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`.

-- $usage
|
|
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
|
|
--
|
|
-- > import XMonad.Prompt
|
|
-- > import XMonad.Prompt.Layout
|
|
--
|
|
-- > , ((modm .|. shiftMask, xK_m ), layoutPrompt def)

-- For detailed instruction on editing the key binding see

|
-- "XMonad.Doc.Extending#Editing_key_bindings".
|
|

|
|
-- WARNING: This prompt won't display all possible layouts, because the
|
|
-- code to enable this was rejected from xmonad core. It only displays
|
|
-- layouts that are actually in use. Also, you can only select layouts if
|
|
-- you are using NewSelect, rather than the Select defined in xmonad core
|
|
-- (which doesn't have this feature). So all in all, this module is really
|
|
-- more a proof-of-principle than something you can actually use
|
|
-- productively.
