only (andersonfreitas)

4.1.0
features:
- NERDTreeFind to reveal the node for the current buffer in the tree,
see |NERDTreeFind|. This effectively merges the FindInNERDTree plugin (by
Doug McInnes) into the script.
- make NERDTreeQuitOnOpen apply to the t/T keymaps too. Thanks to Stefan
Ritter and Rémi Prévost.
- truncate the root node if wider than the tree window. Thanks to Victor
Gonzalez.

- really fix window state restoring
- fix some win32 path escaping issues. Thanks to Stephan Baumeister, Ricky,
jfilip1024, and Chris Chambers
4.0.0
- add a new programmable menu system (see :help NERDTreeMenu).
- add new APIs to add menus/menu-items to the menu system as well as
custom key mappings to the NERD tree buffer (see :help NERDTreeAPI).
- removed the old API functions
- added a mapping to maximize/restore the size of nerd tree window, thanks
to Guillaume Duranceau for the patch. See :help NERDTree-A for details.
- fix a bug where secondary nerd trees (netrw hijacked trees) and
NERDTreeQuitOnOpen didnt play nicely, thanks to Curtis Harvey.
- fix a bug where the script ignored directories whose name ended in a dot,
thanks to Aggelos Orfanakos for the patch.
- fix a bug when using the x mapping on the tree root, thanks to Bryan
Venteicher for the patch.
- fix a bug where the cursor position/window size of the nerd tree buffer
wasnt being stored on closing the window, thanks to Richard Hart.
- fix a bug where NERDTreeMirror would mirror the wrong tree
3.1.1
- fix a bug where a non-listed no-name buffer was getting created every
time the tree windows was created, thanks to Derek Wyatt and owen1
- make <CR> behave the same as the 'o' mapping
- some helptag fixes in the doc, thanks strull
- fix a bug when using :set nohidden and opening a file where the previous
buf was modified. Thanks iElectric
- other minor fixes
3.1.0
New features:
- add mappings to open files in a vsplit, see :help NERDTree-s and :help
NERDTree-gs
- make the statusline for the nerd tree window default to something
hopefully more useful. See :help 'NERDTreeStatusline'
Bugfixes:
- make the hijack netrw functionality work when vim is started with "vim
<some dir>" (thanks to Alf Mikula for the patch).
- fix a bug where the CWD wasnt being changed for some operations even when
NERDTreeChDirMode==2 (thanks to Lucas S. Buchala)
- add -bar to all the nerd tree :commands so they can chain with other
:commands (thanks to tpope)
- fix bugs when ignorecase was set (thanks to nach)
- fix a bug with the relative path code (thanks to nach)
- fix a bug where doing a :cd would cause :NERDTreeToggle to fail (thanks nach)
3.0.1
Bugfixes:
- fix bugs with :NERDTreeToggle and :NERDTreeMirror when 'hidden
was not set
- fix a bug where :NERDTree <path> would fail if <path> was relative and
didnt start with a ./ or ../ Thanks to James Kanze.
- make the q mapping work with secondary (:e <dir> style) trees,
thanks to jamessan
- fix a bunch of small bugs with secondary trees
More insane refactoring.
3.0.0
- hijack netrw so that doing an :edit <directory> will put a NERD tree in
the window rather than a netrw browser. See :help 'NERDTreeHijackNetrw'
- allow sharing of trees across tabs, see :help :NERDTreeMirror
- remove "top" and "bottom" as valid settings for NERDTreeWinPos
- change the '<tab>' mapping to 'i'
- change the 'H' mapping to 'I'
- lots of refactoring

The NERD Tree
=============
Intro
-----
The NERD tree allows you to explore your filesystem and to open files and
directories. It presents the filesystem to you in the form of a tree which you
manipulate with the keyboard and/or mouse. It also allows you to perform
simple filesystem operations.
The following features and functionality are provided by the NERD tree:
* Files and directories are displayed in a hierarchical tree structure
* Different highlighting is provided for the following types of nodes:
* files
* directories
* sym-links
* windows .lnk files
* read-only files
* executable files
* Many (customisable) mappings are provided to manipulate the tree:
* Mappings to open/close/explore directory nodes
* Mappings to open files in new/existing windows/tabs
* Mappings to change the current root of the tree
* Mappings to navigate around the tree
* ...
* Directories and files can be bookmarked.
* Most NERD tree navigation can also be done with the mouse
* Filtering of tree content (can be toggled at runtime)
* custom file filters to prevent e.g. vim backup files being displayed
* optional displaying of hidden files (. files)
* files can be "turned off" so that only directories are displayed
* The position and size of the NERD tree window can be customised
* The order in which the nodes in the tree are listed can be customised.
* A model of your filesystem is created/maintained as you explore it. This
has several advantages:
* All filesystem information is cached and is only re-read on demand
* If you revisit a part of the tree that you left earlier in your
session, the directory nodes will be opened/closed as you left them
* The script remembers the cursor position and window position in the NERD
tree so you can toggle it off (or just close the tree window) and then
reopen it (with NERDTreeToggle) the NERD tree window will appear exactly
as you left it
* You can have a separate NERD tree for each tab, share trees across tabs,
or a mix of both.
* By default the script overrides the default file browser (netrw), so if
you :edit a directory a (slightly modified) NERD tree will appear in the
current window
* A programmable menu system is provided (simulates right clicking on a node)
* one default menu plugin is provided to perform basic filesystem
operations (create/delete/move/copy files/directories)
* There's an API for adding your own keymappings
Installation
------------
#### [pathogen.vim](https://github.com/tpope/vim-pathogen)
git clone https://github.com/scrooloose/nerdtree.git ~/.vim/bundle/nerdtree
Then reload vim, run `:helptags ~/.vim/bundle/nerdtree/doc/`, and check out `:help NERD_tree.txt`.
#### [apt-vim](https://github.com/egalpin/apt-vim)
apt-vim install -y https://github.com/scrooloose/nerdtree.git
Faq
---
> Is there any support for `git` flags?
Yes, install [nerdtree-git-plugin](https://github.com/Xuyuanp/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](https://github.com/jistr/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 = '▾'
