doesnt this kinda seem like the sandbox: meta.stackexchange.com/questions/377768/…

or am i just going crazy

i would not at all be surprised if it's inspired by it

a couple of sites have their own sandbox already and i had a discussion about it with the cms at our last meeting

@AidenChow it's a better version, because it'll (should) be actively supported by SE, rather than some hacky workaround that we use

While helpful, it can't actually replace the sandbox without a lot of features that SE's probably not gonna implement :|

Idk, a lot of the features detailed in that post are either equivalent or better than existing Sandbox stuff

The only thing I dislike about it from a Sandbox PoV is

> Questions that are not approved by Reviewers will be auto-published after a defined period of inactivity, except for questions that have received a close vote or flag, or where a Reviewer has asked for major changes that were not made.

i'm not a fan of it being restricted to people who have access to it as reviewers

unless that's something we can custom set

...yeah for this to replace our sandbox it would definitely need some custom tuning

@cairdcoinheringaahing yeah i'm not a fan of that cuz it makes it not really practical for us to use sandbox for very WIP things that might take a long time to actually become usable or are purely ideas for a while

gonna make a bot that autoflags everything in the staging ground to prevent auto-posting

@allxy now that's a good one

@hyper-neutrino I don't hate this, but I do prefer the Sandbox being open to all to review

@pxeger and a kinda useful one :p

"This" being the inactive posting thing

ah

We'd want it to be settable to "100 years" though

perfect

is that doable?

i'd hope "disabled" is a valid setting lol

set it to 5 years, forget it wasn't disabled, and face a dramatic crisis when the time comes

there are a lot of things i wish SE let us set per-site that would make the site a lot better catered to small sites / weird sites like us that wouldn't even really require any new features

@pxeger I suspect so. We have quite a few site specific settings that are "high enough to basically mean never"

lol yeah isn't our autoprotect setting like 10000 answers or smth

@pxeger The year is 2122. Thousands of low-quality questions are flooding the gates of CGCC. We do not know how much longer we can survive...

@hyper-neutrino Yep, Shog absolutely hiked it up because of the Sandbox

and I think Catija increased it on main a while back as well

yep

@pxeger Prefix operators already exist in Python, how hard would the postfix ones be to implement?

Postfix would be slightly harder than prefix, but for just a new statement it would work fine

Just add a __rop__ to all the type classes (where op changes for the postfix op name) :P

if it's only usable as a statement and not an expression does it even matter which side the ++ is on

or is that not what you meant

++a would be ambiguous with +(+a)

which, to be fair, is the same in C

To truly settle the debate, it should be ++a++ and both pre and post increment

@pxeger How does C sort that out?

i assume it just tries to do ++a if it's not illegal to

@allxy C has ++ as a separate token

@cairdcoinheringaahing I just realised that one reading of this means that ++a++ would add 2 to a

and return a+1?

...oh god, that's bad

tio.run/##Sy4o0E1PTv7/PzOvRCE3MTNPQ1OhWqEotaS0KE/BUEFbW8HIWqH2/… nvm it just tries to do ++ and if it fails it just dies

@cairdcoinheringaahing and even better, it returns the value in between, not a or the final a + 2

Oh god, hyper

...does Proton have a separate type for 1???

sympy

ah

apparently does

ah

keep in mind that proton was made several years ago back when i had literally zero knowledge of how to actually make programming languages

It also has a type for Half as well

@allxy Also, One should be callable, and return... well, 1, when called

i kinda want to make a new language sometime now that i've just finished a course that had us literally make a programming language :P

nice

> return postfix_operators[tree.token.content](tree.children[0], symlist)

@allxy yeah thats why flax doesnt use sympy, i dont need a separate type for one lol

Proton settles the debate then, ++ is postfix

i thought i was taking a course like that but it was just implementing a boneless lisp in java

@hyper-neutrino Are you planning on using the language here?

@cairdcoinheringaahing Try it online!

@cairdcoinheringaahing wdym, the language that i plan to make or the one from the course

cuz the one from the course is just an extremely small subset of c++ lol

Yes

@hyper-neutrino Definitely use it then :P

:p

yeah our assignments were like

It's already small, it'll do great here :P

ಠ_ಠ

@hyper-neutrino show the syntax :0

like fizzbuzz

procedures → procedure procedures
procedures → main
procedure → INT ID LPAREN params RPAREN LBRACE dcls statements RETURN expr SEMI RBRACE
main → INT WAIN LPAREN dcl COMMA dcl RPAREN LBRACE dcls statements RETURN expr SEMI RBRACE
params →
params → paramlist
paramlist → dcl
paramlist → dcl COMMA paramlist
type → INT
type → INT STAR
dcls →
dcls → dcls dcl BECOMES NUM SEMI
dcls → dcls dcl BECOMES NULL SEMI
dcl → type ID
statements →
statements → statements statement
statement → lvalue BECOMES expr SEMI

@hyper-neutrino Honestly it's not bad

that's the parser specification

@allxy oh trust me it is :P

BECOMES?

BECOMES is = lol

anyway yeah i won't disclose much more in case policy or whatever but as you can see it's extremely limited

@hyper-neutrino For a second, I thought that was a sample piece of code in the language

lol

^^

@cairdcoinheringaahing Lol, same

Even the most cursed languages don't replace ( and ) with LPAREN and RPAREN :P

well

thanks for the idea

oh no

print lparen quote Hello, World! quote comma end equals quote \n quote rparen

github.com/hyper-neutrino/postfix-lang

IN PARSE COPY 3 SWAP MODULO 110 GOTO SWAP SKIP SWAP SWITCH PROCESS 3 RECIPROCAL MULTIPLY FLOOR 9 GOTO PROCESS "LUCKY\N" SWAP "UNLUCKY\N" SWAP SWITCH POP 0 GOTO PROCESS

JAVA?

yes

add an operator that isn't :: but just the literal text T_PAAMAYIM_NEKUDOTAYIM

java was once my primary language

@UnrelatedString ^^

#redundancy

what does that mean lmao

lol, ADDITIVE_INVERSE :P

wtf

It's PHP, what do you expect?

what language is that

or does it not actually mean anything

hebrew

obligatory phpsadness.com

ah

> F BIT_FLIP: Pops the top of the stack, flips all bits, and pushes the result onto the stack. Only works on numbers. For example, 7 F will return 0 because 7 = 111, 000 = 0. 10 F will return 5 because 10 = 1010, 0101 = 5

hyper, I do not like this

why not :P

so F F is not an identity lol

For starters, you'd expect this to be self-inverse, but 7 F F is 1 :P

Oh god it's on TIO

(I'm guessing it's 1, I don't actually know)

oh is that what that is

hyper, explain

Wrong link

tio.run/##K8gvLsn5/99cwU3BTe//fwA

the TIO version isn't updated

or i never implemented the short form of bit flip

@cairdcoinheringaahing is there something wrong with that

no worry, I'll just add it to ATO

please don't

Please don't

I'm sure it's a really valuable use of my time and disk space

Save your server

@hyper-neutrino F doesn't change the stack size

*eye twitches*

why is it a float?

¯\_(ツ)_/¯

your guess is as good as mine

@cairdcoinheringaahing Just did that lol

@cairdcoinheringaahing isn't the link you sent me just hello world

You made it :P

@hyper-neutrino Ah whoops

I meant the one that allxy sent

ah

anyway if you want even more cursedness just look at the positron source code

it attempts to build the parse tree token-by-token

i think that's LL0?

You meant proton, right?

no i meant positron

Oh great, another one

unsurprisingly, hyper-neutrino likes naming languages after subatomic particles

Lol ikr

i forget how to define functions

@cairdcoinheringaahing Not entirely

Branch is actually a cool language :P

> final commit

lmfao

Lol

@cairdcoinheringaahing And I'm not just saying that cause I helped name it :P

it's also really cursed

It's gonna be worse than last time, isn't it

tio.run/##K8gvziwpys/7/…

@hyper-neutrino IIRC, it's also got an online interpreter with no sandbox, despite being handwritten C

@pxeger i'm pretty sure i killed that

but you are correct

@pxeger If it's on hyper's server, it won't have survived the crashes

I remember spending an afternoon trying to find a memory corruption bug, because I was I sure there would be a way to get ACE

@allxy Proton 2: Subatomic Boogaloo

i don't believe it is capable of causing harm since it has too few features to have ACE and it has manual memory and operation counting and commits suicide after enough resources are used

anyway in case you hadn't lost all faith in me yet, here's some positron code

tio.run/##K8gvziwpys/7/…

is that @ like Mathematica

@hyper-neutrino Bash meets Mathematica :P

yes

except you can't call functions without it

for some reason?

@pxeger Probably not, coming from hyper.

It's probably the soul-corruption operator

I think the soul-corruption operator would be hyper-neutrino himself

I need to finish the spec for Mixology :/

oh fun fact

@ is also the index operator: tio.run/##K8gvziwpys/7/z9RwVYh2lBHwUhHwTiWi6ugKDOvxCHRwfD/fwA

also the same as Mathematica

oh really?

see i am good at making languages

No

And K I think

^^

Mathematica uses list[[index]]

oh

tbh i think i achieved most of the goals i had in mind when making proton

tio.run/##KyjKL8nP@/@/oCgzr0RDQ0NbU0FNwVhTw0RT8/9/AA

@hyper-neutrino I think that level of function application is the direct antithesis to Rutger lol :P

Functions taking more than one argument? Nonsense!

lol

pro tip when making coding languages

if you don't want to write a parser just make people write code in ASTs

and call it a "feature"

@hyper-neutrino even better, if you don't want to write an interpreter, just make people code in the language your language is written in :P

big brain moment

That's a long line of code: codegolf.stackexchange.com/a/206781/66833

Actually, I have no idea why that works. I overwrite the variable containing the loop during the loop ಠ_ಠ

lmao what

Yeah, I have the main loop in the i variable, then immediately overwrite it:

> i=i[{s=Array[Str[$x]];e=Each[$s];e=e[@i]

The e=e[@i] creates a variable i as the iteration variable

Rutger is so cursed

At least proton looks usable on the surface and is for basic stuff

Rutger is usable :P

It just doesn't want to be :P

Lol

CMC: Use Mirror

CMP: What should dyadic pq do?

What does monadic pq do?

palindromise? (because it's a visual palindrome)

wait i mean p and q separatly

or horizontal mirror or something

I'm sat in Geneva airport at the moment, and idk why or how, but my laptop is connected to eduroam wifi O.o

CMP: What should p and q do (both dyadically)?

What do they do monadically? That's the best way to pick a functionality

just give up on q like jelly did

@cairdcoinheringaahing flax is fixed arity

@UnrelatedString Even my fork doesn't have a command for q :P

@UnrelatedString ok lol

what about q for quotient after division?

wait thats just integer division oof

make q the quantum command

given two arguments it creates a superposition of the two

or, more practically, pick one of the two at random

Random choice

how many random choices do i need

i got a monadic one already

Random choice between the two arguments isn't a bad option if you're struggling to fill out dyads

well ok

what about p?

given that quit has no return value, you could just make q a dyadic quit which ignores its arguments

even though it should logically be a nilad

@PyGamer0 That should pick, at random, one of its arguments :P

or just append :P :P

ok then p is pick

and q is dyadic quit whatever that is

dyadic quit is just "quit execution", but where it ignores the arguments provided

ok

    "q": attrdict(arity=2, call=lambda w, x: exit(0)),

wait i have 50 quicks what

and i think i added a fold-fixedpoint and scan-fixedpoint

i can overload a lot on fold and scan ....

oh yeah what does your fold do on monads

I suspect its the same as my fork: <monad>/ is the same as ,<monad>¥/

@cairdcoinheringaahing well i decided to change it

I'm heartbroken :P

@UnrelatedString it does the same thing as k now

i'm almost thinking an option could be to just consume until it hits a dyad, and compose all the monads along the way onto the right

@UnrelatedString So DMMM/ would be DMMMʋ/?

@UnrelatedString +AJKHFAKJHFAJKFHᐣ´ should do the same thing

yep

not sure how useful it would be exactly

That's disgusting, I love it

but it is an idea

@cairdcoinheringaahing er, i actually meant DMMMƊ¥/, but that might be more useful

That does the same thing

er

DMMMƊ}¥/

Oh that's worse :P

much worse

it would pretty much just be a shitty way of mapping the monad[s] over everything but the first element before the fold

versus your interpretation actually inserting something into the fold

DMMMʋ/ basically allows for "run-time" post processing of the fold, DMMMƊ}¥/ just ^^ yeah

@UnrelatedString Tbh, that's not exactly an easy thing to do. I think Ḣ;MMMƊ€ƊD/ is the shortest

to compensate for it being useful, the monads should run in reverse order :P

Random order, randomised between each step of the fold :P

example for flax's fixedpoint scan: =``W8

exact copy of the k version =\\&8

CMQ In python if I want to convert “278.000” to the int 278, do I really have to do int(float(“278.000”)). ?

No

Just int("278.000) should work, no?

^

no actually it doesnt

wait

hmm

thats interesting

@lyxal sadly not

maybe strip the .000?

@PyGamer0 tried that, its the same byte count

wait actually strip returns a string, so it would be longer

int("278.000".strip(".0")) longer than int(float("278.000"))

i dont see a shorter way atm sadly

9
0 1 2 3 4 5 6 7 8
36
1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8

i implemented k's monadic & in C lol

how do i do a markdown table without the header

but it leaves a gray line on top

@AidenChow thanks for trying!

I actually have a list of these strings so I need the ridiculous [*map(int,map(float(L))]

@graffe i think you meant [*map(int,map(float,L))] if im not mistaken

@AidenChow yes, sorry

it's still ridiculous though :)

@allxy I think that's a node from an unloaded document (e.g. frame removed)

Interesting and kinda cursed :P

@allxy am I missing something or does ({\u006cog}=console);\u006c('\x5b\x2e\x6c\x46') work?

@Neil console contains l

That's ... cursed

TIL

({\u006cog}=conso\u006ce);\u006cog('\x5b\x2e\x6c\x46') works though

But wow that's cursed.

Is JS java now or something?

and wtf it literally only works with identifiers

@allxy should I post that as a crack?

If you want, sure

@RadvylfPrograms ... it's actually a minor plot point in OotP?

Yeah, umbridge, although doesn't fantastic beasts (the book) postdate OotP?

@allxy apparently the reference in HP isn't to FB

@Neil with(conso\u006ce)\u006cog('\x5b\56\x6c\x46') for 45

@allxy bah, I've closed the window now

Oh well :P

oh I found in my recent upvotes

Hmm yes

Just been watching gameplay of Patrick's Parabox and holy frick my brain is hurt right now because recursion and cloning

also, I like how VS Code just decided to add coloured brackets in the latest insiders build

wdym?

rainbow parenthesis?

oh taht

@lyxal are there only 3 colors?

yes

ok

i am forking an existing vim plugin for rainbow parenthesis

CMQ: Online interpreter for HQ9+?

Why can I not write echo*:/2 3 in J?

@BgilMidol what are you trying to do

and what is the error?

2 to the power of 3

ok

@BgilMidol *: called dyadically is NAND

you should probably get the reference card

whats nand

Not AND

oh

how do i reduce by pow?

CMQ given a bipartite graph I can find a maximum cardinality matching using Hopcroft-Karp. But how can I find two different maximum cardinality matchings?

@Neil Oh, yeah, I think I remember that now. It's been like 8 years since I read the books

Today's wordle word seems very odd

I'm two guesses in and the letters I have have me stumped

lol

Wait no it's just a very typical english word lol

Questions have been really slow recently

Yeah, they have. I've been trying to think of one for a while now, I think CGCC just has a collective lack of ideas lol

Plus some of our main question askers have been busy doing other stuff recently

@RadvylfPrograms i think i have an idea

but idk if its a duplicate

hey hey, we have a new question!

finally

bruh

Just came back from Fantastic Beasts 3

It was awesome!
