module ConfigFor

Loads yaml file “#{{name}}.yml” from path and gets given environment key. In case the environment is not found, it returns empty hash.

@param [Pathname, String] path partial of full path to folder with configs @param [String] name without extension @param [Symbol,String] env key to get from the config @raise [ConfigFor::InvalidConfigError] when the config is invalid YAML @raise [ConfigFor::ReadError] when the config can't be read @return [ActiveSupport::HashWithIndifferentAccess] config file for given env @example Load config in rails

ConfigFor.load_config(Rails.root.join('config'), 'redis', Rails.env)

# File lib/config_for.rb, line 27
def self.load_config(path, name, env)
  config(path, name).fetch(env) { ConfigFor::Config.empty }
end

Same as ConfigFor.load_config but raises exception when environment is not found. Note that this is the preferred way of loading configuration. Also it is used by Rails and Sinatra integrations.

@param (see .load_config) @raise (see .load_config) @raise [ConfigFor::MissingEnvironmentError] when the config does not have the environment key @return (see .load_config)

# File lib/config_for.rb, line 39
def self.load_config!(path, name, env)
  config(path, name).fetch(env)
end

  ConfigFor::Config.new(path, name)
