Simple way to share a logger across a bunch of files without using a global variable

logger_example

require 'forwardable'
require 'singleton'
require 'logger'

module Silvio
  class Logger
    include Singleton
    extend Forwardable

    def_delegators :@logger, :debug, :info, :warn, :error, :fatal

    def initialize
      @logger = ::Logger.new(STDOUT)
      @logger.level = ::Logger::DEBUG
    end

  end

  module Logging
    def logger
      Silvio::Logger.instance
    end
  end

  class Foo
    include Silvio::Logging

    def do_something
      logger.debug("going to do something cool")
      logger.error("shit happened")
    end
  end
end


logger = Silvio::Logger.instance
logger.debug('foo')

Silvio::Foo.new.do_something
