Xmonad：如何重置主窗格中的窗口数量？

Question

有时，当我在 Xmonad 中 mod-L 或 mod-H 时，我的窗口不会调整大小。我相信这是我不小心更改了主窗格中窗口数量的结果。有时我很幸运能够点击适量的 mod-, 或 mod-. 回到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 在启动时为其提供的默认值？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"

我对这个文件的编辑太少了，以至于我几乎忘记了从手册页和 haddock 编译中费力挑选所收集到的有关 Xmonad API 的所有内容。是否有 Xmonad API 的优秀文档资源，但不是严格的参考工作？

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

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-." ]

我不知道还有比文档中提供的更好的文档源xmonad.org 上的选项卡。
