The Nineteenth Byte

8:01 PM

It's funny. nearly the entireity of QUARK's first half of the codepage (There are 3 halves now, i've moved to 10 bit encoding to allow even more shenanigins, and some dedicated optimization hints) is for variations of the alphabet, a few basic symbols, and 6 combining modifiers. Oh, and 5 repeats of the alphabet, with 3 of them just being the alphabet with some modifier tacked on

notably, a repeat of the alphabet and some symbols are given the e̲ modifier directly, to allow aliasing them as strings. QUARK now has two ways to make strings: u̲n̲d̲e̲r̲l̲i̲n̲e̲d̲ text and the usual quotes

@moonheart08 not enough arrows :P

moonheart08

?

Οurous

@moonheart08 You can never have enough arrows in a code-page. -> Not enough arrows.

moonheart08

lol

i'm using arrows to represent the various loop types, is that good enough? :p

Οurous

8:45 PM

@moonheart08 I guess. But then again what do I know, 1/5th of Dirty's codepage is arrows.

moonheart08

lol

QUARK's new codepage (which i'm still building) actually has some codepoints assigned to entire strings of characters

for example, 0BA is }1↻ (End block, while not 1 loop)

caird coinheringaahing

So it's tokenised (TI-Basic esque)

Οurous

Is that "OBA" -> "}1↻", or 0xBA -> "}1↻"

moonheart08

Yea.

@Οurous 0x0BA. 10 bit codepage

Οurous

Ooooh neat

moonheart08

8:47 PM

0x000 through 0x2FF

Tokenization has tons of advantages, and i'm mixing it with a compiled golfing language

caird coinheringaahing

Choosing 2^10 different characters for a code page must be really difficult :P

moonheart08

@cairdcoinheringaahing hence why i chose to have some be tokens

plus, QUARK has some quick tokens to make stuff like strings take up less space, so things like the alphabet and some symbols have multiple repetitions, eating up codepage space :P

I'm being really liberal with my space usage

And for tokenizations i can't just fit in the codepage, you have parser/compiler quicks

for example, i̐ is the compiler quick used to tell the compiler optimization hints

(and also tell it what arch to target for some code blocks, if thats possible. But that's for later)

main point of me allowing embedding code for other archs is to potentially allow GPU accelerated QUARK, just to make it better at performance challanges. I've decided i wanted to focus on performance for my redo.

because by allowing the arch target to be set, you can have a codeblock target SPIR

and as QUARK has some lowlevel qualities, stuff like pointer to function can be used to use said SPIR for GPU shenanigins, if i add support for that

Οurous

@moonheart08 so golflang with inline assembler?

moonheart08

9:02 PM

@Οurous Somewhat. I don't know if i'm actually going to allow inline ASM, due to unpredictability of the program's resulting structure lol

Οurous

@moonheart08 if Clean's inline ABC, which you can then inline ASM in has taught me anything, it's that you can always inline ASM. Even where it makes no sense.

moonheart08

lol

The first page is getting pretty full with variations of the alphabet lol imgur.com/CqPj0iJl.png

@moonheart08 combining characters in a codepage for a golflang?

@Riker lool :D reddit at its finest

Οurous

@moonheart08 is it starting compiled, or initially interpreted and then compiled later?

moonheart08

@Οurous Starting compiled. Old design for QUARK was interpreted. Interpreted can come later tho, LLVM has the ability to interpret IR

(Altho, it can't always do it. It depends.)

flawr

@moonheart08 make a case by case analysis for a one digit number

then do it for every digit by considering the remainder mod 10, then dividing the original number by 10 and again modding etc

moonheart08

Doesn't sound the fastest, but it'll work for an initial implementation.

flawr

writing a new language?

moonheart08

New golfing language, yea. It's a compiled one, and i want to avoid using the C std for too many things (Some things CAN use it tho), mostly because i'm not using null terminated strings.

; matches the ";"
your second capture group (.+) matches "<space>x"
the \2 matches "<space>x"
Now we repeat the first capture group but this time match "<space>y" for both
there aren't any characters left, so the $ matches the empty string at the end.
Does that make sense? I haven't used sed in a little while.

@seshoumara Hi to you too. I haven't seen you here in a long time (might be because I'm not very active anymore)

seshoumara

really nice to see you

yeah, since I got a new job in a company, and moved as well my free time has sunked

I browse new questions, but never have the time anymore to write answers

Riley

I just got moved to a new project that's behind schedule and have been working a lot of extra hours. I worked my first Saturday last weekend.

I don't even have time to follow new questions anymore :(

seshoumara

10:13 PM

back to my ex, if \1 matches " x x", how come it also matches after that " y y"??. I have \1* basically.

Riley

I think it's matching " x" not " x x". it's closer to <string1><string1><string2><string2> I think.

On the second time through (from the * at the end) it captures a new string.

seshoumara

even so, it should only match after that only multiple of xs, or how I envisioned, multiple pairs of xs

moonheart08

Well that kinda sucks. There are no maintained/stable LLVM bindings for rust

I have to manually handle unsafe code ):

seshoumara

but it's not a s statement with g modifier, that would do it too, the regex has a start ";" and an end "$". This capturing of a new string in what is to my mind \1* is confusing me

Riley

g would just allow the whole pattern to match multiple times across the line.

The * basically makes this /;(.+)\1(.+)\2/p

\2 is overwritten the next time (.+) is matched.

This will print " y":
echo "; x x y y"|sed -r 's/;(( .+)\2)*$/\2/'

also yeah

Explanation
(       )* more than one of:
 ( .+)     space + thing
      \2   space + same thing

seshoumara

which I took it as (space+thing+space+same thing) zero or more time

so " x x y y " should not have matched, only " x x x x"

that's my dilema

so the regex itself inside ()* is actually replicated, not what that regex first matched, which in my case it was " x x"?

Destructible Lemon

@ASCII-only * isn't more than one of

ok so

ASCII-only

go scroll up for the actual regex

Destructible Lemon

10:47 PM

(( .+)/2)/1* works?

seshoumara

my regex was ;(( .+)\2)*$

Destructible Lemon

also that matches ` x x y y` because it can match just one

except for the ;

seshoumara
