python-dotenv | [![Build Status](https://travis-ci.com/theskumar/python-dotenv.svg?branch=master)](https://travis-ci.com/theskumar/python-dotenv) [![Coverage Status](https://coveralls.io/repos/theskumar/python-dotenv/badge.svg?branch=master)](https://coveralls.io/r/theskumar/python-dotenv?branch=master) [![PyPI version](https://badge.fury.io/py/python-dotenv.svg)](http://badge.fury.io/py/python-dotenv) [![Say Thanks!](https://img.shields.io/badge/Say%20Thanks-!-1EAEDB.svg)](https://saythanks.io/to/theskumar)
===============================================================================
Reads the key-value pair from `.env` file and adds them to environment
variable. It is great for managing app settings during development and
in production using [12-factor](http://12factor.net/) principles.
> Do one thing, do it well!
## Usages
The easiest and most common usage consists on calling `load_dotenv` when
the application starts, which will load environment variables from a
file named `.env` in the current directory or any of its parents or from
the path specificied; after that, you can just call the
environment-related method you need as provided by `os.getenv`.
`.env` looks like this:
```shell
# a comment that will be ignored.
REDIS_ADDRESS=localhost:6379
MEANING_OF_LIFE=42
MULTILINE_VAR="hello\nworld"
```
You can optionally prefix each line with the word `export`, which is totally ignored by this library, but might allow you to [`source`](https://bash.cyberciti.biz/guide/Source_command) the file in bash.
```
export S3_BUCKET=YOURS3BUCKET
export SECRET_KEY=YOURSECRETKEYGOESHERE
```
Python-dotenv can interpolate variables using POSIX variable expansion.
The value of a variable is the first of the values defined in the following list:
- Value of that variable in the `.env` file.
- Value of that variable in the environment.
- Default value, if provided.
- Empty string.
Ensure that variables are surrounded with `{}` like `${HOME}` as bare
variables such as `$HOME` are not expanded.
```shell
CONFIG_PATH=${HOME}/.config/foo
DOMAIN=example.org
EMAIL=admin@${DOMAIN}
DEBUG=${DEBUG:-false}
```
## Getting started
Install the latest version with:
```shell
pip install -U python-dotenv
```
Assuming you have created the `.env` file along-side your settings
module.
.
├── .env
└── settings.py
Add the following code to your `settings.py`:
```python
# settings.py
from dotenv import load_dotenv
load_dotenv()
# OR, the same with increased verbosity
load_dotenv(verbose=True)
# OR, explicitly providing path to '.env'
from pathlib import Path # Python 3.6+ only
env_path = Path('.') / '.env'
load_dotenv(dotenv_path=env_path)
```
At this point, parsed key/value from the `.env` file is now present as
system environment variable and they can be conveniently accessed via
`os.getenv()`:
```python
# settings.py
import os
SECRET_KEY = os.getenv("EMAIL")
DATABASE_PASSWORD = os.getenv("DATABASE_PASSWORD")
```
`load_dotenv` does not override existing System environment variables. To
override, pass `override=True` to `load_dotenv()`.
`load_dotenv` also accepts `encoding` parameter to open the `.env` file. The default encoding is platform dependent (whatever `locale.getpreferredencoding()` returns), but any encoding supported by Python can be used. See the [codecs](https://docs.python.org/3/library/codecs.html#standard-encodings) module for the list of supported encodings.
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.
```python
from dotenv import load_dotenv, find_dotenv
load_dotenv(find_dotenv())
```
### In-memory filelikes
It is possible to not rely on the filesystem to parse filelikes from
other sources (e.g. from a network storage). `load_dotenv` and
`dotenv_values` accepts a filelike `stream`. Just be sure to rewind it
before passing.
```python
>>> from io import StringIO # Python2: from StringIO import StringIO
>>> from dotenv import dotenv_values
>>> filelike = StringIO('SPAM=EGGS\n')
>>> filelike.seek(0)
>>> parsed = dotenv_values(stream=filelike)
>>> parsed['SPAM']
'EGGS'
```
The returned value is dictionary with key-value pairs.
`dotenv_values` could be useful if you need to *consume* the envfile but
not *apply* it directly into the system environment.
### Django
If you are using Django, you should add the above loader script at the
top of `wsgi.py` and `manage.py`.
## IPython Support
You can use dotenv with IPython. You can either let the dotenv search
for `.env` with `%dotenv` or provide the path to the `.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
## Command-line Interface
For command-line support, use the CLI option during installation:
```shell
pip install -U "python-dotenv[cli]"
```
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 a 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.
-e, --export BOOLEAN
Whether to write the dot file as an
executable bash script.
--version Show the version and exit.
--help Show this message and exit.
Commands:
get Retrieve the value for the given key.
list Display all the stored key/value.
run Run command with environment variables present.
set Store the given key/value.
unset Removes the given key.
```
### Setting config on Remote Servers
We make use of excellent [Fabric](http://www.fabfile.org/) to accomplish
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.
```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
foo="bar"
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
