Hi all

anyone up?

Redwolf Programs

I am :p

@Lyxal Just invent a language that only has two operators and usually has really long answers but can sometimes be short because the control flow is compact and the operators are weirdly overloaded and then use it a few times and forget about it every few months then sometimes realize someone else is better at it than you and try to make more answers in it and sometimes update the interpreter then realize it isn't turing complete so change a major aspect of the language so it is but

3

then decide you prefered it when it was probably a finite state automaton because it stuck way closer to your original vision and there was so much more room for creativity within the limited possibilities so just add an option to the interpreter to use the old version but never actually do because you have more important things to do than spend hours working on an answer in a language you made a long time ago and need a lot of practice in

3

or is that just me

Razetime

@fomin I am

fomin

:) what time zone?

Razetime

need help with reopening the question?

oh it''s already open

fomin

Thanks!

Just needs answers now

Lyxal

@RedwolfPrograms no, I think what you missed is the part where you make an entire language based upon a concept you vaguely remember from a dream that you woke up from at 7am, spend about an hour making it only to have it turn out to be just another BF clone that uses curly brackets and desmos math logic, and have control structures that you aren't even sure work.

Then name it with a cringey name, put effort into making an esolangs page, forget about it for several months finally asking Dennis to place it on TIO.

And then laugh when you see your CG friend use it in an answer and ping you in the comments.

but that's prolly just me

(note that I actually asked Desmos why the expression {} evaluates as 1 and they said it was because it allows for people to type empty brackets without breaking their equation)

@fomin you'll find that non-CG challenges are a whole lot less popular here.

ASCII-only

for the "i don't like curry" question, wonder if rust macros are allowed

i feel like that'll probs be the only way to do it at all

or generics i guess? but still not sure if that counts as a function

Anush

09:48

Morning all

@Adám that's a bit sad. Are they more popular somewhere else?

Adám

10:01

@Anush I don't think so. In fact, I don't know of any programming sites where that's the main focus. I think that most people just find shortening code inherently more exciting and enjoyable than speeding it up.

Rahul Verma

I guess this ruby code isn't valid for I don't like curry

... but I can't find any valid reason

Actually in ruby, curried proc supports both syntax: f[1][2][3] and f[1,2,3]

@RahulVerma It's worth asking in comment

not to mention it may be a bit complicated

Razetime

alright then

When I add a bounty to my challange, is it ok to say I will award it to the fastest solution for a language and choose which one on the basis of how impressed I am by it?

Razetime

absolutely

it's your choice who you award your rep to

fomin

@Razetime I don't have time to write a lovely list of reasons yet but I will do if no one else does

@Razetime cool

ASCII-only

@fomin i'm fine with it (and i'd imagine basically everyone would) as long as you do what you say in the bounty text

fomin

@ASCII-only cool. Thanks

@Razetime any other suggestions?

does jelly even have functions

Kinda

Each line is a "function" I guess

ASCII-only

ok, does it have curried functions

caird coinheringaahing

For sure not in the conventional manner, but I'm sure there's some work around there :P

I tried going down the "generate code then eval" route

Help Stack Exchange transpose tables Stack Exchange doesn't know how to transpose tables. Let's help. Given a markdown table, transpose it. Input assumptions: All cells have equal either no leading space or exactly one leading space (you must handle both) If the cells have a leading space, then ...

Adám

15:09

@cairdcoinheringaahing Hm, but technically it isn't ASCII art at all, but rather generating markdown code/generating a table.

caird coinheringaahing

16:57

Any feedback?

Adám

@cairdcoinheringaahing Assuming you've triple-checked your test cases, it looks good. Two changes I'd make: I'd use i instead of k (for obvious reasons), and (also) provide test cases in a format that is easier to copy and paste.

caird coinheringaahing

@Adám Updated to have both a full table as well as some easy-to-copy test cases

@ASCII-only I was thinking of adding a bit more support for dict objects in Charcoal

fomin

the bounty is up!

ngn

18:06

@fomin yes, as i'm generally interested in fastest-code challenges, but i solved a very similar one recently, so i need some time to forget

fomin

18:26

@ngn oh what was it?

ngn

oh, there's a bounty!

@fomin what was what? :)

fomin

"but i solved a very similar one recently" <--

ngn

@fomin as you can see ^^ i've forgotten already :)

fomin

:)

hooray!

what language do you like to use for fastest-code?

ngn

@fomin c, of course

@fomin i also like vector languages like k or apl, but they don't cope well with scalar operations and non-uniform data

ngn

19:04

@fomin now that i read it more carefully, this challenge seems a little too trivial. you just have to find the right buffer size.

ReedsShorts

19:20

Sometimes I wish that i could just get pure numbers from input instead of having to convert them when using FALSE.

because instead of doing something simple, I have to use 1_0[^$1_=~][0\[$32=~][48-\10*+^]#%]#% to get a list of integers from stdin

caird coinheringaahing

@ReedsShorts Have you had a look through the accepted I/O methods? There might be something that's nicer/shorter allowed (e.g. functions, ARGV etc.)

ReedsShorts

19:38

well that saves a bunch of bytes off my code

fomin

@ngn I don't think that's right. How are you going to do the iteration efficiently? Too much duplication will kill you for example

ngn

@fomin iteration is nothing compared to i/o

ReedsShorts

i will try to the the closest strings in FALSE

however the problem is that the output might exceed 128k

fomin

@ngn I will pipe it to dev/null for speed testing

ReedsShorts

also should i assume that string data is already pushed to stack or should i read it from stdin?

ngn

19:53

@fomin how much ram do you have? :D

fomin

@ngn 16gb. The output size is less than 20mb! :)

ngn

@fomin oh, so it can be a single write(), nice

fomin

Yes

Neil

... so many secret hats...

fomin

I am intrigued how fast your code is going to be!

ngn

19:57

@fomin without algorithmic optimisations: ~200ms but this laptop is old and slow

fomin

That's pretty cool. For what length input string?

ngn

@fomin obenquillo - that's 10

fomin

Got you. Try it with a length 16 string with all letters different

That should be the slowest

ReedsShorts

@fomin should i assume string is already on stack or should it be input from stdin?

caird coinheringaahing

@Neil Those are the fun ones :P

fomin

19:59

Inputted from stdin makes my life easier

ReedsShorts

will do

ngn

@fomin 560ms

fomin

Nice... But surely can be made faster :)

ReedsShorts

just got all three string operations implemented

and already 128ms, great

based on tio

ngn

@ReedsShorts ah, good idea :) i forgot tio exists

Adám

20:05

Try or don't try, there is no time.

ngn

@ReedsShorts how do you redirect to /dev/null on tio?

ReedsShorts

the problem with tio is that output might be > 128k

i dont think you can redirect to /dev/null

Adám

@ReedsShorts Why not?

ReedsShorts

But how would you do that with other languages?

caird coinheringaahing

You'd run the language from the command line

Try it online!

Adám

20:09

@cairdcoinheringaahing , i.e. run under TIO's bash, redirecting output to /dev/null

Try it online!

ngn

aha! and the .c file can be cat-ed from a heredoc

thanks @cairdcoinheringaahing @Adám

fomin

@ngn I would love to know what your algorithmic approach is?

ngn

@fomin the dumbest possible :)

CMQ: What's the best way to word "Here are some inputs that aren't known if their corresponding outputs exist. You don't have to worry about them for now, but if the outputs are shown to exist, your program should work for those inputs"?

ReedsShorts

aight i kind of understand

fomin

20:17

Your code is impossible to read. The dumbest approach is to iterate over all strings and check the edit distance so it can't be that

@ngn ^^^

ReedsShorts

i would have to figure out how to run FALSE code redirecting to /dev/null though

ngn

@fomin no, that would have been impossibly dumb :)

it applies all possible edits in two levels of recursive calls

ReedsShorts

my approach currently is to iterate over methods and positions

fomin

@ngn do you make all strings at distance 1 and then make all strings at distance 1 from those?

ngn

@fomin i make all edits in place, and fill a big buffer with them, and at the end write() it

fomin

20:19

@ngn :)

ReedsShorts

this is gonna be hard and my goal is to just make a working program for now

fomin

@ngn how do you iterate over all the different ways of doing 2 edits?

Adám

@ReedsShorts Try it online!

caird coinheringaahing

@ReedsShorts This should work. Put your FALSE code between the DOCs (or the .s for Adam's)

ngn

@fomin recursion

fomin

20:21

Sounds not so dumb :)

ReedsShorts

yep works

fomin

How much duplication do you have?

ngn

@fomin possibly a lot.. i think it depends on the structure of the input

fomin

Yes it will. Try all a's

ngn

@fomin i believe you without trying :)

but dupes are ok, right?

ReedsShorts

20:23

@fomin my approach is to basically have 3 nested while loops

fomin

@ngn yes. They might just slow you down

I look forward to your answer. Please do make it read from stdin

ngn

@fomin i'll make an offering to the gods of randomness so they won't give you such input :)

@fomin but that costs an entire syscall! :)

ok, i'll make it read from stdin..

ReedsShorts

omg im gonna have 4 nested while loops why

nice

my code so far is 1000000x times worse

and probably 4x slower

ReedsShorts

20:52

so my code so far works fine in the interpreter im using but not in tio

it works fine in the specific language when selected, but not in bash when redirecting to /dev/null

wait nvm figured it out

ReedsShorts

@fomin can i output the strings in reverse or does it have to be in the same order?

21:40

starting over great

fomin

21:58

Any order you like@ReedsShorts

Is your code intelligible ? :)

caird coinheringaahing

@fomin Well, I'm guessing it's written in FALSE, so that depends if you know FALSE :P

Adám

@cairdcoinheringaahing That's so true.

i decided to quit writing it in false bc it sucks

im gonna try python

like no array support whatsoever

also my false code was really unreadable like everything else ive made in false
