# Usage

Here is an example config:

    import XMonad
    import XMonad.Actions.WorkspaceCursors
    import XMonad.Util.EZConfig
    import qualified XMonad.StackSet as W

    main = xmonad conf

    conf = additionalKeysP def
           { layoutHook = workspaceCursors myCursors $ layoutHook def
           , workspaces = toList myCursors } $
           [("M-"++shift++control++[k], f direction depth)
             | (f,shift) <- zip [modifyLayer,shiftModifyLayer] ["","S-"]
             , (direction,control) <- zip [W.focusUp',W.focusDown'] ["C-",""]
             , (depth,k) <- zip (reverse [1..focusDepth myCursors]) "asdf"]
           ++ moreKeybindings

    moreKeybindings = []

    myCursors = makeCursors $ map (map (\x -> [x])) [ "1234", "abc", "xyz"]
    -- myCursors = makeCursors [["wsA","wsB","wsC"],["-alpha-","-beta-","-gamma-"],["x","y"]]

focusDepth :: Cursors t -> Int #

makeCursors :: [[String]] -> Cursors String #

makeCursors requires a nonempty string, and each sublist must be nonempty

toList :: IsList l => l -> [Item l] #

The `toList` function extracts a list of `Item l` from the structure `l`. It should satisfy fromList . toList = id.

workspaceCursors :: Cursors String -> l a -> ModifiedLayout WorkspaceCursors l a #

The state is stored in the `WorkspaceCursors` layout modifier. Put this as your outermost modifier, unless you want different cursors at different times (using XMonad.Layout.MultiToggle)

getFocus :: Cursors b -> b #

# Modifying the focus

modifyLayer :: (Stack (Cursors String) -> Stack (Cursors String)) -> Int -> X () #

`modifyLayer` is used to change the focus at a given depth

modifyLayer' :: (Stack (Cursors String) -> X (Stack (Cursors String))) -> Int -> X () #

example usages are `shiftLayer` and `shiftModifyLayer`

shiftModifyLayer :: (Stack (Cursors String) -> Stack (Cursors WorkspaceId)) -> Int -> X () #

`shiftModifyLayer` is the same as `modifyLayer`, but also shifts the currently focused window to the new workspace

shiftLayer :: (Stack (Cursors String) -> Stack (Cursors WorkspaceId)) -> Int -> X () #

`shiftLayer` is the same as `shiftModifyLayer`, but the focus remains on the current workspace.

# Functions to pass to `modifyLayer`

focusNth' :: Int -> Stack a -> Stack a #

noWrapUp :: Stack t -> Stack t #

non-wrapping version of `focusUp'`

noWrapDown :: Stack t -> Stack t #

non-wrapping version of `focusDown'`

# Todo

- Find and document how to raise the allowable length of arguments: restoring xmonad's state results in: `xmonad: executeFile: resource exhausted (Argument list too long)` when you specify more than about 50 workspaces. Or change it such that workspaces are created when you try to view it.
- Function for pretty printing for XMonad.Hooks.StatusBar.PP that groups workspaces by common prefixes
- Examples of adding workspaces to the cursors, having them appear multiple times for being able to show jumping to some n'th multiple workspace
