Hi all, although i haven't really followed the thread in detail, i'd like to throw in that there's an external called [absattr] in the grill part of the PD cvs which implements attributes for abstractions. It's another spin-off from vibrez development and i think it's quite useful. There is an example included.
best greetings, Thomas

I don't entirely get how it works, looking at the help patch. What are the "attributes"?
Attributes are specific to Flext/Pyext, although GridFlow has a variant on this concept. It's not used in Pd. It's like what's called Keyword Arguments in several languages like Python and CommonLisp, and it's like the dash options in Tcl (though in Tcl it's not a language feature, just a convention).
Is [patcherargs 10 20] like this: [float $1] [float $2]?
I guess so, except that $1 defaults to 10, instead of defaulting to 0, or worse, instead that whenever $1 is 0, it gets replaced by 10...
[patcherargs] seems to allow any number of arguments in the parent patch and so can be used to support varargs abstractions, something that plain Pd can't because you can't even know how many args you really have.
Plus, [patcherargs] gives it as a list, which is then easy to process using [list] (and that's something that Frank will love).
It seems to be a black box, which I am not a fan of. I think we can do it cleaner and do it mostly in Pd.
I'm trying to say that Pd is broken and that [patcherargs] is cleaner...
It wouldn't need to have the "attributes" part available, so you could drop the second outlet and then it would be a very small and simple external whose code fits on a page. Of course I think it should be internal.
