Fluent Assertions Faces Backlash After Abandoning Open Source Licensing
Fluent Assertions is facing backlash after dropping the Apache license for a commercial model, leaving users blindsided and questioning contributor rights.
This is a fork of Marketcircle/bpylist. This one is hopefully more responsive to PRs.
Implementation of the Apple's Binary Plist <https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man5/plist.5.html>
__
and the NSKeyedArchiver format
Binary Plists
For reading and writing plain PLists please use stdlib `plistlib` library.
KeyedArchives
NSKeyedArchiver
is an Apple proprietary serialization format for
Cocoa objects. bpylist2
supports reading and writing
NSKeyedArchiver
compatible archives. The API is similar to the
binary plist API.
Unarchiving an object
.. code:: python
from bpylist2 import archiver
with open('my_archived_object', 'rb') as f:
archiver.unarchive(f.read())
Archiving an object
.. code:: python
from bpylist2 import archiver
my_object = { 'foo':'bar', 'some_array': [1,2,3,4] }
archiver.archive(my_object)
Custom objects ^^^^^^^^^^^^^^
If your 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 and
register it.
The simplest way to define a class is by providing a python dataclass, for example you define a class with all the fields of the archived object:
.. code:: python
@dataclasses.dataclass
class MyClass(DataclassArchiver):
int_field: int = 0
str_field: str = ""
float_field: float = -1.1
list_field: list = dataclasses.field(default_factory=list)
Alternatively you can implement custom unarchiving code.
The Python class needs to implement the encode_archive
and
decode_archive
methods.
.. code:: python
## Define a Python Class
from bpylist2 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)
When the mapper class is defined, register it with unarchiver:
.. code:: python
## Register the class for the Cocoa class 'MyCocoaClass'
archiver.update_class_map({ 'MyCocoaClass': FooArchive })
This package requires the version of plistlib
included in the Python 3.8
standard library. In order to support Python 3.6 and 3.7, a copy of the
Python 3.8 plistlib <https://github.com/python/cpython/blob/e51dd9dad6590bf3a940723fbbaaf4f64a3c9228/Lib/plistlib.py>
__
is bundled with bpylist2
(Specifically, commit 9054967 <https://github.com/python/cpython/commit/90549676e063c2c818cfc14213d3adb7edcc2bd5>
__).
This version will only be used if bpylist2
detects it is running on Python < 3.8.
.. code-block:: bash
$ pip install twine wheel
$ python setup.py sdist bdist_wheel
$ twine upload dist/*
