Picobox is opinionated dependency injection framework designed to be clean,
pragmatic and with Python in mind. No complex graphs, no implicit injections,
no type bindings – just picoboxes, and explicit demands!


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, contextvars).
* Push boxes on stack, and use the top one to access values.
* Thread-safe.
* Lightweight (~500 LOC including scopes).
* Zero dependencies.
* Pure Python.
* Annotated with types.



Quickstart
----------

First

.. code:: bash

    $ [sudo] python -m pip install picobox

and then

.. code:: python

    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")
