val compile : regexp -> compiled_regexpCompile regular expressions.
val regexp_match :
?sem:URe.match_semantics ->
compiled_regexp ->
text ->
index ->
SubText.t option array optionregexp_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 -> boolstring_match r t i tests whether r can match a substring of t beginning from i.
val search_forward :
?sem:URe.match_semantics ->
compiled_regexp ->
text ->
index ->
SubText.t option array optionsearch_forward ?sem r t i searches a substring of t matching r from i. The returned value is similar to URe.Type.regexp_match.
