Building mxDateTime for Python 2.0
by Vincent Marchetti Sept. 24, 2001

Sept. 24, 2001

I am trying to re-compile the mxDateTime shared library to let me use DateTime in Python 2.0 -- the shared library provided throws exception on import about using the wrong version. I have never compiled any type of shared library before, so girding my loins and firing up CW 5 I set up a shared library project and: 1. included the mxDateTime.c code 2. included stub libraries PythonCore and MSL ShLibRuntime.Lib Result: -- Link failure, could not find function 'floor' I knew this is a standard C function, so I threw the stub MathLib into the pot and cooked. Got a bunch of warnings about duplicate definitions of math functions (in PythonCore and MathLib). Decided to ignore warnings. Successfully made the shared library, successfully imported DateTime into Python 2.0 (actually 2.0b1). However, the test script for mxDateTime failed an assertion. Basically, a function DateTimeFromTicks, which uses the floor function, fails to give predicted results. My question: Am I including the correct library in my project to get the "right" version of floor? Thanks, Vince Marchetti

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. It looks like it hasn't been updated in over 2 years. -- Tony Ingraldi A.M.INGRALDI(a)LaRC.NASA.GOV Phone : (757) 864-3039 Fax : (757) 864-7892

MacPython 2.1a3 also available for classic PPC
by Jack Jansen Feb. 28, 2001

Feb. 28, 2001

Hi gang, things have been moving faster than I had anticipated, and I've put together a fat installer for 2.1a3. The installer, at http://www.cwi.nl/ftp/jack/python/mac/MacPython21a3full.bin will install either classic Python (if you have a non-carbon pre-macos9 machine) carbon Python (if you have a macosx machine) or both (if you have macos 8 or 9 with CarbonLib installed). It also has the MacOSX Configure bug fixed (I hope: I haven't tested it yet, I'll leave that to you folks or do it tomorrow). If you have a machine on which both classic and carbon are installed the installation will be pre-configured for carbon (if all goes well:-). I'd like everyone with some spare time to try this release. Barring any showstoppers we can then go to beta distributions! Oh yes: the installer is a hefty 8MB. I'm going to look into doing an active installer (which only retrieves the bits that are needed). -- 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/ ++++

Cocoa from Jython on MacOSX
by Steven D. Majewski Feb. 28, 2001

Feb. 28, 2001

OK -- I know I was one of several people who suggested that one ought to be able to access macosx Cocoa classes from Jython, however, now that I've actually tried to do it, I can't seem to find those classes anywhere. Importing com.apple.cocoa (or com.apple.cocoa.foundation) doesn't work: Jython 2.0 on java1.2.2 (JIT: null) Type "copyright", "credits" or "license" for more information. >>> import com.apple.cocoa Traceback (innermost last): File "<console>", line 1, in ? ImportError: No module named cocoa >>> import com.apple >>> dir(com.apple) ['__name__', 'buckyball', 'jdirect', 'mrj', 'scripting'] >>> And looking in the jar-files, I can't find it either. I'm guessing this has something to do with cocoa being implemented by the special java<->objective-c bridge. Anybody else got it working? Any clues? -- Steve Majewski

The basics work -- the expected tests failed, some modules were missing, most tests passed. Also, all of my code that I could test (which excludes a lot due to the problems listed below) worked fine. Two problems: - I cannot figure out how to modify the module search path. EditPythonPrefs exists in the Mac:Scripts folder, but fails to run with error: The application "EditPythonPrefs" could not be opened because "PythonCore" could not be found. (I did look at the prefs file with ResEdit and BBEdit, but didn't see anything that looked relevant.) - import Tkinter fails with error: ImportError: No module named Tkinter It is installed -- in Misc:RPM:Tkinter Looking good! -- Russell >Folks, >the next alfa release of MacPython is available.

lambda functions in embedded python
by Etienne Antoniutti Di Muro Feb. 28, 2001

Feb. 28, 2001

Dear list members, I would like to make a call to the "filter" function of the __builtin__ module from a C routine that embeds python. No problems for making the call, but do not know how to define the arguments: Syntax is: filter(function, list) I got the list, It comes out of some Python evaluation, itself; I'd like to use a lambda function for filtering. How do I define the "lambda" in a python C-embedded envirorment?? I need also the filtered list back in my C routine, for further use. Is this worthy instead of rebuilding the list with the PyList_.... set of functions and some if....else... stratement, to filter "manually" the unwanted items?? Any suggestion? thanx in advance 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)

MacPython 2.1a3 available
by Jack Jansen Feb. 28, 2001

Feb. 28, 2001

Folks, the next alfa release of MacPython is available. It is again a Carbon-only release, because of the problems encountered with the previous one. Download it from http://www.cwi.nl/ftp/jack/python/mac/MacPython21a3carbon.bin . MacOS X users should also download a post-last-minute fix: ConfigurePythonCarbon.bin fromthe same directory (see below for details). The most important difference with this release is that it should actually work with CarbonLib 1.0.4 through 1.2.5 and with MacOSX. Various other serious problems, like EasyDialogs and EditPythonPrefs not working have also been fixed. See the release notes for additional fixes. Something that has changed with this release is that ConfigurePython has been replaced by 2 applets: ConfigurePythonCarbon and ConfigurePythonClassic. These will allow MacOS 9 users to switch back and forth between the two runtime models. (Not in this release, because classic-ppc is not included, but in the next). As ConfigurePython{Carbon,Classic} also rebuild the applets for the given execution model the applets are not included in the distribution anymore (except the Configure... ones:-). But: that means that the configure process has become more important, as you'll have no applets if it fails. And, of course, I messed up for MacOSX, so that's why X users should grab the fixed ConfigurePythonCarbon as well, drop it in their Python folder (replacing the broken one) and run it.
