--
-- Dwm-like promote function for xmonad.
--
-- Swaps focused window with the master window. If focus is in the
-- master, swap it with the next window in the stack. Focus stays in the
-- master.
--
-- To use, modify your Config.hs to:
--
-- import XMonadContrib.DwmPromote
--
-- and add a keybinding or substitute promote with dwmpromote:
--
-- , ((modMask, xK_Return), dwmpromote)
--
module XMonadContrib.DwmPromote (dwmpromote) where
import XMonad
import Operations (windows)
import StackSet hiding (promote)
import qualified Data.Map as M
dwmpromote :: X ()
dwmpromote = windows promote
promote :: (Integral i, Ord a) => StackSet i j a -> StackSet i j a
promote w = maybe w id $ do
a <- peek w -- fail if null
let stack = index (current w) w
let newstack = swap a (next stack a) stack
return $ w { stacks = M.insert (current w) newstack (stacks w),
focus = M.insert (current w) (head newstack) (focus w) }
where
next s a | head s /= a = head s -- focused is not master
| length s > 1 = s !! 1
| otherwise = a
