* About This Config
#+CAPTION: XMonad Scrot
#+ATTR_HTML: :alt XMonad Scrot :title XMonad Scrot :align left 
[[https://gitlab.com/dwt1/dotfiles/-/raw/master/.screenshots/dotfiles05-thumb.png]]

Xmonad is a dynamically tiling X11 window manager that is written and
configured in Haskell. Official documentation: [[https://xmonad.org][https://xmonad.org]]

This is the xmonad configuration of Derek Taylor (DistroTube)
- My YouTube: [[http://www.youtube.com/c/DistroTube][http://www.youtube.com/c/DistroTube]]
- My GitLab:  [[http://www.gitlab.com/dwt1/][http://www.gitlab.com/dwt1/]]

Keep in mind, that my configs are purposely bloated with examples of
what you can do with xmonad. It is written more as a study guide rather
than a config that you should download and use.

* Imports
These are Haskell modules that we must import so that we can use their functions later in the config.

* Variables
It's nice to assign values to stuff that you will use more than once
in the config. Setting values for things like font, terminal and editor
means you only have to change the value here to make changes globally.

#+BEGIN_SRC haskell
myFont :: String
myFont = "xft:Mononoki Nerd Font:bold:size=9:antialias=true:hinting=true"

myModMask :: KeyMask
myModMask = mod4Mask       -- Sets modkey to super/windows key

myTerminal :: String
myTerminal = "alacritty"   -- Sets default terminal

myBrowser :: String
myBrowser = "qutebrowser "               -- Sets qutebrowser as browser for tree select
-- myBrowser = myTerminal ++ " -e lynx " -- Sets lynx as browser for tree select

myEditor :: String
myEditor = "emacsclient -c -a emacs "  -- Sets emacs as editor for tree select
-- myEditor = myTerminal ++ " -e vim "    -- Sets vim as editor for tree select

myBorderWidth :: Dimension
myBorderWidth = 2          -- Sets border width for windows

myNormColor :: String
myNormColor   = "#282c34"  -- Border color of normal windows

myFocusColor :: String
myFocusColor  = "#bbc5ff"  -- Border color of focused windows

altMask :: KeyMask
altMask = mod1Mask         -- Setting this for use in xprompts

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

* Autostart
These are commands we want XMonad to execute on startup, such as running a compositor, setting our wallpaper, starting the emacs daemon, and starting our system tray and the applications that belong in it.

#+BEGIN_SRC haskell
myStartupHook :: X ()
myStartupHook = do
          spawnOnce "nitrogen --restore &"
          spawnOnce "picom &"
          spawnOnce "nm-applet &"
          spawnOnce "volumeicon &"
          spawnOnce "trayer --edge top --align right --widthtype request --padding 6 --SetDockType true --SetPartialStrut true --expand true --monitor 1 --transparent true --alpha 0 --tint 0x282c34  --height 22 &"
          spawnOnce "/usr/bin/emacs --daemon &"
          -- spawnOnce "kak -d -s mysession &"
          setWMName "LG3D"
#+END_SRC

* Gridselect
GridSelect displays items (programs, open windows, etc.) in a 2D grid
and lets the user select from it with the cursor/hjkl keys or the mouse.

#+BEGIN_SRC haskell
myColorizer :: Window -> Bool -> X (String, String)
myColorizer = colorRangeFromClassName
                  (0x28,0x2c,0x34) -- lowest inactive bg
                  (0x28,0x2c,0x34) -- highest inactive bg
                  (0xc7,0x92,0xea) -- active bg
                  (0xc0,0xa7,0x9a) -- inactive fg
                  (0x28,0x2c,0x34) -- active fg

    , gs_originFractX = 0.5
    , gs_originFractY = 0.5
    , gs_font         = myFont
    }

spawnSelected' :: [(String, String)] -> X ()
spawnSelected' lst = gridselect conf lst >>= flip whenJust spawn
    where conf = def
                   { gs_cellheight   = 40
                   , gs_cellwidth    = 200

                   , gs_originFractY = 0.5
                   , gs_font         = myFont
                   }

myAppGrid = [ ("Audacity", "audacity")

                 ]
#+END_SRC

* Treeselect
TreeSelect displays your workspaces or actions in a Tree-like format.
You can select desired workspace/action with the cursor or hjkl keys.
My TreeSelect menu is rather large and includes a mixture of applications,
web bookmarks, configuration files and xmonad actions.

* Workspaces
My workspaces are clickable meaning that the mouse can be used to switch
workspaces. This requires xdotool. You need to use UnsafeStdInReader instead
of simply StdInReader in xmobar config so you can pass actions to it. Also,
you will notice I add <fn> tags to the clickable workspaces to select from
the additionalFonts that I have set in my xmobar configs.

#+BEGIN_SRC haskell
xmobarEscape :: String -> String
xmobarEscape = concatMap doubleLts
  where
        doubleLts '<' = "<<"
        doubleLts x   = [x]

myWorkspaces :: [String]
myWorkspaces = clickable . (map xmobarEscape)
               -- $ ["1", "2", "3", "4", "5", "6", "7", "8", "9"]
               $ ["dev", "www", "sys", "doc", "vbox", "chat", "mus", "vid", "gfx"]

        clickable l = [ "<action=xdotool key super+" ++ show (n) ++ "> " ++ ws ++ " </action>" |

                      let n = i ]
#+END_SRC

* Managehook
Sets some rules for certain programs. Examples include forcing certain
programs to always float, or to always appear on a certain workspace.
Forcing programs to a certain workspace with a doShift requires xdotool
if you are using clickable workspaces. You need the className or title
of the program. Use xprop to get this info.

#+BEGIN_SRC haskell

* Loghook
Sets opacity for inactive (unfocused) windows. I prefer to not use
this feature so I've set opacity to 1.0. If you want opacity, set
this to a value of less than 1 (such as 0.9 for 90% opacity).

* Keybindings
