Extensible and Modular Generics for the Masses

Extensible and Modular Generics for the Masses (EMGM) is a library for generic programming in Haskell.

Features

The primary features of EMGM include:

• Datatype-generic programming using sum-of-product views
• Large collection of ready-to-use generic functions
• Included support for standard datatypes: lists, Maybe, tuples
• Easy to add support for new datatypes
• Type classes make writing new functions straightforward in a structurally inductive style
• Generic functions are extensible with ad-hoc cases for arbitrary datatypes
• Good performance of generic functions

The features of this distribution include:

• The API is thoroughly documented with Haddock
• Fully tested with QuickCheck and HUnit
• Program coverage ensures that all useful code has been touched by tests

Examples

You can find examples of using EMGM in the examples directory of the source distribution.
