split_regex(x:string, pattern:string, [max:int], [reverse:bool]) -> list

x: string

The string to split.

pattern: string

max: int (optional)

The maximum number of splits to perform.

Defaults to 0, meaning no limit.

Defaults to false.

Examples

Split a string using a regex pattern

from {xs: split_regex("a1b2c", r"\d")}

{xs: ["a", "b", "c", ""]}

from {xs: split_regex("a1b2c3", r"\d", max=1)}

{xs: ["a", "b2c3"]}
