multiple pythons on one machine
by Ted Leung Nov. 14, 2004

Nov. 14, 2004

Okay, I'm getting to the point where I think I'm going to end up with multiple Python's on my system (not including the chandler one): 1. Apple's 2. the one from fink -- i've been trying not to install this one because I wasn't sure about bad interactions 3. 2.4b2 Right now I only have #1 installed. Are there any issues I need to be aware of before I try and install 2 and 3 (I expect to have to build this one). I'm also under the impression that 2.4b2 will build as a framework by default, so does that mean I should apply Bob's patch: <http://mail.python.org/pipermail/pythonmac-sig/2004-September/ 011695.html> in order to not mess up the Apple Python? I assume that I can install distutils based packages into the various pythons by using the correct python to run setup.py I know that this is a FAQ, and I looked through some old messages and the FAQ, but I still feel a bit uncomfortable. (I'd be happy to try to improve the FAQ on the wiki). ---- Ted Leung Blog: <http://www.sauria.com/blog> PGP Fingerprint: 1003 7870 251F FA71 A59A CEE3 BEBA 2B87 F5FC 4B42

IDLE
by François Granger Nov. 13, 2004

Nov. 13, 2004

I am on MacOSX 10.3.6 I installed TclTkAqua 8.4.7 from SourceForge http://sourceforge.net/project/showfiles.php?group_id=86100&release_id=21946 0 I launched IDLE and played with the font preferences and menu commands with just a small script opened. It crashed after five minutes. Is IDLE usable on Mac ? If the answer is yes, which versions of the various components are recommended ? -- François Granger fgranger(a)fgranger.com + 33 6 61 36 96 17 (mobile) + 33 1 47 35 00 16 (home)

by Bob Ippolito Nov. 13, 2004

Nov. 13, 2004

I've patched Numeric 23.6's setup.py to link against Apple's BLAS implementation. It shouldn't cause any problems for other platforms: http://undefined.org/python/mpkg/patch/Numeric-23.6/setup.py A Numeric 23.6 installer for Mac OS X 10.3 and later (using the stock Python 2.3 interpreter), built with py2app 0.1.5's bdist_mpkg command: http://undefined.org/python/mpkg/python2.3/Numeric-23.6.mpkg.zip -bob

Looking for OpenOffice driven by python 2.3
by Dr. Ludger Humbert Nov. 12, 2004

Nov. 12, 2004

Hi, is there anyone out there, who had success in replacing the delivered python, which comes with OpenOffice? If you don't know what I'm taking about, you may look at: http://udk.openoffice.org/python/python-bridge.html#replacing Why do we need it? We are running ponto to enable pupils (6 grades) to work with python and to realize, that there are concepts (which may turn in "mental models" - we hope) http://ddi.cs.uni-dortmund.de/projekte/ponto [it will be published in the next few days - at the moment you'll find a description of the project] But there is a main drwaback: pupils should be enabled to use rlcompleter when they are working with python to create their documents. So we need python, which supports py uno bridge on one side, but readline too. Pls help us the pupils need our support Ludger Humbert

parsing system_profiler xml output
by brad.allen＠omsdal.com Nov. 12, 2004

Nov. 12, 2004

I ran across a recent recipe from Brian Quinlan for parsing the XML output of the system_profiler command (the XML output feature was introduced in 10.3). Here is the URL, and I've pasted the source code at the bottom of this email. http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/303063 "system_profiler returns it's XML data info pinfo format so this recipe contains a partial pinfo parser. This recipe also requires PyXML to do the key-based querying..." I'm confused about this. The descriptive text says that PyXML is required, but the import statements don't refer to PyXML. Also, I think "pinfo format" is probably really plist, since that's the DTD referred to in the system_profiler output. Maybe there's a way to do this using plistlib instead. I would post my comments at the Python Cookbook site, but I'd rather clear up my cluelessness first. Any thoughts on this would be appreciated. Anyway, when I try to run the recipe, it fails with the following traceback: oms-ballen:/OMS/IT_Tools/scripts/misc python ballen$ python system_profiler_xml.py Traceback (most recent call last): File "system_profiler_xml.py", line 137, in ? main() File "system_profiler_xml.py", line 134, in main print '%s: %s' % (k, info[k][0]) File "system_profiler_xml.py", line 91, in __getitem__ from xml import xpath ImportError: cannot import name xpath -------------------------------------------------------------------- source code for this recipe ----------------------------- #!/usr/bin/env python from xml import dom from xml.dom.xmlbuilder import DOMInputSource, DOMBuilder import datetime import time import os def group(lst, n): """group([0,3,4,10,2,3], 2) => [(0,3), (4,10), (2,3)] Group a list into consecutive n-tuples.

Question re: py2app
by Kevin Walzer Nov. 11, 2004

Nov. 11, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've found a bug in wxGlade that only seems to exist in the version I packaged with py2app, as a standalone. Whenever I try to generate code using this program, I get an error message that says "no parser found"--apparently it can't find the parsers to convert the XML GUI description to Python code. It looks like at least one file, xml_parse.pyc, didn't get copied into the bundle by py2app, which may explain the problem. This doesn't exist when I run the program from a folder (double-click wxglade.py), nor does it exist when I bundle it as an applet (wxglade + all related files into an app bundle, but external libraries/modules like wxPython left alone)--but all I do with the applet bundle is copy all the wxglade files manually into the bundle into the Resources folder, keeping the same directory structure otherwise. I'm just not sure why that particular file isn't being copied when I run py2app. - -- Kevin Walzer, PhD WordTech Software--Open Source Applications and Packages for OS X http://www.wordtech-software.com http://www.smallbizmac.com http://www.kevin-walzer.com mailto:sw@wordtech-software.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBk3JjJmdQs+6YVcoRAtROAJ9rlidPAzqwadtcdpxXH6sowJ9S/gCfaYxN CzuL9+DO9nUh4zopyeHNwBA= =gsxO -----END PGP SIGNATURE-----

Update on PyQt-Mac forthcoming

Nov. 10, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 A major bug with my build of PyQt-Mac has been brought to my attention--I built Qt with static libraries, but PyQt looks for shared libraries. This will necessitate a rebuild of everything, which will take some time.

ANN: wxGladeOSX version 0.3.5.1
by Kevin Walzer Nov. 10, 2004

Nov. 10, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The latest version of wxGlade, v. 0.3.5.1, is now available in a native Mac OS X application bundle. This release is a complete standalone version and no longer requires a separate installation of wxPython thanks to Bob Ippolito's py2app tool. As such, it may be of interest not only to wxPython developers, but also to any Mac-based wxWidgets developer; it can generate C++, Python, Perl, and XRC code. wxGlade is free and open-source. The Mac OS X build is available from http://www.wordtech-software.com/wxglade.html.
