Discord-Wikipedia-Bot

Add this bot to the server and let it help you get Wikipedia summaries and URLs on your server using the '!' prefix

Before getting into the code, I use the Discord Developer Portal to create an application and bot to get the token and Client ID, so that I can connect the bot to run stipulated series of code later on.

Initialisation

To start off, I initiate these modules to lay the foundations in order to set up a Discord client.

import wikipedia
import os
import discord
from dotenv import load_dotenv

Subsequently, I intialise the Discord bot via the load_dontenv function and TOKEN variable so that the Discord bot is able to connect and run the code and algorithms below.

load_dotenv()
TOKEN = os.getenv('insert_bot_token_here')

Finally, I initialise the client variable to set up the Discord bot.

client = discord.Client()

Coding the Bot

Before you do any coding, make sure you invite the bot to your own Discord server copying this link: https://discord.com/oauth2/authorize?client_id=IDHERE&scope=bot. Replace "IDHERE" in "client_id=IDHERE" with your own bot Client ID. The following code below will output whether the Discord bot is connected to the server or not.

@client.event
async def on_ready():
    print(f'{client.user} has connected to Discord!')

The code below allows the bot to read user messages and respond in a manner as programmed.

@client.event
async def on_message(message):
    if message.author == client.user:
        return
    if '!search' in message.content:
        response = wikipedia.summary(message.content[8:])
        if len([char for char in response]) >= 2000:
            response = wikipedia.summary(message.content[8:], sentences=15)
            await message.channel.send(str(response))
        else:
            await message.channel.send(str(response))
    if '!help' in message.content:
        response = '!help to summon commands\n\n!search to search wikipedia\n\n!url to get wikipedia url'
        await message.channel.send(response)
    if  '!url' in message.content:
        response = wikipedia.page(message.content[5:]).url
        await message.channel.send(response)

The bot will respond to a ping if the user sends a message "!ping". The user can retrieve Wikipedia summaries using the command "!search". This is done via the wikipedia.summary() function from the wikipedia module.

Disclaimer: Some terms may not be searchable or the content is way too long to be messaged on your server's text channel. Thus, the bot is only programmed to send a maximum of 15 sentences from the Wikipedia summary.

The user can retrieve Wikipedia URLs using the command "!url". This is done via the wikipedia.page().url

Finally, I run the Discord client client.run('insert bot token here')
