Terminal

The preferred terminal program, which is used in a binding below and by certain contrib modules.

myTerminal      = "alacritty"

Window Behavior & Appearance

Mouse Focus

Whether focus follows the mouse pointer.

myFocusFollowsMouse :: Bool
myFocusFollowsMouse = True

Whether clicking on a window to focus also passes the click to the window

myClickJustFocuses :: Bool
myClickJustFocuses = False

Window Border Size

Width of the window border in pixels.

myBorderWidth   = 2

Window Border Colors

Border colors for unfocused and focused windows, respectively.

myNormalBorderColor  = "#4D4D4D"
myFocusedBorderColor = "#BD93F9"

Workspaces

The default number of workspaces (virtual screens) and their names. By default we use numeric strings, but any string may be used as a workspace name. The number of workspaces is determined by the length of this list.

A tagging example:

workspaces = ["web", "irc", "code" ] ++ map show [4..9]
workspaces = ["\xf868\x2081", "\xfd2c\x2082", "\xf2ce\x2083", "\xf1bc\x2084", "\xfa9e\x2085", "\xe795\x2086", "\xf667\x2087", "\xf11b\x2088", "\xf085\x2089"]
workspaces = ["1:\xf868", "2:\xfd2c", "3:\xf2ce", "4:\xf1bc", "5:\xfa9e", "6:\xe795", "7:\xf667", "8:\xf11b", "9:\xf085"]

myWorkspaces    = ["1", "2", "3", "4", "5", "6", "7", "8", "9"]

Keybindings

Modifier Key

modMask lets you specify which modkey you want to use. The default is mod1Mask ("left alt"). You may also consider using mod3Mask ("right alt"), which does not conflict with emacs keybindings. The "windows key" is usually mod4Mask.

myModMask       = mod4Mask

Default Keybindings

These default keybindings are left for reference, but are not actually used in my config. desktopConfig automatically uses the default keybindings shown below. I am overwriting some of these in the /sravan/xmonad/src/branch/master/%2AEZConfig%20Keybindings

Mouse Bindings

Mouse bindings: default actions bound to mouse events

myMouseBindings (XConfig {XMonad.modMask = modm}) = M.fromList $

    -- mod-button1, Set the window to floating mode and move by dragging
    [ ((modm, button1), (\w -> focus w >> mouseMoveWindow w
                                       >> windows W.shiftMaster))

    -- mod-button2, Raise the window to the top of the stack
    , ((modm, button2), (\w -> focus w >> windows W.shiftMaster))

    -- mod-button3, Set the window to floating mode and resize by dragging
    , ((modm, button3), (\w -> focus w >> mouseResizeWindow w
                                       >> windows W.shiftMaster))

    -- you may also bind events to the mouse scroll wheel (button4 and button5)
    ]

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.

myLayout =
  -- remove borders on floating windows that cover the whole screen
  lessBorders OnlyScreenFloat
  -- avoid struts (status bar)
  $ avoidStruts ( tiled ||| grid ||| monocle )
  where
     -- Gaps around and between windows
     -- Changes only seem to apply if I log out then in again
     -- Dimensions are given as (Border top bottom right left)
     mySpacing = spacingRaw False                -- Only for >1 window
                            -- The bottom edge seems to look narrower than it is
                            (Border 15 15 15 15) -- Size of screen edge gaps
                            True                 -- Enable screen edge gaps
                            (Border 10 10 10 10) -- Size of window gaps
                            True                 -- Enable window gaps

     -- default tiling algorithm partitions the screen into two panes
     nmaster = 1
     delta = 3/100
     tiled_ratio = 1/2
     tiled = mySpacing $ ResizableTall nmaster delta tiled_ratio []

     -- grid
     grid_ratio = 16/9
     grid = mySpacing $ Grid grid_ratio

     -- monocle
     -- monocle = smartBorders (Full)
     monocle = noBorders (Full)

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.

myManageHook = composeAll
    [ className =? "MPlayer"            --> doFloat
    , className =? "Gimp"               --> doFloat
    , resource  =? "desktop_window"     --> doIgnore
    , resource  =? "kdesktop"           --> doIgnore
    , title     =? "Picture in picture" --> doFloat
    , title     =? "Origin"             --> doFloat
    ]

Automatically place floating windows using myPlacement.

Smart placement with a preference for putting windows near the center of the screen, and with 16px gaps at the top and bottom of the screen where no window will be placed.

myPlacement = withGaps (16,0,16,0) (smart (0.5,0.5))

Event Handling

NOTE: 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.

myEventHook = ewmhDesktopsEventHook <+> fullscreenEventHook

Logging

Perform an arbitrary action on each internal state change or X event. See the XMonad.Hooks.DynamicLog extension for examples.

myLogHook = return ()

Startup

Hook

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.

myStartupHook = return()

Main

Now run xmonad with all the defaults we set up.

Run xmonad with the settings you specify. No need to modify this.

main = do
  -- launches polybar
  spawn "/home/sravan/.xmonad/polybar/launch.sh &"

  -- launches xmonad
  xmonad $ docks $ ewmh desktopConfig
    { manageHook         = manageDocks <+> myManageHook <+> placeHook myPlacement <+> manageHook desktopConfig
    , startupHook        = myStartupHook
    , layoutHook         = myLayout
    , borderWidth        = myBorderWidth
    , terminal           = myTerminal
    , modMask            = myModMask
    , normalBorderColor  = myNormalBorderColor
    , focusedBorderColor = myFocusedBorderColor
    , handleEventHook    = myEventHook
    , focusFollowsMouse  = myFocusFollowsMouse
    , clickJustFocuses   = myClickJustFocuses
    , workspaces         = myWorkspaces
    , mouseBindings      = myMouseBindings
    -- , logHook            = myLogHook
    -- , keys               = myKeys
    }
