我总是说‘这就是我要做的’。我不会试图教训他们，告诉他们他们的代码是垃圾，而只是给他们一个不同的观点，希望能向他们展示一些明显更整洁的东西。

根据我的经验，曾经有一段时间，我们想要将一个windows应用程序更改为一个web应用程序并进行优化，因为它更容易更新和维护。但由于我的朋友是windows应用程序的主要贡献者，他不允许更改，然后剩下的就是历史了。

寓意:为了代码优化和更好的维护，在任何编程环境中，重视组织的目标都比重视个人的目标更重要。

糟糕的命名习惯:总是不可原谅的。

是的，不要总是认为你的方式更好……这可能很困难，但必须保持客观性。

I've had an experience with a coder that had such horrible naming of functions, the code was worse than unreadable. The functions lied about what they did, the code was nonsensical. And they were protective/resistant to having someone else change their code. when confronted very politely, they admitted it was poorly named, but wanted to retain their ownership of the code and would go back and fix it up "at a later date." This is in the past now, but how do you deal with a situation where they error is ACKNOWLEDGED, but then protected? This went on for a long time and I had no idea how to break through that barrier.

Global variables: I myself am not THAT fond of global variables, but I know a few otherwise excellent programmers that like them A LOT. So much so that I've come to believe they are not actually all that bad in many situations, as they allow for clarity, ease of debugging. (please don't flame/downvote me :) ) It comes down to, I've seen a lot of very good, effective, bug free code that used global variables (not put in by me!) and great deal of buggy, impossible to read/maintain/fix code that meticulously used proper patterns. Maybe there IS a place (though shrinking perhaps) for global variables? I'm considering rethinking my position based on evidence.

以一种非对抗性的方式提出一个更好的选择。

“嘿，我觉得这个方法也可以。你们怎么看?”[用手势表示屏幕上的代码明显更好]

在Gerry Weinberg的书《计算机编程心理学》中有一些非常好的建议——他的“无我编程”的整个概念都是关于如何帮助人们接受对他们代码的批评，而不是对他们自己的批评。

这里的许多答案都与代码格式有关，但现在并不是特别相关，因为大多数ide将按照您选择的样式重新格式化代码。真正重要的是代码是如何工作的，海报是正确的查看全局变量，复制和粘贴代码，以及我的烦恼，命名约定。糟糕的代码是存在的，这与格式没有多大关系。

好的方面是，大多数情况下都有很好的原因，这些原因通常是可量化和可解释的。所以，用一种非对抗性的方式解释原因。在许多情况下，您甚至可以为作者提供问题变得明显的场景。
