I am trying to write some open source plugins for FileMaker Pro, but
I’d rather write them in Ruby rather than C or C++ which is what
FileMaker requires.
Someone else has written a C++ wrapper for Java to do what I’m doing,
but there isn’t one for Ruby. Anyone interested in looking at an
example document describing the FileMaker plugin API and helping me?
No pressure.

Use rb++ or Rice to make C++ extensions for Ruby:
http://rbplusplus.rubyforge.org
http://rice.rubyforge.org
There is also SWIG for making C extensions:
http://www.swig.org
RubyInline might also be applicable:

No. That’s what computers (running SWIG) are for.

Swig should work, just make sure you have a recent version (earlier
versions didn’t work as well with Ruby). You might check out the
rbplusplus project as well:
