wow .golf sites are expensive

i think my golf together thing will go on golf.rubenverg.com for a while(:

Yep :(

mousetail

I'm probably gonna go with a different TLD for that reason

Redz

@RubenVerg half of them might be actual golf :P

mousetail

I think all except 2 are for actual golf

Redz

yeah makes sense

mousetail

I imagine all codegolf related sites would be well known here

Redz

I only know code.golf and cgcc

do you know of any other good ones?

mousetail

There is anagol

Used to be week.golf but it died. I'm building a new one (early demo at yq.mousetail.nl) but it will be a while before it's good

RubenVerg is also building one

Themoonisacheese

09:13

@mousetail how the fuck do you even get 7 chars in just print? print() is already that much

emanresu A

hacks ;)

mousetail

@Themoonisacheese I don't use print

emanresu A

There is one other function that prints to stdout by default

The Empty String Photographer

@mousetail not all my solutions are terrible tho

mousetail

To that question, yes they are

The Empty String Photographer

09:18

Maybe just two of them

l4m2

Brainfuck has only one control flow: while. And it still make unreadable code. It must be while's fault!

mousetail

While is just goto in disguise

@TheEmptyStringPhotographer None have the score listed

Themoonisacheese

we did it, we did all the algorithms

@mousetail every branch is a goto in disguise

even function calls

mousetail

I guess this solved P=NP, if an algorithm existed to convert a NP problem to P then it would exist in that repostory

Redz

@mousetail and the scariest part is it makes sense

mousetail

09:21

do {}while() is the most directly equivalent to a goto. Most other loops and functions are also just goto with more extra steps.

emanresu A

@TheEmptyStringPhotographer The intent of that question is to use googlology concepts to construct extremely large numbers, not to bash together evals and for loops and hope that you get a big number out of it. To date, you haven't bothered to score any of them (if they even terminate at all), and the ones that do terminate are bounded far above by f_omega^omega. I suggest you actually read up on googlology, rather than continuing to submit answers that are not far from being flagged as "not a serious contender".

RubenVerg

@emanresuA ah, right... this got me to 9

emanresu A

Nice :p

RubenVerg

though not sure how it becomes 7

emanresu A

see if you can get it to 7

hint: that function returns None which arithmetic ops don't like

RubenVerg

09:23

wait i count 8 not 9

is it counting a final newline i don't have?

emanresu A

I suspect it's windows being windows

i.e. CRLFs

but yeah should be 8

RubenVerg

oh

yeah changed it to the other way to separate statements and got to 8

Themoonisacheese

the way microsoft could simply decide to switch to CR and doesn't is killing me

RubenVerg

they could also decide to switch to LFCR for extra fun

@emanresuA thanks

emanresu A

Nice

Themoonisacheese

09:26

@RubenVerg depending on implementation LF erases the current line on the terminal

RubenVerg

@Themoonisacheese would have to replace all my .split(/\r?\n/) with .split(/[\r\n]/)

ungolfs

lyxal

@Themoonisacheese jokes aside, this seems like it could be really helpful for golflang designers

From what I can tell it's a sort of standard library of algorithms

Probably a pain to bundle and not plausible for hosting on a site like pythonanywhere

But useful nonetheless I imagine

RubenVerg

oh, winning the hole in nodejs

emanresu A

There's a nodejs one now?

I set myself up a reverse shell inside the docker container only to realise the whole thing's open-source

lyxal

Ooh it even comes with a bogosort

RubenVerg

09:33

@emanresuA yeah s/python/nodejs/ in the url

emanresu A

Feel free to delete those experiments (challenge #4) @mousetail

RubenVerg

would be much shorter in nodejs repl

mousetail

I wonder if people can beat my py double quine: yq.mousetail.nl/3/python

RubenVerg

(that's a hint i guess)

emanresu A

@RubenVerg Not any more :p

RubenVerg

09:35

yes anymore

emanresu A

damnit

mousetail

@emanresuA Inside docker or inside bubblewrap? It shouldn't have internet access if I set it up right

RubenVerg

would be the same in the repl now

emanresu A

as in just being able to execute commands by changing the judge code

so no

mousetail

Ok cool, when I hear reverse shell I think nc | bash

RubenVerg

09:38

oh, thought i was doing something smart but the more intuitive one is as long

emanresu A

I have a 20 that breaks due to a bug in yq

RubenVerg

i suspect we're doing very different things

emanresu A

check discord

mousetail

I don't see anything in the discord?

emanresu A

talking to madeline

mousetail

09:43

Sorry

What's the bug?

emanresu A

Long enough output will just fail to format and get truncated e.g. console.log(URL+0)

mousetail

There is a limit on output length but it should be several thousand bytes

emanresu A

I'm fine with having an output length limit but the JSON sent to the frontend seems to be truncated and improperly parsed

mousetail

Ok thanks I'll look into it

github.com/mousetail/yq/issues/22

RubenVerg

does editing challenges leave the submissions (if they still pass)?

emanresu A

09:54

yes

RubenVerg

wanted to add "(got <>)" to the expected output (though it's a bit of a hack) to know how much more you can optimize

mousetail

There is no retesting implemented yet, it leaves submisions whether they pass or not

You can also add a new test instead of modifying the expected output

RubenVerg

putting the length in the output?

mousetail

Actually in this case putting got <> in the expected probably the best solution

RubenVerg

did the other one but got something wrong

i'll do that one instead

Q: Pickles with protons

I'm not really sure this should be a physics problem, but maybe it has some connection. People make pickles with acid, typically lactic acid or vinegar. It is suggested that the acid environment, or $H^+$ ions is vital. What if we shine a beam of protons onto the vegetables to provide $H^+$? Will...

Browser zoom is such a weird feature. On pretty much every website more complex than mfws, it either:
- is overriden to activate built-in zooming
- resizes text and nothing else
- breaks the entire website
- does nothing

I guess it's one of those legacy things like being able to print a HTML page, which I have done exactly once

lyxal

By site rules, is there any way to have a sbcs where the symbols are actually words?

So like instead of needing Unicode you could use multiple ascii characters to represent a single byte

E.g. A "find index of a in b" glyph might be find

And it'd still be a single byte

emanresu A

if you have an encoding for it then yes

lyxal

You'd need a set of 256 tokens and make sure that tokens not in the codepage errored

emanresu A

i.e. a mapping from it to bit strings

lyxal

22:10

The mapping isn't the problem, we already do that with Unicode glyphs

It's more "is it allowed to have sbcs characters that are more than one character"?

emanresu A

yes, any encoding's fine, as long as you have a mapping to strings of bits

lyxal

Even an encoding where the tokens aren't always the same?

(e.g. A literate mode with multiple aliases for functions)

emanresu A

Once again: Yes, as long as you have a well-defined mapping

I want to make a golfing language so bad sometimes but I know I don't have the time lol

I've had an idea for years about making one inspired by JS golfing, and how it makes heavy use of recursion

lyxal

@rydwolf that's what they don't tell you when you get started :p

very easy to underestimate the time needed to make a golflang outside of a novel toy project

also very easy to underestimate the scope and scale of making non-trivial modifications to an existing one too :p

Sometimes I wonder how I ever managed to do it myself

rydwolf

I've got a general idea for how long it takes 'cause of Ash

Ash would never have been deployable though, I found bugs in pretty much every operator I tested (typically niche stuff like NaN handling)

lyxal

23:50

It'd have become deployable over time

bug fixes arising from every-day golf usage would have stablised it

you might have even gotten someone come along, open a PR adding a whole bunch of test cases that reveal a whole bunch of hidden bugs, and then be able to patch them all over the course of multiple releases
