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.

Note this extension requires the directory package to be installed.

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

import XMonad.Layout.WorkspaceDir

Then edit your layoutHook by adding the Workspace layout modifier to some layout:

myLayout = workspaceDir "~" (Tall 1 (3/100) (1/2))  ||| Full ||| etc..
main = xmonad def { layoutHook = myLayout }

For more detailed instructions on editing the layoutHook see the tutorial and XMonad.Doc.Extending.

WorkspaceDir provides also a prompt. To use it you need to import XMonad.Prompt and add something like this to your key bindings:

 , ((modm .|. shiftMask, xK_x     ), changeDir def)

If you prefer a prompt with case-insensitive completion:

 , ((modm .|. shiftMask, xK_x     ),

changeDir def {complCaseSensitivity = CaseInSensitive})

For detailed instruction on editing the key binding see:
