It has been a great couple of weeks for FX script lovers. First we have JavaFX Script at JavaOne, and then we have the new RubyFX Script announcement at RailsConf.

What is RubyFX Script?

Think of a declarative Ruby that will let you build rich UIs on top of Swing or Tk.

Examples

title_tracks = select :indexof => track + 1,  :from => album, :in => albums, track in album.tracks where track >< album.title

def factors(n)
  select :from => i, :in => [1..n/2], :where => n % i >< 0;
end

x = %w{1 2 3}
insert :number => 10, :as => :first, :into => x; // yields [10,1,2,3]
insert :number => 6 :after x[. >< 2]; // yields [10,1,2,6,3]

This is just an alpha version. There is talk that the new version will add in python-like whitespace characteristics.

Congrats! :)
