolean` | `undefined` | Alias for `posixSlashes`, for backwards compatibility. |
picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
### Scan Options
In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
| **Option** | **Type** | **Default value** | **Description** |
| --- | --- | --- | --- |
| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
**Example**
```js
const picomatch = require('picomatch');
const result = picomatch.scan('!./foo/*.js', { tokens: true });
console.log(result);
// {
// prefix: '!./',
// input: '!./foo/*.js',
// start: 3,
// base: 'foo',
// glob: '*.js',
// isBrace: false,
// isBracket: false,
// isGlob: true,
// isExtglob: false,
// isGlobstar: false,
// negated: true,
// maxDepth: 2,
// tokens: [
// { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
// { value: 'foo', depth: 1, isGlob: false },
// { value: '*.js', depth: 1, isGlob: true }
// ],
// slashes: [ 2, 6 ],
// parts: [ 'foo', '*.js' ]
// }
```
<br>
### Options Examples
#### options.expandRange
**Type**: `function`
**Default**: `undefined`
Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
**Example**
The following example shows how to create a glob that matches a folder
```js
const fill = require('fill-range');
const regex = pm.makeRe('foo/{01..25}/bar', {
expandRange(a, b) {
return `(${fill(a, b, { toRegex: true })})`;
}
});
console.log(regex);
//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
console.log(regex.test('foo/00/bar')) // false
console.log(regex.test('foo/01/bar')) // true
console.log(regex.test('foo/10/bar')) // true
console.log(regex.test('foo/22/bar')) // true
console.log(regex.test('foo/25/bar')) // true
console.log(regex.test('foo/26/bar')) // false
```
#### options.format
**Type**: `function`
**Default**: `undefined`
Custom function for formatting strings before they're matched.
**Example**
```js
// strip leading './' from strings
const format = str => str.replace(/^\.\//, '');
const isMatch = picomatch('foo/*.js', { format });
console.log(isMatch('./foo/bar.js')); //=> true
```
#### options.onMatch
```js
const onMatch = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onMatch });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```
#### options.onIgnore
```js
const onIgnore = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```
#### options.onResult
```js
const onResult = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onResult, ignore: 'f*' });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```

## Globbing features
* [Basic globbing](#basic-globbing) (Wildcard matching)
* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
### Basic globbing
| **Character** | **Description** |
| --- | --- |
| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots. |
| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
#### Matching behavior vs. Bash
Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
<br>
### Advanced globbing
* [extglobs](#extglobs)
* [POSIX brackets](#posix-brackets)
* [Braces](#brace-expansion)
#### Extglobs
| **Pattern** | **Description** |
| --- | --- |
| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
| `!(pattern)` | Match _anything but_ `pattern` |
**Examples**
```js
const pm = require('picomatch');
// *(pattern) matches ZERO or more of "pattern"
console.log(pm.isMatch('a', 'a*(z)')); // true
console.log(pm.isMatch('az', 'a*(z)')); // true
console.log(pm.isMatch('azzz', 'a*(z)')); // true
// +(pattern) matches ONE or more of "pattern"
console.log(pm.isMatch('a', 'a*(z)')); // true
console.log(pm.isMatch('az', 'a*(z)')); // true
console.log(pm.isMatch('azzz', 'a*(z)')); // true
// supports multiple extglobs
console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
// supports nested extglobs
console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
```
#### POSIX brackets
POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
**Enable POSIX bracket support**
```js
console.log(pm.makeRe('[[:word:]]+', { posix: true }));
//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
```
**Supported POSIX classes**
The following named POSIX bracket expressions are supported:
* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
* `[:word:]` - Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
### Braces
Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
### Matching special characters as literals
If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
**Special Characters**
Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
To match any of the following characters as literals: `$^*+?()[]
Examples:
```js
console.log(pm.makeRe('foo/bar \\(1\\)'));
console.log(pm.makeRe('foo/bar \\(1\\)'));
```

## Philosophies
The goal of this library is to be blazing fast, without compromising on accuracy.
**Accuracy**
The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
**Performance**
Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

# API Documentation
*Please use only this documented API when working with the parser. Methods
not documented here are subject to change at any point.*
## `parser` function
This is the module's main entry point.
```js
const parser = require('postcss-selector-parser');
```
### `parser([transform], [options])`
Creates a new `processor` instance
```js
const processor = parser();
```
Or, with optional transform function
```js
const transform = selectors => {
selectors.walkUniversals(selector => {
selector.remove();
});
};
const processor = parser(transform)
// Example
const result = processor.processSync('*.class');
// => .class
```
[See processor documentation](#processor)
Arguments:
* `transform (function)`: Provide a function to work with the parsed AST.
* `options (object)`: Provide default options for all calls on the returned `Processor`.
### `parser.attribute([props])`
Creates a new attribute selector.
```js
parser.attribute({attribute: 'href'});
// => [href]
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.className([props])`
Creates a new class selector.
```js
parser.className({value: 'button'});
// => .button
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.combinator([props])`
Creates a new selector combinator.
```js
parser.combinator({value: '+'});
// => +
```
Arguments:
* `props (object)`: The new node's properties.
Notes:
* **Descendant Combinators** The value of descendant combinators created by the
parser always just a single space (`" "`). For descendant selectors with no
comments, additional space is now stored in `node.spaces.before`. Depending
on the location of comments, additional spaces may be stored in
`node.raws.spaces.before`, `node.raws.spaces.after`, or `node.raws.value`.
* **Named Combinators** Although, nonstandard and unlikely to ever become a standard,
named combinators like `/deep/` and `/for/` are parsed as combinators. The
`node.value` is name after being unescaped and normalized as lowercase. The
original value for the combinator name is stored in `node.raws.value`.
### `parser.comment([props])`
Creates a new comment.
```js
parser.comment({value: '/* Affirmative, Dave. I read you. */'});
// => /* Affirmative, Dave. I read you. */
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.id([props])`
Creates a new id selector.
```js
parser.id({value: 'search'});
// => #search
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.nesting([props])`
Creates a new nesting selector.
```js
parser.nesting();
// => &
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.pseudo([props])`
Creates a new pseudo selector.
```js
parser.pseudo({value: '::before'});
// => ::before
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.root([props])`
Creates a new root node.
```js
parser.root();
// => (empty)
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.selector([props])`
Creates a new selector node.
```js
parser.selector();
// => (empty)
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.string([props])`
Creates a new string node.
```js
parser.string();
// => (empty)
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.tag([props])`
Creates a new tag selector.
```js
parser.tag({value: 'button'});
// => button
```
Arguments:
* `props (object)`: The new node's properties.
### `parser.universal([props])`
Creates a new universal selector.
```js
parser.universal();
// => *
```
Arguments:
* `props (object)`: The new node's properties.
## Node types
### `node.type`
A string representation of the selector type. It can be one of the following;
`attribute`, `class`, `combinator`, `comment`, `id`, `nesting`, `pseudo`,
`root`, `selector`, `string`, `tag`, or `universal`. Note that for convenience,
these constants are exposed on the main `parser` as uppercased keys. So for
example you can get `id` by querying `parser.ID`.
```js
parser.attribute({attribute: 'href'}).type;
// => 'attribute'
```
### `node.parent`
Returns the parent node.
```js
root.nodes[0].parent === root;
```
### `node.toString()`, `String(node)`, or `'' + node`
Returns a string representation of the node.
```js
const id = parser.id({value: 'search'});
console.log(String(id));
// => #search
```
### `node.next()` & `node.prev()`
Returns the next/previous child of the parent node.
```js
const next = id.next();
if (next && next.type !== 'combinator') {
throw new Error('Qualified IDs are not allowed!');
}
```
### `node.replaceWith(node)`
Replace a node with another.
```js
const attr = selectors.first.first;
const className = parser.className({value: 'test'});
attr.replaceWith(className);
```
Arguments:
* `node`: The node to substitute the original with.
### `node.remove()`
Removes the node from its parent node.
```js
if (node.type === 'id') {
node.remove();
}
```
### `node.clone([opts])`
Returns a copy of a node, detached from any parent containers that the
original might have had.
```js
const cloned = node.clone();
```
### `node.isAtPosition(line, column)`
Return a `boolean` indicating whether this node includes the character at the
position of the given line and column. Returns `undefined` if the nodes lack
sufficient source metadata to determine the position.
Arguments:
* `line`: 1-index based line number relative to the start of the selector.
* `column`: 1-index based column number relative to the start of the selector.
### `node.spaces`
Extra whitespaces around the node will be moved into `node.spaces.before` and
`node.spaces.after`. So for example, these spaces will be moved as they have
no semantic meaning:
```css
h1 , h2 {}
```
For descendent selectors, the value is always a single space.
```css
h1 h2 {}
```
Additional whitespace is found in either the `node.spaces.before` and `node.spaces.after` depending on the presence of comments or other whitespace characters. If the actual whitespace does not start or end with a single space, the node's raw value is set to the actual space(s) found in the source.
### `node.source`
An object describing the node's start/end, line/column source position.
Within the following CSS, the `.bar` class node ...
```css
.foo,
.bar {}
```
... will contain the following `source` object.
```js
source: {
start: {
line: 2,
column: 3
},
end: {
line: 2,
column: 6
}
}
```
### `node.sourceIndex`
The zero-based index of the node within the original source string.
Within the following CSS, the `.baz` class node will have a `sourceIndex` of `12`.
```css
.foo, .bar, .baz {}
```
## Container types
The `root`, `selector`, and `pseudo` nodes have some helper methods for working
with their children.
### `container.nodes`
An array of the container's children.
```js
// Input: h1 h2
selectors.at(0).nodes.length // => 3
selectors.at(0).nodes[0].value // => 'h1'
selectors.at(0).nodes[1].value // => ' '
```
### `container.first` & `container.last`
The first/last child of the container.
```js
selector.first === selector.nodes[0];
selector.last === selector.nodes[selector.nodes.length - 1];
```
### `container.at(index)`
Returns the node at position `index`.
```js
selector.at(0) === selector.first;
selector.at(0) === selector.nodes[0];
```
Arguments:
* `index`: The index of the node to return.
### `container.atPosition(line, column)`
Returns the node at the source position `line` and `column`.
```js
// Input: :not(.foo),\n#foo > :matches(ol, ul)
selector.atPosition(1, 1); // => :not(.foo)
selector.atPosition(2, 1); // => \n#foo
```
Arguments:
* `line`: The line number of the node to return.
* `column`: The column number of the node to return.
### `container.index(node)`
Return the index of the node within its container.
```js
selector.index(selector.nodes[2]) // => 2
```
Arguments:
* `node`: A node within the current container.
### `container.length`
Proxy to the length of the container's nodes.
```js
container.length === container.nodes.length
```
### `container` Array iterators
The container class provides proxies to certain Array methods; these are:
* `container.map === container.nodes.map`
* `container.reduce === container.nodes.reduce`
* `container.every === container.nodes.every`
* `container.some === container.nodes.some`
* `container.filter === container.nodes.filter`
* `container.sort === container.nodes.sort`
Note that these methods only work on a container's immediate children; recursive
iteration is provided by `container.walk`.
### `container.each(callback)`
Iterate the container's immediate children, calling `callback` for each child.
You may return `false` within the callback to break the iteration.
```js
let className;
selectors.each((selector, index) => {
if (selector.type === 'class') {
className = selector.value;
return false;
}
});
```
Note that unlike `Array#forEach()`, this iterator is safe to use whilst adding
or removing nodes from the container.
Arguments:
* `callback (function)`: A function to call for each node, which receives `node`
and `index` arguments.
### `container.walk(callback)`
Like `container#each`, but will also iterate child nodes as long as they are
`container` types.
```js
selectors.walk((selector, index) => {
// all nodes
});
```
Arguments:
* `callback (function)`: A function to call for each node, which receives `node`
and `index` arguments.
This iterator is safe to use whilst mutating `container.nodes`,
like `container#each`.
### `container.walk` proxies
The container class provides proxy methods for iterating over types of nodes,
so that it is easier to write modules that target specific selectors. Those
methods are:
* `container.walkAttributes`
* `container.walkClasses`
* `container.walkCombinators`
* `container.walkComments`
* `container.walkIds`
* `container.walkNesting`
* `container.walkPseudos`
* `container.walkTags`
* `container.walkUniversals`
### `container.split(callback)`
This method allows you to split a group of nodes by returning `true` from
a callback. It returns an array of arrays, where each inner array corresponds
to the groups that you created via the callback.
```js
// (input) => h1 h2>>h3
const list = selectors.first.split(selector => {
return selector.type === 'combinator';
});
// (node values) => [['h1', ' '], ['h2', '>>'], ['h3']]
```
Arguments:
* `callback (function)`: A function to call for each node, which receives `node`
as an argument.
### `container.prepend(node)` & `container.append(node)`
Add a node to the start/end of the container. Note that doing so will set
the parent property of the node to this container.
```js
const id = parser.id({value: 'search'});
selector.append(id);
```
Arguments:
* `node`: The node to add.
### `container.insertBefore(old, new)` & `container.insertAfter(old, new)`
Add a node before or after an existing node in a container:
```js
selectors.walk(selector => {
if (selector.type !== 'class') {
const className = parser.className({value: 'theme-name'});
selector.parent.insertAfter(selector, className);
}
});
```
Arguments:
* `old`: The existing node in the container.
* `new`: The new node to add before/after the existing node.
### `container.removeChild(node)`
Remove the node from the container. Note that you can also use
`node.remove()` if you would like to remove just a single node.
```js
selector.length // => 2
selector.remove(id)
selector.length // => 1;
id.parent // undefined
```
Arguments:
* `node`: The node to remove.
### `container.removeAll()` or `container.empty()`
Remove all children from the container.
```js
selector.removeAll();
selector.length // => 0
```
## Root nodes
A root node represents a comma separated list of selectors. Indeed, all
a root's `toString()` method does is join its selector children with a ','.
Other than this, it has no special functionality and acts like a container.
### `root.trailingComma`
This will be set to `true` if the input has a trailing comma, in order to
support parsing of legacy CSS hacks.
## Selector nodes
A selector node represents a single complex selector. For example, this
selector string `h1 h2 h3, [href] > p`, is represented as two selector nodes.
It has no special functionality of its own.
## Pseudo nodes
A pseudo selector extends a container node; if it has any parameters of its
own (such as `h1:not(h2, h3)`), they will be its children. Note that the pseudo
`value` will always contain the colons preceding the pseudo identifier. This
is so that both `:before` and `::before` are properly represented in the AST.
## Attribute nodes
### `attribute.quoted`
Returns `true` if the attribute's value is wrapped in quotation marks, false if it is not.
Remains `undefined` if there is no attribute value.
```css
[href=foo] /* false */
[href='foo'] /* true */
[href="foo"] /* true */
[href] /* undefined */
```
### `attribute.qualifiedAttribute`
Returns the attribute name qualified with the namespace if one is given.
### `attribute.offsetOf(part)`
Returns the offset of the attribute part specified relative to the
start of the node of the output string. This is useful in raising
error messages about a specific part of the attribute, especially
in combination with `attribute.sourceIndex`.
Returns `-1` if the name is invalid or the value doesn't exist in this
attribute.
The legal values for `part` are:
* `"ns"` - alias for "namespace"
* `"namespace"` - the namespace if it exists.
* `"attribute"` - the attribute name
* `"attributeNS"` - the start of the attribute or its namespace
* `"operator"` - the match operator of the attribute
* `"value"` - The value (string or identifier)
* `"insensitive"` - the case insensitivity flag
### `attribute.raws.unquoted`
Returns the unquoted content of the attribute's value.
Remains `undefined` if there is no attribute value.
```css
[href=foo] /* foo */
[href='foo'] /* foo */
[href="foo"] /* foo */
[href] /* undefined */
```
### `attribute.spaces`
Like `node.spaces` with the `before` and `after` values containing the spaces
around the element, the parts of the attribute can also have spaces before
and after them. The for each of `attribute`, `operator`, `value` and
`insensitive` there is corresponding property of the same nam in
`node.spaces` that has an optional `before` or `after` string containing only
whitespace.
Note that corresponding values in `attributes.raws.spaces` contain values
including any comments. If set, these values will override the
`attribute.spaces` value. Take care to remove them if changing
`attribute.spaces`.
### `attribute.raws`
The raws object stores comments and other information necessary to re-render
the node exactly as it was in the source.
If a comment is embedded within the identifiers for the `namespace`, `attribute`
or `value` then a property is placed in the raws for that value containing the full source of the propery including comments.
If a comment is embedded within the space between parts of the attribute
then the raw for that space is set accordingly.
Setting an attribute's property `raws` value to be deleted.
For now, changing the spaces required also updating or removing any of the
raws values that override them.
Example: `[ /*before*/ href /* after-attr */ = /* after-operator */ te/*inside-value*/st/* wow */ /*omg*/i/*bbq*/ /*whodoesthis*/]` would parse as:
```js
{
attribute: "href",
operator: "=",
value: "test",
spaces: {
before: '',
after: '',
attribute: { before: ' ', after: ' ' },
operator: { after: ' ' },
value: { after: ' ' },
insensitive: { after: ' ' }
},
raws: {
spaces: {
attribute: { before: ' /*before*/ ', after: ' /* after-attr */ ' },
operator: { after: ' /* after-operator */ ' },
value: { after: '/* wow */ /*omg*/' },
insensitive: { after: '/*bbq*/ /*whodoesthis*/' }
},
unquoted: 'test',
value: 'te/*inside-value*/st'
}
}
```
## `Processor`
### `ProcessorOptions`
* `lossless` - When `true`, whitespace is preserved. Defaults to `true`.
* `updateSelector` - When `true`, if any processor methods are passed a postcss
`Rule` node instead of a string, then that Rule's selector is updated
with the results of the processing. Defaults to `true`.
### `process|processSync(selectors, [options])`
Processes the `selectors`, returning a string from the result of processing.
Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.
**Example:**
```js
const parser = require("postcss-selector-parser");
const processor = parser();
let result = processor.processSync(' .class');
console.log(result);
// => .class
// Asynchronous operation
let promise = processor.process(' .class').then(result => {
console.log(result)
// => .class
});
// To have the parser normalize whitespace values, utilize the options
result = processor.processSync(' .class ', {lossless: false});
console.log(result);
// => .class
// For better syntax errors, pass a PostCSS Rule node.
const postcss = require('postcss');
rule = postcss.rule({selector: ' #foo > a, .class '});
processor.process(rule, {lossless: false, updateSelector: true}).then(result => {
console.log(result);
// => #foo>a,.class
console.log("rule:", rule.selector);
// => rule: #foo>a,.class
})
```
Arguments:
* `selectors (string|postcss.Rule)`: Either a selector string or a PostCSS Rule
node.
* `[options] (object)`: Process options
### `ast|astSync(selectors, [options])`
Like `process()` and `processSync()` but after
processing the `selectors` these methods return the `Root` node of the result
instead of a string.
Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.
### `transform|transformSync(selectors, [options])`
Like `process()` and `processSync()` but after
processing the `selectors` these methods return the value returned by the
processor callback.
Note: when the `updateSelector` option is set, the rule's selector
will be updated with the resulting string.
### Error Handling Within Selector Processors
The root node passed to the selector processor callback
has a method `error(message, options)` that returns an
error object. This method should always be used to raise
errors relating to the syntax of selectors. The options
to this method are passed to postcss's error constructor
([documentation](http://postcss.org/api/#container-error)).
#### Async Error Example
```js
let processor = (root) => {
return new Promise((resolve, reject) => {
root.walkClasses((classNode) => {
if (/^(.*)[-_]/.test(classNode.value)) {
let msg = "classes may not have underscores or dashes in them";
reject(root.error(msg, {
index: classNode.sourceIndex + RegExp.$1.length + 1,
word: classNode.value
}));
}
});
resolve();
});
};
const postcss = require("postcss");
const parser = require("postcss-selector-parser");
const selectorProcessor = parser(processor);
const plugin = postcss.plugin('classValidator', (options) => {
return (root) => {
let promises = [];
root.walkRules(rule => {
promises.push(selectorProcessor.process(rule));
});
return Promise.all(promises);
};
});
postcss(plugin()).process(`
.foo-bar {
color: red;
}
`.trim(), {from: 'test.css'}).catch((e) => console.error(e.toString()));
// CssSyntaxError: classValidator: ./test.css:1:5: classes may not have underscores or dashes in them
//
// > 1 | .foo-bar {
// | ^
// 2 | color: red;
// 3 | }
```
#### Synchronous Error Example
```js
let processor = (root) => {
root.walkClasses((classNode) => {
if (/.*[-_]/.test(classNode.value)) {
let msg = "classes may not have underscores or dashes in them";
throw root.error(msg, {
index: classNode.sourceIndex,
word: classNode.value
});
}
});
};
const postcss = require("postcss");
const parser = require("postcss-selector-parser");
const selectorProcessor = parser(processor);
const plugin = postcss.plugin('classValidator', (options) => {
return (root) => {
root.walkRules(rule => {
selectorProcessor.processSync(rule);
});
};
});
postcss(plugin()).process(`
.foo-bar {
color: red;
}
`.trim(), {from: 'test.css'}).catch((e) => console.error(e.toString()));
// CssSyntaxError: classValidator: ./test.css:1:5: classes may not have underscores or dashes in them
//
// > 1 | .foo-bar {
// | ^
// 2 | color: red;
// 3 | }
```

# 5.0.0-rc.1
To ease adoption of the v5.0 release, we have relaxed the node version
check performed by npm at installation time to allow for node 4, which
remains officially unsupported, but likely to continue working for the
time being.
# 5.0.0-rc.0
This release has **BREAKING CHANGES** that were required to fix regressions
in 4.0.0 and to make the Combinator Node API consistent for all combinator
types. Please read carefully.
## Summary of Changes
* The way a descendent combinator that isn't a single space character (E.g. `.a .b`) is stored in the AST has changed.
* Named Combinators (E.g. `.a /for/ .b`) are now properly parsed as a combinator.
* It is now possible to look up a node based on the source location of a character in that node and to query nodes if they contain some character.
* Several bug fixes that caused the parser to hang and run out of memory when a `/` was encountered have been fixed.
* The minimum supported version of Node is now `v6.0.0`.
### Changes to the Descendent Combinator
In prior releases, the value of a descendant combinator with multiple spaces included all the spaces.
* `.a .b`: Extra spaces are now stored as space before.
- Old & Busted:
- `combinator.value === " "`
- New hotness:
- `combinator.value === " " && combinator.spaces.before === " "`
* `.a /*comment*/.b`: A comment at the end of the combinator causes extra space to become after space.
- Old & Busted:
- `combinator.value === " "`
- `combinator.raws.value === " /*comment/"`
- New hotness:
- `combinator.value === " "`
- `combinator.spaces.after === " "`
- `combinator.raws.spaces.after === " /*comment*/"`
* `.a<newline>.b`: whitespace that doesn't start or end with a single space character is stored as a raw value.
- Old & Busted:
- `combinator.value === "\n"`
- `combinator.raws.value === undefined`
- New hotness:
- `combinator.value === " "`
- `combinator.raws.value === "\n"`
### Support for "Named Combinators"
Although, nonstandard and unlikely to ever become a standard, combinators like `/deep/` and `/for/` are now properly supported.
Because they've been taken off the standardization track, there is no spec-official name for combinators of the form `/<ident>/`. However, I talked to [Tab Atkins](https://twitter.com/tabatkins) and we agreed to call them "named combinators" so now they are called that.
Before this release such named combinators were parsed without intention and generated three nodes of type `"tag"` where the first and last nodes had a value of `"/"`.
* `.a /for/ .b` is parsed as a combinator.
- Old & Busted:
- `root.nodes[0].nodes[1].type === "tag"`
- `root.nodes[0].nodes[1].value === "/"`
- New hotness:
- `root.nodes[0].nodes[1].type === "combinator"`
- `root.nodes[0].nodes[1].value === "/for/"`
* `.a /F\6fR/ .b` escapes are handled and uppercase is normalized.
- Old & Busted:
- `root.nodes[0].nodes[2].type === "tag"`
- `root.nodes[0].nodes[2].value === "F\\6fR"`
- New hotness:
- `root.nodes[0].nodes[1].type === "combinator"`
- `root.nodes[0].nodes[1].value === "/for/"`
- `root.nodes[0].nodes[1].raws.value === "/F\\6fR/"`
### Source position checks and lookups
A new API was added to look up a node based on the source location.
```js
const selectorParser = require("postcss-selector-parser");
// You can find the most specific node for any given character
let combinator = selectorParser.astSync(".a > .b").atPosition(1,4);
combinator.toString() === " > ";
// You can check if a node includes a specific character
// Whitespace surrounding the node that is owned by that node
// is included in the check.
[2,3,4,5,6].map(column => combinator.isAtPosition(1, column));
// => [false, true, true, true, false]
```
# 4.0.0
This release has **BREAKING CHANGES** that were required to fix bugs regarding values with escape sequences. Please read carefully.
* **Identifiers with escapes** - CSS escape sequences are now hidden from the public API by default.
The normal value of a node like a class name or ID, or an aspect of a node such as attribute
selector's value, is unescaped. Escapes representing Non-ascii characters are unescaped into
unicode characters. For example: `bu\tton, .\31 00, #i\2764\FE0Fu, [attr="value is \"quoted\""]`
will parse respectively to the values `button`, `100`, `i❤️u`, `value is "quoted"`.
The original escape sequences for these values can be found in the corresponding property name
in `node.raws`. Where possible, deprecation warnings were added, but the nature
of escape handling makes it impossible to detect what is escaped or not. Our expectation is
that most users are neither expecting nor handling escape sequences in their use of this library,
and so for them, this is a bug fix. Users who are taking care to handle escapes correctly can
now update their code to remove the escape handling and let us do it for them.
* **Mutating values with escapes** - When you make an update to a node property that has escape handling
The value is assumed to be unescaped, and any special characters are escaped automatically and
the corresponding `raws` value is immediately updated. This can result in changes to the original
escape format. Where the exact value of the escape sequence is important there are methods that
allow both values to be set in conjunction. There are a number of new convenience methods for
manipulating values that involve escapes, especially for attributes values where the quote mark
is involved. See https://github.com/postcss/postcss-selector-parser/pull/133 for an extensive
write-up on these changes.
**Upgrade/API Example**
In `3.x` there was no unescape handling and internal consistency of several properties was the caller's job to maintain. It was very easy for the developer
to create a CSS file that did not parse correctly when some types of values
were in use.
```js
const selectorParser = require("postcss-selector-parser");
let attr = selectorParser.attribute({attribute: "id", operator: "=", value: "a-value"});
attr.value; // => "a-value"
attr.toString(); // => [id=a-value]
// Add quotes to an attribute's value.
// All these values have to be set by the caller to be consistent:
// no internal consistency is maintained.
attr.raws.unquoted = attr.value
attr.value = "'" + attr.value + "'";
attr.value; // => "'a-value'"
attr.quoted = true;
attr.toString(); // => "[id='a-value']"
```
In `4.0` there is a convenient API for setting and mutating values
that may need escaping. Especially for attributes.
```js
const selectorParser = require("postcss-selector-parser");
// The constructor requires you specify the exact escape sequence
let className = selectorParser.className({value: "illegal class name", raws: {value: "illegal\\ class\\ name"}});
className.toString(); // => '.illegal\\ class\\ name'
// So it's better to set the value as a property
className = selectorParser.className();
// Most properties that deal with identifiers work like this
className.value = "escape for me";
className.value; // => 'escape for me'
className.toString(); // => '.escape\\ for\\ me'
// emoji and all non-ascii are escaped to ensure it works in every css file.
className.value = "😱🦄😍";
className.value; // => '😱🦄😍'
className.toString(); // => '.\\1F631\\1F984\\1F60D'
// you can control the escape sequence if you want, or do bad bad things
className.setPropertyAndEscape('value', 'xxxx', 'yyyy');
className.value; // => "xxxx"
className.toString(); // => ".yyyy"
// Pass a value directly through to the css output without escaping it.
className.setPropertyWithoutEscape('value', '$REPLACE_ME$');
className.value; // => "$REPLACE_ME$"
className.toString(); // => ".$REPLACE_ME$"
// The biggest changes are to the Attribute class
// passing quoteMark explicitly is required to avoid a deprecation warning.
let attr = selectorParser.attribute({attribute: "id", operator: "=", value: "a-value", quoteMark: null});
attr.toString(); // => "[id=a-value]"
// Get the value with quotes on it and any necessary escapes.
// This is the same as reading attr.value in 3.x.
attr.getQuotedValue(); // => "a-value";
attr.quoteMark; // => null
// Add quotes to an attribute's value.
attr.quoteMark = "'"; // This is all that's required.
attr.toString(); // => "[id='a-value']"
attr.quoted; // => true
// The value is still the same, only the quotes have changed.
attr.value; // => a-value
attr.getQuotedValue(); // => "'a-value'";
// deprecated assignment, no warning because there's no escapes
attr.value = "new-value";
// no quote mark is needed so it is removed
attr.getQuotedValue(); // => "new-value";
// deprecated assignment,
attr.value = "\"a 'single quoted' value\"";
// > (node:27859) DeprecationWarning: Assigning an attribute a value containing characters that might need to be escaped is deprecated. Call attribute.setValue() instead.
attr.getQuotedValue(); // => '"a \'single quoted\' value"';
// quote mark inferred from first and last characters.
attr.quoteMark; // => '"'
// setValue takes options to make manipulating the value simple.
attr.setValue('foo', {smart: true});
// foo doesn't require any escapes or quotes.
attr.toString(); // => '[id=foo]'
attr.quoteMark; // => null
// An explicit quote mark can be specified
attr.setValue('foo', {quoteMark: '"'});
attr.toString(); // => '[id="foo"]'
// preserves quote mark by default
attr.setValue('bar');
attr.toString(); // => '[id="bar"]'
attr.quoteMark = null;
attr.toString(); // => '[id=bar]'
// with no arguments, it preserves quote mark even when it's not a great idea
attr.setValue('a value \n that should be quoted');
attr.toString(); // => '[id=a\\ value\\ \\A\\ that\\ should\\ be\\ quoted]'
// smart preservation with a specified default
attr.setValue('a value \n that should be quoted', {smart: true, preferCurrentQuoteMark: true, quoteMark: "'"});
// => "[id='a value \\A that should be quoted']"
attr.quoteMark = '"';
// => '[id="a value \\A that should be quoted"]'
// this keeps double quotes because it wants to quote the value and the existing value has double quotes.
attr.setValue('this should be quoted', {smart: true, preferCurrentQuoteMark: true, quoteMark: "'"});
// => '[id="this should be quoted"]'
// picks single quotes because the value has double quotes
attr.setValue('a "double quoted" value', {smart: true, preferCurrentQuoteMark: true, quoteMark: "'"});
// => "[id='a "double quoted" value']"
// setPropertyAndEscape lets you do anything you want. Even things that are a bad idea and illegal.
attr.setPropertyAndEscape('value', 'xxxx', 'the password is 42');
attr.value; // => "xxxx"
attr.toString(); // => "[id=the password is 42]"
// Pass a value directly through to the css output without escaping it.
attr.setPropertyWithoutEscape('value', '$REPLACEMENT$');
attr.value; // => "$REPLACEMENT$"
attr.toString(); // => "[id=$REPLACEMENT$]"
```
# 3.1.2
* Fix: Removed dot-prop dependency since it's no longer written in es5.
# 3.1.1
* Fix: typescript definitions weren't in the published package.
# 3.1.0
* Fixed numerous bugs in attribute nodes relating to the handling of comments
and whitespace. There's significant changes to `attrNode.spaces` and `attrNode.raws` since the `3.0.0` release.
* Added `Attribute#offsetOf(part)` to get the offset location of
attribute parts like `"operator"` and `"value"`. This is most
often added to `Attribute#sourceIndex` for error reporting.
# 3.0.0
## Breaking changes
* Some tweaks to the tokenizer/attribute selector parsing mean that whitespace
locations might be slightly different to the 2.x code.
* Better attribute selector parsing with more validation; postcss-selector-parser
no longer uses regular expressions to parse attribute selectors.
* Added an async API (thanks to @jacobp100); the default `process` API is now
async, and the sync API is now accessed through `processSync` instead.
* `process()` and `processSync()` now return a string instead of the Processor
instance.
* Tweaks handling of Less interpolation (thanks to @jwilsson).
* Removes support for Node 0.12.
## Other changes
* `ast()` and `astSync()` methods have been added to the `Processor`. These
return the `Root` node of the selectors after processing them.
* `transform()` and `transformSync()` methods have been added to the
`Processor`. These return the value returned by the processor callback
after processing the selectors.
* Set the parent when inserting a node (thanks to @chriseppstein).
* Correctly adjust indices when using insertBefore/insertAfter (thanks to @tivac).
* Fixes handling of namespaces with qualified tag selectors.
* `process`, `ast` and `transform` (and their sync variants) now accept a
`postcss` rule node. When provided, better errors are generated and selector
processing is automatically set back to the rule selector (unless the `updateSelector` option is set to `false`.)
* Now more memory efficient when tokenizing selectors.
### Upgrade hints
The pattern of:
`rule.selector = processor.process(rule.selector).result.toString();`
is now:
`processor.processSync(rule)`
# 2.2.3
* Resolves an issue where the parser would not reduce multiple spaces between an
ampersand and another simple selector in lossy mode (thanks to @adam-26).
# 2.2.2
* No longer hangs on an unescaped semicolon; instead the parser will throw
an exception for these cases.
# 2.2.1
* Allows a consumer to specify whitespace tokens when creating a new Node
(thanks to @Semigradsky).
# 2.2.0
* Added a new option to normalize whitespace when parsing the selector string
(thanks to @adam-26).
# 2.1.1
* Better unquoted value handling within attribute selectors
(thanks to @evilebottnawi).
# 2.1.0
* Added: Use string constants for all node types & expose them on the main
parser instance (thanks to @Aweary).
# 2.0.0
This release contains the following breaking changes:
* Renamed all `eachInside` iterators to `walk`. For example, `eachTag` is now
`walkTags`, and `eachInside` is now `walk`.
* Renamed `Node#removeSelf()` to `Node#remove()`.
* Renamed `Container#remove()` to `Container#removeChild()`.
* Renamed `Node#raw` to `Node#raws` (thanks to @davidtheclark).
* Now parses `&` as the *nesting* selector, rather than a *tag* selector.
* Fixes misinterpretation of Sass interpolation (e.g. `#{foo}`) as an
id selector (thanks to @davidtheclark).
and;
* Fixes parsing of attribute selectors with equals signs in them
(e.g. `[data-attr="foo=bar"]`) (thanks to @montmanu).
* Adds `quoted` and `raw.unquoted` properties to attribute nodes
(thanks to @davidtheclark).
# 1.3.3
* Fixes an infinite loop on `)` and `]` tokens when they had no opening pairs.
Now postcss-selector-parser will throw when it encounters these lone tokens.
# 1.3.2
* Now uses plain integers rather than `str.charCodeAt(0)` for compiled builds.
# 1.3.1
* Update flatten to v1.x (thanks to @shinnn).
# 1.3.0
* Adds a new node type, `String`, to fix a crash on selectors such as
`foo:bar("test")`.
# 1.2.1
* Fixes a crash when the parser encountered a trailing combinator.
# 1.2.0
* A more descriptive error is thrown when the parser expects to find a
pseudo-class/pseudo-element (thanks to @ashelley).
* Adds support for line/column locations for selector nodes, as well as a
`Node#sourceIndex` method (thanks to @davidtheclark).
# 1.1.4
* Fixes a crash when a selector started with a `>` combinator. The module will
now no longer throw if a selector has a leading/trailing combinator node.
# 1.1.3
* Fixes a crash on `@` tokens.
# 1.1.2
* Fixes an infinite loop caused by using parentheses in a non-pseudo element
context.
# 1.1.1
* Fixes a crash when a backslash ended a selector string.
# 1.1.0
* Adds support for replacing multiple nodes at once with `replaceWith`
(thanks to @jonathantneal).
* Parser no longer throws on sequential IDs and trailing commas, to support
parsing of selector hacks.
# 1.0.1
* Fixes using `insertAfter` and `insertBefore` during iteration.
# 1.0.0
* Adds `clone` and `replaceWith` methods to nodes.
* Adds `insertBefore` and `insertAfter` to containers.
* Stabilises API.
# 0.0.5
* Fixes crash on extra whitespace inside a pseudo selector's parentheses.
* Adds sort function to the container class.
* Enables the parser to pass its input through without transforming.
* Iteration-safe `each` and `eachInside`.
# 0.0.4
* Tidy up redundant duplication.
* Fixes a bug where the parser would loop infinitely on universal selectors
inside pseudo selectors.
* Adds `length` getter and `eachInside`, `map`, `reduce` to the container class.
* When a selector has been removed from the tree, the root node will no longer
cast it to a string.
* Adds node type iterators to the container class (e.g. `eachComment`).
* Adds filter function to the container class.
* Adds split function to the container class.
* Create new node types by doing `parser.id(opts)` etc.
* Adds support for pseudo classes anywhere in the selector.
# 0.0.3
* Adds `next` and `prev` to the node class.
* Adds `first` and `last` getters to the container class.
* Adds `every` and `some` iterators to the container class.
* Add `empty` alias for `removeAll`.
* Combinators are now types of node.
* Fixes the at method so that it is not an alias for `index`.
* Tidy up creation of new nodes in the parser.
* Refactors how namespaces are handled for consistency & less redundant code.
* Refactors AST to use `nodes` exclusively, and eliminates excessive nesting.
* Fixes nested pseudo parsing.
* Fixes whitespace parsing.
# 0.0.2
* Adds support for namespace selectors.
* Adds support for selectors joined by escaped spaces - such as `.\31\ 0`.
# 0.0.1
* Initial release.

# postcss-selector-parser [![test](https://github.com/postcss/postcss-selector-parser/actions/workflows/test.yml/badge.svg)](https://github.com/postcss/postcss-selector-parser/actions/workflows/test.yml)
> Selector parser with built in methods for working with selector strings.
## Install
With [npm](https://npmjs.com/package/postcss-selector-parser) do:
```
npm install postcss-selector-parser
```
## Quick Start
```js
const parser = require('postcss-selector-parser');
const transform = selectors => {
selectors.walk(selector => {
// do something with the selector
console.log(String(selector))
});
};
const transformed = parser(transform).processSync('h1, h2, h3');
```
To normalize selector whitespace:
```js
const parser = require('postcss-selector-parser');
const normalized = parser().processSync('h1, h2, h3', {lossless: false});
// -> h1,h2,h3
```
Async support is provided through `parser.process` and will resolve a Promise
with the resulting selector string.
## API
Please see [API.md](API.md).
## Credits
* Huge thanks to Andrey Sitnik (@ai) for work on PostCSS which helped
accelerate this module's development.

# readdirp [![Weekly downloads](https://img.shields.io/npm/dw/readdirp.svg)](https://github.com/paulmillr/readdirp)
Recursive version of [fs.readdir](https://nodejs.org/api/fs.html#fs_fs_readdir_path_options_callback). Exposes a **stream API** and a **promise API**.
```sh
npm install readdirp
```
```javascript
const readdirp = require('readdirp');
// Use streams to achieve small RAM & CPU footprint.
// 1) Streams example with for-await.
for await (const entry of readdirp('.')) {
const {path} = entry;
console.log(`${JSON.stringify({path})}`);
}
// 2) Streams example, non for-await.
// Print out all JS files along with their size within the current folder & subfolders.
readdirp('.', {fileFilter: '*.js', alwaysStat: true})
.on('data', (entry) => {
const {path, stats: {size}} = entry;
console.log(`${JSON.stringify({path, size})}`);
})
// Optionally call stream.destroy() in `warn()` in order to abort and cause 'close' to be emitted
.on('warn', error => console.error('non-fatal error', error))
.on('error', error => console.error('fatal error', error))
.on('end', () => console.log('done'));
// 3) Promise example. More RAM and CPU than streams / for-await.
const files = await readdirp.promise('.');
console.log(files.map(file => file.path));
// Other options.
readdirp('test', {
fileFilter: '*.js',
directoryFilter: ['!.git', '!*modules']
// directoryFilter: (di) => di.basename.length === 9
type: 'files_directories',
depth: 1
});
```
For more examples, check out `examples` directory.
## API
`const stream = readdirp(root[, options])` — **Stream API**
- Reads given root recursively and returns a `stream` of [entry infos](#entryinfo)
- Optionally can be used like `for await (const entry of stream)` with node.js 10+ (`asyncIterator`).
- `on('data', (entry) => {})` [entry info](#entryinfo) for every file / dir.
- `on('warn', (error) => {})` non-fatal `Error` that prevents a file / dir from being processed. Example: inaccessible to the user.
- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed.
- `on('end')` — we are done. Called when all entries were found and no more will be emitted.
- `on('close')` — stream is destroyed via `stream.destroy()`.
Could be useful if you want to manually abort even on a non fatal error.
At that point the stream is no longer `readable` and no more entries, warning or errors are emitted
- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html)
or the [stream-handbook](https://github.com/substack/stream-handbook)
`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo).
First argument is awalys `root`, path in which to start reading and recursing into subdirectories.
### options
- `fileFilter: ["*.js"]`: filter to include or exclude files. A `Function`, Glob string or Array of glob strings.
- **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
- **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more
information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files.
- **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown.
`['*.json', '*.js']` includes all JavaScript and Json files.
`['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'.
- Directories that do not pass a filter will not be recursed into.
- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into.
- `depth: 5`: depth at which to stop recursing even if more subdirectories are found
- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes.
- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0.
- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat`
### `EntryInfo`
Has the following properties:
- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root)
- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found
- `basename: 'react.js'`: name of the file/directory
- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false`
- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true`
## Changelog
- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks.
Before, it could have entered infinite loop.
- 3.4 (Mar 19, 2020) adds support for directory-based symlinks.
- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping.
- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic.
- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions".
- 3.0 brings huge performance improvements and stream backpressure support.
- Upgrading 2.x to 3.x:
- Signature changed from `readdirp(options)` to `readdirp(root, options)`
- Replaced callback API with promise API.
- Renamed `entryType` option to `type`
- Renamed `entryType: 'both'` to `'files_directories'`
- `EntryInfo`
- Renamed `stat` to `stats`
- Emitted only when `alwaysStat: true`
- `dirent` is emitted instead of `stats` by default with `alwaysStat: false`
- Renamed `name` to `basename`
- Removed `parentDir` and `fullParentDir` properties
- Supported node.js versions:
- 3.x: node 8+
- 2.x: node 0.6+
