[IT CAN NOT GO BEYOND TWITTER 3200 LIMIT, SO USE IT REGULARLY, PDF IS IN YOUR HOME DIRECTORY]
tweets2pdf is an opensource lightweight python application to back up your twitter timeline, favorates, retweets, others' timelines and favorites, generally every type of tweet, into an elegent book formated properly in PDF. It requires python imaging and reportlab module, at first use you have to oauth it(unluckily for Chinese still no proxy added). It can also back up your replies to your friends(although still unluckily not in thread or conversation mode). Future works may forcus on import feature so you can import your previous backups in csv, json, html, xml or sql formats you kept from other backup utilities and generate a book covers your full twitter life. It looks like a local fork of tweetbook.in or other similar on line services, but we're actually the first based on time! And we support tweets in other character encodings, because the author @levin108 himself is not a native speaker either. Any artwork or code support will be greatly appreciated.
