bpylist 0.1.4

parse and generate binary plists and NSKeyedArchiver archives

Implementation of the Apple’s Binary Plist and the NSKeyedArchiver format

Usage

Binary Plists

Generating bplist is easy, and similar to the plistlib module in Python’s Standard Library

from bpylist import bplist

bpylist.generate(my_object)

Reading is easy as well. The generate function takes a bytes object and returns the top-level object of the binary plist.

from bpylist import bplist

with open('myplist.plist', 'rb') as f:
    bpylist.parse(f.read())

KeyedArchives

NSKeyedArchiver is an Apple proprietary serialization format for Cocoa objects. bpylist supports reading and writing NSKeyedArchiver compatible archives. The API is similar to the binary plist API.

Unarchiving an object

from bpylist import archiver

with open('my_archived_object', 'rb') as f:
    archiver.unarchive(f.read())

Archiving an object

from bpylist import archiver

my_object = { 'foo':'bar', 'some_array': [1,2,3,4] }
archiver.archive(my_object)

Custom objects

If you archive includes classes that are not “standard” Cocoa classes (NSString, NSNumber, NSDate, NSNull, NSDictionary or NSArray), you register a Python class that the Cocoa class maps to. The Python class needs to implement the encode_archive and decode_archive methods.

## Define a Python Class

from bpylist import archiver

class MyClass:
    first_property = None
    second_property = None

    def __init__(self, first_property, second_property):
        self.first_property = first_property
        self.second_property = second_property

    def encode_archive(self, archive):
        archive.encode('first_property', self.first_property)
        archive.encode('second_property', self.second_property)

    def decode_archive(archive):
        first = archive.decode('first_property')
        second = archive.decode('second_property')
        return MyClass(first, second)

## Register the class for the Cocoa class 'MyCocoaClass'

archiver.update_class_map({ 'MyCocoaClass': FooArchive })
