Usage Examples

See FEATURES.md for detailed usage examples for each feature.

Quick example:

from core.plugin_api import PluginAPI

api = PluginAPI()

# Load and use features
from plugins.auto_updater import AutoUpdaterPlugin
from plugins.stats_dashboard import StatsDashboardPlugin

updater = api.load_plugin(AutoUpdaterPlugin)
stats = api.load_plugin(StatsDashboardPlugin)

api.start_all()

# Use the features
updater.check_for_updates()
stats.record_counter("app_launches", 1)

Notes

• All network-dependent features gracefully handle offline scenarios
• Features are fully self-contained and don't interfere with existing functionality
• The original test_plugin.py continues to work as before
• All plugins can be enabled/disabled independently
