20 Recommended Free Books to Learn about Ruby
Last Updated on October 25, 2024
Ruby is a general purpose, scripting, structured, flexible, fully object-oriented programming language with a focus on simplicity and productivity. Ruby is a very conservative language. It’s equipped with very carefully chosen features that have been fully tested.
Ruby possesses a high portability running a large number of platforms including Linux, Windows, Mac OS X, Cygwin, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, Tru64 UNIX, and HP-UX. The TIOBE Programming Community index currently ranks Ruby in 13th place.
Ruby’s popularity was enhanced by the Ruby on Rails framework, a full-stack web framework which has been used to create many popular applications including Basecamp, GitHub, Shopify, Airbnb, Twitch, SoundCloud, Hulu, Zendesk, Square, and Highrise.
I recommend 20 free books which will teach you the basics of Ruby. Many of the books are open source. All of them can be read without requiring payment although some of them are available to purchase in paperback or electronic versions. Never underestimate the benefits of buying a printed copy of a programming book, as well as compensating the author for his work.
1. Learn Ruby the Hard Way by Zed A. Shaw
The full title of the book Learn Ruby the Hard Way: A Simple and Idiomatic Introduction to the Imaginative World Of Computational Thinking with Code is a bit of a mouthful.
Don’t be misled by the title of the book. The book is designed for beginners to programming that are looking to learn Ruby. It shows you at a gentle pace how to build basic skills in Ruby programming. It’s a very good introductory text.
Now in its 3rd edition, Learn Ruby the Hard Way Learn Ruby the Hard Way is available to read for free. The video lectures are not included. You can also purchase paper versions of the book.
2. Book of Ruby – A Hands-on Guide for the Adventurous by Huw Collingbourne
[画像:The-Book-of-Ruby]The Book of Ruby describes the secret inner workings of Ruby, helping you learn to write clear, maintainable code.
You’ll start with the basics — types, data structures, and control flows—and progress to advanced features like blocks, mixins, metaclasses, and beyond.
The Book of Ruby takes a hands-on approach. It contains 425 pages in 20 chapters. It is provided in the form of a PDF.
The author of the book is a co-developer of the Ruby In Steel IDE.
3. Ruby Best Practices by Gregory T Brown
Ruby Best Practices aims to help Ruby developers from a wide range of skill levels improve their fundamental understanding of the language via exposure to the common practices and idioms that many seasoned Rubyists take for granted. With a strong emphasis on exploring real codebases, and an understanding that beautiful solutions depend heavily on context, this book lays out a clear road map to Ruby mastery for those who wish to pursue it.
Written by the developer of the Ruby project Prawn, this concise book explains how to design beautiful APIs and domain-specific languages with Ruby, as well as how to work with functional programming ideas and techniques that can simplify your code and make you more productive. You’ll learn how to write code that’s readable, expressive, and much more.
The book’s website has been down for years. But a PDF copy is available. Definitely one to download.
4. Ruby Hacking Guide by Aoki-san
[画像:Ruby Hacking Guide]Ruby Hacking Guide is a book intended for advanced programmers. The book explains how the Ruby 1.7.x-1.8.x interpreter (the official C implementation of the Ruby language) works internally.
This book was originally written in Japanese, and has been translated into English. Some chapters are previews.
5. I Love Ruby by A.K. Karthikeyan
I love Ruby: Get started with the greatest programming language made for humans is suitable for anyone interested in learning Ruby.
Its examples are designed for Ruby 2.5.
You can grab this book from https://i-love-ruby.gitlab.io/. And the complete book with source code is available from the author’s GitLab repository. There’s also paperback and Kindle version available to purchase.
