syb: Scrap Your Boilerplate

[ bsd3, generics, library ] [ Propose Tags ]

This package contains the generics system described in the Scrap Your Boilerplate papers (see http://www.cs.uu.nl/wiki/GenericProgramming/SYB). It defines the Data class of types permitting folding and unfolding of constructor applications, instances of this class for primitive types, and a variety of traversals.

syb: Scrap Your Boilerplate!
================================================================================

Scrap Your Boilerplate (SYB) is a library for generic programming in Haskell. It 
is supported since the GHC >= 6.0 implementation of Haskell. Using this 
approach, you can write generic functions such as traversal schemes (e.g., 
everywhere and everything), as well as generic read, generic show and generic 
equality (i.e., gread, gshow, and geq). This approach is based on just a few 
primitives for type-safe cast and processing constructor applications. 

It was originally developed by Ralf Lämmel and Simon Peyton Jones. Since then,
many people have contributed with research relating to SYB or its applications.
