by Arthur Elsenaar Aug. 25, 2005

Aug. 25, 2005

Hi, trying to install PythonCard on OS X 10.4, but running into an import problem. I installed python2.4.1, wxPython2.6, TigerPython24Fix and TigerPython23Compat from Bob's packages page and added /usr/local/bin to my path. Python2.4 runs fine and I can import wx fine, but not pythoncard.. anyone know what can be wrong? Thanks, Arthur.

SciPy installer for Panther Python, anyone?
by Just van Rossum Aug. 12, 2005

Aug. 12, 2005

I'd like to quickly evaluate SciPy for a project, but I can't seem to find a binary distribution for 10.3's Python anywhere. Am I not looking hard enough? Tried to build from the source but the amount of dependencies for building it makes this not a viable option right now. Just

ANN: Boa Constructor for OS X available
by Kevin Walzer July 7, 2005

July 7, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Boa Constructor is now available for Mac OS X. Boa is a cross-platform Python IDE and wxPython GUI Builder. It offers visual frame creation and manipulation, an object inspector, many views on the source like object browsers, inheritance hierarchies, doc string generated html documentation, an advanced debugger and integrated help. This is the first version of Boa Constructor (O.4.3) to be distributed as a Mac-native application. Boa Constructor requires the installation of MacPython 2.4.1, wxPython 2.6.1, and Mac OS X 10.4. It is extremely unstable on earlier versions of Python/wxPython and has not been tested on an earlier version of Mac OS X. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCskxiJmdQs+6YVcoRAmXHAJ43146ihx3YewreeGtrLz5US/jnZwCfUHf4 rr+88Q+W3Uvb0kWVLXxVFE4= =Xc0/ -----END PGP SIGNATURE-----

NSMovieView question
by Jared Barden July 1, 2005

July 1, 2005

Hello all, If I'm using an NSMovieView to play a given movie that is let's say 5:00 long, how do I tell the NSMovieView to go to 4:45? I've been looking around and haven't found a good answer yet. All help appreciated, Jared Barden Wilcox Development Solutions http://www.wilcoxd.com

Python code in Objective C
by Robert Brown June 30, 2005

June 30, 2005

I've got an object written in Python (descended from NSObject using PyObjC) that I'd like to have access to in Objective-C. There's an example where some Python code is packaged as a plugin, then loaded in an Objective-C app, but it only ends up specifying one of the objects instantiated in the nib. How would you go about using the Python objects directly, like you would a framework, for instance? Thanks, Robb --------------------------------------------------- Robb Brown Seaman Family MR Research Centre Calgary, Alberta, Canada

Problem with pygame on Mac
by Quentin DECAVEL June 28, 2005

June 28, 2005

This is a follow-up of the thread "Problem with a py2app bundle". I downloaded the latest pygame version from CVS (1.7.1 on version.py), and compiled and installed it without any problem (I have every dependency, SDL... and smpeg). Here is the lines in Setup.in about the movie modules (movie is not commented, movieext is commented out): #the following modules are optional. you will want to compile #everything you can, but you can ignore ones you don't have #dependencies for, just comment them out imageext src/imageext.c $(SDL) $(IMAGE) font src/font.c $(SDL) $(FONT) mixer src/mixer.c $(SDL) $(MIXER) mixer_music src/music.c $(SDL) $(MIXER) surfarray src/surfarray.c $(SDL) $(NUMERIC) sndarray src/sndarray.c $(SDL) $(NUMERIC) $(MIXER) movie src/movie.c $(SDL) $(SMPEG) #experimental new movie movie. requires libavcodec and libavformat. #add any necessary compile flags to this line and uncomment. #movieext src/movie.c src/ffmovie.c $(SDL) -lavcodec -lavformat I then tried the following script, testmovie.py, that is supposed to load a movie: import pygame from pygame.display import flip from pygame.locals import * pygame.init() screen = pygame.display.set_mode((640,480)) pygame.mixer.quit() movie = pygame.movie.Movie("chamber.mpg") movie.set_display(screen, (0,0)) movie.play() movie.set_volume(1) flip() while 1: if not movie.get_busy(): break time.sleep(0.1) Launched with the command "/usr/local/bin/pythonw2.3 testmovie.py", this crashed before the movie was loaded, and here is the terminal output: testmovie.py:8: RuntimeWarning: use movieext: No module named movieext movie = pygame.movie.Movie("chamber.mpg") Traceback (most recent call last): File "testmovie.py", line 8, in ? movie = pygame.movie.Movie("chamber.mpg") File "/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/site-packages/pygame/__init__.py", line 52, in __getattr__ raise NotImplementedError, MissingPygameModule NotImplementedError: movieext module not available How is it possible that pygame, without being compiled with the movieext module, is still asking for it when a movie is loaded ? Is there any way to correct this behavior, or at least to trace the problem (I cannot get any more information than what the terminal gives me) ? Thanks in advance

OS X C API bug?
by Gary Robinson June 28, 2005

June 28, 2005

Hello, The attached file contains a c module with 4 versions of the same extremely simple function. All they do is return a float double to python. The zip also contains the setup.py to build it. On Windows I can import the module into Python and run all of them successfully. But on OS X Panther with XCode 1.5 installed, the first 3 work and the last one causes a bus error. There is no obvious reason why it should do so. (At least not to me or the others who have looked at it.) Here's the output on Panther: >>> from check import * >>> fun0() 411.0 >>> fun1() 534.30000000000007 >>> fun2() 411.0 >>> fun3() Bus error I originally reported this on the C++ sig's mail list. They suggested I try dev-python. Scott David Daniels on that list helped me refine some test cases and verified that they all worked on Windows. He suggested I try mac-python next, so here I am. We're thinking it may be compiler-related. The code follows: #include "Python.h" static double value = 411.0; static PyObject * fun0(PyObject *self, PyObject *args) { if (!PyArg_ParseTuple(args, "", NULL)) return NULL; return Py_BuildValue("d", value); } static PyObject * fun1(PyObject *self, PyObject *args) { return Py_BuildValue("d", 1.3*value); } static PyObject * fun2(PyObject *self, PyObject *args) { return PyFloat_FromDouble(value); } static PyObject * fun3(PyObject *self, PyObject *args) { return Py_BuildValue("d", value); } static PyMethodDef TestMethods[] = { {"fun0", fun0, METH_VARARGS, "Read args and return value"}, {"fun1", fun1, METH_VARARGS, "Return value multiplied inline by 1.3"}, {"fun2", fun2, METH_VARARGS, "Return value using PyFloat_FromDouble"}, {"fun3", fun3, METH_VARARGS, "Return value using Py_BuildValue without reading args -- causes bus error on OS X Panther with XCode 1.5 installed"}, {NULL, NULL, 0, NULL} /* Sentinel */ }; PyMODINIT_FUNC initcheck(void) { PyObject *module; module = Py_InitModule3("check", TestMethods, "extension module with three functions."); if (module) { PyModule_AddStringConstant(module, "__version__", "0.02"); } } Any help or insight would be most appreciated.

Re: [Pythonmac-SIG] [Python-Dev] Possible C API problem?

I don't feel confident in a workaround unless someone understands the details -- otherwise the "workaround" may really be temporarily hiding an ongoing intermittent problem... That's why I'm very interested in getting an answer to this. But based on other people's testing today, I'm coming to feel that that possibility is fairly unlikely.

Re: [Pythonmac-SIG] Eclipse + PyDev

This pretty much echoes my own experience. I use Eclipse+PyDev on an old 333 MHz G3 laptop and a Quicksilver G4 desktop. It's slow to start (about 30s on both machines), but once it's up it runs just fine. I've only been using it for a few weeks but I'm pretty close to hooked. I did take a brief look at Wing IDE and was impressed. But what attracts me to Eclipse is that I'm working on projects with C and Fortran extensions. My understanding is that other Eclipse plugins (e.g. Photran for Fortran) will let me work with those files within Eclipse as well. And I'll be able to also work on HTML & JavaScript in support of these projects in the same IDE. (I hasten to add that I haven't tried any of this yet.) I need to do this on both Mac and Linux (FC3) machines. The only other environment I found that offers this combination of both cross-platform and cross-language support is JEdit (with appropriate plugins). I tried JEdit for a while, but Eclipse's latest incarnations are much more Mac-like on the Mac and Linux-like on my FC3 box, probably because Eclipse uses custom GUI tools, rather than relying on Java's standard GUI tools. I have also tried Eclispe+TruStudio Foundation. While TruStudio looks promising, they have a ways to go (their editor plugin doesn't even correctly handle indentation). It's a 1.0 release, but I'd say that designation is premature. But it's probably worth keeping an eye on TruStudio. -Tom Loredo
