ANNOUNCE: PyBindGen 0.8
by Gustavo Carneiro 10 Mar '22

10 Mar '22

The other day I released PyBindGen 0.8. Main news is that it features a new experimental header file scanner based on pygccxml (i.e., it's similar to py++ in scope, if not in maturity, but does not use boost.pythonunderneath). == What == 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, and does not depend on any library or header files besides Python itself. == Where == https://launchpad.net/pybindgen/ == NEWS == - Support C++ instance attributes through getter/setter methods - Support functions as methods of C++ classes - Support the PyObject* type - Support unsigned int, C strings (char*) (from Mark Lee) - Add basic support for enum types - New experimental automatic module generator based on C/C++ header file scanner and annotations in comments, using pygccxml - Some bug fixes -- Gustavo J.

C API equivalent to abc.ABCMeta.register?
by Daniel Stutzbach 02 Mar '22

I'm the author of an extension module (blist) that provides a type that fits the MutableSequence API. Is there a canonical way for me to register the type as a MutableSequence from the C API? -- Daniel Stutzbach, Ph.D. President, Stutzbach Enterprises, LLC <http://stutzbachenterprises.com>

[capi-sig]Some work on reorganizing header files of CPython
by Victor Stinner 08 Nov '18

08 Nov '18

Hi, I working on the Include/ directory of CPython to separate the different levels of API into subdirectories: Move internal headers to Include/internal/ : https://bugs.python.org/issue35081 Move !Py_LIMITED_API to Include/pycapi/: https://bugs.python.org/issue35134 I also started to use replace macros with static inline functions: Convert Py_INCREF() and PyObject_INIT() to inlined functions https://bugs.python.org/issue35059 All these changes are connected to my https://pythoncapi.readthedocs.io/ project. It's the very first steps towards a better C API. The most concrete changes are that Py_BUILD_CORE are now in separated header files and so removed from Include/. You have to explicitly include pycode_xxx.h (ex: pycode_accu.h). Victor
