The APL Orchard

I can't see the leetcode question, it has a login prompt; maybe you could use grade to find the largest instead of max-reduce-iota?

some variation on 'abcde'[1+⊃(⍋2-/⊢)1 3 5 8 9]

like one without parens and right tack 'abcde'[⊃⍋2-/1 3 5 8 9]

@TessellatingHeckler simplified failing example - ≢⟨⟩⥊⟨1,2⟩

8:29 AM

@dzaima I think it was coming from the $() in case 10,19, and I rewrote it, which changed that one but doesn't change this one

@dzaima what should this do, an empty list reshape?

@TessellatingHeckler actually, it doesn't do what i meant it to, but it doesn't really matter here - all i was trying to get was getting the shape of a scalar

this is what i wanted to do - ≢⟨⟩⥊⟨⟨1,2⟩⟩; but it should act the same way

ok that is in the code for reshape where it also has a $() with an "if" inside it, and it returns $w instead of ,$w

 &$arr ($x[0..($x.Count-1)]) $(if($null-ne$w){,$w}else{,@($x.Length)})}

$() is also in divide and minus, presumably their arguments can only be scalar integers, and lesseq where the return value is only going to be 0 or 1 not an array

@TessellatingHeckler right, that's true

@TessellatingHeckler and with that runtime seems to finish executing..?

:O

oh yeah i also make call's last line be return ,(&$f $x $w);

8:42 AM

I tried that on $call and removed it a couple of times; it does seem to finish, and returns ... a single function?

@TessellatingHeckler seems to return a list of functions for me (with the different runtime)

end of execution:

@dzaima note the reduction of the stack size from 62 to 1 at the end - making a 62-item list

going to recompile the original new runtime and retry

@dzaima that's a lot more than I get from it

@dzaima dzaima.github.io/… using the runtime from ./cjs.bqn r

@dzaima could you paste your code so I can diff, please?

8:58 AM

@TessellatingHeckler with a fresh properly compiled runtime (at whatever commit i'm at): gist.github.com/dzaima/df3832a8bd87ad56093e9e64576a557a

@dzaima they seem very similar, and if I copy your bytecode in, I get a ton of functions out

array-manipulation

cool

changing $qq to $runtime and seeing if the compiler builds (nope)

Is that PHP?

@TessellatingHeckler so something's wrong with your runtime version. i think my new one is fine

@Azmuth nothing here is PHP

9:08 AM

Then what?

@Azmuth It's PowerShell, I've been trying to port Marshall's BQN interpreter in JavaScript into it

Oh okay!

So people only talk about Powershell here?

(as a stepping stone on the way to C#, maybe, although this was beyond me without help)

@Azmuth no, this is primarily an APL room, this is a powershell implementation of a language descended from APL

@Azmuth Gosh no, I'm the only one who is dragging that in. Here is for APL and array languages and array related discussions

and BQN is one of those languages

@Azmuth Do you know about APL?

> There’s one thing that comes through in a lot of this history, by the way: notation, like ordinary language, is a dramatic divider of people. I mean, there’s somehow a big division between those who read a particular notation and those who don’t. It ends up seeming rather mystical. ― Stephen Wolfram
