clang-format：class 声明结束和命名空间结束之间的空行

Question

我使用 clang-format 来格式化我们的 C++ 代码。我想在 class 声明和周围命名空间的右括号之间有一个空行，如下所示：

namespace Foo {

class Bar {
};

}

但是 clang-format 将我的代码更改为：

namespace Foo {

class Bar {
};
}

它删除了 class 声明和命名空间的右大括号之间的空行。

我的问题：有没有办法防止 clang-format 删除空行？

这是我当前的 clang 格式配置：

Answer 1

我找到了一种解决此问题的方法：向命名空间右括号添加内联注释，如下所示：

namespace my_namespace {

class MyClass {
    int n;
};

} // namespace my_namespace

clang-format：class 声明结束和命名空间结束之间的空行

clang-format: Empty line between end of class declaration and closing of a namespace
