Wisent is an LALR(1) parser generator with pluggable front- and backends. It generates object-oriented code with clean namespace separation. A yacc-like frontend is currently accompanied by a C++ and a Java backend. The tool itself is implemented in C++.
In a nutshell it takes as input the formal specification of any text protocol in ABNF and generates the parser in C language for that grammar using lex/yacc.
Many Tools: PHP-based context-free grammar (CFG) parser generator, simple scanner generator, and nascent object relational mapping/query language in PHP. Talks to Postgres, MySQL for now. Needs PHP5. Comes with (relies on) many convenience functions.
Not C Sharp. Four goals: 1. Create a CSharp compiler written in C# and CUP Parser Generator. 2. Learn how to write a compiler. 3. Encourage compiler experimentation by anyone who is interested.
