Regular Expressions Machinery: The Illustrated Guide

This book is written for those who want to deeply understand regular expressions. Maybe you’ve come across them in programming languages or tools, but never really understood how they work under the hood. The book presents complex concepts in a simple and visual way, with clear examples and practical applications. Whether you are a programmer, data analyst, or just want to get better at text processing, this book will take your knowledge to the next level.

The goal of the book is to give you a deep understanding of regular expressions so that you can use them with confidence and efficiency in your work. We begin by looking at the theoretical basis of regular expressions: finite automata. Then, we go through the only two operations and the only function needed to create regular expressions. We also thoroughly explore all basic and advanced features of modern regular expressions, and some of the most common pitfalls. Finally, we examine the concept of test-driven development (TDD) and how you can leverage it to write regexes that are correct and easy to maintain in your production code.
