</div>Can you elaborate on those struggles? It seems to mostly be unmaintained.<br>

I would like this to eventually replace -dump-ast, if we can agree on a syntax; -dump-ast is nice for expressions, but useless for declarations.</blockquote><div><br></div><div>Craig and Zhanyong have an analogous dump output built around RecursiveASTVisitor. Its output is also structured in a form to make it easy to write FileCheck-based tests for IIRC. I believe they were intending to commit that, but had held off thinking the existing system was "Good Enough". If they can contribute this, would that be a good place to focus effort on this front? I think it is already more complete than this dumper, although I've not audited it by any means.</div></div></blockquote><br></div><div>I'd be at least interested in seeing it.</div><div><br></div><div>John.</div><br></body></html>
