How exactly does Tryruby work?

[golubovsky]

Hi,

I have always been curious: how does Tryruby (http://
tryruby.hobix.com/) work: does it contain a Ruby interpreter coded in
Javascript, or is it just a frontend to some web service?

PS I haven't tried to reverse-engineer that site understanding that
somebody might want not to disclose their ideas, but I think my
general question might be answered.

Thanks.

There's a patched interpreter running behind. Google for
FreakyFreakySandbox. _why patched the interpreter to separate the
individual session from each other. That interpreter is connected to
the webserver using drb. (This is what I remember from various mailing
list/blog posts, so I don't guarantee anything ;-)

Mostly javascript that talks to the server (ajax...)
Just view the page source when it loads in your browser.

There's a 13-year-old kid watching a log file with "tail -f". When a
request comes in, he reads it off the monitor and types it into a Mac
Mini running "irb". Then he copies the "irb" results into an HTML page
source that he's editing in "vi" and does ":w!" to update the HTML!

"And what's behind that vi window, making that work?"

"You can't fool me, Mr. James, it's teenagers all the way down!"

Nope. Prison labor. Most do license plates. A few do vi.

Yup. That's what happened to the guys from "Office Space" after they
were caught.

No, no NO!

It's a couple of *cats* and every time one of them types :w! they get
a dose of chunky bacon!

Tried View Source on the web page? It's some of the most readable
JavaScript I've seen. Looks like it uses a number of support
scripts (mouseApp.js, mouseIrb.js, etc.) which you can download and
look at just by pointing your browser at them.

Hint: take a look at the fireOffCmd function in mouseIrb.js
