What: cpptcl Where: http://www.fas.harvard.edu/%7Edarley/EvoXandCpptcl.html http://www.santafe.edu/%7Evince/pub/cpptcl.tar.gz ftp://ftp.procplace.com/pub/tcl/sorted/packages-8.0/devel/cpptcl2.0.tar.gz ftp://ftp.procplace.com/pub/tcl/sorted/packages-8.0/devel/cpptcl-src.tar.gz Description: Pair of loadable Tcl extensions which work under Unix, Windows, and Macintosh (and possibly others). They are written in C++. They provide tools to allow simple integration of C++ objects with Tcl and its extensions. With cpptcl, you can write C++ classes which smoothly link with Tcl. Binary versions for MacOS 8.1 and Windows NT are also available. Updated: 01/1999 Contact: mailto:email@example.com (Vincent Darley)
What: EvoX Where: http://www.fas.harvard.edu/%7Edarley/EvoXandCpptcl.html Description: An extensible C++ object based simulation system which uses cpptcl. It allows very simple connections between C++ objects and Tcl objects. Updated: Contact: mailto:firstname.lastname@example.org (Vincent Darley)Vince adds, for what it's worth, that I haven't touched this cpptcl for 5 years, and only used it a little in the few years before that. It did have some nice features, but these days I've pretty much abandoned C++ in favour of Java. If anyone does want to use my 'cpptcl', the source is still available, and is free for all uses.
The Tcl::Adapter template is a very powerful way to create extensions. There's an Itcl::Adapter template, too, for when you want to create Incr Tcl class extensions. See  for an example.
