-- WorkspaceDir is an extension to set the current directory in a workspace.
--
-- Actually, it sets the current directory in a layout, since there's no way I
-- know of to attach a behavior to a workspace. This means that any terminals
-- (or other programs) pulled up in that workspace (with that layout) will
-- execute in that working directory. Sort of handy, I think.

-- $usage
-- You can use this module with the following in your Config.hs file:
--
-- > import XMonadContrib.WorkspaceDir
-- >
-- > defaultLayouts = map (workspaceDir "~") [ tiled, ... ]
--
-- In keybindings:
--
-- > , ((modMask .|. shiftMask, xK_x ), changeDir defaultXPConfig)
-- %import XMonadContrib.WorkspaceDir
-- %keybind , ((modMask .|. shiftMask, xK_x ), changeDir defaultXPConfig)
-- %layout -- prepend 'map (workspaceDir "~")' to defaultLayouts definition above,
-- %layout -- just before the list, like the following (don't uncomment next line):
-- %layout -- defaultLayouts = map (workspaceDir "~") [ tiled, ... ]
