anymatch [](https://travis-ci.org/micromatch/anymatch) [](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.__
|
||
|
||
|
||
Usage
|
||
-----
|
||
```sh
|
||
npm install anymatch
|
||
```
|
||
|
||
#### anymatch(matchers, testString, [returnIndex], [options])
|
||
* __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.
|
||
* __options__: (_Object_ [optional]_) Any of the [picomatch](https://github.com/micromatch/picomatch#options) options.
|
||
* __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.
|
||
|
||
```js
|
||
const anymatch = require('anymatch');
|
||
|
||
const matchers = [ 'path/to/file.js', 'path/anyjs/**/*.js', /foo.js$/, string => string.includes('bar') && 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', {returnIndex: true}); // 2
|
||
anymatch(matchers, 'path/anyjs/foo.js', {returnIndex: true}); // 1
|
||
|
||
// any picomatc
|
||
|
||
// 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
|
||
|
||
const matcher = anymatch(matchers);
|
||
['foo.js', 'bar.js'].filter(matcher); // [ 'foo.js' ]
|
||
anymatch master* ❯
|
||
|
||
```
|
||
|
||
#### 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#filter` callback.
|
||
|
||
```js
|
||
var matcher = anymatch(matchers);
|
||
|
||
matcher('path/to/file.js'); // true
|
||
matcher('path/anyjs/baz.js', true); // 1
|
||
|
||
['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
|
||
```

Changelog
|
||
----------
|
||
[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
|
||
|
||
- **v3.0:** Removed `startIndex` and `endIndex` arguments. Node 8.x-only.
|
||
- **v2.0:** [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).
|
||
- **v1.2:** 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).
