regex

Regular expressions, the regex-lite dialect: no look-around or back-references. A pattern is compiled on every call; a match is #{ start, end, text, groups } 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(text: string) -> string	—	text with every metacharacter escaped, so it matches itself.
matches(pattern: string, text: string) -> bool	—	Whether the pattern matches anywhere in text.
replace(pattern: string, text: string, with: string, all: bool?) -> string	—	text with the first match replaced, or every match when all is true; $1 and ${name} in with stand for groups.
search(pattern: string, text: string) -> table?	—	The first match, or nil.
search_all(pattern: string, text: string) -> [table]	—	Every non-overlapping match, in order.
split(pattern: string, text: string) -> [string]	—	The pieces of text between matches.
