can't do that yet can I?

true

okay have patience then

hey does the macgyver's toolbox thing need a full program?

a program or a function i think

11:03 AM

so we can return 37?

instead of printing it?

that would save tons of bytes and keep some characters for my go answer

Oh nevermind:
> You must write a valid program in one of the languages provided using only the characters in the toolbox. Your program should output the number of answers already present on this question.

never mind again

> You may write either a full program or a function as your answer. Since REPLs are different languages they will not be allowed. (use the TIO version of every language)

lol

here

this should be vali, right?

yep

i just edited the post so it says program/function instead of program now

so it doesn't contradict itself

alright getting next tool box...

oh good @totallyhuman glad to see you're doing Go :D

11:12 AM

you asked for something awesome, i delivered... a 20-byte solution in go?

@totallyhuman you can't get the next toolbox before posting the answer

yeah but i have to remove every character i used so i'm doing that rn

I might do a SILOS one next

I have an Agony solution ready to post right after totallyhuman ;)

aww, i'll do SILOS after you then... depending on what characters you use up

11:15 AM

Only + and ., that okay?

well it depends on what totallyhuman's Go answer uses up too, SILOS is a little verbose

hmm might not be able to do SILOS, I need int

we have D lang now

I'll have to wait and see what new chars are added after yours and Okx's posts

Sidenote: this challenge is a really cool idea

Kudos to WW

ok i hope i did everything right...

Q: Compute OEIS A005434

The task is to compute OEIS A005434 as quickly as possible. Consider a binary string S of length n. Indexing from 1, we can determine if S[1..i+1] matches S[n-i..n] exactly for all i in order from 0 to n-1. For example, S = 01010 gives [Y, N, Y, N, Y]. This is because 0 matches 0, 0...

Lembik

@MartinEnder Hi.. Yes I am back on binary arrays :)

11:59 AM

@Mayube Sorry! I was unaware that you were working on the same one. Just saw that the toolbox included an interesting language I'd never seen before that seemed easy enough to do with the chars available, so I figured I'd go for it :/

@Emigna no worries, I managed to do reticular after you :)

that's competition folks

@Emigna yours seems a little more interesting than mine anyway, which was just 51 +'s, a ., 6 more + then another .

It is a pretty cool challenge for discovering new languages :)

agreed!

12:05 PM

I tried logicode and closure yesterday, but was missing a crucial char for each (afaik).

I tried uBASIC, but kept getting a syntax error and couldn't find good enough documentation to figure out why

everyone needs a subset of C++ :)

preferably a very small one

Templates Considered Harmful is a programming language composed of C++ templates, which is executed by having a C++11-enabled compiler evaluate a typedef

github.com/feresum/tmp-lang no onebox pls

@WheatWizard just wanna say, thanks for the MacGyver challenge, it's a little unorthodox as far as challenges go, but it's really fun

however refilling 12 chars each time is definitely too much

Yeah

Anonymous

@Mayube I don't think GitHub repos get oneboxed

I might want to do a rerun with less characters

12:34 PM

if you look at the wsl entry for example, it used 3 characters, meaning those 3 plus 9 others were refilled

at the same time though you don't want it toolow

cos otherwise a language like Java or C comes along and uses up half the lowercase letters and some of the most used symbols

and you don't want to reach a toolbox lock-state, where none of the languages in the toolbox can complete the task with the characters allowed

I think I am going take the average from this one make it the new number of added characters and throw in a saving grace type mechanic

good idea

just hope your "fixed" version won't get dupe-hammered

Perhaps the old can be duped

oh yeah good point

Pavel suggested a scrabble "blank" tile be added

12:37 PM

ah so a sort of wildcard character?

user165474

I just realized that I made one of my old challenges a subset of a newer challenge; maybe the older one should be duped? idk

user165474

though the old one is like 1000x easier and has some cool tricks to do it

@HyperNeutrino what do you mean by "translated"

@cairdcoinheringaahing Unless I'm misunderstanding, it seems like <take_input><print_S> would be the most efficient method for any golfing language with the current scoring method

@Emigna scoring is the issue I'm trying to fix. I'm thinking of having a minimum number of recipes that must be handled e.g. 5

That would definitely be an improvement

Strange realization: outputting via exit code is always shorter than printing a boolean in Python

You just 1/value instead of print value. Except I guess that negates it :O
