Settings::Env::Loader

Scan ENV and override correspondong settings in a nested Hash

The Hash must provide all configuration options. It eases the deployment to platform such as heroku.

It is recommended to use settingslogic to load settings first, and then merge ENV into it.

Installation

Add this line to your application's Gemfile:

gem 'settings-env-loader'

And then execute:

$ bundle

Or install it yourself as:

$ gem install settings-env-loader

Usage

Extend hash object:

hash.extend SettingsEnvLoader

Call merge_env

hash.merge_env

Use each_env to export all configuratable options:

hash.each_env do |k, v|
  puts "export #{k}=#{v.inspect}"
end
