• test_files/vcard40_simple.vcf - Basic vCard 4.0 test file
• test_files/vcard40_full.vcf - Full vCard 4.0 with all properties
• test_files/vcard40_group.vcf - vCard 4.0 with KIND=group and MEMBER
• test_files/vcard40_org.vcf - vCard 4.0 for organization
• test_files/vcard40_location.vcf - vCard 4.0 for location
• test_files/vcard40_multilang.vcf - Multilingual vCard 4.0 with ALTID

Modified Files:

• vobject/init.py - Added version parameter to vCard(version='3.0')
• tests.py - Updated behavior registry test for new behaviors

New vCard 4.0 Properties Implemented

• KIND - individual/group/org/location
• GENDER - sex and gender identity
• ANNIVERSARY - marriage date
• LANG - language preferences with PREF
• IMPP - instant messaging URIs
• RELATED - relationships with TYPE
• MEMBER - group members (only for KIND=group)
• CLIENTPIDMAP - sync mapping
• XML - extended XML data
• SOURCE - vCard source URI

Usage:

import vobject

v3 = vobject.vCard()

v4 = vobject.vCard('4.0')
v4.add('fn').value = 'John Doe'
v4.add('kind').value = 'individual'
v4.add('gender').value = 'M'

parsed = vobject.readOne(vcard_string)  # Works for both 3.0 and 4.0

Note that Radicale has merged in support for these changes in Kozea/Radicale#1948, with the hope that they will arrive in a 1.0.0 release.

Thanks @jwiegley

@jwiegley, I don't think we need the first three commits here (the CNAME ones)?

Also, would you be able to convert the test cases to use pytest, like the other tests in the master branch?

[jwiegley]

I saw those changes from the other repository, but didn't realize they had carried through to my PR. I'll remove them.

@da4089 I've changed over the tests, please confirm it's in the format you expect now.
