Easy loading of environment variables in Elixir

Envy

A simple Elixir library to load environment variables from .env and environment specific env files like .env.dev, .env.test, etc.

Installation

Add envy to your dependencies in mix.exs.

def deps do
  [{:envy, "~> 0.0.1"}]
end

Usage

To load env files you have two options, you can use the autoloader or give the library paths to specific files to load itself.

Using auto_load you can add the following to your application:

unless Mix.env == "prod" do
  Envy.auto_load
end

This will look for .env and the mix env specific file. For example if your applications Mix.env is dev then envy will attempt to load .env.dev

You can also specify which files to load manually using Envy.load which accepts a list of files to attempt to load.

Envy.load([".env"])

To export FOO as bar you can add the following line to your env file.

foo=bar

Comments can be added with a #.

foo=bar # comments

If you need to use # in your values you can use double quotes.

tag="#bar" #comments
