module Schrank

Returns true when the application is in development mode, otherwise returns false.

@return [Boolean]

# File lib/schrank.rb, line 48
def self.development?
  ((defined?(Rails) && Rails.env) || ENV['RACK_ENV'] || ENV['APP_ENV']) == 'development'
end

Attempts to load YAML file. Falls back on defaults hash when file is not found.

In development mode, the defaults hash is merged with the YAML file, with the file taking precedence. This is intentional, since it allows shared config to live in your application source code, but per-user secrets (such as access keys) can be kept in a file and out of version control.

@example Simply load your config.

config = Schrank.load(Rails.root.join('config/production.yml'))

@example Load your config, providing defaults.

config = Schrank.load(Rails.root.join('config/production.yml')) do
  {
    provider: 's3',
    prefix: 'folder/'
  }
end

@param [String] path The path to the config file @yieldreturn [Hash] Default config @return [ActiveSupport::HashWithIndifferentAccess]
