In a recent stream, DougDoug taught Atrioc and Aimen gamin to program. They went through a few fun little exercises in Python, like building a custom little hotkey program. The last exercise would connect to each stream's chat, listen to cheers (donations), and run the streamer's code. Atrioc and Aimen would be the ones to implement what would happen for each donation.
As far as I know, Twitch doesn't really provide a very good way to check if a message contains a cheer or get how much it is for. That's going off of anecdotal evidence, I don't know what it looks like now and quite frankly I'm too lazy to go check.
So in this case, DougDoug had to implement his own check to see if a message contains a cheer. Effectively, the check is if a space delimited word starts with one of a few words like "cheer" and ends with a number. For example, "cheer100" would cheer 100 bits (cents). This is implemented like this:
words = message.content.lower().split()
for word in words:
# Common cheer patterns: cheer100, kappa50, pogchamp25, etc.
if any(word.startswith(cheer) for cheer in ['cheer', 'kappa', 'pogchamp']):
# Extract number from the end of the cheer
import re
match = re.search(r'(\d+)$', word)
if match:
try:
bits_amount += int(match.group(1))
except (ValueError, TypeError):
passThis is the brief piece of code that I saw on Atrioc's stream and I almost couldn't believe my eyes. This code implements the check described above, but critically it only implements the check from above. The word only needs to start with "cheer" and end with a number. Anything can be in the middle, so for example, "cheerc100" would be registered as a cheer for 100 bits without actually charging me money.
Now, at first I was under the presumption that this code was called for somewhere that already knew the message contained a cheer. In that case, this code is really good at finding the amount of bits in the message. However, this code is run on every message in chat and at that, as a fallback in case a different way of checking if the message contains a cheer doesn't find one.
Come to find out, DougDoug commit the code for this stream to Github. So I moseyed my little 'ol self on over to his Github and wouldn't you know it, my intuition was right. You can put ANYTHING in the middle of "cheer" and any number and the program will assume it's an actual cheer.
After my initial test, there were a flurry of "cheerc1000000000000000000" as you would imagine. I was just proud that my intuition was right to be honest. Nothing too serious or crazy here, just wanted to write up what this was. And to give my professional opinion, this stream was definitely Cinema
