Fastenv

Fast access to environment variables. Takes advantage of method_missing to easily return values of environment variable.

Why? Because TYPING_IN_ALL_CAPS isn't fun or readable.

Installation

Add this line to your application's Gemfile:

gem 'fastenv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fastenv

Usage

Say you have an environment variable

WORDPRESS_USERNAME="La-de-da-de-da"

You can access it from your Ruby code as simply as

require 'fastenv'

Fastenv.wordpress_username

If the environment variable doesn't exist, a NameError will be raise.

Fastenv is intended for querying credentials. Missing credentials is an exceptional event.

Defaults

It can be helpful to specify default values though. You can give Fastenv a block, and, if the environment variable is not set, the block will be evaluated and its value returned.

require 'fastenv'

your_special_value = Fastenv.env_does_not_exist { 'but this is a default' }
=> "but this is a default"

---

Goes Well With

Pair it with dotenv to easily set and retrieve your credentials from environment variables.

# .env
WORDPRESS_USERNAME="TweedleDee"
WORDPRESS_PASSWORD="password"

# your_app.rb
require 'dotenv'
Dotenv.load

require 'fastenv'

credentials = {
  username: Fastenv.wordpress_username,
  password: Fastenv.wordpress_password }
# => {:username=>"TweedleDee", :password=>"password"}
