GCC for SPARC Systems extends GCC to be able to use the optimizing Sun Code Generator for SPARC systems. The compiler commands are the same as GCC. All of the GCC command-line options are available. Programs compiled with GCC for SPARC Systems follow the same ABI as programs compiled by GCC. You can mix and match objects compiled with GCC for SPARC Systems and objects compiled with GCC.
Cobra is a general purpose programming language with a clean, high-level syntax. It provides language level features for quality, including first class unit tests and Eiffel-style contracts. It supports both static and dynamic binding. Cobra is a compiled language with good run-time performance, but also provides some scripting conveniences such as a pound-bang line (#!) and one step compile-and-run. Cobra runs on Linux, Mac, Windows, and anywhere else that Novell Mono or MS .NET exist, including handhelds.
FrobTADS is a complete rewrite of the Unix console-version of TADS ("Text Adventure Development System"). It uses curses (or ncurses) and provides an interpreter to play games developed with TADS as well as the TADS 2 and 3 development tools. It adds support for a number of relatively recent user interface features including full support for text and background colors, TADS 3 banner windows, and timed input. It's also much more portable and more easily maintainable, as it's built to modern Unix standards.
The Abacus Formula Compiler (AFC) compiles computations defined in spreadsheet files directly to Java byte code. Users can thus customize an application using Excel or OpenOffice Calc. AFC compiles against your own Java interfaces to obtain input values and compute output values (it essentially generates strategy implementations for you), and supports internal computations with either double or BigDecimal (for financial applications).
Faust AUdio STreams is an expressive functional programming language for realtime audio signal processing. The Faust compiler translates DSP specifications into efficient C++ code. A variety of platforms and plugin formats are supported. A single Faust specification can be used to easily generate JACK and ALSA applications, as well as LADSPA, MAX/MSP, PD, Q, SC, and VST plugins. In addition to C++ code, the Faust compiler can also generate SVG block-diagram representations as well as XML descriptions.
gtkaml is an XML syntax and parser that extends the Vala.Parser and transforms all your tags into a valid Gtk+ UI class. It features a casual XML syntax for describing the way Gtk widgets are laid out in a (new) custom widget you're creating. Code "islands" (written in Vala) are used for widget signal handling and other methods/signals/properties that you're introducing. It doesn't depend on an external library at run-time, and it is much more readable than the usual UI boilerplate.
