Hi Frank, I understand what you describe. But when the 1st creation argument is a float, [list $1] and [list append $1] print the exact same result as far as I can see.
(Shaky comp sci terminology to follow...) Looking at list_new in x_list.c, if the first creation argument of [list $1 $2 etc.] is a not a symbol, the object is deemed a [list append] and the args are left alone. For [list append $1 $2 etc.] however, after "append" is matched, the argument count is decremented and the 2nd arg becomes the 1st. Consequently, the behavior of [list $1 $2 etc.] is exactly the same as [list append $1 $2 etc.] in this case. -Jonathan --- On Sun, 3/22/09, Frank Barknecht <f...@footils.org> wrote: > From: Frank Barknecht <f...@footils.org> > Subject: Re: [PD] ADSR variations [was: Re: Patch-off] > To: pd-list@iem.at > Date: Sunday, March 22, 2009, 12:27 PM > Hallo, > Jonathan Wilkes hat gesagt: // Jonathan Wilkes wrote: > > > Actually [list $1 $2 $3 $4 $5] seems to work in this > context, but I guess > > that's because the first arg isn't a symbol. > Is that why you're saying [list > > append] is needed? > > The [list] object will behave differently depending on its > first argument: You > get to choose between [list prepend], [list append], [list > split] etc. The > following arguments have different meanings depending on > the first argument. > > E.g.
