add-local-help| * @htmlonly * @endhtmlonly Doxygen is a documentation system for C++, C, Java, Objective-C, IDL and to some extent PHP, C#, and D (http://www.stack.nl/~dimitri/doxygen/index.html, and Doxygen manual). Doxygen allows a variety of styles for special documentation blocks. There is also a great number of Doxygen commands which can be combined freely into comment blocks. For that reason it makes no sense to code these possibilities directly into a plugin. Therefor this plugin let you define a file with templates for Doxygen documentation blocks. This file will be read when Vim starts or by an explicit rebuild command. The template file will then be analyzed and a menu item will be created on the fly for each template found (gVim). In parallel an Ex command will be generated for each item. For the console version Vim only the Ex commands are available.
1. THE TEMPLATE FILE doxygensupport-template-file
This plugin comes with template files. These files are examples or suggestions to allow you a quickstart. Please read more to learn how to write your own templates. The main template file (default is $HOME/.vim/plugin/doxygen.templates) can have three sorts of entries.
1.1 Template file comments doxygensupport-template-comments
Lines starting with a '#' are comments. If a line in a template body starts with a '#' (e.g. a C preprocessor statement) this character has to be escaped (|doxygensupport-doxygen-templates|).
1.2 Template file macros doxygensupport-template-macros
Macros are optional. The syntax is $
<macroname>starts with a letter followed by optional letters, digits or underscores. A
<macroexpansion>is the text on the right of the equal sign, starting with the first non-whitespace character after the equal sign and ending with the last non-whitespace in this line. An example $AUTHOR$ "Dr. Fritz Mehner" There are a few predefined macro names: $AUTHOR$ $AUTHORREF$ $EMAIL$ $COMPANY$ $PROJECT$ $COPYRIGHTHOLDER$ An
<macroexpansion>may contain other macros to be expanded. The recursion is limited by the expansion algorithm to a depth of 10. The order of the macro definitions does not matter. Macro names are case sensitive. There are a few other predefined macros with fixed meaning (but see also |doxygentemplates-date| for date and time representation): $DATE$ The preferred date representation for the current locale without the time. $YEAR$ The year as a decimal number including the century. $TIME$ The preferred time representation for the current locale without the date and the time zone or name or abbreviation. $FILE$ The filename without the path. $PATH$ The pathname without filename. $BASENAME$ Filename without path and suffix. $SUFFIX$ The filename extension. $sortmenus$ Sorted menus yes/no (see below) $includefile$ Include a template file (see below). REMARKS. Case of letters matters. Do not name a macro 'Id' if you want this to be expanded by a revision control system.
<CURSOR>The cursor position after insertion of a template
<SPLIT>The split point when inserting in visual mode (see|doxygensupport-doxygen-templates|) A dependent template file can start with its own macro section. There is no need to have all user defined macros in the master file. When the first template definition is found (see below) macro definitions are no longer recognized.
1.3 Predefined Control Macros doxygensupport-control-macros
The menu items can be sorted with the macro $sortmenus$ = yes Default is 'no'. This plugin has an include mechanism. The templates can be split in different files. These can be included, e.g. $includefile$ = doxygen.cpp.templates $includefile$ = doxygen.java.templates Each file will be included only once. The file names may not have a path. The path is assumed to be the same as for the main templates file (see |doxygensupport-template-file|).
1.4 Doxygen Templates doxygensupport-doxygen-templates
A template definition has the following form: ==
<insert mode>==][comment] 1. template line 2. template line ... It starts with a headline with the syntax shown above followed by a Doxygen comment. The insert mode part (see below) and the comment part are optional. Whitespaces between the parts are allowed. The end of a definition is the start of a new template definition or the end of the file. A
<templatename>starts with a letter followed by optional letters, digits, or allowed delimiters. The allowed delimiters are ' ' blank '-' minus '+' plus '_' underscore ',' comma '.' point A template can contain empty lines. The number of templates is not limited. Here an example template enclosed in delimiting comments: #-------------------------------------------------------------- ==brief+detailed== /** * \brief
<CURSOR>* * Detailed description starts here. */ #--------------------------------------------------------------
INSERT MODE SPECIFICATION
There are 4 insert modes: 'above', 'append', 'below', 'insert', and 'start'. The default is 'below' The insert mode specification is optional. A wrong specification will be replaced by the default. above insert the template before the current line append append the template to the current line below insert the template below the current line insert insert the template at the cursor position start insert the template before the first line of the buffer Examples: #-------------------------------------------------------------- ==brief-after-member==append== /*< \brief <CURSOR> / #-------------------------------------------------------------- #-------------------------------------------------------------- == brief,detailed == /** * @brief
<CURSOR>* * Detailed description starts here. */ #-------------------------------------------------------------- INSERT. In-text formulas should be put between a pair of @f$ commands. The following template will be inserted in the running text. The cursor will be set inside the construct. #-------------------------------------------------------------- == formula-in-text == insert == @f$
<CURSOR>@f$ #-------------------------------------------------------------- All templates can have more than one line. Templates for the visual mode can use
<SPLIT>. The text before
<SPLIT>will than be inserted above/before the marked area, the text after
<SPLIT>will be inserted below/behind the marked area. An example: #-------------------------------------------------------------- == formula-in-text == insert == @f$
<SPLIT>@f$ #-------------------------------------------------------------- Templates not containing
<SPLIT>do not have a visual mode.
If the usage of a yet undefined user macro starts with a question mark the user will be asked for the replacement first, e.g. with the following template == Cpp.class == /// /// @class $?CLASSNAME$ /// @brief
<CURSOR>/// /// Description of class $CLASSNAME$ starts here. /// The user can specify the function name which then will be applied twice. If the macro was already in use the old value will be suggested as default.
A macro expansion can be controlled by the following attributes :l change macro text to lowercase :u change macro text to uppercase :c capitalize macro text :L legalize name Legalization means: - replace all whitespaces by underscores - replace all non-word characters by underscores - replace '+' and '-' by underscore EXAMPLE. To ask for a class name and to make sure that it will start with an uppercase letter write == Cpp.class == /// /// @class $?CLASSNAME:c$ /// @brief
HINT. According to the syntax of the headline the 'append' followed by '==' in the line ==brief-after-member==append== is an insert mode specification. The 'append' in ==brief-after-member==append is a comment. The insert mode is now 'below'.
2. THE DOXYGEN MENU doxygensupport-menu
The Doxygen menu will be generated when the editor starts (GUI only) or on demand (see|doxygensupport-rebuild|). The template names from the template definition file become menu items linked with the template body. The template body will be inserted below the cursor. The delimiter '.' has a special meaning: it separates a submenu name from its submenu items. The template names ==block.short== ==block.long== ==block.special== will generate a submenu entry 'block' with the items 'short', 'long', and 'special' : block --+--> long | +--> short | +--> special This feature can be used to arrange the templates into groups. The template names ==C.block-short== ==C.block-long== ==C.block-special== ==Cpp.block-short== ==Cpp.block-long== ==Cpp.block-special== result in menus in which the templates are arranged according to C/C++ commenting styles: C --+--> block-short +--> block-long +--> block-special Cpp --+--> block-short +--> block-long +--> block-special The first group will be reached by Ex commands beginning with 'DoxyC' the second group by 'DoxyCpp' (see below).
3. THE DOXYGEN EX COMMANDS doxygensupport-ex-commands
This plugin generates an Ex command for each Doxygen template. These commands will be generated when the editor starts or on demand (see|doxygensupport-rebuild|). Vim Ex command names have to start always with an uppercase letter followed by letters or digits. Delimiters are not allowed. The user defined template names are therefore transformed into camel case notation. The parts separated by the delimiters are joined together now. The first letter of each part will be transformed to uppercase. The new word will be prefixed by 'Doxy'. Some examples: template name Ex command
==block.long== DoxyBlockLong ==block.short== DoxyBlockShort ==block.special== DoxyBlockSpecial ==file-header== DoxyFileHeader ==function== DoxyFunction *** You do not need to remember the names of these Ex commands. Just type *** 'Doxy' on the command line and use the tab expansion to show the names *** and to choose from. NAMING CONFLICTS. The template names ==block-special== DoxyBlockSpecial ==block+special== DoxyBlockSpecial will generate two different menu items but obviously the same Ex command name. Avoiding these conflicts is up to you. The Ex command leader can be changed (see|doxygensupport-customization|).
4. REBUILD MENUS AND EX COMMANDS doxygensupport-rebuild
Rebuilding the menu(s) and the Ex commands is necessary after changing the template file. Local template files: see |doxygensupport-template-file| Global template files: see |doxygensupport-system-wide| GUI (gVim or Vim in an xterm)
Edit the template file. Choosing the first menu item will reread the template files and rebuild the menu and the Ex commands. Console (Vim)
Using the command ':Doxygen' will reread the template files and rebuild the Ex commands.
5. THE RUN MENU doxygensupport-run
The run menu let you generate the doxygen documentation. Doxygen has a lot of options. This plugin needs a doxygen config file. The best way to use it is probably to generate a doxygen config file in the directory containing the sources you want to document (see|doxygensupport-configfile|) and to adapt it to your needs. 5.1 Menu entry 'run doxygen' If no other information is given (working directory, config file) doxygen will try to build a documentation in the current directory. If a config file with the default name 'Doxyfile' is present it will be used otherwise you will be asked for a config file. 5.2 Menu entry 'select working directory' doxygensupport-working-dir Select the directory in which to run doxygen. This is convenient if you are working in a subdirectory at the moment. The entry 'plugin settings' shows the currently selected directory. 5.3 Menu entry 'select config file' doxygensupport-select-config-file Select a config file if you use one with a non-standard name. The working directory will be set to the directory containing this config file. 5.4 Menu entry 'edit config file' doxygensupport-edit-config-file Edit the selected config file. start a file browser if file 'Doxyfile' is not present or no other config file was specified. 5.5 Menu entry 'generate a config file' doxygensupport-configfile The menu entry 'generate a config file' starts a file browser and suggests the default config file name 'Doxyfile'. The config file can have any name. The file with the given name will then be generated by doxygen. The config files are well documented but you may want to read the doxygen documentation too. 5.6 Menu entry 'edit local templates' doxygensupport-local-templates The menu item 'edit local templates' opens a file browser for the directory containing the template files of a local plugin installation. This is usually '~/.vim/doxygen-support/templates/'. Now change whatever file you want, save it, and click on the run menu item 'reread templates' to read in the file(s) and to rebuild the internal representation of the templates. 5.7 Menu entry 'edit global templates' doxygensupport-global-templates The menu item 'edit global templates' opens a file browser for the directory containing the template files of a global plugin installation. This is usually '$VIM./vimfiles/doxygen-support/templates/'. Now change whatever file you want, save it, and click on the run menu item 'reread templates' to read in the file(s) and to rebuild the internal representation of the templates. 5.8 Menu entry 'reread templates' doxygensupport-reread-templates Read the template files (after a change or addition) and build a new inner representation of the templates. 5.9 Menu entry 'plugin settings' doxygensupport-settings This menu entry shows the actual settings for the plugin. Some of them can change during a session (e.g. current the current working directory). 5.10 Run ex commands doxygensupport-run-ex-commands To allow the usage of the functions of the run menu within Vim (without GUI) the following ex commands are available: DxRun DxSelectWorkingDir DxSelectConfigFile DxEditConfigFile DxGenerateConfigFile DxEditLocalTemplates DxEditGlobalTemplates DxReread DxSettings These commands start with 'Dx' to separate the names from the commands generated for the templates. Start with ':Dx' on the Vim commandline and use tab completion to avoid typing (and remembering the command name).
6. CUSTOMIZATION doxygensupport-customization
Several global variables are checked by the script to customize it:
global variable default value
let g:Doxy_ExCommandLeader 'Doxy' let g:Doxy_LoadMenus 'yes' let g:Doxy_RootMenu 'Do&xy.' let g:Doxy_TemplateOverwrittenMsg 'no' The variable g:Doxy_ExCommandLeader can be used to change the default name of the Ex command leader (see|doxygensupport-ex-commands|). The string must start with an uppercase letter and can contain only letters and digits. Everything else will be removed. The variable g:Doxy_LoadMenus controls if the Vim root menu item 'Doxy' will appear after start. When set to 'no' the menu item can be made visible from the 'tool' menu. The variable g:Doxy_RootMenu, if set (in .vimrc or in .gvimrc), gives the name of the single gVim root menu entry. The default is 'Do&xy.' .
Notethe terminating dot. An empty string is not allowed. The next character after & is the shortcut key for this menu. If you want to set the plugin menu into another menu, e.g. 'Plugin', this is done by the following line in '.vimrc' let g:Doxy_RootMenu = "&Plugin.Do&xy." If the variable g:Doxy_TemplateOverwrittenMsg is set to 'yes' all templates overwriten by a rebuild will be reported. There are more global variables for special purposes: - see |doxygensupport-system-wide| - see |doxygentemplates-date|
USER DEFINED FORMATS FOR DATE AND TIME doxygentemplates-date
The format for $DATE$ ,$TIME$ , and$YEAR$ can be set by the user. The defaults are $DATE$ '%x' $TIME$ '%X' $YEAR$ '%Y' See the manual page of the C function strftime() for the format. The accepted format depends on your system, thus this is not portable! The maximum length of the result is 80 characters. User defined formats can be set using the following global variables in ~/.vimrc , e.g. let g:Doxy_FormatDate = '%D' let g:Doxy_FormatTime = '%H:%M' let g:Doxy_FormatYear = 'year %Y'
7. System-wide installation doxygensupport-system-wide
A system-wide installation (one installation for all users) is done as follows. As *** SUPERUSER *** : (1) Find the Vim installation directory. The Vim Ex command ':echo $VIM' gives '/usr/local/share/vim' or something like that. Beyond this directory you will find the Vim installation, e.g. in '/usr/local/share/vim/vim73' if Vim version 7.3 has been installed (Windows: 'C:\Program Files\Vim'). (2) Create a new subdirectory 'vimfiles', e.g. '/usr/local/share/vim/vimfiles' (Windows: 'C:\Program Files\Vim\vimfiles'). (3) Install Doxygen Support Copy the archive doxygen-support.zip to this new directory and unpack it: unzip doxygen-support.zip (4) Generate the help tags: :helptags $VIM/vimfiles/doc SPECIAL CASES. Some Linux distributions use non-standard names for Vim directories. SUSE has a directory '/usr/share/vim/site' to put plugins in. These directories will not be found automatically. After installing the plugin below '/usr/share/vim/site' the use of the templates will be enabled by the following line in '~/.vimrc': let g:Doxy_GlobalTemplateFile = '/usr/share/vim/site/doxygen-support/templates/doxygen.templates' As *** USER *** : Create your private snippet directory: mkdir --parents ~/.vim/doxygen-support/codesnippets You may want to copy the snippets coming with this plugin (in $VIM/vimfiles/doxygen-support/codesnippets) into the new directory or to set a link to the global directory. Create your private template directory: mkdir --parents ~/.vim/doxygen-support/templates Create a private template file 'doxygen.templates' (compulsory) in this directory to overwrite some macros, e.g. $AUTHOR$ = your name $AUTHORREF$ = ... $EMAIL$ = ... $COMPANY$ = ... $COPYRIGHT$ = ... You can also have local templates which overwrite the global ones. To suppress the messages in this case set a global variable in '~/.vimrc' (Windows: '~\_vimrc') : let g:Doxy_TemplateOverwrittenMsg= 'no' The default is 'yes'.
