  • TclOO 0.1 Released

    Tool Command Language (Tcl) is an interpreted language and very portable interpreter for that language. Tcl is embeddable and extensible, and has been widely used since its creation in 1988 by John Ousterhout. See http://www.tcl.tk/ for more info.


    Donal Fellows is pleased to announce the release of version 0.1 of the TclOO package. This package (which requires Tcl 8.5b1 to work) provides an advanced high-speed Object Oriented system core for the Tcl programming language. It is based on the specification outlined at:
