These are Go bindings for Tk, a cross-platform widget toolkit initially developed as extension for Tcl. Nowadays a lot of languages have bindings for Tcl/Tk. Python for example has been including tkinter [0] for a long time.

Really? Would love to see a binding for Powershell. Just for cross-platform shell scripts to be able to disable a pop-up for input etc. Just makes them more accessible.

That would be WPF. It uses Tk under the covers.

Ah, my bad. It is inspired by Tk. Should still be usable across most things today.

I believe that has been removed in later versions as the old examples I find online don't work in Powershell

This still works today for me:

    Add-Type -AssemblyName PresentationFramework
    [XML]$form = @"
       <Window 
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            Title="MainWindow" Height="450" Width="800">
        <Grid>
            
        </Grid>
        </Window>
    "@

    $NR = (New-Object System.Xml.XmlNodeReader $form)
    $window = [Windows.Markup.XamlReader]::Load($NR)

    $window.ShowDialog()

yes, perl, python and ruby, for example.

yes, for python, from 1.5 or early 2.x versions onwards, iirc. I've used py a bit from 1.5 and much more from early 2.x, is how i know this.

Seems Tk is now the default cross platform UI for any language. It is doing for local apps what JavaScript has not - a usable toolset for majority of use cases without a ton of overhead and interference. I e only played with tcl/tk over the years - now will put in some hard yards to try in depth. Golang+tk for heavy lifting and server side and tcl/tk for scripts and as hoc things. After 50 years of casual/prof development this might be my personal version of nirvana. YMMV.

So let's hope someone writes a wasm binding.

Similarly to Python Tkinter, it actually embeds Tcl/Tk and provides a Go interface to it.

And latest Tcl/Tk is v9 I think. So I guess there should be something...
