Events

The call Tezos.emit(event_tag, event_type) evaluates in an operation that will write an event into the transaction receipt after the successful execution of this contract. The event is annotated by the string event_tag if it is not empty. The argument event_type is used only to specify the type of data attachment.

To actually emit an event, this operation must be returned the same way as other operations, like an origination or a transfer.

The first string argument must use the following notation:

  • "%bar" is expected for entrypoint "Bar"
  • "%default" when no entrypoint is used.
  • Valid characters in annotation: ('a'..'z' | 'A'..'Z' | '_' | '.' | '%' | '@' | '0'..'9').
