Irony is a development kit for implementing languages on .NET platform. 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.

Download contents
The download zip contains core Irony libraries implementing a parsing engine, an interpreter, a number of sample grammars, unit test projects, and Grammar Explorer tool for viewing and debugging your languages (see picture below).
We provide multiple sample grammars for languages like GW Basic, Java, c#, Scheme, SQL, JSON and some others. Irony includes a ready-to-use expression evaluator that can be easily plugged-in into a .NET application.
