Okay, you can try out Camping 1.3.69 from gems. Camping is a microframework. Railsish aesthetics for wee CGIs.

 gem install camping --source code.whytheluckystiff.net

Sessioning

To get sessions working for your application:

1. require 'camping/session'
2. In your application’s create method, add a call to Camping::Models::Schema.create_schema
3. Throughout your application, use the @state var like a hash to store your application’s data.

More notes about this at CampingSessions on the wiki.

Helpers#URL

Builds a complete URL to a controller route or a path, returning a URI object.

Assuming the Hoodwink.d app is mounted at http://localhost:3301/hoodwinkd/, in a controller or view you’ll see the following results:

  >> URL()
  => (URI:http://localhost:3301/hoodwinkd/)
  >> self.URL
  => (URI:http://localhost:3301/hoodwinkd/)
  >> URL(Static, 'js/prototype.js')
  => (URI:http://localhost:3301/hoodwinkd/static/js/prototype.js)
  >> URL("/boingboing.net/setup")
  => (URI:http://localhost:3301/hoodwinkd/boingboing.net/setup)
  >> URL("http://google.com")
  => (URI:http://google.com/)

Service Overrides

Adding stuff like sessioning and authentication demands hooks on the controller. Rails uses hooks like before_filter to do this. Camping doesn’t have bytes to spare to make this happen, but things have been re-stacked to let you slide in new service methods which intercept all controller calls.

 class LoginError < Exception; end
 module ClownsOnly
   def service(*a)
     unless @state.occupation == :clown
       raise LoginError, "For clown's eyes only." 
     end
     super(*a)
   end
 end

This service method can be slid into your application’s top module like so:

 Camping.goes :Blog

 module Blog
   include ClownsOnly
 end
