# 🦙 Panel ChatBot Pack
Build a chatbot to talk to your Github repository.
Powered by LlamaIndex, OpenAI ChatGPT and [HoloViz Panel](https://panel.holoviz.org/reference/chat/ChatInterface.html).
## 💁♀️ Explanation
This template
- Downloads and indexes a Github repository using the `llama_index` [`GithubRepositoryReader`](https://llamahub.ai/l/github_repo). The default repository is [holoviz/panel](https://github.com/holoviz/panel).
- Creates a [VectorStoreIndex](https://docs.llamaindex.ai/en/stable/changes/deprecated_terms.html#VectorStoreIndex) powered chat engine that will retrieve context from that data to respond to each user query.
- Creates a Panel [`ChatInterface`](https://panel.holoviz.org/reference/chat/ChatInterface.html) UI that will stream each answer from the chat engine.
## 🖥️ CLI Usage
You can download llamapacks directly using `llamaindex-cli`, which comes installed with the `llama-index` Python package:
```bash
pip install llama-index
llamaindex-cli download-llamapack PanelChatPack --download-dir ./panel_chat_pack
```
You can then inspect the files in the `panel_chat_pack` folder and use them as a template for your own project!
To run the app directly, use in your terminal:
```bash
export OPENAI_API_KEY="sk-..."
export GITHUB_TOKEN='...'
panel serve ./panel_chat_pack/base.py
```
As an alternative to `panel serve`, you can run
```bash
python ./panel_chat_pack/base.py
```

## 📈 Potential Improvements
- [ ] Improved Multi-user support
- [ ] Loading queue: Users should not be able to download the same repository at the same time.
- [ ] Service Context
- [ ] Enable users to define the service context including `model`, `temperature` etc.
- [ ] Better loading experience
- [ ] Let the chat assistant show (more fine-grained) status messages. And provide more status changes
- [ ] Focus on the streaming text
- [ ] The streaming text is not always in focus. I believe its a matter of adjusting the `auto_scroll_limit` limit.
- [ ] Fix minor CSS issues
- [ ] See the `CSS_FIXES_TO_BE_UPSTREAMED_TO_PANEL` variable in the code
- [ ] Repo Manager
- [ ] Support using multiple repos. For example the full HoloViz suite
