Using py2app on 10.5 to build apps that run on 10.4?
by Russell E. Owen Feb. 23, 2008

Feb. 23, 2008

I'd love to upgrade to Leopard, but I maintain a python application that needs to run on 10.4 (and preferably 10.3.9). So...is it now practical to build 10.4-compatible applications using py2app on a 10.5 computer? What is involved? (For instance I remember reading that the built-in python needed some fixes for distutils to be able to make fat binaries, but I have no idea what the fixes are or how to install them). Does it help (or hurt?) if I use a 3rd party installation of Python, instead of the built in python? -- Russell

Creating binary packages on OSX
by Matthias Baas Feb. 22, 2008

Feb. 22, 2008

Hi, I have a question about distributing binary package on OSX (I'm still rather new to OSX but now that I have a Mac I'd like to provide an OSX binary of an Open Source package of mine). I was using the bdist_mpkg distutils extension to create a binary and could turn that into a *.dmg. Testing this installer on my own machine works fine. So generating the binary is no problem at all (thanks to all who contributed to this distutils extension! Great work! I hope this will make it into the official Python build eventually) My question is rather about the requirements of the generated installer, i.e. who can use it to install the package? Does the installer only work with MacPython or will it work with any version of Python (provided that the version number matches, of course)? Does the installer just copy the files into a predefined directory that must be the same on all machines or is it like the Windows installer and it figures out itself where Python is installed and puts the files into the correct location? I'm creating the binary on Tiger. Will the binary work on Leopard as well or does this require a recompile? Is there anything else that needs to be considered to get a "true" OSX binary package? (I made sure everything was compiled as a universal binary, but that's about it) I'm grateful for any infos on how to properly create a binary package on OSX. Cheers, - Matthias -

uninstalling macpython
by Stephen Uhlhorn Feb. 22, 2008

Feb. 22, 2008

Hello- How do I uninstall MacPython cleanly from my leopard system? I'd like to revert to the system python without reinstalling the entire OS. Do I just zap /Library/Frameworks/Python.Framework and fix my PATH? Or, are there other considerations? Thanks- -stephen

py2app error with pygraphviz module

CoreGraphics, 10.5
by Erik van Blokland Feb. 18, 2008

Feb. 18, 2008

Folks, I've been wrestling with some CoreGraphics stuff, OSX 10.5.2, stock Python 2.5.1. I want to load a RGB image, then load a grayscale image, draw one while using the other as a mask. I can build all the required objects. I can draw with "masking-like things" happening to the image. But the masking appears to be according to a (random) piece of memory, rather than the pixels from the mask image. The RGB image: http://erik.letterror.com/cg/picture.png The grayscale mask: http://erik.letterror.com/cg/mask.tif The resulting image: http://erik.letterror.com/cg/results.png The script: http://erik.letterror.com/cg/cgMaskTestPost.py The script which draws this file is below. Yellow background, rgb image of a neon sign, mask. I get the impression I'm somehow not making the right kind of mask. Or perhaps the parameters I'm passing to it are wrong. Perhaps the mask image is wrong. I've tried black/ white bitmaps, tiff, jpeg, png, grayscale 8 bit, 24 bit. Different formats result in different patterns being used as a mask - so there is some correlation between the file and the result. Is this anywhere close to how it needs to be done? Any pointers are most welcome, thanks! Erik van Blokland #! /usr/bin/python2.5 from CoreGraphics import * import os def test(): testWidth = 1000 testHeight = 500 fileName = 'picture.png' # name of a 8 bit PNG, RGB image maskName = 'mask.tif' # name of an 8 bit, grayscale tiff # the paths root = os.getcwd() filePath = os.path.join(root,fileName) maskPath = os.path.join(root,maskName) dstPath = os.path.join(root, "results.png") # data providers for the image and the mask img = CGImageImport(CGDataProviderCreateWithFilename(filePath)) maskProvider = CGDataProviderCreateWithFilename(maskPath) imgMask = CGImageImport(maskProvider) # first, let's find out some things about the mask. width = imgMask.getWidth() height = imgMask.getHeight() bitsPerComponent = imgMask.getBitsPerComponent() bitsPerPixel = imgMask.getBitsPerPixel() bytesPerRow = imgMask.getBytesPerRow() shouldInterpolate = True decode = [0,255] # not relevant? # make the mask maskObject = CGImageMaskCreate(width, height, bitsPerComponent, bitsPerPixel, bytesPerRow, maskProvider, decode, shouldInterpolate) # now make the image with source image AND mask imgWithMask = CGImage_createWithMask(img, maskObject) # make a new image to save it all ctx = CGBitmapContextCreateWithColor(testWidth, testHeight, CGColorSpaceCreateDeviceRGB(), (0,0,0,0)) # a background color ctx.setRGBFillColor(.9, .9, 0, .8) ctx.addRect(CGRectMake(0, 0, testWidth, testHeight)) ctx.fillPath() # draw the masked image ctx.drawImage(CGRectMake(50, 50, width, height), imgWithMask) CGContext_writeToFile(ctx, dstPath, kCGImageFormatPNG) print "done" if __name__ == "__main__": test()

How to print unicode to OS-X Terminal.app
by Christopher Barker Feb. 15, 2008

Feb. 15, 2008

Hi all, I generally use Terminal.app as my terminal with python. With all the default settings, it appears to be a showing up as an ascii terminal to python. This means that if I do: print UnicodeObject it tried to encode it as ascii, which often fails. However, it seems that OS-X is pretty unicode savy, so you'd think I should be able to do this. Indeed, if I go to setting, I see that under display, it's set to UTF-8. So how to I get Python to convert to utf-8 with a print statement, instead of ascii? thanks, -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

py-appscript 0.19.0 preview
by has Feb. 11, 2008

Feb. 11, 2008

Hi all, If anyone's interested in checking out the next version of py- appscript, revision 461 moves the py-appscript-0.19.0 branch to the main trunk: svn checkout http://appscript.svn.sourceforge.net/svnroot/appscript/trunk py-appscript-0.19.0 Much clearing out of accumulated baggage has occurred since 0.18.x, bringing py-appscript more or less into line with rb-appscript. I've still to check that 64-bit support actually works (advice on how to build 4-way fat extensions on Leopard's Apple-installed Python would be appreciated), and there's a few other things still to do, but once all that's sorted I'm thinking of declaring it beta at long last. Comments, suggestions, offers of help, etc. welcome as always. Cheers, has -- http://appscript.sourceforge.net http://rb-appscript.rubyforge.org

Having trouble building Python w/ Tcl/Tk on my new Macbook Pro
by skip＠pobox.com Feb. 10, 2008

Feb. 10, 2008

I finally put my PowerBook G4 out to pasture and bought a MacBook Pro. I used SetupAssistant to transfer data from the old box to the new one. I'm having trouble building any version of _tkinter (from svn 2.5, trunk (2.6) or py3k) on my new box. Today I decided to debug the problem a bit. I'm getting this warning when linking _tkinter.so: ld: warning in /Library/Frameworks//Tcl.framework/Tcl, file is not of required architecture ld: warning in /Library/Frameworks//Tk.framework/Tk, file is not of required architecture which suggests to me that those versions of Tcl and Tk are probably PPC only. (I suspect old AquaTk frameworks copied over by SetupAssistant.) Looking in /Library/Frameworks I see drwxr-xr-x 6 root admin 204 Apr 29 2007 AquaTerm.framework drwxr-xr-x 6 root staff 204 Jan 26 2005 CamelBones.framework drwxrwxr-x 5 root admin 170 Aug 4 2007 FxPlug.framework drwxr-xr-x 10 root admin 340 Aug 15 2005 GMP.framework drwxrwxr-x 8 root admin 272 Jan 31 00:40 HPDeviceModel.framework drwxrwxr-x 6 root admin 204 Jan 31 00:40 HPPml.framework drwxrwxr-x 7 root admin 238 Jan 31 00:40 HPServicesInterface.framework drwxrwxr-x 7 root admin 238 Jan 31 00:40 HPSmartPrint.framework drwxrwxrwx 6 skip staff 204 Feb 8 2005 HaskellSupport.framework drwxr-xr-x 9 ellen wheel 306 Sep 6 2006 Mono.framework drwxrwxr-x 5 root admin 170 Aug 4 2007 PluginManager.framework drwxrwxr-x 4 root staff 136 Jun 20 2003 PrintMeSSL.framework drwxrwxr-x 5 root admin 170 Aug 4 2007 ProFX.framework drwxrwxr-x 7 skip admin 238 Apr 18 2007 Python.framework drwxrwxr-x 6 root admin 204 Jan 31 2005 SASL2.framework drwx------ 5 skip admin 170 May 2 2004 SDL.framework drwxrwxr-x@ 6 root admin 204 Sep 26 2005 StuffIt.framework drwxrwxr-x@ 5 root admin 170 Sep 26 2005 StuffItSupport.framework drwxr-xr-x 11 root admin 374 May 14 2004 Tcl.framework dr-xr-xr-x 11 root staff 374 May 14 2004 Tk.framework drwxrwxr-x@ 6 root admin 204 Jan 24 2002 XPrint2ModemCtrAPI.framework There are a number of frameworks there which look suspiciously old. How can I tell which are PPC and which are Intel? Is it okay to just remove the Tcl & Tk frameworks? (Renaming them caused the link to succeed.) I noticed much more recent versions in /System/Library/Frameworks. Thanks, Skip

module metrics and Framework comparisons
by DavidW Feb. 7, 2008

Feb. 7, 2008

Hi All, Does anyone know of a set of (formalized software engineering) metrics against which (python) modules can be evaluated? I am about to (yet again) summarise several modules which do similar things and I wondered if anyone knows of a such a set. I'd like to be able to include things like level of support, code readability, documentation. I guess you all know the rap. Also, I've been background reading around Application Frameworks and wondered if anyone's got a good/favourite reference which compares Python with others. Couldn't find anything on python.org. thanks a million, David ________________________________________________ David Worrall - Experimental Polymedia: www.avatar.com.au - Education for Financial Independence: www.mindthemarkets.com.au Australian research affiliations: - Capital Markets Cooperative Research Centre: www.cmcrc.com - Sonic Communications Research Group: creative.canberra.edu.au/scrg
