Hi,
Currently, there is no mechanism to support running command at a
specific event, such as, whenever a menu is selected, this makes it
difficult to implement functions like savedefault or password. I
sugguest the following model.
First, UI components register events, which is a subclass of named list:
struct grub_event
{
next;
name;
event_list;
};
It then fires the event at apropriate time:
grub_err_t grub_dispatch_event (struct grub_event *);
Also add a command "event" to let user assign action to a event,
something like this:
event list [event_name]
event insert event_name command [arguments]
event remove event_name command
With this, safedefault could be implemented as:
event insert menu_select save_env default
