The Nineteenth Byte

Using regex in interpreted languages for lexing is common

Having the C-based regex engine do the loops is faster than writing a state machine in Python

ASCII-only

Wow I finally updated Sublime and JS highlighting looks so different now

quartata

Perl lends itself to particularly beautiful lexers due to how scalar position tracking works

Of course I'm biased

betseg

@ASCII-only good different or bad different?

ASCII-only

@betseg Good, this is the one in May where they added highlighting of arguments

Helka Homba

@betseg What is codegolf.stackexchange.com/questions/92660/… saying that rohan didn't say?

@quartata Example?

Q: Stop Replacing my tabs with four spaces

Typing Literal Tab Characters I do not know how feasible this is, for the developers, but I do believe, that at least on this site, it may make more sense to stop expanding tabs into four spaces. If the browser side code can be made to render tabs as four spaces, this issue is moot. Some code go...

quartata

sub tokens {
  my $target = shift;

  return sub {
    TOKEN: {
      return ['INTEGER', $1]    if $target =~ /\G (\d+)        /gcx;
      return ['PRINT']          if $target =~ /\G print \b     /gcx;
      ...
      redo TOKEN                if $target =~ /\G \s+          /gcx;
      return ['UNKNOWN', $1]    if $target =~ /\G (.)          /gcx;
      return;
    }
  };
}

stupid chat markdown formatting

There we go

So this returns an iterator essentially

\G is an anchor that anchors to the last position of the previous regex match

Helka Homba

@Downgoat I made the task trivial because programming with the code constraint will be very difficult

quartata

The c flag means that if a match fails the position stays at where it was

And x juts allows whitespace for readability

@Downgoat don't defend your vote -.- I'm just stating my opinion as well

Helka Homba

@Downgoat Though I do appreciate a downvote-with-comment :3

Downgoat

@HelkaHomba reason I don't think it should be trivial task I.e kolonorov complexity is I expect some HQ9 like language will probably win it rather than some language syntax abuse language

quartata

@NewMetaPosts triggered

@Downgoat That's why it's Hello Earth instead

Helka Homba

yeah

quartata

I don't know any esolang with a built-in for that

Helka Homba

00:12

I knew Stuck would win if it was "Hello, World!"

Dennis

@JonathanAllan It doesn't concatenate. It prints the result before 0, then sets the return value to 0. You can only use it as a full program, which I mentioned it in my answer.

ASCII-only

@quartata Oh nice

Jonathan Allan

@Dennis ah I see.

Dennis

In any case, ;0 would have saved a byte. Jelly let's you mix characters and numbers.

Jonathan Allan

yeah I recall ...now

I thought ¡ was repeat?

and ? was ternary if

missing from wiki's quicks page or reuse of same byte in different flow?

Conor O'Brien

00:25

@HelkaHomba :/ your challenge is impossible in BF

Helka Homba

@ConorO'Brien try esolangs.org/wiki/Lenguage

Conor O'Brien

yeah

feersum

You could probably do it in a self-modifying dialect.

Conor O'Brien

that is true

feersum

Like [[<<..]]

And then you have undoubled program.

DJMcMayhem

00:27

@NewMainPosts Ooooh, I wonder if that's even possible in brain-flak.

It would be really hard because you'd be restricted to "Push twice", "Evaluate the sum of the stack (destructively)", and "Evaluate the height of the stack * negative one"

Helka Homba

@RohanJhunjhunwala If it helps (or hurts?), there are lots of well-received source-layout's that I expect wouldn't work in many tc languages because of syntax limitations. But that's somewhat the point with source-layout, or at least a liability

ASCII-only

@ConorO'Brien I wonder if it's possible in JSFuck (I don't think so because no +)

Conor O'Brien

@ASCII-only I tried that already :(

no ++

@HelkaHomba hooray for lenguage :P

Downgoat

@HelkaHomba I think unary will do well in your challenge :D

shit ninja

DJMcMayhem

@Downgoat Shush, I was just working on that

Downgoat

Or a list of unimplemented ones

Downgoat

@ASCII-only yes

Conor O'Brien

@ASCII-only maybe marbelous?

Downgoat

@ASCII-only I'm supposed to tell you the spec? Wheres the fun in that!

Conor O'Brien

@Downgoat uh my answer broke your userscript

no leaderboard >_>

ASCII-only

00:40

@ConorO'Brien but that already has an implementation

Conor O'Brien

oh

I thought you meant for the challenge

ASCII-only

Oh

Downgoat

@ConorO'Brien ;_; y u do dis

wait what leaderboard

Conor O'Brien

in the userscript

ASCII-only

Deflectors/increment/decrement/bitshift/return only though, seems possible but too lazy

yes

Downgoat

then how are you seeing leaderboard

ASCII-only

00:42

@Downgoat no why ;_;

Conor O'Brien

@Downgoat is that by design? I was complaining that it wasn't there

Downgoat

oh :| yeah, leaderboard only shows when theres > 1 answer

ah

ASCII-only

pls anyone i need something to do ;_;

Downgoat

@ASCII-only suggestion: halp maek ches

right now I'm working on cheddarfiles which are part of the module system.

problem is I don't hvae any idea on how cheddarfile will look

ASCII-only

@Downgoat Can you try opening a floobits workspace

Sp3000

@HelkaHomba Can I dupe hammer to this?

Downgoat

Project Name: Description

^ idea

@ASCII-only floobits?

is floobits in anyway related to Geobits?

oh

afaik floobits needs neovim and i dont got neovim ;_;

C9 workspace?

feersum

00:48

@Sp3000 Wow, exact duplicate.

Helka Homba

@Sp3000 I guess so :(

Sp3000

I was starting on a ><> answer then I went "hang on, haven't I done this before?"

Helka Homba

At least it shows it's not a bad idea

Conor O'Brien

@HelkaHomba can I haz accept ? :3

feersum

There's a Self-Modifying Brainfuck answer with [[..<<]] which I had upvoted.

ASCII-only

00:50

@Downgoat That's fine as well

Helka Homba

@ConorO'Brien No. I might change it so it's not a dupe

Conor O'Brien

oh ok

I saw that accept flash on my answer too ;_;

ah well

Downgoat

I gave a presentation on Formal Grammar and Automata theory in class today and this was everyone's reaction:

Conor O'Brien

@HelkaHomba you might just want to ask a new question :P

Downgoat

@ASCII-only ok one sec

Sp3000

00:52

@HelkaHomba While I'm at it, it's a bit awkward hence I want to ask first - can I take command line input but assume empty STDIN input for ><><<<<><><><><><

Downgoat

maybe i should create cheddarfile in C++ for practice :D

but idk cmake

that seems important

i also idk how big C++ projects are layed out

upandright

is my profile messed up

or is this just me

quartata

Uh no it is messed up

upandright

damnit

my bro is messing with my SE account

he's got my school tablet somewhere and messing with my settings

quartata

Your chat profile is set to vi se

change it back to ppcg

Conor O'Brien

01:25

I think I did

it looks fine locally

quartata

also is your brother a mod? because you would need a chat refresh

Conor O'Brien

no, he's messing with my settings locally

Dennis

Your dragon looks as envisioned by a junkie, but it seems fine otherwise.

Conor O'Brien

\o/

I should probably change that back now

quartata

how are you doing this without a refresh

Conor O'Brien

01:27

Conor the Magic Dragon

I think parent account changes occur naturally?

or maybe I'm a mod at beer.se :P

quartata

01:47

@ConorO'Brien FWIW I checked in on Beer SE recently and they seem to be doing better. I think the scope refocus helped a lot

PhiNotPi

enter PhiNotPi

Conor O'Brien

HI!

Nathan Merrill

greets Phi

quartata

Beer is rather narrow; all alcohol is a better scope for a site

Conor O'Brien

notices that Phi/SE changed his avatar

Geobits

01:48

Wait, Helka posted two duplicates in a week or so? Bring back Calvin!

Conor O'Brien

@quartata ah, true

PhiNotPi

Wow it's been a while since I've been here.

Also... oops I missed my chance to become a room owner.

Geobits

So long it changed your avatar.

PhiNotPi

clears cache wtf

quartata

Thinking of good KoTH ideas is hard

Geobits

01:49

Very hard :(

Conor O'Brien

@quartata KotH: beer

Nathan Merrill

@quartata I have a couple of old ones you could borrow

quartata

I was thinking of a bridge KoTH where two instances of the bot make up the partnership

But it would be very very hard

Geobits

That would be cool if I knew bridge at all.

Nathan Merrill

oh, bridge, as in the card game

I was thinking physical bridges

quartata

01:51

I was thinking duplicate bridge specifically

PhiNotPi

okay, is my avatar fixed now?

Nathan Merrill

...still blue. I like the blue though

Geobits

Still blue for me.

The pattern is nice, but it could be a touch darker. It's hard to see on white.

quartata

The problem is it would be too hard (+ not enough bridge players here). There would be little competition

Geobits

Maybe something simpler, like euchre or hearts, first?

Nathan Merrill

01:53

Rook is a good partnership game

PhiNotPi

how about here? codegolf.stackexchange.com/users/2867/phinotpi?tab=profile

Geobits

Hmm, I haven't played rook.

quartata

I'm trying to think of some other good card games yeah

Geobits

@PhiNotPi It's "right" there. Just needs a chat refresh or time I guess.

Dennis

@PhiNotPi Gravatar did something weird. Many identicons have changed.

Nathan Merrill

01:54

also, while its conceptually cool to have different code bases to "partners", it makes life a lot easier if its the same codebase

and you can place restrictions to prevent data passing

PhiNotPi

wow, 3 weeks of inactivity, that's a new record

quartata

I thought two instances of the same bot would be easier

There's no way to prevent covert channels anyways though

Nathan Merrill

@quartata in the post, you simply disallow it

quartata

Oh what a miraculous thing

Conor O'Brien

@quartata Z80 is an assembly language that becomes a machine language, right?

quartata

01:57

Assembly is just syntatic sugar for the underlying machine code

Conor O'Brien

ah

quartata

Things like ADD and INC all have underlying binary representations (called opcodes)

Conor O'Brien

ah. so the opcodes are the machine language?

Geobits

Has anyone here used smileBASIC? I'm thinking of getting it for Minibits, but a review would be nice. Looks nice to me though.

quartata

Yeah.

Conor O'Brien

01:58

@Geobits be careful, it has while...wend loops

Nathan Merrill

@Geobits that's really cool

Geobits

@ConorO'Brien Everyone should have while...wend loops :P
