所以,几年来我的 vimrc 中有以下块:

" This toggles the hilighting of trailing-whitespace.
fun! ToggleExtraWhitespace()

   if exists('b:ews') && b:ews == 1
     "echom "Disabling trailing-whitespace hilighting in" bufnr('%') "..."
      let b:ews=0
      call HighlightExtraWhitespace()

     "echom "-- Removing ExtraWhitespace augroup"
      au!      ExtraWhitespace
      augroup! ExtraWhitespace

   else
     "echom "Enabling trailing-whitespace hilighting in" bufnr('%') "..."
      let b:ews=1
      call HighlightExtraWhitespace()

     "echom "-- Adding ExtraWhitespace augroup"
      augroup  ExtraWhitespace
         au!
         au BufEnter    * match ExtraWhitespace /\s\+$/
         au InsertEnter * match ExtraWhitespace /\s\+\%#\@<!$/
         au InsertLeave * match ExtraWhiteSpace /\s\+$/
      augroup END

      if mode() == "i" | do ExtraWhitespace InsertEnter | else | do ExtraWhitespace BufEnter | endif

   endif
endfun

" This adds (or removes) the actual hilighting to your ColourScheme. (It's must be re-called every
" time you toggle hilighting, or change your scheme.)
fun! HighlightExtraWhitespace()
   if exists('b:ews') && b:ews == 1
     "echom "-- Adding ExtraWhitespace hilighting"
      highlight ExtraWhitespace ctermbg=red guibg=red
   else
     "echom "-- Removing ExtraWhitespace hilighting"
      highlight clear ExtraWhitespace
   endif
endfun
au ColorScheme * call HighlightExtraWhitespace()

" (Uncomment the following line if you want trailing-whitespace hilighted by default!)
bufdo call ToggleExtraWhitespace() | au BufAdd * call ToggleExtraWhitespace()

但是,我刚刚意识到,这会阻止我在一个命令行命令中打开多个文件(我通常vim 中进行浏览,因此我花了这么长时间才注意到!):nvim -o lib/ocameel.ml bin/cli.ml打开两个cli.ml包含,的缓冲区并且没有lib/ocameel.ml根本不开门!

如果我注释掉最后一行,一切正常;我仍然可以手动调用:call ToggleExtraWhitespace(),而且一切都很好。

不过,我真的很想弄清楚为什么添加该自动命令会破坏 vim-entry。我的 BufAdd 搞砸了什么?D:
