This isn't entirely related, but since people are discussing ShellPrompt... before I switched to ShellPrompt from dmenu, I had this line:
 prompt :: String -> X ()
 prompt app = spawn (app ++ " `echo " ++ app ++ " | dmenu -fn '9x15bold,xft:Bitstream Vera Sans Mono' -nb black -nf white -sf green -sb black`")

It would prompt you for a string and then run the 'app' with that string through use of the pipe; pretty nifty. This was incredibly handy for working with Surfraw's elvi (shell scripts that would open up specified web pages/web searches). I eventually figured I could replace it with:

 prompt :: String -> X ()
 prompt c = mkXPrompt Shell greenXPConfig getShellCompl foo
  		          where foo a = spawn (c ++ " " ++ a)

But this strikes me as inelegant. Is there any better way, do you think/.
