Correctly initialize embedded Ruby interpreter. #137

Closed cfis closed 3 years ago

cfis commented 3 years ago

Embedding ruby requires more than just calling ruby_init - that always leads to exceptions on windows since ruby_sysinit is not called. This patch updates Ruby to be correctly initialized for tests. It also makes sure Ruby is only initialized once.

Thanks! Curious, what are you using Rice for?

I'm currently wrapping our company's core C++ engine using PyBind11 - which has worked really well. Very impressive library.

Having done a lot of Ruby work previously I was curious how hard it would be to do the same in Ruby. I vaguely knew about Rice and decided to give it a try in me free time. It also is a good way for me to improve my C++ metaprogramming skills (I've been working on updating the wrapper function code but keep coming up with better ways of doing it as I learn more).

Awesome. The contributions you're making are appreciated, thanks for modernizing some of this!
