Embedding 1.9

Dave Thomas

1/7/2008 9:44:00 PM

Folks:

I'm working on the "Extending Ruby" chapter (now an appendix) for the
third PickAxe, and I'm finding a whole bunch of conflicting
information. Reading the source, it seems like there's no canonical
way of embedding Ruby in a C application. I have lots of alternatives
that _seem_ to work, but I want to be more authoritative than that.

Does anyone have any pointers to stuff that would help?


Thanks



Dave

Mark:

I don;t believe it has Ruby 1.9, though.

Are you manually defining the TAG_xxx values somewhere? eval_intern.h
isn't installed onto the user side on my box.

Dave,
Those are defined locally in if_ruby.c, that seems to be the convention
as the tcltk extension does the same. I wonder if those should be pushed
into ruby.h to ease embedding...?

That'd get my vote. I've copied core on this..

I submitted a bug for this a while ago:

http://rubyforge.org/tracker/?func=detail&atid=1698&aid=13838&gr...

I see no reason for this to be an opaque value.

Currently I use the #ifndef trick to get the TAG_ macros.
