A good craftsman has a good set of tools, and knows how to use them best. The general recommendation is: "Use the best tool for the job". The traditional, "procedural" approach would beĪ more practical aspect is that Tcl is very open for "language-oriented programming" - when solving a problem, specify a (little) language which most simply describes and solves that problem - then go implement that language. See "Tcl examples" below for ideas what one can do. One language, many styles Īlthough a language where "everything is a command" appears like it must be "imperative" and "procedural", the flexibility of Tcl allows one to use functional or object-oriented styles of programming very easily. Unix shells (but with more powerful structuring).C (control structure keywords, expr syntax) and.LISP/Scheme (mainly for its tail-recursion capabilities),.However, Tcl is a programming language in its own right, which can be roughly described as a cross-breed between It is very easy to add new functions to the Tcl interpreter, so it is an ideal reusable "macro language" that can be integrated into many applications. The interpreter is implemented as a C library that could be linked into any application. Tcl was originally developed as a reusable command language for experimental computer aided design (CAD) tools. Although Tcl is a string based language there are quite a few object-oriented extensions for it like Snit, incr Tcl, and XOTcl to name a few. The language features far-reaching introspection, and the syntax, while simple, is very different from the Fortran/Algol/C++/Java world. That is why Tcl is now more commonly called Tcl/Tk. The first major GUI extension that works with Tcl is Tk, a toolkit that aims to rapid GUI development. The current stable version, in February 2008, is 8.5.1 (8.4.18 in the older 8.4 branch). Tcl was created in 1988 by John Ousterhout and is distributed under a BSD style license (which allows you everything GPL does, plus closing your source code). While Tcl is flexible enough to be used in almost any application imaginable, it does excel in a few key areas, including: automated interaction with external programs, embedding as a library into application programs, language design, and general scripting. Tcl runs on almost all modern operating systems such as Unix, Macintosh, and Windows (including Windows Mobile). Tcl is a radically simple open-source interpreted programming language that provides common facilities such as variables, procedures, and control structures as well as many useful features that are not found in any other major language. The name Tcl is derived from "Tool Command Language" and is pronounced "tickle". 8.22 A little deterministic Turing machine.8.15.3 Functional programming (Backus 1977).8.12 Experiments with Boolean functions.5.4 Unicode implementations: UTF-8, UCS-2/UTF-16.5.3 Unicode as pivot for all other encodings.2.1.3 Argument passing by name or value.
