Text.Regex.TDFA.Sequence

regex-tdfa-1.1.1: Replaces/Enhances Text.Regex

Description

This modules provides RegexMaker and RegexLike instances for using ByteString with the DFA backend (Text.Regex.Lib.WrapDFAEngine and Text.Regex.Lazy.DFAEngineFPS). This module is usually used via import Text.Regex.TDFA.

This exports instances of the high level API and the medium level API of compile,execute, and regexec.

compile

:: CompOption	Flags (summed together)
-> ExecOption	Flags (summed together)
-> Seq Char	The regular expression to compile
-> Either String Regex	Returns: the compiled regular expression

execute

:: Regex	Compiled regular expression
-> Seq Char	ByteString to match against
