Reseting a routine from within itself

Questions
1

Hi! I need to have a routine that can embed a pattern and then embed another pattern when the previous pattern ends.

~pattern = Pseq([1, 2, 3, 4],1);
~pattern = Pseq([5, 6, 7, 8], 1);

(
r = Routine {
	~pattern.embedInStream;
	~pattern.embedInStream;	
};
)

r.next;

This “works” but it’s obviously not the greatest solution. I want to have the routine reset somehow when the pattern ends so that I can redefine the variable ~pattern when ever and have it embeded on time.

The only way i can find to reset a routine from within itself is the .yieldAndReturn method but as the name suggests it also yields something so it’s not very useful to me.

Ok i solved with this hacky function:

(
var next;
next=r.next;
if (next==nil, {r.reset.next}, {next});
)

Keeping the thread open though. More elegant solutions are welcome.

Yeah I’ve gone through that doc a few times. loop slipped by unnoticed somehow.
