Parse RailsConf calendar into iCal format

railsconf.rb

#!/usr/bin/env ruby

require 'rubygems'

require 'nokogiri'
require 'open-uri'

require 'icalendar'
require 'date'

include Icalendar

cal = Calendar.new
cal.custom_property("X-WR-CALNAME;VALUE=TEXT", "RailsConf 2012")
cal.custom_property("X-WR-TIMEZONE;VALUE=TEXT", "America/Chicago")

doc = Nokogiri::HTML(open('http://railsconf2012.com/sessions'))
doc.css('.session,.keynote').each do |session|
  event = Event.new
  event.summary = session.css('h4').text
  stuff  = session.css('h5')
  stuff1 = stuff.first.text
  time, event.location = stuff1.split(' in ')
  event.start = DateTime.parse(time)
  event.end = event.start + 1/24.0
  event.organizer = stuff[1] ? stuff[1].text.gsub(/by /, '') : ''
  event.description = session.css('p').collect {|p| p.text}.join("\n\n")
  cal.add_event(event)
end

puts cal.to_ical
  

Excellent!

I'm lousy with iCal, but wanted to share the steps I used (after some trial and error):
Create a new calendar in iCal for this (I used an iCloud calendar named RailsConf2012 for easy sync to iPhone)
In prefs turn off any default alert.
Save the results of this as railsconf.ics.
Double-click and then choose RailsConf2012 as the calendar to receive them
Re-enable default alert
