Hello,
Happy new year pd-list !
With pd-0.46-7, loadbang method was called only once when patcher loads. Now with 0.47-1, loadbang method are now called twice. Why loadbang method is called twice ?
As far as I understand, loadbang method could be called not only on patcher load (LB_LOAD), but also when closing an abstraction (LB_CLOSE) and before the object is connected to parent patcher (LB_INIT).
Many externals uses this loadbang method to initiate their state. This new behavior trig a lots of "wrong argument for loadbang method" error in pd console.
Is it a good practice to rely on loadbang call to initiate objects ? or should we avoid it and use [loadbang] object and/or make initialisation in object_new method ? -- do it yourself http://antoine.villeret.free.fr
Happy new year to you...
I don't get this behavior - can you send a sample patch?
thanks Miller

here is a sample code that demonstrate the issue : https://raw.githubusercontent.com/avilleret/helloworld/loadbang_issue/hellow...
When the object is created, loadbang method is called. Save the patch. Close it Reopen it, then the loadbang method is called twice (maybe one time at object loading and one more at patcher loadbang).

Oh, I see :)
the "loadbang" method is now called with a floating-point argument, so you can do this:
static void loadbang_loadbang(t_loadbang *x, t_floatarg action) { if (action == LB_LOAD) outlet_bang(x->x_obj.ob_outlet); }
and just get the one bang. This was done to allow "init" and "Close" bangs as well.

This explains the "wrong argument for loadbang method" but not why the method is called twice at patcher loading.

Does it not? Once for "init", once for "load".

I only get "1" aka LB_INIT, I didn't get the LB_LOAD ("0")

Odd... you're doing this, right:
class_addmethod(helloworld_class, (t_method) helloworld_loadbang, gensym("loadbang"), A_FLOAT, 0);
?
