WeatherApp

Simple passive-aggressive CLI app that calls OpenWeatherMap API to get information about the current weather in a given location.

About

WeatherApp is a simple Java CLI app that calls OpenWeatherMap API to get information about the current weather in a given location. The location can be passed in two ways: by a location name or its coordinates.

Getting Started

Set-up

To properly function, WeatherApp requires an OpenWeatherMapAPI key to be placed in the "key.txt" file, in the ...src/main/java/WeatherApp directory. For extra security, the file should be placed in the .gitignore file. If you want to use the extra functionality, you will also need to place an InsultAPI key in the "insultKey.txt" file, in the same directory.

Usage

The app can be run from the command line by typing java -jar WeatherApp.jar in the .../target directory.

It needs to be run with one of the following arguments:

• -l or --location - the location for which the weather information is requested. The location should be specified by city name (e.g. London) or
• -c or --coordinates - the coordinates for which the weather information is requested. The coordinates should be specified by latitude and longitude (e.g. 51.5074 0.1278)

Optional arguments

• -w or --writeToFile - the app will write the weather information to a file. Specify the file name after the argument (e.g. -w fileName)
• -i or --insultMe - the app will insult you. Specify your name after the argument (e.g. -i John) and insult type (e.g. -i John insult) or (e.g. -i John praise).

To get help, run the app with the -h or --help argument.

Example program calls

• java -jar WeatherApp.jar -l London
• java -jar WeatherApp.jar -l New York
• java -jar WeatherApp.jar -l Warsaw -w fileName
• java -jar WeatherApp.jar -c 51.5074 0.1278
• java -jar WeatherApp.jar -c 51.5074 0.1278 -w fileName
• java -jar WeatherApp.jar -c 51.5074 0.1278 -i John insult
• java -jar WeatherApp.jar -c 51.5074 0.1278 -i John praise

Output

The app will output the following information:

Temperature: [temperature] Celsius degrees
Humidity: [humidity]%
Pressure: [pressure] hPa
Wind Speed: [wind speed] m/s
