How to make doxygen show warnings only for partially documented objects

Question

I'm trying to integrate doxygen in a C++ project. I'm using doxygen version 1.9.1

I would like that if a class/function had at least some documentation, doxygen enforced this documentation to be complete. See the following example

inline void hello_foo(const std::string & world)
{
  std::cout << "Hello " << world << std::endl;
}

/**
 * @brief Test incomplete documentation
 */
inline void hello_bar(const std::string & world)
{
  std::cout << "Hello " << world << std::endl;
}

Here the first function (hello_foo) has no documentation at all. The second function (hello_bar) has incomplete documentation as it's not documenting the input parameter.

I would like that doxygen generated only 1 warning on this file, i.e. the incomplete documentation in the second function. The purpose would be to enable "warning as errors", without having to first document the whole codebase.

I tried the following configurations. The other parameters are the default.

1. This was my first attempt, but it does not produce any warning from the above code

WARNINGS               = YES
WARN_IF_UNDOCUMENTED   = NO
WARN_IF_DOC_ERROR      = YES
WARN_NO_PARAMDOC       = YES

2. This configuration produces the warning I'm looking for, but it also produces warnings for the fully undocumented function.

WARNINGS               = YES
WARN_IF_UNDOCUMENTED   = YES
WARN_IF_DOC_ERROR      = YES
WARN_NO_PARAMDOC       = YES

Thank you

EDIT: It looks like WARN_NO_PARAMDOC is ignored when WARN_IF_UNDOCUMENTED=NO, but it works otherwise.

WARN_IF_UNDOCUMENTED   = YES
WARN_NO_PARAMDOC       = YES

this shows the missing param warnings

WARN_IF_UNDOCUMENTED   = YES
WARN_NO_PARAMDOC       = NO

This doesn't show them.
