54 ### var expanded = expand(str)
56 Return an array of all possible and valid expansions of `str`. If none are
57 found, `[str]` is returned.
66 A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
69 /^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
73 A numeric sequence from `x` to `y` inclusive, with optional increment.
74 If `x` or `y` start with a leading `0`, all the numbers will be padded
75 to have equal length. Negative numbers and backwards iteration work too.
78 /^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
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
86 For compatibility reasons, the string `${` is not eligible for brace expansion.
