Hi Davide,
The idea is to provide Eo with introspection and automatic bindings
generation.
I made some PoC, and can generate bindings for Python and JS -
elev8. (elev8 is javascript runtime based on Google's v8 js engine).
I scan C -souces for Eo classes and functions definitions and
generate python(cython) code (or C++ for elev8) which compiled into
extern module.
There are still issues to solve..
You can look at it here:
https://github.com/yakov-g/eo_bindings/blob/master/DEV_README
I can answer any questions.
And discuss how it can be properly done.
