How could I include these requires among multiple scripts - ruby

Question

I have lots of scripts need to include the same header.
What's the better way to include them in every script
# -*- encoding : utf-8 -*-
#!/usr/bin/ruby
require 'yaml'
require "json"
require 'pry'
require "selenium-webdriver"
require 'nokogiri'
require 'active_support/all'
require 'yaml'
require 'date'
require 'awesome_print'
require 'mongo'
require File.expand_path('./form_action.rb', File.dirname(__FILE__))
require File.expand_path('./schedule_manager.rb', File.dirname(__FILE__))
require File.expand_path('../common_helper.rb', File.dirname(__FILE__))
require File.expand_path('../mongodb_helper.rb', File.dirname(__FILE__))
require File.expand_path('../webdriver_helper.rb', File.dirname(__FILE__))
require File.expand_path('../lib/db_manager.rb', File.dirname(__FILE__))
require File.expand_path('../lib/app_util.rb', File.dirname(__FILE__))
require File.expand_path('../lib/schedule_manager_base.rb', File.dirname(__FILE__))
require File.expand_path('../lib/class_template.rb', File.dirname(__FILE__))
include Mongo
include MongodbHelper
include AppUtil
Project folder structure
I will include the common_includes in client1.rb,
But the SIBLINGS not work.
├── common_helper.rb
├── common_includes.rb
├── config
│   ├── database.yml
│   └── schedule.rb
├── client1
│   ├── config.yml
│   ├── client1.rb
│   └── schedule_manager.rb
└── webdriver_helper.rb
├── lib
│   ├── app_util.rb
│   ├── class_template.rb
│   ├── db_manager.rb
│   └── schedule_manager_base.rb

Put smth like following:
REQUIRES = %w(yaml json pry selenium-webdriver nokogiri active_support/all yaml date awesome_print mongo)
SIBLINGS = %w(form_action schedule_manager)
COMMON = %w(common_helper mongodb_helper webdriver_helper db_manager.rb lib/app_util lib/schedule_manager_base lib/class_template.rb)
INCLUDES = %i(Mongo MongodbHelper AppUtil)
REQUIRES.each &method :require
SIBLINGS.each do |f|
File.expand_path("./#{f}.rb", File.dirname(__FILE__))
end
COMMON.each do |f|
File.expand_path("../#{f}.rb", File.dirname(__FILE__))
end
module CommonIncludes
def self.included base
INCLUDES.each { |inc| base.include Kernel.const_get(inc) }
end
end
into a very file common_includes.rb and everywhere you need it, call:
require 'common_includes'
include CommonIncludes
This is more or less common approach to require/include in case you need to specify the file list explicitly one by one.
NB To manage external dependencies, everyone wants to use bundler, as mentioned Mike Slutsky around.
UPD Don’t hesitate to use Dir["./*.rb"] to collect all the files for a given directory.

If I am understanding your question correctly, you are looking for a way that you can include all these headers without having to copy and paste them all over the place.
One way you can achieve this is to put all these headers into one file, and in your scripts just include that file:
For example, in headers.rb:
# -*- encoding : utf-8 -*-
#!/usr/bin/ruby
require 'yaml'
require "json"
require 'pry'
require "selenium-webdriver"
require 'nokogiri'
require 'active_support/all'
require 'yaml'
require 'date'
require 'awesome_print'
require 'mongo'
require File.expand_path('./form_action.rb', File.dirname(__FILE__))
require File.expand_path('./schedule_manager.rb', File.dirname(__FILE__))
require File.expand_path('../common_helper.rb', File.dirname(__FILE__))
require File.expand_path('../mongodb_helper.rb', File.dirname(__FILE__))
require File.expand_path('../webdriver_helper.rb', File.dirname(__FILE__))
require File.expand_path('../lib/db_manager.rb', File.dirname(__FILE__))
require File.expand_path('../lib/app_util.rb', File.dirname(__FILE__))
require File.expand_path('../lib/schedule_manager_base.rb', File.dirname(__FILE__))
require File.expand_path('../lib/class_template.rb', File.dirname(__FILE__))
include Mongo
include MongodbHelper
include AppUtil
Then your scripts:
require 'path/to/headers'
