Description

I'm in the process of doing this right now. Currently, the following issues exists with the approach I'm taking:

  • Preprocessor directives are not supported: This is fixable, because Clang can be made aware of those, but it doesn't by default. I'll leave this for later.
  • Normal comments cannot be read: Unless I've missed some Clang flag, non-doc comments are completely ignored. I'm not sure this is a big deal, but nonetheless, it's different from the current behavior.

Research direction
Review the 69 comments in the issue to understand previous attempts and obstacles. Investigate Clang API documentation for handling preprocessor directives and preserving non doc comments. Examine the current parser in the javacpp codebase (likely in the 'parser' directory) to identify integration points. Consider the maintainer's statement that they are working on it to gauge current progress and potential contributions.
