# Run this file with:
#
#   bundle exec RAILS_ENV=production rackup -p 3000 -s thin
#
# And access:
#
#   http://localhost:3000/hello/world
#
# We are using Bundler in this example, but we could also
# have used rubygems:
#
#   require "rubygems"
#
#   gem "actionpack"
#   gem "railties"
#
#   require "rails"
#   require "rails/all"

# The following lines should come as no surprise. Except by
# ActionController::Metal, it follows the same structure of
# config/application.rb, config/environment.rb and config.ru
# existing in any Rails 3 app. Here they are simply in one
# file and without the comments.
require "rails"
require "rails/all"

class MyApp < Rails::Application
  routes.append do
    match "/hello/world" => "hello#world"
  end

  # Enable cache classes. Production style.
  config.cache_classes = true

  # Here you could remove some middlewares, for example
  # Rack::Lock, AD::Flash and AD::BestStandardsSupport below.
  # The remaining stack is printed on rackup (for fun!).
  # Rails 4 will have config.middleware.api_only! to get
  # rid of browser related middleware.
  config.middleware.delete "Rack::Lock"
  config.middleware.delete "ActionDispatch::Flash"
  config.middleware.delete "ActionDispatch::BestStandardsSupport"

  # We need a secret token for session, cookies, etc.
  config.secret_token = "49837489qkuweoiuoqwehisuakshdjksadhaisdy78o34y138974xyqp9rmye8yrpiokeuioqwzyoiuxftoyqiuxrhm3iou1hrzmjk"

# This is a barebone controller. One good reference can be found here:

class HelloController < ActionController::Metal

  def world
    render :text => "Hello world!"
  end
end

# Initialize the app (originally in config/environment.rb)

# We are not loading Active Record, nor Active Resources etc.
# We can do this in any app by simply replacing the rails gem
