Roboragi is a Reddit bot (found at /u/Roboragi which creates anime and manga links from MAL, Hummingbird, Anilist, MangaUpdates and Anime-Planet when requested.
Roboragi is written in Python for use with Python 3. There's a requirements.txt if you want to test it out yourself, but you'll need to create a Config.py with your own information and set up a PostgreSQL database. I highly recommend changing the subredditlist variable in AnimeBot.py to a private subreddit that only you and the bot have access to (otherwise you'll respond to everything the actual Roboragi bot does).
Roboragi uses PRAW (a Python library) to interface with Reddit through the /u/Roboragi account. It searches through constant stream of comments and checks each of those for requests for the correct symbols - {}, {{}}, <> and <<>>. Once it's identified that it's being called, it takes the stuff between the braces and does a search for it in various anime/manga databases. Once it's got as much as it can find, the objects generated by the various databases are sent off to be formed into a comment. That then gets sent back to Reddit to be commented through PRAW and /u/Roboragi.
