Examples

// Center an element on the screen
position_x = background_width / 2 - element_width / 2
position_y = background_height / 2 - element_height / 2

// Check if application has focus
if is_origin_focused (
  log "Origin has focus"
)

// Display current application
log "Current application: " ++ focused_application + " (ID: " ++ focused_application_id ++ ")"

// Display battery information
if battery_charging (
  log "Battery: " + battery_percent ++ "% (Charging, " + formatTime(battery_time_until_full) ++ " until full)"
) else (
  log "Battery: " + battery_percent ++ "% (" + formatTime(battery_time_until_empty) ++ " remaining)"
)

// Helper function to format time in seconds to a readable format
def formatTime(seconds) (
  if seconds == null (
    return "Unknown"
  )
  
  hours = floor(seconds / 3600)
  minutes = floor((seconds % 3600) / 60)
  
  if hours > 0 (
    return hours ++ "h " ++ minutes ++ "m"
  ) else (
    return minutes ++ "m"
  )
)

// Responsive layout based on device type
if on_mobile (
  // Use mobile-friendly layout
  element_width = background_width * 0.9
) else (
  // Use desktop layout
  element_width = background_width * 0.6
)
