EMIT(1)

NAME
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 <#event>. 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.
