在类似Fedora的发行版上修改XMonad配置

Question

我正在使用Fedora派生的发行版，其中XMonad与窗口环境很好地配合。我main中的~/.xmonad.xmonad.hs作业类似于

main = do 
     session <- getEnv "DESKTOP_SESSION" 
     xmonad $ maybe desktopConfig desktop session 

desktop "gnome"        = gnomeConfig 
desktop "kde"          = kde4Config 
desktop "xfce"         = xfceConfig 
desktop "xmonad-gnome" = gnomeConfig 
desktop _              = desktopConfig 

我看到所有这些光滑的修改，我可以做一个la

xmonad $ desktopConfig {
   manageHook = myManageHook <+> manageHook desktopConfig
 , layoutHook = simpleTabbed ||| layoutHook desktopConfig
 }

在像http://xmonad.org/xmonad-docs/xmonad-contrib/XMonad-Config-Desktop.html这样的地方。

我是一个完整的Haskell noob。我怎样才能干净地修改          xmonad $ maybe desktopConfig桌面会话 是否允许以不破坏窗口环境调度的方式添加这些好东西？

Answer 1

main = do 
    session <- getEnv "DESKTOP_SESSION" 
    let config = maybe desktopConfig desktop session
    xmonad $ config{ manageHook = myManageHook <+> manageHook config, ... }
