PyOpenGL on OS-X ???
by David Wesley Dec. 26, 2002

Dec. 26, 2002

Hi all, Have any of you gotten PyOpenGL to work on OS-X? I've dowloaded the package, and am trying to compile it with distutils (setup.py), and have gotten farther along, but no success yet. The mac.cfg file looked like it was for OS < 10, so I created a darwin.cfg file that currently looks like this so far: [General] build_togl=0 gl_platform=AGL include_dirs=/usr/include:/usr/local/include:/usr/include/sys library_dirs=/usr/lib:/usr/local/lib ; a sys.pathsep separated list of the libs needed when linking GL [GL] libs=gl ; a sys.pathsep separated list of the libs needed when linking GLU ; the GL libraries are included automatically [GLU] libs=glu ; a sys.pathsep separated list of the libs needed when linking GLUT ; the GL and GLU libraries are included automatically [GLUT] libs=glut The other change I made was putting in a symlink from: /usr/local/include/GL to /System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/ because the source include files like this: #include GL/gl.h and gl.h and friends live in that Framework directory. I also got an error when it couldn't find malloc.h, so I added: /usr/include/sys to the include_dirs (see above) Now it can find malLoc.h, but I'm getting parse errors in that file, Which seems very odd. any help would be great, dave

"no codec search functions registered" when /usr/bin/ in PATH
by Ivan Kozik Dec. 24, 2002

Dec. 24, 2002

Hello, Right now I'm using the Python version built by apple (anyone know which one this is?). It almost works great (even executes Resources/__main__.py) in my .app bundle, but the problem is that I get the error message: LookupError: no codec search functions registered: can't find encoding when I open my program with /usr/bin in the $PATH variable. For example: '/usr/bin/open -a ProgramName' does not work, while 'PATH="" /usr/bin/open -a ProgramName' does work. Double-clicking in the Finder does not work either. I later discovered that this problem is not directly related to that "/usr/bin" is in the PATH, but that "/usr/bin/python" exists. After I renamed the "python" link to "python-bak" in /usr/bin, the program started even when /usr/bin was in the $PATH. I can't distribute it as it is because I am sure many people will have a python in /usr/bin. Since this solution *almost* works for me, I really wouldn't like to go to something else, but if I have to, I'm ok with that. Is there any way I can get PATH="" without a wrapper script in my .app bundle? I have also tried compiling the standard Python distribution with --enable-framework --enable-toolbox-glue but when I put it in my bundle, it doesn't seem to like the -psn junk the Finder and 'open' passes to it: file | -] [arg] ... Try `python -h' for more information. Unknown option: -p The standard python distribution also seems to ignore the code in Python/Mac/. I have also tried MacPython, but I really didn't like it. It's a rather ancient-looking solution for me. Any help would be appreciated. Thanks, Ivan

ANN: PyObjC 0.8
by Bill Bumgarner Dec. 23, 2002

Dec. 23, 2002

PyObjC version 0.8 is now available for download. See... http://pyobjc.sourceforge.net/ ... for more information. The installer package includes a Project Builder project template for easily creating new Cocoa-Python projects and a slew of examples. Alternatively, the developer can choose to develop applications without using Apple's developer tools. Full support for Interface Builder documents is included. The PyObjC Python module provides a feature complete bridge between the Python programming language and Objective-C. With PyObjC, it is possible to transparently message Objective-C objects from Python and Python objects from Objective-C. Objective-C objects can be subclassed from within Python. Support is also included for using the various functions, enumerated types, and global variables found throughout the Objective-C framework. References to python dictionaries pass into Objective-C act like a well behaved member of the NSDictionary class cluster. Likewise, Python List references behave like a member of the NSArray class cluster. Strings are transparently converted to the native type. NSArray and NSDictionary references passed into Python behave like native Python lists and dictionaries; including the ability to enumerate either using the 'in' operator and to slice NSArray and NSMutableArray instances. PyObjC fully supports creating full featured Cocoa applications written in pure Python. There are aspects of PyObjC that are more powerful than Cocoa in pure Obj-C (the ability to automatically define classes/outlets based on the contents of a NIB file, for example). PyObjC requires OS X 10.2 or greater. 10.1 support is possible and will likely happen soon-- contact me if you need 10.1 support and are willing to do a bit of grunt work to generate the appropriate files (easy to do-- just need a 10.1 development machine). The installer package is designed to work with the built-in Python provided in OS X 10.2. Source is included on the disk image and the pyobjc module works with Python 2.2 or greater as installed directly from the Python Source, with the MacPython packages, and with the Fink build of python. PyObjC also provides an awesome environment for exploring frameworks. The following transcript was copied out of a Terminal window-- it is an example of working directly with the Objective-C runtime from Python within the terminal. >>> from objc import * >>> from Foundation import * >>> b = NSBundle.bundleWithPath_("/System/Library/PrivateFrameworks/ PBXCore.framework") >>> b.principalClass() <objective-c class PBXProducerTarget at 0xa9030034> >>> NSBundle.searchPathsForSupportFilesWithSubpath_("FooBar") ( "/Volumes/Data/Users/bbum/Developer/ProjectBuilder Extras/FooBar", "/Network/Developer/ProjectBuilder Extras/FooBar", "/Developer/ProjectBuilder Extras/FooBar" ) >>> PBXProject = lookUpClass("PBXProject") >>> p = PBXProject.projectWithFile_("/Developer/Examples/AppKit/TextEdit/ TextEdit.pbproj") >>> p.targets() (<PBXApplicationTarget:0x00a76830:6FE2093EFE93D5F211CA2CEA:name='TextEdi t'>) >>> p.buildStyles() ( <PBXBuildStyle:0x00a77d30:011ADBA3FF9FD52E11CA0C5D:name='Development':bu ildSettings.count=2>, <PBXBuildStyle:0x00a82180:011ADBA4FF9FD52E11CA0C5D:name='Deployment':bui ldSettings.count=1> ) The version # of 0.8 indicates that documentation is lacking, unit tests are incomplete and there may be a bug or two lurking within. In practice, the module has proven to be very stable and to allow for the development of extremely complex Cocoa projects in pure Python or a mix of Python and Objective-C.

python + code double-clickable .app bundle?
by Ivan Kozik Dec. 22, 2002

Dec. 22, 2002

Hello, I am trying to combine the python interpreter and a python source code file into a .app bundle on Mac OS X 10.2. The only way I know of starting it now is: open -a python code.py (which is obviously not a good solution). Since the python interpreter requires an argument to execute something, I tried to replace the main binary with a compiled C executable (in the .app bundle) that executes the python interpreter with the source code as an argument. (The finder and 'open' executes the binary in MacOS/ with the full path, so I can easy chdir() to this directory and run an executable): #include <stdio.h> main(int argc, char **argv) { char *loc; char *p; loc = argv[0]; if (p = strstr(loc, "MacOS/ProgramName")) strcpy(p, "MacOS/"); chdir(loc); system("exec ./python ./sourcecode.py"); } I have tried this program with the "exec" in the system() and without the "exec" too. The problem is that my program uses Tkinter, and whenever i click on or try to move the window with my "solution", I get: SetFrontProccess failed,-606 (in the console). I'm guessing this problem appears because the new python process has a different PID from what the Dock and Finder expects. This problem did not appear when used 'open -a python sourcecode.py'. I have also tried modifying the python source code (Python-2.2.1/Mac/Python/macmain.c) to run my source code file at startup (without an argument) but I failed (I barely know C and how the python internals work). My question is, is there any way to run the python program in a .app bundle without an argument to the source code? (and have the mac os x windowing manager properly recognize my window)? Thanks, Ivan

Editors -- backspace = 4 backspaces
by Russell E Owen Dec. 21, 2002

Dec. 21, 2002

Pepper has recently come alive again and it can do the sensible thing with spaces as tabs. Contact "J. Todd Slack" <jason(a)digitalwandering.com>; he bought it from the original developer to bring it back to life. I have to say, I've stuck with tabs myself (using a tab width of 4). I suppose I may get in trouble someday, but it's easy to switch back and forth. It's funny how history controls us; if the original VT100 had used a tab width of 4 instead of 8 we'd probably all be happily coding with tabs. Happy holidays, all. -- Russell

workaround for webbrowser bug
by Russell E Owen Dec. 20, 2002

Dec. 20, 2002

I earlier reported the bug that the webbrowser module cannot reliably be used to open html files on the local computer (file:// links) in a browser. The files's creator is used to open the file (instead of the user's default web browser) and anchors are ignored. I've since learned a few useful things: - This is a known bug in MacOS X. That doesn't mean they'll fix it, but at least it has a tracking number. - The problem of opening the file with the wrong application is easy to work around: simply delete the file creator and type (using XRay or any such program). Then the default web browser is used to open the file. If you're used to double-clicking the file to edit it, this is a bit of a pain, but it's much better than nothing. To work around the anchor problem, I ended up using fairly small html files. Thus on the Mac version of my application help doesn't work quite as well as it might, but it still is reasonable. -- Russell

newbie osx question
by bsmith Dec. 20, 2002

Dec. 20, 2002

my first post so bear with me. i just started researching and reading about python a few weeks ago. it works great with IDLE on a linux box i have, but on my ibook i've having issues and was hoping to find some help here. my background is not that of a programmer, python is my first stab at getting into programming. my background is in audio/video development for the web and in professional sound recording. please keep this in mind when answering. i've been running basic python scripts (hello world and some other starters) in the terminal with no problem. when i save the code out as a .py file and try and 'run in terminal' from bbedit, i get '[bsmith:~] bsmith% /usr/local/bin/python '/Users/bsmith/pyscripts/dice.py' /usr/local/bin/python: Command not found. [bsmith:~] bsmith% ' when i do 'which python' i get 'usr/bin/python'. i have the developer tools installed so i would think it would install correctly. perhaps i have to change something in bbedit to make it look in the correct location?? i guess i'm just looking for tips on what apps are best for actually executing scripts on mac osx. any tips would be great. thanks in advance for putting up with the questions of a new guy. blake
