The FormalGrammars package

[Tags: gpl, library, program]

Context-free grammars in formal language theory are sets of production rules, non-terminal and terminal symbols. This library provides basic data types and functions to manipulate such grammars.

Grammars can be defined in a small domain-specific language that is very close to typical CFG notation.

In addition, TemplateHaskell and QuasiQuoting functionality allow embedding thusly defined grammars in Haskell programs. ADPfusion then turns such a grammar into an efficient dynamic program. It is also possible to generate Haskell modules that contain the resulting grammar, signature and algebra product.

Alternatives are ansi- or LaTeX-based pretty-printing for users that want to implement their CFG in another language than Haskell.

Formal background can be found in two papers: Christian Höner zu Siederdissen, Ivo L. Hofacker, and Peter F.
