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 [<start-directory> | <bookmark>] *:NERDTree* + Opens a fresh NERD tree. The root of the tree depends on the argument + given. There are 3 cases: If no argument is given, the current directory + will be used. If a directory is given, that will be used. If a bookmark + name is given, the corresponding directory will be used. For example: > + :NERDTree /home/marty/vim7/src + :NERDTree foo (foo is the name of a bookmark) +< +:NERDTreeFromBookmark <bookmark> *:NERDTreeFromBookmark* + Opens a fresh NERD tree with the root initialized to the dir for + <bookmark>. This only reason to use this command over :NERDTree is for + the completion (which is for bookmarks rather than directories). + +:NERDTreeToggle [<start-directory> | <bookmark>] *:NERDTreeToggle* + If a NERD tree already exists for this tab, it is reopened and rendered + again. If no NERD tree exists for this tab then this command acts the + same as the |:NERDTree| command. + +:NERDTreeMirror *:NERDTreeMirror* + Shares an existing NERD tree, from another tab, in the current tab. + Changes made to one tree are reflected in both as they are actually the + same buffer. + + If only one other NERD tree exists, that tree is automatically mirrored. If + more than one exists, the script will ask which tree to mirror. + +:NERDTreeClose *:NERDTreeClose* + Close the NERD tree in this tab. + +:NERDTreeFind *:NERDTreeFind* + Find the current file in the tree. If no tree exists for the current tab, + or the file is not under the current root, then initialize a new tree where + the root is the directory of the current file. + +------------------------------------------------------------------------------ +2.2. Bookmarks *NERDTreeBookmarks* + +Bookmarks in the NERD tree are a way to tag files or directories of interest. +For example, you could use bookmarks to tag all of your project directories. + +------------------------------------------------------------------------------ +2.2.1. The Bookmark Table *NERDTreeBookmarkTable* + +If the bookmark table is active (see |NERDTree-B| and +|'NERDTreeShowBookmarks'|), it will be rendered above the tree. You can double +click bookmarks or use the |NERDTree-o| mapping to activate them. See also, +|NERDTree-t| and |NERDTree-T| + +------------------------------------------------------------------------------ +2.2.2. Bookmark commands *NERDTreeBookmarkCommands* + +Note that the following commands are only available in the NERD tree buffer. + +:Bookmark <name> + Bookmark the current node as <name>. If there is already a <name> + bookmark, it is overwritten. <name> must not contain spaces. + +:BookmarkToRoot <bookmark> + Make the directory corresponding to <bookmark> the new root. If a treenode + corresponding to <bookmark> is already cached somewhere in the tree then + the current tree will be used, otherwise a fresh tree will be opened. + Note that if <bookmark> points to a file then its parent will be used + instead. + +:RevealBookmark <bookmark> + If the node is cached under the current root then it will be revealed + (i.e. directory nodes above it will be opened) and the cursor will be + placed on it. + +:OpenBookmark <bookmark> + <bookmark> must point to a file. The file is opened as though |NERDTree-o| + was applied. If the node is cached under the current root then it will be + revealed and the cursor will be placed on it. + +:ClearBookmarks [<bookmarks>] + Remove all the given bookmarks. If no bookmarks are given then remove all + bookmarks on the current node. + +:ClearAllBookmarks + Remove all bookmarks. + +:ReadBookmarks + Re-read the bookmarks in the |'NERDTreeBookmarksFile'|. + +See also |:NERDTree| and |:NERDTreeFromBookmark|. + +------------------------------------------------------------------------------ +2.2.3. Invalid Bookmarks *NERDTreeInvalidBookmarks* + +If invalid bookmarks are detected, the script will issue an error message and +the invalid bookmarks will become unavailable for use. + +These bookmarks will still be stored in the bookmarks file (see +|'NERDTreeBookmarksFile'|), down the bottom. There will always be a blank line +after the valid bookmarks but before the invalid ones. + +Each line in the bookmarks file represents one bookmark. The proper format is: +<bookmark name><space><full path to the bookmark location> + +After you have corrected any invalid bookmarks, either restart vim, or go +:ReadBookmarks from the NERD tree window. + +------------------------------------------------------------------------------ +2.3.

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. + +Toggles whether file filters are used. See |'NERDTreeIgnore'| for details. + +------------------------------------------------------------------------------ + *NERDTree-F* +Default key: F +Map option: NERDTreeMapToggleFiles +Applies to: no restrictions. + +Toggles whether file nodes are displayed. + +------------------------------------------------------------------------------ + *NERDTree-B* +Default key: B +Map option: NERDTreeMapToggleBookmarks +Applies to: no restrictions. + +Toggles whether the bookmarks table is displayed. + +------------------------------------------------------------------------------ + *NERDTree-q* +Default key: q +Map option: NERDTreeMapQuit +Applies to: no restrictions. + +Closes the NERDtree window. + +------------------------------------------------------------------------------ + *NERDTree-A* +Default key: A +Map option: NERDTreeMapToggleZoom +Applies to: no restrictions. + +Maximize (zoom) and minimize the NERDtree window. + +------------------------------------------------------------------------------ + *NERDTree-?* +Default key: ? +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 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. + +Related tags: |NERDTree-m| |NERDTreeApi| + +============================================================================== +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 <some directory> +< +will open up a "secondary" NERD tree instead of a netrw in the target window. + +Secondary NERD trees behaves slighly different from a regular trees in the +following respects: + 1. 'o' will open the selected file in the same window as the tree, + replacing it. + 2. you can have as many secondary tree as you want in the same tab. + +------------------------------------------------------------------------------ + *'NERDTreeIgnore'* +Values: a list of regular expressions. +Default: ['\~$']. + +This option is used to specify which files the NERD tree should ignore. It +must be a list of regular expressions. When the NERD tree is rendered, any +files/dirs that match any of the regex's in 'NERDTreeIgnore' wont be +displayed. + +For example if you put the following line in your vimrc: > + let NERDTreeIgnore=['\.vim$', '\~$'] +< +then all files ending in .vim or ~ will be ignored. + +Note: to tell the NERD tree not to ignore any files you must use the following +line: > + let NERDTreeIgnore=[] +< + +The file filters can be turned on and off dynamically with the |NERDTree-f| +mapping. + +------------------------------------------------------------------------------ + *'NERDTreeBookmarksFile'* +Values: a path +Default: $HOME/.NERDTreeBookmarks + +This is where bookmarks are saved. See |NERDTreeBookmarkCommands|. + +------------------------------------------------------------------------------ + *'NERDTreeMouseMode'* +Values: 1, 2 or 3. +Default: 1. + +If set to 1 then a double click on a node is required to open it. +If set to 2 then a single click will open directory nodes, while a double +click will still be required for file nodes. +If set to 3 then a single click will open any node. + +Note: a double click anywhere on a line that a tree node is on will +activate it, but all single-click activations must be done on name of the node +itself. For example, if you have the following node: > + | | |-application.rb +< +then (to single click activate it) you must click somewhere in +'application.rb'. + +------------------------------------------------------------------------------ + *'NERDTreeQuitOnOpen'* + +Values: 0 or 1. +Default: 0 + +If set to 1, the NERD tree window will close after opening a file with the +|NERDTree-o|, |NERDTree-i|, |NERDTree-t| and |NERDTree-T| 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 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 NERD tree 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-?|) + + 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.
