--
-- xmonad example config file.
--
-- A template showing all available configuration hooks,
-- and how to override the defaults in your own xmonad.hs conf file.
--
-- Normally, you'd only override those defaults you care about.
--

-- The preferred terminal program, which is used in a binding below and by
-- certain contrib modules.
--
myTerminal      = "xterm"
 
-- Whether focus follows the mouse pointer.
myFocusFollowsMouse :: Bool
myFocusFollowsMouse = True
 
-- Width of the window border in pixels.
--
myBorderWidth   = 1
 
-- 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       = mod1Mask
 
-- The mask for the numlock key. Numlock status is "masked" from the
-- current modifier status, so the keybindings will work with numlock on or
-- off. You may need to change this on some systems.
--
-- You can find the numlock modifier by running "xmodmap" and looking for a
-- modifier with Num_Lock bound to it:
--
-- > $ xmodmap | grep Num
-- > mod2        Num_Lock (0x4d)
--
-- Set numlockMask = 0 if you don't have a numlock key, or want to treat
-- numlock status separately.
--
myNumlockMask   = mod2Mask
 
-- 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]
--
myWorkspaces    = ["1","2","3","4","5","6","7","8","9"]
 
-- Border colors for unfocused and focused windows, respectively.
--
myNormalBorderColor  = "#dddddd"
myFocusedBorderColor = "#ff0000"
