You need Discord for that

@Downgoat Huh what. Just click continue to Discord. That'll open the web version.

Downgoat

ok it worked now

D: Safari is not supported discord browser ;_;

Leaky Nun

@Downgoat download it

Dennis

@Downgoat I tried 2&(**), not (**)&2. I'm not sure I understand why the latter replaces the left argument.

Downgoat

05:30

@Dennis because i can't figure out how to get former to work :|

Dennis

And how would you curry the right argument?

Downgoat

Cheddar checks LHS for what implementation of & to use. to curry right argument you'd use fn.curry (part of conor's un-merged functional library)

@LeakyNun nah. i like safari

Downgoat

05:53

question: do you think i can sneak stuff like exponentiation, binary operators, etc. under "arithmetic"?

Leaky Nun

@Downgoat there's a thing called binary arithmetic

and ofc exponentiation is arithmetic

Downgoat

ok, i guess it'll work

wikipedia says arithematic is just + - * and /

So I use GitBooks for writing Cheddar docs. Turn out pasting is borked in Gitbooks...

Let's see if the meme speaks the truth.

Q: Write a VIC cipher encoder

The VIC cipher is one of the most complicated pencil and paper ciphers ever devised. Used in the 1950s by Soviet spy Reino Häyhänen, codenamed "VICTOR", its main principle is security through obfuscation; a lot of obfuscation. Your task is to write a program or function that will take a message ...

Q: Write a VIC cipher decoder

You've received a coded message from your ally that you know is encoded with the VIC cipher. As you know that the VIC cipher is notoriously convoluted, you want to write a program that will decode the VIC cipher but is small enough to hide from the enemy if you are captured, and thus uses as few ...

@Dennis What was your answer?

miles

no don't give it away yet

Dennis

@Adnan Python 3.4 and 3.5 are different languages for your challenge. Does that mean the same sequence can be used for both? What about Jelly and M? M is essentially an early version of Jelly with symbolic math instead of floating point.

Leaky Nun

@Dennis Should I delete my answer until I can find a 6-byte answer?

Dennis

No, a crack is a crack.

Adnan

@Dennis Technically yes

Leaky Nun

06:49

@Dennis Good news then

Dennis

@Adnan That makes the rule forbidding multiple answers kinda pointless, don't you think? Python 2.7 has 10 subversions, Python 3 has 6, etc.

Adnan

Oh, do you think I should also disallow answers in both Python 2.x and Python 3.x?

Dennis

Depends. What are you trying to prevent with that rule?

Adnan

Nevermind

Dennis

@Adnan I'm not sure how you're drawing the line there. It's clear enough for Python, but what versions are different for Julia, Java or C?

Adnan

07:03

Yeah, that was what I was afraid of.

Maybe I should disallow all versions then

Dennis

What are you trying to prevent? Leaky Nun found a 10 byte crack to my 11 byte submission, but I can go lower. What harm would come from posting a shorter Jelly answer so the robbers could try again to outgolf me?

@Adnan Even then, M would still be allowed because it's a different language.

Destructible Watermelon

well, perhaps the idea is that if you post the larger source code, you get more points for more risk? (no risk if you could repost lower)

Adnan

That would be allowed, just not Python 3 and Python 2

Since they are the same language

Dennis

@DestructibleWatermelon There is a risk, because robbers get more time to work on their cracks. Also, it's not like I had a 10 byte answer myswlf (not counting adding no-ops to my shorter solution).

Destructible Watermelon

@Dennis well, that could be circumvented by posting all at same time, no?

Dennis

07:10

OK, yes. Allowing different posts in the same language at the same time should't be allowed.

@NewMainPosts nooooo, i missed it ._.

@TùxCräftîñg exempt

TùxCräftîñg

i am trying with backrefs but i just have created a unreadeable regex

(and it dont work D:)

i am stupid

Destructible Watermelon

@tux, that's not necessarily true

TùxCräftîñg

my regex is (\({2,})(.*?)\1

Destructible Watermelon

I don't know regex much

I know a bit though

TùxCräftîñg

this match ((((, not (())

Destructible Watermelon

08:25

doesn't * mean 0 or more?

why do you also have a question mark then?

TùxCräftîñg

yes

so the pattern is lazy, it will stop at the first occurence

otherwise the pattern is greedy, it will stop at the last occurence

Destructible Watermelon

shouldn't it be (.?)* then (still no expert though)?

TùxCräftîñg

no

? is a quantifier modifier

Destructible Watermelon

won't .*? just have no .* or a greedy .*

?

.* is greedy, so if you have .*?, it just means 0 or 1 greedy things

TùxCräftîñg

no

Destructible Watermelon

08:28

how does it work then?

TùxCräftîñg

idk how the regex parser internally work, but i think when the parser encounter a quantifier, it check for a ?. if there is a ?, the quantifier is lazy, otherwise greedy

Destructible Watermelon

if you don't know, have you tried it?

TùxCräftîñg

i have tried it

example:

".*" will match "a" "b" in "a" "b", but ".*?" will match "a" and "b"

Destructible Watermelon

what will (.?)* match?

TùxCräftîñg

"a" "b"

Destructible Watermelon

08:31

where is the part that matches ) in that regex anyway

TùxCräftîñg

nowhere

Destructible Watermelon

is the \({2,} greedy?

TùxCräftîñg

i tried to use backrefs but i just messed up my regex

@DestructibleWatermelon yes, but since i only want to match (, there is no need to make it lazy

the only need for a lazy regex is with .

Destructible Watermelon

oh right

I get it now

TùxCräftîñg

regex101.com

cool site to regex

Destructible Watermelon

08:34

why \1?

TùxCräftîñg

\1 match the first capturing group

so if the first capturing group match hi, \1 will match hi

Destructible Watermelon

instead of how you want it ( ((string matches)) )

it does ((string matches((

TùxCräftîñg

exactly

I don't see how there is an issue to fix without just trying again

in my example code: so, the pointer starts at . the pointer looks around the surrounding 8 squares, sees F, transfers control to other F, Pointer looks around F, sees 4 and 3, pushes them, sees S, goes to it, sees +, adds 3 and 4, sees 4, pushes 4, sees multiply, multiplies 7 (on stack) and 4
