What does metaprogramming in Ruby involve? or what is the goal of this book? I am new to Ruby so don't know much about it but is metaprogramming something to apply after learning the basics of Ruby as a language like applying design pattens after you learn to write code?

Yes: meta-programming requires a strong foundation in the basics.

If you're steeped in Java, then think about Java's reflection features. Reflection is not something that you learn on your first few days through the language - but when you're a bit more advanced, then you'll definitely want to know about reflection, and you'll probably use it fairly often. Metaprogramming is similar, but more advanced. So you should know the basics of Ruby before you start looking into it.

It is sorta covered in the JavaRanch Style Guide.
