Project description
Description
Pickled Data Object (pkldo) is method #470 for saving Python data to a file. It provides functionality for create, retrieve, update, and delete operations and uses Python’s built-in Pickle routines. It also performs operations atomically and offers file integrity. Its best fit is for applications with basic data persistence needs.
Development Status
Tested on BSD and Linux.
Windows compatibility will be next.
Documentation in progress.
Quick Example
Here’s a brief example of how to use a Pickled Data Object:
>>> import pkldo >>> class Test(pkldo.Pdo): ... pass ... >>> a = Test() >>> a.some_data = "howdy" >>> a.create_pdo('/tmp/some_file') >>> b = Test() >>> b.load_pdo('/tmp/some_file') >>> b.some_data 'howdy' >>> b.some_data = "hmmmm" >>> b.save_pdo() >>> c = Test() >>> c.load_pdo('/tmp/some_file') >>> c.some_data 'hmmmm' >>> c.delete_pdo() >>>
