Category: puredata Group: wishlist Status: Open Resolution: None Priority: 5 Private: No Submitted By: IOhannes m zmölnig (zmoelnig) Assigned to: Miller Puckette (millerpuckette) Summary: [initbang]/[closebang] for patch constructor/destuctor

Initial Comment: attached is a patch that adds a new object [initbang] to Pd.

This object is similar to [loadbang], however it gets executed just after the rest of the abstraction is built and _before_ the parent of the abstraction is finished.

reasoning: this object allows abstractions to have a runtime constructor (similar to the <object>_new() constructor of c-externals); the [initbang] is emitted before the parent patch is finalized, thus allowing the abstraction to add inlets/outlets depending on its arguments).

caveats: a similar method for the abstraction _destructor_ is still missing.

i haven't implemented an "initbang" message to the canvas to rerun the initialization again.

This is huge, it allows Pd objects to dynamically generate inlets and outlets and have then work properly.

for reasoning why this is needed, see the pd-dev archives

the 2nd patch additionally implements a [closebang] object, which gets called just before a canvas is destroyed.

note that the patch (cloeinitbang.diff) holds both the closebang- and the initbang-changes; do not! apply both patches
