  • 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}[http://github.com/glejeune/Capcode.more]. Each plugin is a gem that's can be installed separately.

SYNOPSIS:

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

module Capcode
  class Hello < Route '/hello'
    def get
      "Hello World #{Time.now} !"
    end
  end
end

Capcode.run( )

Running Capcode Apps

Create model

require 'rubygems'
require 'capcode'
require 'capcode/base/dm' # or require 'capcode/base/couchdb'

class Story < Capcode::Base
  include Capcode::Resource

  property :id, Integer, :serial => true # only with DataMapper !
  property :title, String
  property :body, String
  property :date, String
end

See examples/blog-dm.rb and/or examples/blog-couchdb.rb for complete examples.

Create View

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

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

module Capcode::Views
  def time
    "Hello world #{@t}"
  end
end

Capcode.run( )

Create Helper

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

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

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

module Capcode::Views
  def time
    "Hello world " + bold { @t }
  end
end

Capcode.run( )

Render with Markaby

# file: sample.rb
require 'rubygems'
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

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

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”
