How to open a file in new tab by default in NERDTree?

Question

I want a file to be opened in a new tab when I enter or double click it. I know there is t shortcut but I always open a file in a new tab and enter is more confortable for me.

s will open the file currently under the cursor in a new vertically split window. Use t to open in a new tab.

Nice. This closes NERDTree window. Is there anyway to keep it open. – Bakul G May 13 '20 at 20:47

Found that 'T' opens in new tab – Bakul G May 13 '20 at 20:48

Try adding

let NERDTreeMapOpenInTab='\r'

or

let NERDTreeMapOpenInTab='<ENTER>'

to your .vimrc.

This also causes enter on a directory to open in a new tab. – alice Dec 31 '11 at 09:17

It doesn't work with gvim x32 with my windows 7 x64. Any idea? – fx-kirin May 14 '15 at 02:30
There is this NerdTree + tabs plugin: https://github.com/jistr/vim-nerdtree-tabs could be useful. – anh_ng8 Oct 11 '16 at 12:02
While this technically answers the question, it renders directories inaccessible. – oarfish Oct 29 '17 at 20:50

@alice @oarfish try this: `let NERDTreeMapActivateNode='v'` - you can use the `v` key to open/close directory nodes. – bvpx Dec 13 '17 at 19:54

As described in section NERDTreeCustomOpenArgs of the NerdTree help, you can use this option to control the opening behavior of files and directories. Add the following statement to your .vimrc:

let NERDTreeCustomOpenArgs={'file':{'where': 't'}}

This ensures in this case that only files in a new tab are opened. All other combinations can be found in the help.

You may want to add https://github.com/Nopik/vim-nerdtree-direnter plugin as well - it fixes the directory opening problem, so enter on directory node will just expand/collapse, not open new tab.

I use following map to do tab traverse :

nnoremap <C-l> gt
nnoremap <C-h> gT

Also, would this not conflict the default mapping of moving between split panes? Because I have tried doing exactly this. – Aman Oct 05 '20 at 13:07

Add this to the plugin. It needs to be added to a file such as: ~/.vim/nerdtree_plugin/mymapping.vim. The exact location will depend on what plugin manager you use for vim. e.g. for Plugged it is ~/.vim/plugged/nerdtree/nerdtree_plugin/mymapping.vim

This code adds a mapping for the enter key to open files in a new tab while just expanding/collapsing directories. For the new tabs it also mirrors the NERDTree so it can be shared between tabs.

call NERDTreeAddKeyMap({
  \ 'key': '<CR>',
  \ 'scope': "Node",
  \ 'callback': 'OpenInNewTab',
  \ 'quickhelpText': 'open node' })


" FUNCTION: s:openInNewTab(target) {{{1
function! OpenInNewTab(node)
  if a:node.path.isDirectory
    call a:node.activate()
  else
    call a:node.activate({'where': 't'})
    call g:NERDTreeCreator.CreateMirror()
    wincmd l
  endif
endfunction

Will this be overwritten if I need to update the plugin? I assume it will if I delete then reinstall it. — , Sep 15 '17 at 14:43

For the double-click event specifically, it is (only?) possible by slightly changing the NERDtree source code (posted here):

Please, add the relevant information from your link into your answer. – Fjodr Jul 22 '15 at 18:42
Changing the source code is a very bad idea, especially since NerdTree offers a lot of options for configuration. – chrboesch Jun 16 '20 at 07:31
