The source code for py_cpp, including a MSVC demo project is available <a
|
|
href="py_cpp_20001106.zip">here</a>.
|
|
|
|
<h2>Synopsis</h2>
|
|
<p>
|
|
py_cpp is a system for quickly and easily interfacing C++ code with <a
|
|
href="http:www.python.org">Python</a> such that the Python interface is
|
|
very similar to the C++ interface. It is designed to be minimally
|
|
intrusive on your C++ design. In most cases, you should not have to alter
|
|
your C++ classes in any way in order to use them with py_cpp. The system
|
|
<em>should</em> simply "reflect" your C++ classes and functions into
|
|
Python.
|
|
|
|
<h2>Supported Platforms</h2>
|
|
<p>py_cpp has been tested in the following configurations:
|
|
|
|
<ul>
|
|
<li>Against Python 1.5.2 using the following compiler/library:

|
<p>Py_cpp requires the <a href="http://www.boost.org">boost</a> libraries, and is
|
|
has been accepted for inclusion into the boost libraries pending "boostification"
|
|
(completion of the documentation, change in some naming conventions and
|
|
resolution of some namespace issues).

<h2>Credits</h2>
|
|
<p>
|
|
<ul>
|
|
<li><a href="mailto:abrahams@mediaone.net">David Abrahams</a> originated
|
|
and wrote py_cpp.
|
|
|
|
<li><a href="mailto:koethe@informatik.uni-hamburg.de">Ullrich Koethe</a>
|
|
had independently developed a similar system. When he discovered py_cpp,
|
|
he generously contributed countless hours of coding and much insight into
|
|
improving it. He is responsible for an early version of the support for <a
|
|
href="overloading.html">function overloading</a> and wrote the support for
|
|
<a href="inheritance.html#implicit_conversion">reflecting C++ inheritance
|
|
relationships</a>. He has helped to improve error-reporting from both
|
|
Python and C++, and is currently doing valuable research into <a
|
|
href="special.html#reasons">the best approach for numeric coercion</a>.
|
|
|
|
<li>The members of the boost mailing list and the Python community supplied
|
|
invaluable early feedback. In particular, Ron Clarke, Mark Evans, Anton
|
|
Gluck, Ralf W. Grosse-Kunstleve, Prabhu Ramachandran, and Barry Scott took
|
|
the brave step of trying to use py_cpp while it was still in early stages
|
|
of development.
|
|
|
|
<li>The development of py_cpp wouldn't have been
|
|
possible without the generous support of <a href="http://www.dragonsys.com/">Dragon Systems/Lernout and
|
|
Hauspie, Inc</a> who supported its development as an open-source project.

<h2>Naming Contest</h2>
|
|
|
|
<p>
|
|
Yes, I know py_cpp is a lousy name. Problem is, the best names my puny
|
|
imagination can muster (IDLE and GRAIL) are taken, so I'm holding a
|
|
naming contest. First prize? You get to pick the name<0.2wink> and
|
|
you will be credited in the documentation. Names that have been suggested
|
|
so far include:
|
|
<ul>
|
|
<li>
|
|
Py++
