I would like to second this question.
Several times recently, I have needed to wrap STL-like containers that are
almost-vectors, just different enough that vector_indexing_suite does not work.
This is a minor PITA with the standard indexing_suite and looks like it will be
much easier with the new one. Due to technical/political reasons, it is
difficult for us to use anything not on the mainline, in a numbered boost
distribution. It would be a big help if this got on the mainline.
Is there still a good reason not to?
PS: Jakob, I have some code that may help with the 'no operator()== problem":
//Thanks to Andreas Klöckner on "Development of Python/C++ integration"
<c++-...@python.org> for this code.
template <class T>
class no_compare_indexing_suite : public bp::vector_indexing_suite<T, false,
no_compare_indexing_suite<T> >
{
public:
static bool contains(T &container, typename T::value_type const &key)
{
PYTHON_ERROR(PyExc_NotImplementedError, "containment checking not
supported on this container");
}
};
Just use this where you would otherwise use vector_indexing_suite.

Subject: [C++-sig] Boost.Python indexing suite version 2?
Hello,
While attempting to wrap a vector of objects where the element class
doesn't define operator()==, I ran across a mention of a "Version 2"
of the indexing suite from 2003:
http://mail.python.org/pipermail/cplusplus-sig/2003-October/005453.html
While it's mentioned on the Py++ page, it doesn't seem to have made it
in to the main boost distribution in the intervening 5 years. Can
anyone tell me what happened to this project?
Thanks,
Jakob van Santen
