require_relative "rules"

# An object which represents the checkout process or cash register.
# It scans items, which are added to an internal list of items,
# which are then used to return the #total at any given moment.
# This total tries to use the rules which lead to the cheapest price.
class CheckOut < Struct.new(:rules)
  attr_accessor :rules  # list of available pricing rules (passed on initialization)
  attr_accessor :items  # hash of scanned items and quantities
                        # { "A" => 0, "B" => 1 } means we have scanned one "A" and zero "B"s

Introduction to git

What is git?
- git is basically, a version control system where you can collaborate with
  other and work on your projects. Developed by Linus.

Advantages of using git over other version system?
- git maintains snapshot of your projects, while other SVN store the diff for every change.
- git uses SHA1, so data loss is almost impossible (checks for data integrity).
- git maintains the local database, so the search is faster as compare to other.
