Hi all,
Does anyone find a way to test if an argument is void into an abstraction ? The default behavior is to consider it as a float "0", but it would be very helpful to distinguish a "0" and no argument.
Thanks.

If you don't mind using externals, you can use [iemguts/canvasargs] or [else/args]. I can't think of a way of doing this in Vanilla though. As you say, no argument seems to be indistinguishable from 0. ________________________________ From: Pd-list pd-list-bounces@lists.iem.at on behalf of abel.jerome@free.fr abel.jerome@free.fr Sent: 09 April 2018 13:02 To: pd-list@lists.iem.at Subject: [PD] Test if an argument is void

for a given argument, it's possible. e.g.: (it's also possible to count the number of arguments, but more complicated)

(the code has to be copied verbatim into your abstraction and cannot be wrapped into a helper-abstraction)

Nice! I definitely wouldn't have thought of this. ________________________________ From: Pd-list pd-list-bounces@lists.iem.at on behalf of IOhannes m zmoelnig zmoelnig@iem.at Sent: 09 April 2018 15:19 To: pd-list@lists.iem.at Subject: Re: [PD] Test if an argument is void
