@isaacs/brace-expansion

A hybrid CJS/ESM TypeScript fork of brace-expansion.

Brace expansion, as known from sh/bash, in JavaScript.

Example

import { expand } from '@isaacs/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

import { expand } from '@isaacs/brace-expansion'

const expanded = expand(str)

Return an array of all possible and valid expansions of str. If none are found, [str] is returned.

Valid expansions are:

/^(.*,)+(.+)?$/
// {a,b,...}

A comma separated list of options, like {a,b} or {a,{b,c}} or {,a,}.

/^-?\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.

/^-?\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.
