One more thing. While the above is a bare minimum from the command

Re: [Pythonmac-SIG] Python control/integration of a Cocoa/Quicktime application?
If you write an Objective-C framework, the python code to wrap it
using PyObjC is very short. Here is an example I use to expose Tim
Omernick's CocoaSequenceGrabber framework to capture images from the
iSight camera:
example
import objc, AppKit, Foundation, os
if 'site-packages.zip' in __file__:
base_path = os.path.join(os.path.dirname(os.getcwd()), 'Frameworks')
else:
base_path = '/Library/Frameworks'
bundle_path = os.path.abspath(os.path.join(base_path, 'CocoaSequenceGrabber.fram
ework'))
objc.loadBundle('CocoaSequenceGrabber', globals(), bundle_path=bundle_path)
del objc, AppKit, Foundation, os, base_path, bundle_path
/example
I have that saved as PySight/__init__.py so I can import * from
PySight to get all the objects and methods from the framework. It
would be shorter, but I have some path manipulation so that it works
from the command line and from within an application bundle built with
py2app. The bare minimum you need is:
import objc
objc.loadBundle('MyBundle', globals(),
bundle_path='/my/bundle/path/MyBundle.framework')
Writing a bundle in Python that can be imported by an Objective-C
application is similarly easy. I have some blog posts on that topic
if you ever decide to try that direction. The application just needs
to take Objective-C bundles as plugins, it does not have to plan for,
or even know about, Python in the bundle implementation.

The AppKiDo application makes it very easy to browse and search the documentation. 1) I noticed that my code runs fine directly from the shell prompt, so I'm curious what the advantage of making a real .app is. I guess this would allow me to add the program as a Startup Item. (Or can one run any command as a Startup Item?) Making it a real application makes it double-clickable from the Finder and may make it behave better with other Cocoa applications. You will see your application's name when you switch to it, rather than Python. And I think Startup Items are expected to be .app applications, although I wouldn't swear to it. It's relatively easy to make it a .app with py2app, and good practice for when you develop a killer app that you want to distribute far and wide. 2) It is easy to change the colour of the title text that appears in the menu bar?

There are tutorials on the PyObjC website. It is what I generally use for GUI applications. You can then build them using py2app to get a standard Mac application and there is no visible sign that your application is written in Python. I hope that helps.

Re: [Pythonmac-SIG] Multiple python 2.5 framworks
If you build an actual OS X application using py2app, it will embed the Python2.5 framework into the app with no conflict. I have many full python2.5 frameworks installed, from various applications I have built this way, as well as MacPorts and fink (non-framework) versions. I make sure my path points to my standard framework install and that is not picked up by any application I've built with other frameworks, including those which may include special-built frameworks, or older versions of Python. If you are not using py2app to build your applications, then your mileage may vary, but you can still easily have multiple framework installs. Just make sure that each application is referencing the right framework. How you do that depends on how the applications are run. But I strongly recommend that you use py2app for anything you distribute to users: They then have no path dependencies and don't have to build anything, just drag your application to their / Applications folder and they're done. --Dethe On 7-Feb-07, at 10:22 AM, Brian Granger wrote: Hi, We need to deploy a qt4 based python app and I am working on some of the build issues.

Re: [Pythonmac-SIG] Opening an app from another app under different OS X versions
As Kevin said, you may only need the full path to your app. It's
remotely possible you would need the full path to open as well (/usr/
bin/open). Full paths are finicky though, and you will need to know
where your application is installed, if the help application is in
the app bundle, for instance. Also, paths are different on
internationalized versions of OS X.
The right way is probably to use PyObjC and the NSWorkspace object:
from AppKit import NSWorkspace
NSWorkspace.sharedWorkspace.launchApplication_('MyApp')
For more on Workspace services, there is this article: file:///
Developer/ADC%20Reference%20Library/documentation/Cocoa/Conceptual/
Workspace/index.html
Also, when you're launching an app with open, you don't need the -a
flag, but without it you do need the path to the application.

Repeated attempts to consolidate the library now die with the read/write error immediately. I don't think it's a problem with either drive since I can read and write from both of them. It may be that RAID is too slow to keep up with whatever iTunes is trying to do. I was hoping I could do a manual copy and then update all the locations via appscript. This having the advantage of allowing me to preserve metadata. I guess it's time to forget about the metadata since I'm not going to do the one-at-a-time location update from within iTunes. Can you set the metadata from AppScript? I'm assuming you can, but haven't been following this thread that closely. You could try backing up your iTunes/iTunes Music Library.xml file and write a script to parse it and set the metadata on your files once you've moved them. It looks like a standard plist file, so you can use the python plist library to do the parsing. I'm sure the unique Track ID will be different, but you could key off artist + title + size and reset the other information (play counts, rating, etc.). I'm pretty sure iTunes reads this file on startup to set up its internal database, but I don't have time to test this theory right now.

That did it, it's working beautifully now. Setting up the right environment for plugins is also very hard, if not impossible to do completely correct: cpython just isn't designed for having several completely seperate interpreters in one application (and no, Py_NewInterpreter/Py_EndInterpreter don't count). Different plugin bundles with py2app will share part of the environment, such as having a shared sys.path. So does that mean that I shouldn't run two Python plugins in the same program, or that I need to be careful that they have the same dependencies, or that the first contains all the dependencies of subsequent plugins, or what?

The hard part is that I've become dependent on it, so when something doesn't work, everything I'm doing comes to a screeching halt. I can't tell you how much I appreciate your quick responses in those cases. If you have two python plugins for the same program they should at the very least use the same version of python, using different versions of python may or may not work. OK, I generally rebuild my plugins with the latest versions of everything anyway, but good to know. I'd have to study the plugin main code to be absolutely sure, but AFAIK if plugins A and B both depend on package C they should depend on the same version of C because at runtime they will both use the version that's included in whichever of the plugins was loaded first. That shouldn't be a problem. If you can arrange for one of the plugins to be loaded first it would be useful to have that plugin include the Python framework and large extensions (like PyObjC). That way other plugins can stay very small and you don't get confusion on what gets loaded. Have you seen SIMBL? It's an input manager that loads plugins, so you can load arbitrary code into an existing application (kind of a gross hack, I know, but terribly useful when code injection wasn't working on Intel). The neat thing about it is how it is configured to only load plugins for certain applications, and only for specified versions of those applications. Having a meta-plugin for Python that did something similar would be cool. I think there is something like that for Quicksilver, but it would be nice to generalize for other plugins.

OK, I now have those versions as well, via easy_install [module]==dev
on each one. I had tried building them all from svn the other day,
but failed, perhaps because of having the wrong version of setuptools.
Could you check the Info.plist and the structure of the screensaver?
Info.plist should have a key PyResourcePackages with an empty array
as its value
yes, have that
and an PyRuntimeLocations that points to an embedded python framework.
PyRuntimeLocaions contains the value: @executable_path/../Frameworks/
Python.framework/Versions/2.4/Python
The patch I just checked in ensures that PyResourcePackages is
empty, with an unpatched version the array will contain some
strings and that messes up sys.path.
There should be a lib/python2.4 in the Resources directory of the
screensaver, that should contain site-packages.zip, site.py and a
lib-dynload directory.
Yes. It also contains a config directory which contains Makefile,
Setup, Setup.config, Setup.local.
To make absolutely sure you have my patched version you could check
py2app/bundletemplate/plist_template.py, there is a definition of
PyResourcePackages in there, the value of which should be an empty
list. One way to check:
. import pprint
. import py2app.bundletemplate.plist_template
. pprint.pprint(py2app.bundletemplate.plist_template.infoPlistDict
('dummy'))

P.S. Are you sure you installed the latest version of py2app in the
right version of Python? If you installed python2.5 after
installing python2.4 easy_install might point to the 2.5 version of
easy_install (if you have that installed), if it is
easy_install-2.4 should pick up the correct version.
I'm sure. I've been checking the site-packages directory before and
after running easy_install, and I've gone through and removed
old .egg directories (and checked the easy_install.pth) so I can be
sure I'm getting the right versions. I've checked to make sure I
have the current version of the SillyBalls code too. SillyBalls
doesn't even use setuptools, so whatever is broken is broken across
both distutils and setuptools (I haven't dug underneath yet to see
how these work, so it's still magic under the covers to me).
So still no idea why it's working for you, but not for me. Anything
else you can think of? I followed the instructions in the py2app
docs for removing old versions of py2app. If everything is
encapsulated in the .egg, perhaps I can revert to the earlier version
that worked?

[Pythonmac-SIG] Building plugins with py2app
Hi folks, I'm switching to to a recent py2app and moving to use setuptools- based builds instead of distutils. I've had several problems, but since I've been coding here and there in spare moments (including on the bus in the mornings), I haven't done a very good job of documenting them, I'm afraid. I do have one persistent problem building both apps and plugins, which is that the settings I add to my plist don't appear in the resulting app/Contents/Info.plist. After much hair-pulling I think that is the source of many of the weird problems I've been seeing. For example, with the following setup: from setuptools import setup setup( plugin=['PastelsView.py'], setup_requires=['py2app'], options=dict( py2app=dict( extension='.saver', plist = dict( NSPrincipalClass='PastelsView', CFBundleShortVersionString = 'Pastels 0.3', CFBBundleDisplayName = 'Pastels', CFBundleIdentifier = 'org.livingcode.applications.pastels', ) ) ) ) I end up with an Info.plist that has the following: CFBundleIdentifier = org.pythonmac.unspecified.PastelsView CFBundleDisplayName = PastelsView CFBundleName = PastelsView NSPrincipalClass = PastelsView So it does end up with the right principal class, but other values are wrong, and the principal class appears to be set correctly more because that is the name of the script file than because I set it explicitly. In another program the app failed to pick up its icon from the plist specifier CFBundleIconFile, but successfully got the icon when I added iconfile in the py2app options. When I try to load the above screensaver I get the console messages: 'import site' failed; use -v for traceback Traceback (most recent call last): File /Users/delza/Library/Screen Savers/PastelsView.saver/ Contents/Resources/__boot__.py, line 7, in ? _disable_linecache() File /Users/delza/Library/Screen Savers/PastelsView.saver/ Contents/Resources/__boot__.py, line 2, in _disable_linecache import linecache ImportError: No module named linecache 2006-10-11 21:19:00.209 System Preferences[382] PastelsView has encountered a fatal error, and will now terminate. 2006-10-11 21:19:00.209 System Preferences[382] An uncaught exception was raised during execution of the main script: ImportError: No module named linecache This may mean that an unexpected error has occurred, or that you do not have all of the dependencies for this bundle. 2006-10-11 21:19:00.210 System Preferences[382] ScreenSaverModules: can't get principalClass for /Users/delza/Library/Screen Savers/ PastelsView.saver Details: Python 2.4.3 PyObjC pyobjc-1.4.1a0 installed with python setup.py bdist_mpkg --open py2app 0.3.4 Setuptools 0.7a1dev_r51485 OS X 10.4.7 (Intel) Code for the screensaver available from Google Code: http:// code.google.com/p/pastels/source Code works from the command-line (not built into a bundle) with my test harness.

When I change the Info.plist by hand to reflect the desired bundle name (Pastels) I still see it as PastelsView, and it still fails to load, so I'm obviously missing something important.

For particularly large values of simple, I guess. For those who don't already speak Cocoa, PyObjC is annoyingly cumbersome. Using it requires that you understand Cocoa enough to know how to read its documentation, understand its message model, understand the way it handles object allocation, and be able to use Interface Builder. The value of simple being: Exposing all of Cocoa, in a standard way so that existing documentation is usable, from Python. The translation makes using Cocoa from Python simple (as simple as it can be). I get the impression that for those who've used Cocoa and prefer Python, it's a breath of fresh air...but for those who've not been swimming in a vat of Cocoa, it's not quite so appetizing. I have not used Objective-C for anything but a couple of trivial tutorials, I dove straight in with Python. I understand there is a bit of a learning curve, and I've blogged about some of my own learning experiences with PyObjC, Renaissance, and my love/hate relationship with Interface Builder on my blog: http://livingcode.blogspot.com/ I've been quiet there for awhile while I write my own blogging software (in PyObjC) to allow me to interate faster and get more of my PyObjC tutorial stuff posted. A lot of the time, when I've felt that I had to do too much work in PyObjC, it's because I was not doing it the Cocoa Way. And I totally agree that it can be a pain to learn The Cocoa Way in order to build a small, simple program. On the other hand, as you graduate to more complex programs, learning to do it right can ease your development work by orders of magnitude, so the investment can pay off. And some of the more hairy parts of Cocoa aren't necessary when you're working in Python, because you can just use the Python standard library (or 3rd party libraries), so you get the best of both worlds. There are some efforts at making an even simpler interface, namely PyGUI and Renaissance, but I would recommend you work with PyObjC, build your UI with Interface Builder, and use AppKiDo to supplement Apple's documentation. Note this goal from the PyGUI documentation page: Document the API purely in Python terms, so that the programmer does not need to read the documentation for another GUI library, in terms of another language, and translate into Python. That can be a good goal, but on the other hand, there is a *lot* of documentation on Cocoa, far more than PyGUI will ever achieve, and the PyObjC bridge makes it trivial to translate that into Python. And I wouldn't expect PyGUI to expose everything from Cocoa (not it's purpose, it's a cross-platform wrapper), so if there's something beyond what PyGUI offers, don't be afraid to dip back to PyObjC. I do think that PyGUI is a much better approach to cross-platform GUI tools than, say, wxPython. The cross-platform abstractions should be kept as high-level as possible, i.e., in Python, not in a huge C++ library that then gets wrapped in Python. --Dethe - Kent ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

What I really want to do is use both sqlite version 2 and sqlite version 3 since I have existing sqlite version2 DBs and new CoreData apps that use sqlite version 3. From a version/nomenclature standpoint there is a huge mess eg: py-sqlite works with either sqlite 2 or sqlite 3 and py-sqlite2 works with sqlite version 3. I have been using py-sqlite with sqlite version 2 successfully. First problem I see is that there are two version of Python on my Tiger system: /usr/bin/python version 2.3.5 The above is Apple-supplied Python. Apple uses it for internal scripting stuff, you should pretend it isn't there. Ignore it, don't use it, but whatever you do, don't try to remove or replace it. /usr/local/bin/python version 2.4.1 This is the one you want. If your shell doesn't already point to this by default when you type python on the command line, it should. Try which python to see what your default is. Second problem: The (Apple) installed version of sqlite3 is 3.0.8.6 py-sqlite 2.1 requires sqlite 3.2.2 py-sqlite 2.0 requires sqlite 3.1 py-sqlite 1.1 requires sqlite 3.x So it seems that py-sqlite 1.1 is the one I need. To complicate matters, there is also APSW (Another Python SQLite Wrapper) which can be used with any version of SQLite. http://www.rogerbinns.com/apsw.html If I install it my installed py-sqlite that used the python sqlite version 2 gets overwritten, not nice. It also seems to get instaslled in the python 2.3 library, also not nice. Probably your PATH environment variable points to the Apple-installed python before the current python. You can change this, probably in the .bash-profile file in your home directory. Make sure /usr/local/bin comes before /usr/bin in the PATH. If I go to darwin ports it wants to upgrade my python to 2.4.2 first. Why do you need DarwinPorts? You have both Python and SQLite installed already. Just download the wrapper (pysqlite or apsw) and install it using python setup.py build; sudo python setup.py install after making sure the correct python is in your PATH. Does anyone have a solution? See above. All in all the whole Python database (lack of) mess is ridiculous! I know that Guido does not feel that databases have any place in python but I don't get it, why does the batteries included not include database support, databases like MySQL, PostgreSQL SQLite? Python's batteries do include BerkelyDB out of the box, as well as gdbm and/or dbm, including a built-in portable implementation of dbm for platforms that don't have it already. There are wrappers for PostgreSQL, MySQL, Oracle, SQLite, etc. There are object-relational mappings like SQLObject. The python world has a very rich and lively database environment.

But py2app will let you build a self-contained application which will run off of a memory stick. You might be able to use filesystem tricks to hide the OS X application on Windows and the Windows application on OS X, to give the illusion that there is only one application (some CD ROMs do this, I believe). Or, could I count on Python always being installed on any OS X - equipped PC, and thus not need to install a separate copy on my USB stick in order to be able to run my app? You cannot count on the version of Python that will be installed, or any external libraries you depend on.

Re: [Pythonmac-SIG] getting started with PyObjC
Using XCode isn't really the best way to create PyObjC apps. The recommended way is to use InterfaceBuilder to create your UI, implement it with PyObjC, and use py2app to build the application from there. Check out the tutorial on the PyObjC site, and the docs for py2app. PyObjC tutorial: http://pyobjc.sourceforge.net/doc/tutorial.php Py2app documentation: http://undefined.org/python/py2app.html It sounds like you already have the nib and code, so that should work for you. If you have the nib, but no code yet, there is a script which will generate a python files with stubs built from your nib to get you started. Using the nibclassbuilder script is demonstrated in the tutorial. I hope that helps to get you started.

When I tried to create an action for 'tableView:objectValueForTableColumn:row:', IB told me it was not a valid action name. I guess that would make sense anyways, since these aren't actions at all. You don't have to tell IB about actions unless you want to bind them. In this case, all you need to do is tell it you have this custom class, and an instance of your class is the dataSource for your table.

[Pythonmac-SIG] Correct way to send info to running program
I want to be able to periodically send data to a running program, from the command-line. I was looking at the various NSPort classes, but just discovered that NSSocketPort is not a raw socket, but only intended to talk to other NSPort instances. Surely I'm not the only one who wants to be able to do this. Is there a one right way? Any guidance here would be appreciated. --Dethe There are only two industries that call their customers users ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

NSDistributedNotificationCenter?
You didn't really specify what your requirements are...
I'm trying to set up a simplest thing that could possibly work for
getting events from another application which doesn't really play
well with others. I have hacked it enough that it logs the events I
want to the console, so I can, for example, put a tail -f console.log
| grep [events I'm interested in] | sendMessageToMyApp. I was
intending to make sendMessageToMyApp be based on datagrams using
something along the lines of:
import socket
host, port = 'localhost', 8081
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.sendto('some data from the command-line', (host, port))
But I was thinking that I could use NSPort to receive these messages,
which was totally off base. I can apparently use CFSocket, but
realized that I should do a reality check and see if there's a better
way than the somewhat convoluted and roundabout path I'd set up.
It looks like NSDistributedNotificationCenter might work. I'll try
it out.
Thanks!

Re: [Pythonmac-SIG] SetSystemUIMode in python?
While Pyrex is a pretty reasonable way to write extensions, PyObjC or ctypes is generally less painful when wrapping a small number of functions. This is very interesting.

[Pythonmac-SIG] Building Twisted
Hi folks, Has anyone installed twisted 2.0 on Tiger? I don't think I've ever had trouble building Twisted before, but now they've made it dependent on Zope Interfaces, which won't build for me. I'm running OS 10.4, Bob's Python 2.4, latest svn of PyObjC and py2app. Here's the traceback I'm getting when I try to build Zope Interfaces 3.0.1: $ python setup.py build running build running build_py running build_ext building 'zope.interface._zope_interface_coptimizations' extension gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused- madd -fno-common -dynamic -DNDEBUG -g -O3 -Wall -Wstrict-prototypes - IDependencies/zope.interface-ZopeInterface-3.0.1/zope.interface -I/ Library/Frameworks/Python.framework/Versions/2.4/include/python2.4 -c Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/ _zope_interface_coptimizations.c -o build/temp.darwin-8.1.0- Power_Macintosh-2.4/Dependencies/zope.interface-ZopeInterface-3.0.1/ zope.interface/_zope_interface_coptimizations.o Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/ _zope_interface_coptimizations.c:339: error: static declaration of 'SpecType' follows non-static declaration Dependencies/zope.interface-ZopeInterface-3.0.1/zope.interface/ _zope_interface_coptimizations.c:73: error: previous declaration of 'SpecType' was here error: command 'gcc' failed with exit status 1 Since when do either Zope or Twisted require binary components anyway? --Dethe ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig

[Pythonmac-SIG] Frameworks which won't import
Let me try to rephrase my question. I have a framework which I can't import into PyObjC in the usual way. Since then I've tried various other frameworks I've found on my system, mostly embedded in application bundles, and some import but others do not. I'm not getting any information on *why* they can't be imported, even when I turn on debugging with the following lines before any attempt to load bundles. from PyObjCTools import Debugging Debugging.installVerboseExceptionHandler() Here are the questions: * What can I do to find out why a bundle wouldn't load? * Are there common, expected reasons for a framework bundle to not load? * Is there anything I can do about it? Now, as far as the Skype framework itself is concerned, I realized I'm using a Beta and downloaded the earlier, stable release, which does not have embedded frameworks.

Re: [Pythonmac-SIG] Simple Statusitem example
Replying to myself...
In another thread, Bob suggests waiting until the 29th to release
PyObjC 1.3.1, so I guess I have a little more time to work on this
example. Perhaps I'll keep this as a dirt simple example, and work up
a more realistic one with an icon, menu, and dialog. I had about an
hour last night to knock this together, which stretched out a little
longer because I'd never used NSTimer before.
Are there any examples people would like to see? What would actually
be *useful* to show in the status bar? ITunes and clocks have been
done to death, but I'm sure there's something that would be nice to
have which would make a good example.

Re: [Pythonmac-SIG] coding preference
That being said, I am hopeful about PyGUI, but it's a going to be at least another few years before it's as useful as wxPython (there isn't even a real Windows version yet!). After all, it took quite a few years for wxPython to become really usable. My mistake. I was under the impression that PyGUI had been abandoned. I will take another look. Maybe I was thinking of PIDDLE/Sping, which does appear to be abandoned. If PyGUI is still viable, I'll look into it and see if I can help out. In the meantime, wxPython (and probably PyQT, if the license works for you) is a pretty good option for cross platform code, and it's slowly becoming more Pythonic. I keep trying to like wxPython, I really do. It's just that its freaking huge, many of its widgets look like they were designed by children, and I find it really cumbersome to work with. The wx demo looks moderately OK on Windows, but pretty bad on OS X. I don't have any experience with PyQT, but prefer open systems to closed, given a choice. There are also a couple of pythonic wrappers for wxPython: WAX and PythonCard. I'm not fond of the wrappers around wrappers around wrappers approach, but if they work for you, who cares how many layers there are? I've looked at PythonCard, but you can't next objects, which rules it out for me (plus it's built on wx). I've been meaning to take a look at Wax to see if the API is worth porting to live on top of Cocoa, but I'll take another look at PyGUI first. --Dethe Choosing software is not a neutral act.
