* Add debugging messages to diagnose issue #931. * Echo the CWD and NERDTree root too. * Ensure DirArrows are trimmed to a single character. Actually, it's up to the user to make sure it's a single character after leading and trailing spaces are removed. Spaces need to be removed so that an accurate level of indentation can be calculated. * Remove debugging statements * Simplify the algorithm for calculating indentation level. 1. Replace the DirArrows with a single space. 2. Count the leading spaces. 3. Divide by 2. This allows users to specify multi-character arrows, where a spaces prevent characters printing on top of each other. |

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/ or :Helptags, 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 | exe 'cd '.argv()[0] | 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.
Note: Executing vim ~/some-directory will open NERDTree and a new edit window. exe 'cd '.argv()[0] sets the pwd of the new edit window to ~/some-directory
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 = '▾'
