-- Module : XMonad.Prompt.Layout
-- Copyright : (C) 2007 Andrea Rossato, David Roundy
-- License : BSD3
--
-- Maintainer : droundy@darcs.net
-- Stability : unstable
-- Portability : unportable
--
-- A layout-selection prompt for XMonad
--
-----------------------------------------------------------------------------
module XMonad.Prompt.Layout (
-- * Usage
-- $usage
layoutPrompt
) where
import Data.List ( sort, nub )
import XMonad hiding ( workspaces )
import XMonad.Prompt
import XMonad.StackSet ( workspaces, layout )
import XMonad.Layout.LayoutCombinators ( JumpToLayout(..) )
-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Prompt
-- > import XMonad.Prompt.Layout
--
-- > , ((modMask x .|. shiftMask, xK_m ), layoutPrompt defaultXPConfig)
--
-- 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.
