With RubyJS you can transform a subset of Ruby into Javascript code.
What works?
* Classes, modules, inheritance
* Instance methods, class methods
* Exceptions (rescue/ensure)
* Meta-programming stuff like 'attr_reader'
(any meta-programming stuff works that does not appear inside methods)
* Iterators, yield
* "require" (with platform-specific extension ala Google Webtoolkit)
* Inline Javascript code
* Some kind of compile-time method lookup
* Numbers, String, Array, Hash, Proc (a lot of functionallity is missing!)
* Testing with Rhino-JS
* A lot more
There is a lots of room for optimizations and improvement
Is there a way to download it without installing Mercurial? I looked around the website given but didn't see anything. I am interested in seeing the code it produces.
Thanks,
Dan

yes but how to interact with the browser window, for example, say i have
a :
<pre id="STDOUT"></pre> in the html document and i want to redefine ruby
puts like this :
def puts(str)
document.getElementById('STDOUT')['inneHTML'] += str + "\n"
end
if i do that into your HelloWorld class i get errors :
Well, does it work in Ruby? NO! So it doesn't work in RubyJS as well
It's a bit more advanced than converting "document" from Ruby plainly
into "document" in Javascript.
If you want to insert Javascript code directly into your Ruby code, use
backticks:
def puts(str)
`document.getElemementById('STDOUT')['innerHTML'] += str + "\n"`
end
In the next step, I've planned to port Google's Webtoolkit (or Python Pyjamas)
to RubyJS.
method_generator.rb:1040:in `method_missing': Not implemented
(RuntimeError)
[...]
is their a way to let RubyJS knows that "document.getElementById..." is
allready JS ???
See above

Michael

Sorry! Actually it should be:
def puts(str)
`document.getElemementById('STDOUT')['innerHTML'] += #<str> + "\n"`
end
Notice the #<str>, which correctly converts variable names.

Very cool! I'm played with Google Web Toolkit and really like it ... except for the part where you have to code in Java to use it. A Ruby equivalent would be wonderful!

I got the same error with that writing :

from ../bin/rubyjs_gen:82
