        super().__init__('my_plugin', 'metrics', 'My Metrics')
    
    def extract_data(self, node=None, **kwargs):
        return {'value': 42}

def auto_load(config=None):
    register_display_provider(MyDisplay())
    return True

🎓 Key Concepts

What is a DisplayProvider?

A Python class that:
- Extracts data from your plugin/node
- Formats it for display (JSON, HTML, text, etc.)
- Registers itself with the global DisplayRegistry
- Gets auto-discovered by web_user and tui

How Do Users Access It?

Via web_user (HTTP):

curl http://localhost:8765/api/display/render/plugin:section

Via tui (BIOS console):

bios> 7   # if your section is #7

What Do I Need to Implement?

Minimum (3 methods):

def __init__(self):                    # Set plugin_name, section_id
def extract_data(self, node, **kwargs):  # Return dict with data
def auto_load(config):                 # Register the provider

Optional (for custom formatting):

def format_html(self, data):           # Custom HTML output
def format_text(self, data):           # Custom text output
def format_table(self, data):          # Custom table output

❓ Common Questions

Q: How do I create a display provider?

A: See DISPLAY_API_QUICKSTART.md or example_display_plugin.py

Q: Where do I register my provider?

A: In your plugin's auto_load() function:

def auto_load(config=None):
    register_display_provider(MyDisplay())
    return True

Q: Will it break existing code?

A: No! 100% backward compatible. All built-in sections still work.

Q: What formats are supported?

A: JSON, HTML, TEXT, TABLE, TREE. Defaults provided for all.

Q: Can I access it without web_user or tui?

A: Yes, use the registry directly:

from opensynaptic.services.display_api import render_section, DisplayFormat
output = render_section('plugin:section', DisplayFormat.JSON)

Q: How do I test my provider?

A: See DISPLAY_API_GUIDE.md Testing section

🔧 Integration Checklist

For each plugin wanting to add custom displays:

• Read DISPLAY_API_QUICKSTART.md
• Review example_display_plugin.py
• Create DisplayProvider subclass(es)
• Implement extract_data()
• Add custom format methods if needed
• Call register_display_provider() in auto_load()
• Test via web_user: curl http://localhost:8765/api/display/providers
• Test via tui: press '[m]' to see all providers
• Update documentation/comments
