QCL is a high-level, architecture-independent programming language for quantum computers, with a syntax derived from classical procedural languages like C or Pascal. This allows for the complete implementation and simulation of quantum algorithms (including classical components) in one consistent and familiar formalism. QCL is especially meant for users with a math/CS rather than a physical background, who want to play with non-classical algorithms.
SHACC (Shaggy's Homebrew Alternative Compiler Compiler) reads an extended yacc-style grammar specification and generates an LR(k) parser for it. The main purpose of SHACC is to be able to parse complex grammars with ambiguities that YACC cannot handle, such as C++ (which it was originally developed for). If your grammar results in lots of shift/reduce and reduce/reduce errors in YACC, and you don't want to rewrite it in ways that make the grammar more complex and hard to understand, you might want to try out SHACC instead.
The Table Driven Assembler (TDASM) is a portable cross assembler for any kind of assembly language. It should be possible to use it as a compiler to any target microprocessor using a table that defines the compilation process. The development of the project has been terminated. Anyone who would like to continue with development is welcomed, but there is only czech documentation available.
The cutils collection is composed of: cdecl and cundecl (decode and encode C type declarations), cobfusc (make a C source file unreadable but compilable), chilight (highlight C source files), cunloop (unloop C loops), yyextract (extract grammar rules from yacc grammar), and yyref (generate a cross-reference for yacc input).
MetaRuby contains miscellaneous libraries (useful now) for a future Ruby-in-Ruby interpreter including Array/Hash/String as abstract ("Hollow") classes, an undo queue, a statistical time-profiler, an event loop, a modular marshaller ("ToSource"), a specification for a modular+reflexive+homoiconic remote call system ("LGRAM"), a declarative type system, a schema for expressing Ruby source code as proper (non-special) Ruby objects, etc.
