The Nineteenth Byte

@quartata I said +1 in the comment, but didn't +1 it. XD Fixed.

Oh, didn't see the restriction to ASCII @quartata; my answer is invalid then

Two people pointed out a problem with my challenge, I edited, and then they promptly deleted their comments. Such a well-behaved community

Q: Longest Common Prefix of 2 Strings

5:07 PM

@ThomasKwa Was it a TI-BASIC one?

It wasn't really a restriction to ASCII per se

New Main Posts

Write a program that takes 2 strings as input, and returns the longest common prefix. Test Case 1: "global" , "glossary" "glo" Test Case 2: "department" , "depart" "depart" Test Case 3: "glove", "dove" ""

Just a restriction to the appropriate character encoding

No, it wasn't TI BASIC

alephalpha

I just solved Project Euler problems 2 using Hexagony.

I don't like that restriction; shouldn't the most natural representation of 1 in a language be allowed?

5:10 PM

What is the language?

oh god, all my addons broke with this latest firefox update...

I mean if it outputs as a 0 or a 1 it is OK is the idea. Not like outputting an unprintable that corresponds to 1 in you character encoding

Motorola MC14500B machine code

Takes I/O as bits

Ah I see the issue.

I took the better part of a day finding the language.

wow, histocrat's Ruby truth machine is incredibly clever

@SuperJedi224 thanks for fixing my terrible explanation

@VoteToClose Yeah, don't feel like you need to hurry. I'm pretty sure I've still got the simulators on my laptop at home, along with whatever .schematic files I've made.

Shady As Fuck, 2 bytes KX K reads one char and opens a new loop, X outputs the content of the current memory cell and closes the loop. The loop is running as long the current memory cell is not 0 (at the closing of the loop).

@CᴏɴᴏʀO'Bʀɪᴇɴ We got rekt

Although wait a second

I don't think that works the way he thinks it does.

I think it outputs bytes.

@quartata I think my answer is valid even as ASCII, after some more reflection

No wait

5:42 PM

@mbomb007 I'm not sure what your comment is getting at. What I mean in the post is that if we represent the 5xinstrument bits by replacing the opaque block by 5 separate blocks, then we can fit the note block into the encoding fine

@Sp3000 You say "I'm not going to address the total scoring method in this post, but I'd like to propose a method of counting each individual block.", but then what is the entropy for?

Is it just showing that each block can be counted as one byte?

Yeah, e.g. if you wanted to represent each block is a code-like format (like the new row/new layer idea I mentioned in the comments)

It's meant to be used with some other total scoring method, e.g. for volume you'd count each block as one then add on extra bytes for command/containers as necessary

@Sp3000 How dense are redstone constructions normally? Might a sparse encoding be more efficient?

That... really depends, and would probably go into GolfCraft territory where there's instructions to specify long segments of straight wire

oh okay

5:56 PM

Optimally I'd like to score it like TIS in that you can take a source code sort of representation and use it, but Minecraft being Minecraft it'd be hard to score (since you can't examine layer by layer easily)

@quartata can I get a ruling on my answer?

@Sp3000 That's why you'd post an image representation of a .schematic file. It's much easier to see it that way as it's 2D and visually similar to its appearance in Minecraft.

I remember some discussion going around a challenge involving as many loopholes as possible!

@Sp3000 static.inky.ws/image/478/image.jpg

There are also .gifs for multiple layers.

Yeah, but even with the schematic it'd be difficult to do what I had in mind, which was to treat it similarly to regular code

e.g. for the first row it'd be 8 bytes for air, 2 bytes for wire then a newline

6:00 PM

@ThomasKwa Is outputting to the data bus of a microprocessor an acceptable alternative to STDOUT?

@Sp3000 But there's no interpreter for that sort of code. You can score it that way, but I definitely wouldn't represent it that way. Plus, a .schematic file can be imported to Minecraft, so it makes sense to include one.

Q: Hello, World with loopholes

@quartata Yes; it's the only possible way to output.

Your task is to print Hello, World! breaking as many standard loopholes as possible. The score is bytecount/number of broken standard loopholes. GO!

code-golf

I actually did have the idea written down to create a language that is interpreted as if it was blocks in Minecraft, though.

office 365 is so buggy when it comes to logging in and out...

6:03 PM

I guess it is OK then. It's such an edge case I'm not sure how to rule it really.

Well I was just proposing a representation which is supposed to be better than using volume

It told me that my session expired, then told me that after I signed out, I needed to close all of my browser windows

Not that I'd use it though, which is why I haven't actually added it to my post

Scoring by volume would be the easiest to do, but like Piet it runs into a little issue which is encoding the dimensions

I guess going by the .schematic size is another option

Another bug not even 30 seconds later: i.imgur.com/zFSosdk.png

You answer, then ask for it to be closed?

you'd better delete your answer before any more downvotes

It was mostly to demonstrate why it was a bad challenge.

Is there a rep cap for downvotes? We should try to find out.

I'm not sure why it got downvoted anyways when it was really a fault in the challenge.

@feersum Oh shush

I deleted it anyways.

Yeah, I didn't downvote; if there's a trivial answer to the question it's not a bad answer

The question was so flawed in this case that you should have just posted as a comment, though.

@quartata Triple checking - STDERR output okay?

@Sp3000 STDERR output is fine

Outputting the actual output on stderr, or emitting error messages?

6:35 PM

@feersum I assume he means emitting error messages

@Sp3000 That is very well researched. +1

Error messages yeah

Outputting on STDERR is not OK (although I have no idea how you would pull that off and have it be shorter than STDOUT)

@anOKsquirrel esolangs.org/wiki/Category:Brainfuck_derivatives

@VoteToClose Yeah, it was kinda a response to your post. Having said that, your post doesn't really address how blocks are positioned relative to one another, which might be a problem

6:36 PM

Or here

I think someone has implemented an esolang at least once where stderr is used for stdout.

A: What are programming languages?

26

My previous answer was criticised for not drawing a line in a sand, so following some discussion on chat I propose a line. Executive Summary A purported programming language should be accepted as such if and only if it is capable of addition of natural numbers and primality testing of natural n...

@Sp3000 Hmm. I was considering direction - but given that MC inventions will vastly outsize other programming languages anyway due to the physical aspect of them, I figured it was better balanced.

TLDR: If you can add numbers, tell whether a number is prime and do I/O you're OK

Also, if we're including command blocks, it should be the bytes within and mobs used - I can make a calculator with 5 command blocks, a redstone block and an armor stand.

6:39 PM

I'm not sure we should balance just because a language is usually going to be very long...

So if the Befunge is 6 chars the Seed is possible to generate.

@ΚριτικσιΛίθος The fact that carrot is tied with Vitsy in the "showcase your language" page is telling.

@VoteToClose "and mobs used"?

Yeah - tracing statistics with /scoreboard for mobs is a thing.

If we're including mobs, that's going to be a whole new can of worms o_O

6:43 PM

For example - /scoreboard objectives set value JOHN @e[type=ArmorStand,c=1]

Mobs would essentially be stacks.

Yeah, but they could be used for other things too, e.g. pressure plates

How should I handle people posting answers that are longer than already-posted answers in the same language?

@quartata Of all the mainstream languages that could be expected to be popular for golfing, you might think Perl would be the top, but apparently not.

@quartata by the way, did you mean that any language that doesn't have STDIN can hardcode, or that any language that doesn't have a standard input method?

So it can't do any of the applicable input methods from the meta post

@trichoplax It's because most people aren't fluent in Klingon

@Mego If you think Perl is nasty you've never actually tried it

Anonymous

@VoteToClose It reads integer, list, or string input, depending on how the input is formatted. 1 is integer, "foo" is string, [1,2,"fizz",4,"buzz"] is list

6:52 PM

@Sp3000 No, I think it is fine if I leave that up to the poster.

They'll have to show where to put input anyways.

Is there any way to force input type?

So they'll more or less be posting both programs.
