===========================

Synopsis
|
|
--------
|
|
|
|
.. synopsis::
|

|
|
emit EVENT_NAME [ARGUMENTS ...]
|
|
|
|
Description
|
|
-----------
|
|
|
|
``emit`` emits, or fires, an event. Events are delivered to, or caught by, special functions called :ref:`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.
