Emrpc is a project mainly written in Ruby, based on the MIT license.
Modular ruby RPC library with blocking and evented API (using EventMachine)
EMRPC is a EventMachine-based remote procedure call library. It looks like DRb, but is much more efficient and provides asynchronous erlang-like interface along with blocking synchronous interface.

FEATURES
VERSION AND STATUS
This is v0.3 alpha. It is being used in several projects of my own, but is not tested on many interesting cases. It has also several issues with performance and specs stability (see TODO file).

EXAMPLES
You may try out examples using bin/emrpc IRB session. Just open the console and paste the code.
HELLO WORLD (BLOCKING API)
class HelloWorld def action "Hello!" end end
server = EMRPC::Server.new(:address => 'emrpc://localhost:4000/', :backend => HelloWorld.new) EM::safe_run(:background) { }
server.start
client = EMRPC::Client.new('emrpc://localhost:4000/') client.action == "Hello!" #=> true
HELLO WORLD (EVENTED API)
class HelloWorld include Pid def action(sender) puts "HelloWorld replies to the sender #{sender}..." sender.reply(self, "Hello!") end end
class User include Pid def connected(pid) puts "Pid #{pid} connected with the user." pid.action(self) end def reply(pid, msg) puts "Pid #{pid} replied: #{msg}" end end
EM::run do hw = HelloWorld.new hw.bind('emrpc://localhost:4000/') # bind a pid to the address
oleg = User.new
oleg.connect('emrpc://localhost:4000/') # connect to that address
end
Pid #
HELLO WORLD (EVENTED WRAPPER, MIXED API)
class HelloWorld def action "Hello!" end end
server = EMRPC::Server.new(:address => 'emrpc://localhost:4000/', :backend => HelloWorld.new)
EM::run do server.start end
class User include Pid def connected(pid) puts "Pid #{pid} connected to the user." pid.send(self, :action) end def on_return(pid, msg) puts "Pid #{pid} replied: #{msg}" end end
EM::run do oleg = User.new oleg.connect('emrpc://localhost:4000/') # connect to that address end
