Overview

Shared is a Python package created to be the programmer's companion when it comes to storing unstructured application data, managing configuration files, caching data, and exchanging data with other programs.

Under the hood, Shared uses Paradict to encode a dictionary populated with strings, scalars (integer, float, decimal float, complex, booleans), date and time, null value, binary data and nested collections (list, set, and dictionary).

Note: This library isn't intended to replace a proper relational database such as SQLite !

Example

from shared import Dossier, HOME
from datetime import datetime
from pathlib import Path

# load a picture
with open("/home/alex/image.png", "rb") as file:
    photo = file.read()

# create a user profile dictionary embedding the picture
now = datetime.now()
profile = {"name": "alex", "access_datetime": now, "photo": photo,
           "pi": 3.14, "books": ["Seul sur Mars", "The Fall"],
           "is_author": True, "fingerprint": None}

# create a dossier (or access an existing one)
path = Path(HOME, "my_dossier")
dossier = Dossier(path)

# save profile dictionary in the dossier
dossier.set("my_profile", profile)

# retrieve profile dictionary
profile_bis = dossier.get("my_profile")

# let's compare the two profile objects !
assert profile == profile_bis
