Hmm, my guess would be either a bug in CodeWarrior, or (probably more likely) you using the wrong runtime library. Especially if you use C++ you have to be careful with which runtime library you use where, because the zero-overhead exception handling will fail otherwise. And you shouldn't use Python as an example, because it doesn't follow the rules (but gets away with it being a C program).

Getting Piddle to work with Python 2.2
by Louis M. Pecora April 19, 2002

April 19, 2002

(Sorry if you saw this on the Python NG. I've posted in a few places I thought I might get an answer. Thanks for your patience.) I have returned to Python after a year away (old version 1.52 on a Mac using sys 9.1). I upgraded to Python 2.2 and got messages that my old version of Piddle was deprecated. I downloaded the latest version and am stuck. After searching the documentation I cannot find how to install it other than the statment in the README.txt that says type in python setup.py install and go. That does nothing for me in the IDE on my Mac. I am probably missing something simple, but unless I get some plotting stuff running my return to Python will be short-lived. Can you tell me what I'm missing so I can install a new version of Piddle on my Mac? Thanks for any help. -- Cheers, Lou Pecora

Speed issues with Applet/Applications?
by Sean Hummel April 12, 2002

April 12, 2002

Hi, I wrote a script which allows me to decompress from a .ZIP file, and appropriately sizing names of files that are longer than 31 characters. However the problem I am encountering, is that when I run the script in the Python IDE, it runs at full speed. When I run the script as a standalone application or applet, then it runs VERY SLOW! I am using Python 2.1, and I am using running this script on a PowerG4. So I am wondering if someone else has had this problem when using the application or applet, and/or if there is a good solution to this problem.

MacPython 2.2.1c2 available
by Jack Jansen April 5, 2002

April 5, 2002

MacPython 2.2.1c2 is available through http://www.cwi.nl/~jack/macpython.html . There are two relatively major changes since 2.2.1c1: - The IDE module browser should now work on OSX! This shouldn't have broken the IDE on older systems, but you are cordially invited to test this. - Most toolbox modules now weak-link against InterfaceLib, making the modules importable on older systems that miss some of the newer functionality. This should finally make 2.2.1c2 run on MacOS 8.1 and later. But: you are cordially invited to test that this indeed works (if you have 8.1 or 8.6) and doesn't break anything else (if you have OS9 or later). OSX users who previously installed 2.2.1c1 may have to remove their Python preferences file. -- - Jack Jansen <Jack.Jansen(a)oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -

Fwd: Apple Design Awards Update: Open Source Category
by Jack Jansen April 3, 2002

April 3, 2002

Folks, Apple have just added a category "best open source product" to their yearly design awards. How about giving it a go and trying to win that award with Python? We have until April 5 to enter, which gives us almost 6 weeks. The question is: what would we need (that we don't have yet) to win, and can we do that in 6 weeks? Here's my list of things we definitely need: - The IDE (no idea how far along that is) - The OSA component (no idea how easy this would be to integrate. Actually, I have for the second time forgotten who did this! Sorry, please speak up!) - universal newline support (should be trivial to drop in) - Bells and whistles, such as BuildApplet, EditPythonPrefs and BuildApplication (but these should probably be built in to the IDE, not as separate apps) - A nice installer that also installs the /usr/local/bin symlinks for unix to use, etc. - Packaged documentation, preferably in a form that Apple Help can read (plus hooks in the IDE to get at the docs). - Consensus on how we're going to split the dual G4 we're going to win:-) I think what would make this a potential winner is that it covers three programming areas (unix scripts and CGI, Applescripting, standalone Mac development) and that it is the only tool that does all three. All competing languages cover only one or at most 2 of these areas (Perl: 1, Applescript: 23, Tcl/Tk: 13, Java: 13).

MacOS.Error exceptions
by Donovan Preston March 30, 2002

March 30, 2002

Hey everybody, As there is a discussion right now on Python-Dev about Exceptions (string exceptions and others) not inheriting from Exception, I thought I would bring up an issue about MacOS.Error here in Python-Mac first and gauge people's reactions. The issue is that MacOS.Error, which is raised as an exception from many of the toolbox modules, does not descend from Exception. In the pre-python 2.2 class-type model, I'm not sure it could have inherited from Exception, since it is defined in a C module; I'm wondering if it's possible now, and for the sake of consistency if we should try to make MacOS.Error descend from Exception? This definately surprised me the first time I encountered it; I was trying something like try: foo.SomeMacOSCall() except Exception, e: print "whoops, oh well" However, the MacOS.Error still made it through. I'm willing to explore what it would take to fix this if 1) someone tells me it's possible and desirable, and 2) someone points me in the right direction w.r.t. having something (a type? a class? a new style class also being a type...) that's defined in C descend from something else.

My Tk window appears, but when I click its "quit" button, the window doesn't go away. It stays hidden behind the PythonInterpreter.out window. It accepts some inputs (the "window shade" button works), but I don't see the print that is supposed to happen after return from mainloop(). I have to force-quit the interpreter; it won't quit voluntarily. After playing around, I did manage to get it to work. Kind of kludgy, though. When the program first starts, the Tk window appears in front, but at that point it doesn't seem to accept any input. I can't resize the window, for example. However, if I bring the PythonInterpreter.out window to the front, and then bring the Tk window back to the front, everything is fine. I can resize the window, and clicking the button makes everything terminate successfully. (Well, at least usually. Sometimes it still gets confused.

Numeric.py and CLAPACK?
by Louis M. Pecora March 29, 2002

March 29, 2002

Has anyone been successful getting CLAPACK working with Numeric Python ? I have the source and a codewarrior compiled library for CLAPACK, but I have not clue how to integrate the two and have the real CLAPACK replace the lite version that comes with Numeric.Py. I checked the docs, but found nothing. Maybe I'm overlooking something. Any clues greatly appreciated. -- Cheers, Lou Pecora

Getting an image into Piddle
by Louis M. Pecora March 29, 2002

March 29, 2002

I see that Piddle can display images (the .drawImage(image, x1, y1, [x2], [y2]) method). The image appears to be a PIL-compatible file. SO...how does one generate such an image? Let me give an example. I have a 2D data array of numbers representing intensity (keep it grey scale for now, say 0.0=white, 1.0= black, in between are shades of grey). How do I generate an image (say, halftone plot)? Any help appreciated as always. Thanks. -- Lou Pecora P.S. I've looked at the PIL info and it's really not clear.
