There is no wiki either.

And the Preprocessor seemed to keep comments by default, and can not be disabled!

CppReader behaves as a Java Reader. Preprocessor has its own lexer-like API if you want to use it directly. Keeping comments can be enabled or disabled using Feature.KEEPCOMMENTS or Feature.KEEPALLCOMMENTS. Overall documentation is available here: https://shevek.github.io/jcpp/docs/javadoc/

If I use Preprocessor directly, Feature.KEEPCOMMENTS or Feature.KEEPALLCOMMENTS will not take effect and pp.token() willl always keep comments. In order to disable comments, I have to use LexerSource or CppReader.

Please don't reuse issues for new questions. A minimal code sample would be great so reproduce your bug report.

Re: KEEPCOMMENTS: I didn't check again, but that's probably true, but it's fairly easy to filter the returned token stream by type yourself. Filtering comments within the API is only really important if you don't have access to the token stream (and hence types), as in CppReader. I don't think LexerSource has anything to do with comments.
