Linux is finally fully running on Scratch!

Executec

presumably it's just a list of individual bytes?? writing a converter in cpp rn

Executec

thanks to the amazing people in the C++ community I found a way to convert it back to bytes:

#include <cstdio>
#include <filesystem>
#include <iostream>
#include <fstream>

int main() {
    std::ifstream input_stream("input.txt");
    std::ofstream output_stream("output.txt");
    
    for (;;) {
        int byte;
        input_stream >> byte;
        if (input_stream.eof())
            break;
        output_stream << (char)byte;
    }
}

unless you ran it on a supercomputer, but who runs Scratch on a supercomputer? Besides, most of those already run UNIX-like systems
Honestly, I think it's a cool project and a cool idea. Eventually, though, you're going to run into the project json limit or it's going to lag like hell even on Turbowarp.
sorry to say,but everyone on scratch uses windows,not linux or anything like that. i bet supercomputers can't run scratch unless their browsers support webgl,which is unlikely
None of that is true lol

Supercomputers generally don't have web browsers at all but there isn't anything preventing you from installing one and running scratch on it, aside from the lack of display outputs

Sorry I am like 6 months late, but it may be possible to run System 4 (really old Mac OS) on Scratch using a motorola 68000 emulator.

Executec

the default ROM for the emulator this was based on doesn't seem to work on here…. no output, just a blinking cursor. my conversion script converts back-and-forth just fine, and the ROM used in the scratch project works fine in the native version of the emulator. i don't know what I could do next to try and debug honestly

Executec

converter code in full if anyone finds it useful, compiles fine on the latest G++ compiler:

#include <fstream>
#include <iostream>

void convert_to_scratch(std::string input, std::string output) {
    std::ifstream input_stream("input.txt");
    std::ofstream output_stream("output.txt");
    for (;;) {
        char byte;
            input_stream >> byte;
            if (input_stream.eof())
                break;
                output_stream << std::to_string(int(byte) + 128) << "\n";
            }
}

void convert_from_scratch(std::string input, std::string output) {
    std::ifstream input_stream("risc.txt");
    std::ofstream output_stream("output.txt");

    for (;;) {
        int byte;
        input_stream >> byte;
        if (input_stream.eof())
            break;
        output_stream << (char)byte;
    }
}

int main(int argc, char* argv[]) {
    std::cout << "Linux on Scratch ROM Converter - easter man 2024\n";
    if (argc == 3) {
        std::cout << "t - to Scratch\nf - from Scratch\nAnswer:";
        std::string conversion_mode;
        std::cin >> conversion_mode;
        if (conversion_mode == "t") {
            convert_to_scratch(argv[1], argv[2]);
        } else if (conversion_mode == "f") {
            convert_from_scratch(argv[1], argv[2]);
        }
        std::cout << "Finished!";
    } else {
        std::cout << "Invalid argument\nCorrect format:\n./converter input.txt output.txt\n";
    }
}

How?! I thought Linux on Scratch was imposssible due to scratch´s inability to make operating systems that arent simulated/fake
The limitation is that it takes a lot of time and effort to do so, there isn’t a technical limitation

You´re quite wrong,just look at Scratch Wiki´s statement.

Scratch does not have the capability to create a true operating system.

no

Very late response, but no.

The last time I used Scratch on Windows for more than 5 minutes was 2021.

I only use Scratch for any period of time on Linux, ChromeOS (Linux-based), and iPadOS (very far removed from UNIX, but still bears some resemblance).

You're wrong when i mean everyone uses windows on scratch.

Many people here on scratch uses Windows.

I'm willing to bet that you're even wrong about that- many Scratchers use Scratch in schools, and schools, for the most part, don't buy Windows laptops (too expensive, for the most part). They buy Chromebooks and iPads.

The world does not run on Windows.

Anyone can buy a cheap low end windows laptop to use scratch,and Scratch isn't hardware intensive.

many people here use linux, especially in the ATs, and not everybody can just go buy a laptop.
most “cheap” laptops nowadays run chromeOS, which is basically a locked down linux

Well,if that's true,i'm the exception..

I use an Windows 10 PC with old but still modern components from around early 2010s (at the latest) with a Celeron G530 cpu, Intel HD Graphics (Sandy Bridge) and Realtek PCIe FE Family Controller (RTL8136).
