                问题描述

                我正在 Visual Studio 2008 中处理一个大型 C++ 项目,并且有很多文件带有不必要的 #include 指令.有时 #include 只是工件,删除它们后一切都会很好地编译,而在其他情况下,可以向前声明类,并且可以将 #include 移动到 .cpp 文件.有没有什么好的工具可以检测这两种情况?

                I am working on a large C++ project in Visual Studio 2008, and there are a lot of files with unnecessary #include directives. Sometimes the #includes are just artifacts and everything will compile fine with them removed, and in other cases classes could be forward declared and the #include could be moved to the .cpp file. Are there any good tools for detecting both of these cases?

                推荐答案

                虽然它不会显示不需要的包含文件,但 Visual Studio 有一个设置 /showIncludes(右键单击 .cpp 文件,Properties->C/C++->Advanced) 将在编译时输出所有包含文件的树.这有助于识别不需要包含的文件.

                While it won't reveal unneeded include files, Visual studio has a setting /showIncludes (right click on a .cpp file, Properties->C/C++->Advanced) that will output a tree of all included files at compile time. This can help in identifying files that shouldn't need to be included.

                您还可以查看 pimpl idiom,以减少头文件依赖项,从而更轻松地查看可以删除的内容.

                You can also take a look at the pimpl idiom to let you get away with fewer header file dependencies to make it easier to see the cruft that you can remove.
