Python tools to manipulate JARs ?
I run build processes for a Java shop using Python (and some Ant). Would anyone care to suggest favoured tools for manipulating the innards of JARs? Or do I just treat them as plain zipfiles and get stuck right in there? Mainly I'm trying to query lists of classes and their embedded versions and do some library dependency reporting. Performance speed is starting to be an issue, as there's 1500+ classes in this bucket and it's an interactive query. Thanks for any suggestions -- http://mail.python.org/mailman/listinfo/python-list

I have not tried this, but... Assuming jython is out of the question You might want to try a simple java command line program you could run from popen -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Andy Dingley Sent: Wednesday, January 31, 2007 11:11 AM To: python-list@python.org Subject: Python tools to manipulate JARs ?

To print out the classes you can use zipfile
it will list the contents of a jar file also
import zipfile
zf = zipfile.ZipFile("some.jar")
for info in zf.infolist():
print info.filename
Or print to a file
import zipfile
zf = zipfile.ZipFile("some.jar")
for info in zf.infolist():
classes = info.filename
myfile = file("classes.txt", 'w')
print >> myfile, classes
Enjoy
