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\_eventecho event test: $argvendemit 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.
