Open Source Yacc Software Development Software

NOTE! We have moved to https://gitlab.com/msc-generator/msc-generator All development happens there. Also, download new releases & submit issues there. A tool to draw various charts from textual descriptions. Currently, three types of charts are supported: Message Sequence Charts, generic Graphs, and Block Diagrams, with more to be added in the future. There is a command-line version for Linux and Mac (replacing mscgen), which now sports a GUI, as well. Msc-generator allows fine control over the appearance and has a rich feature set complete with detailed documentation. On Windows, you can embed the charts in a document or presentation and simply double-click it in Office to edit them. On Linux and the Mac, a command-line version is available, and a GUI, as well. A .deb package is available starting from Debian Bookworm (currently testing) and Ubuntu Jammy Jellyfish (22.04) from the official repositories. For older releases see the Wiki. A Mac homebrew package is available.

Findent indents, beautifies and relabels Fortran source, fixed and free format, and converts Fortran fixed format to Fortran free format (and vice-versa). Plugins for vim, emacs and gedit are included.

An open source COBOL compiler for the PC x86-32 platform. Generates GNU assembler and requires GCC to produce a binary. Supports Linux, BSD and MinGW 32 bit platforms.

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.

Clipper/XBase compatible compiler with initial support other xBase dialects. Multitasking, OOP,SIX/Comix, SQL and ODBC drivers,a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), ....

Tunguska is a ternary computer emulator. The goal is to provide a relatively easy-to-use platform, reminiscent of an early PC, for people who want to experience and experiment with ternary computing hands-on.

Sieve is a mail filtering language standardized as RFC 3028 / RFC 5228 and its extensions. libSieve provides a simple, clean API for parsing and executing Sieve scripts. Code is on GitHub: http://github.com/sodabrew/libsieve

A parsing toolkit that supports both top-down (LL(1) and Simple Precedence) and bottom-up parsing (LR(0), SLR(1), LR(1) and LALR(1)). The toolkit supports generating Java parsers for all the bottom-up parsing methods, based on a CUP definition.

Mutabor is a Program that allows performing and composing microtonal music using a normal MIDI keybord. But it's powerful description language is intended to allow permanent retunings and tuning logics in to describ, what's actually goes on.

WinTriangle is a specialized RTF word processor capable of displaying and voicing math and science documents.Scientific expression to be expressed in a linear form. The goal is to provide a common format usable by sighted and visually impaired people.

Y2L is a Yacc-to-Latex pretty printer/convertor. It converts Yacc grammar descriptions into EBNF descriptions in LaTeX or plain ASCII. It's written entirely in AWK.

Elice is a free compiler for programs written in the proprietary language PureBasic. It compiles those programs to C++ and then uses g++ to generate an executable. This is an old version. Development has moved to https://gitorious.org/elice/

Given YACC-like and LEX-like input files, yagg generates a C++ program that generates all strings of a user-specified length. yagg is easy to use, and provides a means of generating test inputs or validating a parser grammar by inspecting the strings.

Aquamarine is a Object Oriented language. The goal of this project is to provide a aquamarine to C++ compiler and a classes library.

Simple PHP compiler for a university subject.

Eclipse Plug-in for Bison. Uses the yacc context free programming language to generate compilable C code.

Blackboard implements a lightweight, portable tuple space suitable for multi-agent system and distributed component design. Supports implicit invocation via content-filtered asynchronous events, blocking call semantics, and shared memory messaging.

A three-address code (C3A) compiler, implemented as a new front end to the GCC compiler.

This utility is to construct the interactive function call graph.

CompilerEngine is a compilation engine, you can easily make a quick cross-platform compiler. But CompilerEngine just a preliminary framework for a prototype or preliminary design, there are many imperfections.

A program for syntactically correct sentence generation. Guided by a Bison grammar file as input, it provides random or coverage testing sentences. The program can be used for compiler or parser testing or didactical purposes.

Binutils, gcc, gdb and glibc re-targeted for MIPS R3000R and R5900 as shipped in PlayStation and PlayStation 2 video game consoles, both from Sony Computer Entertainment Inc.

gpint is a General Purpose Interpreter for a Pascal-type language written in the C programming language. It runs interactively and can run scripts. It was designed to be as simple as possible, easy to understand and easily extensible.

Gimp User Filter is a plugin for The Gimp (http://www.gimp.org/), originally written by Jens Restemeier back in 1997. This project is about maintaining the plugin, keeping it compatible with current versions of Gimp, and eventually extending its features

The Green Engine was designed as an introduction to programming and game development for those who have little or no previous experience. The games developed using this system are described in a high level, simple to use scripting language.
