A Better Quoting System [Live Coding Recap]

#python #beginners #livecoding #twitch

Streamed: 10/27 on Twitch

Topic(s): We created a persistent data system for the Twitch Bot
Language: Python, JSON
Tech & libs used: VSCode, TwitchIO

👇 You can find the code we wrote on stream down below! :D

⭐ Star ⇒ Project Repository
💜 Follow ⇒ on Twitch and GitHub
🔴 Watch ⇒ Twitch VOD (replay)

During the stream we...

✔ unboxed the a hat from DEV!! Ty!!
✔ changed voice on tts to Brian
✔ moved !project command to DeepThonk
✔ get !quoth partially working
✔ handled a case of key-errors
✔ tested out the fixes - it works!
✔ worked on vscode for the next live coding article for a bit
✔ ended the night playing video games w/community

Making the quote system

We made a command called !quoth that takes a user name as an argument and saves the last thing that user said as a quote.

BestCoderNA: I'm not totally useless. I can be used as a bad example!
F1SavesLives: !quoth @BestCoderNA
QUOTE SAVED: "I'm not totally useless. I can be used as a bad example!" - @BestCoderNA

Here's the entry point to the quoth feature. It's an async command registered in the bot's event loop. You invoke it by sending !quoth in chat.

# commands.py @bot.command(name="quoth") async def quoth(ctx): 'the raven, nevermore. nevermore.' token = ctx.content.split(' ', 1) # tokenize™  author = token[1].lower() # match case for msg database keys  if author[0] == '@': # strip the @ if tagged  author = author[1:] data.quoth(author)

Every message sent in chat is added to a dictionary with a key of the user name.

# called in event_message(): def save_last_message(self, author, msg): if msg[0] == '!': # ignore commands  return if msg[0] == '@': # strip tags if tagged  author = author[1:] self.last_message[author] = msg log.debug(f"saved: {author} - {self.last_message[author]}")

In our data object, which is our JSON "database" interface, we use the quoth method to append the python quote to a list of quotes.

# in the `data` object, an instance of DataInterface def quoth(self, author): 'take in an author name and add the last thing said from them' try: # check if they've even said anything yet  incoming_quote = { "author" : author, "quote" : self.last_message[author] } except KeyError: log.debug(f"{author} hasn't said anything yet...") # pull the json data to an object  with open('quotes.json') as json_file: data = json.load(json_file) quotes = list() for quote in data: quotes.append(quote) # add all the quotes from json to a list  quotes.append(incoming_quote) # add the new quote to the end of the list  log.debug(f"QUOTE SAVED! {incoming_quote}") # rewrite with the new quote  with open('quotes.json', 'w+') as json_file: json.dump(quotes, json_file, indent=4) # dump it back in to jso
Enter fullscreen mode Exit fullscreen mode

And here's the JSON "database" after we tested it out with a few quotes!

[ { "author": "Jigokuniku", "quote": "TBH, some best practices are really only ever learned by getting annoyed at the bad practice" }, { "author": "NinjaBunny9000", "quote": "JUST 👏 BECAUSE 👏 IT'S 👏 EATABLE 👏 DOESN'T 👏 MEAN 👏 IT'S 👏 EDIBLE 👏" }, { "author": "J0nnyclueless", "quote": "I sometimes get kernel panic attacks" }, { "author": "Sockelo", "quote": "Forgive them, for they know not what they compile." } ]
