[pygccxml-development] [py++] vector of vectors trouble

[Maik B. <bec...@go...>]

Hello,

I got two problems with vector of vectors
  1. nested vector type isn't exported 
  2. renaming of "vector<vector<> >" doesn't work as expected

===============================================
===============================================

1. nested vector type isn't exported

test.hpp (include guards omitted)
{{{
#include <vector>
void bar(std::vector<std::vector<double> > vv) 
{ ... }
}}}

This is how I expect it to work in python
{{{
from pyMaik import vector_less__double__greater_ as vector_double
from pyMaik import 
vector_less__std_scope_vector_less__double__greater___greater_ as 
vvector_double
from pyMaik import foo

v1 = vector_double()
v1.append(1)
v2 = vector_double()
v2.append(2)

vv = vvector_double()
vv.append(v1)
vv.append(v2)

foo(vv)
}}}
However, it doesn't work because 
  std::vector<std::vector<double> > 
is exported, but
  std::vector<double>
not.  Adding a dummy to test.hpp
  void dummy(std::vector<double> v) { }
solves this problem, but I wonder if there is a better way to do this.

================================================

2. renaming of "vector<vector<> >" doesn't work as expected.

To change this
{{{
from pyMaik import vector_less__double__greater_ as vector_double
from pyMaik import 
vector_less__std_scope_vector_less__double__greater___greater_ as 
vvector_double
from pyMaik import foo
}}}
to
{{{
from pyMaik import vector_double, vvector_double, foo
}}}
I've added the following to generate_code.py
{{{
std = mb.namespace('std');

# do work:
#mb.class_('::std::vector<double>').rename('vector_double') 
std.class_('vector<double>').rename('vector_double')

# doesn't work:
#std.class_('vector<vector<double> >').rename('vvector_double')
#mb.class_('::std::vector<::std::vector< double > 
>').rename('vvector_double')# doesn't work
#works:
mb.class_('::std::vector< std::vector< double > >').rename('vvector_double')
}}}

As you can see from the comment vector<double> works nicely with, where
  std.class_('vector<double>').rename('vector_double')
is what I prefer.  For vector<vector<double> > I tried
  std.class_('vector<vector<double> >').rename('vvector_double')
but it doesn't work.  Then I tried 
  mb.class_('::std::vector<::std::vector< double > 
>').rename('vvector_double')
because because ::std::vector<double> worked above, but I it doesn't work 
either.  The only statement I've found to get what I want is
  mb.class_('::std::vector< std::vector< double > >').rename('vvector_double')
What are the rules (give me a RTFM with and a link if I missed it) ?



Thanks,
