@Adám the IO might've been the problem, the version ^ is for IO 1. I'm still taking the constant coefficient on the left,and not on the right, but mine is not wrong. Some minor modifications and it should work for polys in the order you specified

@Adám APLcart entry for ⎕TS redirects to ⎕TC: aplcart.info/?q=current%20time#

Try it online! how do i shorten this?

is there a short way to get dates as hh:mm::ss?

@Razetime Link to challenge?

1∘↓∘⍕¨ → 1↓¨⍕¨

Also I think one conversion into base 4 should suffice

Change 4 4 to single 4 if it's allowed to omit the first line entirely if all digits are small

@Bubbler that;s great

Try it online!

now at 45

@Bubbler Seems to work for the test cases

It does work for the test cases but try something like 01:02:01

It says Two lines with represent the BCD binary clock so I think 4 4 should be correct

Agreed

thankfully it's got that line

@Razetime Also you don't need to do number→string→number

@RGS no, i was replying to an unrelated message of yours

@Bubbler ah I never thought of that

just kept thinking "how do I pad this?!"

and actually 0 10⊤ works there in place of 10 10⊤

@Razetime ^

@Bubbler I'll change that

How do I convert a date array (mmddyyyy) to a single number?

I've only use 1⎕DT to convert years before

@Razetime Example?

12 01 2002 → ???

What's your expected result?

Also is it a 3-item vector of numbers?

I know that date number mod 7 is the day number(monday, tuesday, wednesday)

@Bubbler yep

@Bubbler a single number

a single long number

If any single number works, what about 1e4⊥?

basically i need a ⎕DT mode

not sure what does it

@Razetime Fixed.

found it i think

found a use case for dfns.easter

@Razetime ⋄ 1⎕DT⊂⌽12 01 2002

Hey, where's the bot?

@DyalogAPL where you at?

⋄ 1⎕DT⊂⌽12 01 2002

Bot is there, but apparently not responding

@Moonchild ^

⎕DT doesn't work on tio, does it work here?

Yes, it should. It came with 18.0, so try it locally.

oh nice

@Razetime 'hh:mm::ss'(1200⌶)ddn where ddn is e.g. 1⎕DT⊂⎕TS

I so hope we'll fold 1200⌶ into ⎕DT so one can do 'hh:mm::ss'⎕DT⊂⎕TS

that would be cool

There were intentionally designed to be combinable. The only reason we didn't combine them was because our chief architect thinks that formatting date-times belongs with all other formatting in ⎕FMT and not as part of the ⎕DT conversion.

@Adám But just a very small portion of date processing is formatting. Where do you put the calls to do calendar computations?

@EliasMårtenson Those are in ⎕DT

repl.it doesn't support uploading files for ngn/APL, are there any similar things that would support an APL dialect so I could easily give code to my teacher to run?

i mean, there's tio I suppose

or you can use the ngn/apl codebase to run stuff on repl.it

yeah, but as far as I can tell I can't then upload the file I need for the task

huh lemme try

@rak1507 repl.it/join/gaskcejd-razetime fork this

you can upload what you need

the upload menu is next to the add folder icon

Oh cool, did you write those programs?

no, those are ngn's examples

Makes sense, thanks

run using node apl.js <filepath>

I just made a programs folder for testing

note that you need ⎕← to display anything at all

yeah

kay cool have fun
