@FawnLocke Your vocabulary site still has some ids and queries.

@Adám Hey, sorry, was away for some time. There's no need for my name in the credits, but thanks for asking
I'd love, however, to see it when it's ready

Live at dyalog.tv tomorrow at 16:00 UTC and available for viewing thereafter.
André Leria
André Leria
Which is in exactly 24 hours?
Adám
Adám
Yes.
André Leria
André Leria
Great, will do
I happened to read a bit more about ⍣ after we discussed that code. While I did ⍣2 so it would do the left-hand function twice, I could have done something like ⍣(>∘9≢), right?
So it'd stop evaluating once the size of the right-hand argument is greater than 9, twice
Is that it?
Adám
Adám
Almost. You'd need ⍣{9<≢⍺}
André Leria

Hmmm
Would ⍺ in this case refer to the result of the left-hand function?
Adám
Adám
Yes. And ⍵ would be the previous value.
So you could also write ⍣{9=≢⍵}
André Leria
André Leria
So I'm right about ⍣ stopping after the result of the right operand being non-zero twice?
Adám
Adám
No, it stops as soon as the right operand returns 1.
André Leria
André Leria
Hmmm, ok, so I still need to understand it better
Adám
Adám
It is basically "until".
André Leria

I see, that makes some more sense
And in this case, it'd be 10, not 9
I thought it was 9 due to the "twice" idea
(CPFs are always length 11)
I think the "clearest" way would be ⍣{11≤≢⍺} then?
Adám
Adám
Ah, yes, of course. But in this case ⍣2 makes more sense.
André Leria
André Leria
It does, since the algorithm always expects 9 digits as input
Any other number of digits should not silently work, it should be an error
Still, I believe in most applications, data would be sanitized before being passed to such a function

@Adám it seems like the contents are broken on the rank page aplwiki.com/wiki/Rank_(operator)
Adám
Adám
@FawnLocke What's broken?

The contents don't show for me
Oh, it's bugged on other pages too
André Leria
André Leria
It's fine to me
Adám
Adám
Fine to me too.
André Leria
André Leria
Perhaps it's an issue with your browser?

or some userscript/style?
Adám
Adám
No, wait, you're just on mobile view!
Does look borked on mobile view. I can't seem to be able to expand the Contents.

I'm using firefox on my laptop, no userscripts. I did recently clear my cache, cookies, etc
