xmonad-keybindings-query

This module allows you to create XMonad key-bindings that do different things depending on the current window state.

Warning: This module is very new and I am still a journeyman with respect to Haskell development. There is likely room for improvement here.

Basic Usage

This module works similarly to XMonad.ManageHook; however, instead of querying the state of a window to determine where it appear on-screen, we query it to decide what IO action to execute.

import XMonad.KeyBindings.Query

main = xmonad def `additionalKeys`
          [ ((mod4Mask .|. shiftMask, xK_z), appSpecificKey)
          , ((mod4Mask .|. shiftMask, xK_x), appSpecificKeyWithDefault)
          ]
  where
    appSpecificKey = queryFocused' $ composeOne
      [ isDialog               -?> safeSpawn "notify-send" ["this is a dialog"]
      , className =? "firefox" -?> safeSpawn "notify-send" ["firefox is focused"]
      ]

    appSpecificKeyWithDefault = queryFocused defaultAction $ composeAll
      [ isDialog              -?> safeSpawn "notify-send" ["this is a dialog"]
      , title =? "Save Image" -?> safeSpawn "notify-send" ["this is a save image dialog"]
      ]

    defaultAction = safeSpawn "notify-send" ["no window is focused"]

Things to try

Here are some ideas you can try:

• App-specific hotkeys. You can use configure the same hotkeys to do different things, depending on what window is currently focused.
• Desktop hotkeys. You can define hotkeys for only when no window is focused. Why not define a bunch of hotkeys to launch your favourite apps in this case?
