Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

Worth noting that I have an IRC client monitoring the IRCd and the channel #test, nothing appears on that client's end when the test client is ran

[opaque pulsar]

is it possible you're missing the \r\n after each line?

[clever swan]

Do I actually have to send a CRLF after each line?

[opaque pulsar]

yes

otherwise they get all treated as one single line

[clever swan]

Well I'll be damned, that did something

[opaque pulsar]

TCP is a stream.

with TCP you have to always assume, that you might not receive the complete data, or sometimes multiple pieces of data are merged

(hough you're using readline(), so that's doing it for you automatcally.)

[clever swan]

Hm, the servers sending :localhost.com 451 TestNyte_ :You have not registered

[opaque pulsar]

not sure what thath means. are you using one of those NickServ services? Or maybe the USER command did not work?

[clever swan]

Perhaps it's because the PASS being sent is nonsensical with an anonymous user

[opaque pulsar]

it's been a while since I last used IRC 😄 (aside from twitch chat)

possibly

[clever swan]

Ah lovely it works now

Had to fix the PONG response and actually set up the client password to comply with how I set up the IRCd

[opaque pulsar]

    async def _loop(self):
        buf = b''
        while True:
            data = await self._reader.readline()
            if not data:
                print('Connection closed')  # no data = EOF
                break

            # collect all data in a buffer
            buf += data.replace(b'\r', b'\n')  # now we only need to deal with \n

            while b'\n' in buf:
                # split out a line and keep the rest in buf (maxsplits+loop condition ensures there will be exactly two elements)
                line, buf = buf.split(b'\n', maxsplits=1)
                if line.startswith(b'PING '):  # respond with the exact same message, but as PONG
                    await self.send(line.replace(b'PING', b'PONG', 1) + b'\r\n')
                    continue

                plaintext = line.decode('utf-8')  # this might still fail, as IRC doesn't define any encoding
                logging.debug(f"Received: {plaintext}")
                yield line

    async def mainloop(self):
        async for line in self._loop():
            print(line)


``` here a sample of how to do it if you can't use .readline() 😄
(plus an example how to yield your lines in an async for loop)

---

you might eant to add a "sendline" method, and use that one for everything instead instead.
