[Pyobjc-dev] Python rather than ObjC for main?

[Peter M. <zig...@po...>]

Is there any reason why the executable pointed to by CFBundleExecutable 
has to be a Mach-O file?

As a quick test I threw the HelloWorld.py example into a .app Bundle, 
copied and edited a reasonable Info.plist and I now have a double 
clickable version of hello world that still doesn't use any C code.

I just added #!/usr/bin/env python to the top of HelloWorld.py and ran 
chmod +x on it.

Now, I've been experimenting with making a modified Main.py the 
CFBundleExecutable, hoping to avoid the execve(). I can't seem to get 
it working though. NSApplicationMain() dies complaining about not 
finding the Info.plist file. I'm not sure I understand what's 
happening. The launch arguments seem to carry across OK.

Am I reinventing the broken wheel here? Do we have the execve() 
procedure because the simpler approach fails?

Obviously this approach would be inferior to having an embeddable 
version of python in an ObjC wrapper but could this approach be used to 
remove the execve()?

Just a thought,
Peter
