* Info

This is my XMonad config. It's heavily based on Derek Taylor's config from DTOS.

The notable things I changed are noted in their specific sections.

* Window Management and Layouts

** Border Width and Spacing
#+begin_src haskell
myBorderWidth :: Dimension
myBorderWidth = 2

windowCount :: X (Maybe String)
windowCount = gets $ Just . show . length . W.integrate' . W.stack . W.workspace . W.current . windowset

--Makes setting the spacingRaw simpler to write. The spacingRaw module adds a configurable amount of space around windows.
mySpacing :: Integer -> l a -> XMonad.Layout.LayoutModifier.ModifiedLayout Spacing l a
mySpacing i = spacingRaw False (Border i i i i) True (Border i i i i) True
#+end_src


** Layouts
- limitWindows n sets maximum number of windows displayed for layout.
- mySpacing n sets the gap size around the windows.

#+begin_src haskell


tall     = renamed [Replace "tall"]
           $ smartBorders

tabs     = renamed [Replace "tabs"]
           -- I cannot add spacing to this layout because it will
           -- add spacing between window and tabs which looks bad.
          $ tabbed shrinkText myTabTheme
#+end_src

** Theming for tabs (sub)layout
#+begin_src haskell


myTabTheme = def { fontName            = "xft:Iosevka-9"
                 , activeColor         = color15
                 , inactiveColor       = colorBack
                 , activeBorderColor   = color15

                 , activeTextColor     = colorBack
                 , inactiveTextColor   = colorFore }
#+end_src


** Clickable workspaces in XMobar
#+begin_src haskell
mySB = statusBarProp "xmobar" (clickablePP xmobarPP)
#+end_src

** Workspace definitions

#+begin_src haskell
myWorkspaces =  ["1", "2", "3", "4", "5", "6", "7", "8", "9",
                 "e",
                 "w", "g", "d", "b", "j", "f", "o", "u",
                 "r", "s", "t", "h", "v", "y", "n", "a", "i", "l",
                 "x", "c", "m", "k", "q", "z", "p"
                ]

myWorkspaceIndices = M.fromList $ zipWith (,) myWorkspaces [1..] -- (,) == \x y -> (x,y)

clickable ws = "<action=xdotool key super+"++show i++">"++ws++"</action>"
    where i = fromJust $ M.lookup ws myWorkspaceIndices
#+end_src

** Manage Hook
#+begin_src haskell
myManageHook = manageSpawn <> composeAll
  [ className =? "confirm"         --> doFloat
  , className =? "file_progress"   --> doFloat
  , className =? "dialog"          --> doFloat
  , className =? "download"        --> doFloat
  , className =? "error"           --> doFloat
  , className =? "Gimp"            --> doFloat
  , className =? "notification"    --> doFloat
  , className =? "pinentry-gtk-2"  --> doFloat
  , className =? "splash"          --> doFloat
  , className =? "toolbar"         --> doFloat
  , className =? "zoom"            --> doFloat
  , className =? "Yad"             --> doCenterFloat
  , (className =? "firefox" <&&> resource =? "Dialog") --> doFloat  -- Float Firefox Dialog
  , isFullscreen -->  doFullFloat
  ]
#+end_src
** Startup Hook

Set the WMName and session type so applications which check for it don't bug out.
*** Settings applied on login
#+begin_src haskell
myStartupHook = do
  setWMName "LG3D"
  spawnOnce "lxsession"
#+end_src
**** Keyboard layout
I'm Polish, so I type on a Polish layout. I also extensively use the compose key, so I have it handy.
#+begin_src haskell
  spawnOnce "setxkbmap -model pc104 -layout pl -option compose:rctrl"
#+end_src
**** Mount encrypted container
#+begin_src haskell
  spawnOnce "gocryptfs ~/.bajsicki enc --extpass lxqt-openssh-askpass"
#+end_src
**** Wallpaper
Randomize wallpaper. Requires /feh/. You can change the path to any directory with wallpapers for consistent variety.
#+begin_src haskell
  spawnOnce "feh --randomize --bg-fill /usr/share/backgrounds/archlinux/*"
#+end_src
**** Trayer
Trayer is a system tray, which works well with XMobar. This restarts it every time XMonad is reinitialized to avoid weirdness.
#+begin_src haskell
  spawn "killall trayer"  -- kill current trayer on each
  spawn ("sleep 2 && trayer --edge top --align right --widthtype request --padding 6 --SetDockType true --SetPartialStrut true --expand true --monitor 1 --transparent true --alpha 0 " ++ colorTrayer ++ " --height 20")
#+end_src

**** Daemons
***** Dunst
Dunst for notifications.
#+begin_src haskell
  spawnOnce "dunst"
#+end_src
***** Activity Watch
I like looking back on the way I spend my time every once in a while. Local time tracking is really helpful, so I run AW in the background.
#+begin_src haskell
  spawnOnce "aw-server"
  spawnOnce "aw-watcher-afk"
  spawnOnce "aw-watcher-window"
  spawnOnce "poetry run aw-watcher-spotify"
#+end_src
***** Emacs
Emacs daemon for emacsclient.
#+begin_src haskell
  spawnOnce "/usr/bin/emacs --daemon"
#+end_src
*** Startup applications
#+begin_src haskell
  spawnOn "1" "firefox-developer-edition"
  spawnOn "2" "evolution"
  spawnOn "9" "steam"
  spawnOn "3" "discord"
  spawnOn "6" "google-chrome-stable"
  spawnOn "e" "/usr/bin/emacsclient"
  spawnOn "j" "keepassxc"
#+end_src
* Main XMonad loop

#+begin_src haskell
main :: IO ()

#+end_src
** XMobar
Launching three instances of xmobar on their monitors.
#+begin_src haskell
  xmproc0 <- spawnPipe ("xmobar -x 0 $HOME/.config/xmobar/tomorrow-night-xmobarrc")
  xmproc1 <- spawnPipe ("xmobar -x 1 $HOME/.config/xmobar/tomorrow-night-xmobarrc")

#+begin_src haskell
  xmonad $ ewmh $ docks $ def

#+end_src
*** handleEventHook
This lets alacritty be swallowed when it opens a GUI application.
#+begin_src haskell

#+end_src
*** logHook
Define logHook. ppOutput streams into the three instances of XMobar.
#+begin_src haskell
    , logHook = dynamicLogWithPP xmobarPP
        { ppOutput = \x -> hPutStrLn xmproc0 x
                        >> hPutStrLn xmproc1 x
                        >> hPutStrLn xmproc2 x
#+end_src
**** Colors/ clicks
#+begin_src haskell
        , ppCurrent = xmobarColor color06 "" . wrap
                      ("<box type=Bottom width=2 mb=1 color=" ++ color06 ++ ">") "</box>"

#+end_src

#+begin_src haskell

        } >> updatePointer (0.5, 0.5) (0.0, 0.0) }

* Keybinds
** Workspaces
This is the bulk of my changes. I use /a lot/ of workspaces.
They're all under two chords. M-s /shows/ a workspace, and M-t /throws/ a window to a workspace. Easy mnemonics, yay.

This lets me 'collect' windows into a tiled group if it starts getting crowded on the screen.

** XMonad and apps
Notes: I use a ZSA Moonlander so a lot of the 4-5 key sequences are actually just two keys.
