Regular expressions on ropes

#
type t

Type of compiled regular expressions.

#
type match_result = (Zed_rope.Zip.t * Zed_rope.Zip.t) option array option

Type of a match result. If the match fail, None is returned. Otherwise an array of matched sub-strings is returned, the index 0 corresponding to the full match, and other indexes to matched groups.

#
val compile : CamomileLibrary.URe.regexp -> t

compile regexp compiles the given regular expression.

#
val regexp_match : ?sem:CamomileLibrary.URe.match_semantics -> t -> Zed_rope.t -> int -> match_result

regexp_match ?sem regexp rope pos tries to match regexp on given rope, starting at pos.

#
val search_forward : ?sem:CamomileLibrary.URe.match_semantics -> t -> Zed_rope.t -> int -> match_result

search_forward ?sem regexp rope pos searches the given regular expression in rope starting at pos.

#
val search_backward : ?sem:CamomileLibrary.URe.match_semantics -> t -> Zed_rope.t -> int -> match_result

search_backward ?sem regexp rope pos searches the given regular expression in rope starting at pos, in reverse order.
