First write your shared library in go, then load it into your ruby  
program using either ruby/dl (part of the MRI standard library) or  
ruby-ffi (available as a gem and supported under both MRI and JRuby).

You will also have to figure out how go mangles function names to be  
able to call into the library and there may well be runtime aspects of  
the go language which are incompatible with current ruby  
implementations.

Happy hacking 🙂

Indeed. But if you can build a shared library in the first place  
(something I can’t comment on one way or the other) then both ruby/dl  
and ruby-ffi can attempt to load it. Whether or not that’s easy or  
stable we’ll only know for sure when someone tries 🙂
