remove ChatManager

[theomonnom]

I think it is a good timing to do it for v1.0

[lukasIO]

makes sense to me, should we have a last 0.x release that deprecates it and offers alternatives?

[theomonnom]

we will release a major version, v1.0

Whats the alternative here guys? You pulled these api's, the docs are all outdated. Whats the alternative for this or have we reached a point where the community needs to fork?

Plus one, I wanted to update Livekit deps and now I don't know how to start it

    chat_manager: rtc.ChatManager,
                  ^^^^^^^^^^^^^^^
AttributeError: module 'livekit.rtc' has no attribute 'ChatManager'. Did you mean: 'E2EEManager'?

Happened when I did

# livekit-plugins-elevenlabs = "0.7.9" -> "0.8.11"
poetry update

poetry.lock diff

+    {file = "livekit-0.22.0.tar.gz", hash = "sha256:273fd75a164fb1be6745ddd624361fba86131be397e629597719f303f2c29730"},

I bet it is in many peoples code right now. Deleting it without explanation and message about deprecation is a mistake

[NameICanWrite]

I am going to just write the same code myself. The only possible alternative ...

So , what I have done - I just copied the code from the deleted rtc/chat.py to custom_chat_manager.py . And used it like this for agent to answer text messages for example. It worked

from custom_chat_manager import ChatManager, ChatMessage

def on_chat_message(message: ChatMessage):
            asyncio.create_task(livekit_service.pipeline_answer_from_text(agent, message.message))

        chat_manager = ChatManager(ctx.room)
        chat_manager.on("message_received", on_chat_message)
        
async def pipeline_answer_from_text(
    agent: VoicePipelineAgent,
    txt: str,
    role: Literal["user", "assistant", "system", "tool"] = "user",
):
    logger.info(f"Pipeline answer from text: {txt} with role: {role}")
    chat_ctx = agent.chat_ctx.copy()
    chat_ctx.append(role=role, text=txt)
    stream = agent.llm.chat(chat_ctx=chat_ctx)
    await agent.say(stream)

Sorry about that. We'll be releasing Agents 1.0 soon, which will offer a number of new features, including the ability to use text streaming for text input.

For anyone coming here like me also wondering why ChatManager was removed - CW graciously explained in slack that ChatManager was "mis-leading" and the wrong layer of abstraction, and it's better to just handle the data frames directly - appreciate the explaination!

apologies for the lack of explanation. we are in the middle of upgrading the whole text stack in LiveKit to TextStreams.

the frontend apps will be updated in the next week as well. instead of ChatManager, you could listen to a text stream of lk.chat and text = await reader.read_all() once the reader is received.

if this becomes an issue for you, please feel free to use an older version of livekit package for now.
