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.

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

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), ....

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.

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

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.

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 interpreter for the Right-reference Pedagogic Algorithmic Language.

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.

March 2013 this project was announced first to public, but the feedback was ZERO. So I guess it is insanely bad and unusable. Ok. But sorry, I decided to continue it for myself to improve my inability and unexperience in software development FOR MYSELF. Even if it seemed to be the worst thing ever, I *NEED* to develop software for my own well being and even if I apparently - after over 20 years since the first lines of code I wrote - I improved my ability not a single bit than it is like that and I can't change it. BTW: there was feedback indeed: from the own 'family': "it is done by YOU so it cannot be of use for anybody!" (Literally: it contains algorithms and algorithms are evil and are non-existent in usable software)

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.

"tikC" is a C compiler driver for GNU/Linux.The initial release version will implement limited C language constructs and with time will grow into a full fledged C compiler driver with an IDE.

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.

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.
