--
-- Maintainer : Tomas Janousek <tomi@nomi.cz>
-- Stability : experimental
-- Portability : unportable
--
-- Provides bindings to rename workspaces, show these names in DynamicLog and
-- swap workspaces along with their names. These names survive restart.
-- Together with "XMonad.Layout.WorkspaceDir" this provides for a fully
-- dynamic topic space workflow.

-- $usage
-- You can use this module with the following in your @~\/.xmonad\/xmonad.hs@ file:
--
-- > import XMonad.Actions.WorkspaceNames
--
-- Then add keybindings like the following:
--
-- > , ((modm .|. shiftMask, xK_r ), renameWorkspace def)
--
-- and apply workspaceNamesPP to your DynamicLog pretty-printer:
--
-- > myLogHook =
-- > workspaceNamesPP xmobarPP >>= dynamicLogString >>= xmonadPropLog
--
-- We also provide a modification of "XMonad.Actions.SwapWorkspaces"\'s
-- functionality, which may be used this way:
--
-- > , ((modMask .|. shiftMask, xK_Left ), swapTo Prev)
-- > , ((modMask .|. shiftMask, xK_Right ), swapTo Next)
--
-- > [((modm .|. controlMask, k), swapWithCurrent i)
-- > | (i, k) <- zip workspaces [xK_1 ..]]
--
-- For detailed instructions on editing your key bindings, see
-- "XMonad.Doc.Extending#Editing_key_bindings".
