> Expand POSIX bracket expressions (character classes) in glob patterns.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save expand-brackets
```
## Usage
```js
var brackets = require('expand-brackets');
brackets(string[, options]);
```
**Params**
The main export is a function that takes the following parameters:
* `pattern` **{String}**: the pattern to convert
* `options` **{Object}**: optionally supply an options object
* `returns` **{String}**: returns a string that can be used to create a regex
**Example**
```js
console.log(brackets('[![:lower:]]'));
//=> '[^a-z]'
```
## API
### [brackets](index.js#L29)
Parses the given POSIX character class `pattern` and returns a
string that can be used for creating regular expressions for matching.
**Params**
* `pattern` **{String}**
* `options` **{Object}**
* `returns` **{Object}**
### [.match](index.js#L54)
Takes an array of strings and a POSIX character class pattern, and returns a new array with only the strings that matched the pattern.
**Example**
```js
var brackets = require('expand-brackets');
console.log(brackets.match(['1', 'a', 'ab'], '[[:alpha:]]'));
//=> ['a']
console.log(brackets.match(['1', 'a', 'ab'], '[[:alpha:]]+'));
//=> ['a', 'ab']
```
**Params**
* `arr` **{Array}**: Array of strings to match
* `pattern` **{String}**: POSIX character class pattern(s)
* `options` **{Object}**
* `returns` **{Array}**
### [.isMatch](index.js#L100)
Returns true if the specified `string` matches the given brackets `pattern`.
**Example**
```js
var brackets = require('expand-brackets');
console.log(brackets.isMatch('a.a', '[[:alpha:]].[[:alpha:]]'));
//=> true
console.log(brackets.isMatch('1.2', '[[:alpha:]].[[:alpha:]]'));
//=> false
```
**Params**
* `string` **{String}**: String to match
* `pattern` **{String}**: Poxis pattern
* `options` **{String}**
* `returns` **{Boolean}**
### [.matcher](index.js#L123)
Takes a POSIX character class pattern and returns a matcher function. The returned function takes the string to match as its only argument.
**Example**
```js
var brackets = require('expand-brackets');
var isMatch = brackets.matcher('[[:lower:]].[[:upper:]]');
console.log(isMatch('a.a'));
//=> false
console.log(isMatch('a.A'));
//=> true
```
**Params**
* `pattern` **{String}**: Poxis pattern
* `options` **{String}**
* `returns` **{Boolean}**
### [.makeRe](index.js#L145)
Create a regular expression from the given `pattern`.
**Example**
```js
var brackets = require('expand-brackets');
var re = brackets.makeRe('[[:alpha:]]');
console.log(re);
//=> /^(?:[a-zA-Z])$/
```
**Params**
* `pattern` **{String}**: The pattern to convert to regex.
* `options` **{Object}**
* `returns` **{RegExp}**
### [.create](index.js#L187)
Parses the given POSIX character class `pattern` and returns an object with the compiled `output` and optional source `map`.
**Example**
```js
var brackets = require('expand-brackets');
console.log(brackets('[[:alpha:]]'));
// { options: { source: 'string' },
// input: '[[:alpha:]]',
// state: {},
// compilers:
// { eos: [Function],
// noop: [Function],
// bos: [Function],
// not: [Function],
// escape: [Function],
// text: [Function],
// posix: [Function],
// bracket: [Function],
// 'bracket.open': [Function],
// 'bracket.inner': [Function],
// 'bracket.literal': [Function],
// 'bracket.close': [Function] },
// output: '[a-zA-Z]',
// ast:
// { type: 'root',
// errors: [],
// nodes: [ [Object], [Object], [Object] ] },
// parsingErrors: [] }
```
**Params**
* `pattern` **{String}**
* `options` **{Object}**
* `returns` **{Object}**
## Options
### options.sourcemap
Generate a source map for the given pattern.
**Example**
```js
var res = brackets('[:alpha:]', {sourcemap: true});
console.log(res.map);
// { version: 3,
// sources: [ 'brackets' ],
// names: [],
// mappings: 'AAAA,MAAS',
// sourcesContent: [ '[:alpha:]' ] }
```
### POSIX Character classes
The following named POSIX bracket expressions are supported:
* `[:alnum:]`: Alphanumeric characters (`a-zA-Z0-9]`)
* `[:alpha:]`: Alphabetic characters (`a-zA-Z]`)
* `[:blank:]`: Space and tab (`[ t]`)
* `[:digit:]`: Digits (`[0-9]`)
* `[:lower:]`: Lowercase letters (`[a-z]`)
* `[:punct:]`: Punctuation and symbols. (`[!"#$%&'()*+, -./:;<=>?@ [\]^_``{|}~]`)
* `[:upper:]`: Uppercase letters (`[A-Z]`)
* `[:word:]`: Word characters (letters, numbers and underscores) (`[A-Za-z0-9_]`)
* `[:xdigit:]`: Hexadecimal digits (`[A-Fa-f0-9]`)
See [posix-character-classes](https://github.com/jonschlinkert/posix-character-classes) for more details.
**Not supported**
* [equivalence classes](https://www.gnu.org/software/gawk/manual/html_node/Bracket-Expressions.html) are not supported
* [POSIX.2 collating symbols](https://www.gnu.org/software/gawk/manual/html_node/Bracket-Expressions.html) are not supported
## Changelog
### v2.0.0
**Breaking changes**
* The main export now returns the compiled string, instead of the object returned from the compiler
**Added features**
* Adds a `.create` method to do what the main function did before v2.0.0
### v0.2.0
In addition to performance and matching improvements, the v0.2.0 refactor adds complete POSIX character class support, with the exception of equivalence classes and POSIX.2 collating symbols which are not relevant to node.js usage.
**Added features**
* parser is exposed, so that expand-brackets parsers can be used by upstream parsers (like [micromatch](https://github.com/jonschlinkert/micromatch))
* compiler is exposed, so that expand-brackets compilers can be used by upstream compilers
* source maps
**source map example**
```js
var brackets = require('expand-brackets');
var res = brackets('[:alpha:]');
console.log(res.map);
{ version: 3,
sources: [ 'brackets' ],
names: [],
mappings: 'AAAA,MAAS',
sourcesContent: [ '[:alpha:]' ] }
```

# define-property [![NPM version](https://badge.fury.io/js/define-property.svg)](http://badge.fury.io/js/define-property)
> Define a non-enumerable property on an object.
## Install
Install with [npm](https://www.npmjs.com/)
```sh
$ npm i define-property --save

## Usage
**Params**
* `obj`: The object on which to define the property.
* `prop`: The name of the property to be defined or modified.
* `descriptor`: The descriptor for the property being defined or modified.
```js
var define = require('define-property');
var obj = {};
define(obj, 'foo', function(val) {
return val.toUpperCase();
});
console.log(obj);
//=> {}
console.log(obj.foo('bar'));
//=> 'BAR'
```
**get/set**

define(obj, 'foo', {
get: function() {},
set: function() {}

> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
## Usage
```js
const isDescriptor = require('is-descriptor');
const assert = require('assert');
assert.equal(isDescriptor({ value: 'foo' }), true);
assert.equal(isDescriptor({ get() {}, set() {} }), true);
assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
```
You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
```js
const obj = { foo: 'abc' };
Object.defineProperty(obj, 'bar', {
value: 'xyz'
});
assert.equal(isDescriptor(obj, 'foo'), true);
assert.equal(isDescriptor(obj, 'bar'), true);
```
## Examples
### value type
`false` when not an object
```js
assert.equal(isDescriptor('a'), false);
assert.equal(isDescriptor(null), false);
assert.equal(isDescriptor([]), false);
```
### data descriptor
`true` when the object has valid properties with valid values.
```js
assert.equal(isDescriptor({ value: 'foo' }), true);
assert.equal(isDescriptor({ value() {} }), true);
```
`false` when the object has invalid properties
```js
assert.equal(isDescriptor({ value: 'foo', enumerable: 'baz' }), false);
assert.equal(isDescriptor({ value: 'foo', configurable: 'baz' }), false);
assert.equal(isDescriptor({ value: 'foo', get() {} }), false);
assert.equal(isDescriptor({ get() {}, value() {} }), false);
```
`false` when a value is not the correct type
```js
assert.equal(isDescriptor({ value: 'foo', enumerable: 'foo' }), false);
assert.equal(isDescriptor({ value: 'foo', configurable: 'foo' }), false);
assert.equal(isDescriptor({ value: 'foo', writable: 'foo' }), false);
```
### accessor descriptor
`true` when the object has valid properties with valid values.
```js

`false` when an accessor is not a function
```js
assert.equal(isDescriptor({ get() {}, set: 'baz' }), false);
assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
assert.equal(isDescriptor({ get: 'foo', bar: 'baz' }), false);
assert.equal(isDescriptor({ get: 'foo', set: 'baz' }), false);

`false` when a value is not the correct type
```js
assert.equal(isDescriptor({ get() {}, set() {}, enumerable: 'foo' }), false);
assert.equal(isDescriptor({ set() {}, configurable: 'foo' }), false);
