Quite a few programming languages have been made to specifically to facilitate code golfing, like GolfScript, Pyth, CJam, Retina, and Jelly. Other programming languages just naturally lend themselves to golfing, like the APL family of languages (J, K, etc. Well, really Jelly too.), and TI-Basic....

feersum

I guess, although no one other than me has ever attempted to use it.

Sp3000

Well if it's on TIO now, I guess you have more of a chance :P

Speaking of which, @Dennis Could you please add ><> to TIO? I feel like the current online interpreter has a few quirks which differ from the official one

Nathan Merrill

I actually think I understand why we are getting two different responses. On the "features we want" people are much more prone to upvote thinking "yeah, that sounds cool", where an actual meta post gets people actually considering the issue at hand

(though I may be biased in my assessment because I'm against it)

@NathanMerrill It's not perfect, but I took a stab at answering: meta.codegolf.stackexchange.com/a/8618/14215

@NathanMerrill I upvoted the first one, thinking "yes this is a difference from being a Q&A site", but on seeing the second one, the dedicated meta post, I can see why it's a bad idea and I would change my vote if the answer was edited.

Nathan Merrill

you would change your vote if what answer was edited?

oh are you prevented from changing on the Q&A site?

@IGoBest I disagree with your first point, agree with your second two, and you can add me to the list

@NathanMerrill Yes, but I imagine @AlexA. will be fine with an edit to allow vote changing. Does that sound reasonable Alex?

+1. And I'd like to change my vote on this proposal if it gets edited to allow it. — trichoplax 3 mins ago

Zgarb

@IGoBest Nitpick: my first post was a KOTH answer. ;) Still, +1, and I'm in the same situation as @trichoplax with respect to the earlier proposal.

trichoplax

I was initially in favour of this, but I have been dissuaded. I think finding 1 HelkaHomba level challenge writer is worth putting up with 100 new users with low quality first challenges. It's work for the community, but think of that work as mining for new challenge writers. — trichoplax 10 mins ago

@Zgarb Really? Your profile shows you asking two questions before the KotH answer. This one first: codegolf.stackexchange.com/q/41375/14215

I guess if it was deleted it wouldn't show, but then you wouldn't have had the rep to ask from a deleted one anyway if the requirement was there.

@trichoplax Then shouldn't you be "stackexchangetrichoplax"?

Geobits

You can also see me referred to as Generic Holiday Name in the winners section of this post for my answer there.

trichoplax

@HelkaHomba Lol no - my github username is just "phagocyte". It was already taken elsewhere so I ended up as githubphagocyte due to an imagination deficiency.

Helka Homba

Has anyone besides be really changed their name recently? (anagrams don't count)

Aww, I thought it was a phagocyte that had made its way into github to wreak havoc.

@HelkaHomba Lynn, lirtosiast, and someone else I can't remember.

@Geobits Oh - I thought lirtosiast was an anagram - I think I've just ended up assuming everyone that looks new is an anagram :(

Sp3000

It's an anagram for "soil artist"

Geobits

@trichoplax Yea. Just like that Ax Rip Cloth guy.

trichoplax

@Geobits This is one of the reasons I didn't like being githubphagocyte - it gave some people the impression of a creature that goes around github improving it like an immune system cell, and I couldn't claim to have done any such thing... That and I didn't want a brand name in my username.

The problem with short codes like that is that there's too many possibilities of attack. Probably needs a fair bit more ciphertext to be an interesting code to crack.

Yup. Renamed it to "BetterNumber" (because, you know, Abstract type java.lang.Number exists).

I'd probably stick with Number. Java itself has two List classes (java.util and java.awt), for instance, and I can't really think of a time when it caused problems.

As long as it's not in the java.lang package it should be fine.

Senior Prank We're graduating to a full site soon, and there's only one thing left to do before graduation: pull a senior prank! I think we should do a variation on the classic "fill a hallway with cups of water" gag. Challenge Your program will read in text and output that text, covered in up...

I'm having a bit of trouble with some CJam, can anyone with more experience than me spend a moment to tell me what I'm doing wrong?

Aqua Tart

Sure.

A Simmons

:C0]{_[W1].+}C* is a snippet that I think ought to work when an integer is the sole thing on the stack

http://cjam.aditsu.net/#code=5%3AC0%5D%7B_%5BW1%5D.%2B%7DC*ed

it takes 0 -> [0 0]

2-> [2 0] [1 1] [0 2]

etc, and you can test that this works

But it seems to fail completely if you wrap it in a code block and map it over an array; if you put a stack trace on you see that it's leaving the output on the stack like it was a fold

cjam.aditsu.net/…*%7D%25‌ed

links aren't working right.. :s

Aqua Tart

Can you give a TIO link instead?

A Simmons

17:40

Is that just how CJam does maps? Repeatedly pushes elements of arrays onto the same stack and then applies the codeblock?

Aqua Tart

Yeah.

A Simmons

Okay, fair enough. I was expecting it to have an effective fresh stack for each item in the map and then make the results into an array

Thanks for the help

Aqua Tart

np

Sp3000

Yeah, it doesn't do a fresh stack because sometimes you still want to access the array elements

Having said that, 5),W%eeWf% might be a bit easier

@Bigtoes Yes, but not input.

You can define a function that has a default parameter but it can't require the user to input anything more than what was specified.

@trichoplax ಠ_ಠ

RenderSettings

Oh, then I think this would actually count then.
Hoon has syntax for navigation of the context the function evaluates in. Pushing a variable on puts it at `-`

So |.(-) echos the input if you run it as =+(5 (f))

Might be considered too loopholey though :/

Easterly Irk

You can't enforce any rules about how your code has to be run except the ones that the challenge gives.

ie if it asks for a string you can't output a list with each letter in a element.

RenderSettings

Ok, that makes sense.

Sidenote, but Hoon actually has two string types :p One of them /is/ just a list of letters

Easterly Irk

@MartinBüttner If that existed, I'd think a BF interpreter in Retina would be simpler.

@Dennis It's probably just a beginner mistake. I am trying to make a verb s that's N s M = N - M + 1. I've got s =: -& (+&1), but this yields a regular subtraction.

Martin Büttner

yeah that's true, although it wouldn't be able to print without the program terminating

Martin Büttner

(I'm thinking about ways to print things that aren't the entire state as well)

mbomb007

@MartinBüttner Like specific capture groups?

Zgarb

@CᴏɴᴏʀO'Bʀɪᴇɴ Is that (N - M) + 1 or N - (M + 1)?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zgarb (N - M) + 1

Martin Büttner

@mbomb007 that's not a bad idea actually, I hadn't considered that

Zgarb

@CᴏɴᴏʀO'Bʀɪᴇɴ You should use @ instead of &: s =: (+&1)@-.

Martin Büttner

I want to add "forks" where you can perform different computations on the same string and then join them back together. that would allow for something like this, but I like your idea better

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zgarb What does @ do? I know @: is composition, but I haven't learned about @ yet.

Zgarb

19:23

The parens are also unnecessary, so that's s =: +&1@-

Dennis

@CᴏɴᴏʀO'Bʀɪᴇɴ The first problem is that J is parsed from right to left, so you're adding 1 to M before subtracting.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Dennis Oh, right. That's always confusing.

Martin Büttner

@CᴏɴᴏʀO'Bʀɪᴇɴ sorry totally overlooked that. but no I couldn't have helped.

Zgarb

@CᴏɴᴏʀO'Bʀɪᴇɴ @ is also composition, but has the level of the right argument. So if v threads over a list, then u@v threads too.

Dennis

@CᴏɴᴏʀO'Bʀɪᴇɴ The golfiest way would be 1+-

Zgarb

19:25

You can use s =: +&1@:- if you want, it makes no difference here.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@Zgarb Oh, I see.

@Dennis Is that a hook?

@MartinBüttner not a problem ^_^

Dennis

No, that's a fork.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Oops.

I love regex golf.
