Manipulate screens ordered by physical location instead of ID

This module allows you name Xinerama screens from XMonad using their physical location relative to each other (as reported by Xinerama), rather than their ScreenID s, which are arbitrarily determined by your X server and graphics hardware.

You can specify how to order the screen by giving a ScreenComparator. To create a screen comparator you can use screenComparatorByRectangle or screenComparatorByScreenId. The default ScreenComparator orders screens by the upper-left-most corner, from top-to-bottom and then left-to-right.

Example usage in your xmonad.hs file:

import XMonad.Actions.PhysicalScreens
import Data.Default

, ((modMask, xK_a), onPrevNeighbour def W.view)
, ((modMask, xK_o), onNextNeighbour def W.view)
, ((modMask .|. shiftMask, xK_a), onPrevNeighbour def W.shift)
, ((modMask .|. shiftMask, xK_o), onNextNeighbour def W.shift)

--
-- mod-{w,e,r}, Switch to physical/Xinerama screens 1, 2, or 3
-- mod-shift-{w,e,r}, Move client to screen 1, 2, or 3
--
[((modm .|. mask, key), f sc)
    | (key, sc) <- zip [xK_w, xK_e, xK_r] [0..]
    , (f, mask) <- [(viewScreen def, 0), (sendToScreen def, shiftMask)]]
