i3-focus-last VS i3ipc-python

I've actually found https://github.com/lbonn/i3-focus-last after releasing this project, which may be what you are looking for. It's definitely a different approach this this solution.

There's also a rust version https://github.com/lbonn/i3-focus-last

If you would like dmenu integration as well, I can personally recommend this: https://github.com/lbonn/i3-focus-last

i3ipc-python seems to do what I want -- it even has a script specifically for this -- and for existing windows moving to the space I think I can just use the binding.

Any reason not to use i3ipc-python? The module will talk over the ipc socket rather than calling out to (relatively expensive) i3-msg subprocesses to do it.

Untested but with i3ipc-python you should be able to write a script something like this:

here you go, there's more stuff on the arch wiki

And this is the specific script to focus the last focused workspace https://github.com/altdesktop/i3ipc-python/blob/master/examples/focus-last.py

Looks good, if you want to go even further you could replace calls to swaymsg with a python implementation python-i3ipc / i3ipc-python

I could probably use the i3ipc-python (https://github.com/altdesktop/i3ipc-python) library (which works with both i3 and Sway) to make a Sway-specific implementation, but then it would be up to other people to implement support for things like KDE Wayland and Gnome Wayland.

This is kind of interesting for me. I ran into a problem with spotify, I couldn't assign it to its proper workspace... The reason was because spotify does not put proper values in at startup (sometimes it manages, but mostly not), in bspwm there were subscribe that just dumped data out. I3 you can subscribe as well, but it seems they want you to use more libraries. I found this https://i3wm.org/docs/ipc.html, through that I found https://github.com/altdesktop/i3ipc-python, installed it with

The end goal is to make something that interacts with https://github.com/altdesktop/i3ipc-python, or something similar, so I'm fine with something closer to a library.
