def load_env(env_data, definition)
  config = {}
  definition.env.each do |env_key, config_key|

    next unless env_data.key?(env_key)
    config[config_key] = env_data[env_key]
  end
  config
end

#populate(data = {}) ⇒ Object

This converts a definition into a hash of configuation values. It does this using the following steps

  1. load config data from a yaml or json file if a file is defined

  2. populate all children

  3. merge defaults into config data that has been given or resolved from the config file

  4. merge override data into the results from step 3

  5. run validation and assign clean data to config with the key

Parameters:

  • data (defaults to: {}) —

    Hash holds overrides and config source data

Returns:

  • Hash
