如果NERDTree和TagList仅剩2个缓冲区，则自动退出Vim

Question

I have this code taken from another StackOverflow user Conner, from this question Automatically quit Vim if NERDTree and TagList are the last and only buffers

(There wasn't an option for me to comment on that question, so my only option was to ask a new one).

The question is: How do I close Vim editor (in Linux Mint) if only NERDTree and TagList are the only two buffers left?

The answer provided was:

" If only 2 windows left, NERDTree and Tag_List, close vim or current tab
fun! NoExcitingBuffersLeft()
  if winnr("$") == 3
    let w1 = bufname(winbufnr(1))
    let w2 = bufname(winbufnr(2))
    let w3 = bufname(winbufnr(3))
    if (exists(":NERDTree")) && (w1 == "__Tag_List__" || w2 == "__Tag_List__" || w3 == "__Tag_List__")
      if tabpagenr("$") == 1
        exec 'qa'
      else
        exec 'tabclose'
      endif
    endif
  endif
endfun
autocmd BufWinLeave * call NoExcitingBuffersLeft()

But that does not work properly. Is closes whenever I close the last "exciting" buffer (one that is non-NERDTree or non-TagList), but it also closes whenever I try to open a new file from NERDTree (by double clicking on a filename in the "explorer").

Honestly, I do not understand this code too well. I have tried to mess around with it but I couldn't get the results I would like.

How do I alter this code to not close when I open a new file from NERDTree explorer?

Thank you, Conner, and the rest of the community!

From the Taglist manual, put on your .vimrc file

let Tlist_Exit_OnlyWindow=1

I don't use NERDTree, but you may succeed with the following

autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTreeType") && b:NERDTreeType == "primary") | q | endif
