How can I make Doxygen not document my include guard?

Question

I'm using Doxygen 1.8.13 on a C++ project.

Generally, I want Doxygen to document my macros. However, I obviously don't want it documenting my header file include guards:

#ifndef FOO_H_
#define FOO_H_
... etc ...
#endif // FOO_H

... but Doxygen, by default, does add a documentation entry for it. I know I can work around this with:

///@cond
#ifndef FOO_H_
#define FOO_H_
///@endcond
... etc ...
#endif // FOO_H

But I don't want to have to add two useless lines to every single header file! Is there anything I can do?

Answer 1

From the documentation:

EXCLUDE_SYMBOLS The EXCLUDE_SYMBOLS tag can be used to specify one or more symbol names (namespaces, classes, functions, etc.) that should be excluded from the output. The symbol name can be a fully qualified name, a word, or if the wildcard * is used, a substring. Examples: ANamespace, AClass, A -Class::ANamespace, ANamespace::*Test

So in your case e.g. setting in the Doxyfile:

EXCLUDE_SYMBOLS         = *_H_
EXCLUDE_SYMBOLS        += *_HPP_

or

EXCLUDE_SYMBOLS         = *_H_ \
                          *_HPP_
