This removes the emptyLayoutMod method from the LayoutModifier class, and change the Stack parameter to redoLayout to a Maybe Stack one. It also changes all affected code. This should should be a refactoring without any change in program behaviour.

-- $usage
|
|
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.LayoutHints
|
|
--
|
|
-- Then edit your @layoutHook@ by adding the LayoutHints layout modifier
|
|
-- to some layout:
|
|
--
|
|
-- > myLayouts = layoutHints (Tall 1 (3/100) (1/2)) ||| Full ||| etc..
|
|
-- > main = xmonad defaultConfig { layoutHook = myLayouts }
|
|

|
