Description

Provides bindings to cycle forward or backward through the list of workspaces, to move windows between workspaces, and to cycle between screens. More general combinators provide ways to cycle through workspaces in various orders, to only cycle through some subset of workspaces, and to cycle by more than one workspace at a time.

Note that this module now subsumes the functionality of the former `XMonad.Actions.RotView`. Former users of `rotView` can simply replace `rotView True` with `moveTo Next NonEmptyWS`, and so on.

If you want to exactly replicate the action of `rotView` (cycling through workspace in order lexicographically by tag, instead of in the order specified in the config), it can be implemented as:

    rotView b  = do t <- findWorkspace getSortByTag (bToDir b) NonEmptyWS 1
                    windows . greedyView $ t
      where bToDir True  = Next
            bToDir False = Prev

# Usage

You can use this module with the following in your `~/.xmonad/xmonad.hs` file:

    import XMonad.Actions.CycleWS

    -- a basic CycleWS setup

      , ((modm,               xK_Down),  nextWS)
      , ((modm,               xK_Up),    prevWS)
      , ((modm .|. shiftMask, xK_Down),  shiftToNext)
      , ((modm .|. shiftMask, xK_Up),    shiftToPrev)
      , ((modm,               xK_Right), nextScreen)
      , ((modm,               xK_Left),  prevScreen)
      , ((modm .|. shiftMask, xK_Right), shiftNextScreen)
      , ((modm .|. shiftMask, xK_Left),  shiftPrevScreen)
      , ((modm,               xK_z),     toggleWS)

If you want to follow the moved window, you can use both actions:

      , ((modm .|. shiftMask, xK_Down), shiftToNext >> nextWS)
      , ((modm .|. shiftMask, xK_Up),   shiftToPrev >> prevWS)

You can also get fancier with `moveTo`, `shiftTo`, and `findWorkspace`. For example:

      , ((modm     , xK_f), moveTo Next EmptyWS)  -- find a free workspace
      , ((modm .|. controlMask, xK_Right),        -- a crazy keybinding!
            do t <- findWorkspace getSortByXineramaRule Next NonEmptyWS 2
               windows . view $ t                                         )

For detailed instructions on editing your key bindings, see XMonad.Doc.Extending.

When using the toggle functions, in order to ensure that the workspace to which you switch is the previously viewed workspace, use the `logHook` in XMonad.Hooks.WorkspaceHistory.

# Moving between workspaces

The following commands for moving the view and windows between workspaces are somewhat inflexible, but are very simple and probably Do The Right Thing for most users.

All of the commands in this section cycle through workspaces in the order in which they are given in your config.

nextWS :: X () Source #

Switch to the next workspace.

prevWS :: X () Source #

Switch to the previous workspace.

shiftToNext :: X () Source #

Move the focused window to the next workspace.

shiftToPrev :: X () Source #

Move the focused window to the previous workspace.

# Toggling the previous workspace

toggleWS :: X () Source #

Toggle to the workspace displayed previously.

toggleWS' :: [WorkspaceId] -> X () Source #

Toggle to the previous workspace while excluding some workspaces.

    -- Ignore the scratchpad workspace while toggling:
    ("M-b", toggleWS' ["NSP"])

toggleOrView :: WorkspaceId -> X () Source #

`greedyView` a workspace, or if already there, view the previously displayed workspace ala weechat. Change `greedyView` to `toggleOrView` in your workspace bindings as in the `view` faq at http://haskell.org/haskellwiki/Xmonad/Frequently_asked_questions. For more flexibility see `toggleOrDoSkip`.

# Moving between screens (xinerama)

nextScreen :: X () Source #

View next screen

prevScreen :: X () Source #

View prev screen

shiftNextScreen :: X () Source #

Move focused window to workspace on next screen

shiftPrevScreen :: X () Source #

Move focused window to workspace on prev screen

swapNextScreen :: X () Source #

Swap current screen with next screen

swapPrevScreen :: X () Source #

Swap current screen with previous screen

# Moving between workspaces, take two!

A few more general commands are also provided, which allow cycling through subsets of workspaces.

For example,

      moveTo Next EmptyWS

will move to the first available workspace with no windows, and

      shiftTo Prev (WSIs $ return (('p' `elem`) . tag))

will move the focused window backwards to the first workspace containing the letter `p` in its name. =)

data Direction1D Source #

data WSType Source #

What type of workspaces should be included in the cycle?

Constructors

EmptyWS | cycle through empty workspaces
NonEmptyWS | cycle through non-empty workspaces
HiddenWS | cycle through non-visible workspaces
HiddenNonEmptyWS | cycle through non-empty non-visible workspaces
HiddenEmptyWS | cycle through empty non-visible workspaces
AnyWS | cycle through all workspaces
WSTagGroup Char | cycle through workspaces in the same group, the group name is all characters up to the first separator character or the end of the tag
WSIs (X (WindowSpace -> Bool)) | cycle through workspaces satisfying an arbitrary predicate

shiftTo :: Direction1D -> WSType -> X () Source #

Move the currently focused window to the next workspace in the given direction that satisfies the given condition.

moveTo :: Direction1D -> WSType -> X () Source #

View the next workspace in the given direction that satisfies the given condition.

doTo :: Direction1D -> WSType -> X WorkspaceSort -> (WorkspaceId -> X ()) -> X () Source #

Using the given sort, find the next workspace in the given direction of the given type, and perform the given action on it.

# The mother-combinator

findWorkspace :: X WorkspaceSort -> Direction1D -> WSType -> Int -> X WorkspaceId Source #

Given a function `s` to sort workspaces, a direction `dir`, a predicate `p` on workspaces, and an integer `n`, find the tag of the workspace which is `n` away from the current workspace in direction `dir` (wrapping around if necessary), among those workspaces, sorted by `s`, which satisfy `p`.

For some useful workspace sorting functions, see XMonad.Util.WorkspaceCompare.

For ideas of what to do with a workspace tag once obtained, note that `moveTo` and `shiftTo` are implemented by applying `(>>= (windows . greedyView))` and `(>>= (windows . shift))`, respectively, to the output of `findWorkspace`.

toggleOrDoSkip :: [WorkspaceId] -> (WorkspaceId -> WindowSet -> WindowSet) -> WorkspaceId -> X () Source #

Allows ignoring listed workspace tags (such as scratchpad's "NSP"), and running other actions such as view, shift, etc. For example:

    import qualified XMonad.StackSet as W
    import XMonad.Actions.CycleWS

    -- toggleOrView for people who prefer view to greedyView
    toggleOrView' = toggleOrDoSkip [] W.view

    -- toggleOrView ignoring scratchpad and named scratchpad workspace
    toggleOrViewNoSP = toggleOrDoSkip ["NSP"] W.greedyView

skipTags :: Eq i => [Workspace i l a] -> [i] -> [Workspace i l a] Source #

List difference (`\\`) for workspaces and tags. Removes workspaces matching listed tags from the given workspace list.

screenBy :: Int -> X ScreenId Source #

Get the `ScreenId` d places over. Example usage is a variation of the the default screen keybindings:

        -- mod-{w,e}, Switch to previous/next Xinerama screen
        -- mod-shift-{w,e}, Move client to previous/next Xinerama screen
        --
        [((m .|. modm, key), sc >>= screenWorkspace >>= flip whenJust (windows . f))
            | (key, sc) <- zip [xK_w, xK_e] [(screenBy (-1)),(screenBy 1)]
            , (f, m) <- [(W.view, 0), (W.shift, shiftMask)]]
