Notes on Wayland and clipboard support

Running espanso as another user

When running espanso as another user, we need to set up a couple of permissions in order to enable the clipboard tools to correctly connect to the Wayland desktop.

In particular, we need to add the espanso user to the same group as the current user so that it can access the /run/user/X directory (with X depending on the user).

# Find the current user wayland dir with
echo $XDG_RUNTIME_DIR  # in my case output: /run/user/1000

ls -la /run/user/1000

# Now add the `espanso` user to the current user group
sudo usermod -a -G freddy espanso

# Give permissions to the group
chmod g+rwx /run/user/1000

# Give write permission to the wayland socket
chmod g+w /run/user/1000/wayland-0

Now the clipboard should work as expected

Better implementation

On some Wayland compositors (currently sway), the "wlr-data-control" protocol could enable the use of a much more efficient implementation relying on the "wl-clipboard-rs" crate.
