## What is nanomatch?
Nanomatch is a fast and accurate glob matcher with full support for standard Bash glob features, including the following "metacharacters": `*`, `**`, `?` and `[...]`.
**Learn more**
* [Getting started](#getting-started): learn how to install and begin using nanomatch
* [Features](#features): jump to info about supported patterns, and a glob matching reference
* [API documentation](#api): jump to available options and methods
* [Unit tests](test): visit unit tests. there is no better way to learn a code library than spending time the unit tests. Nanomatch has 36,000 unit tests - go become a glob matching ninja!
How is this different?
**Speed and accuracy**
Nanomatch uses [snapdragon](https://github.com/jonschlinkert/snapdragon) for parsing and compiling globs, which results in:
* Granular control over the entire conversion process in a way that is easy to understand, reason about, and customize.
* Faster matching, from a combination of optimized glob patterns and (optional) caching.
* Much greater accuracy than minimatch. 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/jonschlinkert/micromatch) instead. _(micromatch >=3.0.0 uses the nanomatch parser and compiler for basic glob matching)_
## 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'
```

### [.clearCache](index.js#L726)
Clear the regex cache.
**Example**

## Options
basename
### options.basename
Allow glob patterns without slashes to match a file path based on its basename. Same behavior as [minimatch](https://github.com/isaacs/minimatch) option `matchBase`.
Type: `Boolean`
Default: `false`
**Example**
```js
nm(['a/b.js', 'a/c.md'], '*.js');
//=> []
nm(['a/b.js', 'a/c.md'], '*.js', {matchBase: true});
//=> ['a/b.js']
```
bash
### options.bash
Enabled by default, this option enforces bash-like behavior with stars immediately following a bracket expression. Bash bracket expressions are similar to regex character classes, but unlike regex, a star following a bracket expression **does not repeat the bracketed characters**. Instead, the star is treated the same as an other star.
Type: `Boolean`
Default: `true`
**Example**
```js
var files = ['abc', 'ajz'];
console.log(nm(files, '[a-c]*'));
//=> ['abc', 'ajz']
console.log(nm(files, '[a-c]*', {bash: false}));
```
cache
### options.cache
Disable regex and function memoization.
Type: `Boolean`
Default: `undefined`
dot
### options.dot
Match dotfiles. Same behavior as [minimatch](https://github.com/isaacs/minimatch) option `dot`.
Type: `Boolean`
Default: `false`
failglob
### options.failglob
Similar to the `--failglob` behavior in Bash, throws an error when no matches are found.
Type: `Boolean`
Default: `undefined`
ignore
### options.ignore
String or array of glob patterns to match files to ignore.
Type: `String|Array`
Default: `undefined`
matchBase
### options.matchBase
Alias for [options.basename](#options-basename).
nocase
### options.nocase
Use a case-insensitive regex for matching files. Same behavior as [minimatch](https://github.com/isaacs/minimatch).
Type: `Boolean`
Default: `undefined`
nodupes
### options.nodupes
Remove duplicate elements from the result array.
Type: `Boolean`
Default: `true` (enabled by default)
**Example**
Example of using the `unescape` and `nodupes` options together:
```js
nm.match(['a/b/c', 'a/b/c'], '**');
//=> ['abc']
nm.match(['a/b/c', 'a/b/c'], '**', {nodupes: false});
//=> ['a/b/c', 'a/b/c']
```
nonegate
### options.noglobstar
Disable matching with globstars (`**`).
Type: `Boolean`
Default: `undefined`
```js
nm(['a/b', 'a/b/c', 'a/b/c/d'], 'a/**');
//=> ['a/b', 'a/b/c', 'a/b/c/d']
nm(['a/b', 'a/b/c', 'a/b/c/d'], 'a/**', {noglobstar: true});
//=> ['a/b']
```
nonegate
### options.nonegate
Disallow negation (`!`) patterns, and treat leading `!` as a literal character to match.
Type: `Boolean`
Default: `undefined`
nonull
### options.nonull
Alias for [options.nullglob](#options-nullglob).
nullglob
### options.nullglob
If `true`, when no matches are found the actual (arrayified) glob pattern is returned instead of an empty array. Same behavior as [minimatch](https://github.com/isaacs/minimatch) option `nonull`.
Type: `Boolean`
Default: `undefined`
snapdragon
### options.snapdragon
Pass your own instance of [snapdragon](https://github.com/jonschlinkert/snapdragon) to customize parsers or compilers.
Type: `Object`
Default: `undefined`
snapdragon
### options.sourcemap
Generate a source map by enabling the `sourcemap` option with the `.parse`, `.compile`, or `.create` methods.
**Examples**
```js
var nm = require('nanomatch');
var res = nm.create('abc/*.js', {sourcemap: true});
console.log(res.map);
// { version: 3,
// sources: [ 'string' ],
// names: [],
// mappings: 'AAAA,GAAG,EAAC,iBAAC,EAAC,EAAE',
// sourcesContent: [ 'abc/*.js' ] }
var ast = nm.parse('abc/**/*.js');
var res = nm.compile(ast, {sourcemap: true});
console.log(res.map);
// { version: 3,
// sources: [ 'string' ],
// names: [],
// mappings: 'AAAA,GAAG,EAAC,2BAAE,EAAC,iBAAC,EAAC,EAAE',
// sourcesContent: [ 'abc/**/*.js' ] }
```
unescape
### options.unescape
Remove backslashes from returned matches.
Type: `Boolean`
Default: `undefined`
**Example**
In this example we want to match a literal `*`:
```js
nm.match(['abc', 'a\\*c'], 'a\\*c');
//=> ['a\\*c']
nm.match(['abc', 'a\\*c'], 'a\\*c', {unescape: true});
//=> ['a*c']
```
unixify
### options.unixify
Convert path separators on returned files to posix/unix-style forward slashes.
Type: `Boolean`
Default: `true`
**Example**
```js
nm.match(['a\\b\\c'], 'a/**');
//=> ['a/b/c']
nm.match(['a\\b\\c'], {unixify: false});
//=> ['a\\b\\c']
```
## Features
Nanomatch has full support for standard Bash glob features, including the following "metacharacters": `*`, `**`, `?` and `[...]`.
Here are some examples of how they work:
| **Pattern** | **Description** |
| --- | --- |
| `*` | Matches any string except for `/`, leading `.`, or `/.` inside a path |
| `**` | Matches any string including `/`, but not a leading `.` or `/.` inside a path. More than two stars (e.g. `***` is treated the same as one star, and `**` loses its special meaning | when it's not the only thing in a path segment, per Bash specifications) |
| `foo*` | Matches any string beginning with `foo` |
| `*bar*` | Matches any string containing `bar` (beginning, middle or end) |
| `*.min.js` | Matches any string ending with `.min.js` |
| `[abc]*.js` | Matches any string beginning with `a`, `b`, or `c` and ending with `.js` |
| `abc?` | Matches `abcd` or `abcz` but not `abcde` |
The exceptions noted for `*` apply to all patterns that contain a `*`.
**Not supported**
The following extended-globbing features are not supported:
* [brace expansion](https://github.com/jonschlinkert/braces) (e.g. `{a,b,c}`)
* [extglobs](https://github.com/jonschlinkert/extglob) (e.g. `@(a|!(c|d))`)
* [POSIX brackets](https://github.com/jonschlinkert/expand-brackets) (e.g. `[[:alpha:][:digit:]]`)
If you need any of these features consider using [micromatch](https://github.com/jonschlinkert/micromatch) instead.
## Bash expansion libs
Nanomatch is part of a suite of libraries aimed at bringing the power and expressiveness of [Bash's](https://www.gnu.org/software/bash/) matching and expansion capabilities to JavaScript, _and - as you can see by the [benchmarks](#benchmarks) - without sacrificing speed_.
| **Related library** | **Matching Type** | **Example** | **Description** |

| `nanomatch` (you are here) | Wildcards | `*` | [Filename expansion](https://www.gnu.org/software/bash/manual/html_node/Filename-Expansion.html#Filename-Expansion), also referred to as globbing and pathname expansion, allows the use of [wildcards](#features) for matching. |
| [expand-tilde](https://github.com/jonschlinkert/expand-tilde) | Tildes | `~` | [Tilde expansion](https://www.gnu.org/software/bash/manual/html_node/Tilde-Expansion.html#Tilde-Expansion) converts the leading tilde in a file path to the user home directory. |
