emit - emit a generic event

emit EVENT_NAME [ARGUMENTS ...]

emit emits, or fires, an event. Events are delivered to, or caught by, special functions called event handlers <#event>. The arguments are passed to the event handlers as function arguments.

The --help or -h option displays help about using this command.

The following code first defines an event handler for the generic event named 'test_event', and then emits an event of that type.

function event_test --on-event test_event

echo event test: $argv end emit test_event something


Note that events are only sent to the current fish process as there is no way to send events from one fish process to another.
