NerdTree - Reveal file in tree
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()
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>
