Functions

regex.is_match(pattern: String, text: String) -> Bool

Returns true if the regex pattern matches anywhere within the input text.

regex.find(pattern: String, text: String) -> String

Returns the first substring matching the pattern, or an empty string if no match is found.

const token = regex.find("v[0-9]+\\.[0-9]+", "Current release is v2.3.0")

regex.find_all(pattern: String, text: String) -> Vec[String]

Returns all non-overlapping matches as a vector of strings.

const numbers = regex.find_all("[0-9]+", "item1, item2, item3")

regex.replace(pattern: String, text: String, replacement: String) -> String

Replaces all occurrences of the pattern with the specified replacement string.

const sanitized = regex.replace("\\s+", "hello    world", " ")

regex.split(pattern: String, text: String) -> Vec[String]

Splits a string by matching regular expression delimiters.
