-- Makes xmonad use the

-- hints to tell panel applications about its workspaces and the windows

-- $usage
-- You can use this module with the following in your @xmonad.hs@:
--
-- > import XMonad
-- > import XMonad.Hooks.EwmhDesktops
-- >
-- > main = xmonad $ … . ewmhFullscreen . ewmh . … $ def{…}
--
-- or, if fullscreen handling is not desired, just
--
-- > main = xmonad $ … . ewmh . … $ def{…}
--
-- You may also be interested in 'XMonad.Hooks.ManageDocks.docks' and
-- 'XMonad.Hooks.UrgencyHook.withUrgencyHook', which provide support for other
-- parts of the
-- <https://specifications.freedesktop.org/wm-spec/latest/ EWMH specification>.

-- | Add EWMH support for workspaces (virtual desktops) to the given
-- 'XConfig'.  See above for an example.

-- $customSort
-- The list of workspaces exposed to EWMH pagers (like
-- <https://github.com/taffybar/taffybar taffybar> and
-- <https://github.com/polybar/polybar polybar>) and clients (such as
-- <http://tomas.styblo.name/wmctrl/ wmctrl> and
-- <https://github.com/jordansissel/xdotool/ xdotool>) may be sorted and/or
-- filtered via a user-defined function.
--
-- To show visible workspaces first, one may switch to a Xinerama-aware
-- sorting function:
--
-- > import XMonad.Util.WorkspaceCompare
-- >
-- > mySort = getSortByXineramaRule
-- > main = xmonad $ … . setEwmhWorkspaceSort mySort . ewmh . … $ def{…}
--
-- Another useful example is not exposing the hidden scratchpad workspace:
--
-- > import XMonad.Util.NamedScratchpad
-- > import XMonad.Util.WorkspaceCompare
-- >
-- > myFilter = filterOutWs [scratchpadWorkspaceTag]
-- > main = xmonad $ … . addEwmhWorkspaceSort (pure myFilter) . ewmh . … $ def{…}

-- | Add (compose after) an arbitrary user-specified function to sort/filter
-- the workspace list. The default/initial function is 'getSortByIndex'. This
-- can be used to e.g. filter out scratchpad workspaces. Workspaces /must not/
-- be renamed here.

-- $customRename
-- The workspace names exposed to EWMH pagers and other clients (e.g.
-- <https://arbtt.nomeata.de/ arbtt>) may be altered using a similar
-- interface to 'XMonad.Hooks.StatusBar.PP.ppRename'. To configure workspace
-- renaming, use 'addEwmhWorkspaceRename'.
--
-- As an example, to expose workspaces uppercased:
--
-- > import Data.Char
-- >
-- > myRename :: String -> WindowSpace -> String
-- > myRename s _w = map toUpper s
-- >
-- > main = xmonad $ … . addEwmhWorkspaceRename (pure myRename) . ewmh . … $ def{…}
--
-- Some modules like "XMonad.Actions.WorkspaceNames" provide ready-made
-- integrations:
--
-- > import XMonad.Actions.WorkspaceNames
-- >
-- > main = xmonad $ … . workspaceNamesEwmh . ewmh . … $ def{…}
--
-- The above ensures workspace names are exposed through EWMH.

-- | Add (compose after) an arbitrary user-specified function to rename each
-- workspace. This works just like 'XMonad.Hooks.StatusBar.PP.ppRename': the
-- @WindowSpace -> …@ acts as a Reader monad. Useful with
-- "XMonad.Actions.WorkspaceNames", "XMonad.Layout.IndependentScreens",
-- "XMonad.Hooks.DynamicIcons".

-- $customActivate
-- When a client sends a @_NET_ACTIVE_WINDOW@ request to activate a window, by
-- default that window is activated by invoking the 'doFocus' 'ManageHook'.
-- <https://specifications.freedesktop.org/wm-spec/1.5/ar01s03.html#idm45623294083744 The EWMH specification suggests>
-- that a window manager may instead just mark the window as urgent, and this
-- can be achieved using the following:
--
-- > import XMonad.Hooks.UrgencyHook
-- >
-- > main = xmonad $ … . setEwmhActivateHook doAskUrgent . ewmh . … $ def{…}
--
-- One may also wish to ignore activation requests from certain applications
-- entirely:
--
-- > import XMonad.Hooks.ManageHelpers
-- >
-- > myActivateHook :: ManageHook
-- > myActivateHook =
-- >   className /=? "Google-chrome" <&&> className /=? "google-chrome" --> doFocus
-- >
-- > main = xmonad $ … . setEwmhActivateHook myActivateHook . ewmh . … $ def{…}
--
-- Arbitrarily complex hooks can be used. This last example marks Chrome
-- windows as urgent and focuses everything else:
--
-- > myActivateHook :: ManageHook
-- > myActivateHook = composeOne
-- >   [ className =? "Google-chrome" <||> className =? "google-chrome" -?> doAskUrgent
-- >   , pure True -?> doFocus ]
--
-- See "XMonad.ManageHook", "XMonad.Hooks.ManageHelpers" and "XMonad.Hooks.Focus"
-- for functions that can be useful here.

-- | Set (replace) the hook which is invoked when a client sends a
-- @_NET_ACTIVE_WINDOW@ request to activate a window. The default is 'doFocus'
-- which focuses the window immediately, switching workspace if necessary.
-- 'XMonad.Hooks.UrgencyHook.doAskUrgent' is a less intrusive alternative.
--
-- More complex hooks can be constructed using combinators from
-- "XMonad.ManageHook", "XMonad.Hooks.ManageHelpers" and "XMonad.Hooks.Focus".

-- $customFullscreen
-- When a client sends a @_NET_WM_STATE@ request to add\/remove\/toggle the
-- @_NET_WM_STATE_FULLSCREEN@ state, 'ewmhFullscreen' uses a pair of hooks to
-- make the window fullscreen and revert its state. The default hooks are
-- stateless: windows are fullscreened by turning them into fullscreen floats,
-- and reverted by sinking them into the tiling layer. This behaviour can be
-- configured by supplying a pair of 'ManageHook's to 'setEwmhFullscreenHooks'.
--
-- See "XMonad.Actions.ToggleFullFloat" for a pair of hooks that store the
-- original state of floating windows.

-- | Set (replace) the hooks invoked when clients ask to add/remove the
-- $_NET_WM_STATE_FULLSCREEN@ state. The defaults are 'doFullFloat' and
-- 'doSink'.

-- $customManageDesktopViewport
-- Setting @_NET_DESKTOP_VIEWPORT@ is typically desired but can lead to a
-- confusing workspace list in polybar, where this information is used to
-- re-group the workspaces by monitor. See
-- <https://github.com/polybar/polybar/issues/2603 polybar#2603>.
--
-- To avoid this, you can use:
--
-- > main = xmonad $ … . disableEwmhManageDesktopViewport . ewmh . … $ def{…}
--
-- Note that if you apply this configuration in an already running environment,
-- the property may remain at its previous value. It can be removed by running:
--
-- > xprop -root -remove _NET_DESKTOP_VIEWPORT
--
-- Which should immediately fix your bar.
