我使用 clang-format 来格式化我们的 C++ 代码。我想在类声明和周围命名空间的右大括号之间有一个空行，如下所示：
namespace Foo {
class Bar {
};
}
但 clang-format 将我的代码更改为：
namespace Foo {
class Bar {
};
}
它删除了类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-format 配置：

我找到了解决此问题的一种方法：向命名空间右大括号添加内联注释，如下所示：
namespace my_namespace {
class MyClass {
int n;
};
} // namespace my_namespace
