@user part of it is youtu.be/gRdfX7ut8gw, but 1. I feel like this is [Big] enough (or will be) to warrant its own repo and 2. like you said it depends on several rather chunky libraries, like rich

user

01:08

I'm not sure what that video has to do with this but okay, if rich is that chonky then I guess Crosshatch might have to be an optional dependency

Ginger

read the title :p

user

Fiddler on the roof?

Ginger

not quite

user

Tradition?

What's the tradition here?

Ginger

I usually put stuff like that into its own repo

user

01:13

Oh

Seggan

03:12

@user as in like x.set(v)?

user

03:42

No, iirc there was some operator overloading

I don't actually remember what exactly made it hard, I'll have to try out a build.gradle.kts again

Lyxal approved on PR #1562 (Vyxal/Vyxal): "Thank you. I appreciate all the detail here, and how thorough the explanations of the add functions are. "

lyxal

#.😎

That's gonna be the pop 69 push "420" trigraph

And in the debug section it'll print "but why..." if you use it

Vyxal Bot

Lyxal merged PR #1562 (Vyxal/Vyxal) (Vyxal:v3-more-docs → Vyxal:version-3): Write some more docs for v3

Lyxal deleted branch Vyxal/v3-more-docs

lyxal

Some(69), // Takes 69 arguments

Just the idea of something popping 69 items when there's really no chance you'll ever even have 69 items is just really funny to me for some reason

Like imagine the kind of function signature it'd need if you were implementing it as a normal function lol

mathcat

@lyxal This is what v2 is missing.

15 hours ago, by mathcat

Given a list and an integer (not received via input), what's the easiest way to calculate the difference between the integer an each element of the list?

v isn't working either

lyxal

isn't it just -?

□⌈⌊ƒ-

mathcat

wait I prob made a dumb mistake

:face-palm:

I didn't convert it to an int.

adj. good: The (intangibly wondrous) state of having a repl.

@lyxal now I get to bill myself as "the person who made vyxal good (for some value of good)"

lyxal

but not the first :p

Ginger

shhhhhhhhh

aight so

let's get this repl working

lyxal

one problem

I won't be able to help you

Ginger

eh it's fine :b

lyxal

if you say so :p

!!/'night

Vyxal Bot

13:26

@lyxal o/

Ginger

I have elected to drop the "syntax highlight as you type" feature, because it's going to be a galactic pain in the ass to implement

lyxal

@VyxalBot (because it's 12:26am) o/

Ginger

instead I will just have syntax highlighting be applied to a line once you hit enter

...probably, idk if I can make that work either :p

mathcat

@Ginger eh that's probable better

Ginger

13:41

@mathcat @Seggan would yall mind providing me with some regexes for the syntax highlighter to highlight?

idk what vyxal syntax looks like q:

mathcat

well you could use vylight

Ginger

nope

vylight is JS

(and it doesn't use regex anyway)

mathcat

okay I'll do some

Ginger

cool thanks

Ginger

13:58

@mathcat ping

mathcat

sry I haven't started yet lol

I'll start in ~15min

Ginger

ah

mathcat

14:49

so actually

It's going to be a lot harder with pure regex.

You could use "`([^`]*?)`" for string

but I have no idea how to do implicit completion in regex

one sec

mathcat

15:19

I think this "`(.*?(?<!\))`" supports escaping with backlash

I'm pretty sure the same syntax applies the compressed string « and compressed number »

The backslash escaped the next char \\.

Digraphs: ∆ø↔Þ¨k

just colour the next char

Ginger

hi, I am back

mathcat

hey

Lambdas: λ ƛ ⟑ µ ⁽ ‡ ≬ ¨3 ¨2 ' ¨₂ ¨₃

Ginger

you don't really have to use regex, gimme a sec to check the documentation

frick brb :p

mathcat

@mathcat I believe this works tho, it just can't auto-complete strings

some more constants: ₀ ₁ ₄ ₆ ₇ ₈ ¶ ¤ ð × u

@mathcat gosh VyxalS is outdated

ooh variables are interesting

Ginger

15:36

if you don't want to use regex, you can just make a rich highlighter class (which is what I'd be doing anyway with your regex): rich.readthedocs.io/en/latest/…

mathcat

nah I'm the #1 regex fan now

Variable regex: ([→|←][a-zA-Z_]+)

user

@mathcat Yeah ignore the fact that that repo exists lol

Someone should archive it

mathcat

ig new lambdas were added afterwards

Comments: (#.*$)

user

I'm not sure you can use regex to highlight Vyxal effectively

mathcat

watch me

user

15:43

I guess it'll work in like 95% of cases

Just not the 5% where you have strings containing Vyxal characters or something like that

mathcat

Vyxal characters?

user

Like structure openers and stuff

Unless you're using one of those OP flavors of regex, which I assume you're not because you're using Python

Ginger

ok, got variable and comment regex copied over

mathcat

@user ah right

I'm not that good at regex, does somebody know if you can actually implicitly complete strings with regex?

user

You could make the end of the string optional maybe

mathcat

15:48

wdym?

user

?

Ginger

@mathcat so should I use this?

mathcat

@user regex101.com/r/0aYyo7/1?

@Ginger you could, but you'd have to manually check if you need another backtick

Ginger

???

mathcat

e.g this

Ginger

15:55

ok, it looks like if needed extra Python code can be added for things that regex can't do

@mathcat so backticks are auto-closed if the program ends?

mathcat

wait a minute

I'm pretty sure this works: ``(.*?(?<!\))`|`.*`

Ginger

ok cool

mathcat

I hate markdown

Ginger

@mathcat so all of these just get a special highlight?

mathcat

yup

The matches btw, not the groups

Ginger

16:01

???

@mathcat so like [λƛ⟑µ⁽‡≬']|(¨3)|(¨2)|(¨₂)|(¨₃)?

mathcat

yeah

Ginger

alright, I've got comments, variables, strings, lambdas, and constants

user

@mathcat Yeah, does that work?

mathcat

noice

Ginger

tf is a "digraph"

or for that matter a "MOD_CHAR"

user

16:09

A digraph is an element with a two-character name

Ginger

lemme just copy those on over

ok gimme some vyxal to test

mathcat

@user nah, but I think the regex I posted below that works

user

poggers

Ginger

!!/info

Vyxal Bot

mathcat

16:13

lol

@Ginger modifiers modify the element after it

Ginger

ffs I need some vyxal

I'll test it with this fizzbuzz code: ₁⟑₍₃₅kF½*∑∴,

oop it crashed

forgor 💀 to close a bracket

how does it look?

tbh there's less highlighting than I thought

mathcat

noice

kF is supposed to be highlighted tho

Ginger

(ignore the <=, that's part of the interpreter)

@mathcat what is it? I don't see any regex that matches it

mathcat

@mathcat ^

Ginger

@mathcat < is a digraph?

mathcat

16:25

wrong arrow lol

Ginger

yeah I didn't have all the digraphs in the regex :p

here's how it looks now:

mathcat

awesome

Ginger

gimme something else to test with

mathcat

vyxal.pythonanywhere.com/…

right i forgot

‛ groups the next to chars as a string

Ginger

hmmmm

mathcat

16:34

@mathcat ^

‛.. regex

Ginger

16:46

@mathcat

(I changed the digraph color to red because bright yellow is too close to normal yellow in my terminal)

mathcat

eh kinda works

but strings have a higher priority, so the chars after ‛ have to be yellow

Ginger

aight

@mathcat better?

(I can change any of the colors if you want)

mathcat

great!

Ginger

wait lemme rejigger a few things

mathcat

Also, what does this output? vylight.surge.sh

Ginger

16:51

@mathcat ^

mathcat

pog

Ginger

it's, uh, not quite right

pretty sure that @adefinedfunction ain't supposed to look like that

mathcat

yeah, backslash, compression, lists and functions

but I have to leave now, brb

Ginger

adiós

Ginger

17:48

@mathcat ping

Ginger

18:39

@mathcat YOOOOOOOOO IT WORKED

QUICK GIMME SOME VYXAL TO TEST

@lyxal is there an (ASCII) character that Vyxal programs can never start with? I need something to use as a command prefix

@user got any Vyxal to test with?

user

Afraid not

Ginger

sad

but the version on the GitHub dev branch should be functional!

user

@Ginger vyxal.pythonanywhere.com/#WyIiLCIiLCJseXhhbCIsIiIsIiJd

Ginger

~~hey wait a minute~~

well now I have to add that :p

@user github.com/Vyxal/Crosshatch/commit/…

we do a little trolling

user

18:58

lol

How about rickrolling people in the terminal instead?

I think someone suggested that before

Ginger

y'know, that might actually work

I feel like there's a tool for that...

found it

Ginger

19:18

@user we do EVEN MORE trolling

user

Nonono

Do not curl | bash random scripts off the internet

Ginger

aight, I'll figure out how to embed it into the interpreter :p

user

See github.com/jart/hiptext

Ginger

I'm going back to the webbrowser method, we can do this later because I do not have the energy for it

user

Yeah good idea lol

Would've been a little too much

mathcat

19:58

@Ginger what worked

Ginger

the REPL!

mathcat

noice

Ginger

now I'm beating my head against the regex for lists

mathcat

@Ginger how does this render now?

Ginger

one sec

3 hours ago, by Ginger

it's, uh, not quite right

user

20:03

Looks pretty good to me

Other than the |

Ginger

I'm like 90% sure that the lambda at the bottom is wrong, the list is definitely wrong, and the thing with the square brackets has no highlighting bc I didn't know what it was

oh and the weird chevron things

if you want to test the interpreter the version on the dev branch is ok to use (I think)

help would be appreciated on the highlighter

mathcat

@Ginger awesome!

Vyxal Bot

GingerIndustries opened issue #6 in Vyxal/Crosshatch: The highlighter cannot properly highlight lists

mathcat

have you figured the list regex out yet?

Ginger

@mathcat I'm really annoyed that Vyxal Bot sent that message before you, otherwise I could've been like "does this answer your question"

mathcat

20:07

lol

Vyxal Bot

GingerIndustries opened issue #7 in Vyxal/Crosshatch: Write some help for the REPL

it seems to have some... issues with multiline programs tho:

mathcat

20:42

lmao

@mathcat I just realised I said VyxalS I meant Vylight lol

@Ginger chat.stackexchange.com/transcript/message/62828965#62828965

@Ginger it's the "123" and "ergi" here

also, v and = are modifiers, maybe colour the next element

Sry I can't make any good commits my RPI's low on space

@mathcat wait a minute that's not a Vylight feature

Ginger

alright, for multiline programs I think I can just use Shift+Enter for moving to the next line

Vyxal Bot

20:59

mathcat4 forked Vyxal/Crosshatch into mathcat4/Crosshatch

mathcat

@mathcat I'll do these and list regex real quik

mathcat

21:14

I have no idea why this isn't working.

user

What are you trying to match?

Try [^|] instead of .

mathcat

kinda works, but just for the first pipe

which makes sense

Ginger

same problem I've been having

mathcat

I'll give it a try tomorrow, o/

user

Well first off your regex needs to look more like [^|]*(\|[^|]*)*

Otherwise you might as well have \[[^\]]*\]

lyxal

22:20

@Ginger no

This is a golfing language

That'd be a horrible idea if that existed

Seggan

@Ginger ;

its not forbidden, but its useless at the start

or ], or )

lyxal

Or | for that matter

Not forbidden, but acts as a nop

For now

user

22:33

Or # since comments aren’t super useful in repls

Is there a way to take input character by character from stdin for this challange?

7

Q: Implement a 2fuck interpreter

2fuck is a simple 2d variation on brainfuck. Like brainfuck, there is a tape that extends 30000 bytes to the right, consisting of values between 0 and 255. Arithmetic should wrap around, adding 1 to 255 sets the cell to 0, and moving right from cell 29999 should move the pointer back to 0. The co...

lyxal

@AndrovT once you read the program from stdin, do you need to take any other inputs that isn't the simulated stdin?

AndrovT

I need to somehow input the program and then the program itself needs to read input

lyxal

but once you read the program, the only remaining input is the simulated stdin?

AndrovT

I guess

lyxal

¨S

that overwrites stdin to be whatever value is on the top of the stack

so if you give it a string, all calls to input will return the next character

AndrovT

23:20

nice

I'll try that

lyxal

and if for some reason you need to reset stdin after that, ¨R

AndrovT

Time for me to finally use a variable in Vyxal because I need to save the program

user

Try the register instead

Or the ghost variable

lyxal

23:48

@user does scala have input fuzzers?

Or whatever its called when the testing thing creates random data for you

user

Apparently

Google yields results about this Kaizen thing but I can't find an actual repo for it

So maybe it's just a research thing

lyxal

Because I remembered that fuzzing is a thing from the conversation about testing

user

Oh, there's this thing for testing your tests

ScalaCheck (which is integrated into ScalaTest), can do property-based testing with randomly generated values

lyxal

You'll hate me for saying this but how easy is it to integrate that into the project?
