This bug is subtle! Opening a directory node in a new tab (with the "t" or "T" mappings) would previously fail and require a refresh because it called the directory node's "activate()" method. In reviewing that method (i.e., "activate()"), I discovered that the directory node's NERDTree is rendered before the method returns, which overwrites the content of the tree in the new tab or window. To clarify, when "t" or "T" is used on a directory node, a new directory node and tree must be created to be rendered in a new tab. So, calling "self.getNerdtree().render()" at the bottom of "activate()" will render the NERDTree instance from which "t" or "T" was invoked, not the new NERDTree that is being displayed. This overwrites the new NERDTree text, and, thus, a refresh is required. Since a call to "render()" is almost always necessary at the bottom of "activate()" to keep everything in sync for other mappings, we avoid this problem entirely by using the "open()" method directly (works for files and directories) in the callbacks. Fixes #549. |

The NERDTree
Introduction
The NERDTree is a file system explorer for the Vim editor. Using this plugin, users can visually browse complex directory hierarchies, quickly open files for reading or editing, and perform basic file system operations.
This plugin can also be extended with custom mappings using a special API. The details of this API and of other NERDTree features are described in the included documentation.
Installation
pathogen.vim
git clone https://github.com/scrooloose/nerdtree.git ~/.vim/bundle/nerdtree
Then reload Vim, run :helptags ~/.vim/bundle/nerdtree/doc/, and check out :help NERDTree.txt.
apt-vim
apt-vim install -y https://github.com/scrooloose/nerdtree.git
F.A.Q.
Is there any support for
gitflags?
Yes, install nerdtree-git-plugin.
Can I have the nerdtree on every tab automatically?
Nope. If this is something you want then chances are you aren't using tabs and buffers as they were intended to be used. Read this http://stackoverflow.com/questions/102384/using-vims-tabs-like-buffers
If you are interested in this behaviour then consider vim-nerdtree-tabs
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.
How can I map a specific key or shortcut to open NERDTree?
Stick this in your vimrc to open NERDTree with Ctrl+n (you can set whatever key you want):
map <C-n> :NERDTreeToggle<CR>
How can I close vim if the only window left open is a NERDTree?
Stick this in your vimrc:
autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif
Can I have different highlighting for different file extensions?
See here: https://github.com/scrooloose/nerdtree/issues/433#issuecomment-92590696
How can I change default arrows?
Use these variables in your vimrc. Note that below are default arrow symbols
let g:NERDTreeDirArrowExpandable = '▸'
let g:NERDTreeDirArrowCollapsible = '▾'
