    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

    ObjectiveScript

    object orientated scripting language

    == This project has been renamed to slang-lang/slang and moved to Github. == ObjectiveScript is an object orientated scripting language that tries to combine the speed of scripting with an object orientated syntax similar to Java and C++. The language offers native data types like bool, double, float, int and string as well as user defined object types and a system library with data types similar to the Java boxed types like Integer and String. Collections like List, Map, etc. can be used with object and value types and can also be used as raw types (i.e. List == List<Object>).
