also does dashes mean the total amount of dashes in the leftmost column or just the top part?

TheBitByte

@Downgoat Just the top part.

The part with |

Downgoat

ok, can you clarify that in the challenge

TheBitByte

ok

xnor

can we please just insist that BitByte move this to the Sandbox and we can offer suggestions there?

i understand we're trying to be helpful, but I think at this point helping fix the challenge after it was posted like this will encourage them to not use the Sandbox in the future

@ReleasingHeliumNuclei Yes. Hopefully I've fixed everything there is to do with the question. Now I just need 5 reopen votes. Anybody?

Syxer

Sandbox is nice because you don't actually lose anything (rep/deletion/closevote-wise).

Plus, if a challenge comes out of the sandbox, it's really ready, not just the understanding of the writer.

DJMcMayhem

@TheBitByte One thing is still unclear to me. Is the second parameter the width or the area? How do we know how tall the box should be?

TheBitByte

12:24 AM

@DJMcMayhem Width.

DJMcMayhem

That still doesn't answer the second question.

TheBitByte

I don't understand the second question.

DJMcMayhem

How tall should the box (not the tall column) be?

Downgoat

@TheBitByte I think he's reffering to the box with the spaces. what should the height of that be

DJMcMayhem

Yes, that

TheBitByte

12:27 AM

The height is as the question shows it to be. Don't change it. The question itself also says this:

> "With the exception of the number of spaces (i.e width) in the box shape & the number of `|` in the top tall line , you must keep everything else in the ASCII art as it is."

@TheBitByte that is still inferred from your (very few) examples. At any rate, I don't feel like arguing with you anymore, since many users have given you very helpful advice, not just on this challenge, but on challenge writing in general (use the sandbox!) and you only respond with antagonizing.

TheBitByte

@Downgoat In its current state, the question looks fine to me. If you have constructive criticism that isn't nitpicking, then go ahead.

quartata

We wouldn't have to be beating you over the head with these problems if we could work with you in the sandbox and not have to deal with this on main

Sp3000

@TheBitByte I haven't read any of the previous conversation, but based on me just reading the spec right now I've got two comments: 1) I can't tell whether I'm only meant to output 1 box + tall line (b-shape) or multiple depending on some input, and 2) I can't tell whether the height of the box is meant to be exactly 7 characters or whether they're affected by any of the inputs (as in, whether the "number of | in the top tall line" refers to only the part above the box or not)

Downgoat

@Mego I'm planning to have "lazy expression blocks". You'll be able to write up a value as usual, perform operations and all, but it wouldn't be evaluated until it really needs too. This will be helpful so, for example, reciprocal(1 / 3) would output 3 rather than 2.9999997

Anonymous

@Downgoat And what do you mean by algebraic blocks?

Anonymous

(PS I like the idea of lazy blocks)

Downgoat

i specify an algebric equation: e.g. reciprocal($x=1/3$). lazy blocks seem like a good fit for algebra so I could easily implement algebra stuff in them. Downside is they'd then be considered algebraic blocks rather than lazy blocks because then syntax would be different from regular expressoins

shinh's implementation does some optimisation, although from a quick look, i think it looks for -1 in loops, so it will optimise [>++<-] but not [>+++<++] for example

i don't know that speed is very important, but i suppose if you can make it faster without introducing bugs or exploits then why not

DJMcMayhem

Urgh. Why is it so hard to convert a code-point into a unicode char in ruby? puts [256].pack("U*").encode("utf-8") just feels wrong

Mitch Schwartz

i originally thought of bff since it has most of the same implementation details as BFI but without the exploits, so most of my non-cheat code would work as-is

but after talking about it, 8-bit seems better

@TheBitByte ... "A fragile quine is a quine that satisfies the property of having each substring made by removing a single character, when evaluated, produces an error."

TheBitByte

@ConorO'Brien Does that include quines that aren't fragile on purpose? If so, then it's a pretty trivial challenge.

Conor O'Brien

Anyone else have useful feedback that actually read the challenge?

TheBitByte

I did read it, but it needs improving to be less easy.

primo

2:09 AM

basically, it's the most flexible, if you need a 0 or -1, just prepend [-] or [-]- to the read

TheBitByte

Imagine I have code `print ('foo')`

Removing one character and doing `rint('foo') isn't going to work, however, my error isn't on purpose. I could keep trying to remove each character and test if it gives errors. It might. But then, it gave an error because the code itself was wrong, not that I actually bothered to make it "fragile" on purpose at all.

@EᴀsᴛᴇʀʟʏIʀᴋ Thirst starts at 500 and every tick it decreases by abs(tan(u.uthirst)), which gives it cycles of more/less water loss. Drinkng any uncursed potion gives 250 hydration, eatng any vegetable gives 50 hydration. Dipping below 100 hydration gives you a status message and dipping below 0 slows you and gives you 25+Constitution turns to live. When you drink a potion of unfiltered water (#dip an empty bottle into any water source) it has 1/7 chance of giving you dysentery (vomiting slowed) but applying a water filter purifies it. Quaffing from a transpiration bag gives you turns since…

TheBitByte

@quartata Sort of idea what that means, but it's interesting.

Conor O'Brien

@TheBitByte Let me use simple words. When I mean each substring has to error, I mean that every single possible substring made by removing a single character has to error. If you ahd print("foo"), then there is a substring (e.g. print("fo")) that doesn't produce an error. So it is not fragile.

quartata

2:18 AM

That's because you don't know the context :P

TheBitByte

@ConorO'Brien Okay, now I get it! Your challenge now looks more interesting, to be honest.

Conor O'Brien

great, glad we got that cleared.

was that not clear from the challenge, or did you just miss something in the challenge?

TheBitByte

It wasn't clear from the challenge at first.

Conor O'Brien

So what would you suggest I add to make it clearer?

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ All clear?

TheBitByte

2:23 AM

Add something along the lines of:

"For example, if your program is `print('foo')`, then, you remove a letter from the code, the code must produce an error. This has to work with all possible combinations of removed letters, and you must remove only a single letter. Code that would normally be correct when a character is removed must still produce an error. In the earlier example, removing a letter and doing `print ('fo')` still works, however, under the rules of this challenge, it shouldn't."

@DJMcMayhem I can play for 20-30 minutes, that good for you?

DJMcMayhem

Yeah, that sounds great

Conor O'Brien

@TheBitByte Cool, will do. And will look!

TheBitByte

@ConorO'Brien Thanks!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata what about cursed/blessed potions? and are water filters like tin openers?

Conor O'Brien

2:24 AM

@TheBitByte you might want to include examples about inputs that don't have 7,2,

Mitch Schwartz

@primo i'd seen that before, but it still seems strange to me, like if c = getchar()were to leave c unchanged on EOF -- is that really in line with what programmers will want to use it for? and i'm not convinced that there's value in the ability to simulate both EOF = 0 and EOF = -1, you can just write code that is designed for one or the other.

-1 makes sense to me for more than 8 bits; you have a value that is not in [0,255], so you can process any binary data. For 8 bits, 0 is as good as -1 so you might as well use 0, unless you want to be able to handle \x00 in input and not \xff for some reason

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem rebooting steam, it's laggy

DJMcMayhem

^^^ Also, I noticed you forgot to update the example input, so half of them still say 7.

Conor O'Brien

@TheBitByte Other than that, it looks good!

Mitch Schwartz

but it's possible that i'm just not thinking clearly

TheBitByte

2:25 AM

@ConorO'Brien Done. Check my edit.

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ Blessed potions give the same amount (except for holy water which gives 500). cursed potions make you lose 50

Eᴀsᴛᴇʀʟʏ Iʀᴋ

okay, cool

DJMcMayhem

Do you know if it's possible to sort all my starred message by number of stars?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata and water filters act like tin openers? With charges like that?

@DJMcMayhem ready to play

quartata

Yes.

DJMcMayhem

2:26 AM

Yup

Just hopping on now

Eᴀsᴛᴇʀʟʏ Iʀᴋ

kk

TheBitByte

@EᴀsᴛᴇʀʟʏIʀᴋ What rep do I need to be able to suggest edits to people's posts?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@quartata do camel packs wear out?

@TheBitByte idk, i think 1k or something

TheBitByte

@EᴀsᴛᴇʀʟʏIʀᴋ That's a bit too much in my case haha.

quartata

No.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:27 AM

okay

TheBitByte

Then what is it?

Eᴀsᴛᴇʀʟʏ Iʀᴋ

he was replying to my message about camel packs

Conor O'Brien

@TheBitByte looks good!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@TheBitByte you can't edit on meta until you have 1k rep.

primo

@MitchSchwartz say you were a 'serious' brainfuck programmer, if such a thing can be said to exist. your preferred interpreter uses EOF=0, however someone you're collaborating with uses EOF=-1

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:28 AM

it's 2 messages, give me a sec

You can always suggest edits on main, but they wait for a review before posting. No review needed > 1k rep.

primo

the easiest situation for both of you would be to use an interpreter that ignores EOF, and prepend [-] and [-]- before each ,

TheBitByte

@EᴀsᴛᴇʀʟʏIʀᴋ Thanks!

DJMcMayhem

@EᴀsᴛᴇʀʟʏIʀᴋ it'll be 2k in 6-8 weeks

TheBitByte

@primo Tag the people in question so they can see this.

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@DJMcMayhem oh, okay >_>

primo

2:29 AM

but yeah, for golfing, whenever it does make a difference, EOF=0 will likely be the shortest

TheBitByte

@DJMcMayhem Why?

Got a link to meta.SE?

primo

@TheBitByte i tagged him on the first response, which should be sufficient

TheBitByte

@primo I don't think so, since you have to scroll up far to see the first response.

primo

it's still on this page...

Mitch Schwartz

ok, i see your point. well, "better for golf" appeals to me more than "better for writing cross-implementation code" :)

DJMcMayhem

2:31 AM

@TheBitByte because of graduation

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@TheBitByte graduation increases rep privledges limits

Which esolangs look the least like esolangs? i.e. you could easily confuse a program written in it for a program written in a non-esoteric programming language

Conor O'Brien

@StevenH. codename dragon

quartata

@Doorknob How many ioun stones do you think I should let a player wear at a time

Steven H.

2:34 AM

Without comments, so no Whitespace

Conor O'Brien

or maybe INTERCAL

esolangs.org/wiki/INTERCAL

Steven H.

Is Cheddar close enough to an esolang to be considered esoteric?

Conor O'Brien

it's supposed to be for regular programming >_>

quartata

Definitely not

Eᴀsᴛᴇʀʟʏ Iʀᴋ

@StevenH. no

@quartata ioun stones?

Steven H.

2:40 AM

Well that settles that

quartata

Gems that circle around your head and give powers like rings

Conor O'Brien

night y'all

Steven H.

What game is this @quartata

quartata

I'm making a Nethack fork

TheBitByte

Looking for a final review to my sandbox puzzle (http://meta.codegolf.stackexchange.com/a/9960/58717)

Thanks!

Eᴀsᴛᴇʀʟʏ Iʀᴋ

2:45 AM

@quartata ooh

@quartata oh, from pathfinder?

Lynn

I golfed some Perl:

0

A: End the tabs versus space war

Perl, 41 bytes s,␉, ,g;s,^ ( +),/@{[$1=~y| |*|r]}/, Run with the -p flag, like so: perl -pe 's,␉, ,g;s,^ ( +),/@{[$1=~y| |*|r]}/,' # ↑ └───────────────────┬───────────────────┘ # 1 byte 40 bytes Replace ␉ by a tab (in Bash, try typing Control-V Tab.)

I’d love feedback from people who actually know their Perl golfs!

Steven H.

@quartata one of each type up to three?

Lynn

Oh, I see @primo is here~

quartata

@EᴀsᴛᴇʀʟʏIʀᴋ They're from Dying Earth (great books by the way). They were stolen from it sometime around ADND I think

Mitch Schwartz

btw idk who starred that message, not that it's a bad message or anything

TheBitByte

2:57 AM

@quartata Can you do me a favor? My challenge (link above), I just wanna check the examples are right and the inputs in the correct order, to not miss anything. I've already done this but I'm worried a bit. Could you help? Thanks!
