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: doc.rb
    path of file: ./repos/devdocs/lib/docs/core
    
    the code of the file until where you have to start completion: module Docs
  class Doc
    INDEX_FILENAME = 'index.json'
    DB_FILENAME = 'db.json'
    META_FILENAME = 'meta.json'

    class << self
      include Inst
    
      def store_pages(store)
        index = EntryIndex.new
        pages = PageDb.new

        store.replace(path) do
          new.build_pages do |page|
            next unless store_page?(page)
            store.write page[:store_path], page[:output]
            index.add page[:entries]
            pages.add page[:path], page[:output]
          end

          if index.present?
            store_index(store, INDEX_FILENAME, index)
            store_index(store, DB_FILENAME, pages)
            store_meta(store)
            true
          else
            false
          end
        end
