I wanted to try and get a pop-up message shown on a key-press showing the current mpd information. Preferably, I'd like to keep everything inside xmonad rather than relying on external scripts.
Now, I could have something like "mpc | head -1 | dzen"... but I wanted to use something like notify-send (part of libnotify) to do so, as its less obtrusive and handles non-Latin characters better (i.e. using fontconfig, etc.).
However, since notify-send doesn't seem to want to take piped inputs, I'd first have to read and parse the mpc data before I could call notify-send. This would work well... if only xmonad let me read data from the processes it spawns. As such, I think there should be a new operation that lets you obtain the stdout output from the programs that are spawned... something like "spawnOutput :: String -> m String".
Is such a thing feasible/possible/good? I _could_ just have a seperate bash script to do this, but I'd like it to have my settings as self-contained as possible. -- Ivan Lazar Miljenovic
