Master the Ruby programming language—to write more powerful libraries or improve your Rails applications—by learning advanced techniques in this hands-on course for experienced Ruby developers.
You'll come away from this course feeling like a Ruby Master. You'll not just know Ruby in depth, you'll also understand why things are the way they are. You'll have moved beyond the basic toolbox of the average Ruby developer—you'll be able to exploit the libraries and constructs the true pros use to make their code powerful, compact, and fun to work with.
Learn how to:
- Gain best practices and Advanced Ruby Programming Techniques.
- Solve real problems using Ruby like a pro.

"The course material was great and comprehensive. I walked away with so much new knowledge and even better, a huge list of things to look into and learn."David Naffis on 25th Apr 2014
Object Oriented Design in a Dynamic Language
Ruby is different than the languages you're used to. If you're still using the techniques that work with those languages, you're not exploiting the power of Ruby, and you're writing more code than you need.
- Reuse mechanisms unique to Ruby and dynamic languages
- Modules and mixins
- Composition and delegation
- Runtime class extensions
The Ruby Object Model
Understand the underlying object model in Ruby, and everything falls into place. By truly understanding the Ruby object model, you'll be a better Ruby programmer.
- The internals of objects and classes
- How classes really aren't anything special
- Why self is important, and how it changes
- How methods are called dynamically
Metaprogramming lets you program more expressively. It makes your code easier to write and easier to maintain and extend. You'll learn how to apply Ruby metaprogramming techniques to your advantage.
- How blocks act as closures, and why that's vital to metaprogramming
- Creating methods on the fly using define_method
- Evaluating code at runtime using eval, instanceeval, and classeval, and when to use one versus the other
- Techniques for runtime class and object extension
- Practical uses of metaprogramming for writing internal Domain Specific Languages (DSLs)
Advanced Programming Techniques
- Blocks, Procs, and closures in depth
- Meta-classes and the meta-object protocol
- Using reflection to discover and inspect classes, inheritance hierarchies, defined methods, and instantiated objects at runtime
Ruby hook methods are a way for your application to hook itself into the execution of the Ruby interpreter. Using hook methods is crucial for some kinds of metaprogramming, and they can make your code more flexible.
- Mixing methods into classes using included
- Decoupling code using inherited to keep track of subclasses
- Using method_missing to create magic methods
- Applying const_missing in both global and localized situations
- Practical uses for hook methods
New Ruby 2 Features
As a Ruby programmer, you'll want to stay on top of all the new syntax and language features.
- Overview of the new classes and libraries
- Major changes to String
- Keyword arguments
- Lazy enumerators
- More powerful regular expressions
- Multi-nationalization of code and data
- Fibers and threads
- And more!
We may know all the secrets of coding Ruby, but we still need to make it work in the real world. - Performance - Debugging and Profiling - Practical tips, tricks, and techniques
In addition to the prepared topics, you'll have time to ask questions and spark discussions with other experienced Ruby programmers.
Intermediate Ruby Programmers (1 to 2 years experience).
This course will be a good fit for you if:
- You have a good working knowledge of the Ruby language, but you want to take it to the next level.
- You've tried what you consider to be advanced features in Ruby, but you want to understand when and how experts use those features.
- You've taken an introductory Ruby Programming course or you're familiar with the fundamental of Ruby Programming.
Delegates should have basic Ruby programming skills before attending this course. If you do not have these skills please contact us to discuss booking an introductory Ruby training course.
