The BiGUL package

[ Tags: generics, language, lenses, library, public-domain ] [ Propose Tags ]

Putback-based bidirectional programming allows the programmer to write only one putback transformation, from which the unique corresponding forward transformation is derived for free. BiGUL, short for the Bidirectional Generic Update Language, is designed to be a minimalist putback-based bidirectional programming language. BiGUL was originally developed in the dependently typed programming language Agda, and its well-behavedness has been completely formally verified; this package is the Haskell port of BiGUL.
