XMonad.Actions.WorkspaceCursors

Like XMonad.Actions.Plane for an arbitrary number of dimensions.

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)

Instances

LayoutModifier WorkspaceCursors a

Defined in XMonad.Actions.WorkspaceCursors

Methods

modifyLayout :: LayoutClass l a => WorkspaceCursors a -> Workspace WorkspaceId (l a) a -> Rectangle -> X ([(a, Rectangle)], Maybe (l a))

modifyLayoutWithUpdate :: LayoutClass l a => WorkspaceCursors a -> Workspace WorkspaceId (l a) a -> Rectangle -> X (([(a, Rectangle)], Maybe (l a)), Maybe (WorkspaceCursors a))

handleMess :: WorkspaceCursors a -> SomeMessage -> X (Maybe (WorkspaceCursors a))

handleMessOrMaybeModifyIt :: WorkspaceCursors a -> SomeMessage -> X (Maybe (Either (WorkspaceCursors a) SomeMessage))

pureMess :: WorkspaceCursors a -> SomeMessage -> Maybe (WorkspaceCursors a)

redoLayout :: WorkspaceCursors a -> Rectangle -> Maybe (Stack a) -> [(a, Rectangle)] -> X ([(a, Rectangle)], Maybe (WorkspaceCursors a))

pureModifier :: WorkspaceCursors a -> Rectangle -> Maybe (Stack a) -> [(a, Rectangle)] -> ([(a, Rectangle)], Maybe (WorkspaceCursors a))

hook :: WorkspaceCursors a -> X ()

unhook :: WorkspaceCursors a -> X ()

modifierDescription :: WorkspaceCursors a -> String

modifyDescription :: LayoutClass l a => WorkspaceCursors a -> l a -> String

Read (WorkspaceCursors a)

Defined in XMonad.Actions.WorkspaceCursors

Methods

readsPrec :: Int -> ReadS (WorkspaceCursors a)

readList :: ReadS [WorkspaceCursors a]

readPrec :: ReadPrec (WorkspaceCursors a)

readListPrec :: ReadPrec [WorkspaceCursors a]

Show (WorkspaceCursors a)

Defined in XMonad.Actions.WorkspaceCursors

Methods

showsPrec :: Int -> WorkspaceCursors a -> ShowS

show :: WorkspaceCursors a -> String

showList :: [WorkspaceCursors a] -> ShowS

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
