Description

This modules provides RegexMaker and RegexLike instances for using String with the TDFA backend.

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

Synopsis

Types

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

type MatchOffset = Int #

type MatchLength = Int #

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.

Instances

Show CompOption #
Methods showsPrec :: Int -> CompOption -> ShowS # show :: CompOption -> String # showList :: [CompOption] -> ShowS #
RegexOptions Regex CompOption ExecOption #
Methods blankCompOpt :: CompOption blankExecOpt :: ExecOption defaultCompOpt :: CompOption defaultExecOpt :: ExecOption setExecOpts :: ExecOption -> Regex -> Regex getExecOpts :: Regex -> ExecOption

data ExecOption #

Instances

Read ExecOption #

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

Medium level API functions

compile #

Arguments

:: CompOption	Flags (summed together)
-> ExecOption	Flags (summed together)
-> String	The regular expression to compile (ASCII only, no null bytes)
-> Either String Regex	Returns: the compiled regular expression

execute #

Arguments

:: Regex	Compiled regular expression
-> String	String to match against
-> Either String (Maybe MatchArray)

regexec #

Arguments

:: Regex	Compiled regular expression
-> String	String to match against
-> Either String (Maybe (String, String, String, [String]))
