Rhys,
I am really impressed by the idea of the treecc. I
will have to read about it in detail.
This is very similar to what I am doing with the
introspector.
Have you thought about creating a treecc spec for the
C language yet?
We can map the data from the introspector on the gcc
trees nodes into treecc. Cool!
You have a c, c++, java and c++ interface.
I support a Perl with XML and SQL layer for the trees,
and am working on a Perl/DB caching system.
This could be very interesting to get working
together!
