1. Workaround gradio's limitation that doesn't directly allow passing
data from Python -> JS (only indirectly, through components) - see create_dataholder_gradio
2. Update the chat HTML structure-wise and incrementally ("diff" mode) -
see js_chat_html_update
This significantly makes the updates more efficient (no redundant HTML
rendering) and additionally allows for stable components in the chat
in streaming mode (e.g. important for example when extensions add <audio> elements in the chat - e.g. alltalk_TTS).
Allow extensions to modify the output when in chat mode and bot replies are streamed. This is useful, for example, for extensions that need access to the bot replies while they are streamed (e.g. incremental/streaming TTS).

Hey @czuzu |
|
I gotta check the PR list more often, this is something I've needed for a while. Thank God textgen is open source and I can implement these changes on my own rig. Ty❤️❤️ |

Hello,
I've setup TGUI with the alltalk_tts extension locally, modified the setup to allow for passing LLM replies as they're being generated (stream mode) to the extension, and to subsequently do real-time TTS (aka "incremental" TTS).
PR for the extension is in the backlog too, streaming TTS is working as expected locally, this one is for the parts in TGUI I needed to adjust/extend to allow this to work smoothly.
Mainly, 2 changes were needed:
output_modifier_streamhandler for extensions (works only for chat-mode currently) as the enabler for streaming the LLM text to extensions(the rest are miscellaneous changes - adding a llama3 instruction template and a commented line to allow remotely debugging TGUI)
Let me know what you think and btw, nice project!
Thanks!
