Cabal-1.8.0.4: A framework for packaging Haskell software Source code Contents Index

Distribution.Text Portability portable Maintainer cabal-devel@haskell.org

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.
