* Mouse bindings
Mouse bindings: default actions bound to mouse events
#+begin_src haskell

    -- mod-button1, Set the window to floating mode and move by dragging

                                       >> windows W.shiftMaster))
    ]
#+end_src
------------------------------------------------------------------------
* Layouts:

You can specify and transform your layouts by modifying these values.
If you change layout bindings be sure to use 'mod-shift-space' after
restarting (with 'mod-q') to reset your layout state to the new
defaults, as xmonad preserves your old layout settings by default.

The available layouts.  Note that each layout is separated by |||,
which denotes layout choice.

#+begin_src haskell
myLayout =  mySpacing $ avoidStruts ( tiled ||| Mirror tiled |||  noBorders Full ||| spiral (6/7) ||| ThreeCol 1 (3/100) (1/2))
  where
     -- default tiling algorithm partitions the screen into two panes
     tiled   = Tall nmaster delta ratio

     -- The default number of windows in the master pane
     nmaster = 1

     -- Default proportion of screen occupied by master pane
     ratio   = 1/2

     -- Percent of screen to increment by when resizing panes
     delta   = 3/100
#+end_src

* Window spacing (gaps)
sets the spacing of the windows.
#+begin_src haskell
mySpacing = spacingRaw False             -- Only for >1 window
                       -- The bottom edge seems to look narrower than it is
                       (Border 30 3 3 3) -- Size of screen edge gaps
                       True             -- Enable screen edge gaps
                       (Border 3 3 3 3) -- Size of window gaps
                       True             -- Enable window gaps
#+end_src


------------------------------------------------------------------------
* Window rules
Execute arbitrary actions and WindowSet manipulations when managing
a new window. You can use this to, for example, always float a
particular program, or have a client always appear on a particular
workspace.
To find the property name associated with a program, use
> xprop | grep WM_CLASS
and click on the client you're interested in.
To match on the WM_NAME, you can use 'title' in the same way that
'className' and 'resource' are used below.
#+begin_src haskell
myManageHook = composeAll
    [className =? "Gimp"           --> doFloat
    , className =? "Qalculate-gtk"     --> doFloat
    , className =? "Pavucontrol"    --> doFloat
    , className =? "Minecraft Launcher"         --> doShift "8"
    , className =? "YouTube Music"  --> doShift "9"
    , className =? "Thunar"         --> viewShift "5"
    , resource  =? "desktop_window" --> doIgnore
    , resource  =? "kdesktop"       --> doIgnore
    ]
    where viewShift = doF . liftM2 (.) W.greedyView W.shift
#+end_src


------------------------------------------------------------------------
* Event handling
EwmhDesktops users should change this to ewmhDesktopsEventHook
Defines a custom handler function for X Events. The function should
return (All True) if the default handler is to be run afterwards. To
combine event hooks use mappend or mconcat from Data.Monoid.
#+begin_src haskell
myEventHook = swallowEventHook (className =? "kitty" <||> className =? "Termite") (return True)
#+end_src

* Log Hooks
Status bars and logging
Perform an arbitrary action on each internal state change or X event.
See the 'XMonad.Hooks.DynamicLog' extension for examples.
#+begin_src haskell
myLogHook = do
  winset <- gets windowset
  title <- maybe (return "") (fmap show . getName) . W.peek $ winset
  let currWs = W.currentTag winset
  let wss = map W.tag $ W.workspaces winset
  let wsStr = join $ map (fmt currWs) $ sort' wss

  io $ appendFile "/tmp/.xmonad-title-log" (title ++ "\n")
  io $ appendFile "/tmp/.xmonad-workspace-log" (wsStr ++ "\n")

  where fmt currWs ws
          | currWs == ws = "[" ++ ws ++ "]"
          | otherwise    = " " ++ ws ++ " "
        sort' = sortBy (compare `on` (!! 0))
#+end_src

* Window swallowing with kitty
#+begin_src haskell
myHandleEventHook = swallowEventHook (className =? "kitty" <||> className =? "Termite") (return True)
#+end_src

* Start up applications
Perform an arbitrary action each time xmonad starts or is restarted
with mod-q.  Used by, e.g., XMonad.Layout.PerWorkspace to initialize
per-workspace layout choices.

By default, do nothing.
#+begin_src haskell
myStartupHook = do
        spawnOnce "dunst &"
        spawnOnce "pipewire & /usr/bin/pipewire-pulse & /usr/bin/pipewire-media-session &"
        spawnOnce "/home/$USER/.config/script/redshift.sh &"
        spawnOnce "xss-lock /home/$USER/.config/script/betterlockscreen.sh  &"
        spawnOnce "nextcloud --background &"
        spawnOnce "fcitx -d &"
        spawnOnce "copyq --start-server"
        spawnOnce "/usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1"
