But clang_findReferencesInFile gets the details right, and will be updated as the underlying C++ ASTs change, so users of that interface get more accurate results with less work. Oh, and it performs way better, too, because it can use the richer C++ ASTs to optimize its traversal.</div><div><br></div><blockquote type="cite"><div dir="ltr"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div style="">Perhaps optionally building on a comment cursor API foundation, we could provide stable high-level APIs like this to find all the comments in a file, or all the comment nodes of a particular type in a comment, etc.</div>
