i’ve downloaded a demo of rb2js.rb (ruby to javascript) from  
[http://po-ru.com/diary/convert-ruby-to-javascript/](http://po-ru.com/diary/convert-ruby-to-javascript/)

this demo works great.

then i’ve try to use rb2js.rb to convert a Color class (which has been  
tested within ruby) from ruby to javascript, the conversion fails  
because of :

rb2js:198:in ‘handle’: can’t perform method dispatche without explicit  
receiver (RB2JS::Unhandled)

althought i did mimic, as far as possible, the Paul B. way of doing  
that.

the ruby file i want to convert into javascript is here :

[http://www.yvon-thoraval.com/ruby2js/demo/color.rb](http://www.yvon-thoraval.com/ruby2js/demo/color.rb)

the output being in :

[http://www.yvon-thoraval.com/ruby2js/demo/color.rb.txt](http://www.yvon-thoraval.com/ruby2js/demo/color.rb.txt)

in case someone else uses rb2js.rb…
