ConfigFile

The ConfigFile gem handles configuration file loading and validation.

Installation

Add this line to your application's Gemfile:

gem 'config_file'

And then execute:

$ bundle

Or install it yourself as:

$ gem install config_file

Usage

Raise an error if config file or certain keys are missing:

c = ConfigFile.new("./config/mandrill.yml")
c.validate_existence!
c.validate_key!('api_key', /\A\w{22}\Z/)

Mandrill.api_key = c.data['api_key']

Only use a warning in dev or test environment:

ConfigFile.configure do |c|
  c.env = ENV['WEBKITE_ENV'] # default to :dev if nil
  c.alias_env(:default, :dev) # use alias for keys in file
  c.alias_env(:development, :dev)
end

c = ConfigFile.new("./config/mandrill.yml", dev: :warn, test: warn)
c.validate_existence!
=> nil

c.validate_key!('api_key', /\A\w{22}\Z/)
=> nil

Mandrill.api_key = c.data['api_key']
=> nil
