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 * 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 * A programmable menu system is provided (simulates right clicking on a node) * one default menu plugin is provided to perform basic filesytem 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 [ | ] *: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 *:NERDTreeFromBookmark* Opens a fresh NERD tree with the root initialized to the dir for . This only reason to use this command over :NERDTree is for the completion (which is for bookmarks rather than directories). :NERDTreeToggle [ | ] *: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 Bookmark the current node as . If there is already a bookmark, it is overwritten. must not contain spaces. :BookmarkToRoot Make the directory corresponding to the new root. If a treenode corresponding to is already cached somewhere in the tree then the current tree will be used, otherwise a fresh tree will be opened. Note that if points to a file then its parent will be used instead. :RevealBookmark 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 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 [] 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: After you have corrected any invalid bookmarks, either restart vim, or go :ReadBookmarks from the NERD tree window. ------------------------------------------------------------------------------ 2.3.

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 cursor does not move. The key combo for this mapping is always "g" + NERDTreeMapActivateNode (see |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 Map option: NERDTreeMapOpenInTabSilent Applies to: files and directories. The same as |NERDTree-t| except that the focus is kept in the current tab. ------------------------------------------------------------------------------ *NERDTree-i* Default key: i Map option: NERDTreeMapOpenSplit Applies to: files. Opens the selected file in a new split window and puts the cursor in the new window. ------------------------------------------------------------------------------ *NERDTree-gi* Default key: gi Map option: None Applies to: files. The same as |NERDTree-i| except that the cursor is not moved. The key combo for this mapping is always "g" + NERDTreeMapOpenSplit (see |NERDTree-i|). ------------------------------------------------------------------------------ *NERDTree-s* Default key: s Map option: NERDTreeMapOpenVSplit Applies to: files. Opens the selected file in a new vertically split window and puts the cursor in the new window. ------------------------------------------------------------------------------ *NERDTree-gs* Default key: gs Map option: None Applies to: files. The same as |NERDTree-s| except that the cursor is not moved. The key combo for this mapping is always "g" + NERDTreeMapOpenVSplit (see |NERDTree-s|). ------------------------------------------------------------------------------ *NERDTree-!* Default key: ! Map option: NERDTreeMapExecute Applies to: files. Executes the selected file, prompting for arguments first. ------------------------------------------------------------------------------ *NERDTree-O* Default key: O Map option: NERDTreeMapOpenRecursively Applies to: directories. Recursively opens the selelected directory. All files and directories are cached, but if a directory would not be displayed due to file filters (see |'NERDTreeIgnore'| |NERDTree-f|) or the hidden file filter (see |'NERDTreeShowHidden'|) then its contents are not cached. This is handy, especially if you have .svn directories. ------------------------------------------------------------------------------ *NERDTree-x* Default key: x Map option: NERDTreeMapCloseDir Applies to: files and directories. Closes the parent of the selected node. ------------------------------------------------------------------------------ *NERDTree-X* Default key: X Map option: NERDTreeMapCloseChildren Applies to: directories. Recursively closes all children of the selected directory. Tip: To quickly "reset" the tree, use |NERDTree-P| with this mapping. ------------------------------------------------------------------------------ *NERDTree-e* Default key: e Map option: NERDTreeMapOpenExpl Applies to: files and directories. |:edit|s the selected directory, or the selected file's directory. This could result in a NERD tree or a netrw being opened, depending on |'NERDTreeHijackNetrw'|. ------------------------------------------------------------------------------ *NERDTree-D* Default key: D Map option: NERDTreeMapDeleteBookmark Applies to: lines in the bookmarks table Deletes the currently selected bookmark. ------------------------------------------------------------------------------ *NERDTree-P* Default key: P Map option: NERDTreeMapJumpRoot Applies to: no restrictions.

If the cursor is already on the first node then do the following: * 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* Default key: J Map option: NERDTreeMapJumpLastChild Applies to: files and directories. Jump to the last child of the current nodes parent. If the cursor is already on the last node then do the following: * loop forward thru the siblings of the current nodes parent until we find an open dir with children * go to the last child of that node ------------------------------------------------------------------------------ *NERDTree-C-J* Default key: Map option: NERDTreeMapJumpNextSibling Applies to: files and directories. Jump to the next sibling of the selected node. ------------------------------------------------------------------------------ *NERDTree-C-K* Default key: Map option: NERDTreeMapJumpPrevSibling Applies to: files and directories. Jump to the previous sibling of the selected node. ------------------------------------------------------------------------------ *NERDTree-C* Default key: C Map option: NERDTreeMapChdir Applies to: directories. Make the selected directory node the new tree root. If a file is selected, its parent is used. ------------------------------------------------------------------------------ *NERDTree-u* Default key: u Map option: NERDTreeMapUpdir Applies to: no restrictions. Move the tree root up a dir (like doing a "cd .."). ------------------------------------------------------------------------------ *NERDTree-U* Default key: U Map option: NERDTreeMapUpdirKeepOpen Applies to: no restrictions. Like |NERDTree-u| except that the old tree root is kept open. ------------------------------------------------------------------------------ *NERDTree-r* Default key: r Map option: NERDTreeMapRefresh Applies to: files and directories. If a dir is selected, recursively refresh that dir, i.e. scan the filesystem for changes and represent them in the tree. If a file node is selected then the above is done on it's parent. ------------------------------------------------------------------------------ *NERDTree-R* Default key: R Map option: NERDTreeMapRefreshRoot Applies to: no restrictions. Recursively refresh the tree root. ------------------------------------------------------------------------------ *NERDTree-m* Default key: m Map option: NERDTreeMapMenu Applies to: files and directories. Display the NERD tree menu. See |NERDTreeMenu| for details. ------------------------------------------------------------------------------ *NERDTree-cd* Default key: cd Map option: NERDTreeMapChdir Applies to: files and directories. Change vims current working directory to that of the selected node. ------------------------------------------------------------------------------ *NERDTree-I* Default key: I Map option: NERDTreeMapToggleHidden Applies to: no restrictions. Toggles whether hidden files (i.e. "dot files") are displayed. ------------------------------------------------------------------------------ *NERDTree-f* Default key: f Map option: NERDTreeMapToggleFilters Applies to: no restrictions.

Map option: NERDTreeMapHelp Applies to: no restrictions. Toggles whether the quickhelp is displayed. ------------------------------------------------------------------------------ 2.3. The NERD tree menu *NERDTreeMenu* The NERD tree 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 one default menu plugin that adds some basic filesystem operations to the menu for creating/deleting/moving/copying files and dirs. ============================================================================== 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. |'NERDTreeStatusline'| Set a statusline for NERD tree windows. |'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 < 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. ------------------------------------------------------------------------------ *'NERDTreeStatusline'* Values: Any valid statusline setting. Default: %{b:NERDTreeRoot.path.strForOS(0)} Tells the script what to use as the |'statusline'| setting for NERD tree windows. Note that the statusline is set using |:let-&| not |:set| so escaping spaces isn't necessary. Setting this option to -1 will will deactivate it so that your global statusline setting is used instead. ------------------------------------------------------------------------------ *'NERDTreeWinPos'* Values: "left" or "right" Default: "left". This option is used to determine where NERD tree window is placed on the screen. This option 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 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. The NERD tree API *NERDTreeAPI* The NERD tree script allows you to add custom key mappings and menu items via a set of API calls. Any such scripts should be placed in ~/.vim/nerdtree_plugin/ (*nix) or ~/vimfiles/nerdtree_plugin (windows). ------------------------------------------------------------------------------ 4.1. Key map API *NERDTreeKeymapAPI* NERDTreeAddKeyMap({options}) *NERDTreeAddKeyMap()* Adds a new keymapping for all NERD tree buffers. {options} must be a dictionary, and must contain the following keys: "key" - the shortcut 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-?|) Example: > call NERDTreeAddKeyMap({ \ 'key': 'b', \ 'callback': 'NERDTreeEchoCurrentNode', \ 'quickhelpText': 'echo full path of current node' }) function! NERDTreeEchoCurrentNode() let n = g:NERDTreeFileNode.GetSelected() if n != {} echomsg 'Current node: ' . n.path.str() endif endfunction < This code should sit in a file like ~/.vim/nerdtree_plugin/mymapping.vim. It adds a (rather useless) mapping on 'b' which echos the full path to the current 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 NERD tree 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. ------------------------------------------------------------------------------ NERDTreeRender() *NERDTreeRender()* Re-renders the NERD tree 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 NERD tree 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 msn.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 ;) The latest stable versions can be found at http://www.vim.org/scripts/script.php?script_id=1658 The latest dev versions are on github http://github.com/scrooloose/nerdtree ============================================================================== 6.

See :help NERDTree-A for details. 3.1.1 - fix a bug where a non-listed no-name buffer was getting created every time the tree windows was created, thanks to Derek Wyatt and owen1 - make behave the same as the 'o' mapping - some helptag fixes in the doc, thanks strull - fix a bug when using :set nohidden and opening a file where the previous buf was modified. Thanks iElectric - other minor fixes 3.1.0 New features: - add mappings to open files in a vsplit, see :help NERDTree-s and :help NERDTree-gs - make the statusline for the nerd tree window default to something hopefully more useful. See :help 'NERDTreeStatusline' Bugfixes: - make the hijack netrw functionality work when vim is started with "vim " (thanks to Alf Mikula for the patch). - fix a bug where the CWD wasnt being changed for some operations even when NERDTreeChDirMode==2 (thanks to Lucas S. Buchala) - add -bar to all the nerd tree :commands so they can chain with other :commands (thanks to tpope) - fix bugs when ignorecase was set (thanks to nach) - fix a bug with the relative path code (thanks to nach) - fix a bug where doing a :cd would cause :NERDTreeToggle to fail (thanks nach) 3.0.1 Bugfixes: - fix bugs with :NERDTreeToggle and :NERDTreeMirror when 'hidden was not set - fix a bug where :NERDTree would fail if was relative and didnt start with a ./ or ../ Thanks to James Kanze. - make the q mapping work with secondary (:e style) trees, thanks to jamessan - fix a bunch of small bugs with secondary trees More insane refactoring. 3.0.0 - hijack netrw so that doing an :edit will put a NERD tree in the window rather than a netrw browser.
