Appscript
by Conan C. Albrecht Dec. 12, 2008

Dec. 12, 2008

I'm using appscript to script Word and BibDesk. I need to run the script from the "Scripts" menu in one of these programs. However, my .py script won't show up on their menus, even if the script is in the right directory. The python script will show up on the system- wide scripts menu, but not on an application's menu. I changed the file extension to .scpt, and it still won't show up. To fix this, I added a simple AppleScript to the same (scripts) directory. I've included this at the bottom, if it helps. So the AppleScript runs first, then it calls "do shell script" to run the Python program. My problem is that the script can't call any GUI functions, such as the following: import osax sa = osax.OSAX() # allows use of standard additions (like display dialog) sa.display_dialog("Hi world") If I run from the command line, the dialog shows up fine. If I run from within Word or BibDesk, the dialog doesn't show up at all. I think it is because "do shell script" runs it in an invisible shell that can't access the main GUI. So the dialog comes up, but is not visible to the user. The calling application (Word or BibDesk) freezes since the dialog is "up" but can't be responded to by the user. Is there a better way to do this? How can I run Python scripts from the Scripts menu in a program? Thanks in advance. ================================= -- Get this script's directory and name tell application "Finder" to (path to me) as Unicode text set scriptname to POSIX path of result -- Remove the .scpt extension, and append .py instead set AppleScript's text item delimiters to {".scpt"} set textItems to text items of scriptname set AppleScript's text item delimiters to {""} set scriptname to textItems as string set scriptname to scriptname & ".py" -- Run the script do shell script "python '" & scriptname & "'" =================================== ____________________________________ Conan C.

using appscript to add a login item?
by Bill Janssen Dec. 4, 2008

Dec. 4, 2008

I'm trying to add a login item in an installer, and I thought using appscript would be the simplest way. >>> from appscript import * >>> a = app("System Events") >>> a.login_items() Sure enough, a display of items. But how do I create a new one and add it? Bill

py2app and PyQt4
by Jeremy Sanders Dec. 2, 2008

Dec. 2, 2008

Hi - I'm having problems with my PyQt4 application which uses pyuic dynamically to load in dialogs. Firstly py2app doesn't seem to include sip in the output dist, but does include PyQt4. Presumably it should work out that PyQt4 is dependent on sip. I can fix this with an explicit import sip, but maybe it should automatically include sip for PyQt4. The second problem is that it isn't properly handling this code in PyQt4: try: from xml.etree.cElementTree import parse, SubElement except ImportError: try: from cElementTree import parse, SubElement except ImportError: try: from elementtree.ElementTree import parse, SubElement except ImportError: from PyQt4.elementtree.ElementTree import parse, SubElement It fails when running the app on the final import, even though it should successfully be doing the first xml.etree.cElementTree import from the first line. I tried an explicit xml.etree.cElementTree import elsewhere in the code but this doesn't fix the problem. The other issue is in my code. To allow users to run the app without installing it, I have this code in the main script: # Allow veusz to be run even if not installed into PYTHONPATH try: import veusz except ImportError: # load in the veusz module, but change its path to # the veusz directory, and insert it into sys.modules import __init__ as veusz thisdir = os.path.dirname( os.path.abspath(__file__) ) veusz.__path__ = [thisdir] veusz.__name__ = 'veusz' sys.modules['veusz'] = veusz It doesn't process the program properly with this code. If I replace this block with just "import veusz" it works. This doesn't make much sense to me. I have another problem with an extension module, but I will save that for another email.

More like UInt32. IIRC type/creator > are stored in big-endian order. Ok, but how can I convert those Ints to string? I get them as Ints also from UTGetOSTypeFromString: >>> from LaunchServices import UTGetOSTypeFromString >>> UTGetOSTypeFromString('public.jpeg') 1886741100 >> Anyway, the traditional MacOS type and creator would be a nice >> addition.

That works, but I'd prefer a "future proof" method. Greetlings from Lake Constance! Hraban --- http://www.fiee.net https://www.cacert.org (I'm an assurer)

In any case, it looks like you've got a static lib for the Chris> main python lib, and py2app with require a dynamic one. Hmmm... I just built a framework version. I configured like so: ../configure --enable-framework='/Users/skip/Applications' \ --enable-shared --prefix='/Users/skip/local' \ CPPFLAGS='-I/Users/skip/local/include -I/opt/local/include' \ LDFLAGS='-L/Users/skip/local/lib -L/opt/local/lib' No .dylib file was created. I ran make altinstall then checked in both /Users/skip/Applications/Python.framework and in ~/local. Still no Python .dylib files. Then I scoured the Makefile looking for promising targets to try. I tried making both sharedmods and sharedinstall. Nothing. Thinking the --enable-framework and --prefix flags might mess up configure in some way I reconfigured without specifying --prefix. make clean. make sharedinstall. Still no dylib files. Any other ideas I might try? I finally just submitted a bug report: http://bugs.python.org/issue4472 Thanks, Skip

Building Python 2.3 on Mac OS X 10.5.5
by skip＠pobox.com Dec. 1, 2008

Dec. 1, 2008

I'm trying to build Python 2.3 on my Mac (OS X 10.5.5) so I can use it simply to test my lockfile package. It configures fine and the basic make step works, but the executable has some sort of problem with semaphore operations: % ./python.exe sem_init: Function not implemented sem_wait: Bad file descriptor sem_post: Bad file descriptor sem_wait: Bad file descriptor sem_post: Bad file descriptor sem_init: Function not implemented sem_trywait: Bad file descriptor sem_wait: Bad file descriptor sem_post: Bad file descriptor sem_init: Function not implemented ... lots of similar messages ad nauseum ... sem_post: Bad file descriptor sem_init: Function not implemented sem_trywait: Bad file descriptor sem_wait: Bad file descriptor sem_init: Function not implemented sem_post: Bad file descriptor Traceback (most recent call last): File "/Users/skip/.python.py", line 21, in ? from save_session import mark, save, load File "/Users/skip/misc/python/save_session.py", line 21, in ? raise ImportError("session save/restore requires readline module") ImportError: session save/restore requires readline module >>> I compared the code related to sem_init between 2.3 and trunk but didn't see anything which looked promising. Any thoughts? Thx, -- Skip Montanaro - skip(a)pobox.com - http://smontanaro.dyndns.org/
