The Refactoring book completely changed the way I code.
In 2001 while searching for information on design patterns, I discovered the original wiki, and stumbled on Extreme Programming. This led me to a software development conference in 2002 called SD West. There I attended a session by Martin Fowler, and knew that I had to pick up his Refactoring book that day.
How could I resist a book that promised to teach me about “improving the design of existing code”?
Many years later, I find the term “refactoring” being thrown around in the workplace, at company after company. Programmers and managers often talk about “refactoring,” when they mean “rewriting.” I’ve seen nightmares brought about by so-called “refactoring” that introduced so many defects, it compromised the product ship date.
The Refactoring book, however, teaches a disciplined methodology of changing code in small steps, with automated verification of each step.
Of the books I keep at work, a small handful are kept within easy reach for looking things up. This is one of those books. Each refactoring has a detailed recipe of its steps, and things go better when I open the book to follow those precise steps.
If my statement that it “completely changed the way I code” seems like hyperbole, another blogger states it even more strongly: “That moment changed my life.”
Would you like to transform ugly code to make it better, but do so safely? What are you waiting for… buy a copy of the Refactoring book today!
Question: What has been your experience with refactoring? Leave a comment below.
Programming was fun when I was a kid. But working in Silicon Valley, I saw poor code lead to fear, with real human costs. Looking for ways to make my life better, I learned about Design Patterns, Refactoring, and Test-Driven Development (TDD). Programming became fun again! I've now been doing TDD in Apple environments for 17 years. I'm committed to software crafting as a discipline, hoping we can all reach greater effectiveness and joy.
