About Tcl

Tcl, pronounced "tickle" and short for Tool Command Language, is a dynamic, open source programming language.

It was designed with the goal of being very simple but powerful. It is so simple that the entire syntax is fully described in just 12 rules. Yet it is a fully-featured programming language.

Tcl casts everything into the mold of a command, even constructs like variable assignment, procedure definition and control flow. As such, it resembles both shell scripting and Lisp.

Tcl supports multiple programming paradigms, including object-oriented, imperative and functional styles. The most common use-cases of Tcl are as embedded scripting run-times in C applications, and for prototyping GUIs using the Tk GUI toolkit.

You can read more about Tcl on the following websites:

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

I first learned Tcl in the mid-90's, and it has been my one true (language) love ever since. It's simplicity is remarkable: the entire syntax is described in just 12 rules. I look forward to helping others learn it.
Fun. Challenging. Interesting

I've been programming in Tcl since version 8.0. I find it very refreshing to have a language that can be described in just 12 rules.

I learned Tcl in the mid-1990s along with Perl. They were my first languages, and Tcl appealed especially to me because it was so easy to learn.

Get started with the Tcl track. As with everything on Exercism, it's 100% free!
