Can I add a status message from pipeline ?

[dridk]

Hi,

With pipeline, Is it it possible to display a status message when computing something ?

I think it is possible from Function using await __event_emitter_ç. But I have no idea how to call it.

I guess it should be inside the pipe() method.

Looking for the same. I can see this in one of my plugins:

                    await __event_emitter__(
                        {
                            "type": "status",
                            "data": {
                                "description": f"Added memory: {memories}",
                                "done": True,
                            },
                        }
                    )

And it does show up in the status. Are the event types/bodies were documented anywhere?

[joestump]

@dridk found these docs:

• https://docs.openwebui.com/features/plugin/functions/#event-emitters
• https://docs.openwebui.com/features/plugin/tools/#event-emitters

[joestump]

It would be nice per @dridk's recommendation to be able to emit the kind of "progress updates" you see in other LLM interfaces – e.g. "Crunching the numbers..." from a pipeline doing math. It looks like currently you can update "status" or append to the body of the chat.

[joestump]

Okay, I've figured this out and I now have my auto-memory function showing updates like OpenAI does. Here's an updated auto-memory function that shows a spinner as it digests the user input looking for new memories, shows the memories, and then finishes the status update.

The key is the boolean value you give to done. False means "keep the spinner spinning" while True will remove the spinner and present a final status. You can return "description": "" and it will remove the status entirely. If you do not send a "done": True then the last message will remain with the spinner spinning.

OK, but your example is a filter and not a pipeline. How can I publish an event status from a pipeline?

[PlebeiusGaragicus]

Yes - thank you for asking this. I am very much trying to also figure this out.

I have recently stumbled on this example but haven't finished looking it over enough.
