Your challenge, should you choose to accept it, is to write a program in a language of your choice that, when given a string (limited to printable ASCII) as input, outputs a new program in the same language that outputs that string without using any characters from that string in the code. But th...

type spam can be used to sequence individual prints, but that still only makes (=) tie, since the prints need end=. — Unrelated String 18 mins ago

i cannot stop trying to think of some way to get past that

because the type spam is already such a weird damn trick that i refuse to believe i can't actually use it

actually wait newlines aren't printable ascii so it's completely irrelevant anyways lol

Q: It's Just Simple Math!

Task Your boss is on another crusade for 'efficiency.' He wants to encourage the use of numbers with fewer syllables, so that they're easier to discuss in meetings.

My butter is long thank you very much

@lyxal I sense a distinct shortage of butter

lyxal

why would you even suggest NMP has short butter?

@lyxal I have literally no idea what that refers to!

@NewPosts What about million, billion, ...?

how many syllables do they have?

mousetail

Text to number challenges are always very hard to define objectively

math scat

maybe a cap at one thousand could work

but the challenge doesn't seem very interesting in general

A: Sandbox for Proposed Challenges

How many twisted corners? Your challenge is to output the number of twisted corners given a 3x3 Rubik's Cube scramble. For the purpose of this challenge, twisted corners are defined as corners where the colour of the top/bottom face (usually white or yellow) is not facing the top/bottom. A scramb...

Its counterpart, how many flipped edges is actually a key step in the zz speedcubing method.

whereas the former isn't useful for speedcubing but rather for rubik's cube theory.

So, uh, noodle man's most recent challenge is almost identical to one of the challenges I proposed in the sandbox a few days ago...?

I guess he decided it was either long enough that it had been abandoned, or that the addition of a scoring metric made it distinct enough that it was a separate challenge

@noodleman

At least I know it's not a case of inadvertent duplication because noodle man commented on my sandbox submission

noodle man

15:45

@97.100.97.109 oh crap i totally forgot about that i’m sorry

i wasn’t trying to copy yours but i realize totally i did (albeit accidentally)

when i thought of posted it i posed it as a CMC in the CGCC discord, i’m surprised nobody noticed my mistake

if i posted it in the sandbox before posting i would’ve noticed that it was a dupe, that was a total oversight

can i give you a bounty or something?

Neil

16:10

@97.100.97.109 actually I asked this as a CMC a couple of weeks ago...

97.100.97.109

16:48

@noodleman It's fine, lol, I just wanted to know that happened -- I don't need anything from you :)

It's funny that three people came up with the same challenge idea within a few weeks of each other

noodle man

alright then

also i think the version you originally posted was impossible in most langs lol

97.100.97.109

@SandboxPosts I would be interested in seeing if this challenge is too similar -- it's the same idea, except without the scoring metric and by forbidding substrings instead of character sets

(As an attempt to fix the issue mentioned above)

noodle man

oh interesting

i’m still not sure it’s possible though

say the input is “lambda”

97.100.97.109

then do print("\'lamb\141')

(Since both stdin/stdout and function input/output are valid code golf solution methods)

noodle man

“lambda print exec”

97.100.97.109

16:58

print('lambd\141 print exec'), since that doesn't contain lambda print exec as a substring

noodle man

oh wait nvm i misread

97.100.97.109

Or you could just use the unicode normalization honestly

noodle man

yeah that seems pretty good although i’m not sure it will be possible in all languages

97.100.97.109

Yeah, that's fair -- I also think that's okay

noodle man

i think it’s a more interesting challenge than what i posted

SBCS langs will still win easily tho

97.100.97.109

17:01

In some cases, maybe -- but for Python specifically, I think it's not particularly interesting

This challenge is also trivial a language like Vyxal I think

noodle man

the challenge i posted kinda boils down to “smallest number of unique chars to print a string”

also i think i just found a mobile chat bug lol

97.100.97.109

?

noodle man

i don’t know what caused it but when i clicked edit on the message “a little like…” it showed a loading spinner in front of the textbox

i can’t edit it anymore because it’s been too long, and i didn’t get a screenshot

wait the message never sent?? i reloaded the page it’s not there

weird

anyone have thoughts on this I/O default i proposed? codegolf.meta.stackexchange.com/a/26095/108687

it’s sort of used by some TS types answers already so i wanted to see if it was generally applicable

noodle man

in TS types this is generally used by having the submission be a union type, and having truthy/falsely be whether a literal type is assignable to that union (error or success)

i feel like types can be considered predicates in a stronger sense than what you'd generally consider a set in a programming context

AAAAAAAAAAAAAAA
i was so sure i had a 2 figured out but it turns out fullwidth underscores are illegal despite normalizing to ascii underscores

maybe there's something else that normalizes to an underscore

found two more and they're also illegal

i guess there's probably a "call unicode symbols illegal" step before the "normalize unicode in identifiers" step
