Text.Regex.TDFA.ByteString
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.
- data Regex
- data CompOption
- data ExecOption
- compile :: CompOption -> ExecOption -> ByteString -> Either String Regex
- execute :: Regex -> ByteString -> Either String (Maybe MatchArray)
- regexec :: Regex -> ByteString -> Either String (Maybe (ByteString, ByteString, ByteString, [ByteString]))

Instances
data CompOption Source
Control whether the pattern is multiline or case-sensitive like Text.Regex and whether to capture the subgroups (1, 2, etc). Controls enabling extra anchor syntax.
