(* Regular expression matching

This library implements ECMAScript regular expressions. *)

(* Searching *)

(* Matches a regular expression against any part of a string.  Returns 'Some
strs', where 'strs' is a list of subexpression matches, if a match succeeds, and
'None' otherwise. *)
val match : string (* needle *)
         -> string (* haystack *)
         -> option (list string)

(* Replaces all substrings in 'haystack' that match 'needle' with the string
'replacement.' *)
val replace : string (* needle *)
           -> string (* haystack *)
           -> string (* replacement *)
           -> string
