This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.

-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Layout.Dishes
|
|

|
|
-- Then edit your @layoutHook@ by adding the Dishes layout:
|
|
--
|
|
-- > myLayout = Dishes 2 (1/6) ||| Full ||| etc..
|
|
-- > main = xmonad def { layoutHook = myLayout }
