The Druby Book

Completely updated and expanded from its Japanese version, with three new chapters written by Seki, this guide contains design concepts of the dRuby library, and step-by-step tutorial examples.

Ruby is famous for being easy to learn, but most users only scratch the surface of what it can do. While other books focus on Ruby's trendier features, The Book of Ruby reveals the secret inner workings of one of the world's most popular programming languages, teaching you 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. Rather than bog you down with a lot of theory, The Book of Ruby takes a hands-on approach and focuses on making you productive from day one. As you follow along, you’ll learn to: –Leverage Ruby's succinct and flexible syntax to maximize your productivity –Balance Ruby's functional, imperative, and object-oriented features –Write self-modifying programs using dynamic programming techniques –Create new fibers and threads to manage independent processes concurrently –Catch and recover from execution errors with robust exception handling –Develop powerful web applications with the Ruby on Rails framework Each chapter includes a "Digging Deeper" section that shows you how Ruby works under the hood, so you'll never be caught off guard by its deceptively simple scoping, multithreading features, or precedence rules. Whether you're new to programming or just new Ruby, The Book of Ruby is your guide to rapid, real-world software development with this unique and elegant language.

A guide to Ruby programming covers such topics as datatypes and objects, expressions, classes and modules, control structures, and the Ruby platform.

A New York Times bestseller and Oprah Book Club 2.0 selection, the epic, unforgettable story of a man determined to protect the woman he loves from the town desperate to destroy her. This beautiful and devastating debut heralds the arrival of a major new voice in fiction. Ephram Jennings has never forgotten the beautiful girl with the long braids running through the piney woods of Liberty, their small East Texas town. Young Ruby Bell, “the kind of pretty it hurt to look at,” has suffered beyond imagining, so as soon as she can, she flees suffocating Liberty for the bright pull of 1950s New York. Ruby quickly winds her way into the ripe center of the city—the darkened piano bars and hidden alleyways of the Village—all the while hoping for a glimpse of the red hair and green eyes of her mother. When a telegram from her cousin forces her to return home, thirty-year-old Ruby finds herself reliving the devastating violence of her girlhood. With the terrifying realization that she might not be strong enough to fight her way back out again, Ruby struggles to survive her memories of the town’s dark past. Meanwhile, Ephram must choose between loyalty to the sister who raised him and the chance for a life with the woman he has loved since he was a boy. Full of life, exquisitely written, and suffused with the pastoral beauty of the rural South, Ruby is a transcendent novel of passion and courage. This wondrous page-turner rushes through the red dust and gossip of Main Street, to the pit fire where men swill bootleg outside Bloom’s Juke, to Celia Jennings’s kitchen, where a cake is being made, yolk by yolk, that Ephram will use to try to begin again with Ruby. Utterly transfixing, with unforgettable characters, riveting suspense, and breathtaking, luminous prose, Ruby offers an unflinching portrait of man’s dark acts and the promise of the redemptive power of love. Ruby was a finalist for the PEN America Robert Bingham Debut Novel Award, a Barnes & Noble Discover Great New Writers selection, and an Indie Next Pick.

It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness. Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

Thirteen-year-old Ruby, a genius code-cracker and daring detective, gets an anonymous call setting a challenge that leads her to the headquarters of Spectrum, a highly secret anti-crime agency that needs her help to crack a code, but soon Ruby uncovers dastardly plans of the Fool's Gold Gang.

For more than a decade, Ruby developers have turned to The Ruby Way for reliable “how-to” guidance on effective Ruby programming. Now, Hal Fulton and André Arko have thoroughly updated this classic guide to cover new language enhancements and developers’ experiences through Ruby 2.1. The new edition illuminates Ruby 2.1 through 400+ examples, each answering the question: “How do I do this in Ruby?” For each example, they present both a task description and realistic technical constraints. Next, they walk step-by-step through presenting one good solution, offering detailed explanations to promote deeper understanding. Conveniently organized by topic, The Ruby Way, Third Edition makes it easier than ever to find the specific solution you want—and to write better code by reflecting Ruby’s unique philosophy and spirit.

The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. This book focuses squarely on object-oriented Ruby application design. Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

Seventeen-year-old Ruby Thomas, newly responsible for her two young nieces after a devastating tragedy, is determined to keep her family safe in the vast, swirling world of 1920s New York City. She’s got street smarts, boundless determination, and one unusual skill: the ability to throw a ball as hard as the greatest pitchers in a baseball-mad city. From Coney Island sideshows to the brand-new Yankee Stadium, Diamond Ruby chronicles the extraordinary life and times of a girl who rises from utter poverty to the kind of renown only the Roaring Twenties can bestow. But her fame comes with a price, and Ruby must escape a deadly web of conspiracy and threats from Prohibition rumrunners, the Ku Klux Klan, and the gangster underworld. Diamond Ruby “is the exciting tale of a forgotten piece of baseball’s heritage, a girl who could throw with the best of them. A real page-turner, based closely on a true story” (Kevin Baker, author of Strivers Row).
