# frozen_string_literal: true
require "bundler/compatibility_guard"
# Allows for declaring a Gemfile inline in a ruby script, optionally installing
# any gems that aren't already installed on the user's system.
#
# @note Every gem that is specified in this 'Gemfile' will be `require`d, as if
# the user had manually called `Bundler.require`. To avoid a requested gem
# being automatically required, add the `:require => false` option to the
# `gem` dependency declaration.
#
# @param install [Boolean] whether gems that aren't already installed on the
# user's system should be installed.
# Defaults to `false`.
#
# @param gemfile [Proc] a block that is evaluated as a `Gemfile`.
#
# @example Using an inline Gemfile
#
# #!/usr/bin/env ruby
#
# require 'bundler/inline'
#
# gemfile do
# source 'https://rubygems.org'
# gem 'json', require: false
# gem 'nap', require: 'rest'
# gem 'cocoapods', '~> 0.34.1'
# end
#
# puts Pod::VERSION # => "0.34.4"
