Watch Mode

Both build and run commands support watch mode for development:
  • Build watch: Automatically recompiles when source files change
  • Run watch: Automatically restarts the application when files change
Watch mode is perfect for:
  • Plugin development
  • Server module development
  • Rapid prototyping
  • Testing changes in real-time
# Development workflow
mcmp build --watch    # Terminal 1: Auto-compile
mcmp run --watch      # Terminal 2: Auto-restart
