Hi all,

After 9 months, the second incarnation of RubyJS is out (a complete  
rewrite).  
RubyJS compiles Ruby to Javascript and tries to be as efficient as  
possible  
without sacrifying Ruby’s beauty.

This is a pre-release. I hope I can import some local code that lies  
here around  
till RubyConf.

A small example:

# hw.rb

require ‘rwt/DOM’

class HelloWorld  
def self.main  
out = DOM.getElementById(‘out’)  
DOM.setInnerText(out, ‘hello world’)  
end  
end

say hello

Compile it:

rubyjs\_gen --main HelloWorld hw.rb \> hw.js

And start index.html inside your browser.  
Oh, and don’t forget the optimization flags:

rubyjs\_gen --show-options

# What works?

- Most if not all Ruby constructs!
- Accessing/modifying DOM in your browser
- JSON

# What is missing?

- The port of Google Web Toolkit is not yet completed.
- Applications 😉
- A lot of methods in the core library

# DOWNLOAD

It’s available from:

[http://ntecs.de/hg-projects/rubyjs/](http://ntecs.de/hg-projects/rubyjs/)

Best use Mercurial ([www.selenic.com/mercurial](http://www.selenic.com/mercurial)) to check it out:

hg clone static-[http://ntecs.de/hg-projects/rubyjs/](http://ntecs.de/hg-projects/rubyjs/)

Have fun and see you at RubyConf!

Regards,

Michael
