The APL Orchard

4:26 PM

i did find a glitch. it was that z isn't asigned correctly. did fix it tho but i can't figure out how to edit message ¯_(ツ)_/¯

you might want to put it somewhere like GitHub gist

dzaima

you can only edit messages for 2 minutes after posting it

btw, don't use disp∘← but try disp⊢← (and initialize disp somewhere), @Adám said ∘← is due to a buggy behavior

4:41 PM

and why not make (2÷⍨≢n) a "constant" variable, afaik the size of the board doesn't change over the time @BrianBED

4:52 PM

@LdBeth OOooo true

@LdBeth how do i make a RIDE workspace that works with github? or do you mean just copy paste the code to a repo when i send it here?

@BrianBED I use github.com/Dyalog/link , you might want to update the one shipped with your Dyalog cause that could be an old version.

That would make a text based directory representation from workspace and then you can version control it with git

@LdBeth o actually, later i want to make the map scale when you go out of bounds, so making it a constant would be problematic. tho tbf i need to change it a lot later anyways.

well you would probably end up rewrite ALL of them as you updating it.

5:08 PM

@LdBeth wait wdym? was there a version of link that came with my dyalog install or do you mean i need to update dyalog? i just checked with ]version and it said i have link 2.0.6 and dyalog 18.0

oh wait i understand now nevermind

6:05 PM

@Adám thank you ill make sure to read everything and ask about stuff i dont get. this is so epic

6:27 PM

@BrianBED When you post multi-line code, put it in a separate message and press Ctrl+k before Enter.

7:07 PM

actually, i do have a question now

im trying to figure out how to formulate it though i thought i had it but i dont

7:18 PM

@thejonymyster You're trying to formulate the question or the APL expression?

well, the first one, regarding the second one :P

yea im not sure how to ask, but im gonna bang my head at it for a few more minutes

ok so, im havent read super far through many guides besides the tryapl notebooks

but im trying to figure out how to just like, reverse a list

except i dont want the answer, i want to know what intuitions / ideas i should be looking towards to find the answer

Are you aware of APLcart? (gives answer!)

that i am not :o

For such a simple concept as reversing a list, you should expect APL to have a primitive function.

thats a good resource though ty lol

yea i guess it just wasnt covered in the tutorials i read

or only briefly

the first thing i tried was like

(-1) ⊢/ which... now that i think about it, would never work obviously gfsdg

7:25 PM

You can also explore the language bar, to get an idea about what is built into the core language.

ah right

i forgot to do that, ty

@thejonymyster Actually not that far off from a couple of working solutions: ⋄ ⊃¯5,/'Hello' and ⋄ ⊃,⍨/'Hello'

TryAPL

@Adám
olleH
olleH

ehh id only say its not far because theyre both relatively short and use reduce haha

huh, (-1)⊢/ doesnt seem to be different from 1⊢/

wait, nvm i get why

Btw, you know you can write a negative literal number using high minus? ¯1

7:30 PM

i was expecting (-1)⊢/(1 2)(3 4) to give (2 1)(4 3) but i get why it would not do that

i do, but i currently have ⊢ on my clipboard

Do you not have a way to type APL in the browser?

im not used to the keyscan shortcuts yet

ill get around to it ^_^

Get a clickable in-browser language bar: abrudz.github.io/lb/apl

ooh ty

@Adám what is my "bookmarks bar"

What browser do you use?

7:33 PM

firefox

on windows if it makes a difference

Ctrl+Shift+B to toggle it on and off.

ahaa there it is

thank youu thats so cool

i love technology

You can also use Ctrl+b which has all your bookmarks, not just those on the "bar".
