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 _______________

Thread support in Mac Python?
by Joseph J. Strout Oct. 23, 1997

Oct. 23, 1997

Can anyone brief me on the current status of thread support in Mac Python? IIRC, the last time I asked, they just plain didn't work -- but that was some time ago. If they're still not working, are there any plans or prospects for adding them in? (Doesn't the current MacOS have a Thread Manager or some such?)

MacPython 1.5a4 available
by Just van Rossum Oct. 15, 1997

Oct. 15, 1997

I've just announced a binary distribution of MacPython 1.5a4 to the PSA-members mailing list. If you are a PSA member, you'll know where to find it. If you're not, but feel like you could contribute to testing this release: convince me to send you the Secret URL.

Applications as shared libraries
by Steven D. Majewski Oct. 14, 1997

Oct. 14, 1997

FYI: There is a note on this in the "Targeting Mac OS" Code Warrior docs, under the heading "Applications as Shared Libraries" -- which sounds clear enough, but the two paragraphs under that heading I found rather confusing. But -- if anyone is interested: it is probably possible to build Python as an application without the PythonCore shared library and still link other DLLs to use the Python API routines. The trick is to load the application file into the DLL project, and to set the compiler for files of type 'APPL" to "PEF Import PPC" in the File Mappings preference panel. This seems to cause the library to resolve it's symbols from the application code. ( You also need to have set the application to export the needed symbols. ) [ I haven't done this with Python, but I've have with another program, so I'm quite sure it will work as described. ] I think the separate shared library is useful for applets and other uses, but perhaps this may be useful for someone who needs to produce an embedded app or some other case where you need to simplify the "shippables" . ---| Steven D.

Windows emulators on PC's
by dave＠zeus.hud.ac.uk Oct. 13, 1997

Oct. 13, 1997

Sorry not strictly mac python as such but I want to run the windows 95 python from my Mac : 240 Mhz 603e machine. Does anyone have any experience of doing this using the SoftWindows'95 or VirtualPC emulator? I want to do this for teaching purposes as students only have access to Unix version or PC version of Python and I want to check out any work that I do on a Mac first, before downloading to the students. I want to know if a) using PIL is feasible using this convoluted route ie gives adequate performance b) which is the best emulator.

Bits of MacPython 1.5a4 available
by Jack Jansen Oct. 10, 1997

Oct. 10, 1997

I've just announced a source distribution of MacPython 1.5a4 to the PSA-members mailing list. I've sent the various bits and pieces to Just, who should hopefully be able to turn that into a working binary distribution, because I'm off to Egypt and Jordan for 5 weeks. If you're not a PSA member but you think you could contribute to testing this release: convince Guido or Just or so to tell you the URL of it.

Python and Igor
by Rob Managan Oct. 9, 1997

Oct. 9, 1997

This is a notice that I have started to look at building a Python module that will plot using Igor. This effort will necessarily be limited to Macintosh and Windows. Right now I am using the PPC (program to program comm) interface on the Macintosh. I have the C part mostly done (with Swig) but need to add array support. More work is required in python code to prepare the data and set up the connection to Igor. I would love to collaborate with anyone who has time and interest in this. *-*-*-*-*-*-*-*-*-*-**-*-*-*-*-*-*-*-*-*-*- Rob Managan mailto://managan@llnl.gov LLNL ph: 510-423-0903 P.O.

It is included in the standard distribution, which is why you don't see its name come up often. The reason it's in the standard distribution is of course that I wrote it, with some help from Sjoerd:-). I still use it a lot, and its part of our multimedia document editor/player, so it'll be supported for quite some time, and I'll even be adding new image formats and such, but since PIL has become available it's become less likely that the image manipulation routines will see significant development, the functionality will probably stay at the current level: fast and simple reading/writing of images and conversion between colorspaces. Sjoerd has converted the various audio file readers and device drivers to a similar architecture as img, so the two may eventually be bundled in a "media toolkit" or some such. -- 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 _______________

Modules
by Rob Managan Oct. 6, 1997

Oct. 6, 1997

In case there is any interest here is the list of modules I have working on the Mac. All of them live in the Extensions folder. img Imaging NumPy These three thanks to Jack for including them PLplot - the plplot graphics module; I have played with the driver for the Mac. scientific_modules - Konrad Hinson's modules. Not throughly tested but appear to work. (no C module; just python code) URNGmodule - LLNL portable random number generator pdbmodule - module to read LLNL's PDB file format. If any of these would help someone let me know nad I will make them available *-*-*-*-*-*-*-*-*-*-**-*-*-*-*-*-*-*-*-*-*- Rob Managan mailto://managan@llnl.gov LLNL ph: 510-423-0903 P.O.

Re: [PYTHONMAC-SIG] import/source dialog
by Jack Jansen Oct. 5, 1997

Oct. 5, 1997

To followup on Steve's mail: If you're running MacOS 8 on a PowerPC there's a contextual menu extension that adds a "copy full pathname to clipboard" to the contextual menu in the finder. I've only been using it for a few days, but I already find it indispensible when doing Python work. I don't remember exactly what the name of the extension is, but I found it at info-mac. -- 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 _______________
