[Pyobjc-dev] NSGraphicsContext.graphicsPort() prints debugging message

[Greg E. <gre...@ca...>]

Every time NSGraphicsContext.graphicsPort() is called, I get
a message like this:

2010-12-16 18:49:28.865 Python[210:607] PyObjCPointer created: at 0x395ded0 of 
type {CGContext=}

Is there any way of turning these messages off? I'm finding
them annoying.

They are printed because creating PyObjCPointers is a bug. The print should go away when you add "import Quartz" somewhere in your program before you call the graphicsPort method (because that way PyObjC knows that it needs to create a CGContext object instead of a generic pointer).

[Pyobjc-dev] Xcode templates?

[Scott H. <sco...@gm...>]

Have the Xcode template changed recently? I'm getting new errors when I try the pyobjc Xcode templates I had installed some time ago.

Xcode ver 3.2.5

I have to remove PPC architectures form the project setting to get it to compile and then I get the console output below.

Any ideas?

Thanks,
-Scott

[Pyobjc-dev] PyObjCTools XCode Support?

[Scott H. <sco...@gm...>]

I'm trying to compile and run the graphlaughs example from big nerd ranch.

http://weblog.bignerdranch.com/?p=19

However, when I build the project they setup.py script fails here:

from PyObjCTools import XcodeSupport

Has this gone away? Why? 

Also, I've noticed that older PyObjC projects tended to follow the pattern of starting up via python and 
now the XCode templates have a main.m that instantiates a python interpreter and loads the .py files.

1. Why did things change?
2. What's the easiest way modify the graph laughs example and get it up and running? Have the changes to PyObjC made its approach
outdated?

Thanks,
-Scott

Re: [Pyobjc-dev] Xcode templates?

[Scott H. <sco...@gm...>]

OK, I found python2.7 in /Library/Frameworks and I got rid of that. Now the Xcode template is working, but it's choosing python2.5.4

How do I control which python the Xcode template picks to run my code? I want it to use the Apple supplied 2.6 version.

Thanks,
-Scott

You cannot control which framework is used by the Xcode templates other than by installing or removing frameworks. The templates should pick whichever framework gets used when you link with '-framework Python'.

This is suboptimal, there really should be an option somewhere that can be used to explicitly select a Python.

I haven't looked at the xcode templates for a long time because working on them is an experience that is not much better than just banging my head against a wall:  the templates are text-ish files (undocumented format) with some markers in them and Apple doesn't provide tools that make it easier to work on templates.

Xcode's code completion and other tools don't work when the project doesn't have an Objective-C file in it.

The link to that example doesn't work for me right now. 

That said, I tend to use py2app to create application bundles and don't use Xcode for Python development at all because for a Python developer Xcode is just a basic editor with a lot of junk (said junk is  very usefull when writing Objective-C, but most tools in Xcode don't understand code that isn't [Objective-]C[++]
