⏳ Remaining Steps

Step 1: Install Dependencies

cd ui/desktop
npm install

What this does:

• Installs @monaco-editor/react@^4.6.0
• Monaco Editor will be loaded from CDN at runtime
• No additional configuration needed

Step 2: Integrate Monaco into RichChatInput

Status: 📋 Ready to implement after npm install

File: ui/desktop/src/components/RichChatInput.tsx

Changes Needed:

A. Add imports (top of file, around line 7):

// ADD THIS:
import { lazy, Suspense } from 'react';
import MonacoCodeInput from './MonacoCodeInput';

// Lazy load Monaco for better performance
const MonacoCodeInputLazy = lazy(() => import('./MonacoCodeInput').then(m => ({ default: m.MonacoCodeInput })));

B. Replace SyntaxHighlighter in code mode rendering (around line 665-740):

Find this section:

{/* Code content with syntax highlighting - constrained to container width */}
<div 
  className="block font-mono text-sm bg-[#1E1E1E]/30 rounded p-2 border border-gray-700/50 mt-1 w-full overflow-x-auto relative"
  style={{ 
    fontFamily: 'Monaco, Menlo, "Ubuntu Mono", Consolas, source-code-pro, monospace',
    maxWidth: '100%',
    boxSizing: 'border-box',
  }}
>
  {cursorInCode ? (
    // ... SyntaxHighlighter code ...
  ) : (
    // ... SyntaxHighlighter code ...
  )}
</div>

Replace with:

{/* Monaco Editor for live code editing */}
<Suspense fallback={
  <div className="flex items-center justify-center h-32 bg-[#1E1E1E]/30 rounded border border-gray-700/50">
    <div className="animate-spin rounded-full h-8 w-8 border-t-2 border-b-2 border-blue-500" />
  </div>
}>
  <MonacoCodeInputLazy
    language={codeMode.language}
    value={codeContent}
    onChange={(newCode) => {
      // Update the full value with new code
      const beforeCode = value.slice(0, codeMode.startPos);
      const afterCode = value.slice(codeMode.startPos + codeContent.length);
      const newValue = beforeCode + newCode + afterCode;
      onChange(newValue, codeMode.startPos + newCode.length);
    }}
    onSend={() => {
      // Trigger send via parent's onKeyDown
      const syntheticEvent = new CustomEvent('submit', {
        detail: { value },
      }) as unknown as React.FormEvent;
      onKeyDown?.(syntheticEvent as any);
    }}
    onExit={() => {
      // Exit code mode
      setCodeMode(null);
    }}
    height="auto"
    theme="vs-dark"
    className="mt-1"
  />
</Suspense>

---

Step 3: Add CSS Styling

Status: 📋 Ready to implement

File: ui/desktop/src/styles/main.css

Add at the end:

/* Monaco Code Input Wrapper */
.monaco-code-input-wrapper {
  border-radius: 8px;
  border: 1px solid rgba(255, 255, 255, 0.1);
  overflow: hidden;
  background: #1E1E1E;
  margin-top: 8px;
}

/* Smooth transition when entering code mode */
.monaco-code-input-wrapper {
  animation: slideDown 0.2s ease-out;
}

@keyframes slideDown {
  from {
    opacity: 0;
    transform: translateY(-10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

/* Loading spinner */
.monaco-loading {
  display: flex;
  align-items: center;
  justify-center;
  min-height: 100px;
}

Step 4: Testing

Status: 📋 After implementation

Manual Testing Checklist:

• Start dev server: npm run start-gui
• Type #python in chat input
• Verify Monaco loads (may take ~500ms first time)
• Type code and verify syntax highlighting
• Test autocomplete (type def hel and wait)
• Test Enter key (should insert newline)
• Test Cmd+Enter (should send message)
• Test Escape key (should exit code mode)
• Test with different languages (javascript, typescript, etc.)
• Verify height adjusts correctly
• Check performance with large code blocks

Test Cases:

1. Basic activation: #python → Monaco appears
2. Syntax highlighting: Type code → Colors appear
3. Autocomplete: Type partial word → Suggestions appear
4. Multi-line: Press Enter → New line added
5. Send: Press Cmd+Enter → Message sent
6. Exit: Press Escape → Back to normal mode
7. Language switching: Try #javascript, #typescript, etc.

💡 Tips for Integration

If Monaco doesn't load:

• Check browser console for errors
• Verify network tab shows CDN requests
• Try clearing browser cache

If autocomplete doesn't work:

• Wait 1-2 seconds after typing
• Ensure language is supported
• Check Monaco loaded successfully

If height is wrong:

• Check calculatedHeight in MonacoCodeInput
• Verify min/max constraints
• Test with different code lengths

If keyboard shortcuts don't work:

• Verify onSend and onExit props are passed
• Check addCommand in handleEditorDidMount
• Test in browser dev tools
