you'd gimp your ability to use full unicode that way but it's still interesting

Browncat Programs

Modding by code page size sounds like an unusual detail

DLosc

This is intended for a language where a lot of operations vectorize over lists, with the idea that the same operations would vectorize over strings too.

@BrowncatPrograms @UnrelatedString "Code page" could be "all of UTF-8" if desired

Unrelated String

true

Browncat Programs

@DLosc Why not just have a different set of overloads for strings, that only vectorize when needed (and do it reasonably)?

DLosc

More work, less orthogonal?

Browncat Programs

17:01

More golfy

Better idea: represent strings as lists of code points, then represent everything according to

Aug 24 at 23:54, by Dude coinheringaahing

CMC: Given a list containing either integers, or lists of integers or lists (and etc.), encode every list as a base n+1 integer where n is the largest element in that list. [1,[2,6,7,[8,9]],3,[[4,[10]]],5] -> 10324088012575466278494485 Steps

i would say also that using a smaller implicit modulo could be useful for, like, multiplying by a magic constant to transliterate something

caird coinheringaahing

@cairdcoinheringaahing Sooner or later, I'm creating a language based around this

Browncat Programs

IMO there are two reasonable string representations, and anything else is just overcomplicating one of the two

Aaron Miller

17:02

@BrowncatPrograms *cough* Vyxal *cough*

caird coinheringaahing

@AaronMiller He said "reasonably" :P

Browncat Programs

@BrowncatPrograms Either strings are strings and that's it, or strings are arrays of a character type

Aaron Miller

lol

pVC aecidiospore adduced

@AaronMiller not mine :P

ok i am kidding

Aaron Miller

only weaknesses? :P

caird coinheringaahing

17:03

@BrowncatPrograms I think arrays of integers representing code points is also a valid representation

pVC aecidiospore adduced

@AaronMiller yes

caird coinheringaahing

Especially for lower level languages

Unrelated String

^

Browncat Programs

I'd just call those characters though

Unrelated String

fair enough

caird coinheringaahing

17:04

Might be semantics, but I'd see a slight difference between the two

Not enough to argue about tho

Aaron Miller

Why not just get rid of strings completely and just use binary?

Browncat Programs

Well, I'd consider it a third then

But that's not one golfing languages would usually use

Unrelated String

yes
replace all arrays with a single bigint

that's actually an interesting idea

hyper-neutrino

just get rid of strings completely

no more strings. this language cannot solve string manipulation challenges

Unrelated String

true

Browncat Programs

17:05

@hyper-neutrino You say that jokingly as I write a string manipulation library for brainfuck :p

DLosc

@UnrelatedString Sounds good

Q: Silly sentence generator

Your challenge is to input a word and find all words enclosed within angle brackets. (< and >) Here is an example: The <adjective> <noun> biked across the bridge. Next, replace all <noun>s with a random noun, all <verb>s with a random verb, all <adjectives>s with a random adjective, and all <adverb

Thomas Ward

i mean i'm tempted to do something for ^^ that in Python but i know i'll instantly be outgolfed xD

caird coinheringaahing

@NewPosts OP definitely needs to start using the Sandbox

Thomas Ward

i also agree with ^^ that

@cairdcoinheringaahing sounds like you should comment that saying "Start using the sandbox first!"

'test cases: none" doesn't sit right with me

there's always ways to create a test case and show example output

(even if 'random' is involved)

Razetime

17:33

@ThomasWard yep, they are very prompt with that.

Browncat Programs

@DLosc Beware, using it on chrome messes up the audio playing permissions, so if you've made it so a tab can always play audio muting it will restore it back to requiring interaction first

That's why I stopped using it for TNB

DLosc

@NewPosts Alas... I sympathize with what OP is trying to do, but it doesn't fit the squeeze-every-byte spirit of code golf.

caird coinheringaahing

I have a quick comment (alt+4) specifically with "You should start using the Sandbox" prefilled

DLosc

17:37

@cairdcoinheringaahing It's working!

caird coinheringaahing

Not exactly as intended tho :P

Aaron Miller

Should the question be closed until it's done in the sandbox so that people don't answer it?

DLosc

Probably

caird coinheringaahing

I've advised them to delete the main post (then undelete and edit once clarified)

DLosc

@BrowncatPrograms I... don't know what that means. :P But anyway, I'm on Firefox right now.

Browncat Programs

17:42

Ah, ok :p

I have TNB set to always be able to play audio, since it usually requires interacting with the page in some way first, since I wasn't getting pings if I had it open in the background and it reloaded. Any time I'd mute the tab and unmute it, it'd reset those settings.

Thomas Ward

18:01

yeah well it's not being kept

caird coinheringaahing

I'd suggest not keeping the code, preparing answers for Sandboxing questions can be frowned on :P

Thomas Ward

this isn't being kept

it's literally just what i typed up in Python xD

on IDLE

it erases since it's never kept

caird coinheringaahing

@ThomasWard Ah, you ninja'd me :P

Thomas Ward

it isn't being kept, but minus capitalization, 127 bytes, but requires an import from standard libs xD

literallyw as bored

caird coinheringaahing

fair enough :P

127 bytes in Python sounds reasonably short for that tbh

@ThomasWard random?

Thomas Ward

18:04

122 bytes because i realized i added extra crap that wasn't needed

but basically, yes. random.choice

probably against the rules, but i was curious if i could just do it :P

i.e. not competitive, "took it as a micro challenge for myself"

caird coinheringaahing

@ThomasWard Nah, standard libraries are perfectly fine

I'd be surprised if you could get <200 bytes on a random challenge without using import random (or any other imports) in Python

Thomas Ward

@cairdcoinheringaahing well, that's the core bits, making two assumptions: (1) the string to parse is stored in a variable (s in this case), and (2) the list of words and word types is populated (like specified in the original post) already and not part of the actual 'how to do this' stuff).

it becomes too large to be considered 'golfing' if you have to include population of the word lists (tio.run's 'header' is good xD)

yawns

little microchallenge to make sure my brain can do stuff :)

caird coinheringaahing

@ThomasWard That's my biggest concern about the challenge tbh, I suspect that most answers are going to waste/spend a lot of bytes just encoding the word lists, and that's never the fun part of golfing :/

Thomas Ward

yeah their sandboxed version rewrote it to provide the lists

so there's no 'use your own' but yeah that's a question: "Should we include populating the word lists or the string to parse and process in the code count" is a concern

i'd ask but i'm lazy

and i'm still working i just needed the break from the Postfix hell i'm in

caird coinheringaahing

@ThomasWard I remember a couple of years back, someone would see a post in the Sandbox, immediately draft up an answer and spend the time working on golfing it, so that when the challenge was posted after a few days, they'd have an answer posted in seconds that was already golfed

Thomas Ward

18:09

i'm assuming the answer to that would be "no, just your implementations"

hah yeah well

as i said before, this is me just microchallenging myself

i have no intention to ever post it, even if i forgot to delete the code

caird coinheringaahing

Understandably, people got annoyed and so we discourage working on actually solving (and saving) answers to sandboxed challenges :P

Thomas Ward

yep

I use CGCC and some of these things as random coding challenges for me to take a stab at privately

i have no intention to actually compete right now :)

caird coinheringaahing

@ThomasWard I do the same :P I also try to create a solution to the Sandbox challenge to see if it's clear enough to be on main, and to find areas that aren't as clear :P

Thomas Ward

yep

like in this case i have a question for clarification :p

@cairdcoinheringaahing there used to be a meta thread with 'generally accepted assumptions and rules' for golfing, where'd that go, or was it replaced/removed?

(i.e. the statement that 'standard libs and usage therein are permitted' being stated as a general rule)

caird coinheringaahing

There's the standard forbidden loopholes, but that's about what isn't allowed rather than what is

There's also the unspoken challenge rules

I think that generally, unless something is explicitly banned, it's ok to do here (such as using standard libs)

Thomas Ward

18:16

well I'd assume that if someone's happening to golf in a language that has standard libs, like Python or such, it'd be too restrictive to not use them when random is at play

Anush

CMQ which words start with the sound of a letter which is not the letter it starts with? E.g. euphemism?

Thomas Ward

because otherwise you have to write a random number generator, which in itself is painful as heck, and needs standard libs in Python anyways xD

Anush

(just for fun :) )

Browncat Programs

@Anush you

caird coinheringaahing

@Anush Any word beginning with eu (euphoria, eutopia, etc.)

Anush

18:17

@cairdcoinheringaahing yes

caird coinheringaahing

@ThomasWard It'd be interesting to see if you can write a PRNG in vanilla Python

... wait how do you pronounce that

Browncat Programs

B, D, G, H, J, O, P, T, W are the only ones left I think

hyper-neutrino

18:27

also doesn't "air" start with the "a" sound too

DLosc

@BrowncatPrograms Ewe

Browncat Programs

@hyper-neutrino Wait it does yes

Thomas Ward

@hyper-neutrino and 'ex-' starts with the X sound

:P

Browncat Programs

@BrowncatPrograms I misread that

Art is R, Ink is E, Air is A

hyper-neutrino

double-u (:p)

Browncat Programs

18:28

Unless there's some obscure loanword, I don't think any more progress is possible, except maybe for O

If you have a weird accent, ate for H maybe

Actually I have a weird accent apparently

Ate ~= H when followed by some words

Like "your"

hyper-neutrino

surely there's a word starting with J that sounds like it starts with the name for "G"

Browncat Programs

True

Jeer

Jingle

Plus some names and loanwords

There's gotta be something for O

DLosc

@BrowncatPrograms I've always been unsure whether the "ing" sound is pronounced with the vowel in KIT (/ɪ/) or the vowel in FLEECE (/i/)--my instincts told me /i/, but the IPA transcriptions I saw all said /ɪ/. Now I see that the Wiktionary page for ink says some American dialects do pronounce it with /i/. Interesting!

@BrowncatPrograms I was thinking "eau," but apparently that's still considered French, even though it's a technical term in perfume ingredients.

Browncat Programs

B, D, P, and T are almost certainly impossible I think

DLosc

Aubergine!

Browncat Programs

18:36

Nice!

caird coinheringaahing

@hyper-neutrino Jif

@Anush Gif

Browncat Programs

How...how do you pronounce that

"Jayf"?

DLosc

Zhyfe

caird coinheringaahing

"Gif" is with a soft g, "Jif" is with a hard g, duh :P

hyper-neutrino

ಠ_ಠ

even then it's not the name of "J" if it's "ji" and not "jay"

please don't tell me you pronounce the i as a long a

caird coinheringaahing

18:38

What, what's "the name for G"?

Browncat Programs

First part of "Jingle" or "Jeer"

caird coinheringaahing

Not "gee"?

DLosc

(Go with Jeer if you're not a speaker of certain American dialects)

Or Jeep

caird coinheringaahing

Jeer/Jeep start with a "djuh" sound :P

DLosc

R, L, and nasals mess up the pronunciation of vowels

Browncat Programs

18:40

@cairdcoinheringaahing Yeah, "djee"

Do you pronounce it with an actual g sound?

Alan Bagel

@BrowncatPrograms I think so

Browncat Programs

So like "geek" without the "k"?

That sounds very weird to me :p

Alan Bagel

@BrowncatPrograms No, I meant like saying the letter G

Browncat Programs

Oh

DLosc

@BrowncatPrograms Did we find one for V?

Browncat Programs

18:45

No

I forgot V was a thing

Four circles to the kissing come.
The smaller are the benter.
The bend is just the inverse of
The distance from the centre.
Though their intrigue left Euclid dumb
There’s now no need for rule of thumb.
Since zero bend’s a dead straight line
And concave bends have minus sign,
The sum of the squares of all four bends
Is half the square of their sum.
