Overview The "Tag Explorer" plugin provides the following features: 1. Opens a vertically/horizontally split Vim window with a list of files in    a directory. You can list all the tags (functions, classes, structures,    variables, etc) defined in a file. You can jump to the location where a    tag is defined. You can edit a selected file. You can browse through the    directories. 2. Groups the tags by their type and displays them in a foldable tree. 3. When a tag name is selected from the explorer window, positions the cursor    at the definition of the tag in the source file 4. Can display the prototype of a tag from the tag explorer window. 5. Displays the scope of a tag. 6. The displayed tags can be sorted either by name or by line number. 7. Supports the following programming language files: Assembly, ASP, Awk, C,    C++, Cobol, Eiffel, Fortran, Java, Lisp, Make, Pascal, Perl, PHP, Python,    Rexx, Ruby, Scheme, Shell, Slang, Sql, TCL, Verilog, Vim and Yacc. 8. Runs in all the platforms where the exuberant ctags utility and Vim are    supported (this includes MS-Windows and Unix based systems). 9. Runs in both console/terminal and GUI versions of Vim. This plugin relies on the exuberant ctags utility to generate the tag listing. You can download the exuberant ctags utility from http://ctags.sourceforge.net. The exuberant ctags utility must be installed in your system to use this plugin. Exuberant ctags version 5.3 and above is recommended.  There is no need for you to create a tags file to use this plugin. Installation 1. Copy the tagexplorer.vim script to the $HOME/.vim/plugin directory.    Refer to ':help add-plugin', ':help add-global-plugin' and ':help    runtimepath' for more details about Vim plugins. 2. Set the TE_Ctags_Path variable to point to the exuberant ctags utility    path. 3. If you are running a terminal/console version of Vim and the terminal    doesn't support changing the window width then set the TE_Adjust_Winwidth    variable to 0. 4. Restart Vim. 5. You can use the ":TagExplorer" command to open/close the tag explorer    window. Usage You can open the tag explorer window using the ":TagExplorer" command. Invoking this command will toggle (open or close) the tag explorer window. You can map a key to invoke this command:               nnoremap <silent> <F8> :TagExplorer<CR> Add the above mapping to your ~/.vimrc file. You can close the tag explorer window from the tag explorer window by pressing 'q' or using the Vim ":q" or using one of the Vim window CTRL-W commands. When the tag explorer window is opened, the names of all the directories and files in the current directory will be displayed. When a directory name is selected by pressing the <Enter> key or by double clicking with the mouse, the contents of the selected directory will be displayed. You can go to the parent directory by selecting the ".." entry. When a file name is selected by pressing the <Enter> key or by double clicking with the mouse, the selected file will be opened in a window. You can display all the tags (variable, function, class, etc) defined in a file using the 'o' command.  The tag names will grouped by their type (variable, function, class, etc) and displayed as a foldable tree using the Vim folding support. You can collapse the tree using the 'c' command. You can open the tree using the 'o' command.  You can also use the mouse to open/close the folds. You can use the '+' and '-' keys to open and close the folds for a tag type. You can select a tag either by pressing the <Enter> key or by double clicking the tag name using the mouse. For tags with scope information (like class members, structures inside structures, etc), the scope information will be displayed in square brackets "[]" after the tagname. By default, the tag list will be sorted by the order in which the tags appear in the file. You can sort the tags either by name or by order by pressing the "s" key in the tag explorer window. You can display the prototype of a tag by pressing <Spacebar> key when the cursor is placed over a tag name. You can update the tags listed for a file by pressing the 'u' key in the tag explorer window. You can open a different directory by using the 'g' command. You will be prompted to enter the name of the directory. You can recall the previously entered directory names by pressing the Up and Down arrow keys. The last displayed directory name will be the first available name in the history. To get help on the keys, press the "?" key in the tag explorer window. This script relies on the Vim "filetype" detection mechanism to determine the type of the current file. To turn on filetype detection use               :filetype on This script will not work in 'compatible' mode.  Make sure the 'compatible' option is not set. Configuration By changing the following variables you can configure the behavior of this plugin. Set the following variables in your .vimrc file using the 'let' command. The plugin uses the TE_Ctags_Path variable to locate the ctags utility.  By default, this is set to ctags. Set this variable to point to the location of the ctags utility in your system:               let TE_Ctags_Path = 'd:\tools\ctags.exe' By default, the tag names will be listed in the order in which they are defined in the file. You can alphabetically sort the tag names by pressing the "s" key in the tag explorer window. You can also change the default order by setting the variable TE_Sort_Type to "name" or "order":               let TE_Sort_Type = "name" By default, all the file names in a directory will be displayed in the explorer window. If you want to display only selective filenames, you can set the 'TE_Include_File_Pattern' variable. If this variable is set to empty string, all the files in the directory will be displayed. You have to set this variable to a Vim regular expression pattern value. For example, to display only .c and .h files, set this variable to               let TE_Include_File_Pattern = '.*\.c$\|.*\.h$' You can set the 'TE_Exclude_File_Pattern' variable to skip file names matching a Vim regular expression pattern. For example, to skip the .o, .obj .bak, core and tags files, set this variable to               let TE_Exclude_File_Pattern = '.*\.o$\|.*\.obj$\|.*\.bak$' .                                             '\|.*\.swp$\|core\|tags' By default, all the sub-directory names in a directory will be displayed in the explorer window. If you want to display only selective directories, you can set the 'TE_Include_Dir_Pattern' variable. If this variable is set to empty string, all the sub-directories in the directory will be displayed. You have to set this variable to a Vim regular expression pattern value. For example, to include only those directories containing vim or unix in the name, use               let TE_Include_Dir_Pattern = '.*vim.*\|.*unix.*' You can set the 'TE_Exclude_Dir_Pattern' variable to skip directories matching a Vim regular expression pattern. By default, this variable is set to empty. For example, to exclude all the directories starting with obj or containing test, use               let TE_Exclude_Dir_Pattern = 'obj.*\|.*test.*' Be default, the tag names will be listed in a vertically split window.  If you prefer a horizontally split window, then set the 'TE_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 TE_Use_Horiz_Window = 1 By default, the vertically split tag explorer window will appear on the left hand side. If you prefer to open the window on the right hand side, you can set the TE_Use_Right_Window variable to one:               let TE_Use_Right_Window = 1 You can also open the tag explorer window on startup using the following command line:               $ vim +TagExplorer The default width of the vertically split tag explorer window will be 30. This can be changed by modifying the TE_WinWidth variable:               let TE_WinWidth = 20 Note that the value of the 'winwidth' option setting determines the minimum width of the current window. If you set the 'TE_WinWidth' variable to a value less than that of the 'winwidth' option setting, then Vim will use the value of the 'winwidth' option. By default, when the width of the window is less than 100 and a new tag explorer window is opened vertically, then the window width will be increased by the value set in the TE_WinWidth variable to accomodate the new window.  The value of this variable is used only if you are using a vertically split tag explorer 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 'TE_Adjust_Winwidth' variable to 0.  CAUTION: If you are using the MS-Windows version of Vim in a MS-DOS command window then you must set this variable to 0, otherwise the system may hang due to a Vim limitation (explained in :help win32-problems)               let TE_Adjust_Winwidth = 0
