const clang::ASTContext& ast_context) {
clang::Token token;
token.setKind(clang::tok::unknown);
clang::LangOptions lang_options = ast_context.getLangOpts();

if (!clang::Lexer::getRawToken(loc, token, source_manager, lang_options)) {
if (!token.is(clang::tok::comment)) {
break;
}

{
auto range = getRange();
if (range.isInvalid())

{
//Not in the same file, or not in the main file (probably #included)
return false;
}
