Vim: How to synchronize NERDTree with current opened tab file path?
I'm not sure if there's a NERDTree-specific way to do that, but you can always configure Vim so that it sets the working directory to the current file's directory:
autocmd BufEnter * lcd %:p:h
Now all what you have to do after opening a file in a new tab is :NERDTreeToggle in the new tab itself.
I use the following mapping to view the current buffer in NERDTree:
map <leader>r :NERDTreeFind<cr>
throw a % sign on the end like a boss
:NERDTree %
i have this in my .vimrc, it maps Ctrl+o to toggle nerdtree in the dir of the current buffer:
map <C-o> :NERDTreeToggle %<CR>
