Ruby Metaprogramming

[Ari Brown]

Are there any suggested resources on learning the art of Ruby
metaprogramming?

yea, it's a short message... But a good one nonetheless

I think this old quiz is a great first step:

I can buy Ruby for Rails at my local bookstore, but it costs a bunch.
Is it really so good for me to spend $50? I don't exactly have a job
(too young), so take that into account...


Thanks,

English is like a pseudo-random number generator - there are a
bajillion rules to it, but nobody cares.

I don't know if this is enough of a difference, but it's only $30 at
Amazon, with free shipping:

I can't really answer the question about whether R4R is worth $50, it
depends what $50 is worth to you. I have a copy of it here on my
shelf, I thought it was worth it.

In terms of cheap alternatives, use the Ruby Quiz, and Google, and blogs.

Ola Bini has a good overview on metaprogramming:

http://ola-bini.blogspot.com/2006/09/ruby-metaprogramming-techniques.html

Glenn Vanderburg has a good set of presentation slides:

http://www.vanderburg.org/Speaking/Stuff/oscon05.pdf

I found this stuff just by googling "ruby metaprogramming." There's
plenty of good stuff out there.

Another resource that I haven't noticed mentioned yet is _why's Dwemthy's
Array stuff:

and

Also Jamis wrote about it indirectly in his post on DSLs:

metakoans right? Yes and the work of Ara in general, look at Prototype e.g.
and then there is Eigenclass of Mauricio and Why's site (google Why
the Lucky Stiff) and sorry if I forgot some ressources.

And I think a PDF versions is also available from the Manning site.

And I think a PDF versions is also available from the Manning site.

It is, for $22.50, about half the cost of the printed version.

Thanks! I'm going to start a little page of MetaProgramming links
(either generic languages or ruby-specific),

so if anyone has any link or book they'd like to share, I'd be glad
to put it up.

Programming books are expensive, especially when you get one that
turns out to be no good or at least no good for you.
But luckily, Ruby (and Rails) books are always good. I haven't found
a bad one yet.
When they're good, they're worth the price, because you'll keep
looking back to them for information.

Just to be entirely capricious, there's a totally different way to
take the words "Ruby metaprogramming," which concerns using IRB with
lots of enhancements. A lot of popular Ruby apps have interactive
shells, Ruby itself has one, and if you do a lot in the interactive
shells, you're working in an environment defined by Ruby code. You can
add features to that environment by adding new Ruby code to the Ruby
code which already defines it. So programming your programming
environment in Ruby is one highly productive way to deliberately
misuse the term "Ruby metaprogramming."
