I basically have an NSSet of objects which need to be filtered based on a user-provided logic. As the logic should not be limited to rather primitive NSPredicates I'd like to provide a barebones in-app Python editor in which the user can define his/her logic. There is however still one question that remained unanswered: Being able to instantiate an Objective-C object from Python is neat, but still isolated. How do I expose a particular object instance from one language to the other? After all I need to pass my Objective-C object to Python for evaluation and receive an answer from it in respose. A minimal sample function (as provided by the user at runtime) would look something like this: def shallRejectObject(object) if object.foo(): return True return False Being totally new to PyObjC I'm thinking of some kind of reverse "objc.lookUpClass(…)" to allow me to instantiate my Python subclass from within Objective-C. Or how else would one approach this? Any hints?

Is there a sample Xcode project that does this? I did see Bill Bumgarner's "Calling Python from Objective-C" example and it's helpful. But I'm hoping for a Cocoa sample in an Xcode context to work from if one is available. I realize that this isn't purely a PyObjC question but I thought this list would be a good place to ask it on.

The situation: I'm working on a .mailbundle (a plug-in for Apple Mail). From that plug-in, I want to start a PyObjC-based application. No matter what, this fails: the application gets a SIGSEGV (I'll post some more information below). I've used pretty much all methods of starting the application (NSWorkspace, NSTask, even executing "open -a APP" from the Python subprocess module), and it keeps failing. Of course, the app works without problems when started manually. Starting the app from a Python-shell using [NSWorkspace launchApplication:] works, too. Just not from within the plug-in. Even the simplest 'app' fails: -snip- from Foundation import * class MyTestClass(NSObject): pass -snip- Same thing: SIGSEGV. Starting other apps (like Safari) isn't a problem, so it doesn't seem to be some sandbox-type blocking. Below is the relevant part of the crashlog. All I've been able to find out is that objc_msgSend_vtable3 is an Objective-C runtime shortcut for getting 'self'. It smells like a memory issue, but I'd be grateful if anyone could help me out. -snip- Process: App1 [797] Path: /Users/USER/*/App1.app/Contents/MacOS/App1 Identifier: name.klep.app1 Version: 0.0.0 (0.0.0) Code Type: X86-64 (Native) Parent Process: launchd [301] Date/Time: 2011-11-21 06:49:06.394 +0100 OS Version: Mac OS X 10.7.2 (11C74) Report Version: 9 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00007fc2dac50c60 VM Regions Near 0x7fc2dac50c60: MALLOC_TINY 0000000104e00000-0000000104f00000 [ 1024K] rw-/rwx SM=PRV --&gt; STACK GUARD 00007fff5bc00000-00007fff5f400000 [ 56.0M] ---/rwx SM=NUL stack guard for thread 0 Application Specific Information: objc_msgSend() selector name: self objc[797]: garbage collection is OFF Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x00007fff8c84c0cd objc_msgSend_vtable3 + 13 1 _objc.so 0x0000000101ba5a71 pythonify_c_value + 573 2 _objc.so 0x0000000101b9d92e 0x101b80000 + 121134 3 org.python.python 0x0000000101a87b58 PyEval_EvalFrameEx + 13318 4 org.python.python 0x0000000101a8acd8 PyEval_EvalCodeEx + 1996 5 org.python.python 0x0000000101a8ae6c PyEval_EvalCode + 341 6 org.python.python 0x0000000101a87e0a PyEval_EvalFrameEx + 14008 7 org.python.python 0x0000000101a8acd8 PyEval_EvalCodeEx + 1996 8 org.python.python 0x0000000101a28abf PyClassMethod_New + 1378 9 org.python.python 0x0000000101a07d32 PyObject_Call + 97 10 org.python.python 0x0000000101a83c40 PyEval_CallObjectWithKeywords + 180 11 _objc.so 0x0000000101ba0bd3 0x101b80000 + 134099 12 org.python.python 0x0000000101a4cafa PyType_Modified + 891 13 org.python.python 0x0000000101a07d32 PyObject_Call + 97 14 org.python.python 0x0000000101a07eed PyObject_CallFunctionObjArgs + 178 15 org.python.python 0x0000000101a8576b PyEval_EvalFrameEx + 4121 16 org.python.python 0x0000000101a8acd8 PyEval_EvalCodeEx + 1996 17 org.python.python 0x0000000101a8ad4d PyEval_EvalCode + 54 18 org.python.python 0x0000000101aa208f Py_CompileString + 62 19 org.python.python 0x0000000101aa214f PyRun_FileExFlags + 157 20 org.python.python 0x0000000101a801f6 _PyBuiltin_Init + 4630 21 org.python.python 0x0000000101a87d77 PyEval_EvalFrameEx + 13861 22 org.python.python 0x0000000101a8acd8 PyEval_EvalCodeEx + 1996 23 org.python.python 0x0000000101a8ae6c PyEval_EvalCode + 341 24 org.python.python 0x0000000101a87e0a PyEval_EvalFrameEx + 14008 25 org.python.python 0x0000000101a8acd8 PyEval_EvalCodeEx + 1996 26 org.python.python 0x0000000101a8ad4d PyEval_EvalCode + 54 27 org.python.python 0x0000000101aa208f Py_CompileString + 62 28 org.python.python 0x0000000101aa214f PyRun_FileExFlags + 157 29 org.python.python 0x0000000101aa32a2 PyRun_SimpleFileExFlags + 392 30 name.klep.app1 0x0000000100004476 start + 12854 31 name.klep.app1 0x0000000100004a96 main + 1465 32 name.klep.app1 0x0000000100001274 start + 52 -snip- </pre> Robert Klep 2011-11-21T06:08:39 http://comments.gmane.org/gmane.comp.python.pyobjc.devel/5955 <pre>Hi, I just installed and Lion in Snow Leopard xoode pyobjc runs in 4.1,which version should install Xcode?

It's known to compile and work on: 1. GCC Objective-C runtime &lt; 4.6 2. GCC Objective-C runtime &gt;= 4.6 3. GNUstep Objective-C runtime (libobjc-2-1.5). To get this to work, you need GNUstep base and corebase from trunk. We've also integrated successfully PyObjC in the SOGo code (www.sogo.nu) - so it's now possible to fully extend SOGo's code using Python. Here is the patch - which could hopefully be included. Thanks, </pre> Ludovic Marcotte 2011-08-01T14:40:51 http://comments.gmane.org/gmane.comp.python.pyobjc.devel/5936 <pre>I'm trying to use httplib to send an http request in a background thread. It works fine on its own, but when I do it inside a Cocoa application, the thread hangs as soon as it tries to send the request. It doesn't seem to be a GIL problem, because I can do other things in the thread leading up to that point. It's just sending the request that seems to block. Is there anything I should be aware of when using the threading module in conjunction with pyobjc? </pre> Greg Ewing 2011-07-15T01:43:36 http://comments.gmane.org/gmane.comp.python.pyobjc.devel/5933 <pre> Hi. When I load UIKit with myUIKit = objc.loadBundle("UIKit", globals(), "/System/Library/Frameworks/UIKit.framework") I import a lot of symbols, but a few protocols such as UIImagePickerControllerDelegate and UINavigationControllerDelegate are not loaded with this occasion (probably because they are not used in any any other place). Could you please tell me if you have an idea on what goes wrong when using UIImagePickerController with UIImagePickerControllerDelegate in the code below. The symptom is the following: none of the methods of MyDelegate don't get called, although ipc.takePicture() should call them.

These can be defined in a submodule, as long as you arrange for that module to be loaded whenever someone imports your package."

I am trying to implement in PyObjC the program available at https://github.com/erica/iphone-3.0-cookbook-/tree/b8ca8905d17015839a0917e1dcd407d055890236/C07-Images/04-Snapping%20Images. Although I am a "beginner" in PyObjC, I spent a couple of days trying to very seriously translate this script to PyObjC and tried my best to find out all errors. However, it doesn't work: the application doesn't execute normally after entering viewDidLoad() - it doesn't change appearance of UI as specified there. I guess it has to do with the fact I am not loading (or using the specification) of the TestBedViewController.xib file, which describes properties of TestBedViewController - I translated only the main.m and did not use by any means the TestBedViewController.xib - I do not know how can I load this file in PyObjC on iOS... Please find the PyObjC code I wrote so far here: http://mobile-revival.110mb.com/ReVival/HelloPython.py . I run my PyObjC scripts on iOS version 3.1.2. PyObjC is version 1946-4, Python is version 2.5.1-5 (obtained with Cydia 1.1.1; and libffi is version 130618-4). Best regards.

The problem only seems to affect this particular font; all the other fonts I've tried are positioned correctly. This is the code I'm using to get the baseline of the text positioned at (x, y): h = ns_font.defaultLineHeightForFont() d = -ns_font.descender() ns_point = NSPoint(x, y - h + d) ns_string.drawAtPoint_withAttributes_(ns_point, ns_attrs) Am I doing anything wrong here? I've checked the values that Cocoa is getting for defaultLineHeightForFont and descender, and they seem to be correct, but the text comes out in the wrong place when using that font. </pre> Greg Ewing 2011-06-26T07:55:06 http://comments.gmane.org/gmane.comp.python.pyobjc.devel/5916 <pre>I notice that at the end of last year Ronald said he intended to move the PyObjC repository from SVN to mercurial, to join py2app and friends which have already been transferred. In an attempt to be helpful and for my own purposes I have successfully (I hope) created a copy of the PyObjC SVN repository using mercurial at bitbucket: https://bitbucket.org/lakka/pyobjc All history/branches/tags have been preserved (though some of them might usefully be closed off), but please open an issue if you find any problems. I would be delighted if Ronald wanted to move/clone this into his account! I hope soon to be able to contribute to the project some work I have done reorganising the Sphinx documentation and updating the examples.

One of the windows has a NSTextView in it. I connected it to an object also referenced in the interface builder file. The goal is to write to the NSTextView from a background trhead that does some task. I launch the thread with a call to NSThread.alloc().initWithTarget_selector_object_() The behaviour I am getting is erratic. Most times it blocks on the call to the NSTextView's setString_() method and the application hangs. If I run the code on the main thread it runs fine. How do I do this from a background thread ? The idea is to keep the application responsive. I am on : snow leopard (10.6.7) pyObjc (I think it is 2.2b3 (can you tell me how to really check the version ?))
