pebble-geocode-mapquest
pebble-geocode-mapquest provides an API to convert a location into coordinates using MapQuest's geocoding API.
Installation
pebble package pebble-geocode-mapquest
You must be using a new-style project; install the latest pebble tool and SDK
and run pebble convert-project
on your app if you aren't.
Usage
The following needs to be added to your app.js:
var GeocodeMapquest = require('pebble-geocode-mapquest');
var geocodeMapquest = new GeocodeMapquest();
Pebble.addEventListener('appmessage', function(e) {
geocodeMapquest.appMessageHandler(e);
});
// This is not a complete example, but should demonstrate the basic usage
#include <pebble-geocode-mapquest/pebble-geocode-mapquest.h>
static void geocode_fetch_callback(GeocodeMapquestCoordinates *coordinates, GeocodeMapquestStatus status) {
APP_LOG(APP_LOG_LEVEL_INFO, "%ld", coordinates->latitude);
APP_LOG(APP_LOG_LEVEL_INFO, "%ld", coordinates->longitude);
...
}
static void init(void) {
geocode_mapquest_init();
geocode_mapquest_set_api_key(GEOCODE_API_KEY);
geocode_mapquest_fetch("Seattle, WA", geocode_fetch_callback)
...
}
static void deinit(void) {
geocode_mapquest_deinit();
...
}
You must call geocode_mapquest_init()
first followed by geocode_mapquest_set_api_key()
, preferably
in your app's init function.
It is recommended to use a preprocessor define for your MapQuest API key instead of hard coding it, if
only to prevent it from being stored in your repo history:
CFLAGS="-DGEOCODE_API_KEY=\"thisismyapikey\" pebble build"
Before your app quits, you must call geocode_mapquest_deinit()
.
geocode_mapquest_fetch()
takes a location string and a callback with the results of the geocode operation.
If the operation failed for some reason that will be reflected in the status parameter to the callback.
geocode_mapquest_save()
and geocode_mapquest_load()
will save or load the most recent geocoding to
the specified key. This is a good way to avoid excessive calls to the MapQuest API. Save the results and refresh
only if the user specifies a different location.
