A: When does /tmp get cleared?

That depends on your distribution. On some system, it's deleted only when booted, others have cronjobs running deleting items older than n hours. On Debian-like systems: on boot (the rules are defined in /etc/default/rcS). On RedHat-like systems: by age (RHEL6 it was /etc/cron.daily/tmpwatch ; ...

Could the Unlimited scrollback option be the culprit?

Almost certainly

Dennis

It writes scrollback to disk and deletes it on a clean exit. Yeah, that doesn't sound good.

Q: Answers still marked as "non-competing"

The community has decided that answers in newer languages can now compete in code-golf (they were previously required to be marked as non-competing). However, now and then I will still come across an answer that hasn't been updated with this rule yet, so it is still marked as non-competing. I ha...

Pavel

@Dennis Acting up how? For me the file selector dialog infrequently just stops being able to do anything.

H.PWiz

@ngn vim-apl. As in evaluate a line without having to move windows and copy line over

ASCII-only

@H.PWiz but you can execute shell commands directly from vim

Dennis

@Pavel Sometimes KDE things just... stalled. Killing kded4 and restarting it solved the issue temporarily, so I had been running a script to do just that every hour.

ngn

@H.PWiz well, for a repl i personally use the interpreter's own repl, but other people have tried to do what you describe github.com/baruchel/vim-notebook

H.PWiz

12:25 AM

I find that I need to use the repl a lot when writing any APL (most likely due to being a beginner)

@H.PWiz i've set up <cr> (i.e. the enter key) to execute the current file

H.PWiz

@ngn Execute the file?

@H.PWiz yeah, you know, chmod +x it and run it like ./filename.whatever

H.PWiz

Is that with your #! stuff that you mentioned in the other chat room then?

@H.PWiz it's very similar to a repl that way and i can use decent text editing

I'm trying to compile a list of neat ideas that esolangs have put forth but that can be easily explained. I want to present kind of a "best of esolangs" to my coworkers... Any suggestions for specific languages to talk about? So far, I'm planning to bring up Hexagony, Jelly, and Brainflak (as examples of languages that are designed to be hard to program in, golfing languages, and turing tarpits respectively)

ngn

12:30 AM

@H.PWiz lately i've had ideas for a vim shortcut that prepares a tio url and opens it in a browser, but my laziness always takes over :)

Οurous

@StevenH. Befunge, or another 2D language.

Where, unlike hexagony, it isn't brutal.

Conor O'Brien

@DJMcMayhem In brainflak, how might I duplicate the top 3 members of the current stack? I have a method but its not terribly golfy

ngn

@H.PWiz just to be clear: my <cr> shortcut is not in that repo, it's in my private vim config

Steven H.

Befunge is a good idea, I'll definitely do that

H.PWiz

@ngn I understood that, thanks

DJMcMayhem

@ConorO'Brien This is the first thing I could think of (52 bytes): Try it online!

@StevenH. I'm honored that you would include brain-flak in a list of best of esolangs :)

One good thing to touch on while explaining it is how it's surprisingly terse and powerful at certain things (esp polygonal numbers)

Destructible Lemon

@StevenH. ><>

i believe there's an article on the codegolf medium page about it as well

@DJMcMayhem I was thinking about how it's sort of lisp-like in some ways, and that gives me an idea

btw not just because of the brackets

basically replace the brackets with words in parentheses

for example (...) becomes push(...) or (push ...)

or (push-sum ...)

and it would sort of look like a weird use of a practical language or something

Destructible Lemon

2:01 AM

it definitely depends on what your definition of tarpit is

Steven H.

ps not very 3d

this is going to be a block in the game

Οurous

Literally that picture?

Destructible Lemon

yes

freehand, babyYyyyy!

i made it transparent though

so that's not an issue

ASCII-only

ok?

@DestructibleLemon ... cylinders don't lag out unless you mess up bad

Οurous

So far the game sounds horrible, anything else notable other than free-hand MS Paint polygon-sprites?

Gameplay? Intent? Reason for making it?

Destructible Lemon

crappy military perspective forever

Οurous

3:07 AM

It's very different if, say, it's for learning purposes than if you're going to try to sell it.

Destructible Lemon

or at least an attempt at military perspective

Οurous

@DestructibleLemon would be better if the edges at least tessellated.

Destructible Lemon

@Οurous people can sell things with poor graphics, if you consider pixel graphics to be poor graphics which it isn't really in most senses of the word poor, but you know what i mean

@Οurous a e s t h e t i c

i hand drew the thing on purpose

Οurous

@DestructibleLemon absolutely. But it just means that people probably won't buy it for the eye-candy, and so there's one less potential selling point. Hence I asked about the other attributes.

Destructible Lemon

it'll be free

ok so, everything is blue line art.

anyone wanna help out with the grafics?

ok so the idea is you can move either up-right or up-left each step, or do some sort of attack

that's the vague idea

ASCII-only

3:11 AM

@DestructibleLemon it's blue line art. what do you need help with

Q*bert

Q*bert is an arcade game developed and published by Gottlieb in 1982. It is a 2D action game with puzzle elements that uses isometric graphics to create a pseudo-3D effect. The objective is to change the color of every cube in a pyramid by making the on-screen character hop on top of the cube while avoiding obstacles and enemies. Players use a joystick to control the character. The game was conceived by Warren Davis and Jeff Lee. Lee designed the title character and original concept, which was then further developed and implemented by Davis. Q*bert was developed under the project name Cubes. Q...

Destructible Lemon

it's going to have like, endless mechanics or something though?

the viewpoint is centred on the player character

anyway, i intentionally drew the blocks freehand. if i wanted perfect geometry, i would figure out how to use pil or use the straight line tools or something. or use gimp

I could put more roguelike elements in it even...

Zacharý

And *graphics

ASCII-only

@DestructibleLemon ... you could use MS Paint to draw straight lines

Destructible Lemon

> use the straight line tools

Οurous

I think in your instance it would be better to have it running with shitty textures / models / sprites, and then see if you can do / get help with better ones.

Destructible Lemon

3:18 AM

i mention gimp, because there's still a small amount of skill in making the lines meet up exactly in simplistic editors

@Οurous I could make more exact graphics really quickly, i'm choosing not to

it gives it character

recursive

so like... what actually happens in the game? You just move up... either left or right? What's the goal? What's the challenge?

Destructible Lemon

uh, attacking enemies i guess? distance?

it's pretty vague at the moment

I think there might be boss enemies or something

I think you might need some more specific ideas before you ask anyone for help.

does that answer have a decent explanation?

MD XF

I'll read (all of) it when I'm satisfied with the bytecount of my primality tester

Destructible Lemon

does doing v into : not work?

MD XF

@DestructibleLemon yeah I think so, the only thing I'm confused about is why you thought Quarterstaff was a BF-derivative; was it simply because you used [] for loops?

(I recall you mentioning it in talk.tryitonline.net awhile ago)

Destructible Lemon

i don't know... sort of because when i made it, i copy pasted a lot of the code i used for the bf interpreter i made

and it is partially because of the control flow

which was decided on because it matched bf for the challenge

I made a fizz buzz a little while ago. it abuses the fact that while it goes to 100, you never have to print a 3 digit number

it stores the digits as two numbers

also i guess that the non-variable accessing commands only operate on the one value

like bfs + and -, i guess

should the bf implementation in this challenge have limited size cells or infinite cells? I think i could even make two challenges, since really they're distinct enough

because you've got the challenge of storing arbitrary sized values with limited cells, but not with unlimited cells

ASCII-only

3:51 AM

@DestructibleLemon why not with unlimited cells

Destructible Lemon

with unlimited cells, you can just make the cell that value

with limited cells, you have to devise a special system for storing these values, and arbitrarily increasing them, without disrupting other values

you can't just store them in one place

ASCII-only

ah

I thought you meant infinite tape

Destructible Lemon

like, with unlimited, you could convert variable names to numbers through some sort of base, then use that cell

i think it's not insanely difficult with limited cells, though

you have a few options: you could store it as stacks on the tape, which means that you shift values over as you try to find a value, then you can make it as long as you like, since it's at the top of the stack

stacks on the tape being even and odd numbered cells, each stack getting one of each parity, or something

either way, probably shouldn't discuss in here since i have a dedicated room

The interpreters have been made, so the challenge will be made...
