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.
Java GetOpt Generator is a tool that generates a command-line argument parser from an XML file. Both a "parser" and "config" class are generated, which allows your program to either be launched from the command-line or programmatically configured and executed from another Java application. GetOpt Generator is self-hosting, meaning that it uses itself to generate its command-line parser.
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).
This software adds Octave support to SWIG. Octave code can use C/C++ functions, variables, constants and enums, classes (member variables, methods, single/multiple inheritance, etc), and templates. Argument/result translation is completely extensible via %typemap and other declarations in interface files. Octave operators map to C++ operators, methods, or global functions. Octave code can subclass C++ types and implement their virtual methods (i.e., C++ code transparently calls Octave code). There is some support for STL containers. There are many automated tests and examples.
Pork.Generator is a Web based tool to inspect your databases and generate Pork.dbObject based code. The generator analyzes the relations in your database by trying to match primary keys to fields of other tables. If you have created your table structure following some simple rules, this project can either create a complete CRUD (Create, Read, Update, Delete) interface into a .zip file, or just output your complete database schema into O/R mapped objects. Pork.dbObject is an Object-Relation mapper for PHP 5 that attempts to be easy, fast, and lightweight.
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.
