py2app warning: may need to include email.Util
by Russell E Owen Aug. 6, 2007

Aug. 6, 2007

My py2app-bundled Mac application recently started failing with "no module named email.Util" when trying to display images. It turns out pyfits uses urllib which uses email.Util, which apparently has been renamed email.util with some kind of clever lazy import code so one can still use email.Util. Apparently the cleverness is too much for py2app's module finder. Anyway, the easy workaround is to specify email.Util as a necessary module to import. But I'll report a python bug or submit a urllib patch. -- Russell

py2app and Adobe AIR problem

hi, I'm trying to bundle the Adobe AIR framework and my Python application with py2app. But I'm getting the error below as soon as macholib (1.1 or 1.2-dev) starts to analyze the executable in the AIR framework. [exec] copying /Developer/SDKs/flex3/runtimes/air/mac/Adobe AIR.framework/Adobe AIR -> /Users/thijstriemstra/Sites/software/rtmpy/ samples/branches/rtmpyapp-py2app/dist/RTMPyApp.app/Contents/Frameworks [exec] Traceback (most recent call last): [exec] File "/Library/Frameworks/Python.framework/Versions/ 2.5/lib/python2.5/site-packages/py2app-0.3.6-py2.5.egg/py2app/ build_app.py", line 548, in _run [exec] self.run_normal() [exec] File "/Library/Frameworks/Python.framework/Versions/ 2.5/lib/python2.5/site-packages/py2app-0.3.6-py2.5.egg/py2app/ build_app.py", line 619, in run_normal [exec] self.create_binaries(py_files, pkgdirs, extensions, loader_files) [exec] File "/Library/Frameworks/Python.framework/Versions/ 2.5/lib/python2.5/site-packages/py2app-0.3.6-py2.5.egg/py2app/ build_app.py", line 731, in create_binaries [exec] mm.mm.run_file(fmwk) [exec] File "/private/tmp/trunk/macholib/MachOGraph.py", line 66, in run_file [exec] m = self.createNode(MachO, pathname) [exec] File "/private/tmp/trunk/macholib/MachOStandalone.py", line 23, in createNode [exec] res = super(FilteredMachOGraph, self).createNode (cls, name) [exec] File "build/bdist.macosx-10.3-fat/egg/altgraph/ ObjectGraph.py", line 148, in createNode [exec] m = cls(name, *args, **kw) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 61, in __init__ [exec] self.load(file(filename, 'rb')) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 71, in load [exec] self.load_fat(fh) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 82, in load_fat [exec] self.load_header(fh, arch.offset, arch.size) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 106, in load_header [exec] hdr = MachOHeader(self, fh, offset, size, magic, hdr, endian) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 146, in __init__ [exec] self.load(fh) [exec] File "/private/tmp/trunk/macholib/MachO.py", line 178, in load [exec] raise ValueError("Unknown load command: %d" % (cmd_load.cmd,)) [exec] ValueError: Unknown load command: 27 [exec] > /private/tmp/trunk/macholib/MachO.py(178)load() [exec] -> raise ValueError("Unknown load command: %d" % (cmd_load.cmd,)) [exec] (Pdb) The .app file is created but I'm not sure if it will work with this error.

loading bundles
by Tom Elliott June 30, 2007

June 30, 2007

my bad... The Objective C project template can't know the name of the principal class when the project is set up, so naturally you have to edit the info.plist and add it later. So then the miracle is that the code does work when called with the -A flag. I guess that must be some py2app magic going on... Tom Elliott

loading bundles
by Tom Elliott June 30, 2007

June 30, 2007

Hi, I have a question about PyObjC. I used XCode to build a bundle (written in Objective C) which I then placed in the resources directory of an XCode PyObjC application and added to that project. I build the application from the command line with either of these two lines: /usr/local/bin/python setup.py py2app /usr/local/bin/python setup.py py2app -A With -A, when I load the bundle and look for the principal class it works fine: self.threadBundle = NSBundle.bundleWithPath_('Threaded.bundle') self.threadBundle.load() principalClass = self.threadBundle.principalClass() Without the -A flag, the bundle loads, but the last call returns None, and this fails also: namedClass = self.threadBundle.classNamed_('threaded') If I modify the info.plist of the Threaded.bundle to add this: NSPrincipalClass = threaded Now I can build the standalone app and it works. What's the correct way to do this? Thanks for any help. Tom Elliott

newbie: threads in PyObjC
by Tom Elliott June 27, 2007

June 27, 2007

The kill() method is just a stub, written back when I thought the way to do this is for the main thread to terminate the worker thread. Now, after more reading, I realize it's better to have the worker test a condition periodically and exit (gracefully) if necessary. The withObject_ parameter can be used to pass a reference back to the original thread. This is useful when the new thread executes a method in a different class. I ended up just calling a method in the same class, like this: from Foundation import * from AppKit import * import objc, time from PyObjCTools import NibClassBuilder class PyThreadAppDelegate(NibClassBuilder.AutoBaseClass): def init(self): self = super(PyThreadAppDelegate, self).init() return self def go_(self, sender): print 'go_' self.continueFlag = True #t = Threaded.alloc().init() NSThread.detachNewThreadSelector_toTarget_withObject_( 'newThread:', self, None) def kill_(self, sender): print 'kill_' self.continueFlag = False @objc.signature('v:@') def newThread_(sender): pool = NSAutoreleasePool.alloc().init() print 'Threaded', sender for i in range(10): if sender.continueFlag: time.sleep(1) print i del pool Thanks.

What is the error that you're getting? I cannot reproduce this on 10.4.10 with Python 2.5. Including the setup.py file you're using to build the example you included would also be helpfull. Ronald Thanks, Ronald, for taking an interest in this. The error I get is: SyntaxError: invalid syntax The terminal shows the script and points to the last brace of widget.pack() The setup.py file I'm using is: #!/usr/bin/env python """ py2app build script for MyApplication Usage: python setup.py py2app """ from distutils.core import setup setup( app=["/Users/shawnmiranda/Desktop/Label.py"], ) This same setup script works just fine with: # File: hello1.py from Tkinter import * root = Tk() w = Label(root, text="Hello, world!") w.pack() root.mainloop() Both GUI scripts work just fine from the command line.

Build Applet Environ problem...
by Jerry LeVan June 25, 2007

June 25, 2007

Hi, This weekend I got a MBP and started to transition to the Intel from PPC. I use the "Build Applet" tool to make lightweight apps that I can launch from the Dock. Some of my apps use environmental variables to simplify the environment setup. On the PPC G4 the applets would pick up the environmental variables when launched from the dock. On the Intel side this does not appear to be the case. If I launch the app from the command line "open -a" the environment vars will be picked up. Is this problem somehow my fault or is this a PythonMac/Intel problem? Jerry
