passmenu + wofi, inelegantly hacked together to work with wl-copy & sway
It's zx2c4's wonderful passmenu script, modified to work with rofi & sway.
Essentially, I took out the xdotool part, and use wofi instead of dmenu. It then clears the clipboard after 45 seconds.
Add something like this to your sway config:
set $passmenu /home/alex/git/dotfiles/scripts/passmenu-rofi-wayland
bindsym $mod+Shift+P exec $passmenu
I'm sure this can be improved, but this has been working for me great so far.
