ascii <-> unicode <-> cocoa NSString
by Keith Ray Feb. 20, 2006

Feb. 20, 2006

PyFIT gives me ascii strings,and I am trying to call cocoa (and eventually some applescript) functions from Python. I tried from Foundation import NSString from AppKit import NSWorkspace import os.path ....etc... ws = NSWorkspace.sharedWorkspace() uapplicationpath = unicode(self.applicationpath, 'ascii') self.launchsuccess = ws.launchApplication_( NSString.stringWithString_(uapplicationpath) ) but get a traceback: line 23, in result uapplicationpath = unicode(self.applicationpath, 'ascii') TypeError: decoding Unicode is not supported Help ?

Fwd: python help
by Nehemiah Dacres Feb. 20, 2006

Feb. 20, 2006

Dear Python Help Group I am a student of Computer Science and i need help understanding how MacOS 10.4 (tiger) handles Python. the class I am in is "Intro to Object Oriented Programing" so they teach in python to reduce teaching of syntax so they can focus on O. Orientation. I need to import modules we create in class into my programs and i want to be able to do this as painlessly as possible per run. My first solution was to find where all the other third party modules are kept so i found "PyObjC" and there i found how to install the modules i needed for class. I got this to work and the terminal agreed, i ran homework from the terminal that day and they worked well. However lately I've been having problems. every sence then, ive been getting this error 'import site' failed; use -v for traceback 'import site' failed; use -v for traceback 'import site' failed; use -v for traceback Could not find platform independent libraries <prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] 'import site' failed; use -v for traceback and I really don't know what's going on. I know what PATH is and how to append it but my knowledge of unix stops at your tutorials in the tiger terminal, and that of Inside Mac (I never even got Fink and those X Droplets to work ) so I don't want to mess things up further than I already have. Recently (im certian it was a later date than when i changed that) Bittorrent stopped working. I ran it from withing the package and got this Last login: Thu Feb 16 20:52:55 on ttyp2 /Users/Username/Applications/BitTorrent.app/Contents/MacOS/BitTorrent; exit Welcome to Darwin! adsl-70-130-208-110:~ Username$ /Users/Username/Applications/BitTorrent.app/Contents/MacOS/BitTorrent; exit Could not find platform independent libraries <prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] 'import site' failed; use -v for traceback Traceback (most recent call last): File "/Users/Username/Applications/BitTorrent.app/Contents/Resources/__main__.py", line 1, in ? import AppHelper File "./AppHelper.py", line 14, in ?

See console for errors. Trace/BPT trap logout [Process completed] Most of that was greek to me but upon looking at the explanation the problem was clearly my python. (which was made even more obvious when looking at the resources folder: it seems Bittorent is a Python native app). This makes things even more dire because I've been using that program for my anime fix, it doesn't work for ANY account on the machine. the final change is that i found the location of the path in Extras.pth (/System/Library/Frameworks/Python.framework/Versions/2.3/Extras/lib/python2.3) found that the last folder was just "python" instead of "python2.3" but after I remedied that, it still didn't work the situation is pretty bad but at least regular scripts work ( n=raw_input('enter the number up to which you want to take the product') n=int(n) k=raw_input('enter the number u want to skip') k=int(k) prod=1 for i in range (1,n+1,k): prod*=i print i print prod ) once with TextWrangler The terminal told me that it couldn't find the debugger file. i just found the file dbg.py and put it were the terminal said it was looking, and sence then i haven't gotten that message. Thank you, for your help python Student

Hi there, The version of My Mac is Mac OX 10.4.4; I guess that Python 2.3.5 came with the Mac OX10.4.4 I wanted to install Python 2.4.2; It worked fine till "Make Install". After I reentered the terminal, I still saw Python 2.3.5 instead of 2.4.2. Ver confused...

add other Python distros to the downloads page?
by Bill Janssen Feb. 16, 2006

Feb. 16, 2006

I was thinking of adding a section at the bottom with pointers to the ActiveState Python along with the fink and DarwinPorts Python downloads. Are there others we might mention? Isn't there a big SciPy installer, too. Bill

Getting Terminal input and output encoding
by Nir Soffer Feb. 16, 2006

Feb. 16, 2006

I'm trying to find a way to get the user encoding used for example for command line arguments e.g.: # creating an Hebrew file name... touch �� ./foo.py * From my experience with Mac OS X 10.0-3, I know the foo.py will always get hebrew-name using utf-8. You can also see this when you type non-ASCII in the Terminal: $ touch \327\242\327\221\327\250\327\231\327\252 Will create the file named "��" I noticed that it does not matter what encoding you set in the Terminal window setting, anything you type will use utf-8 encoding. Anyway, I could not find any documentation about this issue, expect this: "All BSD system functions expect their string parameters to be in UTF-8 encoding and nothing else. Code that calls BSD system routines should ensure that the contents of all const *char parameters are in canonical UTF-8 encoding." <http://developer.apple.com/documentation/MacOSX/Conceptual/ BPInternational/Articles/FileEncodings.html#//apple_ref/doc/uid/ 20002137-DontLinkElementID_4> On Linux people are getting the encoding with: import locale locale.getpreferredencoding() But on OS X getpreferredencoding() returns useless results, at least for decoding command line arguments or printing readable output. For example: 1. Choose "Window Settings..." in the Terminal and set the Character Set Encoding to Unicode (UTF-8) 2. Try: >>> import locale >>> locale.getpreferredencoding() 'mac-roman' I have found this code trying to correct the behavior (from bzrlib): # work around egregious python 2.4 bug >>> import sys >>> sys.platform = 'posix' >>> import locale >>> locale.getpreferredencoding() 'US-ASCII' >>> sys.platform = 'darwin' Obviously this workaround does not work around this problem :-) So my conclusion is that Mac OS X uses always utf-8 for input to the shell. Unless I am missing something? Next, how can you get the Terminal output encoding? For example, what if a user changed the Character Set Encoding to Western (Mac OS Roman) - how can you detect this setting from Python? Best Regards, Nir Soffer

Build script for Universal Python
by Ronald Oussoren Feb. 15, 2006

Feb. 15, 2006

Bob, The attached patch replaces the script in Mac/OSX/Dist by a python script that builds a "batteries included" universal binary. The attached background.jpg should be placed in Mac/OSX/Dist/resources (and hopefully someone donates a nicer image). Due to lack of time I haven't tested the installer and contained binaries yet. Things that should be fixed: 1. 'make frameworkinstall' will no longer install files in /usr/local/ bin. 2. the postflight script should be rewritten, it creates a shellscript version of pythonw 3. the package is a ".pkg" instead of an ".mpkg". This should make it possible to create an installer that is truely "batteries included" in the future. 4. the package doesn't update user profiles (should be an optional .pkg in the .mpkg). 5. there's still 'python' and 'pythonw' that behave differently, python should be replaced by pythonw and pythonw should be a symlink to python for backward compatibility. 6. A patch for distutils that allows compiling on 10.3.9 7. A patch for distutils that recognizes '-arch' and '-isysroot' in extra_compile_args and extra_link_args and removes those flags from CFLAGS/LDFLAGS 8. The Python documentation is no longer installed as a help book. What definitely should be tested: 1. Run 'regrtest -uall' on 10.3.9(PPC), 10.4.4(PPC) and 10.4.4(Intel) 2. Try to use existing 10.3 packages with this build, especially C++ ones. Ronald

Pythonw and VPython and Fink
by Matthias Milczynski Feb. 15, 2006

Feb. 15, 2006

Hello, I would like to use SPE (cool Python editor) with vpython, that I installed with fink (unfortunately there is no other possibility yet). My vpython stuff is located in /sw/lib/python2.4/site-packages/ visual, but I run SPE with /usr/local/bin/pythonw2.4. When I try to run any vpython script I encounter the following error: /////////////////////////////////////////////////////////////// Traceback (most recent call last): File "bounce.py", line 1, in ? from visual import * File "/sw/lib/python2.4/site-packages/visual/__init__.py", line 15, in ? import array_backend File "/sw/lib/python2.4/site-packages/visual/array_backend.py", line 1, in ? import cvisual ImportError: Failure linking new module: /sw/lib/python2.4/site- packages/cvisualmodule.so: Symbol not found: _PyObject_IsInstance Referenced from: /sw/lib/python2.4/site-packages/cvisualmodule.so Expected in: /Library/Frameworks/Python.framework/Versions/2.4/ Resources/Python.app/Contents/MacOS/Python /////////////////////////////////////////////////////////////// I assume that the solution of this problem would be to somehow get a fink-based pythonw, but this seems to be not avaiable. Can anybody help me with this? Thanks a lot!! Matthias

Interesting Open Source Project: Cocoa Dialog
by Daniel Lord Feb. 15, 2006

Feb. 15, 2006

(Unless of course its been mentioned here before and then in the words of SNL's immortal Emily Latella: "Never mind!") CocoaDialog seems to fill that gap between the command-line and PyObjC providing a 'quick and dirty' GUI interface for scripts (Python. Perl. Shell, Ruby, etc.) I just found it while 'googling up' up some AppKit NSTextContainer subtleties I was having trouble figuring out and I thought I'd pass it along. How Google put those two together I'll never know ;-) Clearly it doesn't replace PyObjC's power and breadth, but it might have a place in the toolbox for smaller projects. Kind of a Growl/ Display Dialog artifice. http://cocoadialog.sourceforge.net/documentation.html Daniel

problems with 2.4.1 installer
by Bill Janssen Feb. 14, 2006

Feb. 14, 2006

I just downloaded and ran the two recommended 10.4 Python installers. I noticed two things: 1. The readme for the 2.4.1 installer says it's for Mac OS X 10.3. It should say 10.3 and 10.4. 2. The IDLE app is bit hard to find, being in /Applications/MacPython-2.4/, along with a bunch of other (dead or dying?) apps, like PythonIDE and PackageManager. These problems should be addressed in the 2.4.2 release. Bill
