\section emit emit - Emit a generic event

\subsection emit-synopsis Synopsis
\fish{synopsis}
emit EVENT_NAME [ARGUMENTS...]
\endfish

\subsection emit-description 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.


\subsection emit-example Example

The following code first defines an event handler for the generic event named 'test_event', and then emits an event of that type.

\fish
function event_test --on-event test_event
    echo event test: $argv
end

emit test_event something
\endfish


\subsection emit-notes 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.
Add a 'generic' type of event that can be emited from any piece of code or by the user. Use this event layer to perform interactive configuration startup at the correct time. darcs-hash:20070819164230-75c98-f91b8a73de7bbbb500d80770ddf4d2d46ae592cc.gz 2007-08-19 16:42:30 +00:00			`\section emit emit - Emit a generic event`
