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>

Re: [capi-sig] exceptions, the right way
by Lee 18 Nov '11

Hi, > Maybe you are compiling noddy2 with a > compiler incompatible to the one used for building Python? Thanks Hrvoje for the hint! Actually I was linking against the python26.lib, changed to libpython26.a and it is working. For these tests I was using Dev-C++, the ultimate goal would be to use assembler. But for the moment, no joy with the assembler (even using libpython26.a), it seems that PyExc_TypeError and alike are the only culprits, the rest is OK. (Stefan: Cython looks impressive, I will look at it, if this path I took doesn't work, thanks for the suggestion). Lee

exceptions, the right way
by Lee 18 Nov '11

18 Nov '11

Hi All, I am new to Python C/API, I am trying to follow the official docs, but I am confused about raising and catching exceptions from an extension. For the example provided at Extending and Embedding the Python Interpreter 2. Defining New Types 2.1.2. Providing finer control over data attributes eg I don't seem to be able to catch the exceptions raised by the getsetters functions, the interpreter will just end up in an ugly crash. Something like: try: del mynoddy.last except TypeError, e: print "Error: ", e doesn't work. I understand that PyErr_SetString just sets the error and does not raises the exception. Am I missing something? I am using Python ver 2.6.6 on Windows. Any advice is greatly appreciated, Lee
