Solved. Thanks everyone

Yes. Well pretty close. Py++ code generator

Thanks Troy for the helpful tip.
I'm still confused by the "as<>" symbol. I

That's clever. I wonder ho

I have not seen this cctbx product before. It especially interesting

If I have a C++ api like:

using mds-utils, would
I am trying to coax boost.python to automatically convert python files
to C++ std::ostreams, for methods that take arguments of type
"std::ostream&". I have made some progress, and I could use some
advice on how to go further.
I created a derived class of std::ostream, called FilestarOstream,

Py++ has produced for me over 97,000 lines of beautiful boost.python
wrapping code on my project, using less than 2500 lines of python.
But I am still experiencing some minor troubles that prevent me from
completing my project.
Suppose I wish to wrap the following:
//## foo.h ###
stru
Below is a simplified example of a tricky wrapping problem I have
encountered. The example remains somewhat complicated, but further
simplification results in a file that causes no trouble.
I get a compile error when I try to build the boost python code
generated by the following case:

Single-argument C++ constructors in pyplusplus seem to generate a
boost::python::implicitly_convertible tag, even when the constructor
is declared "explicit" in C++. That doesn't sound right to me.
Shouldn't a pair of types that are not implicitly convertible in C++,
also not be implicitly convert
Please help. I am just a beginner with pyplusplus and am not smart
enough to see how to create certain complex rules.
How would I create a pyplusplus rule for setting the return policy to
"return internal reference" for all member functions that meet the
following criteria:
* method name begins
15 matches
