Wunder
Weather information via the Weather Underground API. Intended for use on an iPhone, but I'm sure the GPS stuff can be adapted to Android.
CGI script
The CGI script, wunder.py, takes the latitude and longitude as parameters and generates a web page with
- A local radar image centered 1° west of the location. I'm used to weather coming from the west.
- The current conditions and today's sunrise and sunset.
- The forecast for the next twelve hours, given at three-hour intervals.
- Forecasts for the next two days, given at four-hour intervals.
The script requires a Weather Underground key that's saved in the wukey variable on Line 187.
HTML file
The HTML file, wunderlocal.html, uses the iOS Geolocation class to access the GPS data via JavaScript and uses the latitude and longitude to construct a URL that calls wunder.py.
Both the wunder.py and wunderlocal.html must be put on a server where they're accessible via a web browser. Depending on how your web server is configured, you may need to change the extension on wunder.py to make it executable. Whatever its name, you'll need to edit Line 11 of wunderlocal.html to set the wURL variable to the URL of the CGI script.
Home screen buttons
To create a home screen button for a fixed location, just enter a URL of the form
http://path/to/wunder.py?lat=yy.yyy&lon=-xx.xxx
where yy.yyy and -xx.xxx are the latitude and longitude of the location in decimal degrees. After the page loads, use the Share button and the Add to Home Screen command to create an icon on your home screen that opens Safari immediately to the weather page for that location.
Creating a home screen button that gives you the weather for your current location is a little trickier. First, comment out the <script> in Lines 17–19 of wunderlocal.html. Then uncomment the <h1> on Line 21. Then go to
http://path/to/wunderlocal.html
in Safari. Because of the commenting/uncommenting, it won't show any weather data, but that's OK. Go ahead and use Add to Home Screen again to make an icon on your home screen linked to that URL.
Once you've made the home screen button, go back into wunderlocal.html and uncomment Lines 17–19 and comment out Line 21, putting the file back into its original state. Now when you tap the home screen button, it'll redirect you to a weather info page for your current location. You'll probably be asked for permission for the page to access your location.
