## TUI / Term
TODO: document Component and rendering related stuff
## Event
The `helix-event` crate defines primitives for defining and acting on events
within the editor. "Events" cover things like opening, changing and closing of
documents, starting and stopping of language servers and more.
`helix-event` has tools for defining events and registering _hooks_ which run
any time an event is emitted. `helix-event` also provides `AsyncHook` - a tool
for running cancellable tasks which run after events with _debouncing_.
See the `AsyncHook` type for more information. Events can be created within the
`events!` macro. Synchronous hooks can be created with `register_hook!`. And
editor-wide events can be sent to hooks with `helix_event::dispatch`.
