How to avoid namespace content indentation in vim?

Question

How to set vim to not indent namespace content in C++?

namespace < identifier >
{
    < statement_list > // Unwanted indentation
}

Answer 1

I've configured vim to not indent for the namespace. These are the relevant lines in my vimrc:

autocmd Filetype cpp set shiftwidth=2
set cino=>2(0^-2g0h2

Frankly, I don't remember how to interpet the cino statement, but :help cinoptions should help in deciphering it. One caveat: I think it's configured to not indent when using a format like so:

namespace foo 
{ // <- curly bracket on next line
...

versus

namespace foo { // <- same line

Since I put the curly bracket on the next line exclusively for namespaces, it does what I want, but it might not work if you use that style for other function declarations, for, etc.
