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.

defaultStyle :: Style Source #

The default rendering style used in Cabal for console output. It has a fixed page width and adds line breaks automatically.

display :: Text a => a -> String Source #

Pretty-prints with the default style.

flatStyle :: Style Source #

A style for rendering all on one line.

stdParse :: Text ver => (ver -> String -> res) -> ReadP r res Source #
