Text.RE.PCRE

Tutorial

We have a regex tutorial at http://tutorial.regex.uk. These API docs are mainly for reference.

The Overloaded Match Operators

(*=~) :: IsRegex RE s => s -> RE -> Matches s

find all matches in text

(?=~) :: IsRegex RE s => s -> RE -> Match s

find first match in text

(=~) :: (RegexContext Regex s a, RegexMaker Regex CompOption ExecOption s) => s -> RE -> a

the regex-base polymorphic match operator

(=~~) :: (Monad m, RegexContext Regex s a, RegexMaker Regex CompOption ExecOption s) => s -> RE -> m a

the regex-base monadic, polymorphic match operator

Beyond the above match operators and the regular expression type below, Text.RE contains the toolkit for replacing captures, specifying options, etc.
