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.

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? |

search_all(string, string) -> [regex::Match] |
— | Every non-overlapping match, in order. |
