Open Source C++ Parser Generators for BSD

A runtime parser generator library, generates parsers for context-free grammars. Parsing scripting languages and communication protocol messages are typical use cases. The library is written in straight C++ and requires STL. Clean, correct, efficient.

A universal parsing tool and source code generator for generative programming. It extracts useful information by parsing (BNF parser generator) and generates source code by several techniques, by interpreting a scripting language for flexibility.

CppCC is an object-oriented scanner and LL(k) parser generator. It aims to replace LEX&YACC for those who write C++ applications that involve parsing.

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.

CSP Canonical LR(1) Parser Generator. Includes lexer and parser generator. Supports all OS. Produces code as standard ANSI C++ w/ minimal STL and usable in commercial or non-commercial purposes.

C++ LALR parser generator

Lapg is the combined lexical analyzer and parser generator, which converts a description for a context-free LALR grammar into source file to parse the grammar. Generates code for Java, Javascript, C, C++ and C#.

Soul is a recursive descent parser generator tool for Windows and Linux that comes with a parsing library.

Styx is a scanner and parser generator designed to address some shortcomings of the traditional lex/yacc combination. It has unique features like automatic derivation of depth grammar, production of the derivation tree including it's C interface which provides access to the abstract syntax tree, preservation of full source information and pretty printing to facilitate source-source translation, persistence to aid rapid interpreter writing. For application in contemporary computing environments, it supports unicode, reentrancy and offers thread-safeness.

Scannerless recursive descent C++ parser generator

Spirit is an object oriented recursive descent parser generator framework implemented using template meta-programming techniques.

Wisent is an LALR(1) parser generator with pluggable front- and backends. It generates object-oriented code with clean namespace separation. A yacc-like frontend is currently accompanied by a C++ and a Java backend. The tool itself is implemented in C++.

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

The Chilon Library is a C++0x utility library. The most advanced parts are a command-line argument parser and a parser generator library based on parsing expression grammars with built in AST generation abilities.

Implementation of a combined scanner and parser generator for object oriented C++ or Java code generation

C++ parser generator based on project lemon

QPG is a lexer and parser generator tailored for modern C++. The syntax of its grammer is designed to be more flexible and easily read than those of traditional tools like flex and bison. It's build on Qt4 but can produce output independent of it.
