What is this project ?

This project is about the development of a Go package using OpenWeatherMap to get and manipulate current weather datas from a wished city in a wished country. It is the second (and final) version of the weathermodule Go project.

How to use it ?

go get -u github.com/Vicken-Ghoubiguian/weathermodule_v2

This will retrieve the library.

A little example

package main

// import all necessary packages
import (
	"github.com/Vicken-Ghoubiguian/weathermodule_v2"
	"fmt"
)

// main function to test all of the package
func main() {

	//
	var weatherObj weathermodule_v2.WeatherModule

	weatherObj.InitializeWeatherModule("<wished_city_name>", "<wished_country_code>", "<Your_OpenWeather_Map_API_key>")

Conclusion

It has been an exciting project, easily usable by anyone in any other project written in Go language regardless of its size (large or small) and which has broadened my knowledge in Go language development as potentially every other beginner or confirmed developer.
