1. Intro *NERDTree*
What is this "NERD tree"??
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
* A textual filesystem menu is provided which allows you to
create/delete/move file and directory nodes as well as copy (for
supported OSs)
* 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 (netw), so if
you :edit a directory a (slighly modified) NERD tree will appear in the
current window
==============================================================================
2. Functionality provided *NERDTreeFunctionality*
------------------------------------------------------------------------------
2.1. Global Commands *NERDTreeGlobalCommands*
:NERDTree [<start-directory> | <bookmark>] *:NERDTree*
Opens a fresh NERD tree. The root of the tree depends on the argument
given. There are 3 cases: If no argument is given, the current directory
will be used. If a directory is given, that will be used. If a bookmark
name is given, the corresponding directory will be used. For example: >
:NERDTree /home/marty/vim7/src
:NERDTree foo (foo is the name of a bookmark)
<
:NERDTreeFromBookmark <bookmark> *:NERDTreeFromBookmark*
Opens a fresh NERD tree with the root initialized to the dir for
<bookmark>. This only reason to use this command over :NERDTree is for
the completion (which is for bookmarks rather than directories).
:NERDTreeToggle [<start-directory> | <bookmark>] *:NERDTreeToggle*
If a NERD tree already exists for this tab, it is reopened and rendered
again. If no NERD tree exists for this tab then this command acts the
same as the |:NERDTree| command.
:NERDTreeMirror *:NERDTreeMirror*
Shares an existing NERD tree, from another tab, in the current tab.
Changes made to one tree are reflected in both as they are actually the
same buffer.
If only one other NERD tree exists, that tree is automatically mirrored. If
more than one exists, the script will ask which tree to mirror.
:NERDTreeClose *:NERDTreeClose*
Close the NERD tree in this tab.
------------------------------------------------------------------------------
2.2. Bookmarks *NERDTreeBookmarks*
Bookmarks in the NERD tree are a way to tag files or directories of interest.
For example, you could use bookmarks to tag all of your project directories.
------------------------------------------------------------------------------
2.2.1. The Bookmark Table *NERDTreeBookmarkTable*
If the bookmark table is active (see |NERDTree-B| and
|'NERDTreeShowBookmarks'|), it will be rendered above the tree. You can double
click bookmarks or use the |NERDTree-o| mapping to activate them. See also,
|NERDTree-t| and |NERDTree-T|
------------------------------------------------------------------------------
2.2.2. Bookmark commands *NERDTreeBookmarkCommands*
Note that the following commands are only available in the NERD tree buffer.
:Bookmark <name>
Bookmark the current node as <name>. If there is already a <name>
bookmark, it is overwritten. <name> must not contain spaces.
:BookmarkToRoot <bookmark>
Make the directory corresponding to <bookmark> the new root. If a treenode
corresponding to <bookmark> is already cached somewhere in the tree then
the current tree will be used, otherwise a fresh tree will be opened.
Note that if <bookmark> points to a file then its parent will be used
instead.
:RevealBookmark <bookmark>
If the node is cached under the current root then it will be revealed
(i.e. directory nodes above it will be opened) and the cursor will be
placed on it.
:OpenBookmark <bookmark>
<bookmark> must point to a file. The file is opened as though |NERDTree-o|
was applied. If the node is cached under the current root then it will be
revealed and the cursor will be placed on it.
:ClearBookmarks [<bookmarks>]
Remove all the given bookmarks. If no bookmarks are given then remove all
bookmarks on the current node.
:ClearAllBookmarks
Remove all bookmarks.
:ReadBookmarks
Re-read the bookmarks in the |'NERDTreeBookmarksFile'|.
See also |:NERDTree| and |:NERDTreeFromBookmark|.
------------------------------------------------------------------------------
2.2.3. Invalid Bookmarks *NERDTreeInvalidBookmarks*
If invalid bookmarks are detected, the script will issue an error message and
the invalid bookmarks will become unavailable for use.
These bookmarks will still be stored in the bookmarks file (see
|'NERDTreeBookmarksFile'|), down the bottom. There will always be a blank line
after the valid bookmarks but before the invalid ones.
Each line in the bookmarks file represents one bookmark. The proper format is:
<bookmark name><space><full path to the bookmark location>
After you have corrected any invalid bookmarks, either restart vim, or go
:ReadBookmarks from the NERD tree window.

------------------------------------------------------------------------------
*NERDTree-o*
Default key: o
Map option: NERDTreeMapActivateNode
Applies to: files and directories.
If a file node is selected, it is opened in the previous window.
If a directory is selected it is opened or closed depending on its current
state.
If a bookmark that links to a directory is selected then that directory
becomes the new root.
If a bookmark that links to a file is selected then that file is opened in the
previous window.
------------------------------------------------------------------------------
*NERDTree-go*
Default key: go
Map option: None
Applies to: files.
If a file node is selected, it is opened in the previous window, but the

|NERDTree-o|).
------------------------------------------------------------------------------
*NERDTree-t*
Default key: t
Map option: NERDTreeMapOpenInTab
Applies to: files and directories.
Opens the selected file in a new tab. If a directory is selected, a fresh
NERD Tree for that directory is opened in a new tab.
If a bookmark which points to a directory is selected, open a NERD tree for
that directory in a new tab. If the bookmark points to a file, open that file
in a new tab.
------------------------------------------------------------------------------
*NERDTree-T*
Default key: T

2.3. The filesystem menu *NERDTreeFilesysMenu*
The purpose of the filesystem menu is to allow you to perform basic filesystem
operations quickly from the NERD tree rather than the console.
The filesystem menu can be accessed with 'm' mapping and has four supported
operations: >
1. Adding nodes.
2. Move nodes.
3. Deleting nodes.
3. Copying nodes.
<
1. Adding nodes:
To add a node move the cursor onto (or anywhere inside) the directory you wish
to create the new node inside. Select the 'add node' option from the
filesystem menu and type a filename. If the filename you type ends with a '/'
character then a directory will be created. Once the operation is completed,
the cursor is placed on the new node.
2. Move nodes:
To move/rename a node, put the cursor on it and select the 'move' option from
the filesystem menu. Enter the new location for the node and it will be
moved. If the old file is open in a buffer, you will be asked if you wish to
delete that buffer. Once the operation is complete the cursor will be placed
on the renamed node.
3. Deleting nodes:
To delete a node put the cursor on it and select the 'delete' option from the
filesystem menu. After confirmation the node will be deleted. If a file is
deleted but still exists as a buffer you will be given the option to delete
that buffer.
4. Copying nodes:
To copy a node put the cursor on it and select the 'copy' option from the
filesystem menu. Enter the new location and you're done. Note: copying is
currently only supported for *nix operating systems. If someone knows a
one line copying command for windows that doesnt require user confirmation
then id be grateful if you'd email me.
==============================================================================
3. Customisation *NERDTreeOptions*
------------------------------------------------------------------------------
3.1. Customisation summary *NERDTreeOptionSummary*
The script provides the following options that can customise the behaviour the
NERD tree. These options should be set in your vimrc.
|'loaded_nerd_tree'| Turns off the script.
|'NERDChristmasTree'| Tells the NERD tree to make itself colourful
and pretty.
|'NERDTreeAutoCenter'| Controls whether the NERD tree window centers
when the cursor moves within a specified
distance to the top/bottom of the window.
|'NERDTreeAutoCenterThreshold'| Controls the sensitivity of autocentering.
|'NERDTreeCaseSensitiveSort'| Tells the NERD tree whether to be case
sensitive or not when sorting nodes.
|'NERDTreeChDirMode'| Tells the NERD tree if/when it should change
vim's current working directory.
|'NERDTreeHighlightCursorline'| Tell the NERD tree whether to highlight the
current cursor line.
|'NERDTreeHijackNetrw'| Tell the NERD tree whether to replace the netrw
autocommands for exploring local directories.
|'NERDTreeIgnore'| Tells the NERD tree which files to ignore.
|'NERDTreeBookmarksFile'| Where the bookmarks are stored.
|'NERDTreeMouseMode'| Tells the NERD tree how to handle mouse
clicks.
|'NERDTreeQuitOnOpen'| Closes the tree window after opening a file.
|'NERDTreeShowBookmarks'| Tells the NERD tree whether to display the
bookmarks table on startup.
|'NERDTreeShowFiles'| Tells the NERD tree whether to display files
in the tree on startup.
|'NERDTreeShowHidden'| Tells the NERD tree whether to display hidden
files on startup.
|'NERDTreeShowLineNumbers'| Tells the NERD tree whether to display line
numbers in the tree window.
|'NERDTreeSortOrder'| Tell the NERD tree how to sort the nodes in
the tree.
|'NERDTreeWinPos'| Tells the script where to put the NERD tree
window.
|'NERDTreeWinSize'| Sets the window size when the NERD tree is
opened.
------------------------------------------------------------------------------
3.2. Customisation details *NERDTreeOptionDetails*
To enable any of the below options you should put the given line in your
~/.vimrc
*'loaded_nerd_tree'*
If this plugin is making you feel homicidal, it may be a good idea to turn it
off with this line in your vimrc: >
let loaded_nerd_tree=1
<
------------------------------------------------------------------------------
*'NERDChristmasTree'*
Values: 0 or 1.
Default: 1.
If this option is set to 1 then some extra syntax highlighting elements are
added to the nerd tree to make it more colourful.
Set it to 0 for a more vanilla looking tree.
------------------------------------------------------------------------------
*'NERDTreeAutoCenter'*
Values: 0 or 1.
Default: 1
If set to 1, the NERD tree window will center around the cursor if it moves to
within |'NERDTreeAutoCenterThreshold'| lines of the top/bottom of the window.
This is ONLY done in response to tree navigation mappings,
i.e. |NERDTree-J| |NERDTree-K| |NERDTree-C-J| |NERDTree-c-K| |NERDTree-p|
|NERDTree-P|
The centering is done with a |zz| operation.
------------------------------------------------------------------------------
*'NERDTreeAutoCenterThreshold'*
Values: Any natural number.
Default: 3
This option controls the "sensitivity" of the NERD tree auto centering. See
|'NERDTreeAutoCenter'| for details.
------------------------------------------------------------------------------
*'NERDTreeCaseSensitiveSort'*
Values: 0 or 1.
Default: 0.
By default the NERD tree does not sort nodes case sensitively, i.e. nodes
could appear like this: >
bar.c
Baz.c
blarg.c
boner.c
Foo.c
<
But, if you set this option to 1 then the case of the nodes will be taken into
account. The above nodes would then be sorted like this: >
Baz.c
Foo.c
bar.c
blarg.c
boner.c
<
------------------------------------------------------------------------------
*'NERDTreeChDirMode'*
Values: 0, 1 or 2.
Default: 0.
Use this option to tell the script when (if at all) to change the current
working directory (CWD) for vim.
If it is set to 0 then the CWD is never changed by the NERD tree.
If set to 1 then the CWD is changed when the NERD tree is first loaded to the
directory it is initialized in. For example, if you start the NERD tree with >
:NERDTree /home/marty/foobar
<
then the CWD will be changed to /home/marty/foobar and will not be changed
again unless you init another NERD tree with a similar command.
If the option is set to 2 then it behaves the same as if set to 1 except that
the CWD is changed whenever the tree root is changed. For example, if the CWD
is /home/marty/foobar and you make the node for /home/marty/foobar/baz the new
root then the CWD will become /home/marty/foobar/baz.
------------------------------------------------------------------------------
*'NERDTreeHighlightCursorline'*
Values: 0 or 1.
Default: 1.
If set to 1, the current cursor line in the NERD tree buffer will be
highlighted. This is done using the |cursorline| option.
------------------------------------------------------------------------------
*'NERDTreeHijackNetrw'*
Values: 0 or 1.
Default: 1.
If set to 1, doing a >
:edit <some directory>
<
will open up a "secondary" NERD tree instead of a netrw in the target window.
Secondary NERD trees behaves slighly different from a regular trees in the
following respects:
1. 'o' will open the selected file in the same window as the tree,
replacing it.
2. you can have as many secondary tree as you want in the same tab.
------------------------------------------------------------------------------
*'NERDTreeIgnore'*
Values: a list of regular expressions.
Default: ['\~$'].
This option is used to specify which files the NERD tree should ignore. It
must be a list of regular expressions. When the NERD tree is rendered, any
files/dirs that match any of the regex's in 'NERDTreeIgnore' wont be
displayed.
For example if you put the following line in your vimrc: >
let NERDTreeIgnore=['\.vim$', '\~$']
<
then all files ending in .vim or ~ will be ignored.
Note: to tell the NERD tree not to ignore any files you must use the following
line: >
let NERDTreeIgnore=[]
<
The file filters can be turned on and off dynamically with the |NERDTree-f|
mapping.
------------------------------------------------------------------------------
*'NERDTreeBookmarksFile'*
Values: a path
Default: $HOME/.NERDTreeBookmarks
This is where bookmarks are saved. See |NERDTreeBookmarkCommands|.
------------------------------------------------------------------------------
*'NERDTreeMouseMode'*
Values: 1, 2 or 3.
Default: 1.
If set to 1 then a double click on a node is required to open it.
If set to 2 then a single click will open directory nodes, while a double
click will still be required for file nodes.
If set to 3 then a single click will open any node.
Note: a double click anywhere on a line that a tree node is on will
activate it, but all single-click activations must be done on name of the node
itself. For example, if you have the following node: >
| | |-application.rb
<
then (to single click activate it) you must click somewhere in
'application.rb'.
------------------------------------------------------------------------------
*'NERDTreeQuitOnOpen'*
Values: 0 or 1.
Default: 0
If set to 1, the NERD tree window will close after opening a file with the
|NERDTree-o| or |NERDTree-i| mappings.
------------------------------------------------------------------------------
*'NERDTreeShowBookmarks'*
Values: 0 or 1.
Default: 0.
If this option is set to 1 then the bookmarks table will be displayed.
This option can be toggled dynamically, per tree, with the |NERDTree-B|
mapping.
------------------------------------------------------------------------------
*'NERDTreeShowFiles'*
Values: 0 or 1.
Default: 1.
If this option is set to 1 then files are displayed in the NERD tree. If it is
set to 0 then only directories are displayed.
This option can be toggled dynamically, per tree, with the |NERDTree-F|
mapping and is useful for drastically shrinking the tree when you are
navigating to a different part of the tree.
------------------------------------------------------------------------------
*'NERDTreeShowHidden'*
Values: 0 or 1.
Default: 0.
This option tells vim whether to display hidden files by default. This option
can be dynamically toggled, per tree, with the |NERDTree-I| mapping. Use one
of the follow lines to set this option: >
let NERDTreeShowHidden=0
let NERDTreeShowHidden=1
<
------------------------------------------------------------------------------
*'NERDTreeShowLineNumbers'*
Values: 0 or 1.
Default: 0.
This option tells vim whether to display line numbers for the NERD tree
window. Use one of the follow lines to set this option: >
let NERDTreeShowLineNumbers=0
let NERDTreeShowLineNumbers=1
<
------------------------------------------------------------------------------
*'NERDTreeSortOrder'*
Values: a list of regular expressions.
Default: ['\/$', '*', '\.swp$', '\.bak$', '\~$']
This option is set to a list of regular expressions which are used to
specify the order of nodes under their parent.
For example, if the option is set to: >
['\.vim$', '\.c$', '\.h$', '*', 'foobar']
<
then all .vim files will be placed at the top, followed by all .c files then
all .h files. All files containing the string 'foobar' will be placed at the
end. The star is a special flag: it tells the script that every node that
doesnt match any of the other regexps should be placed here.
If no star is present in 'NERDTreeSortOrder' then one is automatically
appended to the array.
The regex '\/$' should be used to match directory nodes.
After this sorting is done, the files in each group are sorted alphabetically.
Other examples: >
(1) ['*', '\/$']
(2) []
(3) ['\/$', '\.rb$', '\.php$', '*', '\.swp$', '\.bak$', '\~$']
<
1. Directories will appear last, everything else will appear above.
2. Everything will simply appear in alphabetical order.
3. Dirs will appear first, then ruby and php. Swap files, bak files and vim
backup files will appear last with everything else preceding them.
------------------------------------------------------------------------------
*'NERDTreeWinPos'*
Values: "left" or "right"
Default: "left".
This option is used to determine where NERD tree window is placed on the
screen.
This option is makes it possible to use two different explorer type
plugins simultaneously. For example, you could have the taglist plugin on the
left of the window and the NERD tree on the right.
------------------------------------------------------------------------------
*'NERDTreeWinSize'*
Values: a positive integer.
Default: 31.
This option is used to change the size of the NERD tree when it is loaded.

4. Hacking the NERD tree *NERDTreeHacking*
Public functions ~
The script provides 2 public functions for your hacking pleasure. Their
signatures are: >
function! NERDTreeGetCurrentNode()
function! NERDTreeGetCurrentPath()
<
The first returns the node object that the cursor is currently on, while the
second returns the corresponding path object.
This is probably a good time to mention that the script implements prototype
style OO. To see the functions that each class provides you can read look at
the code.
Use the node objects to manipulate the structure of the tree. Use the path
objects to access the files/directories the tree nodes represent.
The NERD tree filetype ~
NERD tree buffers have a filetype of "nerdtree". You can use this to hack the
NERD tree via autocommands (on |FileType|) or via an ftplugin.
For example, putting this code in ~/.vim/ftplugin/nerdtree.vim would override
the o mapping, making it open the selected node in a new gvim instance. >
nnoremap <silent> <buffer> o :call <sid>openInNewVimInstance()<cr>
function! s:openInNewVimInstance()
let p = NERDTreeGetCurrentPath()
if p != {}
silent exec "!gvim " . p.strForOS(1) . "&"
endif
endfunction
<
This way you can add new mappings or :commands or override any existing
mapping.
