os 9.2
by Suresh Krishna May 21, 2010

May 21, 2010

hi, i have to work with mac OS 9.2 for legacy reasons...is there a compiled version of python for this os ? i need to get input about variable values from the user and then print out some text files that make use of this input. a gui would be nice, but keyboard based input would be ok too... thanks much, suresh ps. if there isn't a version of python that will work, perhaps you could suggest some other scripting language for 0S 9.2 ?

py2app cannot move to target thread error
by Scott Frankel Sept. 22, 2009

Sept. 22, 2009

Hello, I'm troubleshooting a PyQt-PostgreSQL py2app error: "Cannot move to target thread". Note that a test app builds and runs happily. The error only comes up when I add PyQt4.QtSql' to py2app's option includes. eg: This works: OPTIONS = {'argv_emulation': True, 'includes': ['sip', 'PyQt4._qt']} This doesn't: OPTIONS = {'argv_emulation': True, 'includes': ['sip', 'PyQt4._qt', 'PyQt4.QtSql']} Researching the error, I've set DYLD_PRINT_LIBRARIES=1 in my shell and am looking for duplicate instances of Qt libraries. I'm not seeing anything obvious. But I also don't know exactly what to look for. For example, should I be concerned with dyld output running the app or building it? I created my build environment using macports. It looks like the correct libs are being accessed. The last of the dyld output looks like this: dyld: loaded: /opt/local/libexec/qt4-mac/plugins/sqldrivers/ libqsqlpsql.bundle dyld: loaded: /opt/local/lib/postgresql83/libpq.5.dylib dyld: loaded: /opt/local/libexec/qt4-mac/lib/QtSql.framework/Versions/ 4/QtSql dyld: loaded: /opt/local/libexec/qt4-mac/lib/QtCore.framework/Versions/ 4/QtCore dyld: loaded: /opt/local/lib/libz.1.dylib dyld: loaded: /opt/local/lib/libssl.0.9.8.dylib dyld: loaded: /opt/local/lib/libcrypto.0.9.8.dylib QObject::moveToThread: Current thread (0x1d17d0) is not the object's thread (0x1a7820). Cannot move to target thread (0x1a7820) Suggestions? Thanks in advance! Scott

Can I set an environment variable with py2app?
by Christopher Barker Sept. 1, 2009

Sept. 1, 2009

Hi folks, I was using the Peppy editor, and it's spell checker relies on PyEnchant, which uses ctypes to use the enchant lib. I am using a macports enchant, so I had an environment variable set so that PyEnchant could find it: export PYENCHANT_LIBRARY_PATH=/opt/local/lib/libenchant.dylib This worked just great when I started Peppy from the command line, but when I started it from an application bundle, it failed, which I'm pretty sure is because apps started in bundles don't have the shell's environment variables. I think there is a way to set a "global" environment variable in a plist somewhere, but I think it might be better to set it in the App bundle -- is there a way to do that? For the moment, I've hacked the enchant module to look in the macports location, but I don't know if the maintainer will want to make that a permanent change. If he does, what would be the path to a fink enchant lib? we might as well add that too! -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

Oh --- and I've thought about it, but I've got no idea how to implement it as a filter or recipe. The module name is PyQt4 or PyQt4.QtGui (if specific) when scanning the macholib tree, but the QtSomething_debug only gets added when at the end PythonStandolone is called --- then the resulting files list has the QtSomething_debug files and it's already to late for a filter or anything.

Well there *is* a sip recipe, but it isn't in the __init__.py of the recipes, thus isn't really used at all. Czarek

py2app 2009-08-31 dSYM fix patch
by Cezary Krzyżanowski Aug. 31, 2009

Aug. 31, 2009

Hi! The newest greatest and finest py2app from SVN has two bugs for which I'm supplying a patch: * it uses shutils, which it does not import * the dSYM removal function really does delete given files, but the list of files to strip isn't updated, which fails on trying to strip an non-existing file BTW --- I'd love a postscript hook.

Hello.
by Lawrence Anderson Aug. 30, 2009

Aug. 30, 2009

Hi, My name is Lawrence and Im an undergraduate at Indiana State University. I always grew up loving technology and computers so I decided to pursue my degree in Information Technology. Im taking my first Programming class ever. My goals are to own various web successful web businesses and to be a proficient web developer. I just purchased a Macbook Pro for the school year and plan on building a PC for next semester. Im getting the hang of this Mac but it is still fairly new to me. My class is to begin programming in Python, but our teacher doesn't speak very good english so she wasn't able to convey her point very well to the rest of the class. I find that this may be a problem later down the road, so I took the liberty of finding out how to open Python on my Mac. I got to the terminal through the utility folder and I also downloaded Aquamacs Emacs as a code editor. Im a diligent worker so I love to get through obstacles, but Im not afraid to ask questions as they come up. In technology the computer is the one who works alone, not the people. Any starting help would be appreciated. Thank you, Lawrence

The aem and appscript modules are 64-bit clean. The osax module will only work on 64-bit if you use static glues instead of fetching terminology dynamically. aemreceive's sfba module is 32-bit only; the rest should work on 64-bit, though hasn't been tested. > Looking at the aemreceive documentation, it appears all the hooks > are there to do this, although this particular Apple Event isn't > illustrated in the documentation, nor have I found sample code for > this.

Work through the tutorials, and if it's still not clear then ask. If you plan on implementing an AEOM, look into Cocoa Scripting - it's a bit of a clunker (and has been since 10.2), but it's better than nothing.

aemreceive/py-appscript and 64-bit
by Kevin Walzer Aug. 25, 2009

Aug. 25, 2009

I've moved my Python work to a four-way universal build of 2.6 .1 (64 & 32 bit for PPC and x86). Do py-appscript and aemreceive work under 64-bit? It's not quite clear to me because they have some dependencies on Carbon, and I'm not sure how Carbon works with a 64-bit build of Python. What I'm actually interested in is using aemreceive to implement a "do script" Apple event for Python, in which a Python app could receive a "do script" command via AppleScript that would execute arbitrary Python code. This functionality is based on the 'dosc' Apple Event constant, and is part of Terminal's AppleScript dictionary (for shell commands); Tk-Aqua also implements similar functionality that allows an app to execute Tcl code. Looking at the aemreceive documentation, it appears all the hooks are there to do this, although this particular Apple Event isn't illustrated in the documentation, nor have I found sample code for this. Any advice is appreciated, and if I'm successful in implementing something like this, I'll post the sample code somewhere. --Kevin -- Kevin Walzer Code by Kevin http://www.codebykevin.com

py2app & multiple executable files with a main launcher
by Gabriel Rossetti Aug. 24, 2009

Aug. 24, 2009

Hello, I am trying to bundle an application I wrote usinf py2app. The application has a launcher "launcher.py" and a Python script "main.py" that calls the launcher several times in sub-processes with diff args. I successfully did this with py2exe for windows. I had py2exe generate "launcher.exe" and "main.exe" and when I run "main.exe" it does what it's supposed to correctly. I can't get this to work with py2app though. it won't allow me to generate several executable files. Does anyone know how to do this or have a better idea? I have to run multiple sub programmes in parallel but I'd like to only have one entry-point (the user just needs to click on one file) to run it. Thanks, Gabriel
