Open Source Yacc Software Development Software

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.

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.

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.

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

xuni is a Graphical User Interface widget toolkit, written in C and currently using the SDL. It is very portable and flexible. xuni supports many features including widget rescaling, XML resource files, and loading code dynamically from shared libraries.

xacc.ide is a opensource IDE aimed at mainly .NET development. It has a code editor written in 100% C# code, which is faster than most commercial offerings.

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.

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), ....

A re-implementation of the LISP-like 'Installer' scripting language included with AmigaOS as of version 2.1. InstallerLG aims to be fully compatible with the original as described in the V43.3 documentation. Most of the resource related limitations of the Commodore implementation are gone and the GUI has been replaced by a MUI / Zune based one.

RANGE: produce random genetic transcription networks in the NEMO language, which when compiled outputs models in Systems Biology Markup Language. Generate synthetic microarray data, or use NEMO alone to SBML-ize a network, or visualize it in cytoscape.

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.

ONSlaught is an ONScripter clone with Unicode support and other features. Its aim is to completely replace ONScripter as an open source visual novel engine by providing a completely new design and new features.

freejava is a bundle of tools for programming java easier and faster!

JSEXT is a framework for JavaScript for server scripts, web servers and web clients. Seamlessly integrates C libraries with JavaScript code. Based on this, JSEXT provides support for fastcgi, MySQL, SQLite, FTP, SMTP, HTTP and more.

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.

The LEO-SYSGEN project deals with development of the Sysgen tool for Linux Based ECOS interface for OSEK/VDX Based RTOS. Feel free to download-develop-submit and query about it!!!

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.

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.

The Z83 C Compiler is an optimizing cross compiler for a language very similar to C targeted toward the TI83+. The output from the compiler may be assembled with TASM (http://home.comcast.net/~tasm/) or ZASM (http://lpg.ticalc.org/prj_zasm/).

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.
