Re: [Pythonmac-SIG] newbie Mac switcher trying to set up django on Intel MacBook Pro Tiger
by Ronald Oussoren June 17, 2008

Now that there are several people that want to support Apple's build of python: how do we go forward from here? I think we should start a small project for "MacPython Addons", this project will install: * Hotfix for distutils to ensure that distutils builds univeral binaries (32-bit only at first) * (possibly) hotfix to ensure that you can install '-fat-' eggs on 10.5 * /Applications/Python-2.5/IDLE.app In there future we could add other changes, such as a 'python64' command for running python in 64-bit code. IMHO this should be done only when we have patches python.org tree that enable 4-way universal builds on Leopard, otherwise we'd have a real risk of loosing these changes in a future version.

py2app and matplotlib
by Christopher Barker May 1, 2008

May 1, 2008

Hi all, I'm having trouble getting py2app to work with matplotlib. There is a matplotlib recipe, but it's out of date, and some things have changed. The first error I got was not being able to find pytz.zoneinfo. As that's in a different place now, I commented it out of the matplotlib.py recipe. However, now I'm getting an error that I don't even know how to begin to solve: ... File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 106, in load_header hdr = MachOHeader(self, fh, offset, size, magic, hdr, endian) File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 146, in __init__ self.load(fh) File "build/bdist.macosx-10.3-fat/egg/macholib/MachO.py", line 178, in load raise ValueError("Unknown load command: %d" % (cmd_load.cmd,)) ValueError: Unknown load command: 27 > /Users/cbarker/HAZMAT/SmallToolsSVN/phCalculator/trunk/build/bdist.macosx-10.3-fat/egg/macholib/MachO.py(178)load() Enclosed is about the simplest matplotlib script, and a test_setup script to py2app it -- anyone have any ideas? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Trouble with py2app not building standalone on 10.5 Leopard
by Derrick Hendricks April 1, 2008

April 1, 2008

I am using py2app 0.3.6 installed using easy install on my 10.5 Leopard distribution. I am trying to package a piece of software into a completely stand alone app so I can distribute it to other mac users. Currently, I'm using 10.5Leopard and am not having much luck. When creating this app, the python that gets added to the Contents/MacOS is a link to: /System/Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python While this will work for just about all stock 10.5 computers, this will not work for anything that doesn't have python 2.5 installed, and I need to package this for 10.3 and 10.4 for both PPC and i386 also, and these machines do not have python 2.5 unless they were added later. I did not use the -s switch that is supposed to create a semi-standalone app and I did not tell it to skip macholib. Also, I have run the macho_standalone separately and that has not yielded any better results. Simply copying the python interpreter into the directory doesn't work either as it fails with a module traceback not found error. What I need is a way to completely include the interpreter and everything that it needs into the app bundle. Any help on this matter is appreciated.

expat.py broken in Python 2.5
by Stewart Midwinter March 30, 2008

March 30, 2008

In the lastest python 2.5 build for Macintosh, the pyexpat module binary is not available to Mac users with Intel processors. If you try to import it, you get an error saying that the binary is for PPC architecture only. This is a bug introduced in Python 2.5, since it does not exist in Python 2.4. How can we go about fixing this? File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/_xmlplus/parsers/expat.py", line 4, in <module> from pyexpat import * ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/_xmlplus/parsers/pyexpat.so, 2): no suitable image found. Did find: /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/_xmlplus/parsers/pyexpat.so: mach-o, but wrong architecture thanks S

[Help] Where is objc (PyObjc) in Leopard?
by Dongpyo Hong March 29, 2008

March 29, 2008

Dear all, I need some explanation why it is that. A few days ago, I downloaded python 2.5.2 for Mac OS X, and installed it. It goes to /Library/Frameworks/.... And I found that Leopard already had one 2.5.1 in /System/Library/Frameworks/... I didn't want to have both, thus I replaced python.framework folder in /System with python.framework fold in /Library/ It did work well until I imported objc or kinds of things. It cannot import them at all. Anyway, now I reinstalled Leopard again :-( Yes, it works fine. It can import objc and so on. Where are they in Leopard? and it is not possible to use objc with new version of python. Still I found not found objc in Leopard. Anyone can explain this?

ASTranslate and appscript question
by Robert Pyle March 28, 2008

March 28, 2008

Hi, From a python program, I'm trying to set the input and output gains of a USB audio interface (M-Audio Transit). Using ASTranslate, I've been able to write appscript code to manipulate the "Sound" preference panel of "System Preferences" to find and make note of the current sound input and output devices, select the Transit as the default device, and then restore the prior default device (which may or may not be the Transit). What I can't do so far is figure out how to set the gain while the Transit is selected. When the Transit is the selected default device, this AppleScript sets the gains as I want: --------- tell application "Finder" set volume output volume 100 set volume input volume 35 end tell --------- which ASTranslate renders as: --------- Untranslated event 'aevtstvl' Untranslated event 'ascrgdut' Untranslated event 'aevtstvl' Untranslated event 'aevtstvl' --------- Running the AppleScript twice in a row gives only two 'aevtstvl' events (I'm guessing the last two), without the 'ascrgdut'. Can anyone help me to produce appropriate appscript code? Examples? Documentation? (I've looked at everything I can find.) Thanks. Bob Pyle

ASTranslate only translates application commands; scripting addition commands aren't currently supported. You'll need to export the Standard Additions dictionary using ASDictionary and translate the original AppleScript commands yourself. Anyway, the following code should work (you don't need to target the Finder for this, btw; the current process will do fine): import osax sa = osax.ScriptingAddition() sa.set_volume(output_volume=100) sa.set_volume(input_volume=35) HTH has -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net

Sending files to the trash
by Alex MacCaw March 28, 2008

March 28, 2008

I'm making a cross platform script that sends files to the trash (or recycle bin), but am having trouble with the applescript version: Here's the applescript which I'm trying to generate: tell application "Finder" move path to the trash end tell And the py-appscript version (which doesn't work): app('Finder').move(os.path.abspath(path), to=k.trash) Can anyone give me any pointers on how to get the appscript version working?

Couple of things: - The 'to' argument should be a reference, not a constant. - Finder expects an HFS path string, alias object, or Finder reference. Python uses POSIX path strings. Example solution: from appscript import * import mactypes f = mactypes.Alias(os.path.abspath(path)) app('Finder').move(f, to=app.trash) If you're new to appscript but familiar with AppleScript, ASTranslate can provide helpful hints when translating AppleScript commands to their appscript equivalents: http://appscript.sourceforge.net/tools.html HTH has -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net

Import AppKit (pyobjc) and Cocoa-Python Debug Error
by Dongpyo Hong March 28, 2008

March 28, 2008

Hi all, I am not sure whether this issue was already dealt in here. XCode 3.0 already included python 2.5.1 (I think), and I updated it with 2.5.2 and replaced the installed one with this. Anyway, I couldn't import AppKit and relevant ones from the terminal. In XCode 3.0, when I debug project file (just I used template), it says Xcode could not locate source file: pythonrun.c (line: 851) ... What did I do wrong?
