Embedding 1.9

[Dave Thomas]

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

Have you checked out VIM? It has ruby embedded and provides an
interface into vim buffers from ruby. HTH. Good luck.

Mark:

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

case TAG_RAISE:
case TAG_FATAL:

Mark:

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&group_id=426

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

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