+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 directory 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 <start-directory> or <bookmark> is given, the root of NERDTree
+    is set to that path. If no NERDTree exists for this tab then this command
+    acts the same as the |:NERDTree| command.
+
+:NERDTreeToggleVCS [<start-directory> | <bookmark>]         *:NERDTreeToggleVCS*
+    Like |:NERDTreeToggle|, 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: >
+        :NERDTreeToggleVCS /home/marty/nerdtree/doc  (opens /home/marty/nerdtree)
+        :NERDTreeToggleVCS              (opens root of repository containing CWD)
+
+: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.
+
+------------------------------------------------------------------------------
+2.3. NERDTree Mappings                                        *NERDTreeMappings*

+Default key: o
+Map setting: 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

+
+------------------------------------------------------------------------------
+                                                                   *NERDTree-go*
+Default key: go
+Map setting: NERDTreeMapPreview
+Applies to: files.
+
+If a file node or a bookmark that links to a file is selected, it is opened in

+
+------------------------------------------------------------------------------
+                                                                    *NERDTree-t*
+Default key: t
+Map setting: *NERDTreeMapOpenInTab*
+Applies to: files and directories.
+
+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.
+
+------------------------------------------------------------------------------
+                                                                    *NERDTree-T*

+ 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 directories. exec_menuitem.vim
+provides a menu item to execute executable files.

+
+|NERDTreeAutoDeleteBuffer|    Tells the NERDTree to automatically remove a

+
+|NERDTreeRemoveFileCmd|       Specify a custom shell command to be used when
+                            deleting files. Note that it should include one

+------------------------------------------------------------------------------
+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
+<
+------------------------------------------------------------------------------
+                                                                *NERDTreeUseTCD*
+Values: 0 or 1.
+Default: 0.
+
+By default, NERDTree will use the `:cd` command to change the current working
+directory. If this setting is turned on, and the `:tcd` command is available, it
+will be used instead.
+
+------------------------------------------------------------------------------
+                                                             *NERDTreeChDirMode*
+Values: 0, 1, 2, or 3.
+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.
+
+If the set to 3, then it behaves the same as if set to 2, and the CWD is
+changed whenever changing tabs to whatever the tree root is on that tab.
+
+------------------------------------------------------------------------------
+                                                   *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: ['\~$'].
+
+This setting is used to specify which files the NERDTree should ignore.  It
+must be a list of regular expressions. When the NERDTree is rendered, any
+files/directories that match any of the regex's in NERDTreeIgnore won't be
+displayed.
+
+For example if you put the following line in your vimrc: >
+    let NERDTreeIgnore=['\.vim$', '\~$']
+<
+then all files ending in .vim or ~ will be ignored.
+
+There are 3 magic flags that can be appended to the end of each regular
+expression to specify that the regex should match only filenames, only lowest
+level directories, or a full path. These flags are "[[dir]]", "[[file]]", and
+"[[path]]". Example: >
+    let NERDTreeIgnore=['\.d$[[dir]]', '\.o$[[file]]', 'tmp/cache$[[path]]']
+<
+This will cause all directories ending in ".d" to be ignored, all files ending
+in ".o" to be ignored, and the "cache" subdirectory of any "tmp" directory to
+be ignored. All other "cache" directories will be displayed.
+
+When using the "[[path]]" tag on Windows, make sure you use escaped
+backslashes for the separators in the regex, eg. 'Temp\\cache$[[path]]'
+
+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.

+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

+Values: 0 or 1.
+Default: 0.
+
+If this setting is set to 1 then the bookmarks table will be displayed.
+
+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.
+
+This setting tells vim whether to display hidden files by default. This
+setting can be dynamically toggled, per tree, with the |NERDTree-I| mapping.
+Use one of the follow lines for this setting: >
+    let NERDTreeShowHidden=0
+    let NERDTreeShowHidden=1
+<
+------------------------------------------------------------------------------
+                                                       *NERDTreeShowLineNumbers*
+Values: 0 or 1.
+Default: 0.
+
+This setting tells vim whether to display line numbers for the NERDTree
+window.  Use one of the follow lines for this setting: >
+    let NERDTreeShowLineNumbers=0
+    let NERDTreeShowLineNumbers=1
+<
+------------------------------------------------------------------------------
+                                                             *NERDTreeSortOrder*
+Values: a list of regular expressions.
+Default: ['\/$', '*', '\.swp$',  '\.bak$', '\~$']
+
+This setting is a list of regular expressions which are used to group or sort
+the nodes under their parent.
+
+For example, if the setting is: >
+    ['\.vim$', '\.c$', '\.h$', '*', 'foobar']
+<
+then all .vim files will be grouped at the top, followed by all .c files then
+all .h files. All files containing the string 'foobar' will be placed at the
+end.  The star is a special flag: it tells the script that every node that
+doesn't match any of the other regexps should be placed here.
+
+If no star is present in NERDTreeSortOrder, then one is automatically
+appended to the end of the list.
+
+The regex '\/$' should be used to match directory nodes.
+
+Files can also be sorted by 1) the modification timestamp, 2) the size, or 3)
+the extension. Directories are always sorted by name. To accomplish this, the
+following special flags are used:
+  [[timestamp]]   [[-timestamp]]   [[size]]   [[-size]]   [[extension]]
+The hyphen specifies a descending sort; extensions are sorted in ascending
+order only. If placed at the beginning of the list, files are sorted according
+to these flags first, and then grouped by the remaining items in the list. If
+the flags are in any other position of the list, this special 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$',  '\.bak$', '\~$']
+    (4) ['[[-size]]']
+    (5) ['\/$', '*', '[[timestamp]]']
+    (6) ['foo','\/$','[[extension]]']
+<
+1. Directories will appear last, everything else will appear above.
+2. Everything will simply appear in alphabetical order.
+3. Directories will appear first, then ruby and php. Swap files, bak files
+   and vim backup files will appear last with everything else preceding them.
+4. Everything is sorted by size, largest to smallest, with directories
+   considered to have size 0 bytes.
+5. Directories will appear first alphabetically, followed by files, sorted by
+   timestamp, oldest first.
+6. Files and directories matching 'foo' first, followed by other directories,
+   then all other files. Each section of files is sorted by file extension.
+
+------------------------------------------------------------------------------
+                                                            *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 directory nodes, this setting tells NERDTree to collapse
+directories 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 directory nodes, this setting tells NERDTree to recursively open
+directories that have only one child which is also a directory. NERDTree will
+stop when it finds a directory that contains anything but another single
+directory. This setting also causes the |NERDTree-x| mapping to close
+directories 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.
+Example: >
+    let NERDTreeDirArrowExpandable=">"
+    let NERDTreeDirArrowCollapsible="v"
+<
+They can be set to "\u00a0" to replace the arrows with a non-breaking space.
+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.
+
+Alternatively, they can be set to '' (an empty string). This removes the
+arrows and the single space that follows them, shifting the entire tree two
+character positions to the left.
+
+------------------------------------------------------------------------------
+                                                         *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/preservim/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"
+    (BEL) character, and it is hidden by setting 'conceallevel' to 2. If you
+    use autocommands, make sure none of them change that setting in the
+    NERD_Tree_* 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
+<
+------------------------------------------------------------------------------
+                                                        *NERDTreeCustomOpenArgs*
+Values: A nested dictionary, as described below
+Default: {'file': {'reuse': 'all', 'where': 'p'}, 'dir': {}}
+
+This dictionary contains two keys, 'file' and 'dir', whose values each are
+another dictionary. The inner dictionary is a set of parameters used by
+|NERDTree-<CR>| to open a file or directory. Setting these parameters allows you
+to customize the way the node is opened. The default value matches what
+|NERDTree-o| does. To change that behavior, use these keys and
+values in the inner dictionaries:
+
+'where':    specifies whether the node should be opened in a new split ("h" or
+            "v"), in a new tab ("t") or, in the last window ("p").
+'reuse':    if file is already shown in a window, jump there; takes values
+            "all", "currenttab", or empty
+'keepopen': boolean (0 or 1); if true, the tree window will not be closed
+'stay':     boolean (0 or 1); if true, remain in tree window after opening
+
+For example:
+To open files and directories (creating a new NERDTree) in a new tab, >
+    {'file':{'where': 't'}, 'dir':{'where':'t'}}
+<
+To open a file always in the current tab, and expand directories in place, >
+    {'file': {'reuse':'currenttab', 'where':'p', 'keepopen':1, 'stay':1}}
+<
+==============================================================================
+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
+
+A number of API functions take a callback argument to call. The callback can
+be either a string with the name of a function to call, or a |Funcref| object
+which will be called directly.
+
+------------------------------------------------------------------------------
+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': 'NERDTreeEchoPathHandler',
+               \ 'quickhelpText': 'echo full path of current node',
+               \ 'scope': 'DirNode' })
+
+        function! NERDTreeEchoPathHandler(dirnode)
+            echo a:dirnode.path.str()
+        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 directory 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

+When any of the 3 concrete menu items are selected the function "SomeFunction"

+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.

+5. About                                                         *NERDTreeAbout*
+
+The author of the NERDTree is a terrible terrible monster called Martyzilla
+who gobbles up small children with milk and sugar for breakfast.
+
+He can be reached at martin.grenfell at gmail dot com. He would love to hear
+from you, so feel free to send him suggestions and/or comments about this
+plugin.  Don't be shy --- the worst he can do is slaughter you and stuff you
+in the fridge for later ;)
+
+Martyzilla recruited two other unwitting accomplices to become his minions in
+his quest to conquer the Vim plugin world. While he may still love to receive
+your emails, the best way to send suggestions, bug reports, and questions is
+to submit an issue at http://github.com/preservim/nerdtree/issues.
+
+The latest stable and development versions are on Github.

+Installation ~
+
+1. Install a Nerd Font compatible font [16] or patch your own [17]. Then set
+   your terminal font (or 'guifont' if you are using GUI version of Vim).
+
+2. Install the Vim plugin with your favorite plugin manager, e.g. vim-plug
+   [18]:
+
+   "vim Plug 'ryanoasis/vim-devicons'"
+
+   Always load the vim-devicons as the very last one.
+
+3. Configure Vim
+
+   'vim set encoding=UTF-8'
+
+   No need to set explicitly under Neovim: always uses UTF-8 as the default
+   encoding.

+configure vim to load nerdtree-git-plugin **_before_** VimDevIcons loads. * if
+you are lazy loading Denite [5] using the Dein plugin manager, you will need to
+source VimDevIcons before Denite loads.

+                   *devicons-why-isnt-it-working-how-come-i-dont-see-any-icons*
+Why isn't it working? How come I don't see any icons? ~
+
+- Are you using the patched font provided in the separate repo (Nerd Fonts
+  [13]) or are you patching your own?
+
+- _NOTE:_ if running vim and no font set it will default to the terminal font
+  that is set
+
+- check what the vim/gvim font is set to, from ex mode:
+
+  'vim :set guifont?'
+
+- check if the plugin is loaded (should give '1'), from ex mode:
+
+  'vim :echo loaded_webdevicons'
+
+- check if the plugin is enabled (should give '1'), from ex mode:
+
+  'vim :echo g:webdevicons_enable'
+
+- check if the plugin is enabled for NERDTree (should give '1'), from ex
+  mode:
+
+  - this should _NOT_ need to be set under normal circumstances
+
+  'vim :echo g:webdevicons_enable_nerdtree'
+
+- check if you are able to see the characters, from ex mode:
+
+  'vim :echo g:WebDevIconsUnicodeDecorateFileNodesDefaultSymbol'
+
+- if all this looks correct you may try this to see if any files show flags
+
+  - last resort, see if you can even set the default symbol and have it
+    display anywhere (NERDTree, vim-airline's statusline, vim-airlines's
+    tabline), from ex mode:
+
+  "vim :let g:WebDevIconsUnicodeDecorateFileNodesDefaultSymbol='x'"
+

+       *devicons-how-did-you-get-color-matching-based-on-file-type-in-nerdtree*
+How did you get color matching based on file type in NERDtree? ~
+
+- You can either use this additional plugin: vim-nerdtree-syntax-highlight
+  [49] created by @tiagofumo [50]
+
+- Or you can use my current settings from:
+  https://github.com/scrooloose/nerdtree/issues/201#issuecomment-9954740
+

+       *devicons-how-did-you-get-color-matching-on-just-glyph-icon-in-nerdtree*
+How did you get color matching on just the glyph/icon in NERDtree? ~
+
+- You can add something like this to your |vimrc|
+
+  ```vim " NERDTress File highlighting only the glyph/icon " test highlight
+  just the glyph (icons) in nerdtree: autocmd filetype nerdtree highlight
+  haskell_icon ctermbg=none ctermfg=Red guifg=#ffa500 autocmd filetype
+  nerdtree highlight html_icon ctermbg=none ctermfg=Red guifg=#ffa500 autocmd
+  filetype nerdtree highlight go_icon ctermbg=none ctermfg=Red guifg=#ffa500
+
+  autocmd filetype nerdtree syn match haskell_icon ##
+  containedin=NERDTreeFile " if you are using another syn highlight for a
+  given line (e.g. " NERDTreeHighlightFile) need to give that name in the
+  'containedin' for this " other highlight to work with it autocmd filetype
+  nerdtree syn match html_icon ## containedin=NERDTreeFile,html autocmd
+  filetype nerdtree syn match go_icon ## containedin=NERDTreeFile ```
+
+-------------------------------------------------------------------------------
+How do I solve issues after re-sourcing my *vimrc*?
+
+- Try adding this to the bottom of your |vimrc|
+
+  'vim if exists("g:loaded_webdevicons") call webdevicons#refresh() endif'
+
+-------------------------------------------------------------------------------
+                              *devicons-why-do-i-have-artifacts-after-of-icons*
+Why do I have artifacts after (or instead) of icons? ~
+
+- Dots after icons in NERDTree (on GVim), try:
+
+'vim autocmd FileType nerdtree setlocal nolist'
+
+source: Issue #110 [51]
+
+- Newly created files in NERDTree are slow to show the glyph (icon)
+- check your current setting of ':updatetime?'
+- try setting 'updatetime' in your |vimrc| to a lower value like '250', for
+  more info see: Issue #153 [52]
+
+-------------------------------------------------------------------------------
+                                        *devicons-square-brackets-around-icons*
+Square brackets around icons ~
+
+- By default if your Vim supports conceal you should not see these, debug
+  steps:
+
+  - Check if the plugin feature is set (should be '1'):
+
+  'vim echo g:webdevicons_conceal_nerdtree_brackets'
+
+  - Check that your vim was compiled with the 'conceal' feature (should be
+    '+conceal'):
+
+  ```shell
+
+-------------------------------------------------------------------------------
+                                                       *devicons-from-terminal*
+    from terminal ~
+
+  vim --version | grep conceal ```
+
+  - Check the 'conceallevel' (should be '3'):
+
+  'vim set conceallevel?'
+
+-------------------------------------------------------------------------------
+                    *devicons-do-i-have-to-use-patched-font-such-as-nerd-fonts*
+Do I have to use a patched font such as Nerd Fonts? ~
+
+VimDevIcons was desired to work with Nerd Fonts [13], however you do _not_ have
+to use a patched font or even Nerd Fonts specified glyphs. You have 2 main
+options:
+
+fontconfig fallback
+
+1. Install the NERD Font symbol fonts:
+
+2. Symbols Nerd Font:style=1000-em [53]
+
+3. Symbols Nerd Font:style=2048-em [54]
+
+4. Install 10-nerd-font-symbols.conf [55] for Fontconfig
+
+5. for additional information see: Issue #124 [56] and [Nerd Fonts
+   'fontconfig']
+
+Use your own glyph codepoints
+
+- specify your own glyphs and/or use your own font (see: Character Mappings
+  [57])

+Rationale: Why does this exist? How did this start? ~
+
+After seeing the awesome theme for Atom (seti-ui) and the awesome plugins work
+done for NERDTree and vim-airline and wanting something like this for Vim I
+decided to create my first plugin.
