Tick step: AND offset:

Support, Help & Resources
1

Hey all, wondering about this…

tick :t1, offset: 1, step: 2 works in a loop :+1:t2: …*
#1,3,5,7

I tried generating some varieties using things like .each but it doesn’t seem to work as expected, similarly with my first dabble with tick_set which I tried as a workaround.

v1

tick, offset,steps
t1,1,1   #1,2,3,4
t2,2,2   #2,4,6,8
t3,3,3   #3,6,9,12
t4,4,4   #4,8,12,16

At first I thought the problem was how I was using them, but appears the issue is when using the two options combined.

step: The amount to tick up by. Default is 1.
offset: Offset to add to index returned. Useful when calling tick on lists, rings and vectors to offset the returned value. Default is 0.

Observations:

  • when initialising a tick (named or anonymous) it defaults to 0, unless step is used, then the first value is step-1 :-1:t2:
    (*this is why only the first use-case works, offset: 1, steps: 2, ∴ the desired offset (1) is the offset used (2-1)
live_loop :ticker do
  puts tick :a, step: 3   #2,5,8
  wait 1
end
  • when using offset as a single argument the initial value can be set :+1:t2::+1:t2:

puts tick :a, offset: 3 #3,4,5

  • when combining the two to try to step every n steps from offset x, this fails.

:question::bug:Is this a bug?
Or is tick not meant to be used like this?
Also any workarounds?

Finally is it possible to get at the previous value?
I know it’s a longshot but I remember reading about how times are managed using threads and get set… a bit like rand_back but for ticks…

Thanks!
