# change prompt_name to rails project name if available
if defined? Rails
  Pry.config.prompt_name = Rails.application.class.parent_name.underscore.dasherize

This combines two techniques I shared before:

• http://ascendbruce.logdown.com/posts/205967-using-irbrc-to-serve-frequent-used-commands-in-rails-console
• http://ascendbruce.logdown.com/posts/208604-awesome-rails-console-customization-using-pry

This is helpful for people who want to customize rails console but not permitted to add those gems into Gemfile.
