[harsh junco]

What are notable differences between Apple Clang and original clang?

[reef trail]

using it there’s any much difference, all it does it let apple tweak things for them

[faint timber]

arm64e abi is closed source!

[reef trail]

that’s the main problem yeah

[proud geyser]

question is how does one decode hs256 signed jwt token in swift

[reef trail]

might be what you're looking for https://github.com/auth0/JWTDecode.swift

[proud geyser]

doesnt support hs256 decoding

[reef trail]

looks like it does?

[proud geyser]

doesnt mention it anywhere on docs..?

[reef trail]

it does in the source code

[placid kraken]

@radiant idol

[proud geyser]

theres just 3 files..? of code

[proud geyser]

thanks for new pfp 👍🏼

[placid kraken]

OMG

what else do you need to know

[radiant idol]

???

[placid kraken]

idk i found it cute and thought i’d send it to you 😭

[radiant idol]

I just woke up

That’s why I’m super confused

[placid kraken]

oh lmaoo

fair enough

[reef trail]

i just searched for hs256 on the gh and it found it

[vivid dew]

jwts are not real

@slender glade

[slender glade]

sorry for not replying to the others I was not doing well

also that question looks like some "the final exam is just one question" bs lol

where do u even start

[placid kraken]

lmao don’t worry about it

[placid kraken]

i didn’t solve it but

this is what the person did

)horror)

i have no clue how i would do it either

[slender glade]

DUDE WHAT

that is INSANE

[placid kraken]

YEAH

LMAOO

[slender glade]

i feel like throwing up fuck you rosie

[placid kraken]

sowee

[slender glade]

start worrying NOW.

[placid kraken]

are u in my walls?? 🥺

[slender glade]

No because I'd have to make a mathmetical equation to find you in the first place

[placid kraken]

lmaoo true

[slender glade]

im still just like

[placid kraken]

my full phone number is hidden in the digits of PI go and find it

[slender glade]

idek if shock is the right word

[slender glade]

mine is in Euler's number

0!=1 proof is easily the most fun thing i've ever written

[placid kraken]

i like my proof of 0.99999… = 1

[slender glade]

🥹

proofs make me happy

[placid kraken]

it’s not approximately 1 or almost 1 it is EXACTLY 1

which is why it’s fun

[slender glade]

the set explanation is most fun

[placid kraken]

true

[slender glade]

what's bigger than 0.9 in 0.999....

0.99

and what's bigger than 0.99 in 0.999...

etc

till u get to the supremum of 1

[placid kraken]

there’s also that one proof that says “you can’t fit any number between 0.9999… and 1 so therefore they must be identical”

[slender glade]

huuu

I have not heard of that proof before

do you have a link to an image or technical explanation?

[placid kraken]

yeah it’s on wikipedia iirc

[slender glade]

FUCK

wrong

I meant the peak emoji

[placid kraken]

https://en.m.wikipedia.org/wiki/0.999...

[slender glade]

lemme see

[slim bramble]

Anyone knows how many instructions there are in aarch64 ?

[slender glade]

a lot

[placid kraken]

but then the question becomes @slender glade

[slender glade]

becomes me

[placid kraken]

0.4999999…

do you round up or down

[slender glade]

UP

WHY WOULD YOU ROUND THAT DOWN

@placid kraken I wonder if computers have a special case for 0 factorial

[placid kraken]

because even though it’s exactly 0.5 it looks like less

[slender glade]

ie if (input == 0) return 1;

[slim bramble]

[slender glade]

why would you round down in any case here?

i mean it does look less

but so does 0.999...

[placid kraken]

true

[slender glade]

I also wonder how computers handle 0.999...

wait

im dumb

there is a bit limit

[placid kraken]

python gives me one

[slender glade]

my bad

[placid kraken]

for 0!

[slender glade]

mhm but like

logically

there's gotta be an if condition or smth because

the natural formula for factorial w 0 would give u 0

[placid kraken]

they would round to 1

[slender glade]

true..

[placid kraken]

because they round the last decimal place when it reaches the bit limit

[slender glade]

I'm so out of it lmao this is such basic stuff

this is what 24/7 bio studying does to a mf

[placid kraken]

and the last decimal place would always be a 9

[slender glade]

🤧 wonder how this works out for finance

[placid kraken]

and the 9 would bubble up the decimal places until it reaches 0 and makes it 1

[slender glade]

like, .99 prices

[placid kraken]

when are you ever gonna have to calculate a p-adic number in finance lmfao

[slender glade]

average tuesday for me

[placid kraken]

ah yes

please give me -5 oranges

give me 0.99999…. of them

[slender glade]

LMAO

[placid kraken]

give me PI of them

[slender glade]

omg i wonder like

if u set the price of a product on some e commerce site to pi

and then buy it

wtf happens

[placid kraken]

explosion

servers will crash

[slender glade]

[slender glade]

LMAOO

that cannot. be real

[placid kraken]

it’s the best fix i’ve ever seen

[slender glade]

my type of fix honestly

half joking

[placid kraken]

horror

[slender glade]

DONT tell me u wouldnt write a fix like that either

[slender glade]

also this is like

30% of how the entitlements system works

and it's kinda funny to think in that way

[placid kraken]

tbh i would

[placid kraken]

even worse

[visual meadow]

what the fuck do you mean bro

most useful resource gone

i just tried on cellular and it doesnt work either its broken

[placid kraken]

this is genuinely becoming so complicated

the parser and compiler are becoming longer and longer by the minute

the parser section ONLY FOR PARSING STATEMENTS is already 530 lines

because i need to handle literals, function calls, declarations, returning, declarative-likes (*= and +=), incrementing (both ++num and num++ work now)

and more

and there STILL arent any if statements yet

but

pub fn main() {
    Int a = 1;
    Int b = a++;
    printf!("a: %d, b: %d\n", a, b);
    // a: 2, b: 1
}

pub fn main() {
    Int a = 1;
    Int b = ++a;
    printf!("a: %d, b: %d\n", a, b);
    // a: 2, b: 2
}

we have incrementing !!!!!!!!!!!

the difference in the IL code is quite small lol

with num++

export function w $main() {
@start
    %tmp_1 =w copy 1
    %tmp_2 =w copy %tmp_1
    %tmp_3 =w copy %tmp_1
    %tmp_4 =w copy 1
    %tmp_5 =w add %tmp_3, %tmp_4
    %tmp_1 =w copy %tmp_5
    %tmp_7 =w call $printf(l $main_6, ..., w %tmp_1, w %tmp_2)
    ret
}
data $main_6 = { b "a: %d, b: %d\n", b 0 }

with ++num

export function w $main() {
@start
    %tmp_1 =w copy 1
    %tmp_2 =w copy %tmp_1
    %tmp_3 =w copy 1
    %tmp_4 =w add %tmp_2, %tmp_3
    %tmp_1 =w copy %tmp_4
    %tmp_5 =w copy %tmp_1
    %tmp_7 =w call $printf(l $main_6, ..., w %tmp_1, w %tmp_5)
    ret
}
data $main_6 = { b "a: %d, b: %d\n", b 0 }

Your UDID is banned

I’m kidding, doesn’t work for me either

[placid kraken]

craziest terminal ever

now i have to somehow figure out how im gonna pass a memory address to scanf lmfao

NO FUCKING WAY IT WORKS

ABKDKWABD

[placid kraken]

fn input(String message) -> String {
    String out = "";
    puts(message);
    scanf!("%s", out);

    ret out;
}

pub fn main() {
    String test = input("input pls? :pleading:\n");
    printf!("\ndid you say %s? that's so true bestie\n", test);
}

this works with no extra modifications to the language lmfao

it just works

[radiant idol]

wait

[placid kraken]

yes

out is a pointer

[radiant idol]

YOU DID MY ! PROPOSAL??

[placid kraken]

oh

yeah lmao

[radiant idol]

lets go

[placid kraken]

im not doing func tho

[radiant idol]

smh

fine

[placid kraken]

i started getting annoyed having to type out $...$ every time lmfao

[radiant idol]

isnt scanf insecure tho

[hasty ruin]

censorship.

[placid kraken]

btw the $...$ or ! syntax is actually mandatory lmaoo

[placid kraken]

it doesnt throw an error trolley~3

if i use gets i actually get a warning by macos

[radiant idol]

L

[placid kraken]

i would use fgets but i cant make file pointers yet / i dont know how via the intermediate language

[radiant idol]

make if statements

[placid kraken]

soon

this is what i was doing today

b = ++a -> a is 2, b is 2
b = a++ -> a is 2, b is 1

[placid kraken]

.

[radiant idol]

what happens if you put a binary generated by the compiler into a disassembler

[placid kraken]

actually i think ill make borrow checker first then ill do if statements

trolley~3

[placid kraken]

i mean the compiler generates assembly

we can just look at that directly

[radiant idol]

no I mean

would you be able to do pseudocode

I assume not

[placid kraken]

idk probably not

oh

no syntax highlighting

thats the asm for this

fn input(String message) -> String {
    String out = "";
    puts(message);
    scanf!("%s", out);

    ret out;
}

pub fn main() {
    String test = input("input pls? :pleading:\n");
    printf!("\ndid you say %s? that's so true bestie\n", test);
}

[radiant idol]

neat

[placid kraken]

i mean i suppose binary ninja generates this high level IL

but i dont think this is what you mean

its also missing some parts?

[radiant idol]

i meant ida

[placid kraken]

[placid kraken]

what’s the safe way of doing it..?

[gentle grove]

fgets i believe

i can't remember

something with a set length so you dont risk buffer overflow

[torn cloud]

and what

[sonic totem]

Meant to tag @granite frigate

[kind herald]

troll installer 17 poc by project zero bug jailbreak

[placid kraken]

ok do you know how to open an stdin file pointer tho

i already tried using fgets but i’m not sure how to open a file pointer with it in the IL lmao

[gentle grove]

does it not work to use stdin like normal

like from stdio.h

[placid kraken]

oh uhhhhhhhhhhhh

about that

[gentle grove]

what lang are you using

i am not up to date on the context

[placid kraken]

my own

[gentle grove]

oh that's an issue

[faint timber]

fopen?

[placid kraken]

it has a compiler backend with c bindings

but

fn input(String message) {
    String out = "";
    puts(message);
    scanf!("%s", out);

    ret out;
}

pub fn main() {
    String test = input("input pls? :pleading:\n");
    printf!("\ndid you say %s? that's so true bestie\n", test);
}

[placid kraken]

yeah that would be great.. if i could hold a file pointer

[gentle grove]

implement a way to do real c ffi so you can access the stdin symbol

and then like a real standard library, wrap it in a safe interface for the rest of the language to use

[placid kraken]

im pretty sure it has real c ffi im just not sure how to access the symbol

[gentle grove]

its just a symbol in the header isnt it

[placid kraken]

from the intermediate language

[faint timber]

Why can you not have pointers?

[gentle grove]

or i guess something has to be executed for it to be poopulated

idk how it works on this level

[faint timber]

You make java or some shit?

[placid kraken]

i didnt import any headers and methods like printf, scanf, gets, fgets, fopen, puts, etc are just defined globally

[placid kraken]

i mean i can technically have pointers

otherwise scanf wouldnt work

[native orbit]

cant u just call read() with fd 0

[gentle grove]

does libc populate the stdin

and youre not executing the code in libc?

is that how this works normally

[faint timber]

I thought it wasn’t inherently going to be 0, 1, 2?

[gentle grove]

time to clone musl

i will not be reading glibc

[placid kraken]

im not sure whether qbe runs libc internally, i assume it does

the assembly generated is just bl _printf so when assembled with clang i assume it runs libc

[gentle grove]

well it looks like musl sets it to 0

#include "stdio_impl.h"

#undef stdin

static unsigned char buf[BUFSIZ+UNGET];
hidden FILE __stdin_FILE = {
    .buf = buf+UNGET,
    .buf_size = sizeof buf-UNGET,
    .fd = 0,
    .flags = F_PERM | F_NOWR,
    .read = __stdio_read,
    .seek = __stdio_seek,
    .close = __stdio_close,
    .lock = -1,
};
FILE *const stdin = &__stdin_FILE;
FILE *volatile __stdin_used = &__stdin_FILE;

src/stdio/stdin.c

[placid kraken]

just i seem to only have the methods in stdio.h and not everything else

[placid kraken]

slight issue: i havent implemented structs yet

lmfao

[gentle grove]

well you dont need to if you can call the methods to deal with it

since its an opaque type

[placid kraken]

ah true

[gentle grove]

also you should probably implmeent actual C ffi at this point

[placid kraken]

yeah i probably will

seemingly

(i dont know how)

[gentle grove]

what is qbe

[placid kraken]

its a compiler backend like llvm ir

but the intermediate language is a little simpler

[placid kraken]

for example this code is turned into this intermediate language code

function l $input(l %message_1) {
@start
    %out_2 =l copy $input_3
    %tmp_4 =w call $puts(l %message_1)
    %tmp_6 =w call $scanf(l $input_5, ..., l %out_2)
    %r_v6_7 =l copy %out_2
    ret %r_v6_7
}
export function w $main() {
@start
    %tmp_10 =l call $input(l $main_9)
    %test_8 =l copy %tmp_10
    %tmp_12 =w call $printf(l $main_11, ..., l %test_8)
    ret
}
data $input_3 = { b "", b 0 }
data $input_5 = { b "%s", b 0 }
data $main_9 = { b "input pls? :pleading:\n", b 0 }
data $main_11 = { b "\ndid you say %s? that's so true bestie\n", b 0 }

[acoustic imp]

@radiant idol, (sense i had to deal with MRU stuff for jade) what like the best way to know when media is paused/playing ?

[hasty ruin]

do you want to know when it's paused/playing, or if?

[acoustic imp]

if

need to know whne chnaged and i can plod jus use MRU api thing

nvm

[tired meteor]

its an bin file

[acoustic imp]

figured it out

[radiant idol]

I don’t even know at this point, MediaRekote is so cursed that I try to not even touch it

[tired meteor]

looks like assembly code

[acoustic imp]

[SBMediaController isPlaying] 💪

[hasty ruin]

careful with that

some parts of SBMediaController break if you respring by killing sb

[acoustic imp]

?

wdym? like it just stops working?

[hasty ruin]

some stuff returns nil

ik the active now playing app does that

so i had to use MRMediaRemoteGetNowPlayingApplicationPID in rune

which doesnt have that issue

[acoustic imp]

well i mean im only gona be using it when the LS player is on screen so do i still need to worry?

[hasty ruin]

i mean

try it

[hasty ruin]

#jailbreak message check its parent message for more info on the issue too

[acoustic imp]

@hasty ruin

[hasty ruin]

now sbreload

does it work

[acoustic imp]

Well yea it will bc that kills everything

And when u start playing music again it like will refresh

[hasty ruin]

MRMediaRemoteGetNowPlayingInfo(dispatch_get_main_queue(), ^(CFDictionaryRef information) {
    if (CFDictionaryContainsKey(information, CFSTR("kMRMediaRemoteNowPlayingInfoPlaybackRate"))) {
        float playbackRate = 0;
        CFNumberRef playbackRateRef = CFDictionaryGetValue(information, CFSTR("kMRMediaRemoteNowPlayingInfoPlaybackRate"));
        CFNumberGetValue(playbackRateRef, kCFNumberFloatType, &playbackRate);
        bool isPaused = (playbackRate == 0);
        // ...
    }
});

ok try that

may be overcomplicated but if it works...

[acoustic imp]

Hol on I was jus playing around on my phone one sec

makes sense il try

[radiant idol]

it's mediaremote

[hasty ruin]

void MRMediaRemoteGetNowPlayingInfo(dispatch_queue_t queue, MRMediaRemoteGetNowPlayingInfoCompletion completion);```

[radiant idol]

everything is overcomplicated

[hasty ruin]

true

[acoustic imp]

oops didn't see that one

its just retuns a bool right ?

[hasty ruin]

oh theres a decicated thing for it

cool

[acoustic imp]

idk how to use it tho ur thing didnt work either

[hasty ruin]

whats the issue

[acoustic imp]

well hteres this thing to

but idk which to use

i tried the second and just like replaced what needed to be in what u sent but that didnt work

       MRMediaRemoteGetNowPlayingApplicationIsPlaying(
        dispatch_get_main_queue(), ^(Boolean isPlaying) {
            //if (isPlaying != nil) {
                return isPlaying;
            //}
    });```

ik im dumb but like idk

@hasty ruin

?

[timid furnace]

no known conversion from 'Boolean (^)(Boolean)' to '__strong MRMediaRemoteGetNowPlayingApplicationIsPlayingCompletion' (aka 'void (^__strong)(Boolean)') for 2nd argument

[acoustic imp]

idk what that means

[timid furnace]

expected: void (^__strong)(Boolean)
given: Boolean (^)(Boolean)

notice a difference

[acoustic imp]

yes

but what does __strong mean ?

[timid furnace]

__strong is for ARC

it is irrelevant

[acoustic imp]

k

[timid furnace]

what's the other difference

[acoustic imp]

voic and bolen

[timid furnace]

there you go

[acoustic imp]

ohh i get it

thats anoying

or race condition

who knows

[acoustic imp]

Tis this “semaphore” you speak of

[sonic totem]

In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system.

[placid kraken]

semaphore is a synonym for traffic light

i think

its kinda like a mutex in rust

where you can .lock()

it sucks that i dont know any QBE wizards because that means i need to ask on a mailing list on sourcehut about it lmfao

(this is what im asking about if anyone has any idea what i can do)

which runs fine. As %out_2 is a pointer, passing it to scanf works. However, I would like to use fgets instead, as scanf doesn’t particularly handle strings with whitespace very well. The issue is that I’m not sure how to access the stdin file pointer from stdio.h, and as Elle cannot currently create opaque types I’m stuck on how to manually implement an stdin file pointer to pass to fgets without segfaulting.

[frail cedar]

No

It's the term for signal flags

Semaphore is the protocol to communicate via flag position n stuff

Before radios you could wave flags at long distances

They were used to communicate position info n stuff like that in battles

Apple's using the terminology to track start/stop stuff

[hexed knot]

Семафор (semafor) is macedonian for traffic light

They basically mean the same thing

[frail cedar]

Yea but it was originally for flag communication

[hexed knot]

Idgaf

[placid kraken]

yeah its also a thing in romanian

[placid kraken]

how the fuck do you use the in-reply-to header in an email

[cloud yacht]

This is too advanced, jailbreak developers don't have any original ideas, they just steal new iOS features, old tweaks that broke or mockups made by someone with some creative ability

[vivid dew]

it's true

i stole a new ios feature

[placid kraken]

i figured out how to get a file pointer to stdin thanks to the dev of qbe making me realise that i completely forgot fdopen exists

export function w $main() {
@start
    %out_2 =l copy $input_3
    %stdin =l call $fdopen(w 0, l $stdin_mode)
    %result =l call $fgets(l %out_2, w 2, l %stdin)
    %tmp_12 =w call $printf(l $main_11, ..., l %out_2)
    ret
}
data $stdin_mode = { b "r", b 0 }
data $input_3 = { b 2 }
data $main_11 = { b "\ndid you say %s? that's so true bestie\n", b 0 }

[primal perch]

thank you for your useful contribution to #development captain incorporated

[placid kraken]

yes the docs exist but i kept thinking to try and find how the backend exports the stdin symbol

as it turns out on windows its

extern FILE _iob[];
#define stdin  (&_iob[0])

on linux its

extern FILE *stdin;     /* Standard input stream.  */
#define stdin stdin

and on macos its

extern FILE *__stdinp;
#define    stdin    __stdinp

yes but you cant just reference the stdin global from the intermediate language

well its fine because fdopen(0) just returns a fp to stdin on whatever platform youre on anyway

i just need to mint it to use that stdin symbol whenever the code tries to access it, almost like faking a global i suppose

[torn oriole]

it is

[lethal kayak]

rust syntax is definitely better than objc

from a readability standpoint

[gentle grove]

its more utilitarian than ugly

people hate on rust syntax not realizing you have to still learn just as much new ssyntax for something like python vs c

[torn oriole]

not after that fuck up in #general you dont 😭

[hasty ruin]

But python’s syntax can be understood by just looking at it

[torn oriole]

its just slow as mollasses

[native orbit]

same with asm

[gentle grove]

and so can rust

you have to obtain the syntax knowledge

[hasty ruin]

mods misinfo

[gentle grove]

if you dont know python syntaxc then staring at it does nothing

maybe its a little more intuitive but still

[torn oriole]

this is false, i learned python

[torn oriole]

and thats saying something

[gentle grove]

if youre going for not knowing syntax then the point is void

[primal perch]

C++ syntax better than rust

will Apple allow special entitlements to emulators in the AppStore since jit is still not allowed

[opal ridge]

no unless you make a web browser with window.WebLoadMachO()

something ridiculous like that

so: no

[opal ridge]

or

there's a "com.apple.developer.cs.allow-jit" in 17.4

[opal ridge]

if apple really does not review content of apps on alternative app marketplace as promised:

[opal ridge]

1. get a bundle id approved for web browsing
2. actually publish normal web browser on app store
3. publish whatever app (example: livecontainer) with same bundle id and that entitlement on alternative app marketplace

but I feel that they are not going to strictly adhere to that

[opal ridge]

they say it's only review security and privacy issues but

the only times where that hasn’t happened was when i tried to borrow a mutable ref from a ref cell for internal mutability twice in the same macro

which throws a runtime error

[gentle grove]

i'm not an expert in this area but i'm pretty sure youre not supposed to do things that way

like they should communicate the size along wiht the pointer to you

or have a struct, or methods to deal with it if its like an opaque type

[placid kraken]

well fgets takes a buffer, max size of the input, and then a file pointer

[gentle grove]

what are you trying to get the size of

[placid kraken]

essentially just a section of 100 bytes or however many the user passes in

[gentle grove]

like the size of stdin?

[placid kraken]

uhhh no, fgets basically allows you to pass the max size of the input until it stops to prevent a buffer overflow

i want to make that max size the size of the buffer

[gentle grove]

i mean if youre statically allocating the array then you just put that same number in manually into the fgets call

[placid kraken]

i mean i guess so

i know sizeof is a runtime function

[gentle grove]

is it

[placid kraken]

yeah

[gentle grove]

google says sizeof is compile-time

oh unelss its a variable length array which is varargs or whatever i believe

[placid kraken]

sizeof is compile time for static arrays ofc

[gentle grove]

oh no

i havent ever used VLA before

i dont think i knew this existed

[placid kraken]

lmfao

[gentle grove]

i mean however youre declaring the size of the buffer, you just pass that same thing into fgets

[placid kraken]

fair enough i guess

[gentle grove]

if you dont know how big your buffer is then you have bigger structural problems

[vivid dew]

vlas aren't real

[gentle grove]

i agree

[placid kraken]

ok so i implemented buffers

fn input(String message) -> Long {
    out[64];
    Long stdin = fdopen(0, "r");

    puts(message);
    fgets(out, 64, stdin);

    ret out;
}

pub fn main() {
    String res = input("input pls? :pleading:\n");
    printf!("did you say %s? that's so true bestie\n", res);
}

now if i dont fill the whole buffer it adds the newline into the input which is annoying and i dont know how to get rid of it

like the string has a newline

obviously it should be trimmed but no stdlib yet lol

oh c does this too

ok

well in c you can just replace the last character with a null byte

thats not really an option here

at least it compiles

function l $input(l %message_1) {
@start
    %out_3 =l copy $out_2
    %tmp_6 =l call $fdopen(w 0, l $input_5)
    %stdin_4 =l copy %tmp_6
    %tmp_7 =w call $puts(l %message_1)
    %tmp_8 =w call $fgets(l %out_3, w 64, l %stdin_4)
    %r_v8_9 =l copy %out_3
    ret %r_v8_9
}

export function w $main() {
@start
    %tmp_12 =l call $input(l $main_11)
    %res_10 =l copy %tmp_12
    %tmp_14 =w call $printf(l $main_13, ..., l %res_10)
    ret
}

data $out_2 = { b 64 }
data $input_5 = { b "r", b 0 }
data $main_11 = { b "input pls? :pleading:\n", b 0 }
data $main_13 = { b "did you say %s? that's so true bestie\n", b 0 }

[wooden yarrow]

why r u making rust style C

😭

[placid kraken]

lol idk

it wasnt intended to look like C

here we are i guess

[hasty ruin]

That’s what happens when you ask C devs for their input

[torn oriole]

C mfs in chat

[slim bramble]

Better

[placid kraken]

couldnt i technically do this to store strings

%A0 =l alloc4 8      # stack allocate an array A of 2 words
%A1 =l add %A0, 4
storew 43,  %A0      # A[0] <- 43
storew 255, %A1      # A[1] <- 255
%v1 =w loadw  %A0    # %v1 <- A[0] as word
%v2 =w loadsb %A1    # %v2 <- A[1] as signed byte
%v3 =w add %v1, %v2  # %v3 is 42 here

instead of putting them as data sections

this is how C does it too ofc

[placid kraken]

maybe im just picky with the second one lol

[pure acorn]

Is it possible to make tweaks from a jailbroken iPad?

[slim bramble]

yes but it's pain

[placid kraken]

possible and viable are two different words

[pure acorn]

Well luckily I’m a masochist /j

Is there any guide y’all can link me to or should I just look it up?

[placid kraken]

you could manually bit flip the memory on your ram and that would make it “possible”

lmfao

[placid kraken]

probably just look it up yeah

[pure acorn]

What?

[blazing warren]

Walter n 🤣🤣🤣

[hasty ruin]

🤨

[blazing warren]

Well here in Mexico the N is used for someone who was imprisoned and has not yet been proven guilty. example Carlos "N"

[young meteor]

iCraze N

[hasty ruin]

?

[gentle grove]

well typically when you'd expect an "unlimited" input, so you read into the buffer in a loop and go through the text and copy it to a larger heap allocated buffer for the entire input until you get to the end, which you'd know because you'd find the new line

[placid kraken]

yeah i guess that makes sense

i’m honestly kinda tempted to just stack allocate every variable

that way strings can be arrays of chars

[gentle grove]

if you only expect a maximum length input

you'll still have to go through and find the new line and replace it in this case, you can skip steps since you don't care about getting more than the size of the buffer

[placid kraken]

yeah but i can directly access and mutate the last character, if i can get the size of the array ofc

%A0 =l alloc4 8      # stack allocate an array A of 2 words
%A1 =l add %A0, 4
storew 43,  %A0      # A[0] <- 43
storew 255, %A1      # A[1] <- 255
%v1 =w loadw  %A0    # %v1 <- A[0] as word
%v2 =w loadsb %A1    # %v2 <- A[1] as signed byte
%v3 =w add %v1, %v2  # %v3 is 42 here

in this case its still a static array as you need to define the size i think

[gentle grove]

using a loop like I was saying

since the input might be smaller than the buffer

unless there's some other way I don't know of

[placid kraken]

doesn’t need to be a loop i don’t think, just arr[arrlen - 1] == \n ? arr[arrlen - 1] = \0 : do nothing

unless you mean something else

[gentle grove]

but if input is smaller than buffer then newline isn't at the end of array

[placid kraken]

oh i suppose that’s true

why does fgets even have that behavior

[gentle grove]

What do you mean

What else would it do

[placid kraken]

to store a new line instead of a null byte as the last character

[gentle grove]

It's because that's what the input is

you pressed enter

[placid kraken]

oh that makes sense actually yeah

i wonder why normal gets doesn’t do that

[gentle grove]

gets is designed to look for newline or end of file, that's when it ends

[placid kraken]

i seeee

but then i suppose doesn’t fgets do that too then

[gentle grove]

yeah

well it does

but it doesn't delete the newline I guess

[placid kraken]

yeah idk why

[gentle grove]

I think it's because gets is specifically targeted to stdin so they assume you want to get rid of newline given that

since that's what you'd presumably use it for

[placid kraken]

oh also with scanf, can you read infinite characters instead of breaking at a space or is there no way to do that with c format specifiers

[gentle grove]

doesn't it do that by default

THATS how it sounds to me

[placid kraken]

because if you do like

buf[64];
scanf(“%s”, &buf);
``` and you input `abc cba` then buf only gets `abc`

[gentle grove]

Idk then

maybe you're supposed to do a loop

[placid kraken]

String of characters. This will read subsequent characters until a whitespace is found (whitespace characters are considered to be blank, newline and tab).

[native orbit]

"%19[^\n]" would work, stops on new lines

[primal perch]

unsafe

[placid kraken]

im pretty sure it takes in a width

i know it’s unsafe on its own but you can pass that

width
This specifies the maximum number of characters to be read in the current reading operation

arg index 2 aka arg 3

[placid kraken]

but that’s for newlines not spaces isn’t it..?

can i just put [%20] or something

[native orbit]

you want it to not stop when it read a space right?

[placid kraken]

yeah

[native orbit]

this should explain it maybe

// will read 63 bytes, breaking on space
char buf_space[64];
scanf("%63[^ ]", buf_space);

// will read 9 bytes, breaking on newline
char buf_newline[10];
scanf("%9[^\n]", buf);

// will read 23 bytes, breaking on tab
char buf_tab[24];
scanf("%23[^\t]", buf);

[placid kraken]

OH I SEE

SO when you do \n it breaks on only new line

and no longer tab or space?

[placid kraken]

wait so then isn’t scanf safe

if you can read a specific amount of bytes

[native orbit]

correct, so like in the second example it will only stop after 9 bytes or on a new line (if within those 9 bytes), any spaces, tabs, etc will be read as normal

[placid kraken]

yeah that makes sense

[native orbit]

http://sekrit.de/webdocs/c/beginners-guide-away-from-scanf.html

[placid kraken]

from what i read that makes it safe imo

you’re setting a width of up to the size of the buffer - 1 to account for a null byte

so there shouldn’t be a buffer overflow possible

did i not read far enough..?

[grand tide]

if i’m making a tweak that changes something in discord do i want to make the mobile substrate bundle filter (the thing the tweak hooks into) not com.apple.springboard?

[reef trail]

yes

[grand tide]

also if i make a tweak and a repo do i get dev role and also how do i get it to show up with bot on canister

[reef trail]

make a pr to the canister repo

and yes to the dev role

[grand tide]

so what should i make it instead of springboard?

[reef trail]

com.hammerandchisel.discord

[placid kraken]

yeah, discord’s bundle id

https://github.com/enmity-mod/tweak for references if you need any

[grand tide]

so here? https://canister.io/solo

[reef trail]

https://github.com/cnstr/manifests

see https://github.com/cnstr/manifests/pull/91

[grand tide]

oh ok

anyone know a good text editor for coding on mobile?

don’t have access to a pc or mac rn so doing it on mobile

it’s a simple tweak so it’s fine

[reef trail]

filza has a decent one

[grand tide]

alr i’ll use that

[placid kraken]

LMAO I GOT DESTROYED

That's not quite right. It reads characters from stdin up to and
including a newline, then adds a null byte. If the line is longer
than will fit in the buffer, it reads as much as it can then adds
a null byte.

This isn't true. C will stack-allocate the array if you declare it
on the stack (i.e. inside a function without 'static' or 'extern').

If you declare it as at top-level, or inside a function with 'static'
or 'extern', the array will go into .data.

If you are curious how C maps to QBE, you could take a look at the
output generated by cproc.

[grand tide]

should i delete everything in tweak.x and put my code there?

[queen ruin]

No

[grand tide]

why not?

[queen ruin]

Just that won’t necessarily get you dev role

[grand tide]

what will?

[queen ruin]

It might depending the complexity of the tweak, but not necessarily

[grand tide]

ok

[queen ruin]

No set thing

[grand tide]

who decided it anyways? aaron?

[queen ruin]

Mods

It was a mod vote

[grand tide]

ok

[queen ruin]

For me, they approved my dev role based on the stuff I’ve done relatively easily

[grand tide]

also is this correct?

[queen ruin]

The hard part was my past

[grand tide]

ok

[queen ruin]

Look at the stuff written there first but yeah

[placid kraken]

i got my dev role because i have a lot of various projects lmao

idk if i deserve it but whatever

[reef trail]

as long as the tweak isnt something stupid like changing every text to smth it would?

[queen ruin]

Vendetta

[placid kraken]

im not a vendetta dev

[hasty ruin]

[queen ruin]

You make plug-ins?

[queen ruin]

honestly idk, I had been told that it I was somewhat difficult

[placid kraken]

i’m an enmity/unbound dev

[queen ruin]

It wasn’t a piece of cake is what I’m saying

[placid kraken]

yeah i made like 2 lol

[queen ruin]

Yeah that qualifies for dev role I think

[radiant idol]

don't make a tweak just for dev role

make a tweak because you want to, not because of a role

[queen ruin]

Good point

[reef trail]

i doubt they are but yeah i agree

[grand tide]

i’m not making it for the role

just for fun

[radiant idol]

gotcha

well good luck

[grand tide]

i wanna learn some of this stuff you guys always do

[reef trail]

any questions my dms are open :)

[grand tide]

also using your guide nightwind thx

[queen ruin]

Use swift for one
