Event

The window object provides an event system for responding to various actions in your application:

// Basic event registration
window.on("event_name", def() -> (
  log "Event handler executed"
))

// Emitting custom events
window.emit("event_name")

Event Registration

Register event handlers using window.on():

window.on("paste", def() -> (
  log "Content was pasted"
))

Standard Events

• paste - Fires when any data is pasted

• copy - Fires when any data is copied to the clipboard

• system_focus_changed - Fires whenever the system's tab changes focus

• frame_end - Executes after the main code runs each frame, useful for cleanup or post-processing

Custom Events

You can create and trigger your own events:

// Register custom event handler
window.on("my_custom_event", def() -> (
  log "Custom event triggered"
))

// Later, trigger the event
window.emit("my_custom_event")

Important Notes

• Event names are case-sensitive

• Multiple handlers can be registered for the same event

• Handlers execute in the order they were registered

• Custom events are useful for decoupling application components

• The window.emit() method can be used to manually trigger any event
