Todo |taglist-todo| + +============================================================================== + *taglist-intro* +1. Overview~ + +The "Tag List" plugin is a source code browser plugin for Vim. This plugin +allows you to efficiently browse through source code files for different +programming languages. The "Tag List" plugin provides the following features: + + * Displays the tags (functions, classes, structures, variables, etc.) + defined in a file in a vertically or horizontally split Vim window. + * In GUI Vim, optionally displays the tags in the Tags drop-down menu and + in the popup menu. + * Automatically updates the taglist window as you switch between + files/buffers. As you open new files, the tags defined in the new files + are added to the existing file list and the tags defined in all the + files are displayed grouped by the filename. + * When a tag name is selected from the taglist window, positions the + cursor at the definition of the tag in the source file. + * Automatically highlights the current tag name. + * Groups the tags by their type and displays them in a foldable tree. + * Can display the prototype and scope of a tag. + * Can optionally display the tag prototype instead of the tag name in the + taglist window. + * The tag list can be sorted either by name or by chronological order. + * Supports the following language files: Assembly, ASP, Awk, Beta, C, + C++, C#, Cobol, Eiffel, Erlang, Fortran, HTML, Java, Javascript, Lisp, + Lua, Make, Pascal, Perl, PHP, Python, Rexx, Ruby, Scheme, Shell, Slang, + SML, Sql, TCL, Verilog, Vim and Yacc. + * Can be easily extended to support new languages. Support for + existing languages can be modified easily. + * Provides functions to display the current tag name in the Vim status + line or the window title bar. + * The list of tags and files in the taglist can be saved and + restored across Vim sessions. + * Provides commands to get the name and prototype of the current tag. + * Runs in both console/terminal and GUI versions of Vim. + * Works with the winmanager plugin. Using the winmanager plugin, you + can use Vim plugins like the file explorer, buffer explorer and the + taglist plugin at the same time like an IDE. + * Can be used in both Unix and MS-Windows systems. + +============================================================================== + *taglist-internet* +2. Taglist on the internet~ + +The home page of the taglist plugin is at: +> + http://vim-taglist.sourceforge.net/ +< +You can subscribe to the taglist mailing list to post your questions or +suggestions for improvement or to send bug reports. Visit the following page +for subscribing to the mailing list: +> + http://groups.yahoo.com/group/taglist +< +============================================================================== + *taglist-requirements* +3. Requirements~ + +The taglist plugin requires the following: + + * Vim version 6.0 and above + * Exuberant ctags 5.0 and above + +The taglist plugin will work on all the platforms where the exuberant ctags +utility and Vim are supported (this includes MS-Windows and Unix based +systems). + +The taglist plugin relies on the exuberant ctags utility to dynamically +generate the tag listing. The exuberant ctags utility must be installed in +your system to use this plugin. The exuberant ctags utility is shipped with +most of the Linux distributions. You can download the exuberant ctags utility +from +> + http://ctags.sourceforge.net +< +The taglist plugin doesn't use or create a tags file and there is no need to +create a tags file to use this plugin. The taglist plugin will not work with +the GNU ctags or the Unix ctags utility. + +This plugin relies on the Vim "filetype" detection mechanism to determine the +type of the current file. You have to turn on the Vim filetype detection by +adding the following line to your .vimrc file: +> + filetype on +< +The taglist plugin will not work if you run Vim in the restricted mode (using +the -Z command-line argument). + +The taglist plugin uses the Vim system() function to invoke the exuberant +ctags utility. If Vim is compiled without the system() function then you +cannot use the taglist plugin. Some of the Linux distributions (Suse) compile +Vim without the system() function for security reasons. + +============================================================================== + *taglist-install* +4. Installation~ + +1. Download the taglist.zip file and unzip the files to the $HOME/.vim or the + $HOME/vimfiles or the $VIM/vimfiles directory. After this step, you should + have the following two files (the directory structure should be preserved): + + plugin/taglist.vim - main taglist plugin file + doc/taglist.txt - documentation (help) file + + Refer to the |add-plugin|and |'runtimepath'| Vim help pages for more + details about installing Vim plugins. +2. Change to the $HOME/.vim/doc or $HOME/vimfiles/doc or $VIM/vimfiles/doc + directory, start Vim and run the ":helptags ." command to process the + taglist help file. Without this step, you cannot jump to the taglist help + topics. +3. If the exuberant ctags utility is not present in one of the directories in + the PATH environment variable, then set the 'Tlist_Ctags_Cmd' variable to + point to the location of the exuberant ctags utility (not to the directory) + in the .vimrc file. +4. If you are running a terminal/console version of Vim and the terminal + doesn't support changing the window width then set the + 'Tlist_Inc_Winwidth' variable to 0 in the .vimrc file. +5. Restart Vim. +6. You can now use the ":TlistToggle" command to open/close the taglist + window. You can use the ":help taglist" command to get more information + about using the taglist plugin. + +To uninstall the taglist plugin, remove the plugin/taglist.vim and +doc/taglist.txt files from the $HOME/.vim or $HOME/vimfiles directory. + +============================================================================== + *taglist-using* +5. Usage~ + +The taglist plugin can be used in several different ways. + +1. You can keep the taglist window open during the entire editing session. On + opening the taglist window, the tags defined in all the files in the Vim + buffer list will be displayed in the taglist window. As you edit files, the + tags defined in them will be added to the taglist window. You can select a + tag from the taglist window and jump to it. The current tag will be + highlighted in the taglist window. You can close the taglist window when + you no longer need the window. +2. You can configure the taglist plugin to process the tags defined in all the + edited files always. In this configuration, even if the taglist window is + closed and the taglist menu is not displayed, the taglist plugin will + processes the tags defined in newly edited files. You can then open the + taglist window only when you need to select a tag and then automatically + close the taglist window after selecting the tag. +3. You can configure the taglist plugin to display only the tags defined in + the current file in the taglist window. By default, the taglist plugin + displays the tags defined in all the files in the Vim buffer list. As you + switch between files, the taglist window will be refreshed to display only + the tags defined in the current file. +4. In GUI Vim, you can use the Tags pull-down and popup menu created by the + taglist plugin to display the tags defined in the current file and select a + tag to jump to it. You can use the menu without opening the taglist window. + By default, the Tags menu is disabled. +5. You can configure the taglist plugin to display the name of the current tag + in the Vim window status line or in the Vim window title bar. For this to + work without the taglist window or menu, you need to configure the taglist + plugin to process the tags defined in a file always. +6. You can save the tags defined in multiple files to a taglist session file + and load it when needed. You can also configure the taglist plugin to not + update the taglist window when editing new files. You can then manually add + files to the taglist window. + +Opening the taglist window~ +You can open the taglist window using the ":TlistOpen" or the ":TlistToggle" +commands. The ":TlistOpen" command opens the taglist window and jumps to it. +The ":TlistToggle" command opens or closes (toggle) the taglist window and the +cursor remains in the current window. If the 'Tlist_GainFocus_On_ToggleOpen' +variable is set to 1, then the ":TlistToggle" command opens the taglist window +and moves the cursor to the taglist window. + +You can map a key to invoke these commands. For example, the following command +creates a normal mode mapping for the <F8> key to toggle the taglist window. +> + nnoremap <silent> <F8> :TlistToggle<CR> +< +Add the above mapping to your ~/.vimrc or $HOME/_vimrc file. + +To automatically open the taglist window on Vim startup, set the +'Tlist_Auto_Open' variable to 1. + +You can also open the taglist window on startup using the following command +line: +> + $ vim +TlistOpen +< +Closing the taglist window~ +You can close the taglist window from the taglist window by pressing 'q' or +using the Vim ":q" command. You can also use any of the Vim window commands to +close the taglist window. Invoking the ":TlistToggle" command when the taglist +window is opened, closes the taglist window. You can also use the +":TlistClose" command to close the taglist window. + +To automatically close the taglist window when a tag or file is selected, you +can set the 'Tlist_Close_On_Select' variable to 1. To exit Vim when only the +taglist window is present, set the 'Tlist_Exit_OnlyWindow' variable to 1. + +Jumping to a tag or a file~ +You can select a tag in the taglist window either by pressing the <Enter> key +or by double clicking the tag name using the mouse. To jump to a tag on a +single mouse click set the 'Tlist_Use_SingleClick' variable to 1. + +If the selected file is already opened in a window, then the cursor is moved +to that window. If the file is not currently opened in a window then the file +is opened in the window used by the taglist plugin to show the previously +selected file. If there are no usable windows, then the file is opened in a +new window. The file is not opened in special windows like the quickfix +window, preview window and windows containing buffer with the 'buftype' option +set. + +To jump to the tag in a new window, press the 'o' key. To open the file in the +previous window (Ctrl-W_p) use the 'P' key. You can press the 'p' key to jump +to the tag but still keep the cursor in the taglist window (preview). + +To open the selected file in a tab, use the 't' key. If the file is already +present in a tab then the cursor is moved to that tab otherwise the file is +opened in a new tab. To jump to a tag in a new tab press Ctrl-t. The taglist +window is automatically opened in the newly created tab. + +Instead of jumping to a tag, you can open a file by pressing the <Enter> key +or by double clicking the file name using the mouse. + +In the taglist window, you can use the [[ or <Backspace> key to jump to the +beginning of the previous file. You can use the ]] or <Tab> key to jump to the +beginning of the next file. When you reach the first or last file, the search +wraps around and the jumps to the next/previous file. + +Highlighting the current tag~ +The taglist plugin automatically highlights the name of the current tag in the +taglist window. The Vim |CursorHold| autocmd event is used for this. If the +current tag name is not visible in the taglist window, then the taglist window +contents are scrolled to make that tag name visible. You can also use the +":TlistHighlightTag" command to force the highlighting of the current tag. + +The tag name is highlighted if no activity is performed for |'updatetime'| +milliseconds. The default value for this Vim option is 4 seconds. To avoid +unexpected problems, you should not set the |'updatetime'| option to a very +low value. + +To disable the automatic highlighting of the current tag name in the taglist +window, set the 'Tlist_Auto_Highlight_Tag' variable to zero. + +When entering a Vim buffer/window, the taglist plugin automatically highlights +the current tag in that buffer/window. If you like to disable the automatic +highlighting of the current tag when entering a buffer, set the +'Tlist_Highlight_Tag_On_BufEnter' variable to zero. + +Adding files to the taglist~ +When the taglist window is opened, all the files in the Vim buffer list are +processed and the supported files are added to the taglist. When you edit a +file in Vim, the taglist plugin automatically processes this file and adds it +to the taglist. If you close the taglist window, the tag information in the +taglist is retained. + +To process files even when the taglist window is not open, set the +'Tlist_Process_File_Always' variable to 1. + +You can manually add multiple files to the taglist without opening them using +the ":TlistAddFiles" and the ":TlistAddFilesRecursive" commands. + +For example, to add all the C files in the /my/project/dir directory to the +taglist, you can use the following command: +> + :TlistAddFiles /my/project/dir/*.c +< +Note that when adding several files with a large number of tags or a large +number of files, it will take several seconds to several minutes for the +taglist plugin to process all the files. You should not interrupt the taglist +plugin by pressing <CTRL-C>. + +You can recursively add multiple files from a directory tree using the +":TlistAddFilesRecursive" command: +> + :TlistAddFilesRecursive /my/project/dir *.c +< +This command takes two arguments. The first argument specifies the directory +from which to recursively add the files. The second optional argument +specifies the wildcard matching pattern for selecting the files to add. The +default pattern is * and all the files are added. + +Displaying tags for only one file~ +The taglist window displays the tags for all the files in the Vim buffer list +and all the manually added files. To display the tags for only the current +active buffer, set the 'Tlist_Show_One_File' variable to 1. + +Removing files from the taglist~ +You can remove a file from the taglist window, by pressing the 'd' key when the +cursor is on one of the tags listed for the file in the taglist window. The +removed file will no longer be displayed in the taglist window in the current +Vim session. To again display the tags for the file, open the file in a Vim +window and then use the ":TlistUpdate" command or use ":TlistAddFiles" command +to add the file to the taglist. + +When a buffer is removed from the Vim buffer list using the ":bdelete" or the +":bwipeout" command, the taglist is updated to remove the stored information +for this buffer. + +Updating the tags displayed for a file~ +The taglist plugin keeps track of the modification time of a file. When the +modification time changes (the file is modified), the taglist plugin +automatically updates the tags listed for that file. The modification time of +a file is checked when you enter a window containing that file or when you +load that file. + +You can also update or refresh the tags displayed for a file by pressing the +"u" key in the taglist window. If an existing file is modified, after the file +is saved, the taglist plugin automatically updates the tags displayed for the +file. + +You can also use the ":TlistUpdate" command to update the tags for the current +buffer after you made some changes to it. You should save the modified buffer +before you update the taglist window. Otherwise the listed tags will not +include the new tags created in the buffer. + +If you have deleted the tags displayed for a file in the taglist window using +the 'd' key, you can again display the tags for that file using the +":TlistUpdate" command. + +Controlling the taglist updates~ +To disable the automatic processing of new files or modified files, you can +set the 'Tlist_Auto_Update' variable to zero. When this variable is set to +zero, the taglist is updated only when you use the ":TlistUpdate" command or +the ":TlistAddFiles" or the ":TlistAddFilesRecursive" commands. You can use +this option to control which files are added to the taglist. + +You can use the ":TlistLock" command to lock the taglist contents. After this +command is executed, new files are not automatically added to the taglist. +When the taglist is locked, you can use the ":TlistUpdate" command to add the +current file or the ":TlistAddFiles" or ":TlistAddFilesRecursive" commands to +add new files to the taglist. To unlock the taglist, use the ":TlistUnlock" +command. + +Displaying the tag prototype~ +To display the prototype of the tag under the cursor in the taglist window, +press the space bar. If you place the cursor on a tag name in the taglist +window, then the tag prototype is displayed at the Vim status line after +|'updatetime'| milliseconds. The default value for the |'updatetime'| Vim +option is 4 seconds. + +You can get the name and prototype of a tag without opening the taglist window +and the taglist menu using the ":TlistShowTag" and the ":TlistShowPrototype" +commands. These commands will work only if the current file is already present +in the taglist. To use these commands without opening the taglist window, set +the 'Tlist_Process_File_Always' variable to 1. + +You can use the ":TlistShowTag" command to display the name of the tag at or +before the specified line number in the specified file. If the file name and +line number are not supplied, then this command will display the name of the +current tag. For example, +> + :TlistShowTag + :TlistShowTag myfile.java 100 +< +You can use the ":TlistShowPrototype" command to display the prototype of the +tag at or before the specified line number in the specified file. If the file +name and the line number are not supplied, then this command will display the +prototype of the current tag. For example, +> + :TlistShowPrototype + :TlistShowPrototype myfile.c 50 +< +In the taglist window, when the mouse is moved over a tag name, the tag +prototype is displayed in a balloon. This works only in GUI versions where +balloon evaluation is supported. + +Taglist window contents~ +The taglist window contains the tags defined in various files in the taglist +grouped by the filename and by the tag type (variable, function, class, etc.). +For tags with scope information (like class members, structures inside +structures, etc.), the scope information is displayed in square brackets "[]" +after the tag name. + +The contents of the taglist buffer/window are managed by the taglist plugin. +The |'filetype'| for the taglist buffer is set to 'taglist'. The Vim +|'modifiable'| option is turned off for the taglist buffer. You should not +manually edit the taglist buffer, by setting the |'modifiable'| flag. If you +manually edit the taglist buffer contents, then the taglist plugin will be out +of sync with the taglist buffer contents and the plugin will no longer work +correctly. To redisplay the taglist buffer contents again, close the taglist +window and reopen it. + +Opening and closing the tag and file tree~ +In the taglist window, the tag names are displayed as a foldable tree using +the Vim folding support. You can collapse the tree using the '-' key or using +the Vim |zc| fold command. You can open the tree using the '+' key or using +the Vim |zo| fold command. You can open all the folds using the '*' key or +using the Vim |zR| fold command. You can also use the mouse to open/close the +folds. You can close all the folds using the '=' key. You should not manually +create or delete the folds in the taglist window. + +To automatically close the fold for the inactive files/buffers and open only +the fold for the current buffer in the taglist window, set the +'Tlist_File_Fold_Auto_Close' variable to 1. + +Sorting the tags for a file~ +The tags displayed in the taglist window can be sorted either by their name or +by their chronological order. The default sorting method is by the order in +which the tags appear in a file. You can change the default sort method by +setting the 'Tlist_Sort_Type' variable to either "name" or "order". You can +sort the tags by their name by pressing the "s" key in the taglist window. You +can again sort the tags by their chronological order using the "s" key. Each +file in the taglist window can be sorted using different order. + +Zooming in and out of the taglist window~ +You can press the 'x' key in the taglist window to maximize the taglist +window width/height. The window will be maximized to the maximum possible +width/height without closing the other existing windows. You can again press +'x' to restore the taglist window to the default width/height. + + *taglist-session* +Taglist Session~ +A taglist session refers to the group of files and their tags stored in the +taglist in a Vim session. + +You can save and restore a taglist session (and all the displayed tags) using +the ":TlistSessionSave" and ":TlistSessionLoad" commands. + +To save the information about the tags and files in the taglist to a file, use +the ":TlistSessionSave" command and specify the filename: +> + :TlistSessionSave <file name> +< +To load a saved taglist session, use the ":TlistSessionLoad" command: > + + :TlistSessionLoad <file name> +< +When you load a taglist session file, the tags stored in the file will be +added to the tags already stored in the taglist. + +The taglist session feature can be used to save the tags for large files or a +group of frequently used files (like a project). By using the taglist session +file, you can minimize the amount to time it takes to load/refresh the taglist +for multiple files. + +You can create more than one taglist session file for multiple groups of +files. + +Displaying the tag name in the Vim status line or the window title bar~ +You can use the Tlist_Get_Tagname_By_Line() function provided by the taglist +plugin to display the current tag name in the Vim status line or the window +title bar. Similarly, you can use the Tlist_Get_Tag_Prototype_By_Line() +function to display the current tag prototype in the Vim status line or the +window title bar. + +For example, the following command can be used to display the current tag name +in the status line: +> + :set statusline=%<%f%=%([%{Tlist_Get_Tagname_By_Line()}]%) +< +The following command can be used to display the current tag name in the +window title bar: +> + :set title titlestring=%<%f\ %([%{Tlist_Get_Tagname_By_Line()}]%) +< +Note that the current tag name can be displayed only after the file is +processed by the taglist plugin. For this, you have to either set the +'Tlist_Process_File_Always' variable to 1 or open the taglist window or use +the taglist menu. For more information about configuring the Vim status line, +refer to the documentation for the Vim |'statusline'| option. + +Changing the taglist window highlighting~ +The following Vim highlight groups are defined and used to highlight the +various entities in the taglist window: + + TagListTagName - Used for tag names + TagListTagScope - Used for tag scope + TagListTitle - Used for tag titles + TagListComment - Used for comments + TagListFileName - Used for filenames + +By default, these highlight groups are linked to the standard Vim highlight +groups. If you want to change the colors used for these highlight groups, +prefix the highlight group name with 'My' and define it in your .vimrc or +.gvimrc file: MyTagListTagName, MyTagListTagScope, MyTagListTitle, +MyTagListComment and MyTagListFileName. For example, to change the colors +used for tag names, you can use the following command: +> + :highlight MyTagListTagName guifg=blue ctermfg=blue +< +Controlling the taglist window~ +To use a horizontally split taglist window, instead of a vertically split +window, set the 'Tlist_Use_Horiz_Window' variable to 1. + +To use a vertically split taglist window on the rightmost side of the Vim +window, set the 'Tlist_Use_Right_Window' variable to 1. + +You can specify the width of the vertically split taglist window, by setting +the 'Tlist_WinWidth' variable. You can specify the height of the horizontally +split taglist window, by setting the 'Tlist_WinHeight' variable. + +When opening a vertically split taglist window, the Vim window width is +increased to accommodate the new taglist window. When the taglist window is +closed, the Vim window is reduced. To disable this, set the +'Tlist_Inc_Winwidth' variable to zero. + +To reduce the number of empty lines in the taglist window, set the +'Tlist_Compact_Format' variable to 1. + +To not display the Vim fold column in the taglist window, set the +'Tlist_Enable_Fold_Column' variable to zero. + +To display the tag prototypes instead of the tag names in the taglist window, +set the 'Tlist_Display_Prototype' variable to 1. + +To not display the scope of the tags next to the tag names, set the +'Tlist_Display_Tag_Scope' variable to zero. + + *taglist-keys* +Taglist window key list~ +The following table lists the description of the keys that can be used +in the taglist window. + + Key Description~ + + <CR> Jump to the location where the tag under cursor is + defined. + o Jump to the location where the tag under cursor is + defined in a new window. + P Jump to the tag in the previous (Ctrl-W_p) window. + p Display the tag definition in the file window and + keep the cursor in the taglist window itself. + t Jump to the tag in a new tab. If the file is already + opened in a tab, move to that tab. + Ctrl-t Jump to the tag in a new tab. + <Space> Display the prototype of the tag under the cursor. + For file names, display the full path to the file, + file type and the number of tags. For tag types, display the + tag type and the number of tags. + u Update the tags listed in the taglist window + s Change the sort order of the tags (by name or by order) + d Remove the tags for the file under the cursor + x Zoom-in or Zoom-out the taglist window + + Open a fold + - Close a fold + * Open all folds + = Close all folds + [[ Jump to the beginning of the previous file + <Backspace> Jump to the beginning of the previous file + ]] Jump to the beginning of the next file + <Tab> Jump to the beginning of the next file + q Close the taglist window + <F1> Display help + +The above keys will work in both the normal mode and the insert mode. + + *taglist-menu* +Taglist menu~ +When using GUI Vim, the taglist plugin can display the tags defined in the +current file in the drop-down menu and the popup menu. By default, this +feature is turned off. To turn on this feature, set the 'Tlist_Show_Menu' +variable to 1. + +You can jump to a tag by selecting the tag name from the menu. You can use the +taglist menu independent of the taglist window i.e. you don't need to open the +taglist window to get the taglist menu. + +When you switch between files/buffers, the taglist menu is automatically +updated to display the tags defined in the current file/buffer. + +The tags are grouped by their type (variables, functions, classes, methods, +etc.) and displayed as a separate sub-menu for each type. If all the tags +defined in a file are of the same type (e.g. functions), then the sub-menu is +not used. + +If the number of items in a tag type submenu exceeds the value specified by +the 'Tlist_Max_Submenu_Items' variable, then the submenu will be split into +multiple submenus. The default setting for 'Tlist_Max_Submenu_Items' is 25. +The first and last tag names in the submenu are used to form the submenu name. +The menu items are prefixed by alpha-numeric characters for easy selection by +keyboard. + +If the popup menu support is enabled (the |'mousemodel'| option contains +"popup"), then the tags menu is added to the popup menu. You can access +the popup menu by right clicking on the GUI window. + +You can regenerate the tags menu by selecting the 'Tags->Refresh menu' entry. +You can sort the tags listed in the menu either by name or by order by +selecting the 'Tags->Sort menu by->Name/Order' menu entry. + +You can tear-off the Tags menu and keep it on the side of the Vim window +for quickly locating the tags. + +Using the taglist plugin with the winmanager plugin~ +You can use the taglist plugin with the winmanager plugin. This will allow you +to use the file explorer, buffer explorer and the taglist plugin at the same +time in different windows. To use the taglist plugin with the winmanager +plugin, set 'TagList' in the 'winManagerWindowLayout' variable. For example, +to use the file explorer plugin and the taglist plugin at the same time, use +the following setting: > + + let winManagerWindowLayout = 'FileExplorer|TagList' +< +Getting help~ +If you have installed the taglist help file (this file), then you can use the +Vim ":help taglist-<keyword>" command to get help on the various taglist +topics. + +You can press the <F1> key in the taglist window to display the help +information about using the taglist window. If you again press the <F1> key, +the help information is removed from the taglist window. + + *taglist-debug* +Debugging the taglist plugin~ +You can use the ":TlistDebug" command to enable logging of the debug messages +from the taglist plugin. To display the logged debug messages, you can use the +":TlistMessages" command. To disable the logging of the debug messages, use +the ":TlistUndebug" command. + +You can specify a file name to the ":TlistDebug" command to log the debug +messages to a file. Otherwise, the debug messages are stored in a script-local +variable. In the later case, to minimize memory usage, only the last 3000 +characters from the debug messages are stored. + +============================================================================== + *taglist-options* +6. Options~ + +A number of Vim variables control the behavior of the taglist plugin. These +variables are initialized to a default value. By changing these variables you +can change the behavior of the taglist plugin. You need to change these +settings only if you want to change the behavior of the taglist plugin. You +should use the |:let| command in your .vimrc file to change the setting of any +of these variables. + +The configurable taglist variables are listed below. For a detailed +description of these variables refer to the text below this table. + +|'Tlist_Auto_Highlight_Tag'| Automatically highlight the current tag in the + taglist. +|'Tlist_Auto_Open'| Open the taglist window when Vim starts. +|'Tlist_Auto_Update'| Automatically update the taglist to include + newly edited files. +|'Tlist_Close_On_Select'| Close the taglist window when a file or tag is + selected. +|'Tlist_Compact_Format'| Remove extra information and blank lines from + the taglist window. +|'Tlist_Ctags_Cmd'| Specifies the path to the ctags utility. +|'Tlist_Display_Prototype'| Show prototypes and not tags in the taglist + window. +|'Tlist_Display_Tag_Scope'| Show tag scope next to the tag name. +|'Tlist_Enable_Fold_Column'| Show the fold indicator column in the taglist + window. +|'Tlist_Exit_OnlyWindow'| Close Vim if the taglist is the only window. +|'Tlist_File_Fold_Auto_Close'| Close tag folds for inactive buffers. +|'Tlist_GainFocus_On_ToggleOpen'| + Jump to taglist window on open. +|'Tlist_Highlight_Tag_On_BufEnter'| + On entering a buffer, automatically highlight + the current tag. +|'Tlist_Inc_Winwidth'| Increase the Vim window width to accommodate + the taglist window. +|'Tlist_Max_Submenu_Items'| Maximum number of items in a tags sub-menu. +|'Tlist_Max_Tag_Length'| Maximum tag length used in a tag menu entry. +|'Tlist_Process_File_Always'| Process files even when the taglist window is + closed. +|'Tlist_Show_Menu'| Display the tags menu. +|'Tlist_Show_One_File'| Show tags for the current buffer only. +|'Tlist_Sort_Type'| Sort method used for arranging the tags. +|'Tlist_Use_Horiz_Window'| Use a horizontally split window for the + taglist window. +|'Tlist_Use_Right_Window'| Place the taglist window on the right side. +|'Tlist_Use_SingleClick'| Single click on a tag jumps to it. +|'Tlist_WinHeight'| Horizontally split taglist window height. +|'Tlist_WinWidth'| Vertically split taglist window width. + + *'Tlist_Auto_Highlight_Tag'* +Tlist_Auto_Highlight_Tag~ +The taglist plugin will automatically highlight the current tag in the taglist +window. If you want to disable this, then you can set the +'Tlist_Auto_Highlight_Tag' variable to zero. Note that even though the current +tag highlighting is disabled, the tags for a new file will still be added to +the taglist window. +> + let Tlist_Auto_Highlight_Tag = 0 +< +With the above variable set to 1, you can use the ":TlistHighlightTag" command +to highlight the current tag. + + *'Tlist_Auto_Open'* +Tlist_Auto_Open~ +To automatically open the taglist window, when you start Vim, you can set the +'Tlist_Auto_Open' variable to 1. By default, this variable is set to zero and +the taglist window will not be opened automatically on Vim startup. +> + let Tlist_Auto_Open = 1 +< +The taglist window is opened only when a supported type of file is opened on +Vim startup. For example, if you open text files, then the taglist window will +not be opened. + + *'Tlist_Auto_Update'* +Tlist_Auto_Update~ +When a new file is edited, the tags defined in the file are automatically +processed and added to the taglist. To stop adding new files to the taglist, +set the 'Tlist_Auto_Update' variable to zero. By default, this variable is set +to 1. +> + let Tlist_Auto_Update = 0 +< +With the above variable set to 1, you can use the ":TlistUpdate" command to +add the tags defined in the current file to the taglist. + + *'Tlist_Close_On_Select'* +Tlist_Close_On_Select~ +If you want to close the taglist window when a file or tag is selected, then +set the 'Tlist_Close_On_Select' variable to 1. By default, this variable is +set zero and when you select a tag or file from the taglist window, the window +is not closed. +> + let Tlist_Close_On_Select = 1 +< + *'Tlist_Compact_Format'* +Tlist_Compact_Format~ +By default, empty lines are used to separate different tag types displayed for +a file and the tags displayed for different files in the taglist window. If +you want to display as many tags as possible in the taglist window, you can +set the 'Tlist_Compact_Format' variable to 1 to get a compact display. +> + let Tlist_Compact_Format = 1 +< + *'Tlist_Ctags_Cmd'* +Tlist_Ctags_Cmd~ +The 'Tlist_Ctags_Cmd' variable specifies the location (path) of the exuberant +ctags utility. If exuberant ctags is present in any one of the directories in +the PATH environment variable, then there is no need to set this variable. + +The exuberant ctags tool can be installed under different names. When the +taglist plugin starts up, if the 'Tlist_Ctags_Cmd' variable is not set, it +checks for the names exuberant-ctags, exctags, ctags, ctags.exe and tags in +the PATH environment variable. If any one of the named executable is found, +then the Tlist_Ctags_Cmd variable is set to that name. + +If exuberant ctags is not present in one of the directories specified in the +PATH environment variable, then set this variable to point to the location of +the ctags utility in your system. Note that this variable should point to the +fully qualified exuberant ctags location and NOT to the directory in which +exuberant ctags is installed. If the exuberant ctags tool is not found in +either PATH or in the specified location, then the taglist plugin will not be +loaded. Examples: +> + let Tlist_Ctags_Cmd = 'd:\tools\ctags.exe' + let Tlist_Ctags_Cmd = '/usr/local/bin/ctags' +< + *'Tlist_Display_Prototype'* +Tlist_Display_Prototype~ +By default, only the tag name will be displayed in the taglist window. If you +like to see tag prototypes instead of names, set the 'Tlist_Display_Prototype' +variable to 1. By default, this variable is set to zero and only tag names +will be displayed. +> + let Tlist_Display_Prototype = 1 +< + *'Tlist_Display_Tag_Scope'* +Tlist_Display_Tag_Scope~ +By default, the scope of a tag (like a C++ class) will be displayed in +square brackets next to the tag name. If you don't want the tag scopes +to be displayed, then set the 'Tlist_Display_Tag_Scope' to zero. By default, +this variable is set to 1 and the tag scopes will be displayed. +> + let Tlist_Display_Tag_Scope = 0 +< + *'Tlist_Enable_Fold_Column'* +Tlist_Enable_Fold_Column~ +By default, the Vim fold column is enabled and displayed in the taglist +window. If you wish to disable this (for example, when you are working with a +narrow Vim window or terminal), you can set the 'Tlist_Enable_Fold_Column' +variable to zero. +> + let Tlist_Enable_Fold_Column = 1 +< + *'Tlist_Exit_OnlyWindow'* +Tlist_Exit_OnlyWindow~ +If you want to exit Vim if only the taglist window is currently opened, then +set the 'Tlist_Exit_OnlyWindow' variable to 1. By default, this variable is +set to zero and the Vim instance will not be closed if only the taglist window +is present. +> + let Tlist_Exit_OnlyWindow = 1 +< + *'Tlist_File_Fold_Auto_Close'* +Tlist_File_Fold_Auto_Close~ +By default, the tags tree displayed in the taglist window for all the files is +opened. You can close/fold the tags tree for the files manually. To +automatically close the tags tree for inactive files, you can set the +'Tlist_File_Fold_Auto_Close' variable to 1. When this variable is set to 1, +the tags tree for the current buffer is automatically opened and for all the +other buffers is closed. +> + let Tlist_File_Fold_Auto_Close = 1 +< + *'Tlist_GainFocus_On_ToggleOpen'* +Tlist_GainFocus_On_ToggleOpen~ +When the taglist window is opened using the ':TlistToggle' command, this +option controls whether the cursor is moved to the taglist window or remains +in the current window. By default, this option is set to 0 and the cursor +remains in the current window. When this variable is set to 1, the cursor +moves to the taglist window after opening the taglist window. +> + let Tlist_GainFocus_On_ToggleOpen = 1 +< + *'Tlist_Highlight_Tag_On_BufEnter'* +Tlist_Highlight_Tag_On_BufEnter~ +When you enter a Vim buffer/window, the current tag in that buffer/window is +automatically highlighted in the taglist window. If the current tag name is +not visible in the taglist window, then the taglist window contents are +scrolled to make that tag name visible. If you like to disable the automatic +highlighting of the current tag when entering a buffer, you can set the +'Tlist_Highlight_Tag_On_BufEnter' variable to zero. The default setting for +this variable is 1. +> + let Tlist_Highlight_Tag_On_BufEnter = 0 +< + *'Tlist_Inc_Winwidth'* +Tlist_Inc_Winwidth~ +By default, when the width of the window is less than 100 and a new taglist +window is opened vertically, then the window width is increased by the value +set in the 'Tlist_WinWidth' variable to accommodate the new window. The value +of this variable is used only if you are using a vertically split taglist +window. + +If your terminal doesn't support changing the window width from Vim (older +version of xterm running in a Unix system) or if you see any weird problems in +the screen due to the change in the window width or if you prefer not to +adjust the window width then set the 'Tlist_Inc_Winwidth' variable to zero. +CAUTION: If you are using the MS-Windows version of Vim in a MS-DOS command +window then you must set this variable to zero, otherwise the system may hang +due to a Vim limitation (explained in :help win32-problems) +> + let Tlist_Inc_Winwidth = 0 +< + *'Tlist_Max_Submenu_Items'* +Tlist_Max_Submenu_Items~ +If a file contains too many tags of a particular type (function, variable, +class, etc.), greater than that specified by the 'Tlist_Max_Submenu_Items' +variable, then the menu for that tag type will be split into multiple +sub-menus. The default setting for the 'Tlist_Max_Submenu_Items' variable is +25. This can be changed by setting the 'Tlist_Max_Submenu_Items' variable: +> + let Tlist_Max_Submenu_Items = 20 +< +The name of the submenu is formed using the names of the first and the last +tag entries in that submenu. + + *'Tlist_Max_Tag_Length'* +Tlist_Max_Tag_Length~ +Only the first 'Tlist_Max_Tag_Length' characters from the tag names will be +used to form the tag type submenu name. The default value for this variable is +10. Change the 'Tlist_Max_Tag_Length' setting if you want to include more or +less characters: +> + let Tlist_Max_Tag_Length = 10 +< + *'Tlist_Process_File_Always'* +Tlist_Process_File_Always~ +By default, the taglist plugin will generate and process the tags defined in +the newly opened files only when the taglist window is opened or when the +taglist menu is enabled. When the taglist window is closed, the taglist plugin +will stop processing the tags for newly opened files. + +You can set the 'Tlist_Process_File_Always' variable to 1 to generate the list +of tags for new files even when the taglist window is closed and the taglist +menu is disabled. +> + let Tlist_Process_File_Always = 1 +< +To use the ":TlistShowTag" and the ":TlistShowPrototype" commands without the +taglist window and the taglist menu, you should set this variable to 1. + + *'Tlist_Show_Menu'* +Tlist_Show_Menu~ +When using GUI Vim, you can display the tags defined in the current file in a +menu named "Tags". By default, this feature is turned off. To turn on this +feature, set the 'Tlist_Show_Menu' variable to 1: +> + let Tlist_Show_Menu = 1 +< + *'Tlist_Show_One_File'* +Tlist_Show_One_File~ +By default, the taglist plugin will display the tags defined in all the loaded +buffers in the taglist window. If you prefer to display the tags defined only +in the current buffer, then you can set the 'Tlist_Show_One_File' to 1. When +this variable is set to 1, as you switch between buffers, the taglist window +will be refreshed to display the tags for the current buffer and the tags for +the previous buffer will be removed. +> + let Tlist_Show_One_File = 1 +< + *'Tlist_Sort_Type'* +Tlist_Sort_Type~ +The 'Tlist_Sort_Type' variable specifies the sort order for the tags in the +taglist window. The tags can be sorted either alphabetically by their name or +by the order of their appearance in the file (chronological order). By +default, the tag names will be listed by the order in which they are defined +in the file. You can change the sort type (from name to order or from order to +name) by pressing the "s" key in the taglist window. You can also change the +default sort order by setting 'Tlist_Sort_Type' to "name" or "order": +> + let Tlist_Sort_Type = "name" +< + *'Tlist_Use_Horiz_Window'* +Tlist_Use_Horiz_Window~ +Be default, the tag names are displayed in a vertically split window. If you +prefer a horizontally split window, then set the 'Tlist_Use_Horiz_Window' +variable to 1. If you are running MS-Windows version of Vim in a MS-DOS +command window, then you should use a horizontally split window instead of a +vertically split window. Also, if you are using an older version of xterm in a +Unix system that doesn't support changing the xterm window width, you should +use a horizontally split window. +> + let Tlist_Use_Horiz_Window = 1 +< + *'Tlist_Use_Right_Window'* +Tlist_Use_Right_Window~ +By default, the vertically split taglist window will appear on the left hand +side. If you prefer to open the window on the right hand side, you can set the +'Tlist_Use_Right_Window' variable to 1: +> + let Tlist_Use_Right_Window = 1 +< + *'Tlist_Use_SingleClick'* +Tlist_Use_SingleClick~ +By default, when you double click on the tag name using the left mouse +button, the cursor will be positioned at the definition of the tag. You +can set the 'Tlist_Use_SingleClick' variable to 1 to jump to a tag when +you single click on the tag name using the mouse. By default this variable +is set to zero. +> + let Tlist_Use_SingleClick = 1 +< +Due to a bug in Vim, if you set 'Tlist_Use_SingleClick' to 1 and try to resize +the taglist window using the mouse, then Vim will crash. This problem is fixed +in Vim 6.3 and above. In the meantime, instead of resizing the taglist window +using the mouse, you can use normal Vim window resizing commands to resize the +taglist window. + + *'Tlist_WinHeight'* +Tlist_WinHeight~ +The default height of the horizontally split taglist window is 10. This can be +changed by modifying the 'Tlist_WinHeight' variable: +> + let Tlist_WinHeight = 20 +< +The |'winfixheight'| option is set for the taglist window, to maintain the +height of the taglist window, when new Vim windows are opened and existing +windows are closed. + + *'Tlist_WinWidth'* +Tlist_WinWidth~ +The default width of the vertically split taglist window is 30. This can be +changed by modifying the 'Tlist_WinWidth' variable: +> + let Tlist_WinWidth = 20 +< +Note that the value of the |'winwidth'| option setting determines the minimum +width of the current window. If you set the 'Tlist_WinWidth' variable to a +value less than that of the |'winwidth'| option setting, then Vim will use the +value of the |'winwidth'| option. + +When new Vim windows are opened and existing windows are closed, the taglist +plugin will try to maintain the width of the taglist window to the size +specified by the 'Tlist_WinWidth' variable. + +============================================================================== + *taglist-commands* +7. Commands~ + +The taglist plugin provides the following ex-mode commands: + +|:TlistAddFiles| Add multiple files to the taglist. +|:TlistAddFilesRecursive| + Add files recursively to the taglist. +|:TlistClose| Close the taglist window. +|:TlistDebug| Start logging of taglist debug messages. +|:TlistLock| Stop adding new files to the taglist. +|:TlistMessages| Display the logged taglist plugin debug messages. +|:TlistOpen| Open and jump to the taglist window. +|:TlistSessionSave| Save the information about files and tags in the + taglist to a session file. +|:TlistSessionLoad| Load the information about files and tags stored + in a session file to taglist. +|:TlistShowPrototype| Display the prototype of the tag at or before the + specified line number. +|:TlistShowTag| Display the name of the tag defined at or before the + specified line number. +|:TlistHighlightTag| Highlight the current tag in the taglist window. +|:TlistToggle| Open or close (toggle) the taglist window. +|:TlistUndebug| Stop logging of taglist debug messages. +|:TlistUnlock| Start adding new files to the taglist. +|:TlistUpdate| Update the tags for the current buffer. + + *:TlistAddFiles* +:TlistAddFiles {file(s)} [file(s) ...] + Add one or more specified files to the taglist. You can + specify multiple filenames using wildcards. To specify a + file name with space character, you should escape the space + character with a backslash. + Examples: +> + :TlistAddFiles *.c *.cpp + :TlistAddFiles file1.html file2.html +< + If you specify a large number of files, then it will take some + time for the taglist plugin to process all of them. The + specified files will not be edited in a Vim window and will + not be added to the Vim buffer list. + + *:TlistAddFilesRecursive* +:TlistAddFilesRecursive {directory} [ {pattern} ] + Add files matching {pattern} recursively from the specified + {directory} to the taglist. If {pattern} is not specified, + then '*' is assumed. To specify the current directory, use "." + for {directory}. To specify a directory name with space + character, you should escape the space character with a + backslash. + Examples: +> + :TlistAddFilesRecursive myproject *.java + :TlistAddFilesRecursive smallproject +< + If large number of files are present in the specified + directory tree, then it will take some time for the taglist + plugin to process all of them. + + *:TlistClose* +:TlistClose Close the taglist window. This command can be used from any + one of the Vim windows. + + *:TlistDebug* +:TlistDebug [filename] + Start logging of debug messages from the taglist plugin. + If {filename} is specified, then the debug messages are stored + in the specified file. Otherwise, the debug messages are + stored in a script local variable. If the file {filename} is + already present, then it is overwritten. + + *:TlistLock* +:TlistLock + Lock the taglist and don't process new files. After this + command is executed, newly edited files will not be added to + the taglist. + + *:TlistMessages* +:TlistMessages + Display the logged debug messages from the taglist plugin + in a window. This command works only when logging to a + script-local variable. + + *:TlistOpen* +:TlistOpen Open and jump to the taglist window. Creates the taglist + window, if the window is not opened currently. After executing + this command, the cursor is moved to the taglist window. When + the taglist window is opened for the first time, all the files + in the buffer list are processed and the tags defined in them + are displayed in the taglist window. + + *:TlistSessionSave* +:TlistSessionSave {filename} + Saves the information about files and tags in the taglist to + the specified file. This command can be used to save and + restore the taglist contents across Vim sessions. + + *:TlistSessionLoad* +:TlistSessionLoad {filename} + Load the information about files and tags stored in the + specified session file to the taglist. + + *:TlistShowPrototype* +:TlistShowPrototype [filename] [linenumber] + Display the prototype of the tag at or before the specified + line number. If the file name and the line number are not + specified, then the current file name and line number are + used. A tag spans multiple lines starting from the line where + it is defined to the line before the next tag. This command + displays the prototype for the tag for any line number in this + range. + + *:TlistShowTag* +:TlistShowTag [filename] [linenumber] + Display the name of the tag defined at or before the specified + line number. If the file name and the line number are not + specified, then the current file name and line number are + used. A tag spans multiple lines starting from the line where + it is defined to the line before the next tag. This command + displays the tag name for any line number in this range. + + *:TlistHighlightTag* +:TlistHighlightTag + Highlight the current tag in the taglist window. By default, + the taglist plugin periodically updates the taglist window to + highlight the current tag. This command can be used to force + the taglist plugin to highlight the current tag. + + *:TlistToggle* +:TlistToggle Open or close (toggle) the taglist window. Opens the taglist + window, if the window is not opened currently. Closes the + taglist window, if the taglist window is already opened. When + the taglist window is opened for the first time, all the files + in the buffer list are processed and the tags are displayed in + the taglist window. After executing this command, the cursor + is not moved from the current window to the taglist window. + + *:TlistUndebug* +:TlistUndebug + Stop logging of debug messages from the taglist plugin. + + *:TlistUnlock* +:TlistUnlock + Unlock the taglist and start processing newly edited files. + + *:TlistUpdate* +:TlistUpdate Update the tags information for the current buffer. This + command can be used to re-process the current file/buffer and + get the tags information. As the taglist plugin uses the file + saved in the disk (instead of the file displayed in a Vim + buffer), you should save a modified buffer before you update + the taglist. Otherwise the listed tags will not include the + new tags created in the buffer. You can use this command even + when the taglist window is not opened. + +============================================================================== + *taglist-functions* +8. Global functions~ + +The taglist plugin provides several global functions that can be used from +other Vim plugins to interact with the taglist plugin. These functions are +described below. + +|Tlist_Update_File_Tags()| Update the tags for the specified file +|Tlist_Get_Tag_Prototype_By_Line()| Return the prototype of the tag at or + before the specified line number in the + specified file. +|Tlist_Get_Tagname_By_Line()| Return the name of the tag at or + before the specified line number in + the specified file. +|Tlist_Set_App()| Set the name of the application + controlling the taglist window. + + *Tlist_Update_File_Tags()* +Tlist_Update_File_Tags({filename}, {filetype}) + Update the tags for the file {filename}. The second argument + specifies the Vim filetype for the file. If the taglist plugin + has not processed the file previously, then the exuberant + ctags tool is invoked to generate the tags for the file. + + *Tlist_Get_Tag_Prototype_By_Line()* +Tlist_Get_Tag_Prototype_By_Line([{filename}, {linenumber}]) + Return the prototype of the tag at or before the specified + line number in the specified file. If the filename and line + number are not specified, then the current buffer name and the + current line number are used. + + *Tlist_Get_Tagname_By_Line()* +Tlist_Get_Tagname_By_Line([{filename}, {linenumber}]) + Return the name of the tag at or before the specified line + number in the specified file. If the filename and line number + are not specified, then the current buffer name and the + current line number are used. + + *Tlist_Set_App()* +Tlist_Set_App({appname}) + Set the name of the plugin that controls the taglist plugin + window and buffer. This can be used to integrate the taglist + plugin with other Vim plugins. + + For example, the winmanager plugin and the Cream package use + this function and specify the appname as "winmanager" and + "cream" respectively. + + By default, the taglist plugin is a stand-alone plugin and + controls the taglist window and buffer. If the taglist window + is controlled by an external plugin, then the appname should + be set appropriately. + +============================================================================== + *taglist-extend* +9. Extending~ + +The taglist plugin supports all the languages supported by the exuberant ctags +tool, which includes the following languages: Assembly, ASP, Awk, Beta, C, +C++, C#, Cobol, Eiffel, Erlang, Fortran, HTML, Java, Javascript, Lisp, Lua, +Make, Pascal, Perl, PHP, Python, Rexx, Ruby, Scheme, Shell, Slang, SML, Sql, +TCL, Verilog, Vim and Yacc. + +You can extend the taglist plugin to add support for new languages and also +modify the support for the above listed languages. + +You should NOT make modifications to the taglist plugin script file to add +support for new languages. You will lose these changes when you upgrade to the +next version of the taglist plugin. Instead you should follow the below +described instructions to extend the taglist plugin. + +You can extend the taglist plugin by setting variables in the .vimrc or _vimrc +file. The name of these variables depends on the language name and is +described below. + +Modifying support for an existing language~ +To modify the support for an already supported language, you have to set the +tlist_xxx_settings variable in the ~/.vimrc or $HOME/_vimrc file. Replace xxx +with the Vim filetype name for the language file. For example, to modify the +support for the perl language files, you have to set the tlist_perl_settings +variable. To modify the support for java files, you have to set the +tlist_java_settings variable. + +To determine the filetype name used by Vim for a file, use the following +command in the buffer containing the file: + + :set filetype + +The above command will display the Vim filetype for the current buffer. + +The format of the value set in the tlist_xxx_settings variable is + + <language_name>;flag1:name1;flag2:name2;flag3:name3 + +The different fields in the value are separated by the ';' character. + +The first field 'language_name' is the name used by exuberant ctags to refer +to this language file. This name can be different from the file type name used +by Vim. For example, for C++, the language name used by ctags is 'c++' but the +filetype name used by Vim is 'cpp'. To get the list of language names +supported by exuberant ctags, use the following command: + + $ ctags --list-maps=all + +The remaining fields follow the format "flag:name". The sub-field 'flag' is +the language specific flag used by exuberant ctags to generate the +corresponding tags. For example, for the C language, to list only the +functions, the 'f' flag is used. To get the list of flags supported by +exuberant ctags for the various languages use the following command: + + $ ctags --list-kinds=all + +The sub-field 'name' specifies the title text to use for displaying the tags +of a particular type. For example, 'name' can be set to 'functions'. This +field can be set to any text string name. + +For example, to list only the classes and functions defined in a C++ language +file, add the following line to your .vimrc file: + + let tlist_cpp_settings = 'c++;c:class;f:function' + +In the above setting, 'cpp' is the Vim filetype name and 'c++' is the name +used by the exuberant ctags tool. 'c' and 'f' are the flags passed to +exuberant ctags to list C++ classes and functions and 'class' is the title +used for the class tags and 'function' is the title used for the function tags +in the taglist window. + +For example, to display only functions defined in a C file and to use "My +Functions" as the title for the function tags, use + + let tlist_c_settings = 'c;f:My Functions' + +When you set the tlist_xxx_settings variable, you will override the default +setting used by the taglist plugin for the 'xxx' language. You cannot add to +the default options used by the taglist plugin for a particular file type. To +add to the options used by the taglist plugin for a language, copy the option +values from the taglist plugin file to your .vimrc file and modify it. + +Adding support for a new language~ +If you want to add support for a new language to the taglist plugin, you need +to first extend the exuberant ctags tool. For more information about extending +exuberant ctags, visit the following page: + + http://ctags.sourceforge.net/EXTENDING.html + +To add support for a new language, set the tlist_xxx_settings variable in the +~/.vimrc file appropriately as described above. Replace 'xxx' in the variable +name with the Vim filetype name for the new language. + +For example, to extend the taglist plugin to support the latex language, you +can use the following line (assuming, you have already extended exuberant +ctags to support the latex language): + + let tlist_tex_settings='latex;b:bibitem;c:command;l:label' + +With the above line, when you edit files of filetype "tex" in Vim, the taglist +plugin will invoke the exuberant ctags tool passing the "latex" filetype and +the flags b, c and l to generate the tags. The text heading 'bibitem', +'command' and 'label' will be used in the taglist window for the tags which +are generated for the flags b, c and l respectively. + +============================================================================== + *taglist-faq* +10. Frequently Asked Questions~ + +Q. The taglist plugin doesn't work. The taglist window is empty and the tags + defined in a file are not displayed. +A. Are you using Vim version 6.0 and above? The taglist plugin relies on the + features supported by Vim version 6.0 and above. You can use the following + command to get the Vim version: +> + $ vim --version +< + Are you using exuberant ctags version 5.0 and above? The taglist plugin + relies on the features supported by exuberant ctags and will not work with + GNU ctags or the Unix ctags utility. You can use the following command to + determine whether the ctags installed in your system is exuberant ctags: +> + $ ctags --version +< + Is exuberant ctags present in one of the directories in your PATH? If not, + you need to set the Tlist_Ctags_Cmd variable to point to the location of + exuberant ctags. Use the following Vim command to verify that this is setup + correctly: +> + :echo system(Tlist_Ctags_Cmd . ' --version') +< + The above command should display the version information for exuberant + ctags. + + Did you turn on the Vim filetype detection? The taglist plugin relies on + the filetype detected by Vim and passes the filetype to the exuberant ctags + utility to parse the tags. Check the output of the following Vim command: +> + :filetype +< + The output of the above command should contain "filetype detection:ON". + To turn on the filetype detection, add the following line to the .vimrc or + _vimrc file: +> + filetype on +< + Is your version of Vim compiled with the support for the system() function? + The following Vim command should display 1: +> + :echo exists('*system') +< + In some Linux distributions (particularly Suse Linux), the default Vim + installation is built without the support for the system() function. The + taglist plugin uses the system() function to invoke the exuberant ctags + utility. You need to rebuild Vim after enabling the support for the + system() function. If you use the default build options, the system() + function will be supported. + + Do you have the |'shellslash'| option set? You can try disabling the + |'shellslash'| option. When the taglist plugin invokes the exuberant ctags + utility with the path to the file, if the incorrect slashes are used, then + you will see errors. + + Check the shell related Vim options values using the following command: +> + :set shell? shellcmdflag? shellpipe? + :set shellquote? shellredir? shellxquote? +< + If these options are set in your .vimrc or _vimrc file, try removing those + lines. + + Are you using a Unix shell in a MS-Windows environment? For example, + the Unix shell from the MKS-toolkit. Do you have the SHELL environment + set to point to this shell? You can try resetting the SHELL environment + variable. + + If you are using a Unix shell on MS-Windows, you should try to use + exuberant ctags that is compiled for Unix-like environments so that + exuberant ctags will understand path names with forward slash characters. + + Is your filetype supported by the exuberant ctags utility? The file types + supported by the exuberant ctags utility are listed in the ctags help. If a + file type is not supported, you have to extend exuberant ctags. You can use + the following command to list the filetypes supported by exuberant ctags: +> + ctags --list-languages +< + Run the following command from the shell prompt and check whether the tags + defined in your file are listed in the output from exuberant ctags: +> + ctags -f - --format=2 --excmd=pattern --fields=nks <filename> +< + If you see your tags in the output from the above command, then the + exuberant ctags utility is properly parsing your file. + + Do you have the .ctags or _ctags or the ctags.cnf file in your home + directory for specifying default options or for extending exuberant ctags? + If you do have this file, check the options in this file and make sure + these options are not interfering with the operation of the taglist plugin. + + If you are using MS-Windows, check the value of the TEMP and TMP + environment variables. If these environment variables are set to a path + with space characters in the name, then try using the DOS 8.3 short name + for the path or set them to a path without the space characters in the + name. For example, if the temporary directory name is "C:\Documents and + Settings\xyz\Local Settings\Temp", then try setting the TEMP variable to + the following: +> + set TEMP=C:\DOCUMEN~1\xyz\LOCALS~1\Temp +< + If exuberant ctags is installed in a directory with space characters in the + name, then try adding the directory to the PATH environment variable or try + setting the 'Tlist_Ctags_Cmd' variable to the shortest path name to ctags + or try copying the exuberant ctags to a path without space characters in + the name. For example, if exuberant ctags is installed in the directory + "C:\Program Files\Ctags", then try setting the 'Tlist_Ctags_Cmd' variable + as below: +> + let Tlist_Ctags_Cmd='C:\Progra~1\Ctags\ctags.exe' +< + If you are using a cygwin compiled version of exuberant ctags on MS-Windows, + make sure that either you have the cygwin compiled sort utility installed + and available in your PATH or compile exuberant ctags with internal sort + support. Otherwise, when exuberant ctags sorts the tags output by invoking + the sort utility, it may end up invoking the MS-Windows version of + sort.exe, thereby resulting in failure. + +Q. When I try to open the taglist window, I am seeing the following error + message. How do I fix this problem? + + Taglist: Failed to generate tags for /my/path/to/file + ctags: illegal option -- -^@usage: ctags [-BFadtuwvx] [-f tagsfile] file ... + +A. The taglist plugin will work only with the exuberant ctags tool. You + cannot use the GNU ctags or the Unix ctags program with the taglist plugin. + You will see an error message similar to the one shown above, if you try + use a non-exuberant ctags program with Vim. To fix this problem, either add + the exuberant ctags tool location to the PATH environment variable or set + the 'Tlist_Ctags_Cmd' variable. + +Q. A file has more than one tag with the same name. When I select a tag name + from the taglist window, the cursor is positioned at the incorrect tag + location. +A. The taglist plugin uses the search pattern generated by the exuberant ctags + utility to position the cursor at the location of a tag definition. If a + file has more than one tag with the same name and same prototype, then the + search pattern will be the same. In this case, when searching for the tag + pattern, the cursor may be positioned at the incorrect location. + +Q. I have made some modifications to my file and introduced new + functions/classes/variables. I have not yet saved my file. The taglist + plugin is not displaying the new tags when I update the taglist window. +A. The exuberant ctags utility will process only files that are present in the + disk. To list the tags defined in a file, you have to save the file and + then update the taglist window. + +Q. I have created a ctags file using the exuberant ctags utility for my source + tree. How do I configure the taglist plugin to use this tags file? +A. The taglist plugin doesn't use a tags file stored in disk. For every opened + file, the taglist plugin invokes the exuberant ctags utility to get the + list of tags dynamically. The Vim system() function is used to invoke + exuberant ctags and get the ctags output. This function internally uses a + temporary file to store the output. This file is deleted after the output + from the command is read. So you will never see the file that contains the + output of exuberant ctags. + +Q. When I set the |'updatetime'| option to a low value (less than 1000) and if + I keep pressing a key with the taglist window open, the current buffer + contents are changed. Why is this? +A. The taglist plugin uses the |CursorHold| autocmd to highlight the current + tag. The CursorHold autocmd triggers for every |'updatetime'| milliseconds. + If the |'updatetime'| option is set to a low value, then the CursorHold + autocmd will be triggered frequently. As the taglist plugin changes + the focus to the taglist window to highlight the current tag, this could + interfere with the key movement resulting in changing the contents of + the current buffer. The workaround for this problem is to not set the + |'updatetime'| option to a low value. + +============================================================================== + *taglist-license* +11.
