Public Class methods

Add routes to a controller class

  module Capcode
    class Hello < Route '/hello/(.*)', '/hello/([^#]*)#(.*)'
      def get( arg1, arg2 )
        ...
      end
    end
  end

In the get method, you will receive the maximum of parameters declared by the routes. In this example, you will receive 2 parameters. So if you go to /hello/world#friend then arg1 will be set to world and arg2 will be set to friend. Now if you go to /hello/you, then arg1 will be set to you and arg2 will be set to nil

If the regexp in the route does not match, all arguments will be nil

Session hash

[Source]

     # File lib/capcode.rb, line 343
343:         def session
344:           @env['rack.session']
345:         end

Set global configuration options

Options :

  • :port = Listen port (default: 3000)
  • :host = Listen host (default: 0.0.0.0)
  • :server = Server type (webrick or mongrel)
  • :log = Output logfile (default: STDOUT)
  • :session = Session parameters. See Rack::Session for more informations
  • :pid = PID file (default: $0.pid)
  • :daemonize = Daemonize application (default: false)
  • :db_config = database configuration file (default: database.yml)
  • :static = Static directory (default: the working directory)
  • :root = Root directory (default: directory of the main.rb) — This is also the working directory !
  • :verbose = run in verbose mode
  • :auth = HTTP Basic Authentication options

It can exist specifics options depending on a renderer, a helper, …

Example :

  module Capcode
    set :erb, "/path/to/erb/files"
    ...
  end

[Source]

    # File lib/capcode/configuration.rb, line 27
27:     def set( key, value )
28:       config[key] = value
29:     end

This method allow you to use a Rack middleware

Example :

  module Capcode
    ...
    use Rack::Codehighlighter, :coderay, :element => "pre",
      :pattern => /\A:::(\w+)\s*\n/, :logging => false
    ...
  end

[Source]

     # File lib/capcode.rb, line 485
485:     def use(middleware, *args, &block)
486:       middlewares << [middleware, args, block]
487:     end
