The GenericPretty package

[Tags: bsd3, library]

GenericPretty is a haskell library that provides support for automatic derivation of pretty printing functions on user defined data types. The Pretty library is used underneath, the work is done over Pretty.Doc types.

The output provided by the library functions is identical to that of, except it has extra whitespace.

This requires the use of the new GHC.Generics features: As of 9.08.2011, these aren't present in the stable GHC releases, but seem to be present in the GHC HEAD development snapshots >= 7.1.20110601.

The Generics used are based on those described in the paper A Generic Deriving Mechanism for Haskell : . The changes from the original paper on the ghc implementation are described here:
