The CDL3 Project

The CDL3 project at the Radboud University Nijmegen in the Netherlands is a framework for research in implementation languages and compiler construction. CDL3 is a programming language, based on Affix Grammars, intended for the development of compilers and other complicated pieces of software that can be implemented as syntax-directed transducers.

Some publications about CDL3:

Superficially, the language looks like PROLOG, a programming language based on a related grammatical formalism namely Metamorphosis Grammars, from which it distinguishes itself in two important aspects:

For these reasons, efficiency and static checking are much better than in PROLOG. CDL3 is available as a compiler generator on numerous platforms, producing either very efficient assembly code or (less efficient but portable) C code. As a language for the efficient development of reliable and maintainable compilers and transducers, CLD3 provides an interesting and efficient way to generate C programs.

The CDL3 system has been developed by Jean Beney, Kees Koster and Paul Jones at the Radboud University Nijmegen. It is freely available under the GPL.
