File comments include details like licensing and copyright if any, author information, the purpose of the file, known bugs, change log etc. Documenting filesĪll files must have file comments. IMPORTANT - in your Doxyfile configuration ALWAYS set JAVADOC_BANNER = NO, such that Doxygen will interpret these boxed comments as comments and ignore them. * Software Foundation either version 3, or (at your option) any later * * the terms of the GNU General Public License as published by the Free * * GCC is free software you can redistribute it and/or modify it under * * Copyright (C) 1988-2021 Free Software Foundation, Inc. The templates use the Qt style - /*! as the preferred style for generating C/C++ documentation using Doxygen. Steve Oualline's classic book - C Elements of Style.The content of the templates has been inspired from multiple sources: This is a collection of templates to generate documentation for C source code using Doxygen. Step III - run doxygen to parse the source code and generate documentation in html and LaTeX formats.Step II - create a configuration file by running doxygen -g, which generates a config file (default - Doxyfile).Step I - annotate source code with special comments or special comment blocks.Working with Doxygen basically involves these three steps: It offers a practical solution to the problem of generating and maintaining source code documentation.Since the documentation is extracted directly from the source, it is much easier to keep the documentation in sync with the source code.visualize relationships between between various elements by means of include dependency graphs, inheritance diagrams, collaboration diagrams etc.ĭoxygen - the executable doxygen is the main program that parses the sources and generates documentationĭoxywizard - is a graphical front-end for editing the configuration file which is used by doxygen and for running doxygen in a graphical environment.quickly extract code structure from undocumented source files, which is useful for navigating large code bases.LaTeX, man pages) from a set of documented source files generate an on-line documentation browser (in HTML) and/or an off-line reference manual (e.g.It recognizes special comment blocks or structural commands in the source file to generate documentation in HTML or LaTeX formats.ĭoxygen offers the following capabilities: ! A class that simulates a bag of popcorn.Doxygen is the de facto standard tool for generating documentation from annotated C/C++ sources. Thus, to document a BagOfPopcorn class with both a brief and a detailed description, one could do something like the following: Note that unless you set 'JAVADOC_AUTOBRIEF = NO' in your config files (which I always do :), the JavaDoc versions will try to perform some funky magic behind your back and treat the first sentence in a JavaDoc comment up to the first period as the brief description if you think this is a good thing, just leave your config files alone :)Īt any rate, when Doxygen parses through your files, it applies the descriptions in your Doxygen comments to the immediately preceding declaration or definition in the source file. Each description is optional, but an item may have no more than one of each type of description. Each comment represents a description for some entity in your code (meaning a class, or a function, or a variable, etc.), and there are two types of descriptions: brief and detailed. The things I'm going to cover here are just the basic meat-and-potatoes parts of Doxygen that I use on a day to day basis for anything else, please consult the online Doxygen manual it's really quite handy :).ĭoxygen comments come in two flavors: JavaDoc style or Qt style. Well, just to spite all of us non-believers, here I am with a shiny new tutorial on documenting your source code with Doxygen. So I'm sure a number of you out there were a bit skeptical as to whether or not I'd be able to churn out two Doxygen newsletter articles in a row (I sure didn't think I'd manage :).
