Does anyone here know how I can listen to messages in a specific room with Python? e.g. like Smokey listens to messages here?

user12986714

@Daniil Looks like there is a websocket you can listen to

thesecretmaster

@Daniil github.com/Manishearth/ChatExchange

user435118

@thesecretmaster I saw that and read the docs but have no idea how to use it.

user435118

3:37 PM

@user12986714 What websocket would that be?

double-beep

4:04 PM

@Daniil it isn't stable

you have to get the url

user435118

So do I just get the room URL and scrape the response for the latest messages?

double-beep

@Daniil that doesn't sound like a good idea to me.

Makyen

@Daniil It's complex. Is there a reason you don't want to use the ChatExchange package, like SmokeDetector does?

user435118

@Makyen I don't mind, it's just I don't know how to use it (and yes, I've read the docs).

Makyen

@Daniil No, if you just want to get the latest existing messages, then there's an API route that can get the existing messages in a room, but that route isn't a notification of new activity.

user435118

4:18 PM

@double-beep Probably not, I just got a response with everyone's email_hashes :/

user435118

@Makyen I would prefer that, but again, I need someone to tell me how to use it :)

double-beep

@Daniil see github.com/thomas-daniels/SO-EditMonitor/blob/master/… and github.com/thomas-daniels/SO-EditMonitor/blob/master/…

Makyen

@Daniil Using that API route would be polling, which is a very poor substitute for being notified of new activity. If you just want existing events, and don't care about new messages, then use the events route. If you want notifications of new messages, which is what you asked about, then listen to the WebSocket, which is what ChatExchange does. For listening for new messages, you're much better off using ChatExchange, which does the heavy lifting for you wrt. SE chat.

user435118

@Makyen I would prefer to use ChatExchange but I don't know how to use it.

user435118

And importing ChatExchange doesn't work even when I've installed it.

double-beep

4:27 PM

@Daniil have you tried this way: github.com/thomas-daniels/SO-EditMonitor/blob/master/…

user435118

>>> from ChatExchange.chatexchange.client import Client
Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    from ChatExchange.chatexchange.client import Client
ModuleNotFoundError: No module named 'ChatExchange'

user435118

Requirement already satisfied: ChatExchange in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (0.0.3)

double-beep

from chatexchange.client import Client

user435118

That worked

user435118

So how do I get the contents of any new messages posted in a specific room, say here?

user435118

4:30 PM

e.g. it prints all new messages posted

double-beep

@Daniil wasn't the example in the file I linked you earlier enough?

NobodyNada

@Daniil I don’t have time to make a whole tutorial, but the ChatRoom class has the functionality you need

user435118

@double-beep It's not working.

NobodyNada

in order to make a ChatRoom you’ll need to make a Client and maybe another intermediate object or two

Just look at the constructors and see what you need to give them

user435118

>>> c = Client("stackoverflow.com")
>>> c.login("REDACTED", "REDACTED")
RESPONSE REDACTED
>>> room = c.get_room(ROOM)
>>> room.join()

user435118

4:42 PM

It didn't join.

NobodyNada

@Daniil any error? Also have you tried it outside of the REPL?

user435118

@NobodyNada No error. What's REPL?

NobodyNada

Interactive Python en.m.wikipedia.org/wiki/Read–eval–print_loop

Also you probably have to keep going with the example github.com/thomas-daniels/SO-EditMonitor/blob/master/…

user435118

Now I get this

user435118

chatexchange.browser.LoginError: failed to get acct` cookie from Stack Exchange OpenID, check credentials provided for accuracy`

user435118

4:54 PM

They are working

Makyen

@Daniil When first trying new credentials with SD, I often need to try many times prior to it starting to work. I'm not sure of the cause, but once it starts working (without any changes to SD's config file), it seems to keep going, even if re-loging in using credentials.

user435118

See, I just logged in with them (Daniil-SD).

user435118

@Makyen Ok, I'll do a loop.

NobodyNada

Sometimes, you get captcha’d, to fix that have to open the login page yourself

I usually just log in with my own SE account in a private window

Makyen

@Daniil I'd wait a substantial amount of time prior to retrying. In fact, if I was doing this, I'd spin up an SD instance which used those credentials, so that I know the code was working and the only issue was getting the credentials to work. Once the SD instance was able to log-in consistently using just the credentials (i.e. removing pickles/cookies.p), then I'd try my own code.

user435118

5:00 PM

I'm not using SD code at all.

user435118

Huh, no error but the user isn't showing in the user list.

NobodyNada

SD uses ChatExchange

@Daniil yeah, that might not happen until you either post a message or tell CE to listen (as opposed to just join), not sure

Daniil-SD

test

user435118

Oh wow.

user435118

Can't believe that worked.

NobodyNada

5:02 PM

If you’re going to do that a bunch, maybe do it in a test room?

user435118

@NobodyNada I'm not but if I do I will.

Makyen

@Daniil Yes, but you're having problems which may be your code and may be the credentials. You have an SD instance. Spinning one up splits the problem into two things, both of which are more easily managed. That's a basic methodology for problem solving.

user435118

How can I make a continuous web socket? i.e. it listens and then the script stops after 5 seconds or so.

Mast

In which language, Python?

websockets

NobodyNada

@Daniil The CE listen method is async, you need to keep the script running somehow

user435118

5:07 PM

@NobodyNada Ok

user435118

It works, not as intended but still.

NobodyNada

How do you get events?

user435118

5:08 PM

from chatexchange.client import Client
from chatexchange.events import MessagePosted

def on_event(event, _):
    if not isinstance(event, MessagePosted):
        return
    msg = event.message.content_source
    print(msg)

c = Client("stackexchange.com")
c.login("REDACTED", "REDACTED")
room = c.get_room(11540)
room.join()

while True:
    room.watch_socket(on_event)

Mast

Oh, that's going to trigger an awful lot, isn't it?

user435118

Yeah, need to think of how to keep it running.

NobodyNada

@Daniil ... you’re spawning an infinite number of socket watchers

Makyen

@Daniil, I'm sure people are interested in helping you, but you need to take this to a different room, as it's really not about SD/MS/Charcoal (at this point). Which room would you like me to move this conversation to?

@Daniil Basically, this has turned into a help/debug session, which has grown beyond what should be in this room when it's for your own project. A quick question is fine, but it's now dominating the transcript, which isn't OK.

user435118

@Makyen Sorry.

user435118

5:14 PM

A room for using XneroBot (a bot which automates some flagging...

Makyen

@Daniil np. That doesn't mean that people don't want to help, just that we shouldn't impose on all the other people who are only interested in Charcoal related things. Thanks.

user435118

@NobodyNada Yeah, I am. How can I keep the script running without doing that?

NobodyNada

@Daniil well, that depends on when you want your bot to shut down

Mast

Keep it running just like the SD instances keep themselves running.

Time-out after X hours for reboot.

user435118

← 75 messages moved from Charcoal HQ

user435118

5:19 PM

@NobodyNada I can just kill the script manually. I just want the bot/script to be running until I shut it down.

user435118

So what I want is for it to print every new message in a specific room, but not 1000 times, only once and for it to be running until I kill it.

NobodyNada

Just sleep forever then

user435118

What do you mean?

NobodyNada

or like Mast suggested, if you’re running with something like nocrash.py sleep for 8 hours or so for an auto reboot

user435118

test1

user435118

5:24 PM

test2

user435118

test3

user435118

@NobodyNada Ah, it works. Sounds good. Thanks.

A: How to run the Python program forever?

How about this one? import signal signal.pause() This will let your program sleep until it receives a signal from some other process (or itself, in another thread), letting it know it is time to do something.

user435118

@NobodyNada Thanks.

user435118

Thanks, everyone for the help and sorry again about the offtopic discussion. cc @NobodyNada @Mast @Makyen @double-beep @thesecretmaster @user12986714

Makyen

5:44 PM

@Daniil np. It's not a big deal. Such things happen. What one thinks is an easy/quick question can easily grow to being something more significant. The important thing is being able to recognize when that's happened, that the conversation is off-topic for the original room, and change to a more appropriate venue, as was done here. Thanks for being willing to do so.
