-- % 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
-- | 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)]

-- 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 available layouts. Note that each layout is separated by |||, which
-- denotes layout choice.
layout = tiled ||| Mirror tiled ||| 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
