dry - 是否有自动工具来查找代码库的 DRY 性？

Question

我是 DRY principle 的坚定拥护者:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

是否有任何工具可以测试代码库的 DRYness 数量并量化和精确定位特定示例以进行更正？

Answer 1

PMD Copy Past Detector (CPD)

Duplicate code can be hard to find, especially in a large project. But PMD's Copy/Paste Detector (CPD) can find it for you!

Note that CPD works with Java, JSP, C, C++, Fortran and PHP code.

您可以在命令行中运行它，有一个 ANT 任务和一个 Eclipse 插件。
