$vim
$Error detected while processing /Users/me/.vimrc:
E518: Unknown option: \ %{SetTimeOfDayColors()}

这是vim脚本(它目前在我的.vimrc中)

function SetTimeOfDayColors()
    let currentHour = strftime("%H")
    echo "currentHour is " . currentHour
    if currentHour < 6 + 0
      let colorScheme = "darkblue"
    elseif currentHour < 12 + 0
      let colorScheme = "morning"
    elseif currentHour < 18 + 0
      let colorScheme = "shine"
    else
      let colorScheme = "evening"
    endif
    echo "setting color scheme to " . colorScheme
    execute "colorscheme " . colorScheme
endfunction
set statusline=%<%f\ %h%m%r%=%-20.(line=%l,col=%c%V,totlin=%L%)\%h%m%r%=%-40(,bytval=0x%B,%n%Y%)\ %{strftime(\"%c\")}%=0x%B\ %P
set statusline += \ %{SetTimeOfDayColors()}

最后一行的目的是每当我进行编辑并运行自定义函数时让vim检查时间.但我无法让它发挥作用.有什么建议？谢谢.
