Question

I’m currently working on large C++ Qt based project which is a about to go under a major re-factor of its public API and it would be nice to have a tool that can generate a report on which methods have been added or removed from build to build.

I know there is a tool for Java to do this and I think there might be one for .NET but I couldn’t, after a bit of searching, find anything for C++.

Does one exist. Cross platform would be nice, or if only in Linux that would be fine too.

If you use Doxygen or some similar tool to document your API then you can diff the table-of-contents.

• This is something you should be doing anyway.
  • (You can also tell Doxygen to find undocumented functions.)
• You can apply it easily to ancient checkins without changing anything.
• The Doxygen and its ilk know enough about the language to be sensitive to private and public.
• This solution can be applied to many languages and is not dependent on a particular IDE.
• No third-party software is required (given that you already have a documentation generator).
