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

-- See http://www.cis.upenn.edu/~sweirich/RepLib for more information.

RepLib has been tested with GHC 6.8.3 and 6.10.3.

This library contains the following modules:

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

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

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

RepLib - Toplevel module that imports 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.
