## Start matching!
## Quickstart
```js
var mm = require('micromatch');
console.log(mm(['']))
mm(list, patterns[, options]);
```
***
The [main export](#micromatch) takes a list of strings and one or more glob patterns:
### Features
```js
console.log(mm(['foo', 'bar', 'qux'], ['f*', 'b*']));
//=> ['foo', 'bar']
```
* [Drop-in replacement](#switch-from-minimatch) for [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch)
* Built-in support for multiple glob patterns, like `['foo/*.js', '!bar.js']`
* [Brace Expansion](https://github.com/jonschlinkert/braces) (`foo/bar-{1..5}.md`, `one/{two,three}/four.md`)
* Typical glob patterns, like `**/*`, `a/b/*.js`, or `['foo/*.js', '!bar.js']`
* Methods like `.isMatch()`, `.contains()` and `.any()`
Use [.isMatch()](#ismatch) to get true/false:
**Extended globbing features:**
```js
console.log(mm.isMatch('foo', 'f*'));
//=> true
```
* Logical `OR` (`foo/bar/(abc|xyz).js`)
* Regex character classes (`foo/bar/baz-[1-5].js`)
* POSIX [bracket expressions](https://github.com/jonschlinkert/expand-brackets) (`**/[[:alpha:][:digit:]]/`)
* [extglobs](https://github.com/jonschlinkert/extglob) (`**/+(x|y)`, `!(a|b)`, etc).
[Switching](#switching-to-micromatch) from minimatch and multimatch is easy!
You can combine these to create whatever matching patterns you need.
## Why use micromatch?
**Example**
> micromatch is a [drop-in replacement](#switching-to-micromatch) for minimatch and multimatch
```js
// double-negation!
mm(['fa', 'fb', 'f', 'fo'], '!(f!(o))');
//=> ['fo']
```
* Supports all of the same matching features as [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch)
* Micromatch uses [snapdragon](https://github.com/jonschlinkert/snapdragon) for parsing and compiling globs, which provides granular control over the entire conversion process in a way that is easy to understand, reason about, and maintain.
* More accurate, with more than 36,000 [test assertions](./test) to prove it.
* More complete support for the Bash 4.3 specification than minimatch and multimatch. 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.
## Why switch to micromatch?
### Matching features
* Native support for multiple glob patterns, no need for wrappers like [multimatch](https://github.com/sindresorhus/multimatch)
* [10-55x faster](#benchmarks) and more performant than [minimatch](https://github.com/isaacs/minimatch) and [multimatch](https://github.com/sindresorhus/multimatch). This is achieved through a combination of caching and regex optimization strategies, a fundamentally different approach than minimatch.
* More extensive support for the Bash 4.3 specification
* More complete extglob support
* Extensive [unit tests](./test) (approx. 1,300 tests). Minimatch fails many of the tests.
* Support for multiple glob patterns (no need for wrappers like multimatch)
* Wildcards (`**`, `*.js`)
* Negation (`'!a/*.js'`, `'*!(b).js']`)
* [extglobs](https://github.com/jonschlinkert/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`)
### Switch from minimatch
You can mix and match these features to create whatever patterns you need!
Use `mm.isMatch()` instead of `minimatch()`:
## 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.

```
### .isMatch
### [.contains](index.js#L389)
```js
mm.isMatch(filepath, globString);
```
Returns true if the given `string` contains the given pattern. Similar to [.isMatch](#isMatch) but the pattern can match any part of the string.
Returns true if a file path matches the given glob pattern.
**Params**
* `str` **{String}**: The string to match.
* `patterns` **{String|Array}**: Glob pattern to use for matching.
* `options` **{Object}**: See available [options](#options) for changing how matches are performed
* `returns` **{Boolean}**: Returns true if the patter matches any part of `str`.
**Example**
```js
mm.isMatch('.verb.md', '*.md');
//=> false
var mm = require('micromatch');
mm.contains(string, pattern[, options]);
mm.isMatch('.verb.md', '*.md', {dot: true});
console.log(mm.contains('aa/bb/cc', '*b'));
//=> true
console.log(mm.contains('aa/bb/cc', '*d'));
//=> false
```
### .contains
### [.matchKeys](index.js#L445)
Returns true if any part of a file path matches the given glob pattern. Think of this is "has path" versus "is path".
Filter the keys of the given object with the given `glob` pattern and `options`. Does not attempt to match nested keys. If you need this feature, use [glob-object](https://github.com/jonschlinkert/glob-object) instead.
**Params**
* `object` **{Object}**: The object with keys to filter.
* `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` **{Object}**: Returns an object with only keys that match the given patterns.
**Example**
`.isMatch()` would return false for both of the following:
```js
mm.contains('a/b/c', 'a/b');
//=> true
var mm = require('micromatch');
mm.matchKeys(object, patterns[, options]);
mm.contains('a/b/c', 'a/*');
//=> true
var obj = { aa: 'a', ab: 'b', ac: 'c' };
console.log(mm.matchKeys(obj, '*b'));
//=> { ab: 'b' }
```
### .matcher
### [.matcher](index.js#L474)
Returns a function for matching using the supplied pattern. e.g. create your own "matcher". The advantage of this method is that the pattern can be compiled outside of a loop.
Returns a memoized 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.
**Pattern**
**Params**
Can be any of the following:
* `pattern` **{String}**: Glob pattern
* `options` **{Object}**: See available [options](#options) for changing how matches are performed.
* `returns` **{Function}**: Returns a matcher function.
* `glob/string`
* `regex`
* `function`
**Example**
```js
var isMatch = mm.matcher('*.md');
var files = [];
var mm = require('micromatch');
mm.matcher(pattern[, options]);
['a.md', 'b.txt', 'c.md'].forEach(function(fp) {
if (isMatch(fp)) {
files.push(fp);
}
});
var isMatch = mm.matcher('*.!(*a)');
console.log(isMatch('a.a'));
//=> false
console.log(isMatch('a.b'));
//=> true
```
### .filter
### [.makeRe](index.js#L542)
Returns a function that can be passed to `Array#filter()`.
Create a regular expression from the given glob `pattern`.
**Params**
* `patterns` **{String|Array}**:
* `pattern` **{String}**: A glob pattern to convert to regex.
* `options` **{Object}**: See available [options](#options) for changing how matches are performed.
* `returns` **{RegExp}**: Returns a regex created from the given pattern.
**Examples**
**Example**
Single glob:
```js
var fn = mm.filter('*.md');
['a.js', 'b.txt', 'c.md'].filter(fn);
//=> ['c.md']
var mm = require('micromatch');
mm.makeRe(pattern[, options]);
var fn = mm.filter('[a-c]');
['a', 'b', 'c', 'd', 'e'].filter(fn);
//=> ['a', 'b', 'c']
console.log(mm.makeRe('*.js'));
//=> /^(?:(\.[\\\/])?(?!\.)(?=.)[^\/]*?\.js)$/
```
Array of glob patterns:
### [.braces](index.js#L585)
Expand the given brace `pattern`.
**Params**
* `pattern` **{String}**: String with brace pattern to expand.
* `options` **{Object}**: Any [options](#options) to change how expansion is performed. See the [braces](https://github.com/micromatch/braces) library for all available options.
* `returns` **{Array}**
**Example**
```js
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];
var mm = require('micromatch');
console.log(mm.braces('foo/{a,b}/bar'));
//=> ['foo/(a|b)/bar']
var fn = mm.filter(['{1..10}', '![7-9]', '!{3..4}']);
arr.filter(fn);
//=> [1, 2, 5, 6, 10]
console.log(mm.braces('foo/{a,b}/bar', {expand: true}));
//=> ['foo/(a|b)/bar']
```
_(Internally this function generates the matching function by using the [matcher](#matcher) method. You can use the [matcher](#matcher) method directly to create your own filter function)_
### [.create](index.js#L649)
### .any
Parses the given glob `pattern` and returns an array of abstract syntax trees (ASTs), with the compiled `output` and optional source `map` on each AST.
Returns true if a file path matches any of the given patterns.

### braces
#### brace expansion
Brace patterns can be used to match specific ranges or sets of characters. For example, the pattern `*/{1..3}/*` would match any of following strings:
In simple cases, brace expansion appears to work the same way as the logical `OR` operator. For example, `(a|b)` will achieve the same result as `{a,b}`.
```
foo/1/bar
foo/2/bar
foo/3/bar
baz/1/qux
baz/2/qux
baz/3/qux
```
Here are some powerful features unique to brace expansion (versus character classes):
Visit [braces](https://github.com/micromatch/braces) to see the full range of features and options related to brace expansion, or to create brace matching or expansion related issues.
* range expansion: `a{1..3}b/*.js` expands to: `['a1b/*.js', 'a2b/*.js', 'a3b/*.js']`

Whenever possible parsing behavior for patterns is based on globbing specifications in Bash 4.3. Patterns that aren't described by Bash follow wildmatch spec (used by git).
### Bash 4.3 parity
## Benchmarks
Whenever possible matching behavior is based on behavior Bash 4.3, which is mostly consistent with minimatch.
Run the [benchmarks](./benchmark):
However, it's suprising how many edge cases and rabbit holes there are with glob matching, and since there is no real glob specification, and micromatch is more accurate than both Bash and minimatch, there are cases where best-guesses were made for behavior. In a few cases where Bash had no answers, we used wildmatch (used by git) as a fallback.
```bash
node benchmark
```
### Backslashes
As of July 15, 2016:
There is an important, notable difference between minimatch and micromatch _in regards to how backslashes are handled_ in glob patterns.
```bash
#1: basename-braces
micromatch x 26,420 ops/sec ±0.89% (91 runs sampled)
minimatch x 3,507 ops/sec ±0.64% (97 runs sampled)
* Micromatch exclusively and explicitly reserves backslashes for escaping characters in a glob pattern, even on windows. This is consistent with bash behavior.
* Minimatch converts all backslashes to forward slashes, which means you can't use backslashes to escape any characters in your glob patterns.
#2: basename
micromatch x 25,315 ops/sec ±0.82% (93 runs sampled)
minimatch x 4,398 ops/sec ±0.86% (94 runs sampled)
We made this decision for micromatch for a couple of reasons:
#3: braces-no-glob
micromatch x 341,254 ops/sec ±0.78% (93 runs sampled)
minimatch x 30,197 ops/sec ±1.12% (91 runs sampled)
* consistency with bash conventions.
* glob patterns are not filepaths. They are a type of [regular language](https://en.wikipedia.org/wiki/Regular_language) that is converted to a JavaScript regular expression. Thus, when forward slashes are defined in a glob pattern, the resulting regular expression will match windows or POSIX path separators just fine.
#4: braces
micromatch x 54,649 ops/sec ±0.74% (94 runs sampled)
minimatch x 3,095 ops/sec ±0.82% (95 runs sampled)
**A note about joining paths to globs**
#5: immediate
micromatch x 16,719 ops/sec ±0.79% (95 runs sampled)
minimatch x 4,348 ops/sec ±0.86% (96 runs sampled)
Note that when you pass something like `path.join('foo', '*')` to micromatch, you are creating a filepath and expecting it to still work as a glob pattern. This causes problems on windows, since the `path.sep` is `\\`.
#6: large
micromatch x 721 ops/sec ±0.77% (94 runs sampled)
minimatch x 17.73 ops/sec ±1.08% (50 runs sampled)
In other words, since `\\` is reserved as an escape character in globs, on windows `path.join('foo', '*')` would result in `foo\\*`, which tells micromatch to match `*` as a literal character. This is the same behavior as bash.
#7: long
micromatch x 5,051 ops/sec ±0.87% (97 runs sampled)
minimatch x 628 ops/sec ±0.83% (94 runs sampled)
## Contributing
#8: mid

minimatch x 1,923 ops/sec ±0.84% (95 runs sampled)
All contributions are welcome! Please read [the contributing guide](.github/contributing.md) to get started.
#9: multi-patterns
micromatch x 22,440 ops/sec ±0.97% (94 runs sampled)
minimatch x 2,481 ops/sec ±1.10% (94 runs sampled)
**Bug reports**
#10: no-glob
micromatch x 722,823 ops/sec ±1.30% (87 runs sampled)
minimatch x 52,967 ops/sec ±1.09% (94 runs sampled)
Please create an issue if you encounter a bug or matching behavior that doesn't seem correct. If you find a matching-related issue, please:
#11: range
micromatch x 243,471 ops/sec ±0.79% (94 runs sampled)
minimatch x 11,736 ops/sec ±0.82% (96 runs sampled)
* [research existing issues first](../../issues) (open and closed)
* visit the [GNU Bash documentation](https://www.gnu.org/software/bash/manual/) to see how Bash deals with the pattern
* visit the [minimatch](https://github.com/isaacs/minimatch) documentation to cross-check expected behavior in node.js
* if all else fails, since there is no real specification for globs we will probably need to discuss expected behavior and decide how to resolve it. which means any detail you can provide to help with this discussion would be greatly appreciated.
#12: shallow
micromatch x 190,874 ops/sec ±0.98% (95 runs sampled)
minimatch x 21,699 ops/sec ±0.81% (97 runs sampled)
**Platform issues**
#13: short
micromatch x 496,393 ops/sec ±3.86% (90 runs sampled)
minimatch x 53,765 ops/sec ±0.75% (95 runs sampled)
```
It's important to us that micromatch work consistently on all platforms. If you encounter any platform-specific matching or path related issues, please let us know (pull requests are also greatly appreciated).
