Scripting and automation tasks often need to extract particular portions of text from input data or modify them from one format to another.

This book will help you learn Ruby Regular Expressions, a mini-programming language for all sorts of text processing needs.

The book heavily leans on examples to present features of regular expressions one by one. It is recommended that you manually type each example and experiment with them. Make an effort to understand the sample input as well as the solution presented and check if the output changes (or not!) when you alter some part of the input and the command. As an analogy, consider learning to drive a car — no matter how much you read about them or listen to explanations, you'd need practical experience to become proficient.

Exercises are included to test your understanding. Reference solutions are also provided.

Prerequisites:

You should be familiar with programming basics. You should also have a working knowledge of Ruby syntax and features like string formats, string and Enumerable methods.

You are also expected to get comfortable with reading documentation, searching online, visiting external links provided for further reading, tinkering with illustrated examples, asking for help when you are stuck and so on. In other words, be proactive and curious instead of just consuming the content passively.

If you have prior experience with a programming language, but new to Ruby, check out the official quickstart guide. The examples presented here have been tested with Ruby version 3.3.0 and includes features not available in earlier versions.
