    EiffelStudio
    EiffelStudio is an Integrated Development Environment (IDE) that provides comprehensive facilities to programmers. It offers a comprehensive suite of tools that enable programmers to produce correct, reliable, and maintainable software while keeping control of the development process. If you want to create fast, robust, scalable applications, then EiffelStudio™ will offer you a cost-effective solution. Imagine being able to model your system as you think – capturing your requirements and your thought processes with EiffelStudio. When ready to design, you build upon the model you just created, still with EiffelStudio. Then you implement with EiffelStudio. You never need to throw anything out and start over. You don’t need extra tools to go back and safely make changes in your architecture. Roundtrip engineering? It’s built in by design. Testing, metrics and productivity tools? They’re built in. EiffelStudio accommodates quickly and efficiently new thoughts and changes.

    JILRuntime/JewelScript

    An object-oriented script language to embed in any application

    A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.

    ctalk

    Object Oriented Language

    IMPORTANT: Please refer to the Ctalk wiki, available from the tab above, for important release information. Ctalk is a compact object oriented language that works closely with C. That means you can use Ctalk for GUI, network, client-server, and systems programs as well as traditional object oriented simulations, with all of the advantages of a true object oriented language, like class and method inheritance, and rapid prototyping. Ctalk includes a just-in-time compiler, a compact run-time library, and a developing set of X widgets and OpenGL classes to create desktop and 3-D modeling apps. Written for use with GNU GCC and LLVM, Ctalk supports a variety of UNIX, Linux, and MacOS systems, the X Window System, and libraries like the GNU readline library, and the Xft Type1, FreeType and TrueType font libraries. To find out what's new in the latest release, check out the ReleaseNotes page of the Ctalk Wiki which is available by clicking on the tab above.

    The Magda language

    Magda language resource site

    Magda is a programming language introduced in Jarek Kusmierek's PhD (http://www.mimuw.edu.pl/~jdk/mixiny.pdf) and continued in Mauro Mulatero's thesis (http://www.tesionline.it/default/tesi.asp?idt=45612). Magda's goal is to allow a programmer to write well-modularized, reusable code. Magda is based upon the core notion of mixin as the only unit of reuse. The power of modularization of mixins is enhanced by two unique features. The first feature is the modularization of constructors. In Magda, many mixins with independent definitions of constructors can be combined without the need to copy any code and without the risk of clashes. The second distinctive feature modifies the way declarations of new methods, overriding methods, and method calls are done, in order to rule out accidental name clashes, even with respect to future modifications of the code. Samples written in Magda language, together with an IDE (by Marco Naddeo), are available in the download.

    Advanced Symbolic Instruction Language

    A 21st century programming language derived from BASIC

    If the words "Symbolic Instruction" in the name sound familiar, they should. ASIL (pronounced "a-sill") was largely inspired by BASIC. However, instead of starting with a modern verison of BASIC, I started with AppleSoft. Why? Well, ASIL was born in the early 1990s while I was in college. I knew AppleSoft quite well as it was my first programming language. ASIL nearly died then as the compiler technology wasn't up to the job. Now, I figure those compilers might be able to do the job. ASIL now incorporates features from C++, C#, modern BASICs, and Java. Yet, if you look at sample code, it clearly isn't any of those. In fact, even though it's "derived from BASIC", it's relationship to modern BASIC dialects like VB is more like a very distant cousin. You might have troubles calling "BASIC" once you see sample code. We have an IRC channel: ircs://irc.freenode.net/asil-language. Those running the ChatZilla IRC client can use ircs://freenode/asil-language instead.
