Features

• Interactive map of all 97 LotusScript classes, with 1,001 properties, 997 methods, and 72 events
• Click any property or method to see its full description, parameters, return value, and links to the HCL documentation
• Search filters both the sidebar list and highlights matching nodes on the canvas simultaneously
• Filter by type — All, UI classes, Backend classes, or classes with Events
• Hover a node to highlight its direct neighbours and connections, dimming everything else
• Hover a link to reveal the method or property name that creates the relationship (visible above 60% zoom)
• Auto-saves layout — drag nodes to arrange your workspace; positions are saved automatically to localStorage and restored on next visit
• Reset Layout returns to the default hub-and-spoke arrangement

Browser Support

Recommended: Chrome or Firefox.

Safari is not supported due to WebKit bug #23113, which affects how foreignObject elements render scrollable HTML content inside SVGs. This is a long-standing WebKit limitation unrelated to this application or JointJS.

Running Locally

The app is entirely client-side. Serve it from any static web server — it cannot be opened directly as a file:// URL because it fetches data/ls_classes.json via fetch().

Using Python:

python3 -m http.server 8080
# then open http://localhost:8080

Using Node.js:

npx serve .
