• Open Automator and choose “Service” from the first menu.
• Tell it that the service “receives text” in “any application”.
• Drag the “Run Shell Script” action from the left side.
• Set the Shell to Ruby
• Paste in the code below (or something of your own, hopefully far more interesting)
• Save it with an intuitive name
• Use it.

require 'net/http'
require 'cgi'
 
input = STDIN.read
http = Net::HTTP.new('to.')
path = '/'
 
data = "url=#{CGI.escape(input.strip)}"
headers = {'Content-Type' => 'application/x-www-form-urlencoded'}
 
resp, data = http.post(path, data, headers)
 
if resp.code.to_i == 200
  print data.split(/value="/)[1].split(/"/)[0]
else
  print input
end

Basically, anything you can do to or with text or files using a major scripting language, you can make into a Snow Leopard service. Now that I’ve set the bar this low, I’d love to see what new Services everyone else is cooking up!

Update: Yeah, that didn’t work out so well. It works sometimes, but leaves url parameters in the shortened url half the time. I haven’t figured out why, but I’ll leave it up and see if someone can point out the error of my ways…Fixed it, just neglected to notice it needed a POST, not a GET

Update 2: Here, this one’s shorter and more useful :)

require 'open-uri'
require 'cgi'
 
input = STDIN.read
print open("http://is.gd/api.php?longurl=#{CGI.escape(input.strip)}").read
