@hackage RepLib0.5.3.3

Generic programming library with representation types

-- Maintainer : sweirich@cis.upenn.edu, byorgey@cis.upenn.edu -- Stability : experimental -- Portability : non-portable

-- RepLib -- a library of derivable type classes based on representation types

-- See http://code.google.com/p/replib/ for more information.

RepLib has been tested with GHC 7.0.1. It currently does not compile with GHC 6.12.x or earlier.

This library contains the following modules:

Generics.RepLib.R - Basic type representations Generics.RepLib.R1 - Parameterized type representations Generics.RepLib.Derive - Template Haskell code to automatically derive representations of datatypes. Generics.RepLib.PreludeReps - Reps of Prelude types Generics.RepLib.RepAux - Helper functions to define type-indexed functions

Generics.RepLib.Lib - Examples of specializable type-indexed functions Generics.RepLib.PreludeLib - Examples type-indexed functions from prelude

Generics.RepLib.SYB.Aliases - SYB: Port of Data.Generics.Aliases Generics.RepLib.SYB.Schemes - SYB: Port of Data.Generics.Schemes

RepLib - Top-level module that re-exports all of the above

To use this library, import RepLib and derive representations of your datatypes. The "Lib" module contains a number of type-indexed operations that have been predefined. To see an example of automatically deriving the representation of a datatype, see the file Main.hs.

Currently, the representations of datatypes with record components, GADTs and nested datatypes cannot be automatically derived.
