Channels for ruby

A complete implementation of channels for Ruby, including size and close.

How?

The usual gem insall channel, or gem channel in your Gemfile.

require 'channel'

c = Channel.new
go -> { c << 'Hello, world!' }
puts c.recv

Why?

While some packages already exist, many fail at providing a thorough implementation, often limited to send/recv, and most critically, all missing close support. A complete implementation makes channels much more useful, as most patterns rely much more details than simply send/recv.

To prove this point and to serve as a nice tutorial anyway, some examples ported over from Go by example are included in examples.

• channels
• channel buffering
• channel synchronization
• channel direction
• select
• timeouts
• non-block channel operations
• closing channels
• range over channels
