Welcome to the Wiki of the ParMaLy project.

ParMaLy, short for Parser Grammar Analyzer, is a tool to analyze and improve context-free grammar based on different techniques and parsers. This software does not replace tools like Bison/YACC however, due to the fact that it has no real Code Generator included. You are free to use the generated tables and build your own parser. Remember: Best way to learn something is to implement it on your own.
