After the huge success of the first six “Ruby Metaprogramming” batches, RubyLearning now announces the seventh batch from 26th Feb. 2011.
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.
US$ 19.95 per participant.
The course fee goes towards maintaining RubyLearning and helps provide quality content to you.
What Will I Learn?
The brief outline of this course is:
- Review the object model of Ruby itself:
- read-only variable self
- singleton class
- scope of variables
- Learn a lot of methods:
- class_eval (aka: module_eval)
- class_variables (Try it out: instance_variables)
- instance_variable_set (Try it out: instance_variable_get)
- const_get (Try it out: constants)
- Class.new (Try it out: Struct.new)
- binding (Try it out: lambda)
- send (Try it out: method)
- 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.
- Practice with assignments on how to write a tiny app with Ruby Metaprogramming techniques.
We will give you 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 will 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 teacher is 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”.
Here are some details on how the course works:
Once the course starts, you can login and start with the lessons any day and time and post your queries in the forum under the relevant lessons. Someone shall always be there to answer them. Just to set the expectations correctly, there is no real-time ‘webcasting’.
- The Mentors shall give you URL’s of pages and sometimes some extra notes; you need to read through. Read the pre-class reading material at a convenient time of your choice – the dates mentioned are just for your guideline. While reading, please make a note of all your doubts, queries, questions, clarifications, comments about the lesson and after you have completed all the pages, post these on the forum under the relevant lesson. There could be some questions that relate to something that has not been mentioned or discussed by the mentors thus far; you could post the same too. Please remember that with every post, do mention the operating system of your computer.
- The mentor shall highlight the important points that you need to remember for that day’s session.
- There could be exercises every day. Please do them.
- Participate in the forum for asking and answering questions or starting discussions. Share knowledge, and exchange ideas among yourselves during the course period. Participants are strongly encouraged to post technical questions, interesting articles, tools, sample programs or anything that is relevant to the class / lesson. Please do not post a simple "Thank you" note or "Hello" message to the forum. Please be aware that these messages are considered noises by people subscribed to the forum.
Outline of Work Expectations:
- Most of the days, you will have exercises to solve. These are there to help you assimilate whatever you have learned till then.
- Some days may have some extra assignments / food for thought articles / programs
- Above all, do take part in the relevant forums. Past participants will confirm that they learned the best by active participation.
