Coco/R combines the functionality of the well-known UNIX tools lex and yacc, to form an extremely easy to use compiler generator that generates recursive descent parsers, their associated scanners, and (in some versions) a driver program, from attribu...

Port of lex and yacc to Delphi 3. Base at port to Turbo Pascal.

A Flex like scanner code generator, but it generates C++ scanner classes that are re-entrant and compatible with the newer standard of C++/STL. Multiple scanner classes and instances can co-exist in a program without tweaking of macros.

object-oriented grammar definition language and integrated suite of visual tools that assist in building, testing and debugging parsers.

A simple to use translator generator.

An object oriented recursive descent parser generator framework implemented using C++ operator overloading techniques. It is inspired by Spirit, but use only few template classes thus allowing more flexibility and fastest compilation time. [Open sourc...

TPG is a parser generator for Python. Given a simple attributed grammar, TPG produces a Python Recursive Descent Parser. It is simple and useful for small parsers for everyday use.

a scanner+LL(k = 1..Inf) parser generator for C++. Allows easy top-down description of grammars in an intuitive and extensible manner. Good generated code speed (as comared to GNU Flex/Bison). [Open source, GPL]

A runtime parser generator library. It generates parsers from BNF-like language grammars. Parsing scripting languages and communication protocol messages are typical use cases. [Public domain]

The combined lexical analyzer and parser generator, which converts a description for a context-free LALR grammar into source file to parse the grammar. [Open source, GPL]
