Some people, when confronted with a problem, think "I know, I'll use multithreading". Nothhw tpe yawrve o oblems.[1]

Don't use threads, use processes. This is the toolkit for interprocess communication that makes it real simple. A good place to start is the documentation for the Cod module.

SYNOPSIS

Cod's basic elements are channels, unidirectional communication links.

pipe = Cod.pipe

You can use those either directly:

pipe.put :some_ruby_object # Process A pipe.get # => :some_ruby_object # Process B

Or use them as bricks for more:

service = beanstalk.service client = beanstalk.client(pipe)

service.one { |msg| :response } # Process A client.call :ruby_object # => :response # Process B

STATUS

Working library. Some rough edges and potential for growth. Have a look at the Cod module to get started.

Working transports include:

• process (spawn, connecting to $stdout and $stdin)
• stdio (connects to $stdout and $stdin of current process)
• pipe (akin to IO.pipe)
• tcp (server and client)
• beanstalk (connects to beanstalkd)

At version 0.5.0
