add feature try_switch_workspace

[Schievel1]

Hey :wave:

Inspired from this discussion on the hyprland repository try_swap_workspace is a binding to mimic the 'arbitrary workspace on arbitrary monitor' on arbitrary monitor behavior known from may window managers. This means:

• if a workspace is not displayed on any monitor and should be displayed, it gets displayed on the currently focused monitor
• if a workspace is already displayed on another monitor and should displayed on the currently focused monitor, the displayed workspace on the focused monitor will be swapped with the workspace on the monitor that should be displayed on the focused monitor

I hope this helps some people that want hyprland to behave like their old windowmanager. (For me that was xmonad). I tried to mimic the existing script for scratchpatch as much as possible, I don't know how to write nix packages, though. So I skipped that.

I think the explanation already describes it well enough, but let me know if you want a screen recording. I have to figure out how to do that first then. If people come up with any other modes of how workspaces and windows should behave with multi monitors (I am bad in imagining them, but people come up with new weird stuff all the time) we can probably add some extra flags to this script to change behavior. For now lets keep it simple.

Cheers! :tada:

I've tried making a nix file for this, but when I try to build it, it complains about the Makefile. Do you know what I can do to fix this?

make: *** No rule to make target 'scratchpad', needed by 'install'.  Stop.

Provided that the script is somewhere in path I created this patch for waybar to make the on-click feature of wlr/workspaces work with this.

Maybe we can get a PR merged in waybar that makes the command configurable in the future. Hyprland (without this script) needs this as well.

Yes, I’m pretty sure I didn’t do the Makefile properly. Should be fixed now.
