module SubText : CamomileLibrary.SubText.Type with type ur_text = text and type ur_index = index

Compile regular expressions.

val regexp_match : ?⁠sem:CamomileLibrary.URe.match_semantics -> compiled_regexp -> text -> index -> SubText.t option array option

regexp_match ?sem r t i tries matching r and substrings of t beginning from i. If match successes, Some g is returned where g is the array containing the matched string of n-th group in the n-element. The matched string of the whole r is stored in the 0-th element. If matching fails, None is returned.

val string_match : compiled_regexp -> text -> index -> bool

string_match r t i tests whether r can match a substring of t beginning from i.

val search_forward : ?⁠sem:CamomileLibrary.URe.match_semantics -> compiled_regexp -> text -> index -> SubText.t option array option

search_forward ?sem r t i searches a substring of t matching r from i. The returned value is similar to URe.Type.regexp_match.
