Q: Output Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo

Challenge The goal is to output Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo. Context. (Maybe another interesting challenge could be printing all of the other examples? This would probably use similar logic but involve either a function or just a for loop.) Rules You cannot ou...

@cairdcoinheringaahing If that's the whole point, just shuffle the built in functions and imported modules in Python (or something).

@RedwolfPrograms 32768 is a power of 2 , integer range?

@cairdcoinheringaahing I feel like I've seen this somewhere before

The whole entire triples then doubles then singles approach

Hmm.... totally doesn't remind me of my own failed attempt at tacicity

2:47 AM

Anyone feel like prepending something like meta.stackexchange.com/a/360350/388243 to the (question) sandbox post?

@cairdcoinheringaahing help: how to make a function in Orst?

okay nvm

I just wrap code in {}

4:04 AM

Looks like all but one of my nominations for Best of are doing well.

I should have bet money on them.

@cairdcoinheringaahing Wow, this is the perfect language to make you win popularity-contests! I've been trying very hard to design a language just like this, to no avail.

I fell in love with the language at first sight :P

@2x-1 You do realize it’s supposed to make you hate it, roght?

@user I don't see the point of hating it. It's the cleverest esolang I've ever seen!

Well, I guess love knows no bounds :)

So, anyone want to bet on the winners of Best of CGCC?

@user BTW, what I like the most about Hatred is that there isn't even an interpreter for the language. Let's keep it that way.

Imagine this: an empty repository with 50 stars!

4:15 AM

Yes, there’s enough evil in the world already, like INTERCAL.

CMC: Everyone, star the Hatred repository!

Redwolf Programs

Speaking of commands that don't do what you want them to, JS's typeof is horrible

That'd be a good thing to add to Hatred; just skip the 1% of times it works and always return "object" :p

@RedwolfPrograms Works in kolmogorov-complexity challenges where you could encode the string "object" in a single byte :p

Redwolf Programs

Honestly typeof isn't that bad if you don't care about arrays, which is like saying eating a pillow isn't bad if you don't care about food

4:45 AM

@cairdcoinheringaahing how does array indexing work in Add++?

Hey have y'all ever made a rock pile?

They are surprisingly fun to make

Just sayin'

@Lyxal Its IMO the most basic approach to parsing a fixed arity tacit chain, just the patterns are horrible

@Razetime Try it online! index goes below the list on the stack stack.pop()[stack.pop()]

10:59 AM

Add++ and its function stuff is sometimes aaaaaa

caird coinheringaahing

@Razetime It's a good example of why you should code to a spec, rather than write a spec for some code

Reject modernity. Return to tradition. Embrace orst

@cairdcoinheringaahing do square brackets do anything special in Orst?

Or are they just built-ins

caird coinheringaahing

@Lyxal Errr, I can't remember

Lol

Also it seems I'm the top language answerer for orst

Given mines the only answer on the site

(only orst answer that is)

What's the inspiration for the name?

@cairdcoinheringaahing ^

@Lyxal Errr, I can't remember

I think its because it was a shorter better version of Deorst

Unrelated String

makes sense

I like it

I like it a lot

Unrelated String

love the use of Cyrillic ligatures in the double-byte codepage

love how tio just gives up on byte counting

caird coinheringaahing

I think I asked Dennis to use the "its complicated" beccause ¯\_(ツ)_/¯

Unrelated String

11:19 AM

lol

...how does the encoding actually work

caird coinheringaahing

So I made the language like 2 and a half years ago, I've forgotten how half of the language works :P

Unrelated String

:P

caird coinheringaahing

Let me just bring up the repo, cause I can usually figure out my own code

Unrelated String

the code page on the wiki doesn't have any obvious byte reserved for a combination

but I'm assuming that that is what the deal is

considering that each character is "one or two" bytes, and there's...

Absolutely amazing that + doesn't do addition

caird coinheringaahing

11:24 AM

github.com/cairdcoinheringaahing/Orst-Geo/blob/master/…

That's the decode function

if byte == 0xff:
            continue_byte = True
            byte += bytestring[index + 1] + 1

Unrelated String

...if one codepoint is reserved for two-byte combinations then it would only be 511 characters wouoldn't it

or am i asleep

caird coinheringaahing

More likely I made a mistake :P

Also, amazing that I can't easily push 0

Very cool

caird coinheringaahing

Reject modernity. Return to tradition. Embrace orst

Exactly

caird coinheringaahing

11:26 AM

I cant really remember why I made the language

Unrelated String

something is definitely weird here on multiple fronts because 0xff is supposed to be newline

unless it's because of the characters that get deleted from the codepage string after you initialize it

caird coinheringaahing

Think it was an attempt to match Jelly/05AB1E in golfing

Unrelated String

wait how would that work

All these gosh darn new golfing languages allowing you to push the number 0 without a parsing error

Unrelated String

smh

11:27 AM

Orst does it properly

If you try to push a plain 0, it calls you up on your weakness

It shows you who's boss

caird coinheringaahing

There's a reason Lyxal is the only person to have used it on the site

Unrelated String

yeah

Okay so you can actually push plain 0

Unrelated String

also do you have any idea why you made Geo

Just not at the end of a program

0 breaks the interpreter. 0 doesn't

caird coinheringaahing

11:29 AM

I think I made both languages while I was learning how base encoding and byte encoding properly works, so I made languages around those premises

Unrelated String

so Geo was sort of an exercise in how you could compress a Boolean matrix into something else

Q: How to make Roblox follow bot website

do you know how can I make a roblox follow bot website I tried but its not working Plus im using glitch as a website so please give codes according to glitch

@UnrelatedString The code page in the wiki doesn't match the actual code page used by the interpreter

@Lyxal Array syntax

1 hour later…

caird coinheringaahing

2:48 PM

Could someone whose familiar with Ruby take a look at this answer, I'm not sure if the I/O method is invalid or not.

3:33 PM

@cairdcoinheringaahing They're extending the Array class to incorporate z as a function

so that it can be called directly on any array

so b isn't predefined

If you're fine with allowing extending the language to create a zipwith function, then that is correct

caird coinheringaahing

@Razetime Yeah, idk if that's a valid I/O method tho

if your challenge says its okay its okay

otherwise ask them to take the array as a parameter

caird coinheringaahing

@Razetime My challenge says that only the default allowed I/O methods are allowed

hmm then extending the language isn't correct

1 hour later…

I need help from someone who knows the TIO API

@Razetime I've got some experience with it. Should we move to talk.tio?

sure

6:50 PM

Is there a terminal (for linux) that shows Tamil properly? This looks fine here for example அகத்திக்கீரை but looks really bad in the terminal window

7:35 PM

@Anush apt-get install konsole?

@Adám ah, so QuadR tries to match each pattern in turn at each position in turn, moving on to the rest of the string every time it makes a replacement?

in that case, it sounds like it's what this guy needs: unix.stackexchange.com/q/631850

@Neil Yup. afaik, Dyalog APL was the only language with that feature until Retina copied it.

7:50 PM

@Adám no, Retina doesn't match in parallel... if you try that QuadR program in Retina, it fails horribly

@ngn I will try that!

@Neil Thanks. Posted.

Gosh diddly darn morning y'all

Redwolf Programs

Good afternoon!

I've been thinking a lot and I think I'm going to make Ash stack based instead.

It's boring, but I'm not necessarily trying to make it interesting; I'm trying to make it intuitive and effective at golfing.

@RedwolfPrograms have you compared which would be hypothetically shorter through examples?

Redwolf Programs

They're exactly the same length for most things, and for anything involving variable numbers of arguments the stack based option is shorter.

If you made the current version of Ash postfix instead of prefix, it pretty much would be the same experience as using a stack based language, but more limited

Well welcome to the stack club!

Redwolf Programs

10:31 PM

No wonder they call it the stack exchange

I mean, I don't think you're wrong - they probably call it that because of Stack Overflow, and that's called that because of...stacks.

Exactly

I just realized I used // for comments in an explanation for a Python answer.

Too much Java on my mind

Well played

10:47 PM

Looks like there's going to be some competition between Vim and Whispers for Language of the Month next month.

Looks like Vim has won

Don't you mean ARM?

No, I just voted for Vim

I saw that @cairdcoinheringaahing used tabs to indent their Hatred code, and decided to punish them for it.

Well now whispers is lotm

Wait, did you just remove your upvote and downvote Vim?

Yee

Caird ftw

Caird forever

Caird is love caird is life

10:52 PM

They've still both got the same number of upvotes, though.

It goes off net total

Oh ok

@Lyxal Could more people star this?

@cairdcoinheringaahing notice me senpai

Your language is lotm

Come and celebrate with us

Factor (which was way late in the game) is surprisingly at +7, tying ARM and Vim

Nice

@Bubbler How easy is it to learn (and how fun is golfing in it?)

10:56 PM

From my understanding, think forth but easier

Well, I haven't actually tried Forth out either, but OK

It's not very hard, it's a high-level language that happens to be stack-based

Forth looks easy but then you get into the low level stuff

And from there you just die

Forth is hard because it's pretty low level, Factor doesn't have that kind of barrier

Thank goodness

10:59 PM

Golfing it is pretty cool. You don't even need to count imports when the interpreter can do that for you

@user I didn't like the stock

A: Sandbox for Proposed Challenges

Golf this Thumb-2 constant! code-golf integer bitwise number decision-problem Hopefully these tags are correct The sequel to my adds challenge. Hopefully more people like it, as it replaces text parsing with some bitwise operations. One thing that is constantly frustrating when golfing ARM Thumb...

And for math guys, Factor implements the whole numeric tower (bigints, rationals, floats, complex numbers supporting them).

Sounds tasty and fresh

@Bubbler Nice. I need to try it out.

11:13 PM

So apparently 05AB1E's Z (maximum of list) deep flattens the list first then gets the maximum element

good to know

CMQ: Should a list of 0s be considered truthy?

E.g. bool([0, 0, 0, 0])

I know python says it's true, but it doesn't feel truthy

Just created Factor chatroom for anyone interested

@Lyxal It's your call, you could call a list falsy if all of its contents are falsy, or if any of its contents are falsy, etc.

Like having an implicit any() or all()

11:50 PM

someone needs to write an esolang called Stack Exchange whose premise is exchanging stacks

@Neil On it.

Well, Stack Cats can exchange stacks

I can't imagine how exchanging stacks would be of use, unless you can operate the contents of the stacks too

Or is it stacks of stacks of stacks of ...?

Ooh, a Turing-complete language where the only data type is a stack. Is it possible?

I think it's definitely possible, because you can represent numbers with stack height

I just made a room for it. Let's see how it goes.

11:59 PM

@Bubbler it's stacks all the way down!

I'm thinking of something like BF for while loops
