Since the article introducing Concierge rambled somewhat, here's a sample Concierge Rails app.

Download the sample.

Installation

$ sudo gem install concierge

Make sure you have Rails 1.2.3 and Sqlite3 installed.

Running The Greeter

You might like to run the sample app first as proof this stuff works:

$ cd ~/Projects
$ wget http://rubyforge.org/frs/download.php/21986/greeter.tgz
$ tar xzvf greeter.tgz
$ cd greeter
$ script/server
$ open http://localhost:3000/greetings

Enjoy your greeting.

The Code

Yes, it's the hello world service. The relevant bits follow.

config/environment.rb

require 'concierge'
CodeRhythm::Concierge::Loader.configure do |config|
  config.service_config_path = "#{RAILS_ROOT}/config/services"
  config.env                 = RAILS_ENV
end
Dependencies.load_paths.unshift "#{RAILS_ROOT}/lib/services"

On edge rails config/initializers/concierge.rb is probably a better choice.

config/services/greeter.yml

development:
  greeting: hello
test:
  greeting: hola
production:
  greeting: buenos dias

app/controllers/application.rb

class ApplicationController < ActionController::Base
  include CodeRhythm::Concierge::Consumer
end

app/controllers/greetings_controller.rb

class GreetingsController < ApplicationController
  consumes_service :greeter
  def index
    render :text => greeter.greet
  end
end

lib/services/greeter.rb

class Greeter < CodeRhythm::Concierge::Provider
  provides_service :greeter
  def greet
    config.greeting
  end
end
