Hi, I'd like to get XMonad to spawn an xmobar for each monitor based on the current number of montiors that are present. This includes spawning new instances when monitors appear and tearing them down when they're taken offline[1]. I've gotten most of the logic done (on a branch that I've neglected to push from my work machines yet) and it involves some code from adamvo's config[3] including getScreens, multiPP, and mergePPOutputs which would indeed be good to get into contrib. In my case, since I use xmonadpropwrite for xmobar so that a single xmobar launch works independently of xmonad, it also requires a change in xmobar itself to accept *supplemental* commands to run from the command line. A branch with this support is on my github fork[4]. The last part is where I've hit a snag. I've tried to get some Xrandr support into the X11 package, but my experience with the FFI is pretty much nil and I've been unable to get something that looks/feels good beyond what is already done in xmobar itself. There's also the question of whether an X11-Xrandr package makes more sense (Xinerama is already there, but xft isn't). I imagine xmobar would also pick up the code that gets put into X11 or X11-Xrandr for its Xrandr needs instead of its own bindings if/when that happens. Thoughts? --Ben [1]Ideally, this could be toggled so that xmobar doesn't appear when it isn't wanted (presentations come to mind). X.H.ToggleHook[2] could probably help there.
