The Nineteenth Byte

CMC: restricted-source code-bowling Longest valid (runs without error, if an argument is required to run it, there must exist at least one value which makes it run without error) program/function consisting of characters that are consecutive in Unicode. Comments not allowed. E.g. !"#$%&'()* or ¡¢£¤¥¦§¨©ª«¬®¯ or ⌶⌷⌸⌹⌺⌻⌼

I just ran a random 47-char permutation rz;/.]8s9ye1vbw675puti\=lng4cx2`fqd,[ja'0h-mo3k in Jelly and got -1

pxeger

@Adám I presume it should be irreducible for whatever it does?

@pxeger No, [tag:code-bowling]

pxeger

But then I can do Zsh, ∞ bytes: <<<===================================================

Adám

Ah, that's a problem for languages that ignore unknown chars.

pxeger

with as many = as you like

(requires --noequals)

Adám

@pxeger Last I checked < and < occupied the same position in Unicode.

lyxal

@Adám Vyxal, 143778 characters

basically, everything after Q

including Q

Adám

8:15 AM

@lyxal Quit?

pxeger

@Adám oh, the whole thing has to be consecutive, not just contain them

lyxal

@Adám :)

wasif

@lyxal what does Q do

Adám

@lyxal I'd say that constitutes a comment.

pxeger

Do you mean syntactically valid, or does it have to produce no errors at all?

lyxal

8:16 AM

@Adám how about string literals?

Adám

@pxeger It has to be able to run.

wasif

@Adám Deadfish~ any 996 consecutive unicode chars

Q: Take the numbers 1 to 100, square them, and add all the even numbers while subtracting the odd ones

Description The task is simple enough: Take the numbers 1 to 100, square them, and add all the even numbers while subtracting the odd ones. It is taken from this blog post: R Coding Challenge: 7 (+1) Ways to Solve a Simple Puzzle Output The result should be 5050. Rules No cheating: it can be show...

Adám

@lyxal That's fine, but good luck finding an open-close pair that are far apart. And if you only open a string, and the rest of the program is then included in the string, then I'll call that a comment.

@wasif Why?

wasif

@Adám interpreter uses recursion

pxeger

8:17 AM

Zsh, 34 bytes: >?@AB..YZ[\]^_

lyxal

Vyxal, 143819 characters: everything after and including (

wasif

recursion depth will exceed if more than 996 chars given

lyxal

@lyxal because it opens a for loop which runs 0 times

no wait

oh frick

gosh dang ) being right next to (

pxeger

lmao

lyxal

okay then

@Adám Vyxal, 143768 characters: everything after [ (including [)

Adám

8:20 AM

@lyxal What does [ do?

pxeger

@pxeger forgot to mention it has to be with the -F option

felipa

I haven't got the time/energy to fix Pong but if anyone else could I would be infinitely grateful

lyxal

@Adám opens an if-statement

Adám

@lyxal So essentially, it is an if false?

lyxal

@Adám no, it's an if true

@felipa I might try to in a few days, it'll probably involve reading through all of the answers and trying to find a clear set of rules that invalidates as few as possible, which'll probably take a while :/

lyxal

@Adám it would need a | to be an if-false

PyGamer0

@Adám nothing for 51ac8 as $ dup top 2 stack; # is a comment

Adám

@lyxal Oh, so it gets stuck in an infinite loop at [\]?

lyxal

@Adám no

the \ escapes the ]

Adám

So what happens to the rest of the code?

lyxal

8:24 AM

@Adám because it's run on an empty input (which defaults to 0), it never actually executes the if statement

and if you call that a comment then I'm VTCing the CMC as unclear

Redwolf Programs

Where does the markdowning in question start?

lyxal

very cool

thank you

CMQ: Which is more useful when trying to treat an integer as a list: range(n) or list of digits of n?

pxeger

digits

lyxal

example: getting the permutations of an integer

Adám

8:27 AM

@lyxal The former.

Bubbler

Both are useful in different scenarios

Adám

@lyxal Maybe make negative integers do range, and positive ones do digits?

Works out nicely that 0 is both.

Bubbler

when the former makes it trivial (i.e. you can get the identical functionality from a different built-in with same bytecount), you can use the latter

I think that's how Jelly does, more or less

Unrelated String

jelly usually rangifies, but some builtins operate on the digits, and others even treat integers as singleton lists

and that's probably the thought process behind it

felipa

@RedwolfPrograms cool

@NewPosts 41, 42, 43 byter three python answers

we were so busy outgolfing each others

@lyxal digits

Vyxal has tons of range builtins

now i would count my esolang a code golfing language
