What's the purpose of this puts stuff?

[AlexWayfer]

You just copy the full output, paste it in GitHub, for example — that's all.

Example:

bundle exec rake benchmark

# frozen_string_literal: true

require "bundler/setup"
Bundler.setup

require "benchmark"
require "benchmark/ips"
require "benchmark/memory"

puts "```ruby"
puts File.read(__FILE__)
puts "```"
puts
puts "### Output"
puts
puts "```"

require_relative "lib/memery"

class Foo
  class << self
    include Memery

    def base_find(char)
      ("a".."k").find { |letter| letter == char }
    end

    memoize def find_new(char)
      base_find(char)
    end
  end
end

def test_memery
  Foo.find_new("d")
end

Benchmark.ips do |x|
  x.report("test_memery") { test_memery }
end

Benchmark.memory do |x|
  x.report("test_memery") { 100.times { test_memery } }
end

puts "```"
