Tweet Shenmue 3 Funds

This script scraps Shenmue 3's website, using Nokogiri and open-uri, for funds data updates. It saves the data to a database, using PostgreSQL via pg. It compares the data between the database and the website, and if new data is found, then it creates an image, using blitline and an image template (as given with the ENV 'IMG_SRC'). It also creates the text to be tweeted on Twitter (specifically on @ShenmueLegacy), using twitter. The text is tweeted together with the image (example).

The code of this project is very expressive and easilly understandable (as self-documented code), using the associative data logic of hashes.

In our case, we are using Heroku to host this project.
