The Nineteenth Byte

12:45 AM

ok

Welcome to this week's Learn You A Lang for Great Good! Today, we'll be learning Labyrinth. During the event, feel free to post CMCs to practice Labyrinth (LMCs), ask questions about the language, and so on.

Labyrinth is a 2D language based on the path-following mechanic. All non-instructions (including spaces) form a wall, and the instruction pointer (IP) follows the path formed by the instructions. Conditional branching is done at three-way or four-way junctions, and loops can be formed by creating loops in the path.

All the commands (not many) and detailed semantics can be found in the readme linked above.

LMC: Given n, calculate factorial of n

LMC: No input, print 0 or 1 randomly (both nonzero chance)

it's been a while since i've done any labyrinth, i'm a little lost ;)

lyxal

guess you'll have to check how many neighbours you have then

@JoKing Well, it is a pretty maze-like language until you find your way

I have something that doesn't work for 0 lol

@Bubbler 18 bytes

it took me a bit to figure out 0 too

checks vanilla factorial question, just as i predicted, past me got it in two less bytes

1:23 AM

:P

note: two size 2 loops can beat out a size 3 loop

how do you do detailed debug mode on TIO again? -d doesn't seem to work

@Bubbler 7 bytes

I feel so sorry for anyone who answered a slightly-complex math question before we had Mathjax, having to use images, or <sup> tags :(

Having updated enough of them to Mathjax, I can imagine the pain of writing them in the first place

Yeah lol

There are so, so few resources out there on server-side MathJax rendering

Would be a great topic for my first blog post if I didn't need to figure out how to do server-side MathJax rendering to get my blog to work in the first place

I've, for possibly the first time, come across an error message that literally nobody else has had. I've gotten close a few times, where all that exists is one or two references to it, but this brings up nothing but MathJax's source code where the error is emitted.

MathJax: can't insert css rule '[ SOME CSS ]': Cannot read properties of null (reading 'insertRule')

Damn I'm pretty good at this whole COVID thing, I've infected 2/3 of my other family members now

@user Yeah, that's a possible meaning too. I was being a bit jokey with my response, though it was the first meaning that came to my mind.

@RadvylfPrograms Meh, just 66%? Gotta get 100% for that A+

lyxal

@RadvylfPrograms how's covid treating you btw?

4:06 AM

weirdly shaped factorial, 22 bytes

huh, there's no swap command in Labyrinth?

LMC: take n, output nth abacaba sequence but with numbers. n=1 -> [1]; n=3 -> [1, 2, 1, 3, 1, 2, 1] (output format is permissive)

yeah

that's a pain

Q: shortest runtime bytecode question

What is the shortest runtime bytecode you can write for a contract that satisfies both the following: Accepts calldata of length 32 bytes representing one uint256 (no function selector) Returns, as one uint256, the fibonacci number at the index of the input (the sequence can start at either 0 or ...

fibonacci

@NewPosts hmm it seems like a genuine code golf challenge attempt but they havent quite gotten the format

agreed

6:05 AM

Seems like a dupe

6:59 AM

@Bubbler oh no, there's no command to swap the stacks either, rip my solution

lol

apparently way harder than it looks

i also keep getting caught out by the n*10+x way of pushing, oof

@Bubbler 40 bytes but i can't be bothered to output it properly

awesome

Same user presumably

TODO: Create a userscript that reminds me to edit in code-golf if I want to dupe hammer

mousetail

That's a pretty dumb loophole

You could always add a tag, close the question, then remove the tag again if you have at least one gold tag

Solidity is a statically-typed curly-braces programming language

@emanresuA If you edit the tags to include a tag you have a gold badge in, you can't dupe hammer

i wasn't aware "curly braces" could be a defining category

9:53 AM

@cairdcoinheringaahing Huh okay

That's good

when will NP/SP come back?

Whenever radvylf / someone finds the time to fix them

SE made a major API change without telling anyone, as usual

Does CCCG still have a nearly 50% HNQ rate? meta.stackexchange.com/questions/232097/…

Wouldn't surprise me

It's currently 55%

Updated SEDE query

That looks like a very complicated query lol
