def check
  links = []
  read_file.each do |key, value|
    value["checked"] = Time.now
    if value["total"] < value["min"]
      puts "You're running low on #{key}!"
      links << key
    end
  end
  links.uniq!
  links.each { |link| buy(link)}
end

#config ⇒ Hash

Configure Stocker’s default settings If the –url param is not passed, no configurations will be changed.

Examples:

"nikki config --url 'http://amazon.com'"

Parameters:

  • --url (String) —

    Sets the default URL that is set for newly created inventory items

Returns:

  • (Hash) —

  settings = read_config
  settings['url'] = options[:url] || 'http://amazon.com'
  write_config(settings)
end

#count ⇒ Object

Do a count update for all inventory items interactively. Stocker#count will loop through the inventory and ask you for the total on hand count for each item. When the counting is finished, Stocker will run Stocker#check and open the URLs of any low stock items.
