Tool Command Language was invented by John Ousterhout as a way to make it easy to write little languages for configuring EDA tools, but it has grown far beyond those humble beginnings to become a general scripting language with built-in asynchronous I/O and Unicode strings while supporting paradigms such as object-oriented programming and coroutines.

Tool Command Language was invented by John Ousterhout as a way to make it easy to write little languages for configuring EDA tools, but it has grown far beyond those humble beginnings to become a general scripting language with built-in asynchronous I/O and Unicode strings while supporting paradigms such as object-oriented programming and coroutines. See the Wikipedia page for Tcl for more information.

The current recommended production release of Tcl is Tcl/Tk 8.6.11 (Dec 30, 2020).

Previous versions of the language are currently relatively common. Tcl 8.5 is widely deployed (current patch version 8.5.18). As is Tcl 8.4 in more conservative deployments (8.4.20 is current, but end-of-lifed there). Use of Tcl 8.4 or earlier is usually not recommended, as it does not receive security-fix support from the Tcl developers.

Naming

You may write the language name as either TCL or Tcl; practitioners tend to prefer the latter on the grounds that it means they don't have to hold the shift key down so long. For pronunciation purposes, either “tee cee ell” or “tickle” are acceptable, depending on audience.
