Doxygen extensions

Since the number of tools/scripts is ever growing, I've divided them into a number of categories:

Diagram generators

Nassi-Shneiderman diagrams

Eckard Klotz has started a projected called Moritz. It generates Nassi-Shneiderman diagrams of functions and methods in C/C++ sources as HTML files, which could be included in software documentation or simply viewed in a web browser.

Filters to add support for other languages


Bret Jordan has written a filter Another filter is written by Thomas Aeby.


For those working with JavaScript it may be good to know that Jörg Schaible has written a perl script to let doxygen deal with it. Unfortunately his site at has been removed. If you google for you can still find copies of the script however.

Object Pascal

Darren Bowles has started a project Pas2dox which converts Object Pascal into a C++ style syntax, that doxygen can then happily parse. The project's goal is to allow doxygen to be used for Delphi/Kylix projects.

Visual Basic

Mathias Henze wrote an awk script that converts Visual Basic code into something doxygen understands. The package includes a small batch-wrapper. To use it, one has to put following line for the config-option "INPUT_FILTER":

C:/path/to/filer/tools/vbfilter.bat C:\path\to\filter\tools

Some Unix tools like sh.exe, gawk.exe and tee.exe are required to be available under the supplied path. They can be downloaded here.

An alternative filter for Visual Basic is provided by Basti Grembowietz. It requires python and comes with the following usage instructions:

The VB-Files have to be prepared the following way:

  '* <comments directly handed to doxygen>
  <vb- Function / Sub / Member>

For shorter usage also this is allowed:

  <vb-member (recommended)> '* <doxygen-comment>

For comments addressing to a class / module, '! must be used.

Giovanni De Cicco wrote an Add-in called VBDoxyAddin for VB6 developers based on the script of Mathias.

For the newer VB.NET (and also for classic VB) an awk based filter was written by Vsevolod Kukol.


Ben Heasly has written a filter for doxygen that converts MatLab scripts (including the new object oriented features) into something doxygen can understand.

An alternative filter is provided by Ian Martins.

There is also one by Fabrice which can be found on Matlab Central.


Darren Bowles has created Proc2Dox, which is a pre-processor addon for doxygen to add support for Pro*C code.


Bogdan Drozdowski and Rick Foos have written a filter to convert assembly into C like code which doxygen can then parse.


Alec Chen has written a filter to make doxygen parse Lua code. Simon Dales has another lua filter to do the same.

GLSL Shader

Sebastian Schaefer has a written a filter to make doxygen parser the GLSL shader language.


Aurélien Gâteau has written a filter for Qt's QML files.


The GOB-doc filter parses *.gob files and produces C++ class definitions.


Dr Beco wrote a filter for Prolog.


Bretislav Rychta wrote filter for CAPL the CAN Access Programming Language.


Jan Lochmatter has written a filter for the STX language, which is used for PLC's (programmable logic controller) from the german manufacturer Jetter.


Raffaele Intorcia wrote a Python script that provides a simple conversion from KickAssembler source code into C-like format.

Increase ease of use


Pierre Clouthier wrote Doxygenator which is a tool to automatically insert Doxygen comment blocks before functions. The Doxygen commands are a template or skeleton, you fill in the details.


ChEeTaH wrote DoxyAssist. This tool can use a template doxygen configuration file and adjust its settings for specific projects and sub projects it manages. For each (sub) project doxygen is run separately, resulting in separate documentation sets for each sub project. It will combine these parts back for the Qt Assistant, making sure the appropriate filters are available. Qt Assistant can then be used to view the documentation as a whole, or easily limit the view to a subproject. There is special support for Drupal, for which all contributed modules are automatically discovered and added as subproject (see this demonstration).


Eclox is a doxygen frontend plugin for Eclipse.

Visual studio

If you use Visual Studio .NET have a look at Steve King's set of addins. Greg Engelstad has written a perl script to parse a Visual Studio .NET solution file (.sln) and run doxygen for each separate project contained therein.

Jason Williams has written an Addin for Visual Studio 2005 & 2008 which is able to auto-generate doxygen (or DocXml) style comments from most code elements (file, namespace, class, struct, enum, function, etc). It parses C, C++, C# and Java code to produce fully formed doxygen comments, and can update those comments if the code element is changed, and word-wrap the descriptions to keep them tidy. It uses a set of user-editable rules to provide automatic descriptions of elements, parameters and return codes, minimizing the effort involved in generating doc comments.

jgallardo has also written a Addin for Visual Studio that eases browsing the documentation generated by doxygen.

An addin for Visual Studio 2005 called DoxyComment was created by Troels Gram. It is designed to assist you in inserting context sensitive comment blocks into C/C++ source files. DoxyComment also comes with an xslt template that lets you generate documentation like the MSDN library.

If you are using Microsoft's Developer Studio 6.0, an add-in called DoxBar is available that can be used to run doxygen from within Developer Studio and to search through the generated HTML help files.
Note: I do not have enough time to maintain DoxBar myself anymore, so I moved DoxBar to sourceforge. Olivier Sannier has introduced a number of improvements to DoxBar. If you too want to join the development team, please register as a user at sourceforge and mail me your user name.

Bernhard Nowara has written a profile editor, which is a doxywizard-like tool for Windows. He also created an enhanced version of DoxBar that includes his editor and some macros for Visual Studio to ease the preparation of the source code for doxygen. These changed have been merged into more recent version of doxygen by Olivier Sannier.

FeinSoftware has released a development tool for Microsoft Visual Studio .NET (Visual C++) called CommentMaker, which creates customizable function header that developers can adjust to most specific documentation requirements. By default it generates doxygen compatible comments.

TechPubs Tools

Glenn Maxey has released The TechPubs Tools (TPT) which wraps around any number of mini-HTML systems and creates a comprehensive HTML system complete with table of contents and an auto-generated index/concordance. TPT consists of Perl programs, UNIX shell scripts, and master template files (HTML).

Tree view applet

Those having performance problems with the TREEVIEW option, could try this script written by Glenn Maxey.

MSDN integration

For those using Windows and wanting to integrate the compressed HTML generated by doxygen into MSDN look at this MSDN integrator utility.

Configure via Perl

Richard Y. Kim has written a perl module to use/configure doxygen more easily from perl scripts.

Ant task

If you're into Ant have a look at Karthik A Kumar's Ant task object's for doxygen.

Automake/autoconf integration

Oren Ben-Kiki shows how to integrate doxygen with Automake and Autoconf.

Embed HTML

Wilfred Nilsen has written a tool (for windows) to combine multiple HTML files and embed them in a single executable. This could be used in combination with the doxygen's HTML output.

Trac plugin

If you are using Trac to track your issue then have a look at this plugin to embed doxygen documentation.

CMake integration

Stefan Majewsky has written a blog entry about integrating doxygen in a CMake based project.


Raja Kajiev write a tool called DoxyGrouper which can help to include items into groups on directory structure basis.


Markus Schwartz wrote a tool called qtres2dox which can generate an input file for doxygen from .ui and .qrc files.


Doxynum is a program for automatic numbering of sections and drawings, as well as for creating contents in documentation, generated using the doxygen software

Editor addons

Visual Studio

Sedeniono wrote VSDoxyHighlighter, a Visual Studio 2022 extension to provide syntax highlighting and autocomplete functionality.

Christoph Schlosser wrote VS Code Extensions provides Doxygen Documentation generation on the fly by starting a Doxygen comment block and pressing enter. which is a VS Code Extensions that provides Doxygen Documentation generation on the fly by starting a Doxygen comment block and pressing enter.


If VIM is your favorite editor (it is mine!), Michael Geddes wrote a syntax highlighting script on top of C/C++/IDL/Java. Ralf Schandl also has a some macros and syntax highlighting files for you. Emilio Riva sent yet an alternative vim highlighting file.


If you are using the Emacs editor, take a look at epydoc-el which is a lisp script to simplify writing doxygen comments.

Ryan Sammartino maintains a project called Doxymacs at sourceforge, which produced an elisp package to make using doxygen from within {X}Emacs easier.


If UltraEdit is your editor of choice, take a look at Dominik Stadler's script for information on how to enable syntax highlighting for doxygen comment blocks.

TSE Pro/32

For SemWare's TSE Pro/32 editor Howard Kapustein has provided syntax definition files for doxygen style comment blocks.

Delphi/C++ Builder

If you use Delphi or C++ Builder in combination with GExperts you can use this XML macro written by Miguel A. Richard to serve as a template for comments in your code.

Migration from other doc tools


If you want to convert Cocoon (or C++) style comments into Qt-style comments on the fly you might want to try the script written by Paul S. Strauss. Use it in combination with doxygen's INPUT_FILTER configuration option.


Martin Slater wrote a python script duck2dox that can be used to convert AutoDuck style comments to doxygen comments. Steven Blackburn has written an alternative filter written in C++. Brian Szuter has written yet another filter after trying the other filters and finding them inadequate for his needs.

XML/XSLT examples


Micheal Jones has written an extension to reStructuredText and Sphinx to be able to read and render the doxygen XML output.

C# doxmlparser

Baneu Mihai has written a wrapper around doxygen's xml parser (found in addon/doxmlparser) to make it accessible from C#.


Matt Ball has written a script called doxyclean to convert doxygen's output into something that closer resembles Apple's own documentation.


Thomas Hansen and Kariem Ali have written Doxygen.NET which provides .NET object wrappers for the XML output generated by doxygen.


Narech Koumar has written a tool called Dox which reads the XML output produced by doxygen and turns that into formatted HTML whose style resembles that of Javadoc's.

XSLT examples

If you want to see how you can use XSLT to transform doxygen's XML output into something else (HTML/CHM in this case), have a look at Chelpanov's example. It has some limitations though:

  • C++ is not supported
  • It is slower than using doxygen directly or writing a SAX based transformation in C from XML to HTML.
  • It support the CHM format only.
  • It works on Windows platform only.
  • Only some of the features of doxygen are supported.

and some additional requirements:

  • HTML Help WorkShop
  • Microsoft .Net Framework 1.1

If you have comments or suggestions please send them to Chelpanov (remove the the NO_SPAM part from the mail address).

Bo Peng wrote a small XSLT script to extract information for SWIG/Python interfaces.
