@CᴏɴᴏʀO'Bʀɪᴇɴ Yes it is :)

@CᴏɴᴏʀO'Bʀɪᴇɴ Cops and robbers are always fun :-)

yeah :D

I'm planning on having the most cops submissions >:|

@LuisMendo I thought your submission would be very easy

Until I saw the 5

:(

@Adnan Haha. I'm glad it's not

I'm taking a look at yours now

The rules say I can hide all my characters, right?

@LuisMendo Good luck :)

@CᴏɴᴏʀO'Bʀɪᴇɴ Yes, but then you are restricting less the set of possible alternative codes

True. I ask because I have a four-byte program that would be discovered easily if I had shown any of the four :P

maybe time to obsfucate XD

@Adnan Cracked!

Nice! That was the right answer :)

Realized that I used range twice :p

Hahaha, the second inclusive range was a no-op though :p

what does "intolerant towards 0" mean?

^

I think it has something to do whether your code works for a(0)

But I'm not sure

for the cops n robbers, wouldn't cops simply want to post the sequence?

I mean, it makes it harder for the robbers to crack

I don't understand this challenge

"The cop can hide as many characters as is so wished."

So why do people even show any character of their code

But that means that there are more possible codes that also work for that sequence

if it's not very long I doubt there are many ways to do the same thing

Yes, for like 4-byte answers, that might be the best strategy

It's actually a neat system: if you hide all the characters in a 100-byte program, then someone could easily outgolf your original submission/find a different OEIS that's easier to implement

@NathanMerrill I understand that as: 0 produces an output (tolerant) or an error (intolerant)

@Adnan I knew there was a range involved. But I couldn't even find the function :-P

@LuisMendo Hahaha, it's a long list :p

Huh. L doesn't contain the word "range" in its description. That's why couldn't find it!

Yeah, ranges are explained with [...]

I think it's interesting to see what people are attempting for my entry for the C&R

I just have the server print out the code that's sent to it before executing it

It's also telling me what to document more

like R0 is effectively a noop. They probably wanted to do R 0

Hello back

@muddyfish o/

lol

Hahahaha

HELLOOOOO MUDDYFISH!!!!! - nice code btw

yes sorry

I should make it so it logs your IP too ;)

plot twist, it already does

3 upvotes, unknown time. _UNK / 3 = _UNK

@Doorknob Why do you use Doorknob here and KeyboardFire everywhere else?

R1 is effectively a noop too but it makes sure at least one item is on the stack

@muddyfish It has something to do with primes, doesn't it

R by itself is the same as R2

might do

@quartata inertia ¯\_(ツ)_/¯

I can't just change it now

I was under the impression that KeyboardFire came first

before Doorknob of Snow

should Cheddar use for a of b or for a in b?

@Downgoat Neither; for a (b)

for a in b

@quartata wat.

(I'm a pythonny person)

@quartata no, it didn't

@Downgoat for variable (array)

It was much later

@Doorknob oh, huh

@quartata I have never seen that syntax before...

@Downgoat Really?

That surprises me.

I won't tell you what language it's from because that'll bias you against it, but suffice to say it's pretty common.

I like it

@Adnan 2 1R is the same as 1 2

That's not me :p

isn't it?

ok

@quartata isn't that how BATCH does it?

@CᴏɴᴏʀO'Bʀɪᴇɴ Maybe, I don't know.

Or is that a loop with steps

@zyabin101 :D

^^

why do I know that

@person sorry I broke it for a second

Hahaha

@quartata Python I have no idea

@Downgoat No, Python does for a in b

@zyabin101 That's because Linux actually works

@zyabin101 :D

@quartata not for me

@Downgoat OK, all right. It comes from Perl.

But that doesn't change the fact that it's a good idea

I kinda like perl :P

perlfect

@quartata hm, but there is no keyword...

@Downgoat It doesn't need one.

for $a (@b) { ... } is how it looks in Perl.

strawpoll.me/7324370

for a of b is just weird.

JavaScript does it....

If you're gonna do it like that you might as well do for a in b

@Downgoat I'm not going to warrant that with a reply

@quartata cough cough my

@Doorknob Oh shush

@quartata that wasn't a justification for it's non-weirdness :P

for(a : b) à la Java

@Fatalize Oh, that's nice too.

@quartata call-with-values is a counter-intuitive function to use. Most people prefer to use let-values or receive instead. The correct invocation for your case, with call-with-values, is (call-with-values (lambda () (partition even? (range 1 5))) (lambda (x y) (map + x y))) (or, golfing with SRFI 26 like I did, (call-with-values (cut partition even? (range 1 5)) (cut map + <...>))).

@Fatalize I think I'll do for in, because it's easy to parse...

@ChrisJester-Young yikes

that syntax will mess up with typing

"for a of b" sounds terrible

^

of just doesn't sound right at all.

^^

@quartata The let-values version looks like: (let-values ([(evens odds) (partition even? (range 1 5))]) (map + evens odds)). Easier to read.

That sounds better, yeah.

Anyways, if I can map cons over it and flatten it I can just iterate through

Are you sure you're mapping cons and not list?

Oh, hrmm

Also, instead of map + flatten, use append-map.

oh, even better

append-map is known as flatmap in other languages.

@CoolestVeto iapologizetou

sowee

@LegionMammal978 That was from an actual website. I was reading a webcomic, and I tried to find the previous one by editing the URL...

@quartata and in fact, the solution I sent you did indeed use append-map. :-)

Wait, which one? I didn't see that.

Was that the golfed one?

Yes.

I can write you the non-golfed version of that code.

Ah, OK.

@EᴀsᴛᴇʀʟʏIʀᴋ <3

Also: I just named a class Object in Java. I regret everything.

@CoolestVeto I named a class Class in a project

HAI

HOI

HUI

HII

@CoolestVeto oh do NOT do that

@CoolestVeto you should name a variable undefined in JavaScript, that's the worst..
