load takes a string or hash as input, strings are treated as filenames hashes are stored as data that would have been in the config file
Unless specified it will only use YAML as backend with a single 'common' hierarchy and console logger
@return [Hash] representing the configuration. e.g.
{:backends => "yaml", :hierarchy => "common"}
# File lib/hiera/config.rb, line 12 def load(source) @config = {:backends => "yaml", :hierarchy => "common"} if source.is_a?(String) if File.exist?(source) config = begin yaml_load_file(source) rescue TypeError => detail case detail.message when /no implicit conversion from nil to integer/ false else raise detail end end @config.merge! config if config else raise "Config file #{source} not found" end elsif source.is_a?(Hash) @config.merge! source end @config[:backends] = [ @config[:backends] ].flatten if @config.include?(:logger) Hiera.logger = @config[:logger].to_s else @config[:logger] = "console" Hiera.logger = "console" end @config end

::yaml_load_file directly delegates to YAML.load_file and is intended to be a private, internal method suitable for stubbing and mocking.
@return [Object] return value of {YAML.load_file}
