Open Source Parser Generators

Ayauhteotl is a parser generator to parse XML files, using an XML-like syntax. The parser generator takes an XML file which describe the structure of the XML files to parse and which associates a semantic (for now in \\\\\\\"C\\\\\\\") t

BNF for Java is a BNF Compiler-Compiler, or Parser-Generator. It implements ISO Standard Backus-Naur Format, using Java. BNF allows you to create a syntax, or a complete language, to parse your data source. Your custom Java extensions generate output.

Blade Language Developer (or Project Blade for short) is a toolkit for creating domain specific or general programming languages. The toolkit offers a language for describing grammars, and templatable parser generator.

Generate a parser at runtime from a collection of C++ objects. Concisely state a parser specification in ordinary C++ code. Learn from a parser generator with an object-oriented design.

RiDL is a set of tools to simplify building compilers using Nemerle. It includes a lexical analyzer generator and a parser generator.

Open source mini Python compiler written in Java using Sablecc as parser generator.

It is basically an education Java compiler we are developing - just to gain an insight into the workings of a compiler. It is NOT meant for commercial use!! Its written in Java and uses ANTLR parser generator and the Byte Code Engineering Library extensiv

This project aims to provide a Java-Bytecode compiler for the fairly new programming language WRL and others like PHP4 and Postfix, based on the research on the SableCC parser generator and common W3C.ORG standards.

lightJacc is a small but strong grammar parser generator. It adopts a parsing strategy of its own: dynamic concurrent parsing -- which made it much stronger than LR or LL family CCs (YACC, ANTLR, etc), but still keep good performance.

A parser generator based on parsing expression grammar rules. It generates code and accepts actions in LLVM Assembly rather than C like its predecessor, PEG, did.

The goal of this project is to create a simple and easy to use parser generator that will accept a textual grammar file as an input and output modularized classes representing a limited parser interface. Long term goals include a robust grammar file syntax, output suitable for multiple programming languages, and tools for better integrating compiler functionality, parse tree manipulation, and FSM based scanner generation.

Tedir is a general purpose top-down parser library for java. Unlike a parser generator, it allows efficient parsers to be constructed at run-time, rather than at compile-time, and allows parsers to be extended while running.

A backtracking (non-packrat) parser generator for parsing expression grammars. The parsers are generated at run-time using the LLVM JIT compilation engine.

XMLpg - XML parser generator. Generates an XML parser in C++ from a DTD. The generated code will provide validation as well as conversion of the input XML.

This project is a parser generator, like the lex and yacc, but is based on the JavaCC grammar. It was writing in c++, run on linux and dos, and don't use another library. The grammar parser is specified through a simple file, and the parser generated

A program for generating C++ code based on an RDF schema. The generated code can then navigate RDF structures that conform to the schema.

Pgj is a parser generator written in Java. It generates a paser code for some programming language according to a template.
