Aloha! I used to run krunner inside a hyprland session by invoking krunner via hotkeys or console.
Yesterday I removed plasma-desktop as hyprland does all I need except krunner. I kept the krunner package, but the executable “krunner” is no longer found. Anything I can do except installing the whole plasma-desktop again?
I use the maths functionality and find the unit conversion handy to have, though I admit I cannot remember using it ;)
If you tinker with programming , you can look into ags - aylurs gnome shell. His dotfiles include an app launcher in it, adding this functionality should not be too hard.
