In order to use type_traits  functionality it is necessary to import
declarations package from pygccxml

from pygccxml import declarations

Sorry, I forgot to write you this

Now this will fail for another reason: std::vector< std::string > is class
declaration,
as opposite to class definition. So if you will wrote next 2 lines as:

rtype_cls = declarations.class_declaration_traits.get_declaration( rtype )
rtype.alias = 'vector_of_strings'

This will work.

I also forgot to ask you what version of Py++ pygccxml you use.
Because in order to enjoy from semi automatic aliasing you need
latest version of py++ and pygccxml.

Automatic aliasing:
add next code somewhere in a file, which is passed to gccxml, in global
namespace:

namespace pyplusplus{ namespace aliases{
    typedef std::vector < std::string > vvvvvvvv;
}}

Py++ will automaticly pick the name
