Debugging Ruby Programs with Pry

Every developer spends more time debugging than writing new code, yet many rely on simple print statements to find errors. This text-based course introduces you to the power of terminal-based debugging in Ruby, showing you how to inspect running code and fix bugs with precision. You will move from guesswork to systematic troubleshooting using industry-standard console tools. By the end of this course, you will be able to pause execution, inspect the state of your application, and resolve complex issues confidently inside your terminal. What you'll learn: Understand foundational debugging concepts and how interactive consoles differ from static code analysis; Configure the Pry gem and integrate it into any Ruby script or application; Set breakpoints to pause execution at critical moments in your code; Inspect local variables, instance state, and call stacks in real time; Practice modern debugging workflows to isolate and fix logic errors quickly; Explore advanced terminal commands to navigate through complex loops and conditional blocks. The course begins with core debugging terminology and basic console setup before moving step-by-step through practical debugging scenarios. This course is designed for beginner Ruby developers who want to improve their troubleshooting skills. No prior debugging experience is required, though a basic understanding of Ruby syntax is recommended. Start reading today and master the art of terminal-based debugging.
