A simple post this time. Corripio is a program for OS X that lets you easily find album artwork for your music collection. However, it’s a bit rough around the edges and its built in web based mechanisms for retrieving this artwork are rather limited and frankly a bit rubbish. I’ve managed to solve all these issues by writing a plugin to fix its unaccountable lack of support for Google Images.

However, a word to the wise: this is probably against the terms of service, so make sure you only use this plugin for personal use!


require 'net/http'
require 'open-uri'
require 'uri'
require 'cgi'

# Construct a query for good-sized Google images by taking the supplied keywords and adding "album"
query = (ARGV + ["album"]).join(" ")
sizes = ["medium", "large", "xlarge"].join("|")
uri = "http://images.google.co.uk/images?hl=en&q=#{CGI.escape(query)}&imgsz=#{CGI.escape(sizes)}"

source = open(URI.parse(uri)).read.gsub("\r\n", "")

# Look for javascript statements of the form dyn.Img("foo", "bar", "lol", "http://www.example.com/yay.jpg")
matcher = /dyn.Img\(".*?",".*?",".*?","(.*?)"/
matches = source.scan(matcher)

# Push back the best 10 results
matches.first(10).each { |match| puts match.first }

To install the plugin, copy the above code into a new file in ~/Library/Application Support/Corripio/Plugins and make sure it is marked executable. Now, you can drag that file into the Plugins section of the Corripio preference pane and then (optionally) disable the default image search plugins. When you’re done the preferences pane should look something like this:
