Micromatch passes _all of the spec tests_ from bash, including some that bash still fails. * **Fast & Performant** - Loads in about 5ms and performs [fast matches](#benchmarks). * **Glob matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories * **[Advanced globbing](#extended-globbing)** - Supports [extglobs](#extglobs), [braces](#braces-1), and [POSIX brackets](#posix-bracket-expressions), and support for escaping special characters with `\` or quotes. * **Accurate** - Covers more scenarios [than minimatch](https://github.com/yarnpkg/yarn/pull/3339) * **Well tested** - More than 5,000 [test assertions](./test) * **Windows support** - More reliable windows support than minimatch and multimatch. * **[Safe](https://github.com/micromatch/braces#braces-is-safe)** - Micromatch is not subject to DoS with brace patterns like minimatch and multimatch. ### Matching features * Support for multiple glob patterns (no need for wrappers like multimatch) * Wildcards (`**`, `*.js`) * Negation (`'!a/*.js'`, `'*!(b).js'`) * [extglobs](#extglobs) (`+(x|y)`, `!(a|b)`) * [POSIX character classes](#posix-bracket-expressions) (`[[: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 [micromatch.isMatch()](#ismatch) instead of `minimatch()`: ```js console.log(micromatch.isMatch('foo', 'b*')); //=> false ``` Use [micromatch.match()](#match) instead of `minimatch.match()`: ```js console.log(micromatch.match(['foo', 'bar'], 'b*')); //=> 'bar' ``` ### From multimatch Same signature: ```js console.log(micromatch(['foo', 'bar', 'baz'], ['f*', '*z'])); //=> ['foo', 'baz'] ``` ## API **Params** * `list` **{String|Array<string>}**: List of strings to match. * `patterns` **{String|Array<string>}**: One or more glob patterns to use for matching. * `options` **{Object}**: See available [options](#options) * `returns` **{Array}**: Returns an array of matches **Example** ```js const mm = require('micromatch'); // mm(list, patterns[, options]); console.log(mm(['a.js', 'a.txt'], ['*.js'])); //=> [ 'a.js' ] ``` ### [.matcher](index.js#L104) Returns a matcher function from the given glob `pattern` and `options`. The returned function takes a string to match as its only argument and returns true if the string is a match. **Params** * `pattern` **{String}**: Glob pattern * `options` **{Object}** * `returns` **{Function}**: Returns a matcher function. **Example** ```js const mm = require('micromatch'); // mm.matcher(pattern[, options]); const isMatch = mm.matcher('*.!(*a)'); console.log(isMatch('a.a')); //=> false console.log(isMatch('a.b')); //=> true ``` ### [.isMatch](index.js#L123) Returns true if **any** of the given glob `patterns` match the specified `string`. **Params** * `str` **{String}**: The string to test. * `patterns` **{String|Array}**: One or more glob patterns to use for matching. * `[options]` **{Object}**: See available [options](#options). * `returns` **{Boolean}**: Returns true if any patterns match `str` **Example** ```js const mm = require('micromatch'); // mm.isMatch(string, patterns[, options]); console.log(mm.isMatch('a.a', ['b.*', '*.a'])); //=> true console.log(mm.isMatch('a.a', 'b.*')); //=> false ``` ### [.not](index.js#L148) Returns a list of strings that _**do not match any**_ of the given `patterns`. **Params** * `list` **{Array}**: Array of strings to match. * `patterns` **{String|Array}**: One or more glob pattern to use for matching. * `options` **{Object}**: See available [options](#options) for changing how matches are performed * `returns` **{Array}**: Returns an array of strings that **do not match** the given patterns. **Example** ```js const mm = require('micromatch'); // mm.not(list, patterns[, options]); console.log(mm.not(['a.a', 'b.b', 'c.c'], '*.a')); //=> ['b.b', 'c.c'] ``` ### [.contains](index.js#L188) Returns true if the given `string` contains the given pattern. Similar to [.isMatch](#isMatch) but the pattern can match any part of the string.
