Download or read book Eloquent Ruby written by Russ Olsen and published by Addison-Wesley Professional. This book was released on 2011-02-07 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book DSLs in Action written by Debasish Ghosh and published by Simon and Schuster. This book was released on 2010-11-30 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Your success—and sanity—are closer at hand when you work at a higher level of abstraction, allowing your attention to be on the business problem rather than the details of the programming platform. Domain Specific Languages—"little languages" implemented on top of conventional programming languages—give you a way to do this because they model the domain of your business problem. DSLs in Action introduces the concepts and definitions a developer needs to build high-quality domain specific languages. It provides a solid foundation to the usage as well as implementation aspects of a DSL, focusing on the necessity of applications speaking the language of the domain. After reading this book, a programmer will be able to design APIs that make better domain models. For experienced developers, the book addresses the intricacies of domain language design without the pain of writing parsers by hand. The book discusses DSL usage and implementations in the real world based on a suite of JVM languages like Java, Ruby, Scala, and Groovy. It contains code snippets that implement real world DSL designs and discusses the pros and cons of each implementation. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book. What's Inside Tested, real-world examples How to find the right level of abstraction Using language features to build internal DSLs Designing parser/combinator-based little languages

Book excerpt: NEW YORK TIMES BESTSELLER • CBC KIDS’ BOOK CHOICE AWARD WINNER Civil rights icon Ruby Bridges—who, at the age of six, was the first black child to integrate into an all-white elementary school in New Orleans—inspires readers and calls for action in this moving letter. Her elegant, memorable gift book is especially uplifting in the wake of Kamala Harris making US history as the first female, first Black, and first South Asian vice president–elect. Written as a letter from civil rights activist and icon Ruby Bridges to the reader, This Is Your Time is both a recounting of Ruby’s experience as a child who had to be escorted to class by federal marshals when she was chosen to be one of the first black students to integrate into New Orleans’ all-white public school system and an appeal to generations to come to effect change. This beautifully designed volume features photographs from the 1960s and from today, as well as stunning jacket art from The Problem We All Live With, the 1964 painting by Norman Rockwell depicting Ruby’s walk to school. Ruby’s honest and impassioned words, imbued with love and grace, serve as a moving reminder that “what can inspire tomorrow often lies in our past.” This Is Your Time will electrify people of all ages as the struggle for liberty and justice for all continues and the powerful legacy of Ruby Bridges endures.
