emit - emit a generic event — fish-shell 4.8.1 documentation

# emit - emit a generic event

## Synopsis

    emit EVENT_NAME [ARGUMENTS ...]

## Description

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

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

## Example

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

## Notes

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.
