Perl ForecastIO module README for GitHub

ForecastIO.pm

This Perl wrapper API is used to process weather data that is provided in JSON format by forecast.io.

Related: forecast.io developer API info. From the forecast.io website:

"The easiest, most advanced, weather API on the web. The same API that powers Forecast.io and Dark Sky for iOS can provide accurate short­term and long­term weather predictions to your business, application, or crazy idea."

A working example that uses this Perl module can be found at Toledo Weather. This weather Web app uses jQuery mobile on the client side. Several Perl scripts execute at different intervals in cron that fetch RSS, custom XML, and HTML files from the National Weather Service to provide the data for display. The forecast.io section of this Web app uses a small part of this Perl module. Code for the entire Toledo weather Web app exists on GitHub at ToledoWX.

Perl Module

This Perl module was inspired by the PHP forecast.io wrapper located at tobias-redmann/forecast.io-php-api.

Usage

View the test Perl script in the bin directory.

perl use ForecastIO;

Set your API key and location.

perl my $forecast = ForecastIO->new($api_key, $latitude, $longitude);

Download JSON data and convert it to a Perl hash.

perl $forecast->fetch_data;
