I once suggested something like that to Jack (right after my first encounter with the problem ;-) and he didn't sound too thrilled. I'd already be *very* happy if it would raise a more descriptive error, instead of the rather vague: File "DevDev:JustPy:unixfiletest.py", line 1 sys.stdo sys.stdout = s#raw_input("--usb2x, b2y)1y, a2x,lccu b1y = a1y + 2.0*(by- return b1x, b1y magic = calcQmagic(pi/2))/3 midx = radius:xoffset + radius * m b2y = yoffse + xoffsetdy = radius * cos(pi/4) + yoffset y = yost + radius * magic - radiusff print B1x, B1y, Boffset, yoffset, mx, midy, b1x, def b1y = yoffset x = b2xc():agic = ca print "def dra for i in ran x = ra print x, y, "l".5 * pi * (i+1)) / segmentsngle tprint "S"t = sys.stdoutsymain()u dr finally:", "w")e()c()ter-") ^ SyntaxError: invalid syntax Or something. (And it takes forever to print that, since python thinks the whole file is *one* line, and thinks it has to show the line with the Syntax error) Just ================= 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 =================

UNIX files
by Rob Managan Oct. 9, 1996

Oct. 9, 1996

Just to hopefully save someone else difficulty: I learned today that on the Mac Python seems to ignore a script that has UNIX line endings. Unfortunately editors like Alpha read such files easily and you have to look closely to notice that the file uses unix line endings. So check those line endings when working with scripts from a package that are developed on a unix box! *-*-*-*-*-*-*-*-*-*-**-*-*-*-*-*-*-*-*-*-*- Rob Managan mailto://managan@llnl.gov LLNL ph: 510-423-0903 P.O.

plplot module
by Rob Managan Oct. 9, 1996

Oct. 9, 1996

Tom, I downloaded your plmodule and trimodule to look at. In particular I was interested in the plotting interface. The plmodule on your ftp server works with python lists. Has anyone written a version of it that works with array arguments from NumPy? The tutorial for your triangulation code sounded like it worked with NumPy arrays so I thought you might have a version for arrays. Anyone else written such a module? PS. I have the list oriented version working on my Mac, a 7600 and can send it to anyone interested. I hope to clean up the project files and send them off to the plplot archive. *-*-*-*-*-*-*-*-*-*-**-*-*-*-*-*-*-*-*-*-*- Rob Managan mailto://managan@llnl.gov LLNL ph: 510-423-0903 P.O.

I've never tried it, but wouldn't it be good enough to give it type 'appe' and set the 'background only' bit in the finder information?

Python mode on Alpha
by jeffrey P. Shell Oct. 6, 1996

Oct. 6, 1996

Last time i tried Python mode in Alpha 6.5, i couldn't get ANYTHING to work really.. no colorizing or anything else was going on.. I like Alpha, but continue programming in BBEdit 3.5.2 (full). In Alpha i spend too much time trying to figure out Python mode and/or learning TCL and very little time actually programming.. :) But if a good Python mode that works could be passed my way, i think i'll get a clean copy of Alpha start over. This has also given me reason to toy with the notion of making my own Text editor in CodeWarrior (when i get it, hopefully this month) with embedded Python. But Alpha is so good already, i don't think i could make anything that would compare, so it would be more of an experiment in embedding Python. -- .jPS || jeff(a)cynapses.com || http://www.cynapses.com/ry/ ================= 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 and Alpha?
by John Dunning Oct. 4, 1996

Oct. 4, 1996

I was wondering if anyone had created a Python mode for Alpha. If you haven't heard of Alpha, I strongly suggest you check it out at http://www.cs.umd.edu/~keleher/alpha.html. It's a very powerful Mac text editor that is completely customizable using Tcl. It has various modes for C++, HTML, etc., which it uses for syntax coloring and so on. So I wanted to find one for Python. I also wanted to find out if anyone has looked at adding a simple DoScript AppleEvent to the Python shell. You can send an MPW script to ToolSever in a DoScript event and it then returns the shell's response. With this functionality it's possible to create a simple shell inside Alpha that would send scripts to Python and would give you much better editing capabilities while using Python in interactive mode.

PowerPlant?
by gandreas＠skypoint.com Oct. 2, 1996

Oct. 2, 1996

Considering how unappealing the Tkinter stuff is for a mac application, one alternative would be to leverage off an existing framework, namely PowerPlant (the "write your own" is second on the list, but since PowerPlant provides all sorts of goodies that "write your own" doesn't...). It seems that if Python could use the PowerPlant framework (and Constructor), this could be a very big deal for the MacPython communitee. Now, in "a previous life" I spent a great deal of time hacking wxPython, so I got to see, in general, how to fit Python into a class framework, but is the "pass the object as an opaque magic cookie through a procedural (non-object orient) interface" techinque the best thing to do? I was envisioning something more like making a subclass of all "interesting" PP classes that was "scriptendable" - basically there was a python object associated with the object, and then all the method calls would first get passed through the Python layer (assuming the corresponding method call existed in Python land). Yes, creating these subclasses this seems like a lot code, but with the AppleScriptability of CW10, almost all of it could be automated (which was one of the reasons I never considered doing this before). Any other suggestions on strategies on how to best structure the marriage of the C++ and the Python objects? There are obviously other problems to deal with as well (for example, registering the class "read from stream" routines, and who exactly owns the main event loop: the SIOUX console window or PP) but these seem small in comparision... I'm not promising anything here yet mind you, but I know that I would be quite happy and more productive if I could whip up a PP based app as fast as I was able to whip up a Motif app using wxPython...
