Installation

pip install sqlean-driver

Usage

from sqlalchemy import create_engine, func, select

engine = create_engine("sqlite+sqlean:///:memory:?extensions=all")

with engine.connect() as conn:
    result = conn.execute(select(func.ipfamily("192.168.1.1")))
    print(result.scalar())  # 4

Extensions

By default, sqlean.py disables all SQLite extensions. To enable all of them, pass extensions=all as a query parameter to the connection string. Or use a comma-separated list of extensions to enable only some of them, e.g. extensions=ipaddr,crypto.

Alternatives

Note that you don't strictly need this driver to use sqlean.py with SQLAlchemy. You can supply sqlean as the module parameter to create_engine:

import sqlean
from sqlalchemy import create_engine, func, select

sqlean.extensions.enable_all()
engine = create_engine("sqlite:///:memory:", module=sqlean)

with engine.connect() as conn:
    result = conn.execute(select(func.ipfamily("192.168.1.1")))
    print(result.scalar())  # 4

Development

This project uses Hatch to manage the development environment, so make sure you have it installed.
