Presentation: The Beauty of Ruby

Bookmarks

Jul 05, 2007 less than one minute

As Edd Dumbill wrote, "the subtle elegance of the Ruby idiom is a slowly appreciated and highly satisfying flavour." It's true that some of the best things about Ruby aren't obvious to newcomers. In this talk Glenn Vanderburg demonstrates some of the subtle beauty that experienced Rubyists know and love.

Watch The Beauty of Ruby (54 min)

The beauty points Glenn looks at are:
  • Blocks
  • Rich Yet Flexible Syntax
  • Mixins
  • Lisp-Y-ness
  • Generalized Matching & Ruby's powerful case statement
  • Classes and objects are "open" can be modified at runtime
  • Metaprogramming features
Finally, looking at tradeoffs in the language's design, Glenn concludes that "We Rubyists lose some things due to Matz’ choices., but what we gain seems to make up for it. - Thanks Matz!"

    Ruby is a great language. Rubyist should definitely not ignore some even more elegant languages like Smalltalk and LISP.

  • Talk was incorrect regarding arrays of regexp objects in perl

    by Josh ben Jore,

    Your message is awaiting moderation. Thank you for participating in the discussion.

    Perl has had a regexp object since 5.6 was released in 2000. I don't know of any operating systems that still ship with an older version. The speaker should have done his homework on this before spending what seemed like five minutes larking about how this feature was lacking.

    We've had this seven years now. Please catch up.

  • Don't talk about Perl if you don't know it

    by brian d foy,

    Your message is awaiting moderation. Thank you for participating in the discussion.

    Ruby is certainly a nice language and I like it. However, you shouldn't
    use your ignornace if Perl to support Ruby:

    * Perl sigils do not denote type: they denote context. $scalar is a
    scalar, but $array[0] works with an array, and $hash{foo} works with a
    hash. @array[0,1] works with an array, but @hash{'foo', 'bar'}. It's
    not type, what you're doing with it. You can read more about that in
    Learning Perl.

    * Perl regular expressions aren't operators: the match operator, m//, is an
    operator, but that's not the thing that's the pattern. The stuff
    inside the match operator is the pattern, but the pattern is not the
    match operator. You can create a regular expression without the match
    operator with the qr() quoting mechanism.

    You'll eventually find that Ruby, if it gets as popular as Perl, will be treated as poorly as Perl as newbies learn by hit-and-miss. Newbies will invent their own systems to explain the portions of Ruby that they know and that they think they understand. Just wait :)

    Tnx!
    I really like to learn from these Ruby presentations since I am unable to be at the conferences for now.
