Refactoring is about improving the design of existing code. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure. With refactoring you can even take a bad design and rework it into a good one. This book offers a thorough discussion of the principles of refactoring, including where to spot opportunities for refactoring, and how to set up the required tests. There is also a catalog of more than 40 proven refactorings with details as to when and why to use the refactoring, step by step instructions for implementing it, and an example illustrating how it works The book is written using Java as its principle language, but the ideas are applicable to any OO language.
Features
The first update to a classic that is the standard reference for refactoring in over 15 years
Enhanced, web-based features including interactive examples, video snippets, code highlighting
Extensive use of JavaScript examples
New to This Edition
Martin Fowler is retaining everything that made Refactoring one of the world’s most popular and influential computer books, while updating with JavaScript examples throughout (to address many programmers’ current preferences) and reflecting today’s programming paradigms. The book’s catalog of individual refactorings has been updated, revised, and expanded.
Martin Fowler is Chief Scientist at ThoughtWorks. He describes himself as “an author, speaker, consultant and general loud-mouth on software development.” Fowler concentrates on designing enterprise software: exploring what makes a good design and what practices are needed to create one.
第二版有瞭不少改進,比如代碼換成瞭js(用的是最新的ES語法),重構都配瞭示意圖。收獲非常大。
評分比之第一版,更注重細節功夫,重構過程更完備更流程,更注重行為保持,大規模的重構全部刪去。可以體現作者的理念:於細節處見成敗。

評分雖然例子是用JS寫的,思想都是通的。前幾章看完幫助非常大,很多平時寫代碼時候會糾結的地方從這裏可以找到答案。講的原則可操作性非常強,很多思想可以直接影響現在的工作方式。具體每個重構技巧比較繁雜,沒仔細看完,可以有需要再拿齣來翻。印象深刻的幾個點:“不要專門和老闆說我要重構,而是作為功能的一部分”,“保持修改後的代碼比現在的代碼好”,“大部分情況:可讀性>性能”,“profiling找性能瓶頸,直覺大部分情況是錯的”解決。

2009年,在为《重构》第一版的中译本再版整理译稿时,我已经隐约察觉行业中对“重构”这个概念的矛盾张力。一方面,在这个“VUCA”(易变、不确定、复杂、模糊)横行的年代,有能力调整系统的内部结构,使其更具长期生命力,这是一个令人神往的期许。另一方面,重构的扎实工夫...
評分重构是设计,设计是art,重构也是art. 一个函数三行只是语不惊人死不休的说法,是对成百上千行代码的矫枉过正。 更一个般的看法是一个函数应该写在一页纸内。但举一个上百行的极端例子也是可能的。比如某种数值计算。 重构的意义应该在XP的背景下看,如果没有重构,XP的方法从...

評分书中说过重构的思想由来已久,只不过没人写成书籍罢了。 个人感觉如果你看完这本书只看到了思想,那你就错过了很多有价值的东西。小步骤的重构,如何最大限度的不引入bug才是书中要告诉大家的。像了解重构思想,只看前几章就够了。我个人认为书中最有价值的东西恰恰是进行重构...
評分代码的坏味道章节描述了常见的不良代码,而且基本上流行于各种编程语言。 第6~11章概括了一些java中的重构手法,是作者在实际操作过程中重构笔记的基础上总结而成,对于我们非Java程序员来说选择性阅读即可。 重构手法中包含了不少譬如提炼函数和内联函数这样的相反的操作,这...
