دانلود کتاب برنامه‌نویسی Ruby

This book will give you a foundation in Ruby. It’s organized to first provide the fundamental building blocks of the language; then adds a study of higher-order classes and modules; and finishes by teaching you how to apply what you’ve learned through advanced Ruby techniques and program design. The Well-Grounded Rubyist, Fourth Edition is written for the reader who’s done some programming and perhaps even some Ruby and wants to learn more about the Ruby language. In reading this book, you’re going on a journey with us to learn not only specific techniques but also the design principles and richness of the language. We love Ruby and we hope to impart not just the specifics of the language we love but also why we love it. The goal of the chapter is to bootstrap you into the study of Ruby with enough knowledge and skill to proceed comfortably into what lies beyond. We’ll look at how Ruby works: what you do when you write a program, how you get Ruby to run your program, and how you split a program into more than one file. You’ll learn several of the switches that alter how the Ruby interpreter (the program with the name ruby, to which you feed your program files for execution) acts, as well as how to use some important auxiliary tools designed to make your life as a Rubyist easier and more productive.
