If I just put "firefox" then it works, but "firefox || firefox" does not, leading me to believe the command is no longer executed through the shell. Is this intentional?
This is documented in the haddocks:
-- | 'action' is an executable to be run via 'safeSpawnProg' (of
"XMonad.Util.Run") if the Window cannot be found.
-- Presumably this executable is the same one that you were looking for.

can call out to the shell to check with 'which' with the following expression you can put where you had runOrRaiseNext:
do (_,paths,_) <- io $ readProcessWithExitCode "which" ["firefox-3.5","firefox3","firefox"] "" -- run the first one that exists case lines paths of firefox : _ -> runOrRaiseNext firefox ... _ -> return () -- or something else?
Another solution is to look at the current code: runOrRaise = raiseMaybe ○ safeSpawnProg XMonad.Util.Run.safeSpawnProg is defined as: safeSpawnProg ∷ MonadIO m ⇒ FilePath → m () safeSpawnProg = flip safeSpawn [] In comparison, XMonad.Util.Run.unsafeSpawn: unsafeSpawn ∷ MonadIO m ⇒ String → m () unsafeSpawn = spawn And String == FilePath, so these type signatures are identical. So to restore the old behavior is as simple as swapping B for A: runOrRaise' = raiseMaybe ○ unsafeSpawn I thought this was all clear in the haddocks, but I guess not. I've expanded the haddock for runOrRaise to point out raiseMaybe's greater generality. -- gwern
