XMonad.Layout.Mosaic

Based on MosaicAlt, but aspect ratio messages always change the aspect ratios, and rearranging the window stack changes the window sizes.

Usage

You can use this module with the following in your ~/.xmonad/xmonad.hs:

import XMonad.Layout.Mosaic

Then edit your layoutHook by adding the Mosaic layout:

myLayout = mosaic 2 [3,2] ||| Full ||| etc..
main = xmonad $ def { layoutHook = myLayout }

Unfortunately, infinite lists break serialization, so don't use them. And if the list is too short, it is extended with ++ repeat 1, which covers the main use case.

To change the choice in aspect ratio and the relative sizes of windows, add to your keybindings:

, ((modm, xK_a), sendMessage Taller)
, ((modm, xK_z), sendMessage Wider)

, ((modm, xK_r), sendMessage Reset)

Message Aspect

Defined in XMonad.Layout.Mosaic

mosaic :: Rational -> [Rational] -> Mosaic a

The relative magnitudes (the sign is ignored) of the rational numbers in the second argument determine the relative areas that the windows receive. The first number represents the size of the master window, the second is for the next window in the stack, and so on.

The list is extended with ++ repeat 1, so mosaic 1.5 [] is like a resizable grid.

The first parameter is the multiplicative factor to use when responding to the Expand message.

changeMaster :: (Rational -> Rational) -> X ()

These sample functions are meant to be applied to the list of window sizes through the SlopeMod message.

changeFocused :: (Rational -> Rational) -> X ()

Apply a function to the Rational that represents the currently focused window.

Expand and Shrink messages are responded to with changeFocused (*delta) or changeFocused (delta/) where delta is the first argument to mosaic.

This is exported because other functions (ex. const 1, (+1)) may be useful to apply to the current area.
