Tcl is used for web applications, desktop GUIs, testing and automation, and more.
Tcl is a high-level language well suited for rapid development and prototyping.
The entire syntax of Tcl is described in just 12 rules.
Procedural, OO, functional; builtin event loop for network programming and asynchronous file I/O.
Coroutines allow asynchronous interleaved tasks to be written in a sequential style.
Continuous, active development since the early 1990's.
Every language has its own way of doing things. Tcl is no different. Our mentors will help you learn to think like a Tcl developer and how to write idiomatic code in Tcl. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Tcl - they'll help you discover the things you don't know that you don't know.
