If someone could run the following program on a Darwin machine, not MacOSX, and email me the results, I would appreciate it. Since I run several computers at my home, I now have the output for MacOSX, Cygwin, Win32 and Linux. If anyone can email me the output for other OSes such as Solaris, Sun, etc, I would appreciate that too. Thanks for your help.

IDE crash
by Michael Davidson Nov. 30, 2004

Nov. 30, 2004

I have installed the Nov 7,2003 add ins from http://homepages.cwi.nl/~jack/macpython/. My IDE used to work. I foolishly was playing with menu options that I should not have played with, and now my IDE crashes immediately after starting. The menu option I changed was the location of my scripts directory. I set it to a directory with no python scripts, and the IDE crashed. It wouldn't restart. I deleted my prefs file; I reinstalled the IDE. No luck. This is the traceback from the console. If anyone can send me a prefs file that will fix my IDE, I would be much obliged. Traceback (most recent call last): File "/Applications/MacPython-2.3/PythonIDE.app/Contents/Resources/PythonIDE.py", line 59, in ? _PythonIDEMain.PythonIDE() File "/Applications/MacPython-2.3/PythonIDE.app/Contents/Resources/PythonIDEMain.py", line 41, in __init__ Wapplication.Application.__init__(self, 'Pide') File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 28, in __init__ FrameWork.Application.__init__(self) File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/FrameWork.py", line 115, in __init__ self.makemenubar() File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 275, in makemenubar self.makeusermenus() File "/Applications/MacPython-2.3/PythonIDE.app/Contents/Resources/PythonIDEMain.py", line 159, in makeusermenus self.makescriptsmenu() File "/Applications/MacPython-2.3/PythonIDE.app/Contents/Resources/PythonIDEMain.py", line 261, in makescriptsmenu self.scriptswalk(fsr.as_pathname(), self.scriptsmenu) File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 309, in scriptswalk self.scriptswalk(path, submenu, done) File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 309, in scriptswalk self.scriptswalk(path, submenu, done) File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 309, in scriptswalk self.scriptswalk(path, submenu, done) File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 308, in scriptswalk submenu = FrameWork.SubMenu(menu, name) File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/FrameWork.py", line 708, in SubMenu return menu.addsubmenu(label, title) File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/FrameWork.py", line 595, in addsubmenu sub = Menu(self.bar, title, -1) File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/FrameWork.py", line 545, in __init__ self.id, self.menu = self.bar.addmenu(title, after, id) File "/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/plat-mac/FrameWork.py", line 479, in addmenu id = self.getnextid() File "/System/Library/Frameworks/Python.framework/Versions/2.3/Mac/Tools/IDE/Wapplication.py", line 433, in getnextid id = self.possibleIDs[0] IndexError: list index out of range thanks, Michael

Using embedded python programs from DarwinPorts.
by Robert White Nov. 29, 2004

Nov. 29, 2004

Excuse me for bringing up the following if it has previously been discussed and I missed it. Recently, I started using DarwinPorts again to install some programs that I like to have around. However, I noticed that several programs that embed Python force an installation of python 2.3.4 into DarwinPorts for MacOSX 10.3.6 rather than just using the built-in python. So, in the case of Glom, XChat2 and cvs2svn, I started researching how to change the appropriate autoconf et al files to properly link to or set up in the builtin Python. (Probably, mostly m4 macros) In doing that I contacted two different Port Maintainers asking some very basic questions. One stated that "port" is smart enough to use the builtin-Python Framework and not pull in the unix version which is not my experience. The other stated that "The darwinports policy for both perl and python modules is to only use the darwinports-provided versions of these languages. The reason is that doing something else would require installing files outside of the darwinports prefix (which is /opt/local by default).". While I find those comments to be justified, I am wondering if it would not be possible to use the builtin version if one were to have their own PYTHONPATH environment variable defined and otherwise pull in a different version. (I am probably wrong, but I think that a PYTHONPATH variable addresses most of the problem especially if it is pointing back into /opt/local somewhere.) I know that this ultimately must be presented to the DarwinPorts Group, but I know that several on this list are very active there and may indicate to me that this is not a worthwhile investment of my time. So, I wanted to get your opinions first of whether I should pursue this or not and if so, any gotchas that you might be aware of.

I had tried appscript but hadn't figured it out either. Specify? >The above works fine except it doesn't pick up events from other >days that repeat on the current date. Tsk. I rarely use iCal, so wasn't aware of this. But I've checked and, yes, start and end date refer to the original event as defined by the user. iCal's designers obviously didn't think through the implications when the event is also set to repeat. (Like I say, iApps' scripting implementations are notoriously second-rate, hardly the showcase you'd expect.) Only solution I can see is to get the start dates of all events and do the math yourself. It's slower and less convenient but at least it works: #!/usr/local/bin/pythonw from appscript import * from datetime import date, timedelta today = date.today() ref = app('ical.app').calendars[1].events print [r for r, d in zip(ref.get(), ref.start_date.get()) if not (d.date() - today).days % 7] >Is there documentation that I could look at that shows me what calls >I can make on the various objects? No, aete [Apple event terminology] resources don't carry this info (sdefs, their eventual replacement, will have limited information on which commands work on each class), and most applications have little or no additional documentation on their scripting interfaces. Yes, this sucks. >I'm guessing there's a way to change the filter to pick up repeating >events, but I don't know where to look. No, application object references - actually simple relational queries - always follow a standard structure. Notes: An Apple event interface isn't like COM where you just chuck a bunch of raw function calls out in the wild; it's a complete View-Controller layer with its own interaction rules: the Apple Event Object Model defines a standard system for referring to objects and the application developer defines the commands and classes they wish to present (which may or may not bear any resemblance to the internal data structures in the application's Model layer). It's a good system in itself, but the quality and quantity of support for it in both first- and third-party applications varies wildly. On a good day, you can do everything you want with a few references and commands; on a bad day you have to grab raw data and process it yourself; on a really bad day you're reduced to using GUI Scripting to manipulate the app (ugh!); and at worst it's impossible. Some application developers do a good-to-excellent job of implementing - and even documenting(!) - Apple event interfaces (e.g. Finder, InDesign, Entourage), but there's a lot of companies/developers out there who don't bother, or just don't seem to 'get it', or just bodge an quick-n-ugly AE wrapper around whatever existing APIs they already have (e.g. Word & Excel 2004). C'est la vie. Third-party language bridges like appscript can save you the pain of having to deal with the ugly, underpowered can-o-worms that is the AppleScript language, but they can't do anything to address the deficiencies of individual applications. Feel free to submit feature requests/bug reports/etc. to Apple and application developers: the more they hear from folk, the more likely they are to pay attention.

PyObjC py2app-branch merged to trunk
by Bob Ippolito Nov. 29, 2004

Nov. 29, 2004

The py2app-branch of PyObjC has been merged to trunk, and development will continue on trunk. For those of you that have checked out py2app-branch, please svn switch back to http://svn.red-bean.com/pyobjc/trunk/pyobjc Enhancements include but are not limited to: - All buildapp.py scripts are gone, bundlebuilder is no longer used anywhere. Examples now have setup.py scripts and are built with "python setup.py py2app". - The way setup.py works has changed significantly. It now supports a bdist_mpkg command to build a .mpkg distribution containing both PyObjC and py2app - Includes a copy of what will be py2app 0.1.6 (or possibly 0.2.0 .. depending on what else I change) - Enhanced compatibility with the Apple Objective C runtime - Bugfixes and minor feature additions on several other fronts - A sandbox directory with some new half-baked ideas for a new Objective C header parser The Xcode template still does not support py2app. I would recommend that if you use Xcode, you should only use it for development. Deployment should be done using py2app. -bob

scripting iCal
by David Reed Nov. 29, 2004

Nov. 29, 2004

I've ran across this: http://stompstompstomp.com/weblog/technical/2004-02-05 and got the examples in it to work fine. I'm now trying to write a script to just grab the events for the current date. I could pull all the events and check their start date, but figure there is probably an easier way. The applescript documentation includes: Class calendar: This class represents a calendar Plural form: calendars Elements: event by numeric index, before/after another element, as a range of elements, satisfying a test todo by numeric index, before/after another element, as a range of elements, satisfying a test but it's not clear to me how to grave events that "satisfy a test". Can anyone help or point me to documentation on this? Thanks, Dave

Use appscript: http://freespace.virgin.net/hamish.sanderson/appscript.html Example: #!/usr/local/bin/pythonw from appscript import * from datetime import date, timedelta today = date.today() tomorrow = today + timedelta(1) # To get a list of today's events in calendar 1: print app('ical.app').calendars[1].events.filter((its.start_date >= today).AND(its.start_date < tomorrow)).get() # To get names and descriptions of today's events in 'Home' calendar: ref = app('ical.app').calendars.filter(its.title == 'Home').events.filter((its.start_date >= today).AND(its.start_date < tomorrow)) print zip(ref.summary.get(), ref.description.get()) Notes: - iCal's scripting support isn't too great - like most of Apple's iApps. Hence stupid crap like using filters to get calendars by title: the doofuses that defined its Apple event object model used 'title' instead of 'name' for no obvious reason, which prevents you from just using calendars['Home'] as you would in most apps. - For asking advice on scripting specific applications, you might want to subscribe to the macscrpt mailing list: <http://listserv.dartmouth.edu/scripts/wa.exe?A0=macscrpt&D=1&H=0&O=D&T=1> HTH has -- http://freespace.virgin.net/hamish.sanderson/

Python 2.3.4 Installation
by Samuel M.Smith Nov. 28, 2004

Nov. 28, 2004

There isn't much on the new 2.3.4 Mac Python. Does 2.3.4 fix the problem where you couldn't have any framework version but the one that came with OSX (in this case 2.3 for Panther) ?. Does the install from source replace 2.3? There were a lot of posts about problems building extensions and stuff with a different version etc. Have those issues been resolved? More of a what is the current state of Python 2.3.4 framework on os x 10.3.5?

embedding -- linking problem?
by John Fowler Nov. 28, 2004

Nov. 28, 2004

Consider me a newbie at both python and MacOS. All discussion below pertains to python-2.3.4 using gcc and g++ compilers on MacOSX10.3. I configured python with ./configure --prefix=$PWD --exec-prefix=$PWD. Then I added a module in Modules/Setup and put the .c file in Modules. I built python and can import my module just fine. Next I wrote an app that calls Py_Initialize(), then PyRun_SimpleString("import mymodule\n"). To see what to add to my link line, I ran the python that I just built with: import distutils.sysconfig distutils.sysconfig.get_config_var('LINKFORSHARED') What I got from this was: '-u __dummy -u _PyMac_Error -framework System -framework CoreServices -framework Foundation' So I put this in my Makefile and linked statically to the libpython2.3.a that I just built. It compiles fine with g++ but runs correctly ONLY if I have PATH set so that the directory for Python-2.3.4 comes first. Otherwise the app can't find mymodule. So the app isn't portable. What am I missing? (This same approach works correctly on linux except what I had to add to link there was '-Xlinker -export-dynamic'.) Thanks, John Fowler

Embedding Python in applications under MacOSX and Darwin.
by Robert White Nov. 28, 2004

Nov. 28, 2004

I am wondering if someone can answer this question for me. Is Python installed as a framework under Darwin? If so, is there an easy way to know within a "configure" script (autoconf, libtool, et al) whether you are in MacOSX or Darwin? I do not run Darwin, just MacOSX. The reason that I ask this is that there are several programs that embed python within the Darwinports system and I would like to develop a common routine that would allow a "configure" script to properly compile and link against the Python Framework in MacOSX yet work in Darwin as well. I have not looked at a lot of ports, but the ones that I have looked at don't get it right and I am too new to the libtool system to provide a proper response. So any information or pointers are greatly appreciated. Thanks, Bob.
