這串Getting Real學習筆記是別人寫的，實際上是非常的不筆記，想快速瀏覽Getting Real這本書在表達些什麼，可以去瞧瞧。

用了半天時間翻完Ruby for Rails，感想是，學Ruby請讀Programming Ruby: The Pragmatic Programmer's Guide，學Rails請讀Agile Web Development with Rails，讀完Agile Web Development with Rails可以再讀Rails Recipes，不要把時間耗在Ruby for Rails上。

This is my first Ruby script to fetch photos from TaipeiLink.

#!/usr/local/bin/ruby
require "net/http"

if ARGV.length == 0
 puts "tplink.rb <account>"
 exit
end


ARGV.delete("tplink.rb")
ARGV.each { |account|
 puts "Fetching photos from #{account}..."
 Dir.mkdir(account) if !FileTest.exist?(account)
 Net::HTTP.start("photo.taipeilink.net", 80) { |http|
   http.get("/#{account}").body.scan(/<a href="http://photo.taipeilink.net/#{account}?st=album&pg=(d*)"/) { |pg|
     Dir.mkdir("#{account}/#{pg}") if !FileTest.exist?("#{account}/#{pg}")
     http.get("/#{account}?st=album&pg=#{pg}").body.scan(/<a href="http://photo.taipeilink.net/#{account}/(d*-d*-d*-d*)?m=0&pg=(d*)"/) { |fileName, pg|
       url = "/#{account}/#{fileName}?m=1&pg=#{pg}"
       response = http.head(url)
       if response["content-type"] == "image/gif"
         fileName += ".gif"
       else
         fileName += ".jpg"
       end
       fileName = "#{account}/#{pg}/#{fileName}"
       if FileTest.exist?(fileName)
         puts "Skip #{fileName}"
       else
         puts "Fetch #{fileName}"
         response = http.get(url)
         file = File.new(fileName, "w")
         file.write(response.body)
         file.close()
       end
     }
   }
 }
}
