OTcl - Object Tcl Extensions

The CMT project has adopted OTcl as the base for the CMT Media Playback API, but unfortunately found MIT Version 0.96 to be lacking a couple of needed features, as well as not being compatible with Tcl/Tk 8.0. We are therefore including our modified version of OTcl with CMT 4.0.

What is OTcl?

OTcl, short for MIT Object Tcl, is an extension to Tcl/Tk for object-oriented programming. It shouldn't be confused with the IXI Object Tcl extension by Dean Sheenan. Some of OTcl's features as compared to alternatives are:

• designed to be dynamically extensible, like Tcl, from the ground up
• builds on Tcl syntax and concepts rather than importing another language
• compact yet powerful object programming system (draws on CLOS, Smalltalk, and Self)
• fairly portable implementation (2000 lines of C, without core hacks)

For documentation about objects, classes, and their capabilities, see the following reference pages:
