Development & Testing

Running the Extension for Testing

To test the extension during development:

1. Quick Start: Press F5 or go to Run > Start Debugging
2. Manual Launch: Open Run and Debug panel (Ctrl+Shift+D), select "Run Extension", then click play
3. Extension Development Host: A new VSCode window will open with [Extension Development Host] in the title
4. Testing: In the Development Host window, you can:
   • Access your extension via Command Palette (Ctrl+Shift+P)
   • Test all functionality in real-time
   • Check the Extensions view
5. Debug Output: Console logs appear in the original window's Debug Console
6. Reloading: After code changes, press Ctrl+R (or Cmd+R on Mac) in the Development Host to reload

Make sure your .vscode/launch.json file is properly configured (automatically created with the Extension template).

Performance Considerations

• Fuzzy search is optimized with debouncing
• Efficient file filtering system
• Handles workspace changes well

Known Issues

• Very large files/code-bases may impact performance
