# multimatch [![Build Status](https://travis-ci.org/sindresorhus/multimatch.svg?branch=master)](https://travis-ci.org/sindresorhus/multimatch)
> Extends [`minimatch.match()`](https://github.com/isaacs/minimatch#minimatchmatchlist-pattern-options) with support for multiple patterns
## Install
```sh
$ npm install --save multimatch
```
## Usage
```js
var multimatch = require('multimatch');
multimatch(['unicorn', 'cake', 'rainbows'], ['*', '!cake']);
//=> ['unicorn', 'rainbows']
```
See the [tests](https://github.com/sindresorhus/multimatch/blob/master/test.js) for more usage examples and expected matches.
## API
Same as [`minimatch.match()`](https://github.com/isaacs/minimatch#minimatchmatchlist-pattern-options) except for `pattern` also accepting an array.
```js
var results = multimatch(paths, patterns);
```
The return value is an array of matching paths.
## How multiple patterns work
Positive patterns (e.g. `foo` or `*`) add to the results, while negative patterns (e.g. `!foo`) subtract from the results.
Therefore a lone negation (e.g. `['!foo']`) will never match anything use `['*', '!foo']` instead.
## Globbing patterns
Just a quick overview.
- `*` matches any number of characters, but not `/`
- `?` matches a single character, but not `/`
- `**` matches any number of characters, including `/`, as long as it's the only thing in a path part
- `{}` allows for a comma-separated list of "or" expressions
- `!` at the beginning of a pattern will negate the match
