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.

Yeah, Illustrator-returned references are pretty fragile, although it's less of an issue if you create an object then apply all of your desired transformations to it before you create the next one. > Can I refere to my created objects via names (self.name)? IIRC, objects aren't named by default; however you could generate your own unique names easily enough. Assign each object a unique name via the 'make' command's 'with properties' parameter, and then use that name in any future references you construct yourself.

Path conversions
by Henning Hraban Ramm March 2, 2008

March 2, 2008

I guess this is a FAQ, but I couldn't find an answer that fits my needs... Normally you use unicode paths (with os.sep) with python. For appscript you need AppleScript file aliases (or how they're called). Additionally OSX' file system uses decomposed UTF-8, while most applications use composed UTF-8. Two different conversions that I struggle with all the time, and I'm very unhappy with my own "solutions". Up to Python 2.4 there was the macfile module (or was it part of appscript?) with its Alias object. Now it's gone. (Even if I don't know if it would fit my needs.) There's still the undocumented Carbon.File. (Would I use FSRef?) Or one could use PyObjC. (I'd like to avoid C syntax.) Or perhaps use the POSIX function from AS' StandardAdditions. (How do I call them with appscript?) And probably I overlooked some other possibilities. Please, are there any best practices to cope with OSX file paths? E.g.: I get a filename via sys.argv. It may contain international letters and spaces. It may even contain slashes if the volume was written with OS9. It might be a relative path. It's in the default encoding of the shell, or isn't it? * open that file - ok, should work without conversions. * open that file with some application via appscript -> convert the name to a valid "old style Mac path". (-> Absolute path, add volume name etc.) * write that filename into a file to be processed by e.g. TeX -> convert to composed UTF-8. * display that filename in some wxPython/dabo widget -> I still don't understand what encoding that needs, seems to differ by widget (label vs. tree view vs. status line). * other possibilities of output: print to stdout (encoding?), growl, database... Maybe I overlooked some basics of Python's Unicode handling, but my main problem at the moment are those Mac paths for appscript. Please help? Greetlings from Lake Constance!

py2app not finding twisted.protocols.amp
by Nathan Feb. 29, 2008

Feb. 29, 2008

I'm on a MacBook Pro running OS X 10.5.2 using py2app installed with the "easy" method in the py2app install docs. I'm trying to package a little pyglet+twisted (pyglet.org, twistedmatrix.com) project that I'm working on, and it _mostly_ works, except it keeps giving me the following error when I try to run the resulting app: ImportError: No module named amp Help!? I've done the following steps to try to debug the problem, with no success: * Noticed that the following imports DO work: from twisted.internet import reactor, task from twisted.internet.protocol import ClientCreator * Verified that I get the same error when running the app with the following import lines: import twisted.protocols.amp or from twisted.protocols import amp * Tried the following command-line variations without any variation in the error (although app sizes varied): python setup.py py2app --includes twisted.protocols python setup.py py2app --includes twisted.protocols.amp python setup.py py2app --use-pythonpath python setup.py py2app --use-pythonpath --include twisted.protocols.amp python setup.py py2app --use-pythonpath --include twisted.protocols.amp --graph python setup.py py2app --use-pythonpath --include twisted.protocols.amp -p twisted.protocols python setup.py py2app --use-pythonpath -p twisted.protocols python setup.py py2app --use-pythonpath -p twisted * Used the following py2applet-generated setup.py the whole time: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['running-man.py'] DATA_FILES = ['images'] OPTIONS = {'argv_emulation': True} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], ) ~ Nathan

/Library/Python/... path in MacPython
by Robin Dunn Feb. 29, 2008

Feb. 29, 2008

Has there been any discussion in the past about having MacPython also having the /Library/Python/2.5/site-packages on the default sys.path like Apple's Python does? If so, were there specific reasons for not doing it? At first blush it would certainly make it easier for package authors who want to support both ApplePython and MacPython. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters?

Python module installation on Leopard runs but doesn't install
by Robert Anderson Feb. 28, 2008

Feb. 28, 2008

I am a new user to Python on Mac (Leopard) and am having a problem installing modules. I have seen various mails about directory problems with Python Leopard and I am not sure if they relate to my particular problem. I am running a factory installation of Leopard and command line Python appears to run OK. However, when I attempted to install a downloaded package, PYTZ for example, the installation failed with a message "... requires System Python to install...". From the Python website I found the following link concerned with installing additional items, in particular IDLE: http://wiki.python.org/moin/MacPython/Leopard I followed the instructions and command line Python still works, IDLE works and the installations now appear to work, however, nothing appears to have been installed and the downloaded(?) modules cannot be imported. Can anyone provide any suggestions on what I should try next? Thanks in advance Robert Anderson

compiling PIL on OSX10.5
by DavidW Feb. 28, 2008

Feb. 28, 2008

Hello all, I'm trying to compile the image library PIL 1.1.6, using their setup.py (python 2.4 on OX10.5) and gcc (i686-apple-darwin9-gcc-4.0.1) loader is throwing a build error: ----------- building '_imagingtk' extension gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -g - bundle -undefined dynamic_lookup build/temp.macosx-10.5-fat-2.4/ _imagingtk.o build/temp.macosx-10.5-fat-2.4/Tk/tkImaging.o -L/opt/ local/lib -L/usr/local/lib -L/Library/Frameworks/Python.framework/ Versions/2.4/lib -L/usr/lib -o PIL/_imagingtk.so -framework Tcl - framework Tk ld: in /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libcrypto. 0.9.7.dylib, file is not of required architecture for architecture i386 collect2: ld returned 1 exit status ----------- which is fair enough, but- why is setup.py looking for /Developer/SDKs/ MacOSX10.4u.sdk? even though MacOSX10.5.sdk is also at Developer/SDKs/ Is there any reason to keep MacOSX10.4.sdk hanging around? I moved it out of the way and setup.py puts this together for compilation: ----------- building '_imagingmath' extension gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk - fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd - fno-common -dynamic -DNDEBUG -g -I/System/Library/Frameworks/ Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/ Headers -IlibImaging -I/opt/local/include -I/Library/Frameworks/ Python.framework/Versions/2.4/include -I/usr/local/include -I/usr/ include -I/Library/Frameworks/Python.framework/Versions/2.4/include/ python2.4 -c _imagingmath.c -o build/temp.macosx-10.5-fat-2.4/ _imagingmath.o ----------- i.e it still want to reference /Developer/SDKs/MacOSX10.4u.sdk Any clues?

Using SM2DGraphView (or any graphing utility)
by Jacob Davis Feb. 25, 2008

Feb. 25, 2008

Hi. I am looking for help namely with SM2DGraphView, but if you know another package/utility that is easy to do basic line graphing/ plotting with, that would also help. I am trying to get SM2DGraphView to work in an app I am making with Xcode and Interface Builder 3.0. I don't know pyobjc at all really, and I am somewhat new to Interface Builder. I have installed the framework and the palette. I have an app that will show the graph, but I can't figure out how to get data from my python script into the data of the SM2DGraph. I can't really understand SM2DGraphView's online documentation... I understand that I need to implement some classes and methods, but I am almost completely lost. This article on macresearch (http://www.macresearch.org/cocoa_for_scientists_part_xviii_graphing_data_wi… ) shows how to get SM2DGraphView to work using objc... if anybody can translate this so that I can just use python, that would be great. Any help is appreciated. Any push in the right direction is helpful! Thanks in advance, Jake

installing python and mysqldb
by jane doe Feb. 25, 2008

Feb. 25, 2008

Hello, You are hearing from one tired puppy. I have been wrestling with different directories, reading umpteen web pages, sifting through postings, re-installing, and re-locating, and resetting paths, and all that jazz. I think I'm partially insane now. After about 5 days solid, trying to slog through this, I'm asking for some help. Question: If I were to start all over again, which download site do you recommend? I would like to know, if there is anyone out there who knows which directory to be in, to be sure config files or directories or paths are correct, so that this will work. PLEASE!!!!!!!!! My machine is OS X 10.4, I have Python 2.3.5 or MacPython 2.4.4, Mysql 14.7, and I installed mysqldb 1.2.2 (but the contents look like they were 1.2.1?) 1000 humble Thanks....
