Ruby can be your standard global-function type of language. You don't
have to define objects (though all the 'primitives' are still objects,
you don't have to think about them as such). But if you want to
over-ride the default + method for integers, you can (not that you would
to).
The way it works is that it will just starting executing all the method
calls it sees, like Perl.
And regardless, OOP isn't that hard, I can't understand why someone
wouldn't want to at least take advantage of some its syntax. I guess
thats kind of elitists of me.

How disappointing. Perl certainly doesn't limit it's usefullness only to the
Object-oriented elite. IMHO, that makes Perl rock even more than Ruby.
Oh, and if you like some of that cool Ruby goodness, well, you can always just
install Simon Cozens' Rubyisms.pm module from CPAN.
See http://search.cpan.org/~simon/rubyisms-1.0/
And from http://search.cpan.org/src/SIMON/rubyisms-1.0/README we see...
NAME
rubyisms - Steal some features from Ruby
SYNOPSIS
package Foo;
use rubyisms;
sub initialize { # We inherit a new from class Class
self->{foo} = "bar"; # And we have a receiver, self
__private_stuff(1,2,3,4);
}
sub __private_stuff {
self->{things} = [ @_ ]; # self is still around
self->another_method;
}
sub my_method {
if ($interesting) { ... }
else { super } # Dispatch to superclass
}
sub array_iterator (&@) {
yield() for @_;
}
array_iterator { print $_[0], "\n" } ("Hello", "World");
..
Well, Ruby steals plenty of features from Perl, so I guess thats fair.
Though all those @'s, $'s and _'s make me cringe a bit (Ruby has some of
that for Regex expressions, but actually has a module called English to
give them logical names). As its description says, its just to steal
some features from ruby (mainly the yield() call as far as I can tell,
don't know enough Perl to see what else is new).
Its one thing to have a yield call, its another when all the standard
libraries are built around exploiting it. Many languages have ways of
passing blocks of code to other methods, Ruby is the first I've seen
actually taking advantage of it throughout the standard libraries.
Hehe. Perl *rocks*. Ruby just *wishes* it could rock this hard. And wait 'til
Parrot/Ponie/Perl6 is out.
Oh, and Simon implemented *ALL* of the above in a mere 90 lines of Perl code.
If you _really_ want to learn about OO and even more ways in which Perl makes OO
easy where other languages "hit the wall" (e.g. closures and multiple
inheritance in Java), then you should get Damian Conway's book Object-Oriented
Perl (ISBN 188491 - http://www.manning.com/Conway/ ). Unbelievably lucid,
and it's no mistake that he used Perl to demonstrate these OO concepts.
The "eat-your-brain" explanation of Perl's "tie" feature is excellent.
He discusses multiple inheritance, data inheritance vs. interface inheritance,
closures, functions as objects, truly private data members, inheritance by
composition, and explores some of the dark corners of Perl's "tie" facility,
re-blessing objects, and more.

Really I don't know enough Perl to be able make a comparison. However,
my experience with 'oh yea, Object Oriented looks nice, let's add that'
type of languages (which it sounds like Perl is from its history) is
from PHP. I quite like PHP, but OO design is hardly ever used in the
various libraries. So there are tons of global functions. With Ruby
theres only a handful of global functions, they're all methods from the
object named Kernel (so unlike other languages, they're aren't really
special keywords, part of what makes Ruby so dynamic).
Mercury now has Ruby 1.8.1 (the newest) installed on it. You can use the
ruby shell irb to play around with it easily. Send me a message if
anyone wants other ruby libraries installed, currently it just has the
various standard and the mysql libraries. Kronos has the Debian Woody
package of Ruby, so its version 1.6.

sorry last mail got messed up, no idea why... Hi folks, If you are a computer linguistic geek or simply a real programmer at heart (which, I think, is the very reason why you are on this mailing list) you should come to the TSLUG meeting tonight. Ian?s mentioned it already, but here again: he and I are going to spread the word why Ruby rocks. Ruby is an awesome programming language entirely built upon the concept of objects. While I just was astounded and exited when learning Perl (because of its many features), Ruby just exceeding any of my expectations when it comes to syntax and oo concepts. So you should come to the Meeting tonight to make up your own mind about me (and Ian) being simply just freaks or Ruby just being a language that rocks. I thing Ian thinks similar on that issue, after all he is the object oriented fan.? alex - To get off this list, send email to [EMAIL PROTECTED] with Subject: unsubscribe -

You must be thinking of Ark-as-in-Noah Linux. This is Arch-as-in-Saint-Louis Linux. Arch is more or less from scratch, Ark is based on Redhat I think. The two distros probably started at around the same time so the name conflict wasn't apparent. On that note, the new version of Mozilla Firebird is named Firefox. While Firefox is a cooler name and without the conflict with the database, I think its getting a little ridiculious that they change their name so often. And I'm pretty sure its eventually going to be called "Mozilla" regardless. [EMAIL PROTECTED] wrote: Osnews has a very glowing review of Arch Linux.

The installfest is on Feb 21 15:00 in VH1010.
Osnews has a very glowing review of Arch Linux.
http://www.osnews.com/story.php?news_id=5971 It looks interesting. It uses
just .tar.gz packages but has its own system ("pacman") of solving
dependencies and such that looks easy like Debian and Gentoo, without the
out-of-date software and long compile times respectively. I think it might
be a good distro to look into for people wanting something like Debian
that is up-to-date. Most of the Debian-based distros that feature
up-to-date packages like Libranet don't have free downloads.
