Connect to the BBC Backstage (backstage.bbc.co.uk) weather API and get weather observations and forecasts for thousands of cities worldwide. No login is required to the BBC for use.
-
Allow weather to be shown in either metric or imperial units (currently only metric)
-
Be able to seach or lookup location ids
-
Add weather sources other than the BBC
After requiring the library, create a WeatherReport object with a BBC weather location id:
require 'weather_report' # 8 is the BBC Backstage weather code for London, UK londonWeather = WeatherReport.new(8)
Then you can get the observations or forecasts for that location:
londonWeather.observation.temperature londonWeather.forecast.for_tomorrow.max_temperature
Calls to the observation or forecast data after the first call for a location will just return return cached data. Use force_reload = true on the call to force the data to be reloaded from the BBC.
# use the cached data londonWeather.observation.reading_date # reload the data londonWeather.observation(force_reload = true).reading_date
Forecasts can be specified in a number of ways:
londonWeather.forecast.for_tomorrow.max_temperature londonWeather.forecast.for_today.max_temperature # also today londonWeather.forecast.for(Date.today).max_temperature # day after tomorrow londonWeather.forecast.for(Date.today+2).max_temperature # The date can also be specified as a date string londonWeather.forecast.for("2009-05-06").max_temperature # The underlying structure is an array, so you can just index into it. The below is the same as today londonWeather.forecast[0].max_temperature
The full set of attributes is:
londonWeather.observation.reading_date londonWeather.observation.name londonWeather.observation.country londonWeather.observation.latitude londonWeather.observation.longtitude londonWeather.observation.temperature londonWeather.observation.wind_speed londonWeather.observation.wind_direction londonWeather.observation.humidity londonWeather.observation.pressure londonWeather.observation.pressure_state londonWeather.observation.visibility londonWeather.observation.humidity londonWeather.observation.description londonWeather.forecast.reading_date londonWeather.forecast.name londonWeather.forecast.country londonWeather.forecast.latitude londonWeather.forecast.longtitude londonWeather.forecast.image_url londonWeather.forecast.for_today.date londonWeather.forecast.for_today.max_temperature londonWeather.forecast.for_today.min_temperature londonWeather.forecast.for_today.wind_speed londonWeather.forecast.for_today.wind_direction londonWeather.forecast.for_today.humidity londonWeather.forecast.for_today.pressure londonWeather.forecast.for_today.visibility londonWeather.forecast.for_today.humidity londonWeather.forecast.for_today.description londonWeather.forecast.for_today.advance_days
The only external dependencies are REXML and net/http which are included as part of most Ruby installations.
The weather_report library is distributed itself as a RubyGem and is available immediately after installation.
sudo gem install weather_report
Alternately, download the gem here or the tgz here and install manually.
