1. Intro *NERDTree*
|
|
|
|
What is this "NERDTree"??
|
|
|
|
The NERDTree 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 NERDTree:
|
|
* 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 NERDTree 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 NERDTree 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 NERDTree window will appear exactly
|
|
as you left it
|
|
* You can have a separate NERDTree 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) NERDTree 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
|
|
|

2. Functionality provided *NERDTreeFunctionality*
|
|
|
|
------------------------------------------------------------------------------
|
|
2.1. Global Commands *NERDTreeGlobalCommands*
|
|
|
|
:NERDTree [<start-directory> | <bookmark>] *:NERDTree*
|
|
Opens a fresh NERDTree. 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)
|
|
<
|
|
:NERDTreeVCS [<start-directory> | <bookmark>] *:NERDTreeVCS*
|
|
Like |:NERDTree|, but searches up the directory tree to find the top of
|
|
the version control system repository, and roots the NERDTree there. It
|
|
works with Git, Subversion, Mercurial, Bazaar, and Darcs repositories. A
|
|
couple of examples: >
|
|
:NERDTreeVCS /home/marty/nerdtree/doc (opens /home/marty/nerdtree)
|
|
:NERDTreeVCS (opens root of repository containing CWD)
|
|
<
|
|
:NERDTreeFromBookmark <bookmark> *:NERDTreeFromBookmark*
|
|
Opens a fresh NERDTree with the root initialized to the dir for
|
|
<bookmark>. The 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 NERDTree already exists for this tab, it is reopened and rendered
|
|
again. If no NERDTree exists for this tab then this command acts the
|
|
same as the |:NERDTree| command.
|
|
|
|
:NERDTreeFocus *:NERDTreeFocus*
|
|
Opens (or reopens) the NERDTree if it is not currently visible;
|
|
otherwise, the cursor is moved to the already-open NERDTree.
|
|
|
|
:NERDTreeMirror *:NERDTreeMirror*
|
|
Shares an existing NERDTree, 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 NERDTree exists, that tree is automatically mirrored.
|
|
If more than one exists, the script will ask which tree to mirror.
|
|
|
|
:NERDTreeClose *:NERDTreeClose*
|
|
Close the NERDTree in this tab.
|
|
|
|
:NERDTreeFind [<path>] *:NERDTreeFind*
|
|
Without the optional argument, find and reveal the file for the active
|
|
buffer in the NERDTree window. With the <path> argument, find and
|
|
reveal the specified path.
|
|
|
|
Focus will be shifted to the NERDTree window, and the cursor will be
|
|
placed on the tree node for the determined path. If a NERDTree for the
|
|
current tab does not exist, a new one will be initialized.
|
|
|
|
:NERDTreeCWD *:NERDTreeCWD*
|
|
Change the NERDTree root to the current working directory. If no
|
|
NERDTree exists for this tab, a new one is opened.
|
|
|
|
:NERDTreeRefreshRoot *:NERDTreeRefreshRoot*
|
|
Refreshes the NERDTree root node.
|
|
|
|
------------------------------------------------------------------------------
|
|
2.2. Bookmarks *NERDTreeBookmarks*
|
|
|
|
Bookmarks in the NERDTree 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: The following commands are only available within the NERDTree buffer.
|
|
|
|
:Bookmark [<name>]
|
|
Bookmark the current node as <name>. If there is already a <name>
|
|
bookmark, it is overwritten. <name> must not contain spaces.
|
|
If <name> is not provided, it defaults to the file or directory name.
|
|
For directories, a trailing slash is present.
|
|
|
|
: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 <name>
|
|
The Bookmark named <name> is opened as if |NERDTree-o| was applied to
|
|
its entry in the Bookmark table. If the Bookmark points to a directory,
|
|
it is made the new root of the current NERDTree. If the Bookmark points
|
|
to a file, that file is opened for editing in another window.
|
|
|
|
:ClearBookmarks [<bookmarks>]
|
|
Remove all the given bookmarks. If no bookmarks are given then remove all
|
|
bookmarks on the current node.
|
|
|
|
:ClearAllBookmarks
|
|
Remove all bookmarks.
|
|
|
|
:EditBookmarks
|
|
Opens the bookmarks file for manual editing, e.g. for removing invalid
|
|
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 at 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>
|
|
|
|
You can use the :EditBookmarks command to open the bookmarks file for editing.
|
|
After you have corrected any invalid bookmarks, either restart vim, or run
|
|
:ReadBookmarks from the NERDTree 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 directory is selected, that directory is found
|
|
in the current NERDTree. If the directory couldn't be found, a new NERDTree is
|
|
created.
|
|
|
|
The default key combo for this mapping is "g" + NERDTreeMapActivateNode (see
|
|
|NERDTree-o|).
|
|

|
|
|
|
Opens the selected file in a new tab. If a directory is selected, a fresh
|
|
NERDTree for that directory is opened in a new tab.
|
|
|
|
If a bookmark which points to a directory is selected, open a NERDTree for
|
|
that directory in a new tab. If the bookmark points to a file, open that file
|
|
in a new tab.
|
|
|
|
------------------------------------------------------------------------------

* loop back thru the siblings of the current nodes parent until we find an
|
|
open dir with children
|
|
* go to the first child of that node
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTree-J*

2.3. The NERDTree menu *NERDTreeMenu*
|
|
|
|
The NERDTree has a menu that can be programmed via the an API (see
|
|
|NERDTreeMenuAPI|). The idea is to simulate the "right click" menus that most
|
|
file explorers have.
|
|
|
|
The script comes with two default menu plugins: exec_menuitem.vim and
|
|
fs_menu.vim. fs_menu.vim adds some basic filesystem operations to the menu for
|
|
creating/deleting/moving/copying files and dirs. exec_menuitem.vim provides a
|
|
menu item to execute executable files.

------------------------------------------------------------------------------
|
|
3.2. Customisation details *NERDTreeSettingsDetails*
|
|
|
|
To enable any of the below settings you should put an appropriate >
|
|
let <setting>=<value>
|
|
<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
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeAutoCenter*
|
|
Values: 0 or 1.
|
|
Default: 1
|
|
|
|
If set to 1, the NERDTree 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 setting controls the "sensitivity" of the NERDTree auto centering. See
|
|
|NERDTreeAutoCenter| for details.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeCaseSensitiveSort*
|
|
Values: 0 or 1.
|
|
Default: 0.
|
|
|
|
By default the NERDTree 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 setting 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
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeNaturalSort*
|
|
Values: 0 or 1.
|
|
Default: 0.
|
|
|
|
By default the NERDTree does not sort nodes in natural sort order, i.e. nodes
|
|
could appear like this: >
|
|
z1.txt
|
|
z10.txt
|
|
z100.txt
|
|
z11.txt
|
|
z110.txt
|
|
z2.txt
|
|
z20.txt
|
|
z3.txt
|
|
<
|
|
But if you set this setting to 1 then the natural sort order will be used. The
|
|
above nodes would then be sorted like this: >
|
|
z1.txt
|
|
z2.txt
|
|
z3.txt
|
|
z10.txt
|
|
z11.txt
|
|
z20.txt
|
|
z100.txt
|
|
z110.txt
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeChDirMode*
|
|
|
|
Values: 0, 1 or 2.
|
|
Default: 0.
|
|
|
|
Use this setting 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 NERDTree.
|
|
|
|
If set to 1 then the CWD is changed when the NERDTree is first loaded to the
|
|
directory it is initialized in. For example, if you start the NERDTree 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 NERDTree with a similar command.
|
|
|
|
If the setting 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 NERDTree buffer will be
|
|
highlighted. This is done using the `'cursorline'` Vim option.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeHijackNetrw*
|
|
Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
If set to 1, doing a >
|
|
:edit <some directory>
|
|
<
|
|
will open up a window level NERDTree instead of a netrw in the target window.
|
|
|
|
Window level trees behaves slightly 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 one tree per window - instead of per tab.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeIgnore*
|
|
Values: a list of regular expressions.
|
|
Default: ['\~$'].
|
|
|
|
This setting is used to specify which files the NERDTree should ignore. It
|
|
must be a list of regular expressions. When the NERDTree is rendered, any
|
|
files/dirs that match any of the regex's in NERDTreeIgnore won't be
|
|
displayed.
|
|
|
|
For example if you put the following line in your vimrc: >
|
|
let NERDTreeIgnore=['\.vim$', '\~$']
|
|
<
|
|
then all files ending in .vim or ~ will be ignored.
|
|
|
|
There are 2 magic flags that can be appended to the end of each regular
|
|
expression to specify that the regex should match only files or only dirs.
|
|
These flags are "[[dir]]" and "[[file]]". Example: >
|
|
let NERDTreeIgnore=['\.d$[[dir]]', '\.o$[[file]]']
|
|
<
|
|
This will cause all dirs ending in ".d" to be ignored and all files ending in
|
|
".o" to be ignored.
|
|
|
|
Note: to tell the NERDTree 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.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeRespectWildIgnore*
|
|
Values: 0 or 1.
|
|
Default: 0.
|
|
|
|
If set to 1, the `'wildignore'` setting is respected.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeBookmarksFile*
|
|
Values: a path
|
|
Default: $HOME/.NERDTreeBookmarks
|
|
|
|
This is where bookmarks are saved. See |NERDTreeBookmarkCommands|.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeBookmarksSort*
|
|
Values: 0, 1, or 2
|
|
Default: 1
|
|
|
|
This setting controls the method by which the list of user bookmarks is
|
|
sorted. When sorted, bookmarks will render in alphabetical order by name.
|
|
|
|
If set to 0, the bookmarks list is not sorted.
|
|
If set to 1, the bookmarks list is sorted in a case-insensitive manner.
|
|
If set to 2, the bookmarks list is sorted in a case-sensitive manner.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeMarkBookmarks*
|
|
Values: 0 or 1
|
|
Default: 1
|
|
|
|
If set to 1, Bookmarks will be specially marked whenever the NERDTree is
|
|
rendered. Users of the |NERDTreeMinimalUI| setting may prefer to disable
|
|
this setting for even less visual clutter.
|
|
|
|
------------------------------------------------------------------------------
|
|
*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: 0,1,2 or 3.
|
|
Default: 0
|
|
|
|
This setting governs whether the NERDTree window or the bookmarks table closes
|
|
after opening a file with the |NERDTree-o|, |NERDTree-i|, |NERDTree-t| and
|
|
|NERDTree-T| mappings.
|
|
|
|
Value | NERDTree Window Behavior
|
|
-------+-------------------------------------------------------
|
|
0 | No change
|
|
1 | Closes after opening a file
|
|
2 | Closes the bookmark table after opening a bookmark
|
|
3(1+2) | Same as both 1 and 2
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeShowBookmarks*
|
|
Values: 0 or 1.
|
|
Default: 0.
|
|
|
|

|
|
|
This setting can be toggled dynamically, per tree, with the |NERDTree-B|
|
|
mapping.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeShowFiles*
|

Values: 0 or 1.
|
|
Default: 1.
|
|
|
|
If this setting is set to 1 then files are displayed in the NERDTree. If it
|
|
is set to 0 then only directories are displayed.
|
|
|
|
This setting 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.
|

|
let NERDTreeShowHidden=0
|
|
let NERDTreeShowHidden=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|

*NERDTreeSortOrder*
|
|
Values: a list of regular expressions.
|
|
Default: ['\/$', '*', '\.swp$', '\.bak$', '\~$']
|
|
|
|
This setting is a list of regular expressions which are used to specify the
|
|
order of nodes under their parent.
|
|
|
|
For example, if the setting is: >
|
|
['\.vim$', '\.c$', '\.h$', '*', 'foobar']
|
|
<
|
|
then all .vim files will be placed at the top, followed by all .c files then
|
|
all .h files. All files containing the string 'foobar' will be placed at the
|
|
end. The star is a special flag: it tells the script that every node that
|
|
doesn't match any of the other regexps should be placed here.
|
|
|
|
If no star is present in NERDTreeSortOrder then one is automatically
|
|
appended to the array.
|
|
|
|
The regex '\/$' should be used to match directory nodes.
|
|
|
|
A special flag can be used to sort by the modification timestamps of files and
|
|
directories. It is either '[[timestamp]]' for ascending, or '[[-timestamp]]'
|
|
for descending. If placed at the beginning of the list, files and directories
|
|
are sorted by timestamp, and then by the remaining items in the sort order
|
|
list. If this flag is in any other position of the list, timestamp sorting is
|
|
done secondarily. See examples 4, 5, and 6 below.
|
|
|
|
After this sorting is done, the files in each group are sorted alphabetically.
|
|
|
|
Examples: >
|
|
(1) ['*', '\/$']
|
|
(2) []
|
|
(3) ['\/$', '\.rb$', '\.php$', '*', '\.swp$', '\.bak$', '\~$']
|
|
(4) ['[[timestamp]]']
|
|
(5) ['\/$', '*', '[[-timestamp]]']
|
|
(6) ['\.md$', '\.c$', '[[-timestamp]]', '*']
|
|
<
|
|
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.
|
|
4. All files and directories are sorted by timestamp, oldest first. If any
|
|
files have identical timestamps, they are sorted alphabetically.
|
|
5. Directories are first, newest to oldest, then everything else, newest to
|
|
oldest.
|
|
6. Markdown files first, followed by C source files, then everything else.
|
|
Each group is shown newest to oldest.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeStatusline*
|
|
Values: Any valid `'statusline'` setting.
|
|
Default: %{exists('b:NERDTree')?b:NERDTree.root.path.str():''}
|
|
|
|
Defines the value for the `'statusline'` setting in NERDTree windows.
|
|
|
|
Note: The setting is actually applied using |:let-&|, not |:set|, so
|
|
escaping spaces is not necessary.
|
|
|
|
Setting this to -1 will deactivate it so that your global `'statusline'`
|
|
setting is used.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeWinPos*
|
|
Values: "left" or "right"
|
|
Default: "left".
|
|
|
|
This setting is used to determine where NERDTree window is placed on the
|
|
screen.
|
|
|
|
This setting makes it possible to use two different explorer plugins
|
|
simultaneously. For example, you could have the taglist plugin on the left of
|
|
the window and the NERDTree on the right.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeWinSize*
|
|
Values: a positive integer.
|
|
Default: 31.
|
|
|
|
This setting is used to change the size of the NERDTree when it is loaded.
|
|
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeMinimalUI*
|
|
Values: 0 or 1
|
|
Default: 0
|
|
|
|
This setting disables the 'Bookmarks' label 'Press ? for help' text. Use one
|
|
of the following lines for this setting: >
|
|
let NERDTreeMinimalUI=0
|
|
let NERDTreeMinimalUI=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeMinimalMenu*
|
|
Values: 0 or 1
|
|
Default: 0
|
|
|
|
This setting makes NERDTree use a smaller, more compact menu for adding,
|
|
copying, deleting nodes. This menu fits on a single line so Vim doesn't need to
|
|
scroll down to present it. This setting is recommended for users already
|
|
familiar with the menu items. It will look similar to this:
|
|
|
|
Menu: [ (a)dd ,m,d,r,o,q,c,l] (Use j/k/enter or shortcut):
|
|
|
|
An action can be selected with its shortcut key or with the NERDTreeMenuUp and
|
|
NERDTreeMenuDown keys, then pressing enter.
|
|
|
|
Use one of the following lines for this setting: >
|
|
let NERDTreeMinimalMenu=0
|
|
let NERDTreeMinimalMenu=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeCascadeSingleChildDir*
|
|
Values: 0 or 1
|
|
Default: 1.
|
|
|
|
When displaying dir nodes, this setting tells NERDTree to collapse dirs that
|
|
have only one child. Use one of the following lines for this setting: >
|
|
let NERDTreeCascadeSingleChildDir=0
|
|
let NERDTreeCascadeSingleChildDir=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeCascadeOpenSingleChildDir*
|
|
Values: 0 or 1
|
|
Default: 1.
|
|
|
|
When opening dir nodes, this setting tells NERDTree to recursively open dirs
|
|
that have only one child which is also a dir. NERDTree will stop when it finds
|
|
a dir that contains anything but another single dir. This setting also causes
|
|
the |NERDTree-x| mapping to close dirs in the same manner. This setting may be
|
|
useful for Java projects. Use one of the following lines for this setting: >
|
|
let NERDTreeCascadeOpenSingleChildDir=0
|
|
let NERDTreeCascadeOpenSingleChildDir=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeAutoDeleteBuffer*
|
|
Values: 0 or 1
|
|
Default: 0.
|
|
|
|
When using a context menu to delete or rename a file you may also want to
|
|
delete the buffer which is no more valid. If the setting is not set you will
|
|
see a confirmation if you really want to delete an old buffer. If you always
|
|
press 'y' then it's worth it to set this setting to 1. Use one of the
|
|
following lines for this setting: >
|
|
let NERDTreeAutoDeleteBuffer=0
|
|
let NERDTreeAutoDeleteBuffer=1
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeCreatePrefix*
|
|
Values: Any valid command prefix.
|
|
Default: "silent".
|
|
|
|
Internally, NERDTree uses the |:edit| command to create a buffer in which to
|
|
display its tree view. You can augment this behavior by specifying a prefix
|
|
string such as "keepalt" or similar. For example, to have NERDTree create its
|
|
tree window using `silent keepalt keepjumps edit`: >
|
|
let NERDTreeCreatePrefix='silent keepalt keepjumps'
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeDirArrowCollapsible* *NERDTreeDirArrowExpandable*
|
|
Values: Any single character.
|
|
Defaults: Windows: ~ and + Others: ▾ and ▸
|
|
|
|
These characters indicate whether a directory is collapsible or expandable.
|
|
|
|
They can be set to "\u00a0" to hide the arrows, but if you do this you may
|
|
need to change the node delimiter. See |NERDTreeNodeDelimiter|. You cannot use
|
|
the same character for both the arrows and the delimiter. Example: >
|
|
let NERDTreeDirArrowExpandable=">"
|
|
let NERDTreeDirArrowCollapsible="v"
|
|
<
|
|
------------------------------------------------------------------------------
|
|
*NERDTreeNodeDelimiter*
|
|
Values: Any single character.
|
|
Default: varies (see below)
|
|
|
|
This character is used to separate the file or directory name from the rest of
|
|
the characters in the line of text. It allows filenames to contain special
|
|
characters that are otherwise used in the NERDTree, such as square brackets,
|
|
braces, trailing asterisk, and leading space. For more details, see the
|
|
responsible pull request: https://github.com/scrooloose/nerdtree/pull/868.
|
|
|
|
The default value of this variable depends on the features compiled into your
|
|
vim and the values of |NERDTreeDirArrowCollapsible| and
|
|
|NERDTreeDirArrowExpandable|.
|
|
* If your vim is compiled with the +conceal feature, it is the "\x07" (BELL)
|
|
character, and it is hidden by setting 'conceallevel' to 3. If you use
|
|
autocommands, make sure none of them change that setting in the NERDTree_*
|
|
buffers.
|
|
* If your vim does NOT have the +conceal feature and you're using "\u00a0"
|
|
(non-breaking space) to hide the directory arrows, "\u00b7" (middle dot)
|
|
is used as the default delimiter.
|
|
* If neither condition above applies, NERDTree uses "\u00a0" (non-breaking
|
|
space) as the default delimiter.
|
|
|
|
In the 2nd and 3rd cases, NERDTree will use the Ignore highlight group to
|
|
"hide" the delimiter. It should appear as an empty space.
|
|
|
|
Other plugins can interfere with these defaults, so if you need to change the
|
|
delimiter, be sure to choose a character that won't appear in your filenames
|
|
or any of the flags set by your installed NERDTree plugins. The suggestions
|
|
below are but a few of the many possibilities. Remember to use double quotes
|
|
when specifying by hex or Unicode. >
|
|
let NERDTreeNodeDelimiter="\x07" "bell
|
|
let NERDTreeNodeDelimiter="\u00b7" "middle dot
|
|
let NERDTreeNodeDelimiter="\u00a0" "non-breaking space
|
|
let NERDTreeNodeDelimiter="😀" "smiley face

4. The NERDTree API *NERDTreeAPI*
|
|
|
|
The NERDTree script allows you to add custom key mappings and menu items via
|
|
a set of API calls. Any scripts that use this API should be placed in
|
|
~/.vim/nerdtree_plugin/ (*nix) or ~/vimfiles/nerdtree_plugin (windows).
|
|
|
|
The script exposes some prototype objects that can be used to manipulate the
|
|
tree and/or get information from it: >
|
|
g:NERDTreePath
|
|
g:NERDTreeDirNode
|
|
g:NERDTreeFileNode
|
|
g:NERDTreeBookmark
|
|
<
|
|
See the code/comments in NERD_tree.vim to find how to use these objects. The
|
|
following code conventions are used:
|
|
* class members start with a capital letter
|
|
* instance members start with a lower case letter
|
|
* private members start with an underscore
|
|
|
|
See this blog post for more details:
|
|
http://got-ravings.blogspot.com/2008/09/vim-pr0n-prototype-based-objects.html
|
|
|
|
------------------------------------------------------------------------------
|
|
4.1. Key map API *NERDTreeKeymapAPI*
|
|
|
|
NERDTreeAddKeyMap({options}) *NERDTreeAddKeyMap()*
|
|
Adds a new keymapping for all NERDTree buffers.
|
|
{options} must be a dictionary, and must contain the following keys:
|
|
"key" - the trigger key for the new mapping
|
|
"callback" - the function the new mapping will be bound to
|
|
"quickhelpText" - the text that will appear in the quickhelp (see
|
|
|NERDTree-?|)
|
|
"override" - if 1 then this new mapping will override whatever previous
|
|
mapping was defined for the key/scope combo. Useful for overriding the
|
|
default mappings.
|
|
|
|
Additionally, a "scope" argument may be supplied. This constrains the
|
|
mapping so that it is only activated if the cursor is on a certain object.
|
|
That object is then passed into the handling method. Possible values are:
|
|
|
|
"FileNode" .... a file node
|
|
"DirNode" ..... a directory node
|
|
"Node" ........ a file node OR a directory node
|
|
"Bookmark" .... a bookmark
|
|
"all" ......... global scope; handler receives no arguments (default)
|
|
|
|
Example: >
|
|
call NERDTreeAddKeyMap({
|
|
\ 'key': 'foo',
|
|
\ 'callback': 'NERDTreeCDHandler',
|
|
\ 'quickhelpText': 'echo full path of current node',
|
|
\ 'scope': 'DirNode' })
|
|
|
|
function! NERDTreeCDHandler(dirnode)
|
|
call a:dirnode.changeToDir()
|
|
endfunction
|
|
<
|
|
This code should sit in a file like ~/.vim/nerdtree_plugin/mymapping.vim.
|
|
It adds a (redundant) mapping on 'foo' which changes vim's CWD to that of
|
|
the current dir node. Note this mapping will only fire when the cursor is
|
|
on a directory node.
|
|
|
|
------------------------------------------------------------------------------
|
|
4.2. Menu API *NERDTreeMenuAPI*
|
|
|
|
NERDTreeAddSubmenu({options}) *NERDTreeAddSubmenu()*
|
|
Creates and returns a new submenu.
|
|
|
|
{options} must be a dictionary and must contain the following keys:
|
|
"text" - the text of the submenu that the user will see
|
|
"shortcut" - a shortcut key for the submenu (need not be unique)
|
|
|
|
The following keys are optional:
|
|
"isActiveCallback" - a function that will be called to determine whether
|
|
this submenu item will be displayed or not. The callback function must
|
|
return 0 or 1.
|
|
"parent" - the parent submenu of the new submenu (returned from a previous
|
|
invocation of NERDTreeAddSubmenu()). If this key is left out then the new
|
|
submenu will sit under the top level menu.
|
|
|
|
See below for an example.
|
|
|
|
NERDTreeAddMenuItem({options}) *NERDTreeAddMenuItem()*
|
|
Adds a new menu item to the NERDTree menu (see |NERDTreeMenu|).
|
|
|
|
{options} must be a dictionary and must contain the
|
|
following keys:
|
|
"text" - the text of the menu item which the user will see
|
|
"shortcut" - a shortcut key for the menu item (need not be unique)
|
|
"callback" - the function that will be called when the user activates the
|
|
menu item.
|
|
|
|
The following keys are optional:
|
|
"isActiveCallback" - a function that will be called to determine whether
|
|
this menu item will be displayed or not. The callback function must return
|
|
0 or 1.
|
|
"parent" - if the menu item belongs under a submenu then this key must be
|
|
specified. This value for this key will be the object that
|
|
was returned when the submenu was created with |NERDTreeAddSubmenu()|.
|
|
|
|
See below for an example.
|
|
|
|
NERDTreeAddMenuSeparator([{options}]) *NERDTreeAddMenuSeparator()*
|
|
Adds a menu separator (a row of dashes).
|
|
|
|
{options} is an optional dictionary that may contain the following keys:
|
|
"isActiveCallback" - see description in |NERDTreeAddMenuItem()|.
|
|
|
|
Below is an example of the menu API in action. >
|
|
call NERDTreeAddMenuSeparator()
|
|
|
|
call NERDTreeAddMenuItem({
|
|
\ 'text': 'a (t)op level menu item',
|
|
\ 'shortcut': 't',
|
|
\ 'callback': 'SomeFunction' })
|
|
|
|
let submenu = NERDTreeAddSubmenu({
|
|
\ 'text': 'a (s)ub menu',
|
|
\ 'shortcut': 's' })
|
|
|
|
call NERDTreeAddMenuItem({
|
|
\ 'text': '(n)ested item 1',
|
|
\ 'shortcut': 'n',
|
|
\ 'callback': 'SomeFunction',
|
|
\ 'parent': submenu })
|
|
|
|
call NERDTreeAddMenuItem({
|
|
\ 'text': '(n)ested item 2',
|
|
\ 'shortcut': 'n',
|
|
\ 'callback': 'SomeFunction',
|
|
\ 'parent': submenu })
|
|
<
|
|
This will create the following menu: >
|
|
--------------------
|
|
a (t)op level menu item
|
|
a (s)ub menu
|
|
<
|
|
Where selecting "a (s)ub menu" will lead to a second menu: >
|
|
(n)ested item 1
|
|
(n)ested item 2
|
|
<
|
|
When any of the 3 concrete menu items are selected the function "SomeFunction"
|
|
will be called.
|
|
|
|
------------------------------------------------------------------------------
|
|
4.3 NERDTreeAddPathFilter(callback) *NERDTreeAddPathFilter()*
|
|
|
|
Path filters are essentially a more powerful version of |NERDTreeIgnore|.
|
|
If the simple regex matching in |NERDTreeIgnore| is not enough then use
|
|
|NERDTreeAddPathFilter()| to add a callback function that paths will be
|
|
checked against when the decision to ignore them is made. Example >
|
|
|
|
call NERDTreeAddPathFilter('MyFilter')
|
|
|
|
function! MyFilter(params)
|
|
"params is a dict containing keys: 'nerdtree' and 'path' which are
|
|
"g:NERDTree and g:NERDTreePath objects
|
|
|
|
"return 1 to ignore params['path'] or 0 otherwise
|
|
endfunction
|
|
<
|
|
------------------------------------------------------------------------------
|
|
4.4 Path Listener API *NERDTreePathListenerAPI*
|
|
|
|
Use this API if you want to run a callback for events on Path objects. E.G >
|
|
|
|
call g:NERDTreePathNotifier.AddListener("init", "MyListener")
|
|
|
|
"....
|
|
|
|
function! MyListener(event)
|
|
"This function will be called whenever a Path object is created.
|
|
|
|
"a:event is an object that contains a bunch of relevant info -
|
|
"including the affected path. See lib/nerdtree/event.vim for details.
|
|
endfunction
|
|
<
|
|
Current events supported:
|
|
init ~
|
|
refresh ~
|
|
refreshFlags ~
|
|
|
|
------------------------------------------------------------------------------
|
|
NERDTreeRender() *NERDTreeRender()*
|
|
Re-renders the NERDTree buffer. Useful if you change the state of the
|
|
tree and you want to it to be reflected in the UI.
|
|
