【Ruby】簡単なスクリプトを書くならGemfileが不要になるbundler/inlineが便利

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  gem 'twitter'
end

client = Twitter::REST::Client.new do |config|
  config.consumer_key        = "YOUR_CONSUMER_KEY"
  config.consumer_secret     = "YOUR_CONSUMER_SECRET"
  config.access_token        = "YOUR_ACCESS_TOKEN"
  config.access_token_secret = "YOUR_ACCESS_SECRET"
end

user = client.user('takagi_blog')
puts "id: #{user.id}"
puts "name: #{user.name}"
puts "screen_name: #{user.screen_name}"

$ ruby app.rb
id: 1313842761204867072
name: 高木のブログ
screen_name: takagi_blog
