PyBindGen is a Python module that is geared to generating C/C++ code that
binds a C/C++ library for Python. It does so without extensive use of either
C++ templates or C pre-processor macros. It has modular handling of C/C++
types, and can be easily extended with Python plugins. The generated code is
almost as clean as what a human programmer would write.
It can be downloaded from:
Bug reports should be filed here:
=== pybindgen 0.14 ===
- Multiple inheritance support
- Virtual methods can now be overridden with Method instead of _Method
- Add annotation support for instance attributes
- Benchmarks (vs Boost.Python, SWIG, and SIP)
- New types supported: int16_t& and std::string* parameter types
- Non-virtual protected methods are now also wrapped
- Wrap enum pointer params
Note: this release marks the beginning of a transition to a minor change
in the API of the generated bindings.
Prior to PyBindGen version 0.14, the code generated to handle C++
virtual methods required Python user code to define a _foo method in
order to implement the virtual method foo. Since 0.14, PyBindGen
changed so that virtual method foo is implemented in Python by
defining a method foo, i.e. no underscore prefix is needed anymore.
Setting pybindgen.settings.deprecated_virtuals to True will force the
old virtual method behaviour. But this is really deprecated; newer
code should set pybindgen.settings.deprecated_virtuals to False.
In PyBindGen 0.14, if the option
pybindgen.settings.deprecated_virtuals is not set, PyBindGen emits a
warning and assumes the value of True in order to preserve backward
compatibility. In PyBindGen 0.15, the default value of this option
will change to False, and in 0.16 the support for deprecated virtuals
will be removed.
This change was made to make the user code interface more intuitive,
and to align it with other Python bindings tools such as SIP,
Boost.Python, and SWIG.
