Klipper backend appears to fail silently on Plasma 6 + Wayland #258

Open afontenot opened 6 months ago

On Arch Linux.

Distribution metadata says that plasma-workspace provides the klipper backend for pyperclip:

plasma-workspace: klipper backend [installed]

I have version 6.0.2 of plasma-workspace installed, and 1.8.2 of pyperclip.

pyperclip.copy("test")

Does not seem to do anything, with no other backends installed. If I install wl-clipboard, it works as expected. Is the Klipper API legacy / X11 only? If so I'd expect the backend to fail in pyperclip and receive an actionable error.

On my arch linux, my pyperclip also fails on plasma-workspace 6.1.0-1 and pyperclip 1.8.2. However, I'm using X11. I copied the newest master branch and tried again, but on calling paste(), it still gave me the following error:

Traceback (most recent call last):

On Linux, you can run `sudo apt-get install xclip` or `sudo apt-get install xselect` to install a copy/paste mechanism.

According to this post, it seems that klipper is a plasmashell applet now. So maybe the "klipper backend" is actually unusable, but the package maintainer in Arch Linux doesn't realize this point?
