Irony - .NET Compiler Construction Kit.

Irony is a new-generation .NET compiler construction kit. It utilizes the full potential of c# 2.0 and .NET Framework to implement a completely new and streamlined technology of compiler construction.
Unlike most existing yacc/lex-style solutions Irony does not employ any scanner or parser code generation from grammar specifications written in a specialized meta-language. In Irony the target language grammar is coded directly in c# using operator overloading to express grammar constructs. Irony's scanner and parser modules use the grammar encoded as c# class to control the parsing process. See the expression grammar sample for an example of grammar definition in c# class, and using it in a working parser.

Initial Release
The initial release contains implementation of compiler front-end modules - scanner and LALR(1) parser. We provide several test grammars and parser implementations based on them: a grammar for parsing arithmetic expressions, and simplified grammars for Scheme, Python and Ruby.

System Requirements
Windows XP/Vista, .NET Framework 3.5, Visual Studio 2008
