🚀 Quick Start (3 Steps)

Step 1: Read Quick Start (5 min)

cat DISPLAY_API_QUICKSTART.md

Step 2: See Examples (10 min)

cat src/opensynaptic/services/example_display_plugin.py

Step 3: Create Your Provider (15 min)

from opensynaptic.services.display_api import DisplayProvider, register_display_provider

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

✨ What Changed

Before (Hardcoded)

# In tui/main.py - must modify core code
def _section_custom(self):
    return {'metric': get_value()}

_SECTION_METHODS = {'custom': '_section_custom'}

After (Plugin-Based)

# In any plugin - no core changes needed
class CustomDisplay(DisplayProvider):
    def extract_data(self, node=None, **kwargs):
        return {'metric': get_value()}

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

💻 How to Use

Access via web_user

# List all providers
curl http://localhost:8765/api/display/providers

# Render specific section
curl http://localhost:8765/api/display/render/plugin:section?format=json

# Get all sections
curl http://localhost:8765/api/display/all?format=html

Access via tui

python -u src/main.py tui interactive

bios> m              # Show provider metadata
bios> s metrics      # Search sections
bios> 7              # Switch to section 7
bios> j              # View as JSON
