Tcl Articles

The Wiki menu Articles links to recent articles and blogs.

The index below points to just some of the older online articles about Tcl, Tk, and various extensions. Most of these articles really talk about Tcl, instead of just mentioning it along with other scripting languages.

LV I've taken a first whack at organizing this page by article year where possible. If you would like to move some items from the unorganized section to the appropriate year, please feel free to do so. Also feel free to add new articles...
