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>

Could you check the version numbers of those two DLLs. It's possible that you're loading a Python DLL for say 3.2.1 and one for 3.2.2. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Oct 07 2013) >>> Python Projects, Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope/Plone.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ 2013-10-14: PyCon DE 2013, Cologne, Germany ... 7 days to go ::::: Try our mxODBC.Connect Python Database Interface for free ! :::::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.

The same Python DLL loaded twice
by Mateusz Loskot 07 Oct '13

07 Oct '13

Hi, I'm experiencing strange issue with the very same python32.dll being loaded twice on Windows. I have an application which embeds Python. Launching my app loads python32.dll for the first time and all seems working well. Next, under the embedded Python, I execute this one-liner "import tkinter" This triggers loading of _tkinter.pyd, tk85.dll, tcl85.dll as well as python32.dll for the second time. The duplicate python32.dll is loaded into different address space, maintains its own thread state, leading to crash from PyInit__tkinter, obviously. The problem seems to be similar to this one http://stackoverflow.com/questions/2147729/dll-file-loaded-twice-with-dll-r… Has anyone experience similar issues? Any ideas on possible reasons of duplicate loading of python32.dll? Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

Help upgrading from an older version
by david 01 Oct '13

01 Oct '13

Hi: I have a game, which uses Python, called Jewel Quest The Sapphire Dragon by iWin.com. I also use a program, which helps me keep my programs up to date, called Secunia PSI. It shows the Python 2.7.x is out of date. The file location is C:\Program Files(x86)\iwin.com\Jewel Quest The Sapphire Dragon\python27.dll and the installed version is 2.7.1150.1103. According to my searches, Python is available up to vers. 2.7.5. How do I Update/Upgrade this version of Python to a newer version. When I tried to update previously, it either wanted me to install a new program (C:\Python) or replace the game directory. What are the proper steps to upgrade the portion of the game I need? Thanks David Riseberg d.riseberg(a)verizon.net
