Nyu is a PEG based parsergenerator in which an appropriate AST type and a parser which populates this AST can be created from a single grammar description.
The Chilon Library is a C++0x utility library. The most advanced parts are a command-line argument parser and a parsergenerator library based on parsing expression grammars with built in AST generation abilities.
Javatools that any Java project will find useful. Highlights are a Rogue Wave DBTools.h++ lookalike that makes RDBMS access easy. It includes an SQL parser and generator. An implementation of Cron and Crontab in java. File logging and assert classes.
Extension of the CUP parsergenerator for working with abstract syntax trees (ast). Implements support for class hierarchy generation and automatic tree building from CUP grammar specification files. Version 10k of CUP is used.
Lemon++ is clone of the Lemon LALR parsergenerator, written by Dr. Richard Hipp ( http://www.hwaci.com/sw/lemon/ ). It adds support for C++, for example user is not limited to POD types.
QPG is a lexer and parsergenerator 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.
A parsergenerator based on parsing expression grammar rules. It generates code and accepts actions in LLVM Assembly rather than C like its predecessor, PEG, did.
XMLGear is an XML parser, styler, generator and editor libruary for Java ME, SE, EE devices. It provides you DOM model support and full object-oriented editor with fast and lightweight code.
A universal parsing tool and source code generator for generative programming. It extracts useful information by parsing (BNF parsergenerator) and generates source code by several techniques, by interpreting a scripting language for flexibility.
Generate a parser at runtime from a collection of C++ objects. Concisely state a parser specification in ordinary C++ code. Learn from a parsergenerator with an object-oriented design.
XML Simple Parser is a parser and generator for xml files which is kept as easy and lightweight as possible. Its intended for use in games or other applications to store data in xml files and for sure also for reading it from there.
lightJacc is a small but strong grammar parsergenerator. 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.
ParGeL is an LALR(k) parsergenerator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.
Complete LALR(1) parsergenerator and engine in PHP.
Complete LALR(1) parsergenerator and engine (like BISON or YACC) but it's all done in PHP, and the input grammar is easier and more maintainable. Write your actions in PHP. Generate PHP output code. Drive your parser with PHP. Wanna make a language?
OFD.NET is a project to create an Open Flash Debugger in C#, plus other tools targeting flash technology and especially actionScript. There are plans for a swf parser/generator, an AS3 compiler, a decompiler, etc.
CSP Canonical LR(1) ParserGenerator. Includes lexer and parsergenerator. Supports all OS. Produces code as standard ANSI C++ w/ minimal STL and usable in commercial or non-commercial purposes.
Annotation based lexer and parsergenerator suitable for processing wide range of languages, from small domain specific languages to big ones like Java. Actions may be written directly as annotated java methods. Examples of expression language and Java5.
More Than Parsing is a parsergenerator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
Covra is a project to help design compilers. C3 is a tool specialized on the easy design and construction of ASTs, it is independent of the compiler compilers or parsergenerator that is used. It generates Java and C# code. Require JRE 1.6.0.
Linear time, dynamic API for lexical analysis and parser generation. Allows for a text-based specification of formal languages with the well-known regular-expressions approach, and using Parsing Expression Grammars as the underlying engine.
