It seemed fine last time you required proof for an open-ended-function challenge, so I'd say yes.

Redwolf Programs

If my whole family wasn't asleep I'd go play it on my sister's electronic piano thing and see if it sounds right

hyper-neutrino

i played it on an online keyboard

and even just reading it, it's certainly wrong

lyxal

first link I found

Wasif

04:36

@RedwolfPrograms what's the time there right now

hyper-neutrino

even if we ignore the number of consecutive keys (megalovania opens with three Ds, the third in a higher octave), it doesn't repeat the C with a higher C

it goes from C back up to the higher D

Redwolf Programs

D D D A G# G F D F G C C D A G# G F D F A B B D A G# G F D F G Bb Bb D A G# G F D F G is the correct opening 4 measures (ignoring length and octave)

Redwolf Programs

Who wrote that site lol...how is that anywhere close to the top of google or DDG results when the author didn't even take the time to write it in musescore or lilypond or something

Or apparently check to see if it was correct

hyper-neutrino

i can understand not knowing enough about music to recognize it, but if you're gonna make a site with notes, you'd better at least know what you're talking about xD

that is so blatantly wrong

also why are there so many As in a row so many times in the middle lol

seems like whoever wrote this doesn't know how to play above that A

Redwolf Programs

Or because they're just writing the names of the notes, they can't write anything higher without it being ambiguous

10/10 notation

hyper-neutrino

the whole higher F F F G G# A C A D D D A D C part is one of my favorite bits of the melody and they just murdered it

Redwolf Programs

04:44

I think we should drop this whole concept of "sheet music" altogether and replace it with this

hyper-neutrino

i mean it's not that hard to write unambiguous notation this way

just put octave numbers after everything

length can be fixed by just appending dashes

that's what i do when i'm drafting stuff on paper and too lazy to deal with trying to make it neat enough to be read as sheet music later

> Note range A3 to D6

bruh, the note range on this is like half an octave

Ok. might take a bit.

If I wasn't feeling a tiny bit delirious, I'd add it to my site

but I don't feel I'd be able to figure out how to rn

Just run interpreter.py

No one here knows how to spell rin right!

lyxal

@Wasif But i'd need to change it first to accommodate being a flask app

STDIN doesn't exactly exist when it's a flask app

A username

@lyxal You'd want to add a dummy account, since as you've complained before, pythonanywhere has multithreading disabled.

lyxal

@Ausername I'd just route it to a different page

Wasif

@lyxal I have already tried, and just was going to finish an interpreter but stuck on the point of porting the interpreter to a function

So porting to pure JS might be the best option

It has an unfinished interpreter in 2ddeadfish.pythonanywhere.com

The design is quite simple

But I have messed things up there

lyxal

@Wasif inside the flask app and as a function

A username

07:22

Hmmm, this is interesting. The thing is, looping is going to be a bit of an issue. Your looping implementation doesn't work for nested loops, and since you have an IP, being able to jump out of a loop is going to be a real pain.

lyxal

I know that my case is a bit more complex than yours, but the concepts are the same

Wasif

@Ausername it worked for nested loops to me

Things like {{i}d} (outputs 90) work properly

lyxal

what is s=sys.stdin.read() for?

wait is that the program?

Wasif

@lyxal yes, I couldn't see any other reasonable way to take input until now

@Wasif Nvm, got mixed up.

That's honestly quite clever.

Where can I find a fast C implementation of a priority queue?

@Anush Do you want a ready to use library, or just somewhere to draw implementation inspiration from?

Wasif

@lyxal thanks!!

lyxal

Eh, don't thank me yet. The site design is a plain rip of Vyxal, and I didn't test it

But chances are that it will work

Work unmodified that is

Wasif

@lyxal I would modify it later

I need to learn about flask more before that

lyxal

reccomended resource: digitalocean.com/community/tutorials/…

It helped me

so it'll help you too

Anush

@pxeger I want to use it

pxeger

no suggestions then, sorry

Anush

:( it's crazy that such a standard data structure has to be rewritten in 2021

pxeger

that's C for ya

Anush

I think google has hash table code that is fast

and glib I think has C code for some things.. but I don't know if either provide a priority queue implementation

pxeger

@Anush github.com/google/highwayhash?

Anush

08:25

@pxeger that's a hash function

I need a priority queue

ngn

@Anush it should be easy enough to implement it yourself

pxeger

@Anush I know, but I wanted to know if that's what you were referring to

Anush

@ngn yes but I want it to be fast and I am not you :)

@pxeger yes

developer.gnome.org/glib/stable/glib-data-types.html so close"

pxeger

@Anush github.com/LeoVen/C-Macro-Collections#available-collections - this has a heap; will it suit your needs?

Anush

@pxeger ooh it could do! This is a little frustrating bugzilla.gnome.org/show_bug.cgi?id=575074

did it actually get added to glib or not?? I can't tell even though I read the whole thing

pxeger

08:34

@pxeger There are more like this here: github.com/oz123/awesome-c#data-structures

@Anush doesn't look like it, no

Anush

thanks @pxeger . I just read "In the 17 years since this issue was opened, nobody’s provided examples of three applications which would benefit from a priority queue implementation in GLib, as per our rule of three, so I’m going to close this. While priority queues are neat data structures, they’re probably a bit too specialised for GLib, and are better implemented in the one or two applications which need them.
" :(

I am tempted to pose a challenge for the shortest code that is faster than C's qsort

heapsort usually isn't faster than qsort. it doesn't have good locality.

@pxeger how about without exec?

Anush

Oh well, I'll keep it then ask later.

Wasif

09:01

@Ausername actually it is intended to push the IP outside the parentheses in right direction so I decided on that

lyxal

@Ausername That would require a purely alphabetical quine

I don't know if that is possible

A username

What can we do with what we have? Lots of constants, that's for sure

And eval...

No strings so assembly is required...

@Wasif Ok. Also, your X and Y variables are mixed up and you've got a a redundant execute=True in the loop.

Wow I am bad at spelling...

but if they provide a particularly good robber's answer, I might give a bounty

and the biggest reason I put the bounty on the previous one was because the question was kinda dead so I was worried noone would try

A username

@Wasif Soory I took so long, here you go. The interpret function is all you need. It takes program as a string, input as a number, and an output function which is called whenever it wants to output something.

The rest is a demo 'roll a dice' program

BTW really nice trick with the times *= 10 for loops.
