picobox 2.0.0

Why?

Because we usually want to decouple our code and Python lack of clean and pragmatic solutions (even third parties).

Features

• Support both values and factories.

• Support scopes (e.g. singleton, threadlocal).

• Push boxes on stack, and use the top one to access values.

• Thread-safe.

• Lightweight ( ~141 LOC ).

• Zero dependencies.

• Pure Python.

Quickstart

First

$ [sudo] python -m pip install picobox

and then

import picobox
import requests

@picobox.pass_('conf')
@picobox.pass_('requests', as_='session')
def get_resource(uri, session, conf):
    return session.get(conf['base_uri'] + uri)

box = picobox.Box()
box.put('conf', {'base_uri': 'http://example.com'})
box.put('requests', factory=requests.Session, scope=picobox.threadlocal)

with picobox.push(box):
    get_resource('/resource', requests.Session(), {})
    get_resource('/resource', requests.Session())
    get_resource('/resource')
