biplist is a binary plist parser/generator for Python.


Binary Property List (plist) files provide a faster and smaller serialization format for property lists on OS X. This is a library for generating binary plists which can be read by OS X, iOS, or other clients.


The API models the plistlib API, and will call through to plistlib when XML serialization or deserialization is required.

To generate plists with UID values, wrap the values with the Uid object. The value must be an int.

To generate plists with NSData/CFData values, wrap the values with the Data object. The value must be a string.

Date values can only be datetime.datetime objects.

The exceptions InvalidPlistException and NotBinaryPlistException may be thrown to indicate that the data cannot be serialized or deserialized as a binary plist.


To install the latest release version:

sudo easy_install biplist


Plist generation example:

from biplist import *
from datetime import datetime
plist = {'aKey':'aValue',
    writePlist(plist, "example.plist")
except (InvalidPlistException, NotBinaryPlistException), e:
    print "Something bad happened:", e

Plist parsing example:

from biplist import *
    plist = readPlist("example.plist")
    print plist
except (InvalidPlistException, NotBinaryPlistException), e:
    print "Not a plist:", e
