alex :: IsRegex re s => [(re, Match s -> Maybe t)] -> t -> s -> [t] Source #
a simple regex-based scanner interpretter for prototyping scanners
alex' :: Replace s => (re -> s -> Match s) -> [(re, Match s -> Maybe t)] -> t -> s -> [t] Source #
a higher order version of alex parameterised over the matchOnce
function
IsRegex
class Replace s => IsRegex re s where Source #
the IsRegex class allows polymorhic tools to be written that
will work with a variety of regex back ends and text types
Minimal complete definition
matchOnce, matchMany, makeRegexWith, makeSearchReplaceWith, regexSource
Methods
matchOnce :: re -> s -> Match s Source #
finding the first match
matchMany :: re -> s -> Matches s Source #
finding all matches
makeRegex :: (Functor m, Monad m) => s -> m re Source #
compiling an RE, failing if the RE is not well formed
makeRegexWith :: (Functor m, Monad m) => SimpleREOptions -> s -> m re Source #
comiling an RE, specifying the SimpleREOptions
makeSearchReplace :: (Functor m, Monad m, IsRegex re s) => s -> s -> m (SearchReplace re s) Source #
compiling a SearchReplace template from the RE text and the template Text, failing if they are not well formed
makeSearchReplaceWith :: (Functor m, Monad m, IsRegex re s) => SimpleREOptions -> s -> s -> m (SearchReplace re s) Source #
compiling a SearchReplace template specifing the SimpleREOptions for the RE
makeEscaped :: (Functor m, Monad m) => (s -> s) -> s -> m re Source #
incorporate an escaped string into a compiled RE with the default options
makeEscapedWith :: (Functor m, Monad m) => SimpleREOptions -> (s -> s) -> s -> m re Source #
incorporate an escaped string into a compiled RE with the specified SimpleREOptions
regexSource :: re -> s Source #
extract the text of the RE from the RE
