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.
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.

The regular expression (regex) has been around for over 60 years and it's still poorly understood-and incorrectly used-by most developers. Why? Mainly because regexes are rarely taught to developers; they're just left to "pick them up" as they go along. This means most developers don't know what regexes do, how they work, how to use them, how to optimize them, or how to maintain them. In this course, regex expert Damian Conway changes this equation. He explains regexes in detail and shows you the power of these amazing and efficient tools. Bonus: learners will receive a 12-page cheat-sheet for download that shows all major regex constructs across six dialects.

Learn how to think about regexes and stop being confused, confounded, or terrified by them
Master what each regex component does and the problems it can solve
Discover the pitfalls of each regex component and learn how to avoid these mistakes
Learn why regexes run slowly and how to optimize them (sometimes by orders of magnitude)
Explore ways to decompose and refactor a regex
Gain experience building complex regexes that work
