Text.Regex.TDFA.ByteString.Lazy

Contents

- Orphan instances

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`.

Synopsis

- 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]))

# Documentation

data Regex #

The TDFA backend specific `Regex` type, used by this module's RegexOptions and RegexMaker

Instances

RegexOptions Regex CompOption ExecOption # |
Methods blankCompOpt :: CompOption # blankExecOpt :: ExecOption # defaultCompOpt :: CompOption # defaultExecOpt :: ExecOption # setExecOpts :: ExecOption -> Regex -> Regex # getExecOpts :: Regex -> ExecOption #

data CompOption #

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.
