DESCRIPTION:

Capcode is a web microframework

FEATURES/PROBLEMS:

0.9.3

• Major bug correction

0.9.2

• Remove JSON dependency
• Add the "HTTP code" renderer, so you can now use something like this : render 200 => "OK", :server => "Capcode", …
• Reintroduce before_filter. See example filter.rb.
• Remove mime-types dependency

0.9.1

• You don‘t need to require the renderers. This will be done by Capcode at use time.
• Major bug correction for jRuby

0.9.0

• IMPORTANT
  • THIS VERSION IS A MAJOR ENHANCEMENT : YOU MUST UNINSTALL ALL PREVIOUS VERSIONS !!!

                gem uninstall Capode --version '< 0.9.0'
    

  • Renderers and database accessors have been extracted and are now in the plugins repository. Each plugin is a gem that‘s can be installed separately.
• Important, but less!
  • Add Coffee-Script renderer
  • Update renderers options
  • Rewrite configuration
  • Bug corrections in all DB modules

0.8.9

      end
    end
  end

  module Capcode::Helpers
    def bold( &b )
      "<b>"+yield+"</b>"

      "Hello world " + bold { @t }
    end
  end

  Capcode.run( )

  require 'capcode'

  module Capcode
    class Hello < Route '/hello'
      def get
        @t = Time.now

        # This implies that capcode-render-markaby is installed !
        render :markaby => :time
      end
    end
  end

  module Capcode::Views
    def time
      # We use Markaby in Capcode::Views.time
      html do
        body do
          p {
            text "Hello World "
            b @t
          }
        end
      end
    end
  end

  Capcode.run( )

Render with Haml

  module Capcode
    set :haml, "./my_haml_views"

    class Hello < Route '/hello'
      def get
        @t = Time.now

        # This implies that capcode-render-haml is installed !
        render :haml => :time
      end
    end
  end

  Capcode.run( )

  # ./my_haml_views/time.haml
  %html
    %body
      %p
        Hello World
        = @t

Render with JSON

  # file: sample.rb
  require 'rubygems'
  require 'capcode'

  module Capcode
    class Hello < Route '/hello'
      def get
        @t = Time.now

        # This implies that capcode-render-json is installed !
        render :json => { :time => @t }
      end
    end
  end

  Capcode.run( )

Render with WebDAV

  # file: sample.rb
  require 'rubygems'
  require 'capcode'

  module Capcode

    # !!! Render file from /Users/greg/temp !!!
    class WebDav < Route '/temp'
      def get
        # This implies that capcode-render-webdav is installed !
        render :webdav => "/Users/greg/temp"
      end

      def method_missing(id, *a, &b)
        get
      end
    end

    class Index < Route '/'
      def get
        render "WebDav server acces : <a href='#{URL(Capcode::WebDav)}'>#{URL(Capcode::WebDav)}</a>"
      end
    end

  end

  Capcode.run( )

HTTP Authentication

  # file: sample.rb
  require 'rubygems'
  require 'capcode'

  module Capcode
    class Public < Route '/public'
      def get
        render "This page is not protected"
      end
    end

    class Private < Route '/private'
      def get
        http_authentication( :type => :digest, :realm => "Private part" ) {
          { "greg" => "p4ssw0rd" }
        }

        render "This page is private - Hello #{request.env['REMOTE_USER']}"
      end
    end
  end

  Capcode.run( )

Second example :

  # file: sample.rb
  require 'rubygems'
  require 'capcode'

  module Capcode

    http_authentication( :type => :digest, :realm => "Private part", :routes => ['/admin', '/private'] ) {
      { "greg" => "p4ssw0rd" }
    }

    class Public < Route '/public'
      def get
        render "This page is not protected"
      end
    end

    class Private < Route '/private'
      def get
        render "This page is private - Hello #{request.env['REMOTE_USER']}"
      end
    end

    class PrivateAgain < Route '/private/again'
      def get
        render "This page is also private - Hello #{request.env['REMOTE_USER']}"
      end
    end

    class Admin < Route '/admin'
      def get
        render "This page is private - Hello #{request.env['REMOTE_USER']}"
      end
    end
  end

  Capcode.run( )

DEPLOYMENT

With Passenger

First create the directory structure :

  my_app/
  my_app/tmp
  my_app/public

Then put your app in my_app/ and comment or remove the line with Capcode.run

Create a rack configuration file (config.ru) in my_app/

  require 'app'
  run Capcode.application()

Capcode.application take the same parameters as Capcode.run (and block too). Be carefull, if you use static files (with the static renderer) you must set the :root option (:root => File.expand_path(File.dirname(FILE)) is probably good)

You can now deploy your application like a "Rack-based Ruby application"
