Compiling to .class files

Ruby JRuby
1

Hi,

I’m rather confused by the numerous options for generating .class files
from
Ruby classes. I’d like to be able to reference Ruby classes from Java
code.

compiler2, ruby2java, and jrubyc all seem to have this functionality,
and
(so far) I’ve not had much success with any of them (possibly due to
version
skew among the various gems).

Could someone clue me in please, where should I start? Which of these
tools
should I use?

Thanks!

Yes, the new jrubyc --java support is the path forward for Java class
generation. It’s still a work in progress, but I think the only
feasible way to generate real Java classes from Ruby classes (right
now) is to introduce some mostly-static syntax.

Those of you interested in “ruby2java” or “compiler2” should have a
look at the linked article and let us know what you think.
