To listen to messages that your app has access to receive, you can use the message() method which filters out events that aren't of type message.
message() accepts an argument of type str or re.Pattern object that filters out any messages that don’t match the pattern.
# This will match any message that contains 👋
@app.message(":wave:")
def say_hello(message, say):
user = message['user']
say(f"Hi there, <@{user}>!")The re.compile() method can be used instead of a string for more granular matching.
import re
@app.message(re.compile("(hi|hello|hey)"))
def say_hello_regex(say, context):
# regular expression matches are inside of context.matches
greeting = context['matches'][0]
say(f"{greeting}, how are you?")
