You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: input_store.rb
    path of file: ./repos/lookbook/lib/lookbook/stores
    
    the code of the file until where you have to start completion: module Lookbook
  class InputStore
    CONFIG_FILE = "config/inputs.yml"

    DEFAULTS = {}

    attr_reader :store

    
    def build_config(name, *args)
      partial = nil
      opts = nil
      if args.many? && args.last.is_a?(Hash)
        partial = args.first
        opts = args.last
      elsif args.first.is_a?(String)
        partial = args.first
      end
