Your application needs python preferences resources (a "Popt" and a "GU<sigma> I" resource). The easiest way to get these is dropping your application on EditPythonPrefs. An alternative (often handier because you don't have to do it after every build) is to create a resource file that includes the Popt and GUSI resource and include this in your build. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

The module is available at http://monsoon.harvard.edu/~mhagger/Gnuplot/Gnuplot.html. The latest version includes support for the Mac. Also, the Mac gnuplot distribution contains a simple console written in python. You can obtain the Mac port of gnuplot at http://users.ece.gatech.edu/~schooley/gnuplot.html.

State of BBPy? More general Tkinter development question.
by Russell E Owen Oct. 17, 2000

Oct. 17, 2000

I have gotten BBPy to work with Pyton 1.6a2 (but not 1.5.2) by changing "from Types.py import *" to "from types.py import *" (i.e. types must be lower case) in PythonSlave.py. One simple script I tried ran fine. However, when I tried to run a Tkinter script I'm working on Python hung and so did BBEdit. (In general BBEdit seems susceptible to hanging if Python hangs when using BBPy). Is this a known limitation in BBPy, that it fails with Tkinter scripts? Or did I just get unlucky and have something fail, or what? Any suggestions for a good environment in which to build Tkinter applications would be very much appreciated. It doesn't have to be on the Mac. The present business of editing the file, dropping it onto PythonInterpreter, having it choke, analyzing the output and doing it all over again is pretty painful. Also, any suggestions on ways to interact with a Tkinter script while building it would be appreciated. I'd like to start things up and then be able to talk to my widgets and generally exercise my code interactively. Regards, -- Russell

C++ extensions, exceptions?
by David Andersen Aug. 31, 2000

Aug. 31, 2000

The following very simple C++ Python extension fails on the Mac if the line "test();" is included. (Metrowerks C/C++ 5.3). It appears that exception handling is simply broken. I can't find anything wrong with the code or the project settings. Has anyone written an extension to Pythonmac in C++ ? #include "python.h" void test() { try { throw 3; } catch( ... ) { } } extern "C" PyObject *dmaxtnd(PyObject *self,PyObject *args) { int xx,yy,cc; if (!PyArg_ParseTuple(args,"ii",&xx,&yy)) return(NULL); cc = xx+yy; test(); return(Py_BuildValue("i",cc)); } /* dmaxtnd */ /* method table */ static PyMethodDef dmamethods[] = { {"dmaxtnd",dmaxtnd,METH_VARARGS}, {NULL,NULL} }; extern "C" void __declspec(dllexport) initdmaxtnd() { Py_InitModule("dmaxtnd",dmamethods); }

Etienne, have a look at BuildApplication. It won't do what you want out-of-the-box, because you need to extend a C++ application, but you can probably hack it a little so that it takes your application as the main (C) application in stead of PythonInterpreter, as it normally does. Then you'll end up with a single binary that has everything you need included. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Distributing Python Applications
by Etienne Antoniutti Di Muro Aug. 31, 2000

Aug. 31, 2000

List members, hello there! :-) I'm interested in shipping an application. MyApp usese two technologies: Python and C++. I've built some modules (MyMods.py) for the Python side of MyApp, that work along with the standard python modules. MyApp C++ side uses those modules quite like a shared library (intensive use of embedding/extending python), having PythonCore linked to the code and initializing the Python interpreter at startup. Well the *BIG* deal is: I would like to ship MyApp to an average Mac User, hiding the python technology throughout the whole use of MyApp. This mostly deals with: installation of PythonCore & base Python Modules & managing PythonPrefs. My Idea is: 1- Python is alredy present on the Mac that will host MyApp (do I detect this just reading "Python Preferences", if any, in the System Folder??): no problem, I will add the path to MyMods.py to python prefs. 2- Python is not present on MyApp User Mac:I need to install PythonCore+basic Modules+MyMods.py +write python preferences. step 1: MyApp Installer will copy python essentials onto the User HD, step 2: How does MyApp Installer set up Python Preferences (using whether C++ or Python), before PythonCore is properly initialized in its new location? question: Should I compile any of python essential modules (= generate '.pyc' files) for the specific Mac, before the first run?? step "user friendly": Into the Macintosh Word a user feels free to move around his HD folders and application, keeping them working in any location. This implies a big work "behind the scenes" to keep track of paths in all that moving. How to let MyApp do this for me and MyApp User?? I've always in mind my first sperimentation with python: after every move of PYTHON HOME, nothing worked until PythonPrefs were correctly updated . How to avoid this boring chore? That's it!! Any suggestion ??? thanx etienne -- it's time to leave this town it's time to steal away let's go get lost anywhere in the U.S.A. (RHCP)

Embedding Python w/o SIOUX popping up
by Jared Updike Aug. 31, 2000

Aug. 31, 2000

I am embedding Python in a Code Resource that loads as an extension to the program Igor. My extension loads the PythonCore Shared Library. When I call my command from the Igor command window and the code in my extension calls PyMac_Initialize() a SIOX window pops up and another apple menu is added at the top of the screen. There is porbably some way to use the funcitonality of PythonCode without loading the Window/menubar, and if there is, I would love any advice anyone may have on this situation.

Doctor, Doctor, It hurts when I do this
by Magladry, Stephen Aug. 30, 2000

Aug. 30, 2000

I just started using Python a few days ago and came across something you don't want to do. I was building an extension. Being it was my first, I started out with the starter project posted in April by Louis Pecora (BTW, thanks). For one reason or other, it wasn't working. I can't remember quite what was wrong, but something was. So, I started fiddling with stuff to see if I could get things to work. One thing I did was to merge the PythonCorePPC lib with my extension. This leads to the title of the e-mail and the answer is, "DON"T DO THAT!" I finally got the test extension functioning, but after seeing that everything was working and quitting the interpreter or the IDE, I was unable to start up anything associated with Python. No IDE, no interpreter, no EditPythonPrefs, no ConfigurePhython, even after a restart. The only workaround I found was to trash the Python prefs folder and reinstall Python. Something had to be wrong. So I started to unroll the changes that I had done. Low and behold, when I unrolled the merging of the PythonCorePPC lib, I could quit and restart the IDE without a problem. So the moral of the story is, "DO NOT merge the PythonCorePPC lib in with your extension. You will hate yourself for it."

Pythondoc on the Mac
by Paul-Michael Agapow Aug. 29, 2000

Aug. 29, 2000

Has anyone got Pythondoc working on a Macintosh? So far, it's defeated my admittedly superficial Python knowledge (I'm not even sure how you run a package on the interpreter) and it sure would be nice to have a decent documenting tool ... p-m -- Paul-Michael Agapow (p.agapow(a)ic.ac.uk), Dept.
