Ruby and URL Variables

I’m quite new to Ruby and am wondering if there is a way to access what
I called “URL variables” (not sure if that’s the proper name.) They were
essentially GET variables, and PHP made it very easy to access with a
global called $_GET.

Is there an equivalent for Ruby? I’m trying to avoid using Rails, I
don’t like it much.

For more clarification, if somebody visits a file called “test.rb” in
their web browser with the full URL “test.rb?foo=bar,” how could I have
the app print “bar,” or more specifically, the value of foo.

Those are called GET-Parameters :).

As Ruby is not built with web development in mind, it does not have
such a thing.

But parameters are accessible through the CGI-Library. You can
find an introduction here: (it is a bit dated, but it mostly fits)

There are other nice web frameworks in Ruby - try one of those.

Thanks very much for that link, I’ve got it working now. :slight_smile:
