Version 1 of itcl-ng

Why do I build itcl-ng?

About September 2006 I apw started to think about the future of incr tcl / Itcl. I had heared that there are a lot of problems in Tcl core because of Itcl. So I was thinking about a new version. The first idea was to build a Tcl only version. The story of that approach can be seen at tclOO missing features for Itcl.

After all I have started with the 4th start using original Itcl source code (because of performance problems with the other projects) and replacing all the dispatching and the code directly working in Tcl core areas with tclOO and a small layer which can perhaps in the future be integrated into Tcl core.

Goals, ideas etc.

  1. to make Itcl easier to maintain with respect to Tcl core (at the moment there are a lot of "hacks" in Tcl core only needed for Itcl)
  2. use tclOO as a dispatcher and to use in the future some of the features available there (filters, mixins)
  3. try to make Itcl an extension which is independent of Tcl core in that it uses only published Tcl_ interfaces (that means no use of tclInt.h)
  4. to make it in the long range faster then the old version and perhaps more attractive
  5. ....
