Wat

HyperNeutrino

I have like 10 functions that take a function as input and return a function

it's almost like I made ~~tacit~~ Python \o/ [I don't understand what tacit means]

Anonymous

@HyperNeutrino I don't think you understand what tacit means

wizzwizz4

@HyperNeutrino lambda stack, *arguments:. It's called in more than one place.

HyperNeutrino

probably not

Anonymous

Tacit aka pointfree means code that doesn't refer to its arguments/parameters explicitly

HyperNeutrino

15:01

Oh okay

wizzwizz4

@totallyhuman Are you saying that HyperNeutrino has self-issues? :-O

HyperNeutrino

The way I have it, you can keep calling functions on the functions but at the very end of the chain it explicitly calls the function with the arguments because it can't do it any other way xD

HyperNeutrino

@wizzwizz4 I won't deny it :D

Example: f n = n `rem` 2 == 0 is a pointful function in Haskell for testing parity. f = (0 ==) . (rem 2) is the equivalent pointfree definition.

@HyperNeutrino That's called a fluent interface

Somewhat, but with big changes to fix the issues

HyperNeutrino

Oh okay. That makes a bit more sense, thanks.

Learn How To Be Transparent

Hey, I am stuck at this JavaScript challenge:

Write a function called 'sum' that should be usable as follows:

sum(1, 2, 3) // should return 6
sum(1)(2)(3) // should return 6
sum(1, 2)(3) // should 6

Note, the function can have any number of arguments, not just 3.

Anonymous

15:03

@LearnHowToBeTransparent Look up currying

Step Hen

@LearnHowToBeTransparent check if each arg is a function, if it is call it

wizzwizz4

@LearnHowToBeTransparent That's terrible.

What if you want sum(1, 2, 3)(4)?

Nathan Merrill

@StepHen none of the arguments are functions

Leaky Nun

How can sum(1,2,3) be not a function but sum(1) is a function?

Learn How To Be Transparent

Well, here is my attempt: https://repl.it/JsLN
But I have to call the function like so:
sum(3,4,5)()
sum(3,4)(5)()
sum(3)(4)(5)()

wizzwizz4

15:05

@LeakyNun It's a flawed problem.

Leaky Nun

@LearnHowToBeTransparent is it guaranteed to have only 3 inputs?

wizzwizz4

@LearnHowToBeTransparent That's fine. It's not possible otherwise.

Learn How To Be Transparent

the problem is, no

wizzwizz4

Unless you're converting to int.

Step Hen

> Note, the function can have any number of arguments, not just 3.

Leaky Nun

15:05

@LearnHowToBeTransparent you can't do it.

Nathan Merrill

can you make a custom number type?

Business Cat

Yeah, as written it's not possible. Because a(1, 2) should give 3, but a(1, 2)(3) should give 6, which means 3(3) = 6 which doesn't make sense

Nathan Merrill

aka, it acts like an integer, but is callable?

Step Hen

@LearnHowToBeTransparent gimme a sec I think you can do it

HyperNeutrino

@Okx Oh thanks

I'm just about ready to give up on 05AB1E

What's with everything turning into strings for no good reason? If I wanted strings I'd use strings

5

I typically prefer my numbers to be numbers not sure if it's just me...

Okx

does it affect any behaviour?

HyperNeutrino

It makes sorting not work I think

For the 2048 challenge that came out last night, this should work

Okx

15:30

well i mean you can use one of the bytes to cast to integer if it doesn't work

HyperNeutrino

Well actually that takes 3 extra bytes

Like I got it to work: ε0K}Dε€ï{}síε€ï}Q

But does it really need to be that clunky?

I mean if my numbers didn't have identity crises it would work better

Okx

@HyperNeutrino so what's wrong with that?

HyperNeutrino

Well, strings aren't sorted correctly; the sorted list should be [2, 4, 8, 16] but it's ["16", "2", "4", "8"]

Step Hen

@HyperNeutrino Use cQuents, it doesn't have strings

HyperNeutrino

@StepHen lol

Okx

15:34

@HyperNeutrino I see no strings

HyperNeutrino

My language technically can have strings because I added a 2-byte thing that makes strings from codepoints but you can only add them in at the end

Step Hen

and the "strings" it has I'm contemplating removing

HyperNeutrino

@Okx Well yes that works but not really because if there are 0 cells it doesn't work

Step Hen

although I eventually want to be able to do string sequences too, but that's for later

Okx

@HyperNeutrino wdym

HyperNeutrino

15:36

[16, 8, 0, 4] is truthy but it sorts to [0, 4, 8, 16] for which I need to ignore the 0s

Okx

HyperNeutrino

Bruce Forte

Bruce Forte

15:44

No, I get "Server's response could not be decoded"

@BruceForte That's weird - you might hop on over to the TIO chat room and ask around

Bruce Forte

Oh, now when I click the link I provided I get that same response and only when I click run I get that message :S

@HyperNeutrino you're obviously doing something wrong

HyperNeutrino

@StepHen Well duh xD

I think it's maybe integer overflow?

16:00

@HyperNeutrino my base conversion in Explode works, you want to look at that code?

HyperNeutrino

@StepHen Sure, thanks.

@DJMcMayhem Terrible handwriting is kinda the point. More diverse handwriting samples = better challenge

Step Hen

@HyperNeutrino Probably not optimal, but github.com/stestoltz/Explode/blob/master/explode.py#L343

HyperNeutrino

Oh lol that's the code I'm using

I think it's probably integer overflow

Step Hen

@HyperNeutrino do you have the -1? That threw me off (unless you're doing it slightly differently)

DJMcMayhem

16:02

@Mego What if it's embarrassingly bad? :P

Verging on illegible

HyperNeutrino

No, I am using base-115 to convert the digits [1,1,1,1,...,1] with about 20 1s though

Step Hen

actually I think the -1 is because I'm doing it weird

@HyperNeutrino want to TIO what you're doing?

Step Hen

so wait what's wrong with it

HyperNeutrino

I'm trying to get it to break...

well now it won't break lol

Step Hen

so your Ceres dependencies broke it :P

HyperNeutrino

That's really odd

It's working on my computer now too

Step Hen

16:07

@HyperNeutrino add your dependencies back, manually (no undo) and if it's broken again you know the problem

HyperNeutrino

@StepHen No I didn't even remove the dependencies

Step Hen

@HyperNeutrino oh lol

HyperNeutrino

Besides, the dependencies don't really do anything it's just for the fluent interface

Step Hen

> fluent interface

what's that?

HyperNeutrino

Essentially I call functions on functions and keep chaining them on each other and then at the very end call the whole thing with the arguments

so like vectorize(listify(intify(function)))(arguments)

Step Hen

16:09

I like ASTs better, seems like they are simpler and easier to debug

HyperNeutrino

ಠ_ಠ

So it still sometimes breaks on my computer but the case that breaks it doesn't break on TIO

Maybe it is the dependencies?

Step Hen

@HyperNeutrino just maybe

HyperNeutrino

heh it's floating-point inaccuracies

Step Hen

@HyperNeutrino oh lol

why do you have floats involved?

HyperNeutrino

Doing list(map(float, [...])) breaks it

@StepHen everything is a float

or a complex number

Step Hen

16:10

oh right and you are doing **

HyperNeutrino

yes

Step Hen

@HyperNeutrino if you want to mess around with Explode it's on TIO - I need to add a flag for tape output each tick though, for it to make any sense

HyperNeutrino

oh okay

thanks

Step Hen

it also can't carry stuff over so it can't do real addition yet

HyperNeutrino

I should probably use ints; it wouldn't break any operations

yay I got it to work

Anonymous

16:15

@HyperNeutrino Oh, that's a bit different from a fluent interface. That's function composition.

wait so you have different modes that are run based on what the input is?

@HyperNeutrino the mode is ?

but yes more or less

HyperNeutrino
