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
π You can find the code we wrote on stream down below! :D
β Star β Project Repository
π Follow β on Twitch and GitHub
π΄ Watch β Twitch VOD (replay)
During the stream we...
β unboxed the a hat from DEV!! Ty!!
β changed voice on tts to Brian
β moved !project command to DeepThonk
β get !quoth partially working
β handled a case of key-errors
β tested out the fixes - it works!
β worked on vscode for the next live coding article for a bit
β 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) # tokenizeβ’
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
And here's the JSON "database" after we tested it out with a few quotes!
