How it works

The bot fetches the data from the sources via different means. Afterward, the fetched data is formatted into a format that suits discord.

The news from Twitter and Stream are fetched via their respective api.

Facebook's api requirements are too strict for normal developers, so this bot scraps the content from their webpage.

Famitsu has no api, so web scraping is used here as well.

Set-Up

Following python modules are required to run this bot:

• discord.py - Discord interface
• pymongo - MongoDB interface
• bs4 - web scrapper library
• pygoogletranslation - news translation
• dnspython - requirement for pygoogletranslation
• emoji - required for seamless translations

Next to the modules following environment variables have to be set. For testing, this can also be done in settings.py

import os
# twitter login
os.environ["twitter_consumer_key"] = "twitter consumer key"
os.environ["twitter_consumer_secret"] = "twitter consumer secret"
# MongoDB login
os.environ["MDB_USER"] = "mongo db username"
os.environ["MDB_PASS"] = "mongo db password"
# Discord bot login
os.environ["DISCORD_BOT_TOKEN"] = "token of your discord bot"
