regex

native module

A small backtracking engine (no PCRE). import "regex". Supports . * + ? ^ $, [...]/[^...] classes with ranges, \d \w \s (and \D \W \S), | alternation, and () grouping. No capture extraction, {n,m} counts, or backreferences; matches on bytes. All functions take (pattern, text) first.

regex.match(pattern, text: string) => bool
regex.find(pattern, text: string) => string?
regex.find_all(pattern, text: string) => [string]
regex.replace(pattern, text, replacement: string) => string
regex.split(pattern, text: string) => [string]

regex.match(pattern, text: string) => bool

Does the pattern match the entire text (honoring ^/$).

regex.find(pattern, text: string) => string?

First matching substring, or nil.

regex.find_all(pattern, text: string) => [string]

All non-overlapping matches.

regex.replace(pattern, text, replacement: string) => string

Replace every match with the literal replacement (no $1).

regex.split(pattern, text: string) => [string]
