You should be able to do this without JavaScript by using streaming.

To quote:
"If Sinatra is overkill for what I want, perhaps I should look into
something different."

And again, it's "Tomcat", NOT "TomCat"; precision counts, in programming and
discussions about programming :-)

Is there any reason you can't get the data direct from the process
that's writing
that file? Reading from a file being written every second seems a bit clumsy.
Just to muddy the water a bit :-)

The difference between your Shoes application and a web app is
that a web app is a client-server architecture. You can certainly use
Ruby and Sinatra for the server part, which responds to data requests,
but those requests come from a web client, in this case a browser. And
JavaScript is the language you use to program behavior in browsers.

That said, you could most simplistically use a meta-refresh tag in
an iframe on your page to display the changing data without any
user action. I certainly wouldn't try to refresh an entire page, even
a simple one, every second.

One way or another, you're going to have to learn how web clients
work, though. :-)

Good luck,
