Wow, Haskell available from inside of Ruby!
Thank you very much even for "coarse-grained interfaces"

Language integrations are very tough without a tool like this.

Nothing so clever, I'm afraid – the marshalling library forces the thunks. It _might_ be possible to get that working, but I think I'd have to stop the C FFI in a simple way. There are definitely features I care more about and will get to first.

(and your infinite list will fill memory before crashing. Sorry.)

great! very eager to try this out.
what happens with laziness? what if my haskell function returns an infinite list? should I try to wrap this in a ruby enumerator/fiber?

Thanks

Thrift is more of an RPC protocol than something for in-process communication.

oh, on the RSpec thing – I've been thinking of going the other way, too. QuickCheck on Ruby code could be interesting…

I hope it's useful to you. Patches, complaints, experience reports all gratefully accepted.

This makes me very hopeful for the LLVM version of GHC coupled with MacRuby (which is also LLVM-based).

@joevandyk Thrift is great, but like any RPC protocol has more overhead than just directly calling native code via a function call, which is what Hubris allows.

So there's very little overhead to, say, calling a compiled Haskell object in an inner loop. Thrift calls would be terribly expensive in comparison.

Cool, I liked the appearance of that boo :-) I think I'm gonna read!

Thrift (http://incubator.apache.org/thrift/) seems like it would be more useful here for cross-language communication.
