Re: [PD] [list length] counts unusual
Hmm, I think the design is, in fact, wrong. But should I now fix it (incompatibly)? drat.

Hallo, Miller Puckette hat gesagt: // Miller Puckette wrote: Hmm, I think the design is, in fact, wrong. But should I now fix it (incompatibly)? drat. I think you should. I don't think many people have used the length operation of [list] so far, as 0.40 still is quite new and there isn't a pd-extended version of 0.40, so I'd guess it's not widely in use yet. In fact, only those users, who explicitly wanted to count *without* meta-selectors will have to adapt their patches and I guess the number of users who wanted this is even smaller. So now's the time for change! ;) Ciao -- Frank Barknecht _ __footils.org_ __goto10.org__ ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

You don't need to play with it much, it's a decision to make: Do you want to have [list length] give the same length for 1 2 3 and a b c and list a b c or should a b c be one less?

[PD] [list length] counts unusual
Hi, I just found out that the new [list length] from Pd-0.40 counts the length of messages slightly unusual. Counting the elements in a meta-message like walk the dog will leave out the first element, walk in the example, and give a result of 2. The proper list message list walk the dog however will count as 3. This gets even more confusing with the other example in the list-help.pd file: 1 x y has a list-length of 3, however x 1 y only has a list-length of 2. And it gets quite nasty with an argument-less meta-message like set, which has a list-length of 0 just like the real empty list: a bang-message. I can see the logic behind this (counting only the arguments to a message but not the selector). But as all other [list] objects besides [list trim] automatically convert incoming meta-messages to list-messages I think I would expect the same to happen for [list length].

I consider this to be a bug in pd. In the meanwhile, use a dummy [list] before every use of [list length] in order to force a cast. _ _ __ ___ _ _ _ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
