passing events from erlang to Clojure

Question

I'm looking for a way to pass events back and forth between Clojure and erlang.

• has someone done this before?
• how should I encode the (immutable) messages in a flaxable general way?
• Should IPC be used for this? what sort?
• where has this gone wrong for you in the past?

Answer 1

You've got lots of options as long as you use a socket (e.g. TCP/IP).

• Have you considered JSON?
• XML?

I can't say I've done Clojure <--> Erlang bridges before but "talking" to Erlang in JSON/XML is sufficiently painless.

Of course you can use the erl_interface (binary exchange protocol) but then you'll need (probably unless there is a lib for this) to craft a marshaller for this in Clojure.

Answer 2

You could use jinterface from clojure and be able to act as an Erlang node and send out multiple Pids associated with your node, in the Erlang cluster.
