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.
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...
評分第一遍于两年前, 让我了解到bad smell们, 还有那冗长的手法catalog. 最近第二遍, 回顾过去, 虽然bad smell的提示和重构操作已经完全融入现代IDE中了, 但总结下来它对我的影响还有如下: 1.我常常通过重构来加深对代码的理解. 2.让我变成一个十足的代码洁癖者, "刻"代码上瘾...
評分纸张很赞,只是排版松散,书就比较厚了。 本人对代码有洁癖,不自觉的一直会调整过去的代码,也需要对照大师总结的规律反思一下。 重构的基础能力在于能够嗅出代码中的坏味道(Bad smell),甚至反模式(Anti-pattern),因此要结合相关书籍一起阅读了。 最近在看的肖鹏一篇文...
評分适合写过两年代码的开发人员的一本书。 示范代码难度不是很高,主要就是理解里面的一种精神了。 我才看了一章,希望能坚持看完。
評分整体通俗易懂, 翻译过程有些小错, 不知道有没有勘误表 (1)184页下面范例跳了好几步 (2)187页范例, 数组说三个元素,代码只列出两个, "失败场次"没有了, (3)282页, 的代码sentAlert()函数好像有问题, 变成递归了. (4)306页, Raname Method明显是印刷错误了.
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。
评分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。
