Improve section about Doxygen configuration

Doxygen Plugin for Trac


Integrates doxygen documentation into Trac.

The aim is to embed one or multiple doxygen-generated documentation(s) within Trac, in order to have consistent look and feel, and easy referencing to doxygen pages using the usual TracLinks and the doxygen: prefix.

The doxygen plugin 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, main.html (default) or hierarchy.html. 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 should be easy if you have only one Doxygen generated documentation to wrap, and a bit more involved if you have many --but the goal is to have a great deal of flexibility, in the latter case.

You can check out the source for DoxygenPlugin from Subversion at, or browse the source locally. See log:/doxygenplugin for recent changes.



Download the source code for the DoxygenPlugin from [download:doxygenplugin here] or checkout the source from the trac hacks subversion repository at:

Change to the doxygenplugin/0.9 directory and run:

python 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 outlined below.

Configuring Trac

Basic Configuration

A [doxygen] section should be created in TracIni. There's only one mandatory setting, it's the path to the generated documentation. This should match the OUTPUT_DIRECTORY setting in the Doxyfile.

Settings for Multiple Documentation Projects

In this case, the path option is used to set a common prefix, shared by all the generated documentations. You can also use default_documentation to specify which project should be used when no explicit path are given when requesting a documentation file, when using the doxygen: TracLinks.

Let's imagine you have two sets of documentation, one for the latest trunk, one for a stable branch, and they are generated at the following locations:

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

You want to have links like doxygen:MyClass refer to the documentation for the stable branch, i.e. to be equivalent to doxygen:stable/MyClass.

path = /var/cache/doxygen
default_documentation = stable
wiki_index = DoxyGen

It is advised to used the wiki_index in this situation, so you can place links to both documentation sets:

= Documentation generated by Doxygen =

 - Documentation for the stable API: 
   [doxygen:stable/hierarchy class hierarchy], [doxygen:stable/dirs directory hierarchy]
 - Documentation for the trunk API: 
   [doxygen:devel/hierarchy class hierarchy], [doxygen:devel/dirs directory hierarchy]

Options Summary

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

Option Name Documentation Default value
path Directory containing doxygen generated files.
title Title to use for the main navigation tab. Doxygen
ext Space separated list of extensions for doxygen managed files. htm html png
source_ext Space separated list of source files extensions idl odl java cs py php php4 inc phtml m cpp cxx c hpp hxx h
default_documentation Default documentation project, relative to [doxygen] path. When no explicit path is given in a documentation request, this path will be prepended to the request before looking for documentation files.
index Default index page to pick in the generated documentation. main.html
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. iso-8859-1

(the above is in sync with r1245

If you want to change main navigation menu button label put this to ![doxygen] section in trac.ini:

title = Documentation

If you install the plugin globally, you'll also need to enable it in trac.ini as follows:

doxygentrac.* = enabled

Configuring Doxygen

The only configuration setting in the Doxyfile that is required to make this plugin work is GENERATE_HTML.

Since this plugin just embeds the html pages generated by doxygen you will need to define a custom header and footer even if it will be containing only blank line.

HTML_HEADER            = TracHeader.html
HTML_FOOTER            = TracFooter.html


These files must contain something, a blank line is sufficient, or doxygen will put in the defaults. You can put there you own CSS style as in following example:

<style type="text/css">
        h1 { text-align: center; }

and my TracFooter.html contains a blank line.

To enable the search option, the SEARCHENGINE setting must be set to YES (of course, calls to the php search script will be hijacked by this plugin, so you don't need to bother to install/configure php ;) ).

Wiki Macros

Using provided wiki macro you can make a link to doxygen documentation page wherever you want. Specified links are related to setted up doxygen path:

[doxygen:main.html Documentation] # Simple documentation in doxygen path.
[doxygen:FirstProject/main.html First]   # Multiple documentation in separate
[doxygen:SecondProject/main.html Second] # directories in doxygen path.
