inline fun CharSequence.replace(regex: Regex, replacement: String): String

Returns a new string obtained by replacing each substring of this char sequence that matches the given regular expression with the given replacement.

The replacement can consist of any combination of literal text and $-substitutions. To treat the replacement string literally escape it with the kotlin.text.Regex.Companion.escapeReplacement method.

Common

inline fun CharSequence.replace(regex: Regex, noinline transform: (MatchResult) -> CharSequence): String
