Library for easy fetching of weather data from OpenWeatherMap.org.

Includes a simple test app as a proof of concept usage of a weather C API.

• Obtain an API key from OpenWeatherMap.org.

• Ensure 'enableMultiJS': true is set in your appinfo.json.

• Add owm_weather/owm_weather.js to /src/js/lib, include it in your your app.js file, and then instantiate an OWMWeather object.

var OWMWeather = require('lib/owm_weather.js');
var owmWeather = new OWMWeather();

• Call owmWeather.appMessageHandler() in an appmessage handler so that it can message the C side.

Pebble.addEventListener('appmessage', function(e) {
  owmWeather.appMessageHandler(e);
});

• Copy the owm_weather directory into your project's src directory and include the library in any C files that will use it:

#include "owm_weather/owm_weather.h"

• Call owm_weather_init(api_key) to initialize the library when your app starts, supplying your API key.

• Call owm_weather_fetch() after PebbleKit JS is ready, and supply a suitable callback for events.

That's it! When the fetch returns (successful or not), the callback will be called with a OWMWeatherInfo object for you to extract data from.

By default, the OWMWeather library requires 11 consecutive unused App Message Keys (and defaults to 0 - 10). If you wish to use a different set of consecutive keys, you can set the AppKey base by changing the JavaScript and C initializers to:

var OWMWeather = require('lib/owm_weather.js');

// Use App Keys 10-20
var owmWeather = new OWMWeather({ appKeyBase: 10 });

// Use App Keys 10-20
owm_weather_init_with_base_app_key(apiKey, 10);

NOTE: You must set the AppKey base in both the C and JS application code to use this feature.

Read owm_weather/owm_weather.h for function and enum documentation.
