Essentially, whenever the tutorial actually has decent material on the
subject matter. The replacement is roughly done as follows:
- logHook → tutorial
- keybindings → tutorial, as this is thoroughly covered
- manageHook → tutorial + X.D.Extending, as the manageHook stuff the
tutorial talks about is a little bit of an afterthought.
- X.D.Extending (on its own) → tutorial + X.D.Extending
- layoutHook → tutorial + X.D.Extending, as the tutorial, while
talking about layouts, doesn't necessarily have a huge focus there.
- mouse bindings → leave this alone, as the tutorial does not at all
talk about them.

|
|
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.MagicFocus
|
|
--
|
|
-- Then edit your @layoutHook@ by adding the magicFocus layout
|
|
-- modifier:
|
|
--
|
|
-- > myLayout = magicFocus (Tall 1 (3/100) (1/2)) ||| Full ||| etc..
|
|
-- > main = xmonad def { layoutHook = myLayout,
