const compilerPath = "path/to/ygscript.exe"; // or .sh on Unix

Editor Settings

In VS Code settings.json:

{
  "editor.defaultFormatter": "YGStudio.ygscript",
  "[ygscript]": {
    "editor.tabSize": 2,
    "editor.insertSpaces": true,
    "editor.formatOnSave": true
  }
}

File Icons

The extension provides:

• .yg file icon - Custom YGScript icon with distinctive styling
• Theme support - Works with both light and dark VS Code themes
• Explorer integration - Icons appear in the file tree

Error Checking

Real-time error detection shows:

• Syntax Errors - Tokenization failures
• Parse Errors - Grammar violations
• Type Errors - Type mismatches (when available)

Errors are displayed with:

• Line and column numbers
• Error message
• Red underline in the editor

Troubleshooting

Extension not activating

• Check that you have .yg files open
• Verify the file language is set to "YGScript"
• Restart VS Code

Run command not working

• Ensure YGScript compiler is installed
• Check the compiler path in extension.js
• Verify the .yg file is saved (or use Ctrl+S)

Icons not showing

• Reload VS Code window (Ctrl+Shift+P → Reload Window)
• Check VS Code version is 1.74.0 or newer

Error checking too slow

• Increase debounce timeout in extension.js (default: 800ms)
• Use simpler files for testing
