Is there an easy way to save the contents of an object in ruby?

This is hard to google, so I am posting it up. I just need a general
idea (if anyoen has it), you don't have to spell it out for me.

As a further aside to saving with yaml, yet another fantastic little
goody that RoR provides is the method .to_yaml() ..

ilan@iberci-pc:~/rails$ script/console
Loading development environment.
>> "sample".to_yaml
=> "--- sample\n"

You don't need RoR for that. Merely including yaml will give objects
the to_yaml method:

irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> puts({"one"=>1,"two"=>2,"three"=>3}.to_yaml)
---
three: 3
two: 2
one: 1
=> nil

I posted an article/tutorial on marshalling objects and saving them to
files last night,
you may want to throw a quick look at it as it sounds applicable to your
question...

Use YAML you can store/load the content of a Ruby object without any
difficulty.

Please visit YAML.rb at http://yaml4r.source...
The codebook is of great use to give you what is going on:

The built-in Marshal class is designed for this very thing, and
anecdotal evidence says it's faster than YAML. YAML has the advantage
of being readable to the naked eye, however. Here's a good discussion
on Marshal vs. YAML:
