Tcl Developer Site

Welcome to the Tcl Developer Xchange!

Join the many thousands of software developers who are already
more productive with help from the
Tcl programming language and the
Tk graphical user interface toolkit.

Tcl (Tool Command Language) is a very powerful but easy to learn dynamic
programming language, suitable for a very wide range of uses, including
web and desktop applications, networking, administration, testing and
many more. Open source and business-friendly, Tcl is a mature yet
evolving language that is truly cross platform, easily deployed and
highly extensible.

Tk is a graphical user interface toolkit that takes developing desktop
applications to a higher level than conventional approaches. Tk is the
standard GUI not only for Tcl, but for many other dynamic languages, and
can produce rich, native applications that run unchanged across Windows,
Mac OS X, Linux and more.

Core Development

A wide variety of developers contribute to the open source Tcl and Tk
core, which is hosted at core.tcl-lang.org.
The Tcl Core Team (TCT) helps steer
this development through mechanisms like Tcl Improvement Proposals (TIP’s) and the core mailing list.

Read More about how the Tcl/Tk core is developed, and how you can help.

Tcl/Tk Community

The vibrant Tcl user community provides a variety of support resources to
help working with Tcl/Tk. Among others, the Tcler’s Wiki
provides a constantly updated set of tips and tricks, while
comp.lang.tcl remains the best forum for Tcl/Tk discussions.
Beyond that we also have IRC, Slack, and Twitter channels.
