\section knowproblems Known Problems
<ul>
<li>Doxygen is <em>not</em> a real compiler, it is only a lexical scanner.
This means that it can and will not detect errors in your source code.
<li>Doxygen has a build in preprocessor, but this works slightly different than
the C preprocessor. Doxygen assumes a header file is properly guarded against
multiple inclusion, and that each include file is standalone (i.e. it could be placed
at the top of a source file without causing compiler errors). As long as this is
true (and this is a good design practice) you should not encounter problems.
<li>Since it is impossible to test all possible code fragments, it is
very well possible, that some valid piece of C/C++ code is not handled
properly. If you find such a piece, please send it to me, so I can
improve doxygen's parsing capabilities. Try to make the piece of code
you send as small as possible, to help me narrow down the search.
<li>Doxygen does not work properly if there are multiple classes, structs
or unions with the same name in your code. It should not crash however,
rather it should ignore all of the classes with the same name except one.
<li>Some commands do not work inside the arguments of other commands.
Inside a HTML link (i.e. \<a href="..."\>...\<a\>) for instance
other commands (including other HTML commands) do not work!
The sectioning commands are an important exception.
<li>Redundant braces can confuse doxygen in some cases.
For example:
\verbatim
void f (int);
\endverbatim
is properly parsed as a function declaration, but
\verbatim
const int (a);
\endverbatim
is also seen as a function declaration with name
<code>int</code>, because only the syntax is analyzed,
not the semantics. If the redundant braces can be detected, as in
\verbatim
int *(a[20]);
\endverbatim
then doxygen will remove the braces and correctly parse the result.
<li>Not all names in code fragments that are included in the documentation
are replaced by links (for instance when using \ref cfg_source_browser "SOURCE_BROWSER" = `YES`)
and links to overloaded members may point to the wrong member.
This also holds for the "Referenced by" list that is generated for
each function.
For a part this is because the code parser isn't smart enough at the
moment. I'll try to improve this in the future. But even with these
improvements not everything can be properly linked to the corresponding
documentation, because of possible ambiguities or lack of
information about the context in which the code fragment is found.
<li>It is not possible to insert a non-member function f in a class A
using the \ref cmdrelates "\\relates" or \ref cmdrelatesalso "\\relatesalso"
command, if class A already
has a member with name f and the same argument list.
<li>There is only very limited support for member specialization at the
moment. It only works if there is a specialized template class as
well.
<li>Not all special commands are properly translated to RTF.
<li>Version 1.8.6 of dot (and maybe earlier versions too) do not
generate proper map files, causing the graphs that doxygen generates
not to be properly clickable.
<li>PHP only: Doxygen requires that all PHP statements (i.e. code) is
wrapped in a functions/methods, otherwise you may run into parse problems.
</ul>
\section howtohelp How to Help
The development of doxygen highly depends on your input!
If you are trying doxygen let me know what you think of it (do you
miss certain features?). Even if you decide not to use it, please let me
know why.
\section bug_reports How to report a bug
Bugs are tracked in GitHub's <a href="https://github.com/doxygen/doxygen/issues">issue tracker</a>.
Before submitting a
<a href="https://github.com/doxygen/doxygen/issues/new">new bug</a>,
first <a href="https://github.com/doxygen/doxygen/issues">search</a>
through the database if the same bug has already been submitted by others.
If you believe you have found a new bug,
please <a href="https://github.com/doxygen/doxygen/issues/new">report it</a>.
If you are unsure whether or not something is a bug, please ask help
on the <a href="http://sourceforge.net/mail/?group_id=5971">users mailing list</a>
first (subscription is required).
If you send only a (vague) description of a bug, you are usually not very
helpful and it will cost me much more time to figure out what you mean.
In the worst-case your bug report may even be completely ignored by me, so
always try to include the following information in your bug report:
- The version of doxygen you are using (for instance 1.5.3, use
`doxygen --version` if you are not sure).
- The name and version number of your operating system (for instance
Ubuntu Linux 18.04 LTS)
- It is usually a good idea to send along the configuration file as well,
but please use doxygen with the <code>-s</code> flag while generating it
to keep it small (use <code>doxygen -s -u [configName]</code> to strip
the comments from an existing configuration file).
- The easiest (and often the only) way for me to fix bugs is if you can
attach a small example demonstrating the problem you have to the bug report, so I can
reproduce it on my machine. Please make sure the example is valid
source code (could potentially compile) and that the problem is really
captured by the example (I often get examples that do not trigger the
actual bug!). If you intend to send more than one file please zip or tar
the files together into a single file for easier processing.
Note that when reporting a new bug you'll get a chance to attach a file to it
only \e after submitting the initial bug description.
You can (and are encouraged to) add a patch for a bug. If you do so
please use PATCH as a keyword in the bug entry form.
If you have ideas how to fix existing bugs and limitations please discuss them on
the <a href="http://sourceforge.net/mail/?group_id=5971">developers mailing list</a>
(subscription required). Patches can also be sent directly to dimitri@stack.nl if
you prefer not to send them via the bug tracker or mailing list.
For patches please use
"diff -uN" or include the files you modified. If you send more than
one file please tar or zip everything, so I only have to save and download
one file.
