Graphing capablility in Mac Python
by Anthony M. Ingraldi Aug. 23, 1998

Aug. 23, 1998

Hello, Is there a module available that will provide routines for creating simple line graphs and scatter plots? I was thinking of using AppleEvents to send data to KaleidaGraph or some other package but that seems sluggish. Another alternative would be to use a Canvas widget from Tk. I would prefer to use a module designed specifically for plotting rather than writing one via Tkinter. -- Tony Ingraldi | e-mail: A.M.INGRALDI(a)LaRC.NASA.GOV NASA Langley Research Center | Mail Stop 267 | Phone : (757) 864-3039 Hampton, VA 23681-0001 | Fax : (757) 864-7892 _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________

Python as CGI
by William Burrow July 31, 1998

July 31, 1998

I am attempting to port some Python files from Unix to a Mac web server. I am interested in knowing how one sets up a Python file for execution as a CGI program. Attempts to build the .py file as an Applet fail. Any clues? -- William Burrow, VE9WIL -- New Brunswick, Canada o Copyright 1997 William Burrow ~ /\ ~ ()>()

Re: [Pythonmac-SIG] Suggestion for PythonMac-tutorial: droplets?

If I understand the term "droplet" correct, an applet on which you can drop files, then every Python applet is a droplet. By default every applet will accept files of any type, and they'll all end up in sys.argv. If you want to change the former you can supply your own resource file with a different BNDL resource, if you want to change the latter, and do your own startup AppleEvent processing (for instance because you want to catch a GURL startup event) you drop your applet on EditPythonPrefs and set the "no argc/argv" and preferrably "no starup option dialog" options. Do people feel that this behaviour deserves special mention in the documentation? -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Pmw on the mac?
by James Boyle July 29, 1998

July 29, 1998

I'm using Pmw on an SGI and a Sun and everthing works quite well. I often do python work at home on my mac(G3), but Pmw appears to have some serious problems on that platform. I saw in the archive of this group that these Pmw problems have been noted before. Is anyone working on Pmw for the Mac or is it related to fundamental Tk shortcomings? I'm not fussy about the 'look and feel', the cross platform aspect is more important. Thanks for any information. Jim

Re: [Pythonmac-SIG] OSAm leaking?
by Sean Hummel July 29, 1998

July 29, 1998

I too have not noticed any memory leaks. Although one thing to be aware of is that OSAM does not own the string you pass in for the script. This means it doesn't delete string, and that you must. Another interesting tidbit is that each time you run OSAm is that the OSA component gets loaded and unloaded. This causes some fragmentation of the heap, but what can you do? >At 10:05 AM -0700 7/24/98, Jay Painter wrote: > > >> I usually give about 15-25 MB of memory to my >>Python scripts, and I havn't noticed a problem, > >The applet I'm having the problem is intended to be run continuosly since >it is a task scheduler.

Diff utility
by Jason Harper July 29, 1998

July 29, 1998

Does anyone know of any Unix-compatible diff tool for the Mac? I have some ideas for some enhancements to the Python core, but I have no practical way of submitting them. Searching the Web has turned up various links, none of which have lead anywhere useful. Jason Harper

Suggestion for PythonMac-tutorial: droplets?
by Wolfgang Keller July 29, 1998

July 29, 1998

Hello, there doesn't seem to be any example available of how to write a droplet in Python. Is this possible at all? If so, is there an example somewhere? How about including it in the demo folder of the Python distribution?

Apparently "Midishare" has this functionality. I'm trying to grok their documentation; unfortunately much of the example code is in Pascal and pretty much all of the comments are in French. The guy that wrote OMS is in PSA (Doug Wyatt). It would be great if he did a Mac/Windows PyMidi, no? Bill Dozier Mortgage Physicist

The easiest would probably be to use unix diff (but do use diff -c in that case). CodeWarrior has a diff since the previous version, but I have no idea whether the diffs are exportable and useable... -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

The other stuff like OMS is just as bad, as far > as I understand it. As it was just pointed out to me that there are people on the list involved with implementing these I guess I should qualify these statements:-) What I meant was: both OMS and quicktime midi assume that the program using them is in charge of its own timing, so it can give the right quicktime calls or send the right OMS messages at the correct time. They unfortunately don't seem to have an interface that allows you to stuff a number of time values and command/arguments into a buffer and say "here, go do these and tell me when its done", such as the Sound Manager has (and, to a lesser extent, QuickTime for movies, where you only have to call MoviesTask once in a while and that's it). But, of course, if the functionality is in there somewhere and I've missed it I will be the first to applaud whoever corrects me:-) -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm
