Description

This defines a Text class which is a bit like the Read and Show classes. The difference is that it 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

Documentation

class Text a where #

Note: this class will soon be deprecated. It's not yet, so that we are -Wall clean.
