Dashing Weather Widget

Description

A Dashing widget to display weather information using World Weather Online API and Skycons

Preview

Useage

To use this widget, copy forecast.coffee, forecast.html, and forecast.scss into the /widgets/forecast directory of your Dashing app. This directory does not exist in new Dashing apps, so you may have to create it. Copy the forecast.rb file into your /jobs folder, and include the Skycons library, skycons.js, in your assets/javascripts directory. Edit the forecast.rb file to include your World Weather Online API key and your zip code.

To include the widget in a dashboard, add the following to your dashboard layout file:
