prototype window class helper (for ruby on rails)
I’ve been developing some helper for ruby on rails that easily lets using the well known Prototype Window Class in a rails application avoiding javascript code handling. (Abandon hope all ye who need javascript) 
Here you are a couple of usage samples.
Updated to version v0.11.0
# Prototype Window Class Helper v0.11.0
# By Jorge Díaz - http://xurde.info
# email: jorgedf@gmail.com
# Thanks to Sebastien Gruhier for his Prototype Window Class (http://prototype-window.xilinus.com/)
# Samples: http://pwc-helper.xurdeonrails.com
#Quick use:
#Reference this helper in your rails applicaction adding -> helper :prototype_window_class in your application.rb
#You must include in the template header the prototype window class javascripts and the .css theme you want to use.
#This code in your template might be enough:
# <%= stylesheet_link_tag 'default' %> (or theme you wanna use)
# <%= stylesheet_link_tag 'alert' %>
# <%= javascript_include_tag :defaults %>
# <%= javascript_include_tag 'window'%>
class JsCode < String # for JavaScript Code Handling purpose
end
module PrototypeWindowClassHelper
#support methods
def params_for_javascript(params) #options_for_javascript doesn't works fine
'{' + params.map {|k, v| "#{k}: #{
case v
when Hash then params_for_javascript( v )
when JsCode then v
# when Array then...
when String then "'#{v}'"
else v #Isn't neither Hash or String
end }"}.sort.join(', ') + '}'
end
def content_for_window( content ) #converts
case content
when Hash then params_for_javascript( content )
when String then "'#{content}'"
else
nil
end
end
#helper methods
def link_to_prototype_dialog( name, content, dialog_kind = 'alert', options = {} , html_options = {} )
#dialog_kind: 'alert' (default), 'confirm' or 'info' (info dialogs should be destroyed with a javascript function call 'win.destroy')
#options for this helper depending the dialog_kind: http://prototype-window.xilinus.com/documentation.html#alert (#confirm or #info)

I know this is not cool at all, but today i missed some minutes in running ruby on rails on Windows Vista RC1 (i prefer to call it Unix Vista Windowed).
