Parser Generator

Dragon is a powerful parser generator. It produces a consequent, object-oriented, integrated scanner and parser solution. Dragon parser generator also scales for very large grammar defintions. Since dragon parses LR(1) grammars, the generation algorithm is quite CPU intensive. Using LR(1)...

JS/CC is a parser generator for JavaScript/ECMAScript, which is entirely written in ECMAScript itself. It produces LALR(1) parsers with integrated lexical analyzers. JS/CC can run as a website or be invoked from a console, and runs on several platforms.

Complete LALR(1) parser generator 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?

Monkey is a scanner and a LR(1) parser generator for object oriented languages. The platform on wich it runs is Java.


Platforms: Windows, Mac, Linux

ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.

Koopa is a Cobol parser (generator). It can handle source files in isolation (no preprocessing required) and doesn't mind the presence of CICS/SQL fragments. The grammar is easily extensible in a way which minimizes the impact on the overall code.


Platforms: Windows, Mac, Linux

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


Platforms: Windows, Mac, BSD, Linux

Genparse is a command line parser generator. Based on a simple description of the command line options you want in your program, genparse creates the necessary C, C++ or Java code for their processing.

PyBison is a Python binding to the Bison (yacc) and Flex (lex) parser-generator utilities. It allows parsers to be quickly and easily developed as Python class declarations, and for these parsers to take advantage of the fast and powerful C-based Bison/Flex. Users write a subclass of a basic...

Bison project is a general-purpose parser generator that converts a grammar description for an LALR context-free grammar into a C program to parse that grammar. Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk...

LLnextgen is an Extended-LL(1) parser generator. LLnextgen project is a rewrite of the LLgen parser generator by D. Grune and C.J.H. Jacobs which is part of the Amsterdam Compiler Kit (ACK). Like all parser generators, LLnextgen takes the description of the grammar with associated actions as...

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 its C interface which provides access to the abstract syntax tree,...

Berkeley Yacc is an LALR(1) parser generator. Berkeley Yacc has been made as compatible as possible with AT&T Yacc. Berkeley Yacc can accept any input specification that conforms to the AT&T Yacc documentation. Specifications that take advantage of undocumented features of AT&T Yacc will probably...
