Hey ...
I'm taking my first steps with Ruby. I have ruby-mode loaded and
working. I also have run-ruby, but we'll forget about that for the
moment.
I have a working script that I want to "compile" and run while in ruby-
mode. I grok how to compile it - no worries there. The script asks for
input from the user. That's what I don't know how to do! Is there a
way to input a value while in the 'compilation' process? TIA...

M-x compile doesn't allow for interactive use, so you don't want that.
I use M-x shell for almost all these scenarios (and nearly all other shell use, really). You can also look at my autotest.el if you're wanting to make something shell-like but more tweaked out for your use. You can find that on emacswiki.

Have you looked into ruby-compilation.el? The version on emacswiki.org is
old, but you can either install it via ELPA, or from
rinari/util at master · eschulte/rinari · GitHub directly. You can then
M-x ruby-compilation-this-buffer and it will execute your script in a
compilation buffer. You can input data in the compilation window, but note
that you might find that RET doesn't do the job because it's been shadowed
by a different mode. If this happens to you, you will need to rebind
comint-send-input.

OK!

Much obliged! Thanks ...

There are a number of other good packages for Ruby in ELPA as well. I think
you might have to manually install mode-compile.el, IIRC. ELPA doesn't seem
to supply that, but I think this package depends on it. See
http://www.emacswiki.org/emacs/ModeCompile

I installed ruby-compilation.el from ELPA, after installing support
for the latter. I fired some Ruby code, and it works! but ...
Your were right ...
If this happens to you, you will need to rebind comint-send-input.
What do you mean by "rebind comint-send-input"?
The way I'm doing it is:
after I'm done inputting data into the program, I do a M-x comint-send-
input, instead of a `cr'. Is that correct?
It executes OK, and the program output is correct, but I may be taking
"the long way around". 
Thanks for your input.

This gives you a couple advantages over installing it from ELPA. C-x t will
invoke ruby-compilation-this-buffer whenever you are in ruby-mode, and now
hitting return/enter will invoke comint-send-input in the compilation
buffer.
By the way, you might find the following useful for learning and programming
Ruby in Emacs. See http://www.emacswiki.org/emacs/FlymakeRuby for automated
syntax checking. Also, install the ruby-debug (or ruby-debug19 for Ruby
1.9) gem for Ruby debugging. Take a look at
Debugging with rdebug from GNU Emacs for Emacs
integration of this debugger.

It'd be a lot more maintainable if you didn't modify the file and instead added the define-key to your .emacs:
(define-key ruby-compilation-minor-mode-map [return] 'comint-send-input)

OK! Followed your instructions to the letter ...
and hacked my .emacs for the key map stuff, as per Ryans advice ...
NO joy!
In *Messages* buffer, I get:
"compilation-next-error: No error here"
after being asked for the required input.
The script does work BTW. Any ideas?

Thanks a lot for all those links. They surely will be useful to me.

Yes, that's definitely better than my crude hack.

It sounds like return is still bound to compile-goto-error. Did you restart
Emacs after modifying your .emacs file? You might want to check your
keybindings in the compilation buffer. Get it in focus and hit C-h b, and a
new window will be created with your current keybindings. Look under
ruby-compilation-minor-mode in the keybinding buffer and see if there is an
entry for key <return> and binding comint-send-input.

Everything is now working great! I had simply re-loaded my .emacs file
thinking that doing so would be enough. Once I re-started "emacs",
well things couldn't be much better! Thanks a bunch.
