Overview of this book

Are you a PHP developer looking to take your first steps into the world of Ruby development? From PHP to Ruby on Rails will help you leverage your existing knowledge to gain expertise in Ruby on Rails. With a focus on bridging the gap between PHP and Ruby, this guide will help you develop the Ruby mindset, set up your local environment, grasp the syntax, master scripting, explore popular Ruby frameworks, and find out about libraries and gems. This book offers a unique take on Ruby from the perspective of a seasoned PHP developer who initially refused to learn other technologies, but never looked back after taking the leap. As such, it teaches with a language-agnostic approach that will help you feel at home in any programming language without learning everything from scratch. This approach will help you avoid common mistakes such as writing Ruby as if it were PHP and increase your understanding of the programming ecosystem as a whole. By the end of this book, you'll have gained a solid understanding of Ruby, its ecosystem, and how it compares to PHP, enabling you to build robust and scalable applications using Ruby on Rails.

Debugging Ruby

Just like with any other significant programming language, Ruby has a number of tools to help us analyze, fix, and improve our code. According to a software architect I encountered many years ago, the disparity between a programmer who possesses debugging skills and one who lacks them equates to the distinction between a junior programmer and a senior programmer. By using the right tools to debug our code, we can both improve our code and improve our understanding of how the language is interpreted, which in the long run, is beneficial to our path as developers. Let’s take a look at the tools that come with Ruby out of the box, as well as the gems that the Ruby community has developed to debug our code.

With debugging in mind, in this chapter, we will cover the following topics:

  • Debugging functions in Ruby versus PHP
  • Gems for debugging
  • Understanding Interactive Ruby (IRB)s usefulness
