rails console で reload! した時に lib も再読み込みするやつ

rails_console_lib_reaload.rb

if defined?(Rails)
  lib = File::join(Rails.root, 'lib')
  ActiveSupport::Dependencies.autoload_paths << lib
  Dir[lib + '/**'].each do |f|
    class_name = File.basename(f).sub(/\.rb$/, '').camelize
    ActiveSupport::Dependencies.explicitly_unloadable_constants << class_name
  end
end
