Close vim NERDtree on close of file

Question

I am trying out Vim, installed some plugins, amongst which NERDTree, followed some guides and set up a .vimrc (half of whose content I don't understand — yet).

What annoys me, is that if I :wq, vim remains active, it only closes the documents' split-screen. I end up with a fullscreen NERDTree. I would like NERDTree to close too, on closing the last tab or buffers.

Or am I using it wrong?

Answer 1

Put this in your vimrc:

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

Note: \ is to allow multiple line commands

Answer 2

The :wqa command will write all changed buffers and exit Vim. This will close down NerdTree, too.

Answer 3

Actually, using :q just close current split so for closing all splits go back to the terminal we should use :qa, this command closes all splits even NERDTree.

There is a shortcut for :wq and it is :x, the :x write the changes and close the current split, if you wanna save all changes and close all splits and go back to the terminal you can use below command too:

:xa

That is equivalent to:

:wqa
