Re: Calling Lua from C

[Michael Gogins <michael.gogins@...>]

I call Lua from C++, and I just use the Lua C API to do it. I don't
find manipulating the Lua stack that troublesome, it seems easier to
use than the Python C API. But then, I'm not calling oodles and oodles
of Lua functions and classes, just a few.

Regards,
Mike
