Effective Ruby will help experienced Ruby programmers harness all of Ruby's power to write more robust, efficient, maintainable, and well-performing code. Utilizing the concise, scenario-driven style pioneered in Scott Meyers's best-selling Effective C++, Peter Jones brings together 50 Ruby best practices, tips, shortcuts, and realistic code examples from expert programmers. Through realistic examples, Jones uncovers little-known Ruby quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. You'll learn how to choose the most efficient and effective way to accomplish key tasks when multiple options exist, and how to write code that's easier to understand, maintain, and improve. Drawing on his deep understanding of Ruby's capabilities, Jones offers practical advice for each major area of Ruby development, including: * Modules, classes, and objects * Collections * Exceptions * Metaprogramming * Testing * Memory and object management Each section contains specific, actionable guidelines organized into items, each with carefully worded advice supported by detailed technical arguments and illuminating examples.Using Effective Ruby, developers can systematically improve their code: not by blindly following rules, but by gaining a deep understanding of the technical reasons why those rules of thumb make sense.
