Re: Where can I find the doxyfile?

>> We also have a handful of .cpp files.
Fortunately, our .cpp files are simple and do not include C++ specific features.
We shouldn’t have any problem adding .cpp to the filter list.

At some point it will be necessary to support general C++, but I wasn’t planning to do it yet.

I’ll update it to Postgres commenting. The filter started as a standalone project.

“build time error messages” occur after typing “ninja”.

Documentation is usually produced long after meson setup messages have been forgotten.
It is much more useful to see “Please install the doxygen program” after typing “ninja doxygen”
than to see “target not supported”, or to have to look through the setup log.

It’s personal preference, but I think the sgml docs should display a similar message.

Got it. Thanks.
