--
-- Useful imports
--
import XMonad
import Operations
import qualified StackSet as W
import Data.Ratio
import Data.Bits ((.|.))
import qualified Data.Map as M
import System.Exit
import Graphics.X11.Xlib

-- % Extension-provided imports

-- | 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 :: [WorkspaceId]
workspaces = map show [1 .. 9 :: Int]

-- | 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.
--
modMask :: KeyMask
modMask = 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.
--
numlockMask :: KeyMask
numlockMask = mod2Mask

-- | Width of the window border in pixels.
--
borderWidth :: Dimension
borderWidth = 1

-- | Border colors for unfocused and focused windows, respectively.
--
normalBorderColor, focusedBorderColor :: String
normalBorderColor  = "#dddddd"
focusedBorderColor = "#ff0000"

-- | Default offset of drawable screen boundaries from each physical
-- screen. Anything non-zero here will leave a gap of that many pixels
-- on the given edge, on the that screen. A useful gap at top of screen
-- for a menu bar (e.g. 15)
--
-- An example, to set a top gap on monitor 1, and a gap on the bottom of
-- monitor 2, you'd use a list of geometries like so:
--
-- > defaultGaps = [(18,0,0,0),(0,18,0,0)] -- 2 gaps on 2 monitors
--
-- Fields are: top, bottom, left, right.
--
defaultGaps :: [(Int,Int,Int,Int)]
defaultGaps = [(0,0,0,0)] -- 15 for default dzen font

------------------------------------------------------------------------
-- 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.
--
manageHook :: Window -- ^ the new window to manage
           -> String -- ^ window title
           -> String -- ^ window resource name
           -> String -- ^ window resource class
           -> X (WindowSet -> WindowSet)

-- Always float various programs:
manageHook w _ _ c | c `elem` floats = fmap (W.float w . snd) (floatLocation w)
 where floats = ["MPlayer", "Gimp"]

-- Desktop panels and dock apps should be ignored by xmonad:
manageHook w _ n _ | n `elem` ignore = reveal w >> return (W.delete w)
 where ignore = ["gnome-panel", "desktop_window", "kicker", "kdesktop"]

-- Automatically send Firefox windows to the "web" workspace:
-- If a workspace named "web" doesn't exist, the window will appear on the
-- current workspace.
manageHook _ _ "Gecko" _ = return $ W.shift "web"

-- The default rule: return the WindowSet unmodified.  You typically do not
-- want to modify this line.
manageHook _ _ _ _ = return id

------------------------------------------------------------------------
-- Extensible 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 list of possible layouts. Add your custom layouts to this list.
layouts :: [Layout Window]
layouts = [ Layout tiled
          , Layout $ Mirror tiled
          , Layout Full
          -- Add extra layouts you want to use here:
          -- % Extension-provided layouts
          ]
  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

-- | The top level layout switcher. Most users will not need to modify this binding.
--
-- By default, we simply switch between the layouts listed in `layouts'
-- above, but you may program your own selection behaviour here. Layout
-- transformers, for example, would be hooked in here.
--
layoutHook :: Layout Window
layoutHook = Layout $ Select layouts

-- | Register with xmonad a list of layouts whose state we can preserve over restarts.
-- There is typically no need to modify this list, the defaults are fine.
--
serialisedLayouts :: [Layout Window]
serialisedLayouts = layoutHook : layouts

------------------------------------------------------------------------
-- Logging

-- | Perform an arbitrary action on each internal state change or X event.
-- Examples include:
--      * do nothing
--      * log the state to stdout
--
-- See the 'DynamicLog' extension for examples.
