Get me some temperatures for screen's backtick!

outside_temp.rb

#!/usr/bin/env ruby
# encoding: UTF-8
require 'rubygems'

# https://github.com/jnunemaker/google-weather/
# gem install google-weather
require 'google_weather'

# usage: outside_temp.rb [City,Province|Postal Code]
if ARGV.size == 0
	city = "Vancouver,BC"
else
	city = ARGV[0]
end

weather = GoogleWeather.new(city)

# I'd like to append ℃ or °, but screen seems to mangle Unicode?

puts "#{weather.current_conditions.temp_c}C"
