Inline Bundler Without Gemfile

#ruby

For quick throwaway ruby scripts, you can add your gemfile inline. When you run the file, ruby will install your dependencies and then execute the script.

Inline bundler

# BEGIN inline bundler 
require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'

  gem 'httparty'
  gem 'pry'
end
# END inline bundler 

resp = HTTParty.get "https://rubygems.org"
binding.pry
