My personal pattern for storing configuration info

configuration

# The personal pattern I've devised for storing module or app-wide configuration
# info in ruby projects

require 'ostruct'

module SomeApp
  class Configuration

    def self.method_missing(*args)
      config.send *args
    end    
  
    private
  
    def self.config
      @@config ||= OpenStruct.new
    end
  end
end

# all assignments/reads on SomeApp::Configuration.any_configuration_var now
# get delegated to a private OpenStruct singleton owned by SomeApp::Configuration
