RJ_SCENE_SAVE prepare message

[danomatika]

I have an abstraction that uses a table to store sequences that I'm saving and loading via [u_dispatch] objects. I ran into an issue where I need to know when the state is being saved but before the actual "save" message is sent out in order to dump the contents of the table into [u_dispatch]. Otherwise, it's too late to dump the table by the time the "save" message is received.

I'd like to propose adding a "prepare" message to RJ_SCENE_SAVE and sending out just before sending the "save" message. I'm doing the following and the is working well:

[ prepare, save <
|
[ s RJ_SCENE_SAVE ]

Hi,

hm, I'm not (yet) convinced that it would be necessary to do any
changes to u_dispatch/u_loader/u_sssad. Maybe it's indeed better solved
outside as you seem to have done?

You already can send "prepare" to RJ_SCENE_SAVE if you like. Just listen
on RJ_SCENE_SAVE, route out "prepare" to do any preparations like
dumping the table. Then send "save" after "prepare".

Or maybe I don't understand how you propose to add the "prepare" message ...

All the best

Frank

Right. No changes are directly necessary. I'm proposing that a "prepare" message be added to the documentation as this is a general problem that is applicable beyond my set of rjlib compatible abstractions.

Hi,

I see. That's a good idea. I'll write something up to add to
u_loader-help.pd - or do you already have something?

Ciao
