Ruby Metaprogramming Course – Learn to Think in Ruby

by Satish Talim on September 14, 2010

After the huge success of the first three “Ruby Metaprogramming” batches, RubyLearning now announces the fourth official batch from 23rd Oct. 2010.

What’s Ruby Metaprogramming?

Paolo Perrotta has this to say:

As a Ruby programmer, you already know how much fun it is. Now see how to unleash its power, digging under the surface and exploring the language’s most advanced features: a collection of techniques and tricks known as metaprogramming. Once the domain of expert Rubyists, metaprogramming is now accessible to programmers of all levels – from beginner to expert.

Paolo goes on to say the following in a recent interview:

I realized that metaprogramming sits at the very heart of the language, and when you understand metaprogramming, that’s the moment you start “thinking in Ruby”.

Who’s It For?

Anyone who has some background in Core Ruby can make the most out of this course.

Dates

The course starts on 23rd Oct. 2010 and runs for 2 weeks. You first need to register on the site and then enroll into the course.

What Will I Learn?

The brief outline of this course is:

First Week:

  • Review the object model of Ruby itself:
    • read-only variable self
    • singleton class
    • scope of variables
  • Learn a lot of methods:
    • eval
    • instance_eval
    • class_eval (aka: module_eval)
    • class_variable_set
    • class_variable_get
    • class_variables (Try it out: instance_variables)
    • instance_variable_set (Try it out: instance_variable_get)
    • define_method
    • const_set
    • const_get (Try it out: constants)
    • Class.new (Try it out: Struct.new)
    • binding (Try it out: lambda)
    • send (Try it out: method)
    • remove_method
    • undef_method
    • method_missing
    • include
    • extend
    • included
    • extended
  • Do the following five exercises and discuss them in the forum.
    • Exercise 1: Get the values from outside the class.
    • Exercise 2: Add your code to display ‘I like metaprogramming!’
    • Exercise 3: Show lots of ways to define singleton method.
    • Exercise 4: Glance inside Ruby with binding method.
    • Exercise 5: Define a class without class and def.

Second Week:

  • Practice with assignments on how to write a tiny app with Ruby Metaprogramming techniques. The assignments are being prepared.

For Newbies

We will provide you with short study notes. You can learn the following and discuss the same in the course forum.

  • Instance variables, Methods and Classes
  • Calling a method
  • Useful methods in Ruby Metaprogramming
  • Ruby Blocks and Bindings
  • Solved Problems (two examples)

For Intermediate Participants

We willl open the discussion forum with some advanced topics like “Compare Ruby Callable Objects” (Yugui’s blog posts) etc.

Who is conducting this course?

The course is conducted by Satoshi Asakawa from Japan with 24×7 help from the mentors at RubyLearning. Satoshi is a Japanese Ruby enthusiast.

So hurry, registrations have started.

By the end of the course, and to reiterate what Paolo Perrotta said, you will understand metaprogramming and that’s the moment you will start “thinking in Ruby”.

Hi I am trying to choose between the Ruby 101 course and this one. I have quite a bit of experience with Rails, but I feel as though I don’t have a good grasp on Rails itself, for example, looking at the ruby challenges I don’t even know where to start. I have a decent grasp on using Ruby on Rails, but when it comes to using Ruby on its own I’m feel lost. Any suggestions?

Most dudes I know started directly with Rails and then realized down the line that their Ruby needs to be good too! Around 20% of the participants on RubyLearning so far, have been from this category. If time permits please do undergo the 2 month Core Ruby course followed by the metaprogramming one.

Thanks. I’ll definitely go ahead with that.
