Quit when where is no active buffer

[michaelkebe]

It would be great if there is no need to quit the NERD_tree* buffers to quit Vim.
Maybe this can be put into the NERDTree as an option?

I have created a small function to get this feature. Just put this code into your .vimrc:

function! NERDTreeQuit()
  redir => buffersoutput
  silent buffers
  redir END
"                     1BufNo  2Mods.     3File           4LineNo
  let pattern = '^\s*\(\d\+\)\(.....\) "\(.*\)"\s\+line \(\d\+\)$'
  let windowfound = 0

  for bline in split(buffersoutput, "\n")
    let m = matchlist(bline, pattern)

    if (len(m) > 0)
      if (m[2] =~ '..a..')
        let windowfound = 1
      endif
    endif
  endfor

  if (!windowfound)
    quitall
  endif
endfunction
autocmd WinEnter * call NERDTreeQuit()

Greetings

A better version appears to be the one used in the janus repo:

autocmd WinEnter * call s:CloseIfOnlyNerdTreeLeft()

" Close all open buffers on entering a window if the only
" buffer that's left is the NERDTree buffer
function! s:CloseIfOnlyNerdTreeLeft()
  if exists("t:NERDTreeBufName")
    if bufwinnr(t:NERDTreeBufName) != -1
      if winnr("$") == 1
        q
      endif
    endif
  endif
endfunction

It's perfect thanks you :)

Hey guys

This is currently not something that im keen to put in the core plugin, but you can stick something like this in your vimrc to achieve the same thing:

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

excellent

Thanks! Been looking for this for some time, got it from here; http://stackoverflow.com/questions/2066590/automatically-quit-vim-if-nerdtree-is-last-and-only-buffer

[jcottrell]

The solutions above don't seem to account for buffers that are hidden. They close out of vim with hidden buffers still present. Is there something I'm missing?

Thanks! This really helps me.

thanks,it works!

O joy! scrooloose's one liner works!

[justonia]

For anyone coming here from Stack Overflow, the one liner above no longer works. The README now says to use this:

autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif

michaelkebe's is also not working - It also closes vim when I try to switch to the nerdtree window with Ctrl-w p

@justonia thanks !! it is wonderful . I am the guy come from stackoverflow.
By the way , I just want to ask why this old code no work ? cause I upgrade the vim ?
My current vim version is 7.4 ; os is MAC OSX

//old code   no working
autocmd bufenter * if (winnr("$") == 1 && exists('b:NERDTreeType') &&b:NERDTreeType == 'primary') | q | endif

Any how. Thanks you very much!
