Meta programming means "programming your programming".

it will Change the way you program in your programming language.

• Transform your general-purpose language …
• Make it a domain-specific language.
• Program in a language designed for the problem you’re solving.

In Ruby :
----------

• Rubyists have been rediscovering metaprogramming.

• Ruby style and idioms are still changing and adapting.

• Rails leverages metaprogramming heavily.

• Ruby is a natural for metaprogramming.



What Makes Ruby Good for Metaprogramming:
------------------------------------------------------

• Dynamic and reflective
• Everything is open to change
• Blocks allow writing new control structures
• Add continuations to really get fancy
• Most declarations are executable statements
• Only slightly less malleable than Lisp (no macros)
• A fantastic syntax!
• Neutral and unobtrusive
• Enough to distinguish different kinds of constructs
• Not enough to complicate straightforward statements



Thanks
