class WeatherWatcher < Coolio::TimerWatcher
  API_KEY = 'YOUR_API_KEY'
  CITY_NAME = 'Tokyo'
  COUNTRY_CODE = 'JP'
  INTERVAL_SEC = 300

  def initialize
    super(INTERVAL_SEC, true)
  end

  def on_timer
    weather = get_weather
    icon_id = weather['weather'][0]['icon']
    temperature = weather['main']['temp']
    description = weather['weather'][0]['description']
    notify(icon_id, temperature, description)
  end

  def get_weather
    uri = URI('http://api.openweathermap.org')
