Project description

A helping hand to manage your settings among different environments

## Intro

Managing application configuration that runs on multiple environments
can be tough. So **milieu** comes to help you pretend you have only
one settings file that magically works whenever you deploy.

## Production

The system environment is the first place **milieu** will try to find
things. So, when the application runs inside of an environment with the right
variables set, it will just work.

So, if you know you have the environment variable `DATABASE_URI` like this:

$ export DATABASE_URI=mysql://root@localhost:3306/mydb

The application settings glue code will look like this:

>>> from milieu import Environment
>>> env = Environment()
>>> dburi = env.get_uri('DATABASE_URI')
>>> dburi.port

## Local

If you just want to load things from a file locally, the
`Environment.from_file()` constructor will help you out.

>>> from milieu import Environment
>>> env = Environment.from_file('/etc/app.cfg')
>>> env.get_bool('BOOL_FLAG')
>>> env.get_float('FLOAT_VAL')

The file `app.cfg` will look like this:



## From a folder

You can also load variables from a folder, where each file will be an
environment variable and the file's content will be the value. Just
like [envdir](

Now, say that you have the folder `/etc/envdir/app` and this folder
contains the file `MYSQL_CONN_URI` with a database URL inside of
it. Just like this one here:

To read that directory and load the variable properly, you just have
to do the following:

>>> from milieu import Environment
>>> env = Environment.from_folder('/etc/envdir/app')
>>> uri = env.get_uri('MYSQL_CONN_URI')
>>> uri.port
>>> uri.user
>>> uri.password

# Hacking on it

## Install dev dependencies

pip install -r requirements-dev.txt

## Run tests

make test

## Change it

Make sure you write tests for your new features and keep the test
coverage in 100%

## Release it

After you already made your commits, run:

make release

follow the instructions and do the
[harlem shake](
