goerlang/node

Implementation of Erlang node

Go-node

Implementation of Erlang/OTP node in Go

Supported features:

• Publish listen port via EPMD
• Handle incoming connection from other node using Erlang Distribution Protocol
• Spawn Erlang-like processes
• Register and unregister processes with simple atom
• Send messages to registered (using atom) or not registered (using Pid) processes at Go-node or remote Erlang-node
• Create own process with GenServer behaviour (like gen_server in Erlang/OTP)

Not supported (but should be):

• Initiate connection to other node
• Supervisors tree
• Create own behaviours
• RPC callbacks
• Atom cache references to increase throughput

Examples

See examples/ to see example of go-node and GenServer process

node's Issues

Inactive development

I forked this project and complete reworked it. So if someone need more features... welcome

Any feedback is highly appreciated

Hot code replacement

Hi I watched this http://www.youtube.com/watch?v=apZYqHPqzYo and thought it would be nice to have hot code replacement in go as well.

In Java, you have the OSGi project ( http://www.osgi.org/Main/HomePage ) and hotswap ( http://code.google.com/p/hotswap/ ), which facilitates upgrading and changing modules of your application without touching other modules.

ssh connection

Hi,
Does it work with ssh connection?

Mic

Cannot send message to golang node by pid

Erlang node can send message by {registered_name, node_name}, but cannot send message py pid. With tracing (-erlang.trace.node) i see this message in logs:

Unhandled node message (act 2): etf.Tuple{2, "", etf.Pid{Node:"relay@localhost", Id:0x3, Serial:0x0, Creation:0x2}}

Seems like switch in https://github.com/goerlang/node/blob/master/node.go#L330 does not handle messages to raw pids.

How to initiatively connect erlang node?

at least give me a idea for implement this feature

only support erl -sname?

hi,
i test it with -name with ip ,but not work,whicy way to support -name?

Client RPC

Hi

The example code shows how to expose a Go function that can be called from Erlang using RPC. Is it possible to do the opposite, i.e., call rpc:call from the Go side?

link(pid)

what about process linking?

How can golang node send message to erlang node by process_register_name?

How can golang node send message to erlang node by registed_process_name?
