[prisma wave]

So return []

[ocean quartz]

Nice I'll take a look in a sec

[oblique heath]

ahh

[prisma wave]

Also why are you taking a Float parameter?

why not an Int?

[oblique heath]

just for fun, i'm going to turn it into just the decimal portion

it may as well be an int here though

[prisma wave]

Probably better as an int

[oblique heath]

those last two lines are still made at me

now i feel like i'm not using sequence correctly

actually..

[prisma wave]

Yeah sequence operates on lists

Or Traversables if we're being specific

[oblique heath]

is there a replacement for sequence for single values

oh wait i guess not huh

wait... how do I call sequence on the list only one time

[prisma wave]

hmm

it might be easier to not do the recursion yourself in this case

[oblique heath]

;o

[prisma wave]

You could instead use something like replicateM

[oblique heath]

ah i saw that in the coc

is there really no way to use recursion for this though 😦

what If i skip the sequence in here and actually return [IO Float]

and call sequence on that afterwards

or are there other issues with doing it recursively besides that

[prisma wave]

No you could do sequence later

That's fine

Or just do it in the inputs function

inputs n = sequence $ case n of 
    | Blah

[oblique heath]

o.O

[oblique heath]

wait can i do that with this function

[static zealot]

why white theme? 😢

[oblique heath]

input :: Int -> [IO Int]
input amount = sequence $....???

like that?

[onyx loom]

i tried to get toolbox to install ultimate correctly so i uninstalled it

it annoys me the way it says "manually installed" programs in toolbox

its disgusting

and toolbox wasnt installing any IDEs at all so

[prisma wave]

import Control.Monad

inputs :: Int -> IO [Float]
inputs n
   | n < 0 = return []
   | otherwise = replicateM n (readLn >>= (return . read))
   
main = inputs 2 >>= print

The repl.it editor is horiffic on mobile but this is what I came up with

I think it works

[prisma wave]

Should be returning IO [blah]

[oblique heath]

ahh

[lime ember]

Is it possible to let HTML code run in a markdownfile (Github - README.md)?

https://github.com/Jak0busus/Jak0busus/blob/main/DINOGAME.md

[jovial warren]

no

that's parsed as Markdown, and the parser (in this case, GitHub's internal parser) only understands Markdown

[ocean quartz]

MD should only accept simple HTML, no Js

[jovial warren]

^

[prisma wave]

declarative only 🙂

[oblique heath]

huh, i got

FirstHaskell-exe.EXE: user error (Prelude.readIO: no parse)
Received ExitFailure 1 when running

[prisma wave]

🥴

well that's new

Were you using readLn or readLine?

[oblique heath]

input_line <- getLine
  let num = read input_line :: Int
  inputs num >>= print

[prisma wave]

Idk what the difference is

[oblique heath]

is my main

[prisma wave]

what's inputs?

[oblique heath]

the function you gave

[prisma wave]

try using getLine instead of readLn

Forgot that existed lol

[oblique heath]

oki

that worked lol

[prisma wave]

Oh actually readLn might be better

But cool

[oblique heath]

what's the difference o.o

[prisma wave]

readLn is like getLine + read

It does the parsing for yoyn

[jovial warren]

https://i.imgur.com/6YpAHN4.png lol?

[oblique heath]

oooo

[onyx loom]

@half harness what https://github.com/dkim19375/dkim19375Core/blob/master/src/main/java/me/dkim19375/dkim19375core/function/HexaConsumer.java

[oblique heath]

that sounds like exactly what i'd want to use for the recursive version

[half harness]

lmaoo

[ocean quartz]

Does spark create detailed report like aikar's timings?

[prisma wave]

Indeed

[jovial warren]

what the fuck is that package name

[prisma wave]

So it could just be replicateM n readLn or do it recursively if you'd prefer

[half harness]

IDK

[onyx loom]

that whole package is just cursed

[half harness]

🤣

[jovial warren]

ik your name has numbers in it, but numbers in packages 🤮

[onyx loom]

like why

[half harness]

i didn't know what to name it

[prisma wave]

Shoulda used Haskell

[jovial warren]

also, HexaConsumer lol

[ocean quartz]

When in the world would you ever need a hexa consumer?

[jovial warren]

(T, U, V, W, X) -> Unit ez

[oblique heath]

wait how would I use readLn normally

like if i just wanted to get an input in main

[half harness]

probably never

[eternal compass]

How can I get an account on the Ecloud site? I am creating an expansion

[ocean quartz]

Then why?

[oblique heath]

i'm trying stuff like let num <- readLn input_line but with no luck

[half harness]

🤷

[prisma wave]

input <- readLn :: Int

[oblique heath]

o

that simple huh

[onyx loom]

matt, look at the other classes in the package

[prisma wave]

should be

[half harness]

lol

[ocean quartz]

Dkim, you make me question my sanity

[onyx loom]

it makes no sense

[prisma wave]

Reads a line from stdin + parses

Ez

[oblique heath]

wait what's input

[prisma wave]

just the name

It can be anything

[oblique heath]

input <- readLn :: Int

this actually didnt work, it wants to be an IO Int

[steel heart]

bruh allman is so unreadable

[onyx loom]

?

how so

[steel heart]

it just is

[prisma wave]

oh yeah it does need to be IO Int

even though input will be of type Int 🥲

[oblique heath]

weird

[prisma wave]

makes sense when you think about it

[onyx loom]

i need evidence caught in 4k pls

[prisma wave]

the <- operator effectively pulls the value out of the monad

[steel heart]

ma'am sure

[oblique heath]

oh true

[prisma wave]

(even though that's not what's actually happening)

[oblique heath]

i forgot that existed there

[steel heart]

E V I D E N C E -> ||allman sucks||

[sinful parcel]

Hey guys is it possible I can have a server record in game gameplay as a match replay?

(I wanna see the world burn)

[oblique heath]

so for the function i could do

inputs :: Int -> IO [Float]
inputs n
   | n < 0 = return []
   | otherwise = replicateM n (readLn)

for the replicate version

[onyx loom]

thats crazy

[half harness]

woah

[half harness]

is it just me or does that look bold

[steel heart]

its objective evidence

[half harness]

bold

[onyx loom]

damn ur right

[half harness]

😮

[prisma wave]

Cute

[onyx loom]

gonna have to start using haskell style in kotlin now

[prisma wave]

You don't even need the parens 🙂

[oblique heath]

😮

[onyx loom]

semi colons in kotlin 🙂

[half harness]

hi

[oblique heath]

now for the recursive version

input :: Int -> [IO String]
input amount
  | amount < 0 = return []
  | otherwise = (readLn) : input (amount-1)

this almost works

but the empty list is giving issues again

[eternal compass]

hello

[oblique heath]

do i just give a normal list this time, without the return?

ah indeed i do

[prisma wave]

yeah you would

Again you don't need parens around readLn I don't think

That's pretty hot tho

[oblique heath]

xd

now i'm stuck with an Int -> [IO Float] function though

[prisma wave]

that's where sequence comes in

[oblique heath]

gotcha

wait how do i fit that in here

this

input amount $ serialize $ case n of 
  | amount < 0 = []
  | otherwise = (readLn :: IO Float) : input (amount-1)

is not happy

[prisma wave]

input amount =

not $

[oblique heath]

ah right xd

[prisma wave]

You shouldn't need the type hint either

[oblique heath]

still mad though, at the guards now

[prisma wave]

Yeah they're not quite as nice

[oblique heath]

the IO Float hint?

[prisma wave]

yeah

[oblique heath]

oh yeah look at that

fancy

[prisma wave]

the haskell type inference algorithm is insane, I don't think you need the hint

sick

[oblique heath]

but yeah the guards are mad now

[prisma wave]

oh

ohh

You use -> for a case syntax

Not =

[oblique heath]

oo

[prisma wave]

I did the opposite earlier and got confused lol

[oblique heath]

input amount -> serialize $ case n of gives me an error on the ->

😦

so this is where i stand now

input :: Int -> [IO Float]
input amount -> serialize $ case n of 
  | amount < 0 = []
  | otherwise = readLn : input (amount-1)

wait

[prisma wave]

No no

[oblique heath]

i need to return IO [ Float]

[prisma wave]

= for the function

[oblique heath]

o

[prisma wave]

and then like amount < 0 -> []

[prisma wave]

And yes you do

[oblique heath]

so like

input :: Int -> IO [Float]
input amount = serialize $ case n of 
  | amount < 0 -> []
  | otherwise -> readLn : input (amount-1)

this is still mad

[prisma wave]

case n?

with amount

actually I'm confused now

[oblique heath]

i dont even know what the case n of is really doing here

is it making a list?

[prisma wave]

I think you just want case of

It's pattern matching

[oblique heath]

oh yep

[prisma wave]

Just like you did with the guards before

Just a different syntax

[oblique heath]

that fixed it

[oblique heath]

what do you mean o.o

oh

what is it replacing?

[oblique heath]

nvm it did not fix it :/

it's now giving a parse error on case of

[prisma wave]

Its replacing the previous syntax with the guards

Pretty much does the same thing

[oblique heath]

wait so i should remove my guards now?

[prisma wave]

uh

Can you send what you have ATM

[oblique heath]

ye

[prisma wave]

You're confusing me here lol

[oblique heath]

input :: Int -> IO [Float]
input amount = serialize $ case of 
  | amount < 0 -> []
  | otherwise -> readLn : input (amount-1)

what exactly do the -> in my cases do by the way

are they making an IO for serialize to use

or something else

[lunar cypress]

they are just part of the case expression

I think

the same as in java or kotlin

[oblique heath]

how come they changed from =

[lunar cypress]

oh is it = usually

[prisma wave]

because = is for the function definition

whereas -> is part of the case expression

[lunar cypress]

ah yeah

[oblique heath]

we were using = for the case expressions before though weren't we

[oblique heath]

like here

[prisma wave]

that's a guard

not a case

[oblique heath]

ahhh

[prisma wave]

similar thing, slightly different

[oblique heath]

gotcha

so case of uses ->

[prisma wave]

yeah

[oblique heath]

and both case of's and guards use pipes

i see

[prisma wave]

correct

i think in cases you need _ instead of otherwise

[oblique heath]

i changed it but the same error as before is showing up, the parser error on case of

input :: Int -> IO [Float]
input amount = serialize $ case of 
  | amount < 0 -> []
  | _ -> readLn : input (amount-1)

[prisma wave]

oh

hmm

case might need a value

maybe case () of

or just use if/else

idk

not familiar enough with the nuances of haskell

[oblique heath]

;-;

case () of brings back the parser error on the first pipe

[lunar cypress]

yeah honestly this seems like an if else situation

[prisma wave]

yeah if else is probably the best thing here

[oblique heath]

what if i had like 4 cases here

would i be forced to use an if else arrow

[prisma wave]

probably not

you could probably match it based on something

it's situational

[oblique heath]

well i can probably just leave the function as Int -> [IO Float] for now

and maybe just make a second function that combines it with sequence?

not that that's ideal either

[prisma wave]

no pls dont

that's even more ew

[oblique heath]

i just did

(sequence $ input num)

in main

with input returning [IO Float]

xd

[prisma wave]

🤢

[oblique heath]

i'd still like to figure out how to return IO[Float] without using ifelse though 🥲

[heady birch]

fn main() {
}

[lunar cypress]

(repeatedly n read) 🙂

[old wyvern]

Alrighty

[prisma wave]

@oblique heath spent some time trying to figure it out and i can conclude that it's probably not possible or very inconvenient at least to do in your way

input :: Int -> IO [Float]
input amount
    | amount < 0 = return []
    | otherwise = readLn >>= (\x -> (input $ amount - 1) >>= (\y -> return (x : y)))
``` this is the closest i got and it doesn't even work lol

replicateM is probably the best option

[ocean quartz]

Was thinking about adding support to same command but different implementation:

@SubCommand("foo")
fun first(player: Player, string: String)

@SubCommand("foo")
fun second(player: Player, int: Int)

But sounds so complicated to implement correct 😩
Specially for tab completion

[obtuse gale]

ah yes, because we all want suggestion completions for numbers

[oblique heath]

darn, well thank you for humoring the idea

[obtuse gale]

oh boy I can't wait to see

1
2
3
4
5
6
7

[static zealot]

that was an example fefo... smh

also I did that once

lmao

:)))

[obtuse gale]

LMAO

[static zealot]

they have String[] let them use that :)))

[ocean quartz]

I might, sounds too complicated for something that'll hardly ever be used

It's cool but

[static zealot]

true

[jovial warren]

hey does anyone here want a fun challenge?

I kinda want a lag simulator plugin for Krypton, so I can see if TPS measuring and watchdog is working properly lol

I mean, delay would probably do what I want tbh

[prisma wave]

while true

delay doesnt block

[jovial warren]

/lag tps lol

[prisma wave]

thats the point

[jovial warren]

it does if it's ran from a runBlocking coroutine https://tenor.com/view/smart-thinking-thoughts-think-ponder-gif-7713620

apparently, delaying for 100ms brings the TPS down to ~10 lol

oh spark is so amazingly good lol

2021-03-25 20:36:07 [main] WARN KryptonServer - Woah there! Can't keep up! Running 30441022900ms (608820458 ticks) behind!

I can only laugh at that

[oblique heath]

how

[jovial warren]

I'm purposely making ticks take an extra 100ms to monitor the effects

I wanted to see if spark would be able to monitor TPS properly on Krypton

[oblique heath]

right but this 608820458

this is a lot of ticks

[jovial warren]

yeah ik

[oblique heath]

that's about 8455 hours

just under a year

[jovial warren]

wanna see code?

[oblique heath]

sure

[jovial warren]

while (isRunning) {
    val nextTickTime = System.nanoTime() - lastTickTime
    if (nextTickTime > 2000L && lastTickTime - lastOverloadWarning >= 15000L) {
        KryptonServer.LOGGER.warn("Woah there! Can't keep up! Running ${nextTickTime}ms (${nextTickTime / 50} ticks) behind!")
        lastTickTime += nextTickTime
        lastOverloadWarning = lastTickTime
    }
    lastTickTime += 50L
    eventBus.call(TickStartEvent(tickCount))
    val tickTime = measureTimeMillis(::tick)
    eventBus.call(TickEndEvent(tickCount, tickTime, System.nanoTime()))

    if (tickTime < TICK_INTERVAL) delay(TICK_INTERVAL - tickTime)
}

[oblique heath]

System.nanoTime()

wouldn't that give nanoseconds?

[jovial warren]

okay maybe I'm stupid

yes, it would

[oblique heath]

ye xd

[jovial warren]

yeah idk why I thought using nano time was a good idea

I guess precision

I literally only just switched that to nano time lol

that's why I only just got that warning

[stuck harbor]

use unix clocc

u nerd

just one number

[jovial warren]

oh yeah, because unix clock is available on Windows

https://tenor.com/view/smart-thinking-thoughts-think-ponder-gif-7713620

[stuck harbor]

unix clocc is one number that represents the amount of milliseconds since the start of 1980

[jovial warren]

OMFG

[stuck harbor]

just one number needed to show the exact time

[prisma wave]

1970*

[stuck harbor]

shut

thats what i said

[prisma wave]

🙂

[oblique heath]

isn't that already what currentTimeMilis returns?

[jovial warren]

1. 1980
2. you know that's what nanoTime and currentTimeMillis give you right?

[stuck harbor]

hehe

uh

k

then keep using that

gg

[jovial warren]

please tell me you knew System.currentTimeMillis() returns a unix timestamp

[oblique heath]

no uses windows time

[stuck harbor]

uhhhh

uhhhh

uhhh

[half harness]

whats a unix timestamp

[stuck harbor]

i defo don't just use LocalDateTime objects

nope

not at all

[jovial warren]

omfg I was literally just about to say even dkim isn't that stupid

[oblique heath]

xd

[jovial warren]

and then I find out he actually is

[jovial warren]

oml

[oblique heath]

anyways back to nano vs miliseconds

[stuck harbor]

i use localdatetime objects everywhere

wheee

[jovial warren]

not even gonna bother to explain this, just gonna link you to Wikipedia

[oblique heath]

no real reason to use nanoseconds

[half harness]

wait

[jovial warren]

gj wasting memory

[half harness]

system.currenttimemillis uses

[jovial warren]

https://en.wikipedia.org/wiki/Unix_time

[half harness]

unix timestamp?!

[jovial warren]

omfg dkim

[half harness]

i thought it had to do something with system

https://tenor.com/9p1d.gif

[half harness]

like from system startup

or something

yk

[oblique heath]

whenever you see a single long number that represents a time

[dawn hinge]

Lol

[oblique heath]

that's the unix timestamp

[half harness]

because like System.currentTimeMillis

System

🤷

[jovial warren]

currentTimeMillis

[half harness]

yes

oh

🤦

[jovial warren]

omfg

[half harness]

u said that like 3 times

the past minute

[jovial warren]

because I'm just sitting here laughing

[stuck harbor]

shitting here laughing**

[jovial warren]

currentTimeMillis
system startup

one of these things is not like the other

[half harness]

is listening for packets without protocollib a good idea

so that i dont have dependency

[stuck harbor]

no

[oblique heath]

are you concerned about your jar size to that extent

[half harness]

wot

protocollib = plugin

[stuck harbor]

dkim u have more things to be concerned aboot

what

[half harness]

aboot

[stuck harbor]

what

[half harness]

what?

@oblique heath NEVERMIND

GOT IT

import Data.List

readFloat :: IO Float
readFloat = readLn

input :: Int -> IO [Float]
input amount
    | amount <= 0 = return []
    | otherwise = readFloat >>= (\head -> (\tail -> head : tail) <$> input (amount - 1))
   
main = input 2 >>= print

beautiful

import Data.List

readFloat :: IO Float
readFloat = readLn

input :: Int -> IO [Float]
input amount
    | amount <= 0 = return []
    | otherwise = readFloat >>= (\head -> (cons head) <$> input (amount - 1))
    where cons a l = a : l
   
main = input 2 >>= print
``` even better 🤤

thats actually the hottest thing ive ever written

[lunar cypress]

spending hours on implementing a function that reads 3 floats

just haskell things

[prisma wave]

🥲

but muh purity!!

[lunar cypress]

(cons head) <$> input (amount - 1) wtf is this abomination

[prisma wave]

best thing ive ever written

input(amount - 1).let { cons(head, it) }

[lunar cypress]

I mean I get what it does but why'd you do this so weirdly

[prisma wave]

weirdly?

like the whole thing?

or just that

[lunar cypress]

just that

[prisma wave]

oh wait

lmao

yeah

[lunar cypress]

why use $ there
and why define cons at all

I'm just confused

[prisma wave]

oh no there is a reason

i can't just do head : input (amount - 1)

because input returns IO [Float]

<$> is to cons to the [Float]

why define cons at all
lambdas are gross

[lunar cypress]

guess I just don't get <$> then

[prisma wave]

it's just an infix for fmap

which just maps across a Functor

this is gonna sound pretentious but its so cool to finally know what that means

[lunar cypress]

left is the function, right is the functor?

[prisma wave]

yup

there's apparently <&> which is the other way around but i couldnt get that working

[lunar cypress]

foo >>= (return . bar)
bar <$> foo
would those be equivalent then?

[prisma wave]

i believe so

[lunar cypress]

I wonder where those symbols come from

[prisma wave]

idk

>>= kinda makes sense

<$> is just random symbols as far as im concerned

[lunar cypress]

yeah I mean >>= at least makes aesthetic sense

[old wyvern]

Whats <$>?

[prisma wave]

infix fmap

[old wyvern]

tf xD

[prisma wave]

fmap f a == f <$> a

[old wyvern]

Wait so its equivalent to bind?

[prisma wave]

kinda

[old wyvern]

Whats the diff?

[prisma wave]

fmap works on functors

[stuck harbor]

pure functions must be

1. unintelligible by OOP dweebs
2. taking hours to design

[prisma wave]

bind is only for monads

[old wyvern]

ah

[prisma wave]

btw is pure just the same as return?

looks like it is

[old wyvern]

Well kinda

There was a difference

You can check the Hasklash thing

I had to use it there for the Rest calls

[prisma wave]

https://img.bristermitten.me/chrome_EhVwLtHHO1.png

[old wyvern]

Also the demon that is "liftIO"

[lunar cypress]

The way it looks to me is that fmap is more like map as opposed to flatMap if we use java/kotlin as comparison

[old wyvern]

ah

[prisma wave]

seems like it is, but pure is for functors

[prisma wave]

yeah that sounds about right

[old wyvern]

functors as in functions?

[lunar cypress]

no

[half harness]

@prisma wave best game ever

[prisma wave]

ikr

i keep disabling it

and it still comes up

[half harness]

lol

[old wyvern]

a functor is a mapping between categories

[prisma wave]

welp gone now

[prisma wave]

A type f is a Functor if it provides a function fmap which, given any types a and b, lets you apply any function of type (a -> b) to turn an f a into an f b, preserving the structure of f.

[old wyvern]

Is that not what a function is?

[lunar cypress]

yeah that's the category theory thing

no

functions map between sets

[old wyvern]

They explains functors* as functions in one category theory course on yt

welp]

The one linked you bm

[prisma wave]

i think functions might be functors actually

o

[lunar cypress]

Well I guess technically they are functions

but they have a few more things going on

not every function is a functor

[lime ember]

^^what would you do now?
I waited 5 days now, and he didnt answer...

[old wyvern]

ah

[prisma wave]

oh yeah lol

instance Functor ((->) r) where
    fmap = (.)

[lunar cypress]

you remember linear transformations/homomorphisms between vector spaces from LA yugi?

I think functors are similar but for categories

at least that's what my prof said when he mentioned it once

[old wyvern]

Yes

ah

this was that playlist btw

https://www.youtube.com/watch?v=NcT7CGPICzo&list=PLbgaMIhjbmEnaH_LTkxLI7FMa2HsnawM_&index=5

[prisma wave]

😟

[lunar cypress]

ah yeah, they're just the equivalent of group, ring, field, vector space, you-name-it-homomorphisms

[old wyvern]

hmm

[stuck harbor]

functional programming is good

makes it more like maths

incredibly difficult to understand

caps

[oblique heath]

heck yeah xd

[prisma wave]

actually beautiful

[oblique heath]

what does the <$> represent there

[prisma wave]

that is an infix version of fmap

which is basically like Optional#map but for any functor / monad

[oblique heath]

huh

[lunar cypress]

I feel like using fmap directly would make this cleaner

[prisma wave]

possibly

(\head -> fmap (cons head) $ input (amount - 1)) is this nicer?

maybe

[lunar cypress]

fmap (head :) $ (input (amount - 1)) shouldn't this work, in theory?

[prisma wave]

oh can you curry the cons operator?

let's see

[lunar cypress]

I think so?

[old wyvern]

yes

[prisma wave]

yup you can

:)

[old wyvern]

Haskell OP

🥲

[prisma wave]

(\head -> fmap (head :slight_smile: $ input (amount - 1))

lmao

whoops

[lunar cypress]

Gotta love discord inline code

[prisma wave]

(\head -> fmap (head :) $ input (amount - 1))

[old wyvern]

xD

[lunar cypress]

but see that's why I was wondering about your custom cons earlier

[old wyvern]

Reminds me of.... lis--

[prisma wave]

ah yeah i didnt realize that

wait can you curry any infix operator?

[lunar cypress]

yeah you should be able to

[oblique heath]

hmm when i try to run what you made, BM, i get

    * Couldn't match expected type `[IO Float]'
                  with actual type `IO [Float]'

[prisma wave]

huh

[oblique heath]

wait

nvm

[prisma wave]

import Data.List

readFloat :: IO Float
readFloat = readLn


input :: Int -> IO [Float]
input amount
    | amount <= 0 = return []
    | otherwise = readFloat >>= (\head -> fmap (head :) $ input (amount - 1))

[oblique heath]

my main is

num <- readLn :: IO Int
  input num >>= print

[prisma wave]

ah

[heady birch]

so i built a todo list in spring + hibernate, just to access it through elinks browser...

[prisma wave]

yeah lol

(readLn :: IO Int) >>= (print . input)

[oblique heath]

o.o

[prisma wave]

wait

[oblique heath]

i put that in my main but i'm still getting the error

[prisma wave]

huh

[prisma wave]

you using exactly this?

[oblique heath]

function

readFloat :: IO Float
readFloat = readLn

input :: Int -> IO [Float]
input amount
    | amount <= 0 = return []
    | otherwise = readFloat >>= (\head -> fmap (head :) $ input (amount - 1))

main

hSetBuffering stdout NoBuffering

  putStrLn "Enter a number: "
  --input_line <- getLine
  (readLn :: IO Int) >>= (print . input)

[prisma wave]

what line does the error?

[oblique heath]

....

it's a different function

[prisma wave]

lolwut

lmao

[oblique heath]

🥲

oop now i have an error on

(readLn :: IO Int) >>= (print . input)

[prisma wave]

whoops

input . print

[oblique heath]

Couldn't match type `IO ()' with `Int'

;-;

[lunar cypress]

print . input should be right

[prisma wave]

yeah i thought it is

input . print works though

strangely

[static zealot]

this chat is such a mess 😦

[prisma wave]

where

[oblique heath]

that main line again

[static zealot]

that's because I can't read it :)(

[onyx loom]

does someone not like haskell? 👁️

[static zealot]

I can't like something that I don't know and understand

well maybe I can

[prisma wave]

send latest code

[oblique heath]

main = do
  hSetBuffering stdout NoBuffering

  putStrLn "Enter a number: "
  (readLn :: IO Int) >>= (print . input)

  --putStrLn $ "list: " ++ (show $ input num)
  return ()
  
readFloat :: IO Float
readFloat = readLn
  
input :: Int -> IO [Float]
input amount
  | amount <= 0 = return []
  | otherwise = readFloat >>= (\head -> fmap (head :) $ input (amount - 1))

[static zealot]

but yeah you can say I don't like it

[onyx loom]

neither do i tbh 👀

[static zealot]

ah ok

[prisma wave]

ivan can u send imports

[oblique heath]

sure

[prisma wave]

i wanna test

ty

[oblique heath]

wait

do i need to import list..?

import System.IO
import Data.List

import Control.Monad

i only have these

wait im blind

i am importing it

[prisma wave]

lol

i dont think u need data.list anyway

or control.monad for that matter

[oblique heath]

huh

well here's my code exactly as i have it

module Main where

import System.IO
import Data.List
import Control.Monad

main :: IO ()
main = do
  hSetBuffering stdout NoBuffering

  putStrLn "Enter a number: "
  (readLn :: IO Int) >>= (print . input)

  --putStrLn $ "list: " ++ (show $ input num)
  return ()
  
readFloat :: IO Float
readFloat = readLn
  
input :: Int -> IO [Float]
input amount
  | amount <= 0 = return []
  | otherwise = readFloat >>= (\head -> fmap (head :) $ input (amount - 1))

[prisma wave]

(readLn :: IO Int) >>= input >>= print

this worked

pretty sure it didn't like the composition operator combined with the IO

[lunar cypress]

the composition probably doesn't work because print returns IO

[prisma wave]

yeah

[oblique heath]

ayy it works for me too xd

[prisma wave]

or because input returns IO and print just expects a Show

pretty sure thats the reason

[lunar cypress]

yeah, that way around

[oblique heath]

what does this part mean (head :)

[prisma wave]

🙂

[oblique heath]

🙂

happy code

[prisma wave]

it's just a curried version of the : operator

with some unfortunate parentheses

[oblique heath]

ah

[prisma wave]

\x -> head : x

[oblique heath]

that makes sense

at least the operator part

i cant understand why it has to be in those parenteses

[prisma wave]

cuz otherwise it would try and do head : $

[oblique heath]

😮

would it be valid to take it outside the parentheses, but also swap the $ for it's own set of parentheses

[prisma wave]

nope

[old wyvern]

You dont need the $ if you already have a parenthesis on the left expression I think

[prisma wave]

because then it's head : (blah)

[oblique heath]

what is it right now

[prisma wave]

not sure exactly why but it breaks without $

[oblique heath]

is what we have now (fmap head) : (blah)

[old wyvern]

Which expression?

[prisma wave]

fmap (head :) $ input (amount - 1)

[lunar cypress]

you do because it's still left associative

[prisma wave]

yeah

[old wyvern]

ah the left expression isnt fully wrapped

[prisma wave]

it's gonna be fmap (head :) input (amount - 1)

[lunar cypress]

it would become ((head 🙂 input) (amount - 1)

[old wyvern]

mhm

[prisma wave]

lmao

that god damn operator

[oblique heath]

🙂

[old wyvern]

head :slight_smile: indeed

[prisma wave]

Man haskell is cool

[oblique heath]

well at least now i can rest easy knowing it's possible to get a list input in one line

[prisma wave]

For a language so focused on purity it's very flexible

[prisma wave]

Only took 2 days!

[oblique heath]

yep 🥲

[old wyvern]

replicateM?

[prisma wave]

Yeah I suggested that the other day

[old wyvern]

ah

[oblique heath]

sorry, one line recursive*

[prisma wave]

Just doing it recursively for learning experience

[old wyvern]

It can be done in done line

[oblique heath]

with no where block*

[old wyvern]

ah

[old wyvern]

huh?

[oblique heath]

not block but

no where

[old wyvern]

Why would you need a where?

[oblique heath]

this thing

[static zealot]

man you know what's funny? I can almost read this

[old wyvern]

replicateM already returns a list tho

Or did you mean the same without that?

[oblique heath]

but it's not recursive 🤩🤩

[old wyvern]

🥲

[oblique heath]

so it's cheating

in my book

[static zealot]

recursivity can suck a dick

[oblique heath]

how dare you

don't make me invert a binary tree on you

[old wyvern]

Burn in hell

[lunar cypress]

"recursivity"

[static zealot]

"ITS JUST A PRANK BRO!! JUST A PRANK!!

[old wyvern]

https://tenor.com/view/hail-satan-fire-elmo-burning-gif-13464669

[prisma wave]

You're dead to me

[prisma wave]

The implementation probably is

[static zealot]

wasn't I already?

[oblique heath]

for replicateM?

[prisma wave]

Almost

[prisma wave]

Yeah

[unkempt tangle]

Senpai

[oblique heath]

well maybe it is but then it'll just go back and inline it, if i understand right

so it goes full circle

[prisma wave]

I had a look at the source earlier and it's kinda complicated but it's probably recursive

[static zealot]

Time to mass PING

clojure good

[lunar cypress]

there's more where that came from

[old wyvern]

xD

[static zealot]

oh hell. I've been appending the ascii code

to the string

and didn't know why the hell I was getting a long number

lmaoo

[forest pecan]

you can just cast it into a char

lol

[static zealot]

yeah well I didn't lmao

[forest pecan]

xD

[static zealot]

I didn't realise

I didn't

[static zealot]

share code

also all this could have been just 1 line smh

oh

spoilers don't work on multiple lines

nvm then ain't showing it

[forest pecan]

i just did (char) (Integer.parseInt(str, 16) for each line

lol

[static zealot]

I was like: "I won't spoil it" and here you come lmao

[forest pecan]

oy

oh

[static zealot]

yeah I made a new variable for the integer (ascii value) and then I did appeneded the int.toChar()

[forest pecan]

o

yo my teacher is afk for 20 minutes

poggers

i can code my task chain

😄

[static zealot]

or you can play some more coc

@half harness @stuck harbor are you both afk?

[forest pecan]

nah i want to get my command chain finished 😭

[half harness]

i cant figure it out

:c

[static zealot]

I mean pulse

gave you the whole thing

[oblique heath]

i give up

[half harness]

oh

[oblique heath]

i am nowhere near big brain enough for hex -> asccii with haskell

[stuck harbor]

wdym am I afk

[forest pecan]

yea integer.parseint is nice with radix

lol

[half harness]

oh that was hex?

[static zealot]

didn't read his full name lmao. thought its you

[forest pecan]

Yeah

[stuck harbor]

haha

[half harness]

oops

[oblique heath]

xd

[half harness]

i thought it was ascii code -> text

[forest pecan]

yes there are letters in numbers

lol

[half harness]

thats why i was so confused

[prisma wave]

Actually not that difficult

[half harness]

oof

[prisma wave]

Pretty sure there's something in standard library for it

[oblique heath]

i couldn't find anything in ~5 mins of googling

the closest thing was a stackoverflow function

that didnt work for me 😂

[prisma wave]

Hex -> Base 10 -> Char

[oblique heath]

😮

[oblique heath]

shh

[oblique heath]

forget i ever used python

[half harness]

wot

[stuck harbor]

py... thon?

[oblique heath]

dont mind that

[stuck harbor]

I use python apps all the time, actually

[static zealot]

new game if anyone else wants to join

[forest pecan]

when you code on your other computer but realize that you haven't ran buildtools on it

[half harness]

oooooooooooooooooooooooooooooooooooooooooooof

[static zealot]

don't do that. just use paper

smh

[half harness]

just copy and paste the folder in .m2

[stuck harbor]

1.13?

tf

[half harness]

you still have to run buildtools

[static zealot]

also yeah

1.13?

[forest pecan]

yea lol

[static zealot]

you have to run the paper jar

[half harness]

and buildtools

[static zealot]

well there's a command

[forest pecan]

look at all the versions

[static zealot]

you have to use

[forest pecan]

look at the errors

[static zealot]

not true dkim

[forest pecan]

not just 1.13

look at the errors

lol

[static zealot]

I did it like last week

[stuck harbor]

1.8?

oh no

[forest pecan]

it's everything

lmfao

[half harness]

paper jar doesn't have mc code in it though

[stuck harbor]

including 1.8

[forest pecan]

yep

[stuck harbor]

ffs

remove your system immediately

[static zealot]

it does tho. afaik. I used NMS by running just the jar

last call ^

starting it

[half harness]

but thats against the license whateveritscalled

distributing mc server jar

[forest pecan]

paper installs it for you

i think

[static zealot]

well I might be wrong but I remember I only had to run the jar

yeah it installs it from the internet

or whatever

[half harness]

but the jar itself doesn't have the code

[half harness]

wot

[forest pecan]

yea

it just builds it for you

[static zealot]

but you just need to run one command

[half harness]

run?

[forest pecan]

you didn't know?

lol
