    libthreadar

    C++ library to manage threads and any type of exception between them

    Libthreadar is a C++ library providing an abstracted set of C++ *classes* to manipulate threads in a very simple and efficient way from your C++ code. It also handles exceptions thrown from a thread and propagated to another one, when the later is calling the thread::join() method. This let one manage exceptions as simply as it is in C++ single threaded context. Additionally, all the related objects around multi-threading (mutex, semaphore, ...) are provided, under easy to use and independent C++ classes. Other more advanced classes ease the information exchange between threads like scattering and gathering a collection of objects between many threads, or asynchonous buffered information exchanges between two threads. All these C++ classes are easy to use and fully documented

    Space3d

    Space3d

    C# graphics library used for 3D modeling, built with OpenGL/OpenTK

    The Graphics Library is built on top of OpenTK, the C# library that wraps OpenGL. The intended clients are technical and engineering graphics applications that require three-dimensional visualization tool. The implementation draws a scene on separate working thread, optionally, the thread-updater may be invoked. The Space3d Library uses Recursive Composition design pattern. The hierarchy by reference, built into the component, plays a dual role in modeling three-dimensional space: first, it provides a control over a lifetime of the object cluster; second, it mirrors a subordination of the object coordinate systems. All the project libraries are built with Visual Studio, .NET Framework 4.7.1. The Graphics.sln and Space3d.sln solutions contain test applications, called UnitTest, featuring the library capabilities.

    eBus

    Publish/Subscribe, Request/Reply Messaging API for Java.

    A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

    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.
