Enhanced Visual WIT Interface Designer

[avrabe]

Overview

Create a comprehensive visual editor for WebAssembly Interface Types (WIT) that enables drag-and-drop interface design with real-time validation.

Current State

• We have excellent WitInterfaceRenderer for visualization
• Component palette supports basic drag-and-drop
• Missing: Direct editing of WIT interfaces in visual mode

Proposed Enhancements

Visual Interface Editor

• Drag-and-drop WIT element creation (interfaces, functions, types)
• Real-time syntax validation
• Auto-completion suggestions
• Visual property editing with inline editors
• Template library with pre-built patterns

Integration Points

• WitAnalyzer integration for real-time validation
• Export to .wit files with proper formatting
• Bidirectional sync between visual and text editing
• Component palette integration for seamless workflow

Technical Implementation

• Extend WitInterfaceRenderer with edit capabilities
• Add visual editing widgets to canvas
• Integrate with existing WitAnalyzer for validation
• Create template management system

Success Criteria

• Create complete WIT interfaces without text editor
• Real-time validation prevents syntax errors
• Export produces clean, properly formatted .wit files
• 10x faster interface design vs manual coding

Priority: High - Estimated effort: 3-4 weeks, 2 developers
