问题描述
我目前正在开发一个大型的旧 C++ 应用程序，在我之前有很多开发人员.项目、类和函数中有很多死代码"，不再被任何人使用.
I'm currently working on a large and old C++ application that has had many developers before me. There is a lot of "dead code" in the project, classes and functions that aren't used by anyone anymore.
有哪些工具可用于 C++ 分析大型代码库以检测和重构死代码?注意:我不是在谈论像 gcov 这样的测试覆盖率工具.
What tools are available for C++ to make a analysis of large code base to detect and refactor dead code? Note: I'm not talking about test coverage tool like gcov.
你如何在你的项目中找到死代码?
How do you find dead code in your project?
推荐答案
您需要使用静态分析工具
- StackOverflow:有哪些开源 C++ 静态分析工具可用?
- 维基百科:静态代码分析工具列表
我遇到的主要问题是，您必须小心不要从您无法控制/拥有的地方使用任何库.如果您从一个通过引用项目中的库而被使用的类中删除一个函数，您可能会破坏一些您不知道使用该代码的东西.
The main gotcha I've run into is that you have to be careful that any libraries aren't used from somewhere that you don't control/have. If you delete a function from a class that gets used by referencing a library in your project you can break something that you didn't know used the code.
