anymatch [](https://travis-ci.org/es128/anymatch) [](https://coveralls.io/r/es128/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.

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
|
|
```
|
|
|
|
#### 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/es128/anymatch/releases)
|
|
|
|
NOTE: As of v1.2.0, anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
|
|
for glob pattern matching. The glob matching behavior should be functionally
|
|
equivalent to the commonly used [minimatch](https://github.com/isaacs/minimatch)
|
|
library (aside from some fixed bugs and greater performance), so a major
|
|
version bump wasn't merited. Issues with glob pattern matching should be
|
|
reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).
