regex

The regex module provides regular expression matching, searching, and replacement. Requires import regex.

Function Reference

Function	Signature	Description
is_match	(String, String) -> Bool	Check if pattern matches anywhere in string
full_match	(String, String) -> Bool	Check if pattern matches entire string
find	(String, String) -> Option[String]	Find first match
find_all	(String, String) -> List[String]	Find all non-overlapping matches
replace	(String, String, String) -> String	Replace all matches
replace_first	(String, String, String) -> String	Replace first match
split	(String, String) -> List[String]	Split by regex pattern
captures	(String, String) -> Option[List[String]]	Extract capture groups from first match

Note: The first argument is always the regex pattern, the second is the string to search.

Examples

import regex

regex.is_match("[0-9]+", "abc123")              // => true
regex.full_match("[0-9]+", "123")               // => true
regex.find("[0-9]+", "abc123def")               // => some("123")
regex.find_all("[0-9]+", "a1b2c3")              // => ["1", "2", "3"]
regex.replace("[0-9]+", "a1b2", "X")            // => "aXbX"
regex.replace_first("[0-9]+", "a1b2", "X")      // => "aXb2"
regex.split("[,;]", "a,b;c")                    // => ["a", "b", "c"]
regex.captures("(\\w+)@(\\w+)", "user@host")    // => some(["user@host", "user", "host"])
