Hey Guys, My first post on this list so I hope this is the right place to post and relevant. Im rewriting parts of the Blender3D python API that has got a bit old and needs an update.
Im making a PyList subtype with the C/Python API, this involves intercepting calls to standard list methods to make sure Blenders array data is in Sync with the list's data. Iv got it working for tp_as_sequence, tp_as_mapping, iter and dealloc etc but methods are a problem. I want to add my own call's before and after PyLists standard functions but have a proplem with functons that use keywords and have no API equivalent. For example, I cant use the API's PyList_Sort because that dosnt support keywords like... ls.sort(key=lambda a: a.foo)) And the Problem with PyObject_CallMethod is that it dosnt accept keywords. PyObject_CallMethod((PyObject *)mylist, "sort", "O", args); Looking at abstract.c, PyObject_CallMethod uses call_function_tail, which calls "PyObject_Call(callable, args, NULL);" - so Its not currently possible with PyObject_CallMethod. But I cant find any way to do this in a few lines. I could use PyEval_CallObjectWithKeywords but that would mean Id need to get the method from the list manually which Ill look into, but unless Im missing something here, it seems PyObject_CallMethodWithKeywords would be a nice addition to the Python API that cant be done in a straight forward way at the moment. - Thanks _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
