代码整洁之道
代码整洁之道
“阅读这本书有两种原因：*，你是个程序员；第二，你想成为更好的程序员。很好，IT行业需要更好的程序员！”——罗伯特·C. 马丁（Robert C. Martin） 尽管糟糕的代码也能运行，但如果代码不整洁，会使整个开发团队泥足深陷，写得不好的代码每年都要耗费难以计数的时间和资源。但是，这种情况并非无法避免。 著名软件专家罗伯特·C. 马丁（Robert C. Martin） 在本书中为你呈现了革命性的视野。他携同Object Mentor公司的同事，从他们有关整洁代码的*敏捷实践中提炼出软件技艺的价值观，以飨读者，让你成为更优秀的程序员——只要你着手研读本书。 阅读本书需要你做些什么呢？你将阅读代码——大量代码。本书会促使你思考何谓正确的代码，何谓错误的代码。更重要的是，本书将促使你重新评估自己的专业价值观，以及对自己技艺的承诺。 书中的具体内容包括： ·好代码和糟糕的代码之间的区别； ·如何编写好代码，如何将糟糕的代码转化为好代码； ·如何创建好名称、好函数、好对象和好类； ·如何格式化代码以实现其可读性的*化； ·如何在不妨碍代码逻辑的前提下充分实现错误处理； ·如何进行单元测试和测试驱动开发。
软件质量，不但依赖架构及项目管理，而且与代码质量紧密相关。这一点，无论是敏捷开发流派还是传统开发流派，都不得不承认。 本书提出一种观点：代码质量与其整洁度成正比。干净的代码，既在质量上较为可靠，也为后期维护、升级奠定了良好基础。作为编程领域的佼佼者，本书作者给出了一系列行之有效的整洁代码操作实践。这些实践在本书中体现为一条条规则（或称“启示”），并辅以来自实际项目的正、反两面的范例。只要遵循这些规则，就能编写出干净的代码，从而有效提升代码质量。 本书阅读对象为一切有志于改善代码质量的程序员及技术经理。书中介绍的规则均来自作者多年的实践经验，涵盖从命名到重构的多个编程方面，虽为一“家”之言，然诚有可资借鉴的价值。
