For reasons unknown to me this message bounced to the -request address (maybe because the subject starts with "HELP"?), so I'm forwarding it. ------- Forwarded Message To: pythonmac-sig(a)python.org From: subra(a)apple.com (Subra Mayilvahanan) Subject: HELP: extension module Hi I need some help with the python extension modules (Version 1.3). I want to create my own extension module as a shared library on a powermac. Here is what I did: * Wrote a tiny module with just one function (source is included at the end.) Source file name: "myfirstmodule.c", shared lib name: "myfirstmodule". * Copied the CW7 PythonCore project file, removed the sources from that and added my module source file (retained the run-time and shared lib glue stuff). * Built the shared lib successfully and copied it to the system extension folder. * Typed "import myfirstmodule" in "PythonPPC" std window. I am getting an error saying "no module named myfirstmodule".

I figured out why I wasn't able to import my module. Its that ".slb" thing I missed in the filename! --subra ================= 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 =================

Printing from Python?
by guzdial＠cc.gatech.edu March 1, 1996

March 1, 1996

Does anyone print anything directly from Python? I was trying to figure out how to do it and can't seem to find anything built-in to Python or in the Mac-specific extensions. (There was echo2printer, but that seems to have gone away?) I'd love to be able to dump text and/or postscript. Thanks!

Problems with new TkInter on Mac
by guzdial＠cc.gatech.edu Feb. 26, 1996

Feb. 26, 1996

I'm trying to use the Beta 2 release of PythonTk with the new Tkinter. It hung my machine several times, and after playing with mixtures of Beta 1 and Beta 2, I'm pretty sure it's the new Tkinter.py. (Guido, I did make sure that my line-endings are Mac-ified -- BBedit reports that it's a Mac-style text file.) I can run the old Tkinter with either Beta 1 and Beta 2, and all is fine. But whenever I use the new Tkinter, my cursor just freezes very early in the startup. (System 7.5 on a Quadra 840AV with 16M RAM.) I cleaned out a whole bunch of Inits, thinking that maybe that was the problem, but I'm still getting freezes. Any suggestions? Did the tkconstants.py file change, too? BTW, in case anybody else is playing with the Tkinter examples, canvas-with-scrollbars has two options, 'xscroll' and 'yscroll', which need to be changed to the documented 'xscrollcommand' and 'yscrollcommand' to get them to work right. Then everything works fine. (I'm working my way through the Ousterhout book and finding that the marriage of Tk and Python is really terrific!)

Re: [PYTHONMAC-SIG] Tk Python with Tcl/Tk beta 2
by Jack Jansen Feb. 25, 1996

Feb. 25, 1996

If people are desparate for a PPC-version of TkPython I can probably make one available in the next few days (I built one from Guido's sources with the beta-1 desitribution with few problems, so I think beta-2 should be easy too), but I'll only do it if people can't wait for it. It'll be a single (huge) executable, like the 68k version. What I would really like to concentrate on is a PPC Python that uses the normal shared-library structure but based on the GUSI I/O system, and with tkinter/tk/tcl in a dynamic module (so it doesn't take oodles of memory if you don't use it), but this'll probably take a week (or maybe two), so I'd prefer people to wait a while and use 68k tkpython in the mean time. -- 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 =================

Tk Python with Tcl/Tk beta 2
by Guido van Rossum Feb. 25, 1996

Feb. 25, 1996

Following the new Tcl/Tk beta release, I've made a new version of Python with Tk available (still only for 68K Mac, though I have now confirmed that it can be done for PPC as well). The URL of the directory is ftp://ftp.python.org/pub/python/mac/beta/ Get the files README-tk, python68Kgusitk.sit.hqx and Tkinter.py (plus the Python 1.3.1 release in the same directory if you haven't got it yet). For build instructions, see README-tk-build and fetch some additional files. The changes to _tkinter.c are incompatible with the Tcl/Tk beta 1 (the only other changes were made to Tkinter.py and the project; you may want to get the new macmodule.c since there were some silent updates to it after I first announced the previous version). The only noticeable change is the fact that the SIOUX console window now gets its events correctly. It is now also possible to interrupt the Python code using Command-Period. The bus error in CharWidth seems to have gone, and I have successfully run several applications. Grail sometimes works ;-) --Guido van Rossum <guido(a)CNRI.Reston.VA.US> URL: <http://www.python.org/~guido/> ================= 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.h and freeze.py

Although this is not the appropiate list, I thought some of you might be able to steer me in the right direction. I want to write a C extension module on NT but I cannot find Python.h in the NT distribution. The same goes for freeze.py.

PYTH creator code
by Jack Jansen Feb. 20, 1996

Feb. 20, 1996

Folks, apparently the 'PYTH' creator code that has been used by python for a long time is officially in use by someone else, so for the next release I'll have to pick a different one (probably 'Pyth'). I'll include a script with the next distribution to fix existing files, but I'm posting this message to see if anyone has any ideas of other things that have to be changed, or other problems this may cause. Guido: shall I register the codes in the name of the Python Software Activity? If so: what is the address of the PSA? -- 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 =================

Re: [PYTHONMAC-SIG] Mac Python with Tk -- early beta
by guzdial＠cc.gatech.edu Feb. 19, 1996

HOORAY!!! After I fixed my line endings and got Tkconstants.py from Guido, it all worked! It's pretty amazingly fast (being used to HyperCard and SuperCard). Quitting is a little weird, in that you quit from Tk and then again from Python. (And if you just keep importing demos, everything gets added into the one window, which is also strange.) But it works and I'm really excited about using this!! A couple of odd things: - Not all the tkinter demos work. For example, the scrolling canvas gives me some error about "xscroll." But most of those I've tried work just fine, which is pretty amazing compatibility. - Try pong and set the speed to really low. The ball actually "cleans" the screen -- it's trail is a different gray shade from the background. >> I typed in the "Simple Hello World Program" from the "Tkinter Life >> Preserver" documentation, and I'm getting strange errors: >> - If I just import it, I get told that Frame is unknown. >> - If I execfile it, I get an I/O error. >> (See below) >> >> I start WISH before I do any imports -- is that the right thing to do? > >You shouldn't have to run WISH at all -- the Tk library and Tcl >interpreter are linked into the Python application. > >Did you transfer the Tkinter.py file that was also on the ftp site? >If not, please do so.

I'm very excited about this announcement, and just downloaded all the different pieces. But I can't seem to get any of it working. I typed in the "Simple Hello World Program" from the "Tkinter Life Preserver" documentation, and I'm getting strange errors: - If I just import it, I get told that Frame is unknown. - If I execfile it, I get an I/O error. (See below) I start WISH before I do any imports -- is that the right thing to do? Thanks for any pointers!
