Rails how to create an initializer inside a gem

Question

I am trying to build a gem in Rails 3 and inside it i am trying to pass an initializer:

Credentials.configure do |config|
  file = File.read(\"#{Rails.root}/

Your gem will first need to define a generator in lib/generators/your_gem_name_generator.rb

mkdir -p lib/generators/

Copy your initializer in that folder with a name like twitter_credentials.rb

Then create another file in that folder with a name like twitter_generator.rb with content like this:

class YourGemNameRailtie < Rails::Generators::Base
  source_root(File.expand_path(File.dirname(__FILE__)))
  def copy_initializer
    copy_file 'twitter_credentials.rb', 'config/initializers/twitter_credentials.rb'
  end
end

You should check out the official documentation for creating a generator here: http://guides.rubyonrails.org/generators.html
