Cpp2Py: a C++/Python interfacing tool

Cpp2Py is a standalone tool that generates the necessary wrapping code between C++ and Python. Wrapping C++ functions and classes in Python is a non trivial problem because the two languages are quite different (e.g. C++ uses typically value semantics, while Python uses only counted documentation/manual/triqss, the C++ equivalent of std::shared_ptr).

This tool has the following main features:

• it is entirely automatic in most cases, i.e. except for some advanced features that require additionnal inputs.

• it is quite flexible.

• it can be used with a magic cell command in the Python notebook.

• Convertion vs wrapping
  • Wrapping classes from C++ to Python
  • Convertion
• General Principle
• Python API of the desc file
  • The module_ class
  • The cfunction class
  • The class_ class
