We now use webpack instead of SystemJS, effectively bundling modules into one file (plus commons chunks) for every entry point. This results in a much smaller extension size (almost half). Furthermore we use yarn/npm even for extension run-time dependencies. This relieves us from manually vendoring and building dependencies. It's also easier to understand for new developers familiar with node.

## Example
|
|
|
|
```js
|
|
var expand = require('brace-expansion');
|
|
|
|
expand('file-{a,b,c}.jpg')
|
|
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
|
|
|
|
expand('-v{,,}')
|
|
// => ['-v', '-v', '-v']
|
|
|
|
expand('file{0..2}.jpg')
|
|
// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
|
|
|
|
expand('file-{a..c}.jpg')
|
|
// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
|
|
|
|
expand('file{2..0}.jpg')
|
|
// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
|
|
|
|
expand('file{0..4..2}.jpg')
|
|
// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
|
|
|
|
expand('file-{a..e..2}.jpg')
|
|
// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
|
|
|
|
expand('file{00..10..5}.jpg')
|
|
// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
|
|
|
|
expand('{{A..C},{a..c}}')
|
|
// => ['A', 'B', 'C', 'a', 'b', 'c']
|
|
|
|
expand('ppp{,config,oe{,conf}}')
|
|
// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
|
|
```
|
|
|
|
## API
|
|
|
|
```js
|
|
var expand = require('brace-expansion');
|
|
```
|
|
|
|
### var expanded = expand(str)
|
|
|
|
Return an array of all possible and valid expansions of `str`. If none are
|
|
found, `[str]` is returned.
|
|
|
|
Valid expansions are:
|
|
|
|
```js
|
|
/^(.*,)+(.+)?$/
|
|
// {a,b,...}
|
|
```
|
|
|
|
A comma seperated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
|
|
|
|
```js
|
|
/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
|
|
// {x..y[..incr]}
|
|
```
|
|
|
|
A numeric sequence from `x` to `y` inclusive, with optional increment.
|
|
If `x` or `y` start with a leading `0`, all the numbers will be padded
|
|
to have equal length. Negative numbers and backwards iteration work too.
|
|
|
|
```js
|
|
/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
|
|
// {x..y[..incr]}
|
|
```
|
|
|
|
An alphabetic sequence from `x` to `y` inclusive, with optional increment.
|
|
`x` and `y` must be exactly one character, and if given, `incr` must be a
|
|
number.
|
|
|
|
For compatibility reasons, the string `${` is not eligible for brace expansion.
|
|
|
|
## Installation
|
|
|
|
With [npm](https://npmjs.org) do:
|
|
|
|
```bash
|
|
npm install brace-expansion
|
|
```
