DESCRIPTION

widgetz.rb aims to fix two problems with factoring and abstracting
html
generation in rails using the normal ‘helper’ methodolgy:

 1) helper methods are purely procedural and provide no state.

ruby is an
object oriented language and we like to use objects to abstract
things
where possible. widgetz lets you do just that. some people
call this
encapsulation.

 2) by using the normal rendering chain in rails, widgetz makes

sure you
get a nice stack stace from the location in the widgetz template
where
you used ruby’s power blow your leg off instead of some esoteric
message
from an anonymous module you barely knew.

widgetz are essentailly bags of data that use a controller to render
themselves. all the state of the widget is made available in the
view as
local variables, while the normal @variables set in a controller
remain
visible as normal. one special local variable, ‘widget’, is set
in the view’s
local vars so you have a handle on the widget in order to use it
for some evil
purpose.

SAMPLE

app/controllers/sample_controller.rb

 def c
   @var = 42
   @c = widget 'c'

   render :layout => 'application', :inline => <<-rhtml
     var: <%= @var %>

     <hr>

     <%= @c %>
   rhtml
 end

lib/widgets/c.rb

 Widget 'c' do
   attribute 'var' => 'forty-two'

   def answer
     42.0
   end
 end

app/views/widgets/c.rhtml

 controller var : <%= @var %>          <br>
 widget var     : <%= var %>           <br>
 widget method  : <%= widget.answer %> <br>

output

 var: 42
 ----------------------
 controller var : 42
 widget var     : forty-two
 widget method  : 42.0

we can deny everything, except that we have the possibility of being
better. simply reflect on that.
