1. require 'whatever.rb' -or- load 'whatever.rb'
2. runtime is basicly the ruby distribution - the interpreter and the
libs. on windows it probably means the one-click installer
(http://rubyforge.org/projects/rub...)
3. don't know IIS, but I'd that by having IIS run them ;-) Or, using
intermediate ruby webserver(s) like mongrel or webrick. Or, if it is
possible, but using FCGI/FastCGI/SCGI (plain old CGI is too slow most
of the time).

If you want to include it once (a library, perhaps), use require, as in

require 'somefile' # will try to load somefile.rb or a .dll, .so, .o and so on

Or if you want to run a file as many times you wish, use load:

load 'somefile'

Whats server? There's mod_ruby for Apache.

If you're using Rails, see http://wiki.rubyonrails.org/rails/pages/How...

I'm only addressing #3,#4 because the the others have been well answered.


Here is a blog posting on how to use ruby in classic asp pages. I
suggest it because if you're a win32 programmer, it's the easiest way to
get your foot in the door with ruby, before trying rhtml or rails.
Here's the link:
http://mogrify.homelinux.org/2006/06/02/using-ruby-in-...

As for an ide, a *free* alternative is:

If you'd like a personal recommendation to narrow down this list, I like
RadRails better than any other Ruby IDE I've tried. The ones I've tried
are Komodo, Eclipse + RDT, FreeRIDE, SciTE and Arachno Ruby.

require 'uri'
uri = URI.parse( 'http://del.ic... )
puts uri.host

Unfortunately you can't get more fine grained than that without
asking DNS. Why? Because ruby can't know all the top-level domains.

Look at URI it it does something for you. Anyway, the question is more
complicated than it seems (take 4 level domains for example).
Basically url.split('.')[1..-1] could make it.

Well, no it couldn't ;)

Makes perfect sense,
does anyone know how to ask DNS for a url then?
