    I once had an O'Really book named 'Perl/Tk'. I mean, I still have it somewhere... I've the feeling reading through it will maybe become my AI recovery therapy at some point?

    Tcl/Tk has got to be the easiest GUI system out there; you can get simple stuff going with no effort - nothing I've seen comes close to that simplicity.

    Good to see it's getting some modern support.

    Congrats to the community and the core team. Their dedication to maintaining Tcl/Tk as a gold standard of stability, pragmatism, and lightweight cross-platform development is inspiring.

    Many VLSI CAD tools come with a tcl console window. Im gratified to see the continued language support

    Kudo’s to Mr Osterhout’s long lived legacy

    Last time I checked, there was no Wayland support (other than executing in XWayland). Has it changed?

    The cool thing is that even if you take something arguably super modern, like the latest Claude models, it is able to write Tcl/tk applications for you that you might not have done at that level in the past. With tests in tcltest too.

    If you understand how generative models and agentic coding works, it's not a surprise. But for some reason it's still mind boggling to think that you can take very old stuff and build impressive programs.

      I haven't tested this recently, but I bet it’s equally capable of writing custom Tcl extensions using the C API. Given how stable and clean the Tcl C interface has always been, it’s probably a perfect use case for LLM generation.

        Yeah should work. So that makes it possible to do literally anything. Tcl always had one foot in the old days and one foot in the modern era. It's not like ALGOL or anything.

        Now if we could just bring back Navi/AOLPress....

      Ah, the memories.

      The startup I joined in 1999 had its own application server loosely based on AOLServer architecture.

      We had Apache + mod_tcl, IIS with our own ISAPI extension, then in box connections for all major RDMS across all key UNIXes and Windows NT/2000.

      Some left to join companies doing Vignette projects, others eventually created OutSystems redoing the same ideas, but with the newly released .NET.

      However it was also a lesson in performance issues, and the constant pressure to rewrite Tcl code into C extensions.

        I used it when I worked at AOL :)

        Was great for rapid prototyping and a/b testing in volume. Not sure I'd pick it ever again for anything, but it was interesting for sure.

      Or Kenny Tilton's celtk or cello?

    Tcl/Tk has saved me back in the day. The Windows distribution BAWT/Magicsplat are timely updated

    ..... but they do not come with Next Scripting Framework.

    There was a new release on September 16, 2026

    Excellent to read Tk is getting better acessibility support. I love using it for quick little Perl/Tk GUI applications but I'm also slowly going blind from retinal tearing. It's good to see progress in some GUI toolkits when major desktops like KDE have dropped accessibility in their latest releases.
