generics-sop: Generic Programming using True Sums of Products

A library to support the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

The module Generics.SOP is the main module of this library and contains more detailed documentation.

Since version 0.4.0.0, this package is now based on sop-core. The core package contains all the functionality of n-ary sums and products, whereas this package provides the datatype-generic programming support on top.

Examples of using this library are provided by the following packages:

• basic-sop basic examples,

• pretty-sop generic pretty printing,

• lens-sop generically computed lenses,

• json-sop generic JSON conversions.

A detailed description of the ideas behind this library is provided by the paper:

• Edsko de Vries and Andres Löh. True Sums of Products. Workshop on Generic Programming (WGP) 2014.
