This documents an old version of fish. See the latest release.

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.

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.
