That's because it's only based on functions that are already in GridFlow, and there is no such random() in GridFlow. I already fudged quite a few things in [#expr] though, so I might be able to fudge this one. At this point, the only ops I can import directly into [#expr] are the ones that already exist in [#]. Maybe it's just easier to add 'random' to [#].
I noticed that [#expr] (i.e., with no args) doesn't
create.
With the current grammar used by [#expr], empty expression doesn't parse. So I just set the expression "0" as the default args of [expr] when there are no args at all.
If I do [#expr max(1,3)] and send a float to the inlet
it crashes Pd. (Same with other functions)
[#expr] without any $f1-style variables has an empty 'inputs' array but try to assign to inputs[0] anyway.
What are rem, cmp
'rem' is [expr $f1 % $f2] 'cmp' is [expr $f1<0 ? -1 : $f1>$f2]
c2p and p2c?
They never were in. It was a mistake. Those are 'vecops', which means that each of them take as inputs two pairs of numbers and output one pair. But [#expr] doesn't support grids yet, so, it didn't make any sense whatsoever to include them at this point.
Seems like this is a bigger problem, because most of
the time when I use send/receive, IEMGUIs, or [value] in an [expr]-less context I am also using $0-foo as the most common case.
It sounds like "$0-" would make a good default prefix, then, especially with the number of people using it (though a few people use different conventions).
So I think your reasoning for not wanting $0 "in your
face" in a complex formula also extends quite naturally to Pd in general. Anytime I use [s $0-a] I'd rather write [s a] and have it be local by default.
Yeah, but the way Pd is made, it's too late, we can't change this, or we have to change pd_bind and all the externals that use receive-symbols.
Then the only way out is to make individual solutions whenever "$0-" gets too annoying. For example, [receives] allows you to write something like [r $0-a] [r $0-b] [r $0-c] as [receives $0- a b c] which outputs symbol a or symbol b or symbol c by the right-outlet just before outputting the received message by the left-outlet.
Thanks, I'll have a look at that.
I could be making more classes like that if you want.
