This is a random array generator in APL

Destructible Watermelon

halts if inputted CT program halts

ASCII-only

@MicroTransactionsMatterToo Random array?

MicroTransactionsMatterToo

Array of random numbers

?¨(⍺⌿(?⍵)): Minimised

Within given range, and length

ASCII-only

@MicroTransactionsMatterToo As input?

MicroTransactionsMatterToo

11:02 AM

Hmm?

ASCII-only

Range and length are inputs?

MicroTransactionsMatterToo

⍺ and ⍵ are APL argument placeholders

Yes

They're arguments

Or inputs

If wanted

Woops, looks like it's broken

I'll try to fix it

Oh, never mind it works

It uses the range arg as an upper bound

Use is, len randArray range

tryapl.org. Paste this first randArray←{(?¨(⍺⌿(?⍵)))}, then something like 400 randArray 30

ASCII-only

Charcoal doesn't do too badly, and wasn't even supposed to be golfy for numbers (btw by default numbers are printed as lines since this is ASCII-art-focused, here is a more readable one

First input is range, second is number

MicroTransactionsMatterToo

Cool

HTML Tag remove (Not mine, off wikipedia, but still cool) : ⎕←{⍵/⍨~{⍵∨≠\⍵}⍵∊'<>'}txt

It's also system functions, like ⎕LOAD

I was thinking of making a language: Turtlèd but golfy

ASCII-only

11:11 AM

@DestructibleWatermelon That's what Charcoal is supposed to be

Destructible Watermelon

not exactly

very different really

MicroTransactionsMatterToo

Luckily with golfing languages, the need for AST's seems considerably lesser than a normal language

It's false for languages with exotic parsing rules, like Jelly

MicroTransactionsMatterToo

false?

ASCII-only

@MicroTransactionsMatterToo No

For stack-based languages, yes

ASCII-only

@MicroTransactionsMatterToo Charcoal has an AST

MicroTransactionsMatterToo

Yes

I said lesser

Not unneeded

ASCII-only

Lesser? Not at all

TuxCopter

gtg bai

MicroTransactionsMatterToo

To an extent, some AST is always needed. Whether it's actually needed in that form is a different matter

Could just be an if, else if in a parser

ASCII-only

11:15 AM

It only applies to stack-based esolangs, and those are becoming scarcer and scarcer. Of course, for the majority of other languages like Jelly which have very few different types of constructs, an AST does not actually need to be constructed

MicroTransactionsMatterToo

For instance, Brainfuck loops. They loop if the current cell is not zero. You could use an AST model, or just an if clause

Yeah

ASCII-only

@MicroTransactionsMatterToo ASTs aren't needed, just they make things easier the more complex your language's syntax is

MicroTransactionsMatterToo

I know

Destructible Watermelon

I didn't need an AST or something

MicroTransactionsMatterToo

kk

I'm used to writing parsers for larger languages

Would parsing a MIDI data stream be a decent challenge?

ASCII-only

11:18 AM

Maybe? If it isn't super complex, it should be fine, but be careful and make sure there aren't any other similar (i.e. MIDI-based) challenges before posting

MicroTransactionsMatterToo

There actually aren't any libraries in a majority of languages for parsing MIDI files

There is one for C/C++

And none at all for python, that actually work

ASCII-only

@MicroTransactionsMatterToo :P

MicroTransactionsMatterToo

It's kinda annoying

I'm writing one in Dart and Python at the mo

ASCII-only

If you want decent code, maybe make it a fastest-code and encourage submissions in all languages?

MicroTransactionsMatterToo

Yeah

I would have to limit it to normal Note/Polyphonic events

There are too many in the full spec

Or maybe just a challenge for parsing a MIDI delta time. They're variable length

@MicroTransactionsMatterToo Why work on it when there's Google Translate?

MicroTransactionsMatterToo

Google translate is absolutely terrible at Maori

ASCII-only

11:29 AM

+1 though, I can never get myself to focus on one project

MicroTransactionsMatterToo

It's literally never right

ASCII-only

@MicroTransactionsMatterToo Yeah, but it's getting better (slowly...)

MicroTransactionsMatterToo

Google Translate is ML based, and as there is bugger all material online in relation to the Maori language, it doesn't do well

And the Maori material on the internet isn't increasing very fast

Anyway, people don't use Google Translate for Maori, cause they know it's wrong

So, Google doesn't get any new data

ASCII-only

Hmm

MicroTransactionsMatterToo

The nice thing about Maori, is that it follows it's own rules rigidly, meaning we can use a rule based system for translations

ASCII-only

11:33 AM

Why did Google even add Maori then?

MicroTransactionsMatterToo

Google has added just about every language they know of

But they didn't really commit to any of them

It was an experiment at first i think

It just kinda grew

HDL quine (is it possible at all?) I have the following idea: Write a program in a hardware description language (e.g. VHDL, Verilog ...) which can be executed on a programmable logic device (CPLD, FPGA ... or only simulated on a PC, of course) and outputs its own source code (e.g. Verilog code...

MicroTransactionsMatterToo

Cool

I wish HDL langauges were easier to work with

ASCII-only

@MicroTransactionsMatterToo rules = grammar?

@MicroTransactionsMatterToo No, in general they don't add a language until they have a sufficiently large corpus to provide decent translations

@MicroTransactionsMatterToo Maybe, but it doesn't really explain why there are so many other translation services other than Google's

MicroTransactionsMatterToo

Dunno then

Maybe it's because there is enough on the internet to get a general idea, but not enough to be accurate

They translate everything with the same tense,

The words are generally correct, but order and non-direct translations of words (things like and, a and it) are all wrong

ASCII-only

11:37 AM

How are you going to do the English -> Maori translation?

English is literally the worst language to parse

MicroTransactionsMatterToo

We're using a lib called NLTK to deal with the English side of things. The maori side of things is done by creating rules that either infer meaning/context from words in the sentence, or directly asks the user

NLTK is a beautiful piece of work

If we didn't have it, the project wouldn't be happening

Anyway, the original prototype got to about %98.7 accuracy if the user response was correct

I'm working on making it into an extendable framework, and creating a web interface for it

Pretty good going considering I'm only 14

We got the whole thing verified by the leading Maori linguist. He said he thought it was awesome

Ironically, the rest of the team is French

ASCII-only

@MicroTransactionsMatterToo In PPCG "pretty good" means something different than outside PPCG :P

MicroTransactionsMatterToo

Oh, what does it mean?

ASCII-only

Well, we kinda have different standards

MicroTransactionsMatterToo

Oh, what would that mean?

As in, how would these different standards affect that statement

ASCII-only

11:45 AM

Not too much, I guess?

MicroTransactionsMatterToo

Ok, thanks for the heads up though

Anyway, I meant "Pretty good" in general. There aren't too many 14 yr olds working on a full-scale translation framework (Correct me if I'm wrong)

ASCII-only

Almost everyone here has made at least one esolang, and we have a significant fraction of <20 year olds - there have been some amazing projects e.g. Downgoat/Conor have been writing a non-esolang (Also El'endia/quartata on another one)

MicroTransactionsMatterToo

Yeah, that's cool

Qwerp-Derp

Hello!

MicroTransactionsMatterToo

Although, I feel an Esolang, depending on what it is, wouldn't neccesarily be to hard to create

Qwerp-Derp

11:47 AM

@ASCII-only How to make web server thing?

@MicroTransactionsMatterToo Not true for some esolangs...

MicroTransactionsMatterToo

I know

I said depending on what it is

ASCII-only

@MicroTransactionsMatterToo They wouldn't be easy either

Qwerp-Derp

They wouldn't be too hard with a pre-made parser

MicroTransactionsMatterToo

Yeah, I realise that

However, something like Brainfuck isn't hard to implement

Implementing it to be as Turing Complete as possible, is a different problem

Befunge, on the other hand, would be somewhat tricky to parse

Qwerp-Derp

What do you mean "as Turing Complete as possible"?

It's pretty binary if you ask me

MicroTransactionsMatterToo

11:49 AM

Well, a Turing Complete language is limited only by the thing it runs on

So, it would really just be accounting for that

Yacc is a similar idea

MicroTransactionsMatterToo

Yep

ASCII-only

bison = super hard to understand

MicroTransactionsMatterToo

I played with it a bit, but got confused. Was a while ago though

Yeah, it's weird how it represent a literal AST using text only

Seems like it would make more sense to have a more programmatic approach to the representation

As in, I feel like Bison's AST structure wouldn't be easy to parse in and of itself

NodeJS is good for web devs

Cause it's just JS

Dart is good for those familiar with C-type languages

Python is python

@ASCII-only The AST thing I was talking about was my earlier comment on Bison

ASCII-only

... Almost every language is C-derived (including JS, and to a lesser extent Python)

Yes

But I mean, those familiar with C more than a dynamically typed language

Dart is not necessarily typed, but benefits from it

The "fin-above-water" thing is fairly common, at least near the shores here in Florida. Probably because it's shallower than usual, but it's rare I go to the beach without at least seeing one, even if its a small one.

@Geobits Are people who live near the beach usually more aware of the fact that shark attacks are actually really rare?

Geobits

2:45 PM

Yeah. Most people don't bother getting out unless it's a big one.

But the big ones are rare.

Nathan Merrill

@Geobits well, the shark, being in an "laser-like" state, I'd call them laser sharks, making the weapon laser shark laser

Geobits

IIRC, nurse sharks are the most common bites around here, but that's mostly because they hang out on the bottom, so people don't know they're there and step on them or kick them.

El'endia Starman

Man, those sharks are bad nurses. </probably-old-overused-joke>

@NathanMerrill And if you give one of those to a shark, you'd have a laser shark laser shark.

and then we'd actually have to be scared of sharks
