XMonad.Layout.Spacing

Add a configurable amount of space around windows.

Note: For space/gaps along edges of the screen see XMonad.Layout.Gaps.

Usage

You can use this module by importing it into your xmonad.hs file:

import XMonad.Layout.Spacing

and, for example, modifying your layoutHook as follows:

main :: IO ()
main = xmonad $ def
  { layoutHook = spacingWithEdge 10 $ myLayoutHook
  }

myLayoutHook = Full ||| ...

The above would add a 10 pixel gap around windows on all sides, as well as add the same amount of spacing around the edges of the screen. If you only want to add spacing around windows, you can use spacing instead.

There is also the spacingRaw command, for more fine-grained control. For example:

layoutHook = spacingRaw True (Border 0 10 10 10) True (Border 10 10 10 10) True
           $ myLayoutHook

Breaking this down, the above would do the following:

• True: Enable the smartBorder to not apply borders when there is only one window.
• (Border 0 10 10 10): Add a screenBorder of 10 pixels in every direction but the top.
• True: Enable the screenBorder.
• (Border 10 10 10 10): Add a windowBorder of 10 pixels in every direction.
• True: Enable the windowBorder.

Warning: If you also use the avoidStruts layout modifier, it must come before any of these modifiers. See the documentation of avoidStruts for details.

data Spacing a

A LayoutModifier providing customizable screen and window borders. Borders are clamped to [0,Infinity] before being applied.

-> l a

-> ModifiedLayout Spacing l a

Generate the ModifiedLayout, exposing all initial state of Spacing.

spacing :: Int -> l a -> ModifiedLayout Spacing l a

Surround all windows by a certain number of pixels of blank space. See spacingRaw.

spacingWithEdge :: Int -> l a -> ModifiedLayout Spacing l a

Surround all windows by a certain number of pixels of blank space, and additionally adds the same amount of spacing around the edge of the screen. See spacingRaw.

smartSpacing :: Int -> l a -> ModifiedLayout Spacing l a

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

smartSpacingWithEdge :: Int -> l a -> ModifiedLayout Spacing l a

Surrounds all windows with blank space, and adds the same amount of spacing around the edge of the screen, except when the window is the only visible window on the current workspace. See spacingRaw.
