Hello,
how can I share a ruby-process?
2 irb-sessions accessing the same Ruby-process? - so fork cant do for that.
I want to havwe one irb running the program,
whereas I could show the vars at runtime in the other session.
How can I do that?
thanks

Hi,
you can try DRb <http://ruby-doc.org/stdlib-2.3.1/libdoc/drb/rdoc/DRb.html>,
it is a part of ruby's standard library.

Please forgive the semi-ignorance of another newbie, but is this not the primary reason for the marshal module? I know it is used as a way of providing persistence of data, but I thought it's main intent was to provide a way of sharing data between classes and/or modules?
If this is the case why re-invent the wheel? Unless, of course, it is difficult to use for this purpose.

Take a look at pry-remote.
It doesn't quite do what you want, as it doesn't permit multiple remote
sessions, but the code isn't very long, and is easy to read. My hunch is
that you could use it as a starting point, and with a little work, you
could have it permitting multiple simultaneous sessions.

Just note , it has really poor performance and when we tried to use it for prod, it made the whole program hang .
After testing a few stuff , we used redis to share data , you can marshal objects before sending them to redis.
You can also try using stuff like 0mq , msgpack , etc..

Mah. I now mostly use Mruby. When I used MRI, DRb was often involved,
and proved solid & fit for the task. I had to learn its quirks
(calling remote methods does not automatically mean sharing data
between local and remote instances of objects). But I do not remember
associating it with hangs and crashes.

How did you use it? How can we know the issue was in DRb and not in your code?

OK - thanks for that Matthew. Have no experience in multi-session, so would not have been aware of that. Will file away for reference.
