Tcl/Tk Community Resources

The worldwide community of Tcl/Tk developers is certainly one of the most important assets available. This large and helpful community is a constant source of ideas, code samples, extensions, applications, and technical support.

This page highlights some of the most important resources that the community provides. Get to know them all to make the most of your experience with Tcl/Tk.

The Tcler's Wiki

A highly collaborative and rapidly evolving site, the Tcler's Wiki is a veritable treasure trove of Tcl and Tk tips, tricks and trivia. An active wiki for wide ranging discussions, code snippets and advice ranging from immensely useful to highly obscure, the site is a good first stop when faced with "I wonder if anyone has done...".

The comp.lang.tcl Newsgroup

Since the very earliest days of Tcl and Tk, the Usenet group news:comp.lang.tcl (or via Google) has been the best forum for general discussion of Tcl/Tk, along with it's various extensions and related software. A companion announcements group is also available (news: or via Google.)

The Tcler's chat, and related channels

A companion to the wiki, the Tcler's chat provides a popular real-time hangout for many Tcl experts and newcomers alike. Accessible via Jabber clients or via an IRC gateway, it's no surprise that many prefer the TkChat application.

This chat is further bridged to a Slack channel as well.

Mailing Lists

A number of more specialized mailing lists are available which discuss particular sub-topics of interest to the Tcl/Tk community.

There is also an annual European Tcl/Tk Conference, with videos of the presentations from the last few available on YouTube.
