In 1994, Design Patterns changed the landscape of object-oriented development by introducing classic solutions to recurring design problems. In 1999, Refactoring revolutionized design by introducing an effective process for improving code. With the highly anticipated Refactoring to Patterns , Joshua Kerievsky has changed our approach to design by forever uniting patterns with the evolutionary process of refactoring. This book introduces the theory and practice of pattern-directed refactorings: sequences of low-level refactorings that allow designers to safely move designs to, towards, or away from pattern implementations. Using code from real-world projects, Kerievsky documents the thinking and steps underlying over two dozen pattern-based design transformations. Along the way he offers insights into pattern differences and how to implement patterns in the simplest possible ways. Coverage includes: A catalog of twenty-seven pattern-directed refactorings, featuring real-world code examples Descriptions of twelve design smells that indicate the need for this book’s refactorings General information and new insights about patterns and refactoring Detailed implementation mechanics: how low-level refactorings are combined to implement high-level patterns Multiple ways to implement the same pattern–and when to use each Practical ways to get started even if you have little experience with patterns or refactoring Refactoring to Patterns reflects three years of refinement and the insights of more than sixty software engineering thought leaders in the global patterns, refactoring, and agile development communities. Whether you’re focused on legacy or “greenfield” development, this book will make you a better software designer by helping you learn how to make important design changes safely and effectively.

Refactoring to Patterns

Kerievsky lays the foundation for maximizing the use of design patterns by helping the reader view them in the context of refactorings. He ties together two of the most popular methods in software engineering today--refactoring and design patterns--as he helps the experienced developer create more robust software.

Agility enables you, your team, and your organization to streamline slow and awkward actions, overcome obstacles quickly, and adapt to change with ease and grace. Agility isn’t a formula, a framework, nor a set of roles and rituals to follow. It’s a timeless way of being that matures with practice and skill. Becoming agile involves knowing the difference between being quick or hurrying, moving with ease or difficulty, being in or out of balance, graceful or awkward, adaptable or rigid, resourceful or resentful. With Joy of Agility, Joshua Kerievsky, CEO of Industrial Logic, one of the oldest and most-respected agile consultancies in the world, shows you how to harness agility in work and life to solve problems and succeed sooner. Kerievsky shares six essential agile mantras, plus unforgettable, real-world stories of agile people and teams, that will empower you to be quick, adaptable, and resourceful in the face of challenges and opportunities. Learn how to: Distinguish between being quick and hurrying Gain better balance and collaborate gracefully with others Prepare and practice being poised to adapt Take deliberate steps to drive out fear Grow a solution by starting minimal and evolving Overcome obstacles by being readily resourceful Use the lessons learned in Joy of Agility to transform agility from a mere buzzword into an approach that helps you obtain triumphant results.
