[Pyobjc-dev] py2app glory

[Diez B. R. <de...@we...>]

Hi,

after posting here a few weeks ago & finding that py2app didn't work 
with XCode-generated PyObjc-projects anymore, I dug deeper and finally 
found a solution. No need to use xcode, no need to use some compiled 
code, and the ability to develop using an aliased bundle, which makes 
turn-around much faster.

Also, you can use a python of your choice, not only the os x 
pre-installed one.

This is what you need to do to develop using py2app:

  - create a python-cocoa-project using xcode
  - rename the main.py to MyProject.py
  - place a setup.py in the project-root that looks like this:


---------
"""
Usage:
     python setup.py py2app

Append -A to
"""
from setuptools import setup

import subprocess
import os


plist = dict(
     CFBundleDocumentTypes=[ # this you need if you have a 
document-based  app
         {
             "CFBundleTypeExtensions" :["????"],
             "CFBundleTypeIconFile" : "",
             "CFBundleTypeName" : "DocumentType",
             "CFBundleTypeOSTypes" :	["????"],
             "CFBundleTypeRole" : "Editor",
             "NSDocumentClass" : "CameraCalibratorDocument",
             }
	]
)

for base, dirnames, filenames in os.walk(os.getcwd()):
     for filename in filenames:
         name, ext = os.path.splitext(filename)
         if ext == ".xib":
             inf = os.path.join(base, filename)
             outf = os.path.join(base, "%s.nib" % name)
             cmd = ["ibtool", "--errors", "--warnings", "--notices", 
"--output-format", "human-readable-text", "--compile", outf, inf]
             if subprocess.call(cmd):
                 raise Exception("ibtool puked.")

setup(
     data_files=['English.lproj'],
     app=[
         dict(script="MyProject.py", plist=plist),
     ],
     install_requires=["pyobjc"],
     setup_requires=["py2app"],
)
---------

That's it.

Please be aware that due to the new XIBs & the need to compile them 
using ibtool, the changes to them aren't applied immediatly - you need 
to re-run the py2app-command. But that's pretty cheap.

Maybe this helps others,
