Description

This defines a Text class which is a bit like the Read and Show classes. The difference is that is uses a modern pretty printer and parser system and the format is not expected to be Haskell concrete syntax but rather the external human readable representation used by Cabal.

Synopsis

class Text a where
defaultStyle :: Style
display :: Text a => a -> String
flatStyle :: Style
simpleParse :: Text a => String -> Maybe a
stdParse :: Text ver => (ver -> String -> res) -> ReadP r res
