A PGroup returned always has (Maybe set to GroupIndex)(Just _)
and never to Nothing.
Synopsis
- parseRegex :: String -> Either ParseError (Pattern, (GroupIndex, DoPa))
Documentation
parseRegex :: String -> Either ParseError (Pattern, (GroupIndex, DoPa)) Source #
Return either an error message or a tuple of the Pattern and the
largest group index and the largest DoPa index (both have smallest
index of 1). Since the regular expression is supplied as [Char] it
automatically supports unicode and \NUL characters.
