  AwesomePrint.pry!

.pryrc.rb

# Copy this to ~/.pryrc

# Sublime as default editor
Pry.config.editor = "sublime-text"

# Prompt with ruby version
Pry.prompt = [proc { |obj, nest_level| "pry[#{RUBY_VERSION}] (#{obj}):#{nest_level} > " }, proc { |obj, nest_level| "#{RUBY_VERSION} (#{obj}):#{nest_level} * " }]

For just IRB/AwesomePrint, you can do:

unbundled_require 'awesome_print' do
  AwesomePrint.irb!
end
