Configuration files

[linqueta]

About configuration or settings files, my suggestion are these:

For core settings, we can have a settings.yml, like:

Path: config/activemessage/settings.yml

settings:
  aws:
    access_key_id: '<%= ENV['AWS_ACCESS_KEY_ID'] %>'
    secret_key: '<%= ENV['AWS_SECRET_KEY'] %>'
    region: '<%= ENV['AWS_REGION'] %>'
    account_id: '<%= ENV['AWS_ACCOUNT_ID'] %>'
    # Any kind of things that others gem for this organization needs
default:
  queues:
    # Settings for all queues
  topics:
    # Settings for all topics

For queues:

Path: Path: config/activemessage/queues/*.yml

default:
  queues:
    # Settings for all queues in this file
  topics:
    # Settings for all topics in this file
queues:
  - ...

For topics:

Path: Path: config/activemessage/topics/*.yml

default:
  queues:
    # Settings for all queues in this file
  topics:
    # Settings for all topics in this file
queues:
  - ...

---

About Configuration class, I really think that's it have to be open for others gems of this organization, so, this gems will can write data there.

My suggestion is something like that:

module ActiveMessage
  class << self
    def self.configurations
      @configurations ||= build_configurations!
    end

    private

    def build_configurations!
      # Call Reader and build configurations...
    end
  end
end

module ActiveMessage
  class Configuration
    attr_accessor :kind, :data

    def initialize
      @nested = []
    end

    def add_configuration(configuration)
      @nested << configuration
    end
  end
end

Using this way, we can have some kinds, like:

• aws
• queue
• topic
• subscription
• default-queue
• default-topic
