FWIW, I don't have a strong preference for either FFI or Jacob-based, though the Jacob-based approach pushes a lot of the native binding stuff into someone else's court (i.e. if we just use Jacob, we don't have to monkey with the FFI binding hassles and may be 90% done already).
I do have a strong preference to not duplicate work :) If Brian's got a good solid start using something like Jacob, it would probably be the best use of time to help him finish it. I could certainly be convinced otherwise, but depending on someone else's known-working COM bridge seems like a good thing to do... - Charlie On Wed, Mar 3, 2010 at 10:23 AM, Brian <brian.p.mcdev...@gmail.com> wrote: > Hi Joseph, > Take a look at the win32ole project I started on github.com/bpmcd/win32ole > This is a similar effort to your proposition. > > On Mar 3, 2010, at 9:47 AM, Joseph Athman <jjath...@gmail.com> wrote: > > I really didn't have a major reason for trying to implement this, I just > figured it is something JRuby should have since MRI has it.
