In fact, micromatch passes _all of the spec tests_ from bash, including some that bash still fails. * [Faster matching](#benchmarks), from a combination of optimized glob patterns, faster algorithms, and regex caching. * [Micromatch is safer](https://github.com/micromatch/braces#braces-is-safe), and is not subject to DoS with brace patterns, like minimatch and multimatch. * More reliable windows support than minimatch and multimatch. ### Matching features * Support for multiple glob patterns (no need for wrappers like multimatch) * Wildcards (`**`, `*.js`) * Negation (`'!a/*.js'`, `'*!(b).js']`) * [extglobs](https://github.com/micromatch/extglob) (`+(x|y)`, `!(a|b)`) * [POSIX character classes](https://github.com/micromatch/expand-brackets) (`[[:alpha:][:digit:]]`) * [brace expansion](https://github.com/micromatch/braces) (`foo/{1..5}.md`, `bar/{a,b,c}.js`) * regex character classes (`foo-[1-5].js`) * regex logical "or" (`foo/(abc|xyz).js`) You can mix and match these features to create whatever patterns you need! ## Switching to micromatch There is one notable difference between micromatch and minimatch in regards to how backslashes are handled. See [the notes about backslashes](#backslashes) for more information. ### From minimatch Use [mm.isMatch()](#ismatch) instead of `minimatch()`: ```js mm.isMatch('foo', 'b*'); //=> false ``` Use [mm.match()](#match) instead of `minimatch.match()`: ```js mm.match(['foo', 'bar'], 'b*'); //=> 'bar' ``` ### From multimatch Same signature: ```js mm(['foo', 'bar', 'baz'], ['f*', '*z']); //=> ['foo', 'baz'] ``` ## API ### [micromatch](index.js#L41) 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 mm = require('micromatch'); mm(list, patterns[, options]); console.log(mm(['a.js', 'a.txt'], ['*.js'])); //=> [ 'a.js' ] ``` ### [.match](index.js#L93) 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 mm = require('micromatch'); mm.match(list, pattern[, options]); console.log(mm.match(['a.a', 'a.aa', 'a.b', 'a.c'], '*.a')); //=> ['a.a', 'a.aa'] ``` ### [.isMatch](index.js#L154) 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 mm = require('micromatch'); mm.isMatch(string, pattern[, options]); console.log(mm.isMatch('a.a', '*.a')); //=> true console.log(mm.isMatch('a.b', '*.a')); //=> false ``` ### [.some](index.js#L192) Returns true if some of the strings in the given `list` match any of the given glob `patterns`. **Params** * `list` **{String|Array}**: The string or array of strings to test. Returns as soon as the first match is found. * `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` **{Boolean}**: Returns true if any patterns match `str` **Example** ```js var mm = require('micromatch'); mm.some(list, patterns[, options]); console.log(mm.some(['foo.js', 'bar.js'], ['*.js', '!foo.js'])); // true console.log(mm.some(['foo.js'], ['*.js', '!foo.js'])); // false ``` ### [.every](index.js#L228) Returns true if every strin
