Where am I ?
by Jerry LeVan Sept. 13, 2004

Sept. 13, 2004

Hi, I am fairly new to python, there is a task I need to figure out. Suppose I have my "main" program in a folder, and various support modules in *folders* in the same folder as the main program. How can I import stuff from the folders? Can I do this so that if everything gets moved to a new location, the imports will still work? In tcl I can do something like: set basedir [file dirname [info script]] <-- get the dir containing main source [file join $basedir Support pgconnect.tcl] <-- load others... source [file join $basedir Support Help.tcl] <-- contained in source [file join $basedir Support readme.tcl] <-- basedir/support source [file join $basedir Support tableInfo.tcl] Thanks, Jerry

quicktime info?
by Arthur Elsenaar Sept. 13, 2004

Sept. 13, 2004

Hi, looked around the archives and documentation, but can't find information on how to use some very limited quicktime functionality. The main functionality I need are the movieplayer to load a sound file, duration and position information. I like to add this an existing pythoncard application, so I suspect a PyObjC solution is out the door? Thanks, Arthur.

IDE with vi keybindings
by Ksenia Marasanova Sept. 13, 2004

Sept. 13, 2004

Hi, I currently use Vim for Python coding and I am quite happy with it. However, from time to time I google for a 'real' IDE, but there's seems to be not much results... So this time I want to ask: Can anybody recommend a (Python) editor / IDE, which runs on OSX and has vi key bindings? Except for Vim :) Thanks! Ksenia.

Python Postgresql support?
by Jerry LeVan Sept. 13, 2004

Sept. 13, 2004

Is it possible to build the python postgresql support library on Mac OSX 10.3.5 with the default python install? Adding "--with-python" gets an error message about libpython not being a shared library when attempting to build postgresql. (pg 7.4.5) Thanks for any pointers. Jerry

MacPython Syntax Highlighting?
by rtjohan＠syspres.com Sept. 11, 2004

Sept. 11, 2004

Hello, Just starting to use MacPython, but was surprised to see the default setup doesn't seems to have syntax highlighting. Is there a way to enable that? When used IDLE when suffering on Windows, I believe IDLE did have this feature. Thanks, Richard

PythonIDE w/ DarwinPorts Python?
by rtjohan＠syspres.com Sept. 11, 2004

Sept. 11, 2004

Been using darwin ports to install postgresql, python, apache2, psycopg with great success on MacOSX 10.3.5. So, I use the darwin ports python which is installed in /opt/local/bin/python. Wondering how to tell PythonIDE to use this darwin python instead of the built-in python. The darwin python contains all the python packages. One way I can think of is to use softlink to redirect to darwin python. Hate to be messing with the default install though, would imagine there is some configuration file that can be modified instead. Any tips most welcome. Thanks, Richard

Error in loading Bundle on Mac OS X 10.3.4
by Brian Christensen Sept. 11, 2004

Sept. 11, 2004

I posted this problem to the wxPython-mac list, but no one there was able to solve the problem. Maybe you folks can help. -------- My wxPython application works perfectly on my Mac OS X 10.3.4 test machine, but it does not load for one of my users. He also has Mac OS X 10.3.4 installed. He has tried in on both his laptop and desktop machines with the same result. I appreciate your help in trying to track down this problem. I have some additional data that may help to track down this problem. I have the output of the "set" command on both the users machine and my test machine. I also have the results of the "otools -L" command from my development machine. It has been a couple of weeks since my last post on this so I will repeat the error message he is getting: ===== Wed Jul 14 2004 ===== 17:47:12 US/Pacific ===== Traceback (most recent call last): File "/Users/andycarter/Desktop/GanttPV v0.1.1 Folder/GanttPV.app/Contents/Resources/GanttPV.py", line 45, in ? import wx File "/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site- packages/wx/__init__.py", line 19, in ?

Or any suggestions what I > could check next? Unfortunately I have no ideas. The wxPython extension modules will have encoded in them the paths to the wxMac dylibs they use, but setting DYLD_LIBRARY_PATH will cause the dynamic loader to look in that location first. What appears to be happening is that the DYLD_LIBRARY_PATH being put in os.environ in the bundle's startup script is being ignored for some reason and so the loader is still looking in the compiled in path, which doesn't exist. I fooled around with this for a while this morning by building a standalone bundle for the superdoodle sample. I then moved my installed wxMac libs to another location so they wouldn't be found by the bundle. The bundle loaded and ran fine. I then tweaked the startup script so that it wasn't setting DYLD_LIBRARY_PATH and then I got an error just like what you reported. The only other thing I can think of to try is to build your bundle on a Panther system and see if it makes any difference. (You could even do semi-standalone in that case to not include the Python framework since it will already be on the target machines.) -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython! ------ end of wxPython-mac list response ------ The following is the information I included in my post to the wxPython-mac list: This is the contents of the python file in the bundle that that tells the Mac where to find the library files. ----------- start of file ------------------------------ #!/usr/bin/python import sys, os execdir = os.path.dirname(sys.argv[0]) executable = os.path.join(execdir, "Python") resdir = os.path.join(os.path.dirname(execdir), "Resources") libdir = os.path.join(os.path.dirname(execdir), "Frameworks") mainprogram = os.path.join(resdir, "GanttPV.py") sys.argv.insert(1, mainprogram) if 1 or 0: os.environ["PYTHONPATH"] = resdir if 1: os.environ["PYTHONHOME"] = resdir else: pypath = os.getenv("PYTHONPATH", "") if pypath: pypath = ":" + pypath os.environ["PYTHONPATH"] = resdir + pypath os.environ["PYTHONEXECUTABLE"] = executable os.environ["DYLD_LIBRARY_PATH"] = libdir os.environ["DYLD_FRAMEWORK_PATH"] = libdir os.execve(executable, sys.argv, os.environ) ----------- end of file ------------------------------ Per my request, the user opened the Mac bundle and confirmed that the "missing" file is there.

appscript 0.6.0 tentatively posted
by has Sept. 9, 2004

Sept. 9, 2004

Hi all, New, preview-ish version of appscript (0.6.0) now posted at: <http://freespace.virgin.net/hamish.sanderson/appscript.html> Feel free to kick the wheels. :) This is a ground-up rewrite, implementing appscript as a wrapper round the lower-level aem package. It lacks the automatic reference validation of previous versions (this could be provided as an optional extension) so won't catch user errors like badly-formed references. OTOH, it's much more forgiving of buggy application terminology resources (a common problem). References also lack built-in help() methods at this point, though could add them in again later if folk think they'd be useful. Sorting out documentation is next, after which I'll start on Apple Event Object Model support for aem.receive. Comments, suggestions, brickbats, etc. to the usual address, ta. has p.s. One minor change in the aem and appscript APIs: the NOT() method used in constructing test references has been replaced with a NOT property. Otherwise, they should be identical to before. -- http://freespace.virgin.net/hamish.sanderson/

Measuring the users idle time
by Gabriel Birke Sept. 9, 2004

Sept. 9, 2004

Hello! Is there any way to measure the the time the user was idle? Maybe with the Carbon call InstallEventLoopIdleTimer? I don't care if I get the number of seconds the user was idle or if I have to write the callback myself. Thanks Gabriel
