Ruby meets Go
summary
Shows that Go 1.5 buildmode c-shared/c-archive produces C-compatible .so libraries callable from Ruby using Ruby FFI and fiddle, demonstrates a working demo gem wrapping a memberlist (used by Consul/Serf) and a build flow using Rake/mkmf hacks. Explains concrete techniques: wrapping missing C macros, avoiding the usual two-copy penalty by using a zero-copy string pointer, and using a reference-count map so Ruby-referenced objects aren’t GC’d while used from Go.
