Provides functionality to use key chords to focus a visible window. Overlays a unique key chord (a string) above each visible window and allows the user to select a window by typing that chord. Inspired by vim-easymotion. Thanks to Tom Hinton for some feature inspiration and window sorting code.



You can use this module's basic functionality with the following in your xmonad.hs:

   import XMonad.Actions.EasyMotion (selectWindow)

To customise

   import XMonad.Actions.EasyMotion (selectWindow, EasyMotionConfig(..))

Then add a keybinding and an action to the selectWindow function. In this case M-f to focus the selected window:

   , ((modm, xK_f), selectWindow def >>= (`whenJust` windows . W.focusWindow))

Similarly, to kill a window with M-f:

   , ((modm, xK_f), selectWindow def >>= (`whenJust` killWindow))

See EasyMotionConfig for all configuration options. A short summary follows.

Default chord keys are s,d,f,j,k,l. To customise these and display options assign different values to def (the default configuration):

   , ((modm, xK_f), (selectWindow def{sKeys = AnyKeys [xK_f, xK_d]}) >>= (`whenJust` windows . W.focusWindow))

You must supply at least two different keys in the sKeys list. Keys provided earlier in the list will be used preferentially—therefore, keys you would like to use more frequently should be earlier in the list.

To map different sets of keys to different screens. The following configuration maps keys fdsa to screen 0 and hjkl to screen 1. Keys provided earlier in the list will be used preferentially. Providing the same key for multiple screens is possible but will break down in some scenarios.

   import qualified Data.Map.Strict as StrictMap (fromList)
   emConf :: EasyMotionConfig
   emConf = def { sKeys = PerScreenKeys $ StrictMap.fromList [(0, [xK_f, xK_d, xK_s, xK_a]), (1, [xK_h, xK_j, xK_k, xK_l])] }
   -- key bindings
   , ((modm, xK_f), selectWindow emConf >>= (`whenJust` windows . W.focusWindow))

To customise the font:

   , ((modm, xK_f), (selectWindow def{emFont = "xft: Sans-40"}) >>= (`whenJust` windows . W.focusWindow))

The emFont field provided is supplied directly to the initXMF function. The default is "xft:Sans-100". Some example options:

   "xft: Sans-40"
   "xft: Arial-100"
   "xft: Cambria-80"

Customise the overlay by supplying a function to overlayF. The signature is Position -> Rectangle -> Rectangle. The parameters are the height in pixels of the selection chord and the rectangle of the window to be overlaid. Some are provided:

   import XMonad.Actions.EasyMotion (selectWindow, EasyMotionConfig(..), proportional, bar, fullSize)
   , ((modm, xK_f), (selectWindow def{ overlayF = proportional 0.3  }) >>= (`whenJust` windows . W.focusWindow))
   , ((modm, xK_f), (selectWindow def{ overlayF = bar 0.5           }) >>= (`whenJust` windows . W.focusWindow))
   , ((modm, xK_f), (selectWindow def{ overlayF = fullSize          }) >>= (`whenJust` windows . W.focusWindow))
   , ((modm, xK_f), (selectWindow def{ overlayF = fixedSize 300 350 }) >>= (`whenJust` windows . W.focusWindow))

selectWindow :: EasyMotionConfig -> X (Maybe Window) Source #

Display overlay windows and chords for window selection


data EasyMotionConfig Source #

Configuration options for EasyMotion.

All colors are hex strings, e.g. "#000000"

If the number of windows for which chords are required exceeds maxChordLen, chords will simply not be generated for these windows. In this way, single-key selection may be preferred over the ability to select any window.

cancelKey, xK_BackSpace and any duplicates will be removed from sKeys if included. See Usage for examples of sKeys.

The default value for this type.

Creating overlays

fullSize :: Position -> Rectangle -> Rectangle Source #

Create overlay windows of the same size as the window they select

fixedSize :: (Integral a, Integral b) => a -> b -> Position -> Rectangle -> Rectangle Source #

Create fixed-size overlay windows

textSize :: Position -> Rectangle -> Rectangle Source #

Create overlay windows the minimum size to contain their key chord

proportional :: RealFrac f => f -> Position -> Rectangle -> Rectangle Source #

Create overlay windows a proportion of the size of the window they select

bar :: RealFrac f => f -> Position -> Rectangle -> Rectangle Source #

Create overlay windows the full width of the window they select, the minimum height to contain their chord, and a proportion of the distance from the top of the window they select
