Open Source Yacc Compilers for BSD

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), ....

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.

A strong, yet minimalistic Math-oriented Programming Language (MML) providing an easy-to-use console and a command-line script interpreter, targetted towards fast calculations for extremely big numbers, and bundled with a number of math libraries.

The CCC Language is yet another programming language. It is platform-independent, compact, and robust. Supports many SQL engines, has own ISAM DB engine, has terminal mode and more UI-s, is object-oriented, but it is compiled and not interpreted.

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

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.

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)

‘intelliworm’ is a prototype simulation of a Intelligent Species of a common earth worm,which inherits human like decision making capabilities through Neural Network intelligence representation,all developed by integrating .NET with Lisp and Yacc.

The Ivory Programming Language: A modern language for systems programming

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.

Standard ML of Sønder Tranders.

WebTugaPL - WebTuga Programming Language (Projecto para uma linguagem de programação simples e fácil de aprender e utilizar em português).

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/).

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/

"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.
