Posted by Aaron Patterson – January 15, 2008

The Mechanize library is used for automating interaction with websites.
Mechanize automatically stores and sends cookies, follows redirects,
can follow links, and submit forms. Form fields can be populated and
submitted. Mechanize also keeps track of the sites that you have visited as
a history.

Happy New Year! (RKelly Progress report)

I’ve just started getting the runtime working with RKelly. Its working well enough at this point that I was able to execute my earlier Fibonacci example. I’ve added a method to the runtime that allows you to define ruby functions that may be called from inside javascript. For example, the alert function in the following example is defined in ruby and delegates to puts.

runtime = RKelly::Runtime.new

runtime.define_function(:alert) do |*args|
  puts(*args)
end

runtime.execute(<<END
function f(n) {
  var s = 0;
  if(n == 0) return(s);
  if(n == 1) {
    s += 1;
    return(s);
  } else {
    return(f(n - 1) + f(n - 2));
  }
}
alert(f(20));
END
)

Here is the execution time with ruby 1.8.6 on my machine:

[aaron@mac-mini rkelly]$ time ~/.multiruby/install/1.8.6-p111/bin/ruby -I lib test.rb
6765

real 0m54.332s
user 0m53.913s
sys 0m0.336s
[aaron@mac-mini rkelly]$
[/sourcecode]

Same code, same machine, but with ruby 1.9.0:


[aaron@mac-mini rkelly]$ time ~/.multiruby/install/1.9.0-0/bin/ruby -I lib test.rb
6765

real 0m20.863s
user 0m20.678s
sys 0m0.142s
[aaron@mac-mini rkelly]$
[/sourcecode]

I need to get loops working next!
