thinking about. Just for a look, don't try to run it. I started with json
and yaml support for metadata definition. We can easily add another
supported syntax if needed but these should be enough. Look at
https://github.com/flaupretre/php-ext-gen/tree/develop

Would it not be better to work on one only?

Also I am really not a fan of yaml&co to generate C code but having
critical parts in C and everything else in straight php :)
