emit - emit a generic event¶

Synopsis¶

emitEVENT_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.

functionevent_test--on-eventtest_event
echoeventtest:$argv
end
emittest_eventsomething

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.
