The preferred pronunciaiton is as its individual letters. In the past, the most popular pronunciation was as a homophone for "tickle". The suggested spelling is with an uppercase "T" and "cl". http://purl.org/net/tcl-faq/ is a series of pointers to other documents. http://tcl.sf.net/ hosts Tcl releases, and various extensions, .e.g, [thread]. The [CVS] also shows the sample [TEA] extension code residing in this project - unfortunately, it does not yet appear that this code has been released as a package. It is, thank goodness, available from the CVS as well as from the CVS snapshot repository at ftp://www.tcl.tk/pub/tcl/nightly-cvs/ . Besides being the home for Tcl, the tcl SF.net project is also the home for other modules, such as [tcltutorial], [thread], [SampleExtension%|%sample extension%|%], as well as the FAQs, pieces of code which are being integrated into future versions of Tcl and other miscellaneous things. Read [to build and test Tcl] for more information on creating an executable library and stand alone scripting framework from the Tcl source code distribution. [Binary Distributions] and [places to find Tcl binaries and sources] are two pages to discuss locating Tcl binaries. http://www.tcl.tk/software/tcltk/platforms.html details the platforms known to support Tcl and [Tk]. http://de.wikipedia.org/wiki/Tcl is a German wiki with useful articles on Tcl. http://en.wikipedia.org/wiki/Tcl is the English version. Could use some care and updating... ** [syntax] ** ** [Tcl Syntax] ** see [Tcl Syntax] ** [Tcl Commands%|%Commands%|%] ** see [Tcl Commands] ** Programs ** [A Tcl repository]: [Extensions for Tcl and Tk]: ---- How do you know you are using Tcl? That's a good question - in some cases, Tcl is inside a product and you may or may not even have access to the scripting engine itself. However, if you are wanting to write and execute a tcl script, you have a number of options. * Out of the box, '''[tclsh]''' is a stand alone interpreter build from the tcl source code distribution * '''[wish]''' is a tcl interpreter with the Tk [extension] pre-loaded. It is created when building [Tk]. * [tclkit] is a all-in-one-file combination of Tcl, Tk, [Metakit], [Itcl], [tclvfs] and a few other extensions. It is used for code in [starkit] format. * '''[expect]''' is a tcl interpreter with the expect extension pre-loaded. It is created when building expect. * A command called '''tcl''' (as well as '''wishx''') used to be built and installed as a part of building and installing the [Tclx] extension. * '''itclsh''' is a tclsh pre-extended with [Itcl]. * '''tixwish''' is built and installed as a part of the [Tix] build process * '''bltsh''' and '''bltwish''' are built and installed as a part of the [BLT] build process. * '''tcldomsh''' is built and installed as a part of the [TclDOM] build process * '''xotclsh''' and '''xowish''' are built and installed as a part of the [XOTcl] build process. As of Tcl 8.4, the only interpreters that you really need to think about are '''tclsh''', '''tclkit''', and (on some platforms) '''wish''', as Tcl provides the ability to dynamically load any of the other extensions during runtime. In fact, many of the extensions have been dropping the building and installing of custom executables due to this. [Tcl Commands] documents all the Tcl commands available in the [core] [distribution]. [Tcl C API] documents all the public Tcl C calls that a C programmer should consider ''safe'' to use. Tcl also comes with several [package]s. For instance, the [http] package, [dde], [msgcat], [platform], [registry], [tcltest], the deprecated [optparse] package, as well as others [[please fill them in here]]. ---- [64-bit computing] ---- The arts and crafts link, below, will lead you to tutorials and other useful information about Tcl as a programming language. ---- [LV] There is a directory entry for Tcl and [Tk] at http://directory.fsf.org/project/tclTk/ - the [FSF] directory of free software. However, the entry is 3 years old, refers to 8.5 alpha, makes references to the source being maintained on sourceforge, etc. Someone with time to spend advocating Tcl in the public eye might consider tracking down the process of updating that page, updating this note to add that discovery, and then submit an update bringing the information up to date. Just a thought. ---- * [Arts and crafts of Tcl-Tk programming] * [The way tcl works] * [Tcl Command Evaluation: Layer by Layer] <> Language | Tcl Implementations
