Xmonad：如何重置主窗格中的窗口数？

Question

有时候，当我在Xmonad中使用mod-L或mod-H ，我的窗口无法调整大小。 我相信这是由于我不小心更改了主窗格中的窗口数而导致的。 有时我很幸运地碰到了适量的mod-,或mod-. 回到我可以调整大小的位置，但并不经常。

如何将窗格重置为其默认值，即Xmonad在启动时提供的默认值？ 我的xmonad.hs：

import XMonad

import qualified Data.Map as M
import System.Exit
import Graphics.X11.Xlib
import IO (Handle, hPutStrLn)

main = do
  h <- spawnPipe "/usr/bin/xmobar"
  xmonad defaultConfig
             { workspaces = workspaces'
             , borderWidth = borderWidth'
             , logHook = logHook' h
             , terminal = terminal'
             , modMask = mod4Mask
             , layoutHook = layoutHook'
             , manageHook = manageHook'
             , startupHook = setWMName "LG3D"
             }

customPP :: PP
customPP = defaultPP { ppCurrent = xmobarColor "#AFAF87" "" . wrap "<" ">"
                     , ppTitle =  shorten 80
                     , ppSep =  "<fc=#AFAF87> | </fc>"
                     , ppHiddenNoWindows = xmobarColor "#AFAF87" ""
                     , ppUrgent = xmobarColor "#FFFFAF" "" . wrap "[" "]"
                     }

logHook' :: Handle ->  X ()
logHook' h = dynamicLogWithPP $ customPP { ppOutput = hPutStrLn h }

manageHook' :: ManageHook
manageHook' = composeAll [
  isFullscreen --> doFullFloat
  ]

layoutHook' = customLayout

borderWidth' :: Dimension
borderWidth' = 1

normalBorderColor', focusedBorderColor' :: String
normalBorderColor'  = "#333333"
focusedBorderColor' = "#AFAF87"

workspaces' :: [WorkspaceId]
workspaces' = ["1", "2", "3", "4", "5", "6"]


customLayout = avoidStruts $ layoutHints $ smartBorders (Full ||| resizableTile ||| Mirror resizableTile)
    where
    resizableTile = ResizableTall nmaster delta ratio []
    nmaster = 1
    ratio = toRational (2/(1+sqrt(5)::Double))
    delta = 3/100

terminal' :: String
terminal' = "urxvt"

我很少编辑该文件，以至于我忘记了Xmonad API的几乎所有内容，这全都源于繁琐的手册页和haddock编译。 Xmonad API是否有很好的文档资源，而不是严格的参考资料？

默认情况下，mod + shift + space会重置您的布局。 如果您不喜欢removeKeysP 。的行为，则可以使用removeKeysP从配置中删除它们：

import XMonad.Util.EZConfig -- add this line near the top, to the other imports

main = do
  h <- spawnPipe "/usr/bin/xmobar" -- no change here
  xmonad $ defaultConfig -- note the extra ($) here
             { workspaces = workspaces'
             -- etc.
             } `removeKeysP`
             [ "M-,", "M-." ]

我不知道有比xmonad.org的“文档”选项卡上提供的文档更好的文档来源。
