The Nineteenth Byte

I'm only accessing a handful of members at a time. by keeping track of the attributes myself, I can strictly define what I want as opposed to using what other people may have modified.

Zwei

whelp, I got translating brainf*** programs to vim keystrokes working somehow. Vim is turing-complete I guess

TùxCräftîñg

so you want to prove the turing completeness of vim ಠ_ಠ

quartata

5:08 PM

@Zwei Somewhere floating in the abyss that is Usenet there is an ancient Turing machine simulator in vim

Pretty cool stuff

Zwei

like the turing-completeness of vim was a surprise, though

TùxCräftîñg

i think you can fill the buffers with lines 0\n0\n0\n0... for the memory, the memory pointer is the cursor Y position

Zwei

yup, exactly what I did

quartata

@Zwei Not really. It's pretty obvious that it can do tag systems at least

TùxCräftîñg

and you can use vim math operations to increment

Zwei

5:08 PM

yup

TùxCräftîñg

for the loops i think recursive macros

or any other form of loops

Zwei

and then I used recursive macros ending with :if getline('.') != '0' | exe 'normal @q' | endif<CR> for the loops

TùxCräftîñg

but input and output ¯\_(ツ)_/¯

Zwei

I haven't got I/O working yet, but I figure you could use 3 tabs

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata that's true

Zwei

5:10 PM

one for the input bytes, one for the tape, and one for the output bytes

zyabin101

Hello, World! teletext page :3

TùxCräftîñg

@zyabin101 what is that?

quartata

@Mego haha

zyabin101

@TùxCräftîñg This is a teletext page (Mode Seven, of course) that says "Hello, World!" in its content (the second row).

Zwei

if it means anything, I got >+>+>++++<[>[-<+++++>]<<]> converted to vim keystrokes. Dealing with nested loops is what appears to have caught up other people that tried to convert brainf*** to vim. It did place 106 on the second line, which is a great start

Cᴏɴᴏʀ O'Bʀɪᴇɴ

5:13 PM

nested loops are hard

TùxCräftîñg

dont have vim, cant find a version working on windows :/

Cᴏɴᴏʀ O'Bʀɪᴇɴ

TùxCräftîñg

I do prefer it over vim while on linux, though

Dr Green Eggs and Iron Man

@TùxCräftîñg it doesn't work in the terminal, you need nvim-qt.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

6:06 PM

I used quotes :P

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ So how does that work in this case? Does it fill in every argument?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata that would be fn.reflexive. fn.rflx simply duplicates its arguments and applies it to the core function

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ So it's not ~?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata rflx is ~.

cheddar> fn.rflx((*))(3)
9

quartata

But how does it work for things greater than dyads

Cᴏɴᴏʀ O'Bʀɪᴇɴ

6:07 PM

   *~ 3
9

@quartata fn.rflx(func)(args) = func(...args, ...args) In this case, fn.rflx(IO.sprintf)('string',@"39) is IO.sprintf('string',@"39,'string',@"39)

So, %s%s%s is the quote, then the string, then the quote.

quartata

@CᴏɴᴏʀO'Bʀɪᴇɴ OK, so if I had a function that takes three arguments it wouldn't fill in the third

TùxCräftîñg

is there a autoexec.bat equivalent for win10?

because running chcp 65001 each time i launch cmd is silly

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@quartata if you want auto fill, fn.reflexive(f)(arg) fills the arguments with arg. I forget how it handles multiple args.

if it doesn't already, I'll make it fill.

quartata

What's the difference between fn.reflexive and fn.rflx

Cᴏɴᴏʀ O'Bʀɪᴇɴ

fn.reflexive fills to number of expected arguments. fn.rflx duplicates args.

@TùxCräftîñg what does chcp 65001 do?

TùxCräftîñg

6:12 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ set cmd to unicode 'codepage'

TIL %USERPROFILE%

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ Got a more concrete example?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@El'endiaStarman you familiar with JS's String.fromCharCode?

El'endia Starman

The name seems self-explanatory.

Is it like Python's chr()?

TùxCräftîñg

@El'endiaStarman yep

Cᴏɴᴏʀ O'Bʀɪᴇɴ

String.fromCharCode(num1[, ...[, numN]])

okay?

TùxCräftîñg

6:29 PM

but this is very verbose

like everything in javascript ಠ_ಠ

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@TùxCräftîñg that's false.

El'endia Starman

@CᴏɴᴏʀO'Bʀɪᴇɴ Oh, optional number of arguments?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@El'endiaStarman When you try to do [32, 33, 34].map(String.fromCharCode), you end up getting String.fromCharCode(element, index, array).

F(String.fromCharCode, 1) would "limit" the arguments to the first.

LegionMammal978

@CᴏɴᴏʀO'Bʀɪᴇɴ New feature: d takes the X, Y, radius, and color and creates a filled disk

Cᴏɴᴏʀ O'Bʀɪᴇɴ

So you could do something like [32, 33, 34].map(F(String.fromCharCode, 1))

@LegionMammal978 oo, nice!

El'endia Starman

6:31 PM

@CᴏɴᴏʀO'Bʀɪᴇɴ Oooh, okay, I can see how that would be useful.

feersum

fromCharCode takes 3 arguments? What sort of abomintaion is this?

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@feersum takes N arguments.

> String.fromCharCode(32, 33, 34)
' !"'

A call from map passes three arguments--element, index, array.

feersum

So the problem is that map is broken?

El'endia Starman

...oh, that's messed up. And makes sense. And wasn't well-thought-through.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@feersum There is no problem.

@El'endiaStarman why? it makes perfect sense.

El'endia Starman

6:34 PM

I can see why you might like to pass the index and array to the function you're mapping, but to do it by default indicates a lack of foresight. The function should just be applied to each element, period.

feersum

I should know by now but I can't help being ever shocked anew by the deranged design of JS.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

prefixes = (array) => array.map((e, i, a) =>
    a.slice(0, i + 1)
)
> prefixes([1,2,3])
[ [ 1 ], [ 1, 2 ], [ 1, 2, 3 ] ]

Because it isn't what you usually use doesn't mean it's bad--in fact it's very useful.

TùxCräftîñg

found a workaround for the chcp problem: configure cmder to launch bash instead of cmd

feersum

How sane languages do it: In Python if you want both the index and element you do map(f, enumerate(a)). In Ocaml you do List.mapi f a.

Whereas you use map f a if you don't want the index.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@feersum what does enumerate do? it looks long and unnecessary.

El'endia Starman

6:39 PM

>>> s = "hello"
>>> for i,k in enumerate(s):
	print(i,k)


0 h
1 e
2 l
3 l
4 o

LegionMammal978

I mean, <array>.map((e, i) => ...) or even <array>.map(e => ...) still work

TùxCräftîñg

@CᴏɴᴏʀO'Bʀɪᴇɴ enumerate([1, 4, 6]) return [(0, 1), (1, 4), (2, 6)]

LegionMammal978

It just ignores the rest of the arguments

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@TùxCräftîñg ninja'd

@LegionMammal978 And that's wrong.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@feersum What you perceive to be write only is irrelevant ;)

feersum

feersum

Cᴏɴᴏʀ O'Bʀɪᴇɴ
