NerdTree - Reveal file in tree - vim

Question

Is there a shortcut which reveal the current file in the NerdTree directory panel.
Like TextMate 'Reveal file in Drawer' - Ctrl+Command+R

Answer 1

in :h NERDTree:
:NERDTreeFind :NERDTreeFind
Find the current file in the tree. If no tree exists for the current tab,
or the file is not under the current root, then initialize a new tree where
the root is the directory of the current file.
I don't think it's bound to anything by default, so you have to do a keybind yourself.
nmap ,n :NERDTreeFind<CR>
is what appears in my .vimrc, along with
nmap ,m :NERDTreeToggle<CR>

Check this out, it automates the sync operation, whenever you change buffer, the nerdtree will automatically refreshed itself (I copied from here with tiny modifications)
" Check if NERDTree is open or active
function! IsNERDTreeOpen()
return exists("t:NERDTreeBufName") && (bufwinnr(t:NERDTreeBufName) != -1)
endfunction
" Call NERDTreeFind iff NERDTree is active, current window contains a modifiable
" file, and we're not in vimdiff
function! SyncTree()
if &modifiable && IsNERDTreeOpen() && strlen(expand('%')) > 0 && !&diff
NERDTreeFind
wincmd p
endif
endfunction
" Highlight currently open buffer in NERDTree
autocmd BufEnter * call SyncTree()

Answer 3

This should also probably be just a comment. With the current version toggling NerdTree and using SyncTree causes NERDTree to be invoked twice. This modification seems to fix that problem:
" Check if NERDTree is open or active
function! IsNERDTreeOpen()
return exists("t:NERDTreeBufName") && (bufwinnr(t:NERDTreeBufName) != -1)
endfunction
" Call NERDTreeFind iff NERDTree is active, current window contains a modifiable
" file, and we're not in vimdiff
function! SyncTree()
if &modifiable && IsNERDTreeOpen() && strlen(expand('%')) > 0 && !&diff
NERDTreeFind
wincmd p
endif
endfunction
" Highlight currently open buffer in NERDTree
autocmd BufEnter * call SyncTree()
function! ToggleNerdTree()
set eventignore=BufEnter
NERDTreeToggle
set eventignore=
endfunction
nmap <C-n> :call ToggleNerdTree()<CR>

Answer 4

Chen Rushan's answer + the comment worked perfectly well for me, except when the tree is open. With this setting, the current file in the tree will be revealed when the tree is opened.
" Check if NERDTree is open or active
function! IsNERDTreeOpen()
return exists("t:NERDTreeBufName") && (bufwinnr(t:NERDTreeBufName) != -1)
endfunction
function! CheckIfCurrentBufferIsFile()
return strlen(expand('%')) > 0
endfunction
" Call NERDTreeFind iff NERDTree is active, current window contains a modifiable
" file, and we're not in vimdiff
function! SyncTree()
if &modifiable && IsNERDTreeOpen() && CheckIfCurrentBufferIsFile() && !&diff
NERDTreeFind
wincmd p
endif
endfunction
" Highlight currently open buffer in NERDTree
autocmd BufRead * call SyncTree()
function! ToggleTree()
if CheckIfCurrentBufferIsFile()
if IsNERDTreeOpen()
NERDTreeClose
else
NERDTreeFind
endif
else
NERDTree
endif
endfunction
" open NERDTree with ctrl + n
nmap <C-n> :call ToggleTree()<CR>

Answer 5

To go along with Chen Rushan's post, the
autocmd BufEnter * call SyncTree()
won't let NERDTree close. I couldn't find a solution (other than below) that would highlight the current open buffer in NERDTree while allowing NERDTree to Toggle.
Below is what I scraped together to be able to toggle NERDTree and have files highlighted while using Ctrl + ] for my next buffer mapping.
Hopefully others can improve this.
"Buffers
set hidden
function! IsNERDTreeOpen()
return exists("t:NERDTreeBufName") && (bufwinnr(t:NERDTreeBufName) != -1)
endfunction
function! NextBuffer()
bnext
if IsNERDTreeOpen()
NERDTreeFind
wincmd p
endif
endfunction
nnoremap <c-]> <Esc>:call NextBuffer()<CR>
function! PrevBuffer()
bprev
if IsNERDTreeOpen()
NERDTreeFind
wincmd p
endif
endfunction
nnoremap <c-[> <Esc>:call PrevBuffer()<CR>
function! ToggleNT()
NERDTreeToggle
endfunction
map <c-u> <Esc>:call ToggleNT()<cr>

Answer 6

function! NerdTreeToggleFind()
if exists("g:NERDTree") && g:NERDTree.IsOpen()
NERDTreeClose
elseif filereadable(expand('%'))
NERDTreeFind
else
NERDTree
endif
endfunction
nnoremap <C-n> :call NerdTreeToggleFind()<CR>
