E.J. Friedman-Hill's Tcl/Tk Course Tcl/Tk Programming in Five Easy Lessons

Tcl is an easy-to-learn, portable, powerful and extensible scripting language. Tk is an easy and flexible graphics toolkit for Tcl. Sun has just released a Netscape Plug-in which lets you deploy 'Tclets' on the World Wide Web. Tclets are very similar to Java applets, but much easier to write! You can use Tcl with your Windows, Macintosh or UNIX computer, and best of all, it's all free!

These are the notes for a Tcl/Tk programming class I'm putting together. They borrow liberally from a set of slides originally assembled by John Ousterhout himself.

Right now, they are available only in PowerPoint source form and in low-quality HTML form; this might change as time goes on. Note that the HTML is missing all the figures AND some of the text!

Here are the notes for Week 1 as PowerPoint, an overview of Tcl/Tk and an introduction to Tcl syntax. Here is the same thing as HTML.

Here's Week 2 as PowerPoint, a look at the complete Tcl language. Here is a ratty HTML version, and here's the stack code example.

Here's Week 3 as zipped PowerPoint. It's an incredible 7+ megabytes unzipped, but only 205,000 bytes zipped (lots of screen shots.) Here is a ratty HTML version, and here'sa worked version of the homework from last week.

Week 4 (zipped PowerPoint) presents a number of examples of text and canvas widget usage, and looks at creating Tclets for the WWW. Here is the HTML version.

Week 5 (zipped PowerPoint) discusses customizing Tcl by adding your own C code, and discusses a number of popular Tcl extensions you can download for free. Here is the HTML version.
