Linux/X11 Window Switcher plugin for Ulauncher
License: GNU General Public License v3.0
This is a plugin for Ulauncher that lets you search & switch between Linux/X11 Windows by name:
The default keyword in win, so just run Ulauncher, then type win <query> to filter the window list, then select a window from the list to switch to that window.
I used window icons from the Obsidian Icon pack
You need wmctrl installed. See: https://www.freedesktop.org/wiki/Software/wmctrl/
For Debian/Ubuntu, you can do:
$ sudo apt install wmctrl
I'm using Pop!_OS 22.04.
The window-switching works great, except that the window I switch to doesn't have focus; meaning that, for example, in my code editor, I have to click before I can start typing. This happens even if I previously had focus and switch back to the same window again using this plugin; it somehow manages to lose focus in the process, and I must click or otherwise manually regain focus.
Unfortunately this makes the plugin unusable for me :/
I'm trying to use this extension on Arch and it crashes and exits right away.
The related error message seems to be:
2021-04-16 09:54:28,304 | ERROR | ulauncher.api.server.ExtensionRunner: _run_process() | Extension "com.github.dflock.ulauncher-window-switcher" exited instantly with code 1

Since Arch is a bit aggressive with updating Gnome I suspect that 3.0 might be widely used by some other distros, but maybe it's possible to write the extension in such a way that it supports both versions?
Hi, I moved the icon folder "Obsidian" into usr/share/icons as suggested but nothing changes. Did I do something wrong? thanks a lot

Good day, I'm on debian 12 stable, xfce, installing the extension does not work, does not detect the any window
It would be great, to show the corresponding icon next to the applications in the list.
After installing, the extension crashes and the following message appears:
The extension exited instantly. Please check the logs.
I can't even change and save the keyword for triggering the extension.

I am using Ulauncher v5.10.0 on Kubuntu 20,04 with i3-gaps as the window manager.
When trying to switch windows and after typing 'win ' ulauncher displays a single item 'Loading...' - but nothing ever loads. No entries are made in the logs so I am unsure what is causing the issue.
ulauncher allows fuzzy search out of the box.
fuzzy-window-switcher allows switching to windows with fuzzy search (https://github.com/XCMer/fuzzy-window-switcher).
It would be great, if ulauncher-window-switcher would also allow fuzzy search.
