Ruby Language Gem Usage Bundler/inline (bundler v1.10 and later)
Example
Sometimes you need to make a script for someone but you are not sure what he has on his machine. Is there everything that your script needs? Not to worry. Bundler has a great function called in line.
It provides a gemfile method and before the script is run it downloads and requires all the necessary gems. A little example:
require 'bundler/inline' #require only what you need
#Start the bundler and in it use the syntax you are already familiar with
gemfile(true) do
source 'https://rubygems.org'
gem 'nokogiri', '~> 1.6.8.1'
gem 'ruby-graphviz'
end
