-- 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.
|
|
--
|
|
-- Requires the 'directory' package

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