If none are 57 found, `[str]` is returned. 58 59 Valid expansions are: 60 61 ```js 62 /^(.*,)+(.+)?$/ 63 // {a,b,...} 64 ``` 65 66 A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`. 67 68 ```js 69 /^-?\d+\.\.-?\d+(\.\.-?\d+)?$/ 70 // {x..y[..incr]} 71 ``` 72 73 A numeric sequence from `x` to `y` inclusive, with optional increment. 74 If `x` or `y` start with a leading `0`, all the numbers will be padded 75 to have equal length. Negative numbers and backwards iteration work too. 76 77 ```js 78 /^-?\d+\.\.-?\d+(\.\.-?\d+)?$/ 79 // {x..y[..incr]} 80 ``` 81 82 An alphabetic sequence from `x` to `y` inclusive, with optional increment. 83 `x` and `y` must be exactly one character, and if given, `incr` must be a 84 number. 85 86 For compatibility reasons, the string `${` is not eligible for brace expansion. 87 88 ## Installation 89 90 With [npm](https://npmjs.org) do: 91 92 ```bash 93 npm install brace-expansion 94 ``` 95 96 ## Contributors 97 98 - [Julian Gruber](https://github.com/juliangruber) 99 - [Isaac Z.
