In fact, nanomatch passes _all of the spec tests_ from bash, including some that bash still fails. However, since there is no real specification for globs, if you encounter a pattern that yields unexpected match results [after researching previous issues](../../issues), [please let us know](../../issues/new). + +**Basic globbing only** + +Nanomatch supports [basic globbing only](#features), which is limited to `*`, `**`, `?` and regex-like brackets. + +If you need support for the other [bash "expansion" types](#bash-expansion-libs) (in addition to the wildcard matching provided by nanomatch), consider using [micromatch](https://github.com/micromatch/micromatch) instead. _(micromatch >=3.0.0 uses the nanomatch parser and compiler for basic glob matching)_ + +</details> + +## Getting started + +### Installing nanomatch + +**Install with [yarn](https://yarnpkg.com/)** + +```sh +$ yarn add nanomatch +``` + +**Install with [npm](https://npmjs.com)** + +```sh +$ npm install nanomatch +``` + +### Usage + +Add nanomatch to your project using node's `require()` system: + +```js +var nanomatch = require('nanomatch'); + +// the main export is a function that takes an array of strings to match +// and a string or array of patterns to use for matching +nanomatch(list, patterns[, options]); +``` + +**Params** + +* `list` **{String|Array}**: List of strings to perform matches against. This is often a list of file paths. +* `patterns` **{String|Array}**: One or more [glob paterns](#features) to use for matching. +* `options` **{Object}**: Any [supported options](#options) may be passed + +**Examples** + +```js +var nm = require('nanomatch'); +console.log(nm(['a', 'b/b', 'c/c/c'], '*')); +//=> ['a'] + +console.log(nm(['a', 'b/b', 'c/c/c'], '*/*')); +//=> ['b/b'] + +console.log(nm(['a', 'b/b', 'c/c/c'], '**')); +//=> ['a', 'b/b', 'c/c/c'] +``` + +See the [API documentation](#api) for available methods and [options](https://github.com/einaros/options.js). + +## Documentation + +### Escaping + +_Backslashes and quotes_ can be used to escape characters, forcing nanomatch to regard those characters as a literal characters. + +**Backslashes** + +Use backslashes to escape single characters. For example, the following pattern would match `foo/*/bar` exactly: + +```js +'foo/\*/bar' +``` + +The following pattern would match `foo/` followed by a literal `*`, followed by zero or more of any characters besides `/`, followed by `/bar`. + +```js +'foo/\**/bar' +``` + +**Quoted strings** + +Use single or double quotes to escape sequences of characters. For example, the following patterns would match `foo/**/bar` exactly: + +```js +'foo/"**"/bar' +'foo/\'**\'/bar' +"foo/'**'/bar" +``` + +**Matching literal quotes** + +If you need to match quotes literally, you can escape them as well. For example, the following will match `foo/"*"/bar`, `foo/"a"/bar`, `foo/"b"/bar`, or `foo/"c"/bar`: + +```js +'foo/\\"*\\"/bar' +``` + +And the following will match `foo/'*'/bar`, `foo/'a'/bar`, `foo/'b'/bar`, or `foo/'c'/bar`: + +```js +'foo/\\\'*\\\'/bar' +``` + +## API + +### [nanomatch](index.js#L40) + +The main function takes a list of strings and one or more glob patterns to use for matching. + +**Params** + +* `list` **{Array}**: A list of strings to match +* `patterns` **{String|Array}**: One or more glob patterns to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Array}**: Returns an array of matches + +**Example** + +```js +var nm = require('nanomatch'); +nm(list, patterns[, options]); + +console.log(nm(['a.js', 'a.txt'], ['*.js'])); +//=> [ 'a.js' ] +``` + +### [.match](index.js#L106) + +Similar to the main function, but `pattern` must be a string. + +**Params** + +* `list` **{Array}**: Array of strings to match +* `pattern` **{String}**: Glob pattern to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Array}**: Returns an array of matches + +**Example** + +```js +var nm = require('nanomatch'); +nm.match(list, pattern[, options]); + +console.log(nm.match(['a.a', 'a.aa', 'a.b', 'a.c'], '*.a')); +//=> ['a.a', 'a.aa'] +``` + +### [.isMatch](index.js#L167) + +Returns true if the specified `string` matches the given glob `pattern`. + +**Params** + +* `string` **{String}**: String to match +* `pattern` **{String}**: Glob pattern to use for matching. +* `options` **{Object}**: See available [options](#options) for changing how matches are performed +* `returns` **{Boolean}**: Returns true if the string matches the glob pattern. + +**Example** + +```js +var nm = require('nanomatch'); +nm.isMatch(string, pattern[, options]); + +console.log(nm.isMatch('a.a', '*.a')); +//=> true +console.log(nm.isMatch('a.b', '*.a')); +//=> false +``` + +### [.some](index.js#L205) + +Returns true if some of the elements in the given `list` match any of the given glob `patterns`. + +**Params** + +* `list` **{String|Array}**: The string or array of strings to test.
