Tcl, Tcl/Tk and Expect - General

Exercises, examples and other material relating to training module T050. This module is presented on Private Courses and Specially Run Courses only

Background

Tcl is a language designed to provide an environment in which engineers can tailor generic applications written in C - and as such you'll find it used in industries like IC design and Numerical Control. If you add Tk, you get a powerful Graphic User Interface that's great for writing window base applications, and Expect provides a powerful front control for command line processes that would otherwise be difficult to automate.
