Exercise 12 - Learn Ruby the Hard Way

gistfile1.rb

# the command require is requiring the library open-uri so we can use particular things from it 
require 'open-uri'

# the method open is opening the url;
# the method "do" will enact the defined method stated after f
# to each of the lines that follow 
open("http://www.ruby-lang.org/en") do |f|
    f.each_line {|line| p line}
    puts f.base_uri         # <URI::HTTP:0x40e6ef2
    puts f.content_type     # "text/html"
    puts f.charset          # "iso-8859-1"
    puts f.content_encoding # {}
    puts f.last_modified    # Thurs. Dec. 05 02:25 URC
