How to use Ctags with C++ trailing return types

Question

I've come to like C++11 style trailing return types, however when I wanted to use vim with my C++ program I noticed that ctags don't mix well with them.

I've tried exuberant ctags and universal ctags and both don't seem to work with trailing return types.

Is there some way to configure ctags to cooperate with trailing return types?

Answer 1

The latest Universal ctags can extract the name and the return type of a function with trailing return type:

auto f(void) -> int
{
    return 0;
}
$ ~/bin/ctags --version
