Open Source C Parser Generators for BSD

Hyacc is an efficient and practical Yacc/Bison-compatible full LR(1)/LALR(1)/LR(0) and partial LR(k) parser generator in ANSI C based on Knuth and Pager's LR(1) algorithms. Generated parser can be used in open-source or commercial software.

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

This project has moved to https://github.com/jplevyak/dparser The master on github is the stable. Please pull that for the very latest code. DParser is a scannerless GLR parser generator based on the Tomita algorithm. It is self-hosted and very easy to use. Grammars are written in a natural style of EBNF and regular expressions and support both speculative and final actions.

The Embedded XML Parser Generator is creating some C source code that parses XML files (or streams) from a user specified document structure. Generated code can support advanced features (inter-dependencies, native data types etc...).

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.

A full LR(1) parser generator system with many advanced features.

Parse software messages and transform them into actions. LazyBat has a command line utility which can transform input data, and also a parser generator for C/C++. LazyBat doesn't support recursive parsing, but rather focuses on common parsing jobs.

PackCC is a packrat parser generator for C, which can handle PEGs (Parsing Expression Grammars) very efficiently, and can support direct and indirect left-recursive grammar rules.

A collection of tools for the SETL Programming Language, including a LALR parser generator and lexical scanner generator.

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.

The purpose of the project was to serve as a testbed for compiler technology. Currently there is a PEG parser generator and a C99 preprocessor in C.

UML 2 Statemachine Code Generator is a developer framework for an easy implementation of statemachine based applications. Here, with this framework only one Domain-specific language (DSL) specification is necessary to create executable codes for Linux, Mac OS X, and Microsoft Windows. With this framework you save a lot of time and effort during implementation; also you have an always valid - based on a well-defined C++ standard - generated code with high quality.

UniCC (UNIversal Compiler-Compiler) compiles an augmented grammar definition into a program source code that parses the described grammar. Because UniCC is intended to be target-language independent, it can be configured via template definition files to emit parsers in almost any programming language. UniCC comes with out of the box support for the programming languages C, C++, Python (both 2.x and 3.x) and JavaScript. Parsers can also be generated into JSON and XML.

Waxeye is a parser generator based on parsing expression grammars (PEGs). It supports C, Java, Javascript, Python, Ruby and Scheme.

C++ parser generator based on project lemon

XML C Parser Generator (xmlcpg) is a xml processor coupled with a flex/bison C parser generator. A DTD can be processed to build a specialized parser for the grammar.
