userdefaults3 1.1.8

Python 3 rewrite of userdefaults, a pure-Python interface to NSUserDefaults.

userdefaults3

Python 3 rewrite of userdefaults, a pure-Python interface to NSUserDefaults.

The singular 'UserDefaults' class provides the main interface, which should be used as a regular dictionary. Python types are converted to their Obj-C equivlents on writing to UserDefaults.

Usage

>>> with UserDefaults() as ud:
>>>     ud["key"] = value
>>>

Or, for more flexible access to the UserDefaults class:

>>> ud = UserDefaults()
>>> ud["key"] = value
>>> ...  # other operations here
>>> ud.sync()  # write back to plist file, does nothing on Obj-C backend

On supported platforms that have a Obj-C backend, the UserDefaults class acts as a shim for NSUserDefaults. Otherwise, a naive file handle is used to modify UserDefaults using plistlib.

Supported backends:

• pyobjc (MacOS)
• rubicon-objc (Darwin/Pyto)
• objc_util (Pythonista)

If your platform does not have a Obj-C backend (unless you are on Libterm/a-Shell), you problably should not use this as directly writing to the plist file itself is discouraged (as quoted from Apple's docstring):

Don’t try to access the preferences subsystem directly. Modifying preference property list files may result in loss of changes, delay of reflecting changes, and app crashes.

The naive file method is kept to support platforms which do not have/cannot install a Obj-C backend (i.e Libterm, a-Shell).

Known bugs:

• On Pyto, writing to the inputHistory key using the Obj-C backend results in a SIGKILL (crashes).
