How to get the version of a file

[J Wilson]

Does anyone know how to get the version of an application on OS X (i.e.
the version string that appears in the "Version" field in the "Get Info"
window for an application)?

I'm running OS 10.4.11, python 2.5.

you need appscript "that allows you to control scriptable Mac OS X
applications from Python"
http://pypi.python.org/pypi/appscript/0.18.1

I'm not clear on how to use this to read the version resource.
Specially, I need to get the version of Palm Conduit, which is, I guess,
a "carbonized" shared library... or something.

?

Hello J,

Does anyone know how to get the version of an application on OS X (i.e.
the version string that appears in the "Version" field in the "Get Info"
window for an application)?

I'm running OS 10.4.11, python 2.5.

#!/usr/bin/env python

from xml.etree.cElementTree import iterparse
from os.path import isfile

def get_version(app):
info_file = "/Applications/%s.app/Contents/Info.plist" % app
if not isfile(info_file):
raise KeyError("No version file found")

get = 0
for event, element in iterparse(open(info_file)):
if get:
return element.text

if (element.tag == "key") and (element.text ==
"CFBundleVersion"):
get = 1

raise KeyError("Can't find CFBundleVersion key")

if __name__ == "__main__":
from sys import argv

print get_version(argv[1])

HTH,
