Parser library that uses an EBNF like grammar to generate a parse tree You can use it to create a quick parser It uses backtracking so it may be slow for some grammar rules

CodeConics is simple, intuitive, easy to use and debug code-manipulation solution, that is grammar independent and recursion based, as opposed to other DFA(Deterministic Finite-state Automata) based solutions.

NLT is free, open-source C# lexer and GLR parser suite -- which translates to ability to parse ambiguous grammars. Grammar can be defined directly in code or (preferably) in separate file (lex/yacc-like) for included generator. If you understand/guess the meaning of grammar in C#: // scanning lexer.AddStringRule(")", match => SymbolEnum.RPAREN); // parsing prod_builder.AddProduction(SymbolEnum.exp, SymbolEnum.LPAREN, SymbolEnum.exp, SymbolEnum.RPAREN, (_1, e, _3) => (AstNode)e); or grammar in NLT format: // scanning /[A-Za-z_][A-Za-z_0-9]*/ -> IDENTIFIER, IdentifierSymbol.Create($text); // parsing program -> list:namespace_list { new Program(currCoords(), (Namespaces)list) }; you should be able to use it :-). ...

AleSimpleLexer is a C# class that tokenizes given text. Can process lists, numbers, text constants, parentheses and comments. Supports unicode.

A 3D graph explorer for tree-like acyclic graphs. The graph nodes are placed in the 3D space based on their level from the root node so that child nodes make a circle under the parent node. Currently supports Graphviz *.dot format and XML. Have fun!

Php Lexer - converts .lex files into .php files (so you can tokenize files) used to be: a PHP compiler for the .NET CIL (but that's pretty dead now)
