anymatch

anymatch

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

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 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.

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(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.

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

• v3.0: Removed startIndex and endIndex arguments. Node 8.x-only.
• v2.0: 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 for glob pattern matching. Issues with glob pattern matching should be reported directly to the micromatch issue tracker.

micromatch

Micromatch is a glob matching library that offers a variety of powerful features and optimizations. It is more extensive than anymatch, providing more fine-grained control over pattern matching and glob expansion.

minimatch

Minimatch is a minimal matching utility that implements glob matching in JavaScript. It is the matcher used by npm itself and is similar to anymatch but with a simpler API and fewer features.

multimatch

Multimatch extends minimatch to allow multiple patterns to be specified. It is similar to anymatch in that it can match against multiple patterns, but it is built on top of minimatch.

picomatch

Picomatch is a small, fast, and powerful glob matcher with a simple API. It is similar to anymatch but focuses on performance and is suitable for runtime usage.
