Although Tcl 9 is now out and the best release ever, Tcl 8.6 is still maintained. Tcl/Tk 8.6.17 has just been released with some fixes and improvements!. Announcement: 🔗 Download the sources from here: 🔗

Updates to the tablelist and tsw packages:. - tablelist version 7.7 has some new features and improvements. - tsw version 1.2 comes with some platform- and theme-specific improvements. 🔗

What do you want to know?.

The story continues! After having launched Tcl 9.0 last year, the development focuses on Tcl 9.1 and here is the first alpha release!. 🔗 🔗 (That newsgrouper site is actually runs on Tcl if you didn't that already!).

You may implicitly just want an empty string here but the dict is not initialized like this. In Tcl 9 you can now do:. dict getwithdefault $myDict someKey {}. and you get the empty string. Of course, any other value can be used as the default when the key is not defined!.

New features in #Tcl9 – part 13:. dict getwithdefault — Define a fallback value to use when dict get would otherwise fail. You know it from Tcl 8.6. You do. dict get $myDict someKey. and get back an error because 'someKey' is not present.

Now, what is even nicer: you can try eTcl in the browser via WebAssembly!. Just go here and find a running console window. Then just start typing Tcl commands. You can even `package require Tk` and start using widgets and everything that Tk offers!!. 🔗

eTcl comes with a comprehensive set of custom extensions, e.g. pixane & EvoGPU (a cross-platform GUI framework). 🔗

eTcl used to be a a Tcl/Tk distribution as a single standalone executable. Now, it has been revived, running Tcl 9.0.2, providing a modernized version of the cross-platform runtime engine. The supported platforms are Linux, Windows, macOS and even Web (Wasm32 and Wasm64)!.

A film about "The Tcl story"? Well, not completely, but close. See this new Youtube video called "The Most MISUNDERSTOOD Programming Language". 🔗

Version 9.0.2 of Tcl and Tk have just been released yesterday!. They contain quite a number of bug fixes, package updates plus a few new features regarding encodings and the ttk::panedwindow sash. Here are the announcements:.🔗 🔗

The updated 'argparse' package gives you a powerful argument parser command capable of flexibly processing and validating many varieties of switches and parameters. See all details here:.🔗

Argument parsing can be quite complex when you write some Tcl procedures with lots of arguments with switches and mandatory/optional components.

Now do:. puts $fläche. can't read "fl": no such variable. As Tcl's variable substitution rule only takes names in ASCII, Tcl stops reading when seeing the "ä" and looks for a variable called "fl" 😱. So be careful!.

Good to know about Tcl:. Although Tcl is fully utf-8 aware and capable, variable names are only ASCII. Assume you want a variable name "fläche" (the German word for "area"). set fläche 45. You get no error. Because the [set] command does not care. It takes utf-8 🙂.
