Functions

Regular expressions, the regex-lite dialect: no look-around or back-references. A pattern is compiled on every call; a match is a Match, with byte offsets and one string per capture group, nil for a group that took no part.

6 functions, 0 constants. Scripts reach it as regex::.

Functions

Argument kinds are the script values a call passes: node is a node handle, any a table or value of any kind, fn a callback.

function	acts on	what it does
`escape(string) -> string`	—	`text` with every metacharacter escaped, so it matches itself.
`matches(string, string) -> bool`	—	Whether the pattern matches anywhere in `text`.
`replace(string, string, string, bool?) -> string`	—	`text` with the first match replaced, or every match when `all` is true; `$1` and `${name}` in `with` stand for groups.
`search(string, string) -> regex::Match?`	—	The first match, or nil.
`search_all(string, string) -> [regex::Match]`	—	Every non-overlapping match, in order.
`split(string, string) -> [str]`	—	The pieces of `text` between matches.
