I develop a standalone cross-platform python/wxpython app on linux and I have exactly the same concern (on ubuntu). I would make sure that there is no simple solution to use py2app on linux to build the comprehensive bundle (with a python interpreter and wxpython in it) that I can send to mac os x users. I planned to use one (not two) mac to test the bundle anyway and I could use it to run py2app. My concern is that I need to test the bundle on this mac afterwards and I am afraid that my (wx)python installs will false the test. Then my question: what is the best way to install python and test afterwards ? different users, uninstall everything ... how ? Thx in advance for your ideas, suggestions ... KB

building bundles with setuptools, py2app, 64-bit python 2.6
by Michael VanLandingham Aug. 25, 2008

Aug. 25, 2008

I recently built a Python64.framework & interpreter from the 2.6 sources (using Ronald O's recently recommended build settings), and then build PyObjC. Because I got an error running PyObjC's build script, (setup tries to pull down an URL that's non-existent: http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c8-py2.6.egg), I built and installed setuptools from svn.python.org with/for my 4-way fat python build. I need to create 64-bit compatible versions of some PyObjC bundles that we're using. However, when I tried to use it, like this: $ /usr/local/python64 setup.py py2app I got the error below. Which points to what looks like a problem in setuptools. Can anyone offer any advice here? Maybe I need a less cutting edge version of setuptools? Is anyone using 64-bit python, PyObjC to build 64-bit or 4-way fat apps or plugin bundles, and if so, how? Thanks in advance, Michael here's the traceback: ------ running py2app Traceback (most recent call last): File "/Volumes/Sandbox/pyobjc/py2app/py2app/build_app.py", line 579, in _run self.run_normal() File "/Volumes/Sandbox/pyobjc/py2app/py2app/build_app.py", line 631, in run_normal mf = self.get_modulefinder() File "/Volumes/Sandbox/pyobjc/py2app/py2app/build_app.py", line 539, in get_modulefinder debug=debug, File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/find_modules.py", line 255, in find_modules find_needed_modules(mf, scripts, includes, packages) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/find_modules.py", line 176, in find_needed_modules mf.run_script(path) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 369, in run_script self.scan_code(co, m) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 610, in scan_code self._safe_import_hook(name, m, fromlist) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 540, in _safe_import_hook mods = self.import_hook(name, caller) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 380, in import_hook q, tail = self.find_head_package(parent, name) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 419, in find_head_package q = self.import_module(head, qname, parent) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 493, in import_module parent and parent.packagepath, parent) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 680, in find_module fp, buf, stuff = find_module(name, path) File "/Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py", line 114, in find_module if isinstance(importer, pkg_resources.ImpWrapper): AttributeError: 'module' object has no attribute 'ImpWrapper' > /Volumes/Sandbox/pyobjc/modulegraph/modulegraph/modulegraph.py(114)find_module() -> if isinstance(importer, pkg_resources.ImpWrapper): (Pdb) pkg_resources <module 'pkg_resources' from '/Library/Frameworks/Python64.framework/Versions/2.6/lib/python2.6/site-packages/setuptools-0.7a1dev_r65222-py2.6.egg/pkg_resources.pyc'> (Pdb) list 109 for entry in path: 110 importer = pkg_resources.get_importer(entry) 111 loader = importer.find_module(name) 112 if loader is None: continue 113 114 -> if isinstance(importer, pkg_resources.ImpWrapper): 115 filename = loader.filename 116 if filename.endswith('.pyc') or filename.endswith('.pyo'): 117 fp = open(filename, 'rb') 118 description = ('.pyc', 'rb', imp.PY_COMPILED) 119 return (fp, filename, description) (Pdb)

catching the Cmd+Q event
by David Warde-Farley Aug. 25, 2008

Aug. 25, 2008

Hi all, I was wondering if anyone knew of a way to catch Cmd+Q in a threaded wx/Tkinter/etc. event loop. The reason is that ipython ( http://ipython.sourceforge.net/ ) supports several plotting toolkits for interactive data analysis, however if you habitually hit Cmd+Q to close the window, things get all screwy. Essentially the event somehow blocks and the thread goes stale. Ideally, we'd like to mask (i.e. ignore) it, or somehow map it to the close window action. Is there any way to do this, at all? (ideally it wouldn't involve PyObjC, but realistically I think it most likely will). Thanks, David

controlling Mail.app and GnuPG
by Henning Hraban Ramm Aug. 24, 2008

Aug. 24, 2008

The issue was raised before, but I didn't find any hints how to solve my little problems... BTW, this is framework Python 2.5.2 on OSX 10.5 It is known that the public API of Apple's Mail.app is incomplete and buggy, therefore stuff like the GnuPG plugin stay in eternal beta (and just don't work on my German system - I guess i might my a language problem). Anyway. I tried to write a little helper for GPG encrypted mails - before I dragged the "encrypted.asc" attachment in some folder, called gpg in the bash, copied the decrypted text back in my reply window and replaced all the MIME codes with proper umlauts etc. (I can encrypt the mail via S/MIME, my friend can decrypt that, but didn't get S/MIME encryption to work in her Linux Thunderbird or Evolution, so she sends GPG encrypted...) So, my script gets the selected message in Mail.app... * issue (1) [appscript syntax for Mail.app]: I can list the attachments with appscript, but I didn't find a way to save them or to access them as files. Thus, I read the source of the message. * issue (2) [dysfunctional email module]: The email module (std lib) claims to be able to decode multipart MIME, but finds only 1 part in that text that consists of at least 2 attachments. So I cannot use that. Thus, I extract the "PGP MESSAGE" part using regular expressions. In the cheeseshop there are two modules to access GnuPG: http://pypi.python.org/pypi/pygpgme/0.1 http://pypi.python.org/pypi/GnuPGInterface/0.3.2 The first is from 2006 and seems unmaintained, the latter has a really ugly, un-pythonic syntax. I could also call gnupg via system calls. I don't care about security issues on my own system, otherwise I could just forget any approach, for I must store my passphrase anywhere, and if the decrypted text stays in my bash history, it isn't safe anymore. Ok, so I decrypt the encrypted part via GnuPGInterface (you must open and close 3 different file handles for that). The decrypted text still contains header information and signature and is in MIME encoding (i.e. "quoted-printable"). Using regular expressions I look for the MIME boundary string and extract the message part. The headers tell me, it's in ISO-8859-15 encoding (= latin-9), same as 8859-1 (= latin-1) plus Euro sign. unicode(text, 'quoted-printable') isn't possible, because it returns string, not unicode. Of course - "quoted-printable" is no encoding by itself, but needs an encoding defined. unicode(text.decode('quoted-printable'), 'iso-8859-15') should work. * issue (3) [missing encoding in Python]: Python doesn't know ISO-8859-15! -- Hey, that exists since 1999! So I can't just use the detected encoding, but hardcode 'latin-1' instead (should usually fit my needs, but isn't generally usable), i.e. unicode(text.decode('quoted-printable'), 'latin-1') Now I've finally the readable text of the message in proper unicode. Let's make a reply mail: reply = message.reply(opening_window=True) I don't understand why usually a message window is invisible, but anyway, that works so far. reply.content.set(decrypted_text) Doesn't work: If I try it in PyCrust, the new text appears above the initial content, can't delete that. In my script I get only a CommandError: CommandError -10000: Apple event handler failed. Failed command: app(u'/Applications/ Mail.app').outgoing_messages.ID(409455472).content.set(u'bla') Despite that error, when I close Mail.app, a new message containing my text appears, i.e. instead of setting the content of my previously created reply mail, it makes a new outgoing message in the background. * issue (4) [appscript syntax for Mail.app]: How can I set the complete content of a reply message? Your help on any of that issues is appreciated! Greetlings from Lake Constance! Hraban --- http://www.fiee.net https://www.cacert.org (I'm an assurer)

"Best" Mac Python under Leopard?
by Andrew Jaffe Aug. 24, 2008

Aug. 24, 2008

Hi All, I know this comes up every few months, but there is never a definitive answer given. The short version is: what is the best Python to use under Leopard? The longer version is: What is the best Python to use under leopard if: - I want to use PyObjC - I want to use more recent versions of packages like numpy that come installed - I want to use ipython and readline - I think I want to be able to use more recent versions of Python (and I certainly will once 2.6 comes out). Currently I am using a framework build of 2.5.1 (since I was doing so under Tiger) but this seems to be a problem for pyobjc. It would also be great if there were a single place on the web where this is answered; if you search -- even with this group -- you get very different pieces of advice. Yours, Andrew

what is the best way to export an image of the GUI that Tkinter makes? maybe: Python Image LIbrary(PIL) py2svg: http://wmula.republika.pl/proj/canvas2svg/canvasvg.py Ideally I would like to end up with a tif file equivalent to a screen grab of the UI that Tkinter made. Possible options would include various sizes?

The most important things that should be done for PyObjC itself: 1) Modernize all sample projects. A signficant subset of the examples in the repository still use PyObjCTools.NibClassBuilder. That module is deprecated and shouldn't be used in new code (and doesn't work with IB3 at all), all examples should be modified to work without NibClassBuilder. This means: - Add explicit base classes instead of NibClassBuilder.AutoBaseClass - Add outlet definitions (objc.IBOutlet definitions) - Add @objc.IBAction decorator to actions (needed for IB3) All examples should have a "readme.txt" and a "summary.txt", the latter is used on the website in the list of examples. 2) There are a number of examples in the pyobjc-core project, those should be moved to the most appropriate pyobjc-framework-* framework wrapper 3) IMHO there should be sample code for all wrapped framework, if only be translating an existing (Objective-)C example 4) All metadata (bridgesupport files) should be verified, see below 5) (very hard): Libffi is broken on PPC64 To be precise: the basic functionality works, but calls through libffi break Objective-C exception handling. This totally breaks PyObjC and fixing that probably requires help from a compiler guru. My gut fealing is to ignore PPC64, fixing libffi is too much of an effort. 6) Port PyObjC to OSX 10.4. This should be fairly easy once step 4 is finished, the code already contains the hooks that are necessary for this port and has worked on 10.4 in the past. 7) Move pyobjc-core/Lib/objc/test to pyobjc-core/PyObjCTest. I've already moved the tests for framework wrappers out of the package that is installed by distutils, the same should be done for pyobjc- core. This can wait until a later release. Py2app also needs some loving (proper egg support, testsuite), but that can wait until after a release of PyObjC itself. > > >> I'm very, very slowly adding unittests for all global functions, >> and other interesting items, in wrapped frameworks because that's >> the only way to be sure that the wrappers work as advertised.

I could put in a bit of time on some of the > mechanical tests if I had a place to find the checklist. There is no list, at least not outside of my head. I've just commited the current state of the tests for the Cocoa frameworks, see <https://svn.red-bean.com/pyobjc/trunk/pyobjc/pyobjc-framework-Cocoa/PyObjCT… >. Adding tests for other frameworks should be a lot easier, most of them should contain almost no entities for which tests are needed. I'd like to see tests for all: * C functions (CGContextCreate, ...) * All structs: are the right fields present * All methods that have a custom wrapper (that is, anything with a manually written wrapper in the Modules directory) * All methods with pointer arguments The tests should check if the Python wrapper works and has the right interface (as described in the PyObjC intro.txt document). Testing if the framework functions correctly is not a goal, unless a OS bug affects the functioning of PyObjC itself. During this task we might run into API's that we don't want to support, or cannnot support, in Python. Those should be documented. I'm currently also adding tests that check the presence of global variables (and values of enums), but those are less important. Ronald

Re: [Pythonmac-SIG] applescript bundle droplet
by beau Aug. 21, 2008

Aug. 21, 2008

I am using apple script to create a droplet that basically lets you pass the incoming file as an argument to a bundled python script. The python script then displays the output in a UI made with Tkinter. Questions: 1. is it possible to quit the apple script before python sends it's exit code? 2. Is there anyway to suppress the console so only the UI shows up on screen? 3. How can I change the name of the title on the menu bar from python to my app's name?
