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>

Storing bytecode files in an alternative directory
by Terry Westley 14 Oct '11

14 Oct '11

PEP 304 was withdrawn, but those of us embedding Python need a way to put .py files in read-only memory and .pyc files in a separate writable directory. Short of resurrecting PEP 304, is there a known mod that I could use for this purpose? My situation is an iPhone/iPad app (http://www.sabonrai.com/PythonMath/). Python source files need to be part of the app bundle which is in a non-writable directory. I've found that even compiling all the .py files doesn't work because the interpreter wants to rebuild .pyc files for certain modules and I get an unlink deny error for them. Terry
