State Your Question

I want to close the tab when nerdtree is the only remaining window in the current tab after I close the file in another window.

I'm using the following: autocmd BufEnter * if tabpagenr('$') > 1 && !len(filter(tabpagebuflist(), 'getbufvar(v:val,"&ft") != "nerdtree"')) | tabclose | endif

Can someone please help? This isn't working and I get an error when nerdtree is the only window in a tab.
