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

MacPython wiki "moved" to Python wiki - now it's your turn...
by skip＠pobox.com March 30, 2007

March 30, 2007

After much wailing and gnashing of teeth the past couple of days, I managed to move (most of?) the content from the MacPython wiki to the main Python wiki (*). All pages were created as subpages of http://wiki.python.or/moin/MacPython The motivation for this rather hasty move was that the MacPython wiki was running an ancient version of MoinMoin and got spammed heavily. Because of its age and vulnerability it was simply too hard to keep up with all the wiki spammers. So I moved everything. I did very little to try and fix up link references. Moin's subpage references have always befuddled me, and many of the page references were weirded out to begin with, so there you have it: royal link spaghetti. This is where you come in. You can do any number of things to try to identify and fix problems: * Visit http://wiki.python.org/moin/OrphanedPages and see if there are any MacPython/... pages which are orphaned (hint: there are quite a few). Then see if you can find an incorrect link which should refer to the orphaned page. * Visit the MacPython pages. Just do a title search for "MacPython" to locate them. Visit and clean up as appropriate. * Everything got pushed down, even home pages. One of three things can reasonably be done: 1. Move a home page up if there isn't one at the top level. 2. Replace an uplevel home page with the MacPython version if the latter is "better". 3. Merge the content from the MacPython version into the uplevel home page. Instead of performing #2 and #3 yourself, you might send an email to the person and ask them to do the merge/replace. In any case, this operation is likely to require some link fiddling. * There may also be non-homepage pages at the top level which should be merged with or replaced by (or replace) the MacPython version. VisualPython comes to mind. Use your judgement * There are lots of unprotected path references in the content, e.g. /System/Library sitting there looking like a link when it should probably be {{{/System/Library}}}. * There may still be a bit of spam lurking in the pages. I tried to eliminate all the crap, but I might have missed some. * Many pages could use Category references. There are lots of pages referring to scripting specific Mac applications, home pages and many code samples. Adding CategoryMac or CategoryAppScript might be reasonable as well. * Use your WikiImagination. There are probably lots of other things that can be done. I think the MacPython wiki had fallen into a bit of disrepair, even if you ignore the spam problem, so a little general TLC would probably help. Skip (*) Thank goodness for Emacs and Mozex...

XCode fails to see py2app
by Dennis Ng March 20, 2007

March 20, 2007

Dear all, Following the examples http://developer.apple.com/cocoa/pyobjc.html as well as using PyObjC 1.4 installer for (Universal) Python 2.4 on Mac OS X 10.4 I have got an error message that Xcode cannot find py2app. There is a thread on this topic but there is no answer on how to deal with it. So I raised it again. It seems that it is a common problem to newbie and for newly installed environment. It is noted if one run the source manually i.e. follow the instruction using Xcode, interface builder, drop to terminal and do the python setup.py py2app The program will works but if you compile it under Xcode, it cannot: The details is as below and you may note that somehow Xcode can only points to the Java and nothing Python in the compile environment: Building target “Development” of project “PyAverager” with configuration “Development” — (1 error) cd / setenv ACTION setenv APPLE_INTERNAL_DEVELOPER_DIR /AppleInternal/Developer setenv APPLE_INTERNAL_DIR /AppleInternal setenv APPLE_INTERNAL_DOCUMENTATION_DIR /AppleInternal/ Documentation setenv APPLE_INTERNAL_LIBRARY_DIR /AppleInternal/Library setenv APPLE_INTERNAL_TOOLS /AppleInternal/Developer/Tools setenv BUILD_COMPONENTS "headers build" setenv BUILD_DIR "/Users/testuser/Desktop/pyObjC -

Somehow the setup script cannot find the two libraries pyobjC installed and seems to use Java environment. Any hint? Best regards. Dennis

How to make 2 scripts in one application
by Chris Van Bael March 5, 2007

March 5, 2007

Hi all, Maybe a totally noob question, but I'll ask it anyway since I couldn't find an answer on the series of tubes... I'm working on a pygame program that runs on Linux, Windows and Mac. It uses an database which it accesses through SQLAlchemy. So on Linux in setup.py we have a section to install the program and create that database. Now on Windows with py2exe I have a setup.py which has a console and a windows script. The windows script runs the program and the console script sets up the database. Since I use no library.zip file, this can also access the SQLAlchemy modules. Now I want to do something similar to that for OSX. I cannot run the script with the python installed on OSX because it needs SQLAlchemy. But the modules I need are somewhere in the application bundle, can I use them somehow? Greets, Chris

Confused about framework build
by Kent Johnson Feb. 28, 2007

Feb. 28, 2007

Hi, I am coming to Mac Python development after several years on Windows and I am a bit confused by the Python framework stuff. I have installed the framework build of Python 2.4 from pythonmac.org. Questions: - How can I have Python 2.4 and 2.5 both available? I am developing a web site that will be deployed under 2.4 but I would like to have 2.5 available for other use. pythonmac.org says, "framework builds of the same thing do not coexist peacefully." What is the problem with installing multiple framework builds? Can I install the MacPorts version of Python 2.5 (for command line use) instead? - Do I have to install the pythonmac version of add-on libraries? For example pythonmac has pysqlite2 version 2.2.2 but MacPorts has version 2.3.3; can I install the more recent MacPorts version and use it with the framework build? Similarly MacPorts has a more recent version of psycopg. Any help or pointers to help gratefully accepted. Thanks, Kent

pygame/wx not playing on MacOSX
by Jon Peirce Feb. 26, 2007

Feb. 26, 2007

I have a cross-platform wx application that needs to run some graphics routines in pygame. On Mac (but not windows) when I close the pygame window the wx application quits. The only way I've found to get around this is to run the pygame part of the application using wx.Process_Open but this creates a new instance of python which I also don't want (because of python startup/import times). I've attached a minimal script to show the problem. On win32 you can click the 'run' icon as many times as you like and get a pygame window each time. On my mac it runs once then gives the bouncy ball and dies with the message; objc: FREED(id): message release sent to freed object=0x7381cb0 Trace/BPT trap Full info is in the crashlog also provided. I'm running framework python 2.4, with wxPython2.6 (and tried 2.8) and pygame1.8.0pre on a G5 PPC OSX 10.4 Does anyone know how to launch pygame/wx safely together? cheers Jon This message has been checked for viruses but the contents of an attachment may still contain software viruses, which could damage your computer system: you are advised to perform your own checks.

Dock tile icon
by Amrit Jassal Feb. 23, 2007

Feb. 23, 2007

In my py2app built application, I want to replace the standard application dock tile icon with my own icon. After using the --iconfile option with py2app, I see that the icon file (icns) is copied into Contents/Resources but Info.plist (CFBundleIconFile) does not reference this icon file. Manually updating the plist also has no effect on the dock icon. Where did I go wrong? I am using python 2.4.4 on OS X 10.4.8 Thanks
