How to auto indent a C++ class with 4 spaces using clang-format?

Question

I got the next .clang-format file in my project\'s root directory:

---
AlignTrailingComments: true
AllowShortFunctionsOnASingleLine: false
AllowShortIfStatements

I managed to achieve the effect you want by changing both AccessModifierOffset with IndentWidth. Basically, the first is used as an offset of the second, so if you create your .clang-format like this you get what you want:

AccessModifierOffset: -4
IndentWidth:     8

If AccessModifierOffset is 0, the public keyword would be at the same level of indentation as the members. However, changing IndentWidth will indent all code by 8 spaces, even those outside the class declaration. This is a sample code:

class Foo {
    public:
        Foo();
        virtual ~Foo(); };

int main(int argc, char *argv[]) {
        std::cout << "Hello world" << std::endl;
        return 0;
}
