[isc-utils] Weather, Exchange Rate, Temperature, Length in a snap

Hi developers!

When @Evgeny Shvarov announced the first InterSystems IRIS Programming Contest, I started looking for new ideas.  

I put together a few ideas, and that's what isc-utils is about.

  •  Conversions
    • Temperature
    • Length
  • Exchange Rate
  • Weather

 

Temperature Scale Conversion

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToFahrenheit(28)
82.4

IRISAPP>write ##class(diashenrique.Utils.Temperature).CelsiusToKelvin(28)
301.15

IRISAPP>write ##class(diashenrique.Utils.Temperature).FahrenheitToCelsius(82.4)
28

IRISAPP>write ##class(diashenrique.Utils.Temperature).FahrenheitToKelvin(82.4)
301.15

IRISAPP>write ##class(diashenrique.Utils.Temperature).KelvinToCelsius(301.15)
28

IRISAPP>write ##class(diashenrique.Utils.Temperature).KelvinToFahrenheit(301.15)
82.37

Length Scale Conversion

IRISAPP>write ##class(diashenrique.Utils.Length).KmToMiles(120)
74.58

IRISAPP>write ##class(diashenrique.Utils.Length).MilesToKm(74.58)
120

Parameters:

  • Amount
  • Base Currency Eg. JPY
  • Exchange rates
    • ALL - for all currencies available in the API
    • Request specific exchange rates. Eg.: "BRL,AUD,CAD,RUB"

ByDate

IRISAPP>do ##class(diashenrique.Utils.ExchangeRate).ByDate("2020-01-01",1,"USD","BRL,JPY,AUD,CAD")
Date: 2020-01-01
Conversion of 1 USD

JPY Japanese yen            108.545
AUD Australian dollar         1.424
CAD Canadian dollar           1.299

Parameters:

  • Date = YYYY-MM-DD
  • Amount
  • Base Currency Eg. BRL
  • Exchange rates
    • ALL - for all currencies available in the API
    • Request specific exchange rates, Eg. "BRL,AUD,CAD,RUB"

There is a global ^defaultCurrency, that'll keep your preferred base currency.

So, you can call the ClassMethod Latest, without any parameter:

IRISAPP>do ##class(diashenrique.Utils.ExchangeRate).Latest()
Default Base Currency: 

Just inform your preferred base currency:

IRISAPP>do ##class(diashenrique.Utils.ExchangeRate).Latest()
Default Base Currency: USD

Date: 2020-03-18

Weather

IRISAPP>do ##class(diashenrique.Utils.Weather).GetWeather()
Default City: 
Default Country: 
Default Termo Scale(C,F,K): 

The ClassMethod GetWeather, also has preferred options. For Default possibilities we have:

  • City
  • Country
  • Thermal Scale (Celsius, Fahrenheit or Kelvin)
IRISAPP>do ##class(diashenrique.Utils.Weather).GetWeather()
Default City: Boston
Default Country: USA
Default Termo Scale(C,F,K): F

City: Boston | Country: USA

Temperature: 53.46 °F
Real Feel: 46.02 °F
Condition: Clear

But, you can consult any other city sending the parameters:

IRISAPP>do ##class(diashenrique.Utils.Weather).GetWeather("Sao Paulo","Brazil","C")
City: Sao Paulo | Country: Brazil

Temperature: 27.55 °C
Real Feel: 28.4 °C
Condition: Rain

After defining the default parameters, they become optional:

IRISAPP>do ##class(diashenrique.Utils.Weather).GetWeather("Sao Paulo","Brazil")
City: Sao Paulo | Country: Brazil

Temperature: 82.17 °F
Real Feel: 83.95 °F
Condition: Rain
