Like the old xinerama workspace comparison, but order by physical location just like X.A.PhysicalScreens. Useful if using xinerama sort for statusbar together with physicalscreens.
This patch will allow the user to split the currently focused screen instead of all screens together. This is usefull for multiscreen users who have functioning xinerama, but wish to split one of the screens.
Remove redundant import to supress warning, did some refactoring to use xmonad internal things to find screens instead of using X11-stuff. Also added ability to cycle between screens in physical order.
This patch adds a way go up through X.Prompt's history using
only those entries that start with the current input, similar
to zsh's `history-search-backward'.
doesDirectoryExist returns True if given an empty string using ghc <= 6.10.4.
This causes getDirectoryContents to raise an exception and X.P.Shell does not
render. This is only an issue if you have an empty string in your PATH.
Using ghc == 6.12.1, doesDirectoryExist returns False given an empty string, so
this should not be an issue in the future.
The problem was that certain layouts keep their "world" state in their value,
which was thrown away and forgotten after ReleaseResources during toggle.
In particular, decorated layouts store some X11 handles in them and
allocate/deallocate it as appropriate. If any modification to their state is
ignored, they may try to deallocate already deallocated memory, which results
in a crash somewhere inside Xlib.
This patch makes Transformers reversible so that nothing is ever ignored. As a
side effect, layout transformers now do receive messages and messages for the
base layout do not need the undo/reapply cycle -- we just pass messages to the
current transformed layout and unapply the transformer when needed.
(This, however, doesn't mean that the base layout is not asked to release
resources on a transformer change -- we still need the transformer to release
its resources and there's no way to do this without asking the base layout as
well.)
