Auto-open NERDTree in "EVERY" tab

Question

Is it possible to open NERDTree in every tab with pressing t or T in NERDTree, if yes, How?

How do you open it in split view? It works, but it opened the file over it when i double clicked on the file. vim newbie here... — ma11hew28, Jun 23 '10 at 16:26

autocmd VimEnter * NERDTree
autocmd BufEnter * NERDTreeMirror

edit: The above command seems to open the new tab in NERDTree's buffer. Instead use this as mentioned by wejrowski in the comment below :

autocmd BufWinEnter * NERDTreeMirror

You add these to your ~/.vimrc – Kris Dec 15 '10 at 10:45

I did this and when I open a file through nerdtree in a new tab "t" it opens the file in a new tab in the side nerdtree panel and makes the main area blank. so there's no nerdtree anymore. – wejrowski Nov 20 '12 at 21:55

Hmm I fixed it by swapping "autocmd BufEnter * NERDTreeMirror" with "autocmd BufWinEnter * NERDTreeMirror".. seems like it was opening nerdTree then using that nerdtree window to open the buffer – wejrowski Nov 20 '12 at 23:30

this is the wrong answer. use nerdtreetabs. nerdtree is garbage without it – Andy Ray Feb 14 '13 at 19:10
Quickfix window doesn't work properly with that. – schmijos Jan 18 '22 at 14:57

I wrote a vim plugin that does this and also adds some goodies on top (i.e. keeps all trees in sync, ensures meaningful tab captions - not captions like 'NERD_tree_1' etc.).

It's here on Github: https://github.com/jistr/vim-nerdtree-tabs

this plugin seems to work really well, fixes all of these types of shortcomings in NERDTree. Good job! – Daniel OCallaghan Dec 14 '11 at 04:00

used for two seconds so far, and i love it – lakemalcom Jan 12 '12 at 22:20
This is the way NERDTree should work out of the box. Thank you. – jeremyjjbrown Apr 25 '14 at 13:55
Thanks so much for writing this dude -- super useful! It still works with the latest version of NERDTree -- hopefully it continues to work. – Luke Davis Nov 27 '17 at 21:43

autocmd VimEnter * NERDTree
autocmd BufEnter * NERDTreeMirror

autocmd VimEnter * wincmd w

This one is a little better than Dustin's one because it places the cursor directly on the file you are intending to edit for quick edits. Thanks dustin for the original example ^^

A better solution is to open NERDTree only if there are no command line arguments set.

" Open NERDTree in new tabs and windows if no command line args set autocmd VimEnter * if !argc() | NERDTree | endif autocmd BufEnter * if !argc() | NERDTreeMirror | endif

NERDTree is e.g. not helpful if you do a git commit or something similiar.

This is probably not the best way, but if you edit plugin/NERDTree.vim and change this:

 exec "nnoremap <silent> <buffer> ". g:NERDTreeMapOpenInTab ." :call <SID>openInNewTab(0)<cr>"

to this:

 exec "nnoremap <silent> <buffer> ". g:NERDTreeMapOpenInTab ." :call <SID>openInNewTab(0)<cr>:NERDTree<cr>"

it will alter the binding of 't' in the NERDTree view to first open the file and then open NERDTree. Note, that the NERDTree views will not keep in sync.

How about toggling it.

" in .vimrc
" NERDTree, Use F3 for toggle NERDTree
nmap <silent> <F3> :NERDTreeToggle<CR>

In OSX, you just need to fn-F3 to toggle NERDTree.

This problem was actually mentioned in the official Repository's Readme file including three situations related to opening NERDTree automatically:

How can I open a NERDTree automatically when vim starts up?

Stick this in your vimrc: autocmd vimenter * NERDTree

How can I open a NERDTree automatically when vim starts up if no files were specified?

Stick this in your vimrc:

autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists("s:std_in") | NERDTree | endif

Note: Now start vim with plain vim, not vim .

How can I open NERDTree automatically when vim starts up on opening a directory?

autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists("s:std_in") | exe 'NERDTree' argv()[0] | wincmd p | ene | endif

This window is tab-specific, meaning it's used by all windows in the tab. This trick also prevents NERDTree from hiding when first selecting a file.
