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 _______________

FWD: Find File bugs and a Trash Icon emulation in Python. (send to comp.sys.mac... )
by Steven D. Majewski Jan. 28, 1998

Jan. 28, 1998

I only recently ran into the Find File bug in MacOS-8 (unfixed in 8.1) where you cannot drag multiple files onto the desktop or into the trash. ( I'm quite amazed that Apple could leave such a glaring User Interface but unfixed, but that's another matter! ) After I found this note at MacFixit about the 8.1 update: <http://www.macfixit.com/reports/macos8.1.shtml> | Dragging | | Rich Bottiglieri writes: "The bug with dragging multiple files to the trash | from the Find File window has not been fixed with Mac OS 8.1. You still have | to drag them one by one, or create an alias of the trash and drag them there. | On the plus side, however, the annoying bug with dragging and dropping text | clippings into some applications (notably SimpleText) appears to have been | fixed." But before I found the original account (which gives a bit more explaination): <http://www.macfixit.com/reports/macos8.0.shtml> |Find File glitch Robb Albright writes that Find File in Mac OS 8 "cannot |operate on multiple items in Find File's Results window. Specifically, |apparently due to changes in Finder's AppleScript/Apple Events, if you |perform a find, select more than one item in the results window, and try to |do something with it (i.e., drag to trash, drag to Desktop, etc.), the items |will bounce back to the Results window. These operations work fine on a |single item." Richard Hardy and others also reported this I tried or considered several workarounds: Strangely, dragging the items into a text editor does work. I had considered writing a program or script to take that list of files and trash them, however, the filename, size, type and date modified can all be pasted into an Text Editor (I tested Alpha), but that doesn't include the full pathname -- without that the rest of the info is pretty useless. The fact that this feature, however useless, works, while the usual drag operation doesn't had me thinking that perhaps this bug was a feature of some new changes to Drag & Drop support. I started reading thru the docs and Tech Notes (TN-1043 & TN-1085) to see if there was a mention of this problem. [ I tried a couple of searches at the apple web site for "Find File" and/or "drag", and this was the best I could find. I found no direct mention of the bug on Apple's site. ] However, after I got bored with reading Tech Notes, I though I'ld try something simple. A Mac Python applet (<http://www.cwi.nl/~jack/macpython.html> and <http://www.python.org/>) will turn files or folders dropped onto it into pathnames in the sys.argv list. I tried the following little test script, dropping it onto BuildApplet to turn it into a "droplet": from os import unlink def main( args ): n = 0 for filename in args: n = n + 1 print '[%3d]' % n, filename # for now, just print count and name # unlink( filename ) # to delete files use os.unlink import sys if __name__ == '__main__' : main( sys.argv ) This worked when I dragged one or several files from Find File onto the droplet, however it crashed when I dragged 400+. I thought at first that it might be due to the maximum number of args in Python (255), and was about to try rebuilding it with a heftier 1024 limit, but testing it in more detail, I found it worked for 50+ or 80+ files, but it crashed (or on two occasions, it did nothing and passed no args to Python) for the values I tried between 100 and 255. The Crash was always from a BUS ERROR in Find File. Anyone know what's going on with Find File ? -- Steve Majewski <sdm7g(a)Virginia.EDU> _______________ 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 _______________

There's a lot more in 1.5: OSA classes and such are supported in a way.

python and Frontier

has anyone worked on interoperation between Mac Python and Frontier. I'm just learning Python, but am experience with Frontier, and would love to be able to use it's outliner for Python script writing....it's a natural match for the language's use of indentation, etc. i have, however, had little luck deciphering Apple-Events in Python and need some direction on how to establish a link....i'd love to be able to send script with parameters from Frontier to Python and receive results. any ideas? links? tutorials?

Check the "about this mac" window to see whether the Python partition is indeed completely filled up (or almost filled up: the window isn't always completely up-to-date) when the error occurs. If so: give Python more space with the "info" dialog in the finder. -- 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 _______________ 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 _______________

malloc error
by Tasselli Marco Jan. 23, 1998

Jan. 23, 1998

hi everybody, I'm continuing my exaustive use of Python and its gdbm capabilities. I have many procedures tha access gdbm files now and it started giving the following error: "gdbm fatal: malloc error" The fact is that I could not track down this error which seems completely random and seems, apparently, correlated with the way gdbm is implemented. I'm using a version 1.4 of MacPython. DO you have any idea about this? Any suggestion for working it around?

Re: [PYTHONMAC-SIG] EOF ( ^D or ^Z ) on sys.stdin.read()

> This behaviour is caused by Sioux, indeed. I could probably fix it, if people > think it's important... Hmm, I just looked at it in an idle 5 minutes, and it is rather difficult to fix: the sioux console driver sets a hard eof flag on a low level. So I hereby retract the offer to fix it (unless people can point me to the right page in the C standard where it says that this behaviour is illegal, so I can send a bugreport to MW: I have this feeling that clearerr() should clear eof conditions too, but I haven't got a standard handy). -- 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 _______________ 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 _______________

EOF ( ^D or ^Z ) on sys.stdin.read()
by Steven D. Majewski Jan. 22, 1998

Jan. 22, 1998

Using Mac Python 1.5b3, A control-D or control-Z while reading from sys.stdin seems to exit Python. I tried wrapping it in a try/except and Editing the options to try to keep the window open, but it still quits immediately. Is this a SOUIX bug/feature ? How can you signal the end of text without exiting the interpreter? BTW: I just ran into the problem -- I'm amazed that I didn't run into it sooner -- that under OS8's ( and 8.1 ) you can't drag more than one item from FindFile into the trash! As you can drag the multiple selection into a text editor app, I was about to see if this would work with Python, however dragging it to Aplha, I see it does not include the full pathname with the filename, so that is a pretty useless way around the problem. Also it doesn't look that Python will accept the drop, so I suppose this is not a generic function of a text app, but must require Drag & Drop support. So the answer to the above is not going to help with the problem I was trying to fix anyway! ---| Steven D.
