A counter! How? Aargh

1

I can’t believe I can’t figure this out :frowning: or even find the answer in the docs or on the forum…

All I want is a simple function (routine?) that counts from 0 to 7, incrementing each time it is called.

2

something like this?

(
~rout = Routine({
    inf.do({|i|
        (i.mod(7)).yield;
    })
});
)

~rout.next
3

Thanks. Honestly, I’ve been reading the helpfile on Routine for about two hours now, it still makes no sense to me whatsoever! But, thanks, that’s it. Except mod(8) is what I meant.

And… hmm. Why does it always start from 3?

Two other similar approaches that don’t use routines.

~counter = (
   current_value: 0,
   get_next: { |self|
        self.current_value = self.current_value + 1;
		self.current_value
   }
);

~counter.get_next().mod(8)




~count_globally = {
	~count_globally_n = ~count_globally_n ? 0; 
	~count_globally_n = ~count_globally_n + 1;
	~count_globally_n
};

~count_globally.().mod(8)

a = Pseq((0..7),inf).asStream; // could also be 1 repeat, of course
a.next;

Thanks both. And… I can’t believe I didn’t think of the Pseq solution!

Or:

a = Pn(Pseries(0, 1, 8), inf).asStream;
