Vim C / C ++ indentation does not work well when type and name are on different lines

Question

The following code snippets explain my problem well.

What I want:

template<class T>
ostream& operator<<(ostream& out, const vector<T>& v)
{
    ...
}

int
main()
{
    ...
}

What I get (note the excessive deviation before the function name):

    template<class T>
ostream& operator<<(ostream& out, const vector<T>& v)
{
    ...
}

    int
main()
{
    ...
}

I have set filetype plugin indent onin mine ~/.vimrc.

I looked through this post , but the answer to this question looks like learning a new programming language. I'm a vim fan but not a vim expert. Is there no simpler solution?

Answer 1

, , cino-t ( cinoptions t). , conniptions t0,

:h cino-t

            cino=               cino=t0             cino=t7
                  int             int                        int
              func()              func()              func()

, cpp. (cindent cpp )
