Python 3. OS/X 10.6 Ipython
by John Riordan April 9, 2011

April 9, 2011

I am trying to get IPython running with Python 3.1 on OS/X 10.6.3. The install script for IPython configures it to run with Python 2.6. Is there a way around this?

C++ ABI 1002/102 incompatibility with wxPython
by Brendan Simon (eTRIX) March 1, 2011

March 1, 2011

I have a wxPython app that is built with py2app. A user recently reported the following error when trying to run the app. Fatal Error: Mismatch between the program and library build versions detected. The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx containers,compatible with 2.6), and your program used 2.8 (no debug,Unicode,compiler with C++ ABI 102,wx containers,compatible with 2.6). Abort trap logout It appears to be a difference in the wx libraries on the target system and the wx libraries on the build system. Unfortunately, at this stage, I do not know what the OS X version is on the target system. The app was built using Python 2.5.4, (wxPython 2.8.11.0 or 2.8.4.2 ??) on OS X 10.6.6. Is there anyway to fix this with a py2app setting ?? Doesn't py2app copy all the libraries to the app bundle ?? I guess that doesn't guarantee that the libraries will load on any OS. What about path settings ?? I presume others have solved this before. Any suggestions ?? Many thanks, Brendan.

Apple's "scripting bridge" push, You mean BridgeSupport (http://bridgesupport.macosforge.org/), which provides XML descriptions of the non-introspectable bits of Cocoa APIs for easy consumption by PyObjC, MacRuby, etc. > its claim of full Cocoa support for Python, Ruby, etc. seems hard to believe now. I would suggest dropping a note to Laurent Sansonetti (BridgeSupport + MacRuby lead) and other bridge & runtime devs (http://www.cocoadev.com/index.pl?CocoaBridges) (http://www.cocoadev.com/index.pl?CocoaLanguages) to find out if they're also affected. Laurent may also be in a marginally better position to agitate, seeing as he's an Apple employee. (http://www.macruby.org/) > What other options are there? Specify your GUI by hand? Is it just the Read/Write Class Files functionality that's affected, or has Xcode 4 also lost the ability to specify IB classes manually? (IB 2 was good at this; IB 3 not so good but I think it was still possible.) HTH has

appscript module - creating k. type objects
by Benjamin Golder Feb. 27, 2011

Feb. 27, 2011

Hello, I'm learning and enjoying the appscript module, but I'm a little confused about how to instantiate basic k. type objects. for example, if I want to create a variable that holds a k.boolean value to use while scripting an application, how do I create it, and then pass it to the set() method of a property within that application? let's say I'm scripting Adobe Illustrator: il = app('Adobe Illustrator') doc = il.current_document.get() layers = doc.layers.get() layer = layers[1] in Illustrator, a layer object has a property layer.visible, which has a k.boolean value. how do I create a variable m which is a k.boolean type, such that: layer.visible.set(m) will set the .visible property to a different k.boolean value? m = k.boolean(True) doesn't work m = make(new k.boolean) doesn't work there must be a simple answer, but I don't know it. Any and all help or advice is appreciated, thanks!! -Ben

Don't install Xcode 4 when you use PyObjC for your GUIs and want to use Interface Builder. The Interface Builder that's included with Xcode 4 no longer supports Python. I've filed a bug in Apple's tracker, but I have no idea if that will have any effect at all. It'll probably not help a lot, I filed the same bug just after WWDC last year and that didn't help either.

On OS X installs, bin/python and > bin/pythonw are supposed to be identical. Indeed you are right. The python and pythonw varieties are identical for Python 2.7 and my wxPython application works fine with either. I tried again with my Python 2.5.4 install and that does have the problem. "pythonw myapp.py" works fine. "python myapp.py" fails with the following error. Traceback (most recent call last): File "myapp.py", line 18, in <module> import main as myMain File "/Users/brendan/src/main.py", line 19, in <module> from theapp import MyApp File "/Users/brendan/src/theapp.py", line 20, in <module> import wxAnyThread ImportError: No module named wxAnyThread It looks like it is just a path issue. So it should be easy to solve, but there is a difference in behaviour between python and pythonw with Python 2.5.4, even though the binaries are identical. I presume that the the interpreter looks at the command that it is invoked with and does something different with sys.path ?? Cheers, Brendan.

py2app and module finding
by Prashant Saxena Feb. 22, 2011

Feb. 22, 2011

Hi, It's related to my previous post regarding .app bundle size produce by py2app. When I looked inside the .app bundle, It gives me some confusion: 1. I have a custom package name "core". There is directory structure inside filled with scripts. Some of the scripts are compiled using cython. This give you three version of single script (.py, .pyc and .so). py2app is copying .so to .lib folder inside bundle as well as it's also copying .py and .pyc inside "site-package/core". Why it's like that? 2. Not only python scripts but every thing under the folder is going inside the .app. It seems py2app is globing all the files instead of required modules/scripts. I am using a very simple setup.py. It's almost the same as examples/wxpython/2.5/superdoodle Prashant
