Library for interacting with the Weather Underground JSON API.

Weather is a simple library for interacting with the Weather Underground JSON API. It is not complete, but it may be useful still.

weather

Haskell library for working with the Weather Underground JSON API.

Currently only supports querying for conditions for US-based cities.

Example usage:

{-# LANGUAGE RecordWildCards #-}

module Main where

import Web.Weather

mykey :: APIKey
mykey   = "top-secret"

mycity, mystate :: String
mycity  = "Detroit"
mystate = "MI"

main :: IO ()
main = do
  resp <- getConditions mykey mycity mystate
  case resp of
   Nothing -> putStrLn "No data for that city/state"
   Just (Observation{..}) -> do
     putStrLn $ "Observation time: " ++ obsTime
     putStrLn $ "Weather conditions: " ++ obsWeather
     putStrLn $ "Temp: " ++ show obsTemp
     putStrLn $ "Rel humidity: " ++ show obsRelHumidity
     putStrLn $ "Wind: " ++ obsWind
     putStrLn $ "Feels like: " ++ obsFeelsLike

Output:

Observation time: Last Updated on April 10, 2:09 PM EDT
Weather conditions: Partly Cloudy
Temp: 52.9
Rel humidity: "60%"
Wind: From the West at 4.7 MPH
Feels like: 52.9 F (11.6 C)
