python-dotenv
=============

|Build Status| |Coverage Status| |PyPI version| |PyPI|

Reads the key,value pair from ``.env`` and adds them to environment
variable. It is great of managing app settings during development and in
production using `12-factor <http://12factor.net/>`__ principles.

    Do one thing, do it well!

Usages
======

``.env`` is a simple text file. With each environment variables listed
per line, in the format of ``KEY="Value"``

::

   SECRET_KEY="your_secret_key"
   DATABASE_PASSWORD="your_database_password"
   ...

If you want to be really fancy with your env file you can do comments
(below is a valid env file)

.. code:: shell

    # I am a comment and that is OK
    SOME_VAR=someval
    FOO=BAR

Assuming you have created the ``.env`` file along-side your settings
module.

::

    .
    ├── .env
    └── settings.py

Add the following code to your ``settings.py``

.. code:: python

    # settings.py
    from os.path import join, dirname
    from dotenv import load_dotenv

    dotenv_path = join(dirname(__file__), '.env')
    load_dotenv(dotenv_path)

Now, you can access the variables either from existing environment
variable or loaded from ``.env`` file. ``.env`` file gets higher
precedence, and it's adviced not to include it in version control.

.. code:: python

    # settings.py

    SECRET_KEY = os.environ.get("SECRET_KEY")
    DATABASE_PASSWORD = os.environ.get("DATABASE_PASSWORD")

Django
------

If you are using django you should add the above loader script at the
top of ``wsgi.py`` and ``manage.py``.

Installation
============

::

    pip install -U python-dotenv

Command-line interface
======================

A cli interface ``dotenv`` is also included, which helps you manipulate
the ``.env`` file without manually opening it. The same cli installed on
remote machine combined with fabric (discussed later) will enable you to
update your settings on remote server, handy isn't it!

.. raw:: html

   <pre>
   $ dotenv
   Usage: dotenv [OPTIONS] COMMAND [ARGS]...

     This script is used to set, get or unset values from a .env file.

   Options:
     -f, --file PATH  Location of the .env file, defaults to .env file in current
                      working directory.
     --help           Show this message and exit.

   Commands:
     get    Retrive the value for the given key.
     list   Display all the stored key/value.
     set    Store the given key/value.
     unset  Removes the given key.
   </pre>

Setting config on remote servers
--------------------------------

We make use of excellent `Fabric <http://www.fabfile.org/>`__ to
acomplish this. Add a config task to your local fabfile, ``dotenv_path``
is the location of the absolute path of ``.env`` file on the remote
server.

.. code:: python

    # fabfile.py

    import dotenv
    from fabric.api import task, run, env

    # absolute path to the location of .env on remote server.
    env.dotenv_path = '/opt/myapp/.env'

    @task
    def config(action=None, key=None, value=None):
        '''Manage project configuration via .env

        e.g: fab config:set,<key>,<value>
             fab config:get,<key>
             fab config:unset,<key>
             fab config:list
        '''
        run('touch %(dotenv_path)s' % env)
        command = dotenv.get_cli_string(env.dotenv_path, action, key, value)
        run(command)

Usage is designed to mirror the heroku config api very closely.

Get all your remote config info with ``fab config``

::

    $ fab config

Set remote config variables with ``fab config:set,<key>,<value>``

::

    $ fab config:set,hello,world

Get a single remote config variables with ``fab config:get,<key>``

::

    $ fab config:get,hello

Delete a remote config variables with ``fab config:unset,<key>``

::

    $ fab config:unset,hello

Thanks entirely to fabric and not one bit to this project, you can chain
commands like so ``fab config:set,<key1>,<value1> config:set,<key2>,<value2>``

::

    $ fab config:set,hello,world config:set,foo,bar config:set,fizz=buzz
