Embedding several ruby interpreter instances in C?

Hello list,

the subject says it all: I know how to generally embed Ruby into a C
program. However, since ruby_init() & co just return void, I guess there
is
no way to have more than one Ruby interpreter embedded into the same
program
at a given time. Am I correct with this assumption?

TIA!

Yes. We haven’t removed all global variables yet.

Thank you! I just needed the confirmation. :slight_smile:

Didn’t Evan P. do this and provide a patch to ruby-core back in the
day (pre-sydney)?

This is a specific goal of Rubinius, and I know that it did work
with the old stackless Shotgun VM. I’m not sure about the current VM,
but if it doesn’t work, it’s probably a bug that will be fixed.

Via my magical copypasta IRC to ruby-talk gateway, Evan says:

“yes, my patch removed all global variables (it was in syndey). no, it’s
not applicable to 1.9.”
