Signature

1regexp(find::string, replace::string= ?, input::string= ?, ignorecase::boolean= ?)

Creates an ICU regular expression object.

regexp constructs or identifies a LaiRu value type. regexp uses the regular-expression surface for pattern matching. Keep patterns small, name the intent in nearby code, and test captures separately from replacement strings.

Parameters

find: Required value of type string. Supply find positionally unless the signature shows a keyword form.
replace: Optional value of type string. Supply replace positionally unless the signature shows a keyword form.
input: Optional value of type string. Supply input positionally unless the signature shows a keyword form.
ignorecase: Optional value of type boolean. Supply ignorecase positionally unless the signature shows a keyword form.
