Python has the built in libraries on GitHub, you will have to copy paste them on your own.

All wally and rbxts packages are supported, roblox-pyc has its own registry of python designed packages. Also pip packages are supported, only ones that use 100% python. If it uses C/C++ and you do not have beta mode enabled it will error.

I can agree, it is very cool so I am working on allowing you to use it alongside.

My bad, Iā€™m fixing it rn.

EDIT: I fixed the link

Okay, so the current version is pretty buggy, and slow.

Part of the problem is because I didnā€™t bother to write modularized code, halfway through I did split it to ~12 different python scripts but the python interpreter is so slow. So this time I will be rewriting it inā€¦ C, C++, and a heavily modded version of lua.

With these changes I will also remove it from PyPi (pip) and just have standalone executables available.

I have a whole announcement on the discord server and a step-by-step plan on Github Issues.

This is really cool, I only use roblox luau cause there are no other languages and I miss c++ here. Sad so this only compiles to luau and has no performance gainsā€¦

I havenā€™t used any compiling tools like roblox-ts yet, but I did hear that the compiling of roblox-ts is not always accurate. Can I trust this tool for my game development?

roblox-rs exists that can convert Rust WASM to Luau. obviously it is not going to have good performance, since it is being based on compiling Assembly to a High-level language.

I want to do this but I am quitting roblox development and might pass ownership of this project to someone else after I rewrite some systems.

The compiler is very accurate but the interface is difficult to get started with since it is a pip package and that stopped alot of people from using it, standalone executables are coming soon tho.

Compiling from Lua to Python is not the point of this project, the %s is supposed to be the old code as a reference for you to manually rewrite in Python then compile again using roblox-pyc to Lua.

Heya, any updates on this? Would be awesome to use C++.

It is available but since roblox-pyc split up into multiple compilers it is not apart of roblox-pyc anymore.

Very little examples are provided because this is an experimental but it has a list of which C and C++ features are supported.

Here is a Fibonacci sequence test I did a while ago:

#include "src/rbx.h"

int fibonacci(int n) {
    if (n <= 1) {
        return n;
    } else {
        return fibonacci(n-1) + fibonacci(n-2);
    }
}

int main() {
    int n = 10;
    for (int i = 0; i < n; i++) {
        print((char *)fibonacci(i));
    }
    print("\n");
    return 0;
}

--// Generated by roblox-c v1.0.0 \\--
--Note: This code will not be very clean.

local C = require(game.ReplicatedStorage:WaitForChild("Packages").cruntime)


function fibonacci(n)
    if (n<=1) then
        return n
    else
        return (fibonacci(n-1)+fibonacci(n-2))
    end
end
do
    local n = 10
    local i = 0
    while (i<n) do
        i += 1 
        print(C.cast("char *", fibonacci(i)))
    end
    print("\n")
    return 0
end

Types do not get compiled because typechecking happens by gcc on roblox-c compile time.

Having trouble here. Here is the test.cpp file:

//#include <iostream>
#include "rbx.h"
//using namespace std;

int main() {
    int SECRET_NUMBER = 1;

    if (true) {
        //cout << "Hello, World!" << endl;
        print("Hello, World!");
    }

    switch (SECRET_NUMBER) {
        case 1:
            //cout << "You got it correct with the number 1!" << endl;
            print("You got it correct with the number 1!");
        break;
    
        default:
            //cout << "Oop, secret number isn't 1!" << endl;
            print("Oop, secret number isn't 1!");
        break;
    }

    return 0;
}

When trying to compile, I get this error:

So, I removed the bool literal, now having this:

//#include <iostream>
#include "rbx.h"
//using namespace std;

int main() {
    int SECRET_NUMBER = 1;

    // if (true) {
    //     //cout << "Hello, World!" << endl;
    //     print("Hello, World!");
    // }

    switch (SECRET_NUMBER) {
        case 1:
            //cout << "You got it correct with the number 1!" << endl;
            print("You got it correct with the number 1!");
        break;
    
        default:
            //cout << "Oop, secret number isn't 1!" << endl;
            print("Oop, secret number isn't 1!");
        break;
    }

    return 0;
}

And then I get this:

--// Generated by roblox-c v1.0.0 \\--
--Note: This code will not be very clean.

local C = require(game.ReplicatedStorage:WaitForChild("Packages").cruntime)


do
	local SECRET_NUMBER = 1
	C.switch(SECRET_NUMBER, {
		[1] = function()print("You got it correct with the number 1!")
		end,
		break
		[C.def] = function()print("Oop, secret number isn't 1!")
		end,
		break
	})
	return 0
end

Whichā€¦ doesnā€™t work. In order to get this functionality, I have to remove break.

Thought Iā€™d let ya knowšŸ‘

#35

Thanks for reporting this, Bools arent supported because C++ interprets them as 0 and 1s so I forgot to add it. I will try to improve performance with breaks. Indenting the break the same as the other items should fix it.

This is awesome! I really wanted to use Python when coding in Roblox (this is also a good way if u wanna learn a new Language), im tired of Luau sometimes, but also this gives advantages for people who dont know Lua but want to code on Roblox.

100 likes! Trust me way more is coming, first up the project is now known as RCC roblox-compiler-collection and supports 11 languages now!!

You can read more in the Unexex projects site but more is to come!
