第 13 章 一堆

有时，你读到的代码被分割成许多小块，但却妨碍了你对它的理解。根据需要尽可能多地内联代码，直到所有代码都集中在一起。 在此基础上进行 Tidy。
代码的最大成本是阅读和理解代码的成本，而不是编写代码的成本。Tidy 首先偏向于使用大量的小片段，理论上是为了增加内聚性，以此来减少耦合；实际上是为了减少在任何时候都需要在头脑中掌握的细节量。
这种偏向于小片段的目标是使代码能够一次理解一点。但有时，这个过程会出错。由于小片段之间的相互作用，代码变得更加难以理解。为了恢复代码的清晰度，首先必须将代码捋顺，然后才能提取出新的、更容易理解的部分。
您要寻找的一些症状是
-
冗长、重复的参数列表
-
重复代码，尤其是重复条件
-
辅助例程命名不当
-
共享可变数据结构
由于偏向于更多、更小的作品，在整理时堆成一堆感觉很奇怪。然而，这却让我感到莫名的满足。我一直在尝试理解零散的代码。我开始怀疑自己的能力。我转了 180 度，开始将所有代码集中在一起（自动重构真的很有帮助，但如果有必要，我也会手动重构）。真是如释重负！
随着这堆东西越积越多，我的脑海中开始浮现出它的形状。我明白了--我们先计算这个，然后用它来计算那个！他们为什么不直说呢？现在，我可以提出标题问题：我应该先整理呢？还是只做我现在看到的改动？
