/// See `:help autocmd-events` for a list of supported event names. Event names can be

/// the callback function; so always use the `args` mechanism instead.
///
/// - `cb`: The callback function.
/// This will be called each time the event triggers or when `run_now` is called.
/// It is passed a vector with the results of the evaluated expressions given with `args`.
///
/// # Example
///
/// Call a function each time a buffer is entered or the current working directory is changed.
/// Pass the current buffer name and directory to the callback.
/// ```
