wiki:DoxygenPlugin

Embed Doxygen-generated pages into Trac

Description

Doxygen logo

This plugin produces and embeds one or multiple Doxygen-generated documentation(s) within Trac, to have up-to-date documentation and easy referencing to Doxygen pages using the usual TracLinks and the doxygen: prefix. Doxygen itself is GPL licensed.

The plugin provides a new link in the admin panel, which will present a web form version of the Doxygen standard configuration file, named Doxyfile by default. Submitting the form will archive the chosen options, and Doxygen will run immediately on them.

The plugin also provides a new main navigation tab, named Doxygen by default, which will present an index page. If you have to present only one documentation project, that index page can directly be a Doxygen-generated page, like the index.html (default), files.html etc. An alternative is to pick a Wiki page to use as the index, and this is indeed the best option if you have multiple documentation projects to serve. That way you can build your own meta index the way you want, using doxygen:... links within that page.

Configuring the Doxygen plugin is straightforward if you have a Doxygen generated documentation ready and no other to use, and a bit more involved if you want to use all the features.

The trunk branch of this plugin is compatible with Trac >= 0.11 and Doxygen >= 1.8, and is the most recent version.

Note: the 0.10 branch of this plugin is deprecated and the 0.11 branch of this plugin is not maintained.

This documentation covers all versions.

Download

Download the zipped source for the trunk version.

Source

You can check out DoxygenPlugin from here using Subversion, or browse the source with Trac.

Installation

Install the plugin either manually or automatically. In either case, you may need to restart the web server to see the Doxygen button in the navigation menu bar.

Manual installation

Download the source code for the DoxygenPlugin from here or checkout the source from the Trac hacks subversion repository at https://trac-hacks.org/svn/doxygenplugin.

Change to the doxygenplugin/trunk (or another version) directory and run:

$ python setup.py bdist_egg

This will generate a Python egg in the dist directory. Copy the egg file into the trac/plugins directory and follow the Configuration steps below.

Scripted installation

Using easy_install to fetch, build and install:

$ sudo easy_install https://trac-hacks.org/svn/doxygenplugin/trunk/

Configuration

Basic Configuration

A [doxygen] section should be created in TracIni. There is only one mandatory setting, which is the path to the generated documentation. This should match the OUTPUT_DIRECTORY setting in the Doxyfile. If that is a relative path, you will need to prefix the current working directory used when running doxygen. Also, don't forget to grant the users the DOXYGEN_VIEW permission, else a blank page will be returned.

Note that there is also the HTML_OUTPUT setting which might play a role here. By default, the value for this setting is html, and this will be appended to the path specified in OUTPUT_DIRECTORY:

[doxygen]
path = /var/cache/doxygen/myproject

Settings for Multiple Documentation Projects

When documenting multiple projects, the path option is used to set a common prefix, which is shared by all generated documentations.

Suppose you are requesting a documentation file that has doxygen: TracLinks embedded. To specify which project should be used when no explicit path is given, you can also use default_documentation.

Example: Imagine you have two sets of documentation, one for the latest trunk and one for a stable branch, and they are like this:

$ cd /var/cache/doxygen
$ grep OUTPUT Doxyfile.stable
OUTPUT_DIRECTORY = stable
HTML_OUTPUT = html
$ grep OUTPUT Doxyfile.devel
OUTPUT_DIRECTORY = devel
HTML_OUTPUT = html
$ doxygen Doxyfile.stable
...
$ doxygen Doxyfile.devel
...

Now, you will have the following directory structure:

  • /var/cache/doxygen/stable/html
  • /var/cache/doxygen/devel/html

You want to have links like doxygen:MyClass refer to the documentation for the stable branch, ie to be equivalent to doxygen:stable/MyClass. To that end, you need the following setup:

[doxygen]
path = /var/cache/doxygen
default_documentation = stable
wiki_index = DoxyGen
html_output = html

In this situation use the wiki_index, so you can place links to both documentation sets:

= Documentation generated by Doxygen =

 - Main page for the stable documentation: 
   [doxygen:] or [doxygen:/] or [doxygen:stable/]
 - Documentation for the development documentation: 
   [doxygen:devel/]

Options Summary

These are all the configuration options recognized in the [doxygen] section of TracIni:

Option Name Documentation Default value
path Directory containing Doxygen ouput.
html_output Default documentation project suffix, as generated by Doxygen using the HTML_OUTPUT Doxygen configuration setting. (Since 0.10).
title Title to use for the main navigation tab. Doxygen
input Directory containing the sources. Mostly useful for Doxygen EXCLUDE option. (unavailable in versions <= 0.11)
doxyfile Full path of the Doxyfile to be created. (unavailable in versions <= 0.11)
doxygen Full path of the Doxygen command. (unavailable in versions <= 0.11) /usr/local/bin/doxygen
doxygen_args Argument of the Doxygen command. This is usefull if you plan to include the doxyfile produced by the plugin from another file to override a few Doxygen options (unavailable in versions <= 0.11) Default to the doxyfile option above.
searchdata_file The name of the file specified by the "SEARCHDATA_FILE" Doxygen configuration setting. (unavailable in versions <= 0.11) searchdata.xml
default_documentation Default documentation project, relative to [doxygen] path. When no explicit path is given in a documentation request, this path will be used to find the searchdata_file
index Default index page to pick in the generated documentation. index.html (main.html in versions <= 0.11)
wiki_index Wiki page to use as the default page for the Doxygen main page. If set, supersedes the [doxygen] index option.
encoding Default encoding used by the generated documentation files. (Since 0.10). utf-8 (iso-8859-1 in versions <= 0.11)
ext Space separated list of extensions for Doxygen managed files. (deprecated after version 0.11) htm html png
source_ext Space separated list of source files extensions. (deprecated after version 0.11) idl odl java cs py php php4 inc phtml m cpp cxx c hpp hxx h

(up to date with r15362)

If you install the plugin globally, you will also need to enable it in your trac.ini file:

[components]
doxygentrac.* = enabled

Configuring Doxygen

To make this plugin work, you have to set to YES the following items in the Doxyfile: GENERATE_HTML, SEARCHENGINE, SERVER_BASED_SEARCH and EXTERNAL_SEARCH. Note that calls to the search engine used by Doxygen will be hijacked by the Trac search engine.

You may replace the standard Doxygen header and footer HTML by your own files:

HTML_HEADER            = TracHeader.html
HTML_FOOTER            = TracFooter.html

See HTML_HEADER and HTML_FOOTER.

In versions <= 0.11, the CREATE_SUBDIRS option should be set to NO; this is not mandatory anymore.

It is possible to create links to Doxygen documentation from anywhere within a Wiki text, by using the doxygen: link prefix.

The general syntax of such links is: doxygen:documentation_path/documentation_target, where documentation_path is optional. If documentation_path is not specified, the [doxygen] default_documentation setting will be used instead.

The documentation_target part is used for specifying what Doxygen generated content will be displayed when following the link. It must be a name for which a documentation was produced by Doxygen, depending on the way you ran it. Most of the time, it will be a function, a class, a file etc. Technically, it must be the content of a field tag having a name attribute equals to name in the searchdata_file. If the name is empty, the link leads to the main page of the documentation; this is useful to give access to the main page of a documentation which is not the default one. For example the Wiki page of a project may list the documentations of the older versions with these links.

Some examples:

[doxygen:foo] # Link to the documentation of the function (or class etc) foo in the main documentation.
[doxygen:SecondProject/foo] similarly for another documentation.
[doxygen:] or [doxygen:/] Main page of the documentation.
[doxygen:SecondProject/] Main page of the second project documentation.
