Create a TalkBot easily using Discord.py and A3RT's Talk API (pya3rt).

In the afternoon, I tried various things using a certain Discord.py, There was a person saying this on Discord's server. ** "I want Talking !!" ** Talking-kun is a TalkBot on Discord that is kind to me and has no conversation partner that I often saw for a while ... By the way, there was a free API called A3RT. Alright, let's make it.

Precautions for the time being.

The person who writes this is a Python beginner, so there may be some points that cannot be reached. At that time, please be kind .... Also, this is Qiita's first post. I look forward to working with you. ~~ This is a cat. ~~

environment

Regarding the environment, it is considerably outlaw compared to the bot like the article in Qiita, so if you refer to this, please adjust it to your own environment.

• discord.py 1.3.0
• Python 3.7.2 --I share an event loop on Heroku to spin multiple bots. --I am using the Bot Commands Framework and Cog.

Thing you want to do

If you speak on a specific channel, it will react unconditionally → Return it with Talk API of A3RT.

Then do it.

A3RT API KEY issuance

You can easily issue an API KEY by sending an email from the TalkAPI page. I will use it later.

Write the contents of the bot.

run.py like this.

run.py

import discord
from discord.ext import commands
import asyncio
import os
import sys
import traceback

loop = asyncio.get_event_loop()

airlinia_token = os.environ['AIRLINIA_DISCORD_TOKEN'] #Environment variables ~~.
technetium_token = os.environ['TECHNETIUM_DISCORD_TOKEN']

class DISCORDBOT(commands.Bot):
    #constructor.
    def __init__(self, command_prefix, cogs, **options):
        #Execute by passing a value to the constructor of the superclass.
        super().__init__(command_prefix, **options)
        #In the cog folder.Read the py file.
        for cog in os.listdir(f'./{cogs}'):
            if cog.endswith('.py'):
                try:
                    self.load_extension(f'{cogs}.{cog[:-3]}')
                except Exception:
                    traceback.print_exc()

    async def on_ready(self): #Call when ready.
        print(f"""You are now logged.
        ------\nBot account overview\n Username:{self.user.name}\n User ID:{self.user.id}
        ------\nDiscord.version of py\n{discord.__version__}
        ------\Python version\n{sys.version}
        ――――――――――――――――――――――――――――――""")
        await self.change_presence(activity=discord.Game(name=f'{self.command_prefix}￤{self.user.name} - by.amazakura0804'))

if __name__ == '__main__':
    airlinia = DISCORDBOT(command_prefix='al!', cogs='airlinia_cogs', loop=loop)
    airlinia_task = loop.create_task(airlinia.start(airlinia_token))

    technetium = DISCORDBOT(command_prefix='te!', cogs='technetium_cogs', loop=loop)
    technetium_task = loop.create_task(technetium.start(technetium_token))

    loop.run_until_complete(technetium_task)
    loop.run_until_complete(airlinia_task)
    loop.close()

While referring to Bot development using Bot Commands Framework of discord.py. TOKEN is an environment variable. Please change here depending on the environment. I won't move more than one. I think that this kind of feeling is enough.

run.py

import discord
from discord.ext import commands
import asyncio
import os
import sys
import traceback

token = os.environ['DISCORD_TOKEN']

class HogeBot(commands.Bot):
    #constructor.
    def __init__(self, command_prefix, cogs, **options):
        #Execute by passing a value to the constructor of the superclass.
        super().__init__(command_prefix, **options)
        #In the cog folder.Read the py file.
        for cog in os.listdir(f'./{cogs}'):
            if cog.endswith('.py'):
                try:
                    self.load_extension(f'{cogs}.{cog[:-3]}')
                except Exception:
                    traceback.print_exc()

    async def on_ready(self): #Call when ready.
        print(f"""You are now logged.
        ------\nBot account overview\n Username:{self.user.name}\n User ID:{self.user.id}
        ------\nDiscord.version of py\n{discord.__version__}
        ------\Python version\n{sys.version}
        ――――――――――――――――――――――――――――――""")
        await self.change_presence(activity=discord.Game(name=f'{self.command_prefix}￤{self.user.name} - by.amazakura0804'))

if __name__ == '__main__':
    hogebot = HogeBot(command_prefix='!', cogs='hogebot_cogs')
    hogebot.run(token) #Bot token

Talk.py

Talk.py

import discord
from discord.ext import commands
import asyncio
import os
import pya3rt

class Talk_Bot(commands.Cog):
    def __init__(self, airlinia):
        self.bot = airlinia #Receive a bot.

    @commands.Cog.listener()
    async def on_message(self, message):
        if message.author.bot:  #Fly the bot's message
            return
        if message.channel.id == TALK_CHANNEL_ID: #Replace with CHANNEL ID that you want to speak as appropriate.
            client = pya3rt.TalkClient(os.environ['TALK_API_KEY']) #This is also an environment variable, so it is omitted below.
            content = client.talk(message.content)['results'][0]['reply']
            await message.channel.send(content) #Send a reply message

def setup(airlinia):
    airlinia.add_cog(Talk_Bot(airlinia))

Yes. A3RT is odd. Try applying the A3RT API KEY to an environment variable or inserting it directly. With just this code ...

Yay. God. Thank you Recruit.

Finally

By using various APIs including A3RT, the range of things that can be done will expand considerably. There are many other things that seem interesting, so I would like to take advantage of them.
