    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.
