PySight
by Dethe Elza July 13, 2005

July 13, 2005

Hi folks, I'm looking for advice about packaging a library. Jonathan Wight of Toxic Software has built a simple framework around SequenceGrabber to expose it to Cocoa. I've made a trivial PyObjC wrapper and tested it sucessfully with Python. I'd like to build a disk image that contains a) an installer for the framework + wrapper, b) sample apps (Cocoa and Python versions of the same program), and c) the source code to all of these. Does this sound like a good idea, or should I separate it out into multiple .dmg files? Finally, I haven't really used the bdist_mpkg command to build an installer (except for running it on the PyObjC trunk periodically). All I'm installing is a framework and an __init__.py file. Is bdist_mpkg the way to go? TIA --Dethe

appscript + iPhoto problem
by Gábor Farkas July 13, 2005

July 13, 2005

hi, what i want to achieve is the following. i want to find a photo in iphoto (i can do that), and then assign some keywords to it. i can find the photo with: iphoto = appscript.app('iPhoto') photos = iphoto.photos() and then i find my photo in 'photos'. and i can also list it's keywords. but how should i SET the keywords? i tried to call the 'help()' method on those objects, but all i get are properties, and i can't find a way to set them. so where should i look? gabor

Zope.Interface won't build on 10.4
by brad.allen＠omsdal.com July 13, 2005

July 13, 2005

Maybe I should take this to one of the Twisted or Zope lists, but this appears to be a Mac-specific issue so I thought it worth mentioning here. The problem is that Zope Interface 3.01 won't build on Mac OS 10.3 using either the stock Python 2.3 or Python 2.4.1 (error transcript at the bottom). A Google search of the problem turned up a discussion on one of the Zope lists about this, but I didn't understand how to implement the suggested solution. One message in the thread suggests the problem is that Python was compiled under gcc 3.x and Mac OS 10.4 defaults to using gcc 4.x, and that using gcc select can fix the problem. Any thoughts on how to do that? http://mail.zope.org/pipermail/zope3-users/2005-June/000725.html Here is the error transcript. A similar error happens when running setup.py install. oms-ballen:~/Desktop/TwistedSumo-2005-05-25/ZopeInterface-3.0.1 ballen$ sudo python setup.py build Password: running build running build_py running build_ext building 'zope.interface._zope_interface_coptimizations' extension gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd -fno-common -dynamic -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -IDependencies/zope.interface-ZopeInterface-3.0.1/zope.interface -I/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3 -c Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/_zope_interface_coptimizations.c -o build/temp.darwin-8.1.0-Power_Macintosh-2.3/Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/_zope_interface_coptimizations.o Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/_zope_interface_coptimizations.c:339: error: static declaration of 'SpecType' follows non-static declaration Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/_zope_interface_coptimizations.c:73: error: previous declaration of 'SpecType' was here error: command 'gcc' failed with exit status 1

pyui font troubles
by David Hill July 12, 2005

July 12, 2005

Hi, I'm relatively new to Python and I'm trying to work through some examples in Sean Riley's "Game Programming with Python" book. Unfortunately, I'm having some trouble with most of the examples that use his pyui library. It looks like the examples fail when trying to create a font object for the arial font. I took a look in the pyui code that creates the font (using pygame) and it has this suspicious line: > faceFile = os.environ['WINDIR'] + "/Fonts/" + fontRegistery[faceFile] where fontRegistery[faceFile] == "arial.ttf" That didn't fill me with a great deal of confidence (since it produces a KeyError exception on WINDIR), so I tried a quick hack: > if os.environ.has_key( 'WINDIR' ): > faceFile = os.environ['WINDIR'] + "/Fonts/" + > fontRegistery[faceFile] > else: > faceFile = "/Library/Fonts/Arial" That gets me the bus error shown below. Clearly, the font format on Mac OS X isn't what pygame is expecting. Has anybody else had any luck getting the code from this book to work? The error in the console looks like this: > davidh% /usr/local/bin/pythonw terrainView.py > Creating font: arial > {'impact': 'impact.ttf', 'arial': 'arial.ttf', 'courier': > 'cour.ttf', 'courier new': 'cour.ttf', 'times': 'times.ttf', 'comic > sans ms': 'comic.ttf', 'times new roman': 'times.ttf'} arial > Fatal Python error: (pygame parachute) Bus Error > Abort The stack crawl from the crash report looks like this: > Exception: EXC_BAD_ACCESS (0x0001) > Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000 > > Thread 0 Crashed: > 0 font.so 0x007bb464 initfont + 4972 > 1 org.python.python 0x10052e38 type_call + 284 > (typeobject.c:435) > 2 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 3 org.python.python 0x1007c9e4 do_call + 136 (ceval.c: > 3755) > 4 org.python.python 0x1007c6dc call_function + 1068 > (ceval.c:3572) > 5 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 6 org.python.python 0x1007b284 PyEval_EvalCodeEx + > 2152 (ceval.c:2730) > 7 org.python.python 0x10026274 function_call + 344 > (funcobject.c:548) > 8 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 9 org.python.python 0x10015a88 instancemethod_call + > 796 (classobject.c:2432) > 10 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 11 org.python.python 0x1007c26c > PyEval_CallObjectWithKeywords + 256 (ceval.c:3420) > 12 org.python.python 0x1000eddc PyInstance_New + 320 > (classobject.c:576) > 13 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 14 org.python.python 0x1007c9e4 do_call + 136 (ceval.c: > 3755) > 15 org.python.python 0x1007c6dc call_function + 1068 > (ceval.c:3572) > 16 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 17 org.python.python 0x1007c83c fast_function + 212 > (ceval.c:3631) > 18 org.python.python 0x1007c6c4 call_function + 1044 > (ceval.c:3568) > 19 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 20 org.python.python 0x1007b284 PyEval_EvalCodeEx + > 2152 (ceval.c:2730) > 21 org.python.python 0x10026274 function_call + 344 > (funcobject.c:548) > 22 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 23 org.python.python 0x10015a88 instancemethod_call + > 796 (classobject.c:2432) > 24 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 25 org.python.python 0x1007c9e4 do_call + 136 (ceval.c: > 3755) > 26 org.python.python 0x1007c6dc call_function + 1068 > (ceval.c:3572) > 27 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 28 org.python.python 0x1007b284 PyEval_EvalCodeEx + > 2152 (ceval.c:2730) > 29 org.python.python 0x10026274 function_call + 344 > (funcobject.c:548) > 30 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 31 org.python.python 0x10015a88 instancemethod_call + > 796 (classobject.c:2432) > 32 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 33 org.python.python 0x1007c26c > PyEval_CallObjectWithKeywords + 256 (ceval.c:3420) > 34 org.python.python 0x1000eddc PyInstance_New + 320 > (classobject.c:576) > 35 org.python.python 0x1000c348 PyObject_Call + 48 > (abstract.c:1752) > 36 org.python.python 0x1007c9e4 do_call + 136 (ceval.c: > 3755) > 37 org.python.python 0x1007c6dc call_function + 1068 > (ceval.c:3572) > 38 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 39 org.python.python 0x1007b284 PyEval_EvalCodeEx + > 2152 (ceval.c:2730) > 40 org.python.python 0x1007c8cc fast_function + 356 > (ceval.c:3644) > 41 org.python.python 0x1007c6c4 call_function + 1044 > (ceval.c:3568) > 42 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 43 org.python.python 0x1007c83c fast_function + 212 > (ceval.c:3631) > 44 org.python.python 0x1007c6c4 call_function + 1044 > (ceval.c:3568) > 45 org.python.python 0x1007a140 PyEval_EvalFrame + > 8888 (ceval.c:2163) > 46 org.python.python 0x1007b284 PyEval_EvalCodeEx + > 2152 (ceval.c:2730) > 47 org.python.python 0x1007e678 PyEval_EvalCode + 48 > (ceval.c:484) > 48 org.python.python 0x100b2ee0 run_node + 76 > (pythonrun.c:1265) > 49 org.python.python 0x100b266c > PyRun_SimpleFileExFlags + 592 (pythonrun.c:863) > 50 org.python.python 0x100bf640 Py_Main + 2596 (main.c: > 484) > 51 org.python.python 0x000018d0 0x1000 + 2256 > 52 dyld 0x8fe01048 _dyld_start + 60 Does anybody have any ideas or suggestions?

Building a multi-component application with py2app
by dfh＠forestfield.co.uk July 12, 2005

July 12, 2005

I have a wxPython application where the main process has a number of components that can be started as separate processes when required, for example, an independent GUI help viewer and several console-type helper tasks. With py2exe under MSW I can build them all into the same 'Dist' with a single setup.py so they share the same support modules and libraries. Is the same thing achievable with py2app? I can obviously build each component as a separate application, with no sharing, but the overhead is 10+ Mb per component. The py2app examples for drpython imply that the 'app' parameter in the call to setup can be a list of .pyw(?) files but when I try something similar, I get "error: Multiple targets not currently supported". Is it possible to achieve this, or maybe to 'merge' a number of standalone apps? Regards, David Hughes Forestfield Software

py2app and Python 2.3.5
by João Leão July 12, 2005

July 12, 2005

I have both Apple's Python (2.3.5) and MacPython 2.4.1 installed under 10.4.1. Before Tiger (Panther + Python 2.3 with Panther addons) i had been using py2applet to build an application that makes extensive use of CoreGraphics. As previously noted by others, this module isn't available through Python 2.4, so my question is: How do I tell py2app to build an application using the vendor Python 2.3.5 (embedded or not) instead of Python2.4? Can it be done with py2applet? Thanks in advance, joão

where is PyInterpreterView
by David Cairns July 12, 2005

July 12, 2005

Hi everybody, At WWDC, I saw the Python in OS X talk, and I am really interested in integrating PyInterpreterView in my application, in order to implement a sort of scripting/debugging system, but I can't seem to find the .palette file the widget is contained in. Is this something else I need to download and/or install ? Also, how would i go about setting up my application so that the PyInterpreterView would be able to access my application's globals? Any help is greatly appreciated. -- david

open() does'nt work with py2app
by Mathieu Renauld July 12, 2005

July 12, 2005

Hi! First forgive me for the language mistakes (I'm french)!! I try to make a program using wxPython and Python 2.4. There's a function which creates a file like that: file = open('myfile.py','w') when I launch the program from a shell (python test.py), it work perfectly and the file is created, but once I've 'compiled' it with py2app, the created app doesn't create anything. If somebody has already met that problem, please help me !! thanks!

Tiger's default Python set-up
by Dave Stokes July 11, 2005

July 11, 2005

Hello, all. this is my first post to the pythonmac-sig mailing list, so please forgive me if my question is not fully in line with the purpose of the group. Anyway, could someone provide me with some information about how Python is supposed to be set up under Mac OS 10.4? Specifically, what would a clean system install look like? I had some difficulty with Python after upgrading from 10.3 which I attempted to repair myself. I realize now, after looking over the system and doing some research on-line, that I had no idea what I was doing - the majority of Python work I'd done had been either under Windows or Linux, so trying to apply that knowledge to my Mac installation ended up completely breaking things. Every Python shell/IDE is running a different version, and none of them can 'see' my site-packages directories (of which there are four in various locations). Everything I've subjected my poor machine to has just made it worse, so I've come to the conclusion that I should just chuck it and start over. Can anyone offer any advice? Environment variables, directory structure, et cetera. I'd appreciate it. Thanks, Dave Stokes

appscript raises deprecation warning for macerrors
by brad.allen＠omsdal.com July 11, 2005

July 11, 2005

I just started using appscript for the first time (it's great!), and ran across this deprecation warning when I import appscript. It looks like the problem is not with appscript itself but with the macerrors module that it utilizes. I'm using appscript with Tiger's built-in Python, because that's what the appscript installer defaults to using. (I don't think the Python 2.4 version is available yet). Maybe this isn't news to anyone, but just in case, here is the message. Python 2.3.5 (#1, Mar 20 2005, 20:38:20) [GCC 3.3 20030304 (Apple Computer, Inc. build 1809)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> from appscript import * /System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/aem/send/errors.py:5: DeprecationWarning: Non-ASCII character '\x80' in file /System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/macerrors.py on line 326, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details import macerrors >>> To make this message go away, I had to open up macerrors.py and get rid of the non-ASCII characters. It turns out those characters were in the comments, not the actual code. There were a number of them, so to save time I ended up doing a Select All in BBEdit and chose Text-> Convert to ASCII.
