XMonad gaps in fullscreen

Question

I am trying to set up XMonad so that multiple windows have gaps between them. The relevant part of my config file is as follows

import XMonad.Layout.Spacing

followed later by

myLayout = tiled ||| Mirror tiled ||| Full
  where
    tiled = spacing 5 $ Tall nmaster delta ratio
    nmaster = 1
    ratio = 1/2
    delta = 3/100

The problem is that when one window occupied the whole screen there are gaps along the border. Is there a way to adjust my configuration so that these gaps do not appear when there is only one window?

Answer 1

Have a look at smartSpacing: (see Xmonad Spacing Docs)

Surrounds all windows with blank space, except when the window is the only visible window on the current workspace.

I.e., changing

tiled = spacing 5 $ Tall nmaster delta ratio

to

tiled = smartSpacing 5 $ Tall nmaster delta ratio

should to the trick.
