-- Module : XMonad.Actions.Commands
-- Copyright : (c) David Glasser 2007
-- License : BSD3
--
-- Maintainer : glasser@mit.edu
-- Stability : stable
-- Portability : portable
--
-- Allows you to run internal xmonad commands (X () actions) using
-- a dmenu menu in addition to key bindings. Requires dmenu and
-- the Dmenu XMonad.Actions module.
--

module XMonad.Actions.Commands (
-- * Usage
-- $usage

runCommand,

import XMonad.StackSet hiding (workspaces)

import Data.Maybe
-- $usage
--
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@:
--
-- > import XMonad.Actions.Commands
--
-- Then add a keybinding to the runCommand action:
--
-- > , ((modMask x .|. controlMask, xK_y), commands >>= runCommand)
--
-- and define the list of commands you want to use:
--
-- > commands :: X [(String, X ())]
-- > commands = defaultCommands
--
-- Whatever key you bound to will now cause a popup menu of internal
-- xmonad commands to appear. You can change the commands by changing
-- the contents of the list returned by 'commands'. (If you like it
-- enough, you may even want to get rid of many of your other key
-- bindings!)
--
-- For detailed instructions on editing your key bindings, see
-- "XMonad.Doc.Extending#Editing_key_bindings".

-- list of pairs.
