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.

Usages
======

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)

    # OR, the same with increased verbosity:
    load_dotenv(dotenv_path, verbose=True)

Alternatively, you can use ``find_dotenv()`` method that will try to find a
``.env`` file by (a) guessing where to start using ``__file__`` or the working
directory -- allowing this to work in non-file contexts such as IPython notebooks
and the REPL, and then (b) walking up the directory tree looking for the
specified file -- called ``.env`` by default.

.. code:: python

    from dotenv import load_dotenv, find_dotenv
    load_dotenv(find_dotenv())

You can also set _load_dotenv_ to override existing variables:
.. code:: python

    from dotenv import load_dotenv, find_dotenv
    load_dotenv(find_dotenv(), override=True)

Now, you can access the variables either from system environment
variable or loaded from ``.env`` file. **System environment variables
gets higher precedence** and it's advised 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")


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

.. code:: shell

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

``.env`` can interpolate variables using POSIX variable expansion, variables
are replaced from the environment first or from other values in the ``.env``
file if the variable is not present in the environment. (``Note``: Default Value
Expansion is not supported as of yet, see `#30 <https://github.com/theskumar/python-dotenv/pull/30#issuecomment-244036604>`__.)

.. code:: shell

    CONFIG_PATH=${HOME}/.config/foo
    DOMAIN=example.org
    EMAIL=admin@${DOMAIN}


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!

::

    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.
      -q, --quote [always|never|auto]
                                      Whether to quote or not the variable values.
                                      Default mode is always. This does not affect
                                      parsing.
      --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.

iPython Support
---------------

You can use dotenv with iPython. You can either let the dotenv search for .env with `%dotenv` or provide the path to .env file explicitly, see below for usages.

::

    %load_ext dotenv

    # Use find_dotenv to locate the file
    %dotenv

    # Specify a particular file
    %dotenv relative/or/absolute/path/to/.env

    # Use _-o_ to indicate override of existing variables
    %dotenv -o

    # Use _-v_ to turn verbose mode on
    %dotenv -v


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
