A Ruby Gem that wraps the Weather Channel, inc. XML data feed written by Jared Pace, Codeword: Studios (codewordstudios.com), based on the rweather gem by Carlos Kozuszko - www.ckozus.com.ar/blog/.

1. XmlSimple

   gem install xml-simple
   

% sudo gem sources -a http://gems.github.com # (if you haven't already)
% sudo gem install jdpace-weatherman

Find or load a location:

require 'weather_man'
WeatherMan.partner_id = '0123456789'
WeatherMan.license_key = '0123456789abcdef'

# Search for a location
# Returns an array of WeatherMan objects
locations = WeatherMan.search('New York')

# or if you know the location id or just want to use a US Zip code
ny = WeatherMan.new('USNY0996')

Fetch the weather:

# Fetch the current conditions and 5 day forecast in 'standard' units
weather = ny.fetch

# Fetch only current conditions in metric units
weather = ny.fetch(:days => 0, :unit => 'm')

# Fetch a 3 day forecast only
weather = ny.fetch(:days => 3, :current_conditions => false)

Look at the Current Conditions:

# current temperature
temp = weather.current_conditions.temperature

feels_like = weather.current_conditions.feels_like

wind_speed = weather.current_conditions.wind.speed
wind_direction = weather.current_conditions.wind.direction

Look at the forecast:

# how many days?
weather.forecast.size

# Some different forecasts
weather.forecast.today
weather.forecast.tomorrow
weather.forecast.monday
weather.forecast.for(Date.today)
weather.forecast.for(3.days.from_now) # Note: using rails core extensions
weather.forecast.for('Sep 1')

# data for a forecast
friday = weather.forecast.friday

high_temp = friday.high
low_temp = friday.low

# forecasts are split into 2 parts day/night
friday.day.description # Partly Cloudy, Sunny...
friday.day.chance_percipitation # 0..100

night_wind_speed = friday.night.wind.speed

The Weather Channel requires that you 4 promotional links for them if you use their service. Here’s how to access those links:

# The array of pr links
weather.links

# Getting the first links text and url
weather.links.first.text
weather.links.first.url
