extensions for the Tcl programming language. It is widely used among the Tcl community, and is generally regarded as industrial strength . Its name is a pun on " C++". Itcl implementations exist as both a package that may be dynamically loaded by a Tcl application, as well as an independent standalone language with its own interpreter.

Overview

Features

Namespace support

Itcl allows namespaces to be used for organizing commands and variables. Example: package require Itcl itcl::class Toaster itcl::class SmartToaster set toaster martToaster #auto$toaster toast 2

C code integration

Itcl (like Tcl) has built-in support for the integration of C code into Itcl classes.
