Q: CGAC2022 Day 3: \$n\$-dimensional Chocolate Pyramid

Part of Code Golf Advent Calendar 2022 event. See the linked meta post for details. I've got an infinite supply of \$n\$-dimensional chocolate for some positive integer \$n\$. The shape of the chocolate is not important. You may assume that they are just \$n\$-dimensional hypercubes with side le...

Q: Generate an image containing lots of random dots

Introduction I need a piece of code that is either fairly easily compliable to Windows .exe or fairly easy to be run under Windows that will accept only one parameter -- number of dots. At the output we're getting an black & white image (be it .bmp, .gif, .png, .jpg, .tiff) in any prefixed / rand...

@NewPosts !LOW QUALITY!

Seggan

i wanna say something like "this isnt a site where we code for you" but i just cant phrase it

Ginger

that's a close vote reason IIRC

hyper-neutrino

maybe the community-specific > go to SO one

although I think "no winning criterion" would probably be more accurate for this, as technically it could be a challenge. that or details and clarity, cuz idk what it's asking for

technically there is no rule against getting CGCC to write code for you but it needs to be a valid challenge and follow topic rules

(well, I guess the exception is homework/ongoing contests or similar)

Seggan

01:33

@hyper-neutrino yea ik but those just tick me off

bruh

Ginger

wtf did randall munroe do to this person

wait, that's satire

this one is legit

Seggan

03:16

@Ginger "Hello, World!"∈O works now :P

also this

ofc theres a billion todos

@emanresuA when will you test my PR?

emanresu A

06:07

Sorry forgot, will do now

On the off-chance that stdin works, what's the stdin command?

PyGamer0

there is no stdin

emanresu A

Ah okay

Also, did you test it yourself? All you really need to do is clone the repo and (depending on browser CORS stuff) run a localhost server (npx http-server is a good one)

PyGamer0

no i did not

@emanresuA tried running npx it doesn't work

node just doesnt work for me

emanresu A

Hmm, probably wouldn't be too hard for me to set up a gitpod instance...

gttg

dso-staging-pr-21.surge.sh if you wan to test suff

PyGamer0

@emanresuA yes IO works

just i can't use any flags (li need to change flax's code to handle that)

emanresu A

07:24

@PyGamer0 Merged and deployed

@Ginger In math notation this would be Cartesian product

does vba autoformat has some sort of inconsistence?

I have Cells.row and Cells.Column, apparently there is a discrimination against the word row by forcing lowercase on it

also Rows which is uppercase for some reason, I guess microsoft hate row specifically

and the autocomplete also shows Row(and does auto complete with Row instead of row), but the autoformat reverse it back to row when I move to other line

mousetail

10:13

LDQ What should happen if you use iterator functions, like map, filter, reduce on a number?

lyxal

Rangify from 1

mousetail

Why from one opposed to 0?

emanresu A

More useful

lyxal

^

Very rarely is 0 to n exclusive needed

1 to n inclusive has proven to be good 99% of the time

I've probably ever needed 0 to n exclusive a handful of times

mousetail

10:39

Hmm I was thinking decimal representation so things like count and index would do something useful

lyxal

10:51

Well for those you treat as list of digits

Basically, if list of digits makes more sense it takes priority, else rangify

mousetail

I don't really want to make it inconsistent

emanresu A

Yes you do

lyxal

^

If you go consistent, there'll always be cases where applying an operation on something isn't doing the most useful thing

Plus, it works just as well if you do it based on what would be the most intuitive option given context

mousetail

If I go inconsistent I'd need builtins for everything that is not done implicitly

lyxal

Not necessarily

Just have a range built in and a to digit list built-in and use those in the 1% of cases where the default behaviour isn't needed

mousetail

11:05

Yes, but that wastes a built in slot and I have 1 too many built ins already

lyxal

Well if you use a consistent method, you'd need those built-ins anyway

Plus, if you have overloads, you just place digit list on flatten

mousetail

I won't have overloads

lyxal

Why not

mousetail

Overload is basically the same thing as inconsistent behavior

lyxal

So you're just going to have errors when types of arguments to a built in don't make sense?

mousetail

11:12

There is going to be type coersion but that's different

lyxal

Then list of digits can still be placed onto flatten

It just coerces the number to a list of digits first

mousetail

Yes, so I won't need a builtin for number to string

lyxal

@mousetail but then what about when type coercion doesn't make sense? How do you take the range of a string?

How do you lowercase a number?

mousetail

It vecotriez

I won't have a difference between arrays and strings

or between chars and numbers

lyxal

So then there's no type coercion at all then

mousetail

11:20

Maybe technically not in this case

lyxal

Then you want to make sure you have good list handling built-ins because you don't have the usual string manipulation functions you usually have

mousetail

Yea I have a lot of list and string built ins. A lot of standard string built ins like replace, split, and join seem like they would be very useful even for non-string arrays

lyxal

That's true, but make sure you have other useful list stuff too like transpose, flatten, that sort of thing

mousetail

This is my current thought btw: github.com/mousetail/Cerebellum Very early draft still I might change everything

lyxal

What language are you using to implement?

mousetail

11:29

Probably Rust

lyxal

Shame. If you were using python, I'd mention that the multiple copies of lazy evaluated containers problem is easily fixed with itertools.tee

I don't know if there's a rust equivalent of that

mousetail

Managing many shared references to a list is going to be a bit of pain in Rust which is why I'm still unsure. The match syntax makes it very easy to write parsers though

lyxal

Scala could be of interest then. It does lazy evaluated stuff really nicely + has really good pattern matching

+ JVM for speed

also, have you considered digraphs

also also, no multi-digit literals?

mousetail

Nope, I'll have a base 255 number representation

It's in the quotes section

Or maybe base 128? Actually that's probably better since I can avoid needing a closing quote

lyxal

Are iterator commands actual commands or modifiers?

mousetail

11:37

I guess modifiers, they will return a copy

lyxal

modifiers being that they operate on tokens, not data

mousetail

Would lambda be a modifier? They all include a implicit lambda

lyxal

like how +/ modifies the + in Jelly and makes it reduce a list. Or how ~₂ modifies the ₂ in Vyxal and filters by it

mousetail

They are commands

lyxal

aha

mousetail

11:39

Splat and it's variants are the only modifier currently

lyxal

what happens if I give them two numbers or a number and a list?

mousetail

You can't give them two numbers, they implicitly start a new function so it's impossible to pass any parameter other than a function as the second argument.

lyxal

aha I think I know what you mean now

so they're "structures" in a sort of a fashion

got it

8 mins ago, by lyxal

also, have you considered digraphs

also also also, ternary conditional/if statements?

mousetail

I might need digraphs if I discover a significant amount of extra commands I want to add

lyxal

good, because there's currently some stuff you really don't want single byte when there's limited command space

mousetail

11:43

@lyxal There is a ternary, also a short circuiting "and" and "or" for providing default value

lyxal

"and" and "or" don't allow me to do if x then y else z though

mousetail

You would use the ternary

?xyz

lyxal

good

also, "Parent list"? What's that?

mousetail

Inside a map you can get the list you are mapping over

lyxal

clever

anyhow, I can see 9 things you would want to move into digraph space

meaning you would have 9 more command slots for doing stuff with

plus you get to remove a few string-specific things for a few extra free spaces

PyGamer0

11:48

@Seggan oh yeah that didn't go very far

but now i have minecraft java

mousetail

Don't hold me in suspense, what things?

lyxal

Current Time (Unix Time)
Current Time (ISO)
Current Time [year, month, day, hour, minute, second, millisecond]
Source Code
Filename
Read file
Write to file
Read HTTP
Post HTTP

string to number (base 10)
String to number, n decimal places (base 10)
stirng to number (base 16)
string to number (base N)

because some of those string base conversions can just be special cases for number to base whatever

mousetail

wow I'm incredibly inconsistent in my spelling of "string"

lyxal

didn't notice that, but lol

also, Recurse File and None could probably be moved to digraph space too

mousetail

True

lyxal

11:51

Also, None and True in a golfing language?

Just let numbers be booleans

mousetail

They are

lyxal

I know, but exclusively numbers

mousetail

For some specific cases there is a isNone check, otherwise they behave identically

lyxal

also, what happens if you give something like SortByKey a non-function argument?

mousetail

It also implicitly opens a function

Everything that takes a function does except the callFunction builtin

lyxal

11:53

what closes a function?

mousetail

nothing. Functions have a arity of 1 so I always know when it ends

lyxal

oh yeah this is prefix lol

I forgor

finally, any plans for the codepage yet?

mousetail

Not yet, I might just copy a codepage from something else

at least to get started

I can modify some things as I go

lyxal

fair enough

well that's all the questions I think I have for now

mousetail

Thanks a lot for your feedback

lyxal

11:57

I'll make sure to bombard you with 20000 more questions when you make some more progress :p

mousetail

I'd love that

Ginger

12:14

@Seggan ._.

lyxal

You say that like it's a bad thing

Ginger

I wasn't expecting that so quickly

I'm impressed

Seggan

13:46

@Ginger yeah i also implemented it half wrong, with the set contains adding the element instead of trying to make it true, so i gotta rewrite that

Ginger

lol

also bear in mind that in the context of an expression that function should check if the element is contained within the set!

Seggan

yeah ik that behavior was for the out set

Ginger

ok cool

Ginger

15:40

please help me

mousetail

Oh no, TVTropes

The site you can enter but never leave

mousetail

18:46

My new PC is finally shipped, should be here in a few days. Only 15 days after they promised

Ginger

19:37

cool
