Dirty little ruby script to get oEmbed from URLs, for use with automator actions in Mac OSX. Enables embedding Tweets and Flickr photos (and probably others) for selected URLs. Rather fragile.

oembed.rb

require 'rubygems'
require "open-uri"
require 'nokogiri'
require 'json'

ARGV.each do |f|
  doc = Nokogiri::HTML(open(f))
  doc.css('link[type="application/json+oembed"]').each do |link|
    oembed_uri = link['href']
    oembed = open(oembed_uri).read
    j = JSON.parse(oembed)
    if j["type"] == "rich"
      puts "#{j["html"]}\n\n"
    elsif j["type"] == "photo"
      puts "<p><a href=\"#{j["web_page"]}\" title=\"#{j["title"]}\"><img src=\"#{j["url"]}\" alt=\"#{j["title"]}\" width=\"#{j["width"]}\" height=\"#{j["height"]}\"></a></p>\n"
      puts "<p>"
      puts "By <a href=\"#{j["author_url"]}\">#{j["author_name"]}</a>." if j["author_name"]
      puts "On <a href=\"#{j["provider_url"]}\">#{j["provider_name"]}</a>." if j["provider_name"]
      puts "</p>\n"
    end
  end    
end
