class App

Initialises the App class @param wanted_temperature [wanted_temperature] the desired room temperature @param range [range] the range in wich the room temperature must stay from the desired temperature @param thermostat [thermostat] an instance from the class Thermostat @param update_speed [update_speed] the speed at wich the app will run

# File lib/app.rb, line 11
def initialize(args)
  @wanted_temperature = args[:wanted_temperature]
  @range = get_range(input_range: args[:range])
  @thermostat = args[:thermostat]
  @update_speed = args[:update_speed] || 1
end

Checks if the thermostat must cool down to reach the desired temperature @param temperature [temperature] the current room temperature @return [Boolean] true if the thermostat had to cool down if not, false

# File lib/app.rb, line 49
def cool_thermostat(args)
  if temperature_out_of_range(temperature: args[:temperature]) &&
     temperature_to_high(temperature: args[:temperature])
    thermostat.cooling(value: range)
    true
  else
    false
  end
end

says the thermostat if it must heat up or cool down to reach the desired temperature @return [Struct] contains what actions the thermostat took

# File lib/app.rb, line 38
def correct_temperature
  cooling = cool_thermostat(temperature: thermostat_temperature)
  heating = heat_thermostat(temperature: thermostat_temperature)
  output = Struct.new(:cooling, :heating)
  output.new(cooling, heating)
end

gets the range value used in calculations @param input_range [input_range] the range in wich the room temperature must stay from the desired temperature @return [number] the actual range

# File lib/app.rb, line 31
def get_range(args)
  args[:input_range] / 2.0
end

Checks if the thermostat must heat up to reach the desired temperature @param temperature [temperature] the current room temperature @return [Boolean] true if the thermostat had to warm up if not, false

# File lib/app.rb, line 63
def heat_thermostat(args)
  if temperature_out_of_range(temperature: args[:temperature]) &&
     temperature_to_low(temperature: args[:temperature])
    thermostat.heating(value: range)
    true
  else
    false
  end
end

Starts the application

# File lib/app.rb, line 19
def run
  loop do
    print("\ntermostaat temperatuur: #{thermostat_temperature}")
    correct_temperature
    sleep(update_speed)
  end
end

Checks if the temperature is out of range @param temperature [temperature] the current room temperature @return [Boolean] true if the thermostat is out of range else, false

# File lib/app.rb, line 76
def temperature_out_of_range(args)
  (args[:temperature] - wanted_temperature).abs > range
end

Checks if the temperature is to high @param temperature [temperature] the current room temperature @return [Boolean] true if the temperature is to high else, false

# File lib/app.rb, line 90
def temperature_to_high(args)
  args[:temperature] > wanted_temperature
end

Checks if the temperature is to low @param temperature [temperature] the current room temperature @return [Boolean] true if the temperature is to low else, false

# File lib/app.rb, line 83
def temperature_to_low(args)
  args[:temperature] < wanted_temperature
end

gets the current temperature of the thermostat @return [number] the current thermostat temperature

# File lib/app.rb, line 96
def thermostat_temperature
  thermostat.temperature
