? (Can we hardcode /tmp?)

We could use System.Directory.getTemporaryDirectory just to be on the safe side.

Sure. So:

hunk ./XMonad/Core.hs 446 +    tmp <- getTemporaryDirectory hunk ./XMonad/Core.hs 461 -            waitForProcess =<< runProcess "ghc" ["--make", "xmonad.hs", "-i", "-ilib", "-fforce-recomp", "-v0", "-o",binn] (Just dir) +            waitForProcess =<< runProcess "ghc" ["--make", "xmonad.hs", "-i", "-ilib", "-fforce-recomp", "-hidir", tmp, "-odir", "/tmp", "-v0", "-o",binn] (Just dir)

Note that this compiles and leaves in my /tmp a Main.o and a Main.hi, with no intermediates in ~/.xmonad, but xmonad --restart doesn't seem to work for me; I am unsure whether the failure of --restart is part of my general bugginess or related to this edit. Other people trying it out would be good.

Since no one has tried this, or tried it and complained, I'm sending in a patch to do this. -- gwern
