```
## Implementation with Gradio
Gradio is an ideal choice for implementing this interface due to its simplicity, Python integration, and native support on Hugging Face Spaces.
### Core Components
1. **Chat Interface**:
```python
with gr.Blocks() as demo:
chatbot = gr.Chatbot()
msg = gr.Textbox(label="Message")
clear = gr.Button("Clear")
def respond(message, chat_history):
# RAG processing logic here
bot_message = get_rag_response(message)
chat_history.append((message, bot_message))
return "", chat_history
msg.submit(respond, [msg, chatbot], [msg, chatbot])
clear.click(lambda: None, None, chatbot, queue=False)
```
2. **Document Upload**:
```python
with gr.Tab("Upload Documents"):
file_output = gr.File()
upload_button = gr.UploadButton("Click to Upload a File", file_types=["pdf", "docx", "txt"])
def upload_file(file):
# Document processing logic here
process_document(file.name)
return file.name
upload_button.upload(upload_file, upload_button, file_output)
```
3. **Embedding Code Generation**:
```python
with gr.Tab("Embed"):
iframe_code = gr.Textbox(label="iFrame Embed Code")
js_code = gr.Textbox(label="JavaScript Widget Code")
def generate_embed_code():
iframe = f'<iframe src="{SPACE_URL}" width="100%" height="500px"></iframe>'
js = f'<script src="{SPACE_URL}/widget.js"></script>'
return iframe, js
embed_button = gr.Button("Generate Embed Code")
embed_button.click(generate_embed_code, None, [iframe_code, js_code])
```
## Norwegian Language Support
1. **Interface Localization**:
- Implement language switching functionality
- Store UI text in language-specific dictionaries
- Apply translations based on selected language
2. **Input Processing**:
- Handle Norwegian special characters correctly
- Implement Norwegian-specific text normalization
3. **Response Generation**:
- Ensure proper formatting of Norwegian text
- Handle Norwegian grammar and syntax correctly
## Responsive Design
1. **CSS Customization**:
```python
with gr.Blocks(css="""
@media (max-width: 600px) {
.container { padding: 5px; }
.input-box { font-size: 14px; }
}
""") as demo:
# Interface components
```
2. **Layout Adaptation**:
- Use flexible layouts that adapt to screen size
- Implement collapsible sections for mobile view
- Ensure touch-friendly UI elements
## Deployment on Hugging Face Spaces
1. **Space Configuration**:
- Create a `requirements.txt` file with all dependencies
- Set up appropriate environment variables
- Configure resource allocation
2. **Continuous Integration**:
- Set up GitHub repository for the project
- Configure automatic deployment to Hugging Face Spaces
- Implement version control for the interface
3. **Monitoring and Analytics**:
- Add usage tracking
- Implement error logging
- Set up performance monitoring
## Next Steps
1. Implement the basic chat interface with Gradio
2. Add document upload and processing functionality
3. Create embedding code generation feature
4. Implement responsive design and language switching
5. Deploy to Hugging Face Spaces for testing
6. Gather feedback and iterate on the design
