R# - RSX

An interpreted statically typed multi paradigm general purpose programming language designed for cross platform applications.

RSX Icon

Requirements

• Python 3.10 or higher

Getting Started

How to install

Windows (Compiles RSX source files and places them in C:\RSX, also installs the RSX python library)

.\install.bat

Linux (Compiles RSX source files and installs the RSX python library)

./install.sh

Difference between rsxpy and rsx

• rsx only works on Windows
• rsxpy requires python but rsx doesn't

How to [run/build] a RSX program

[rsxpy/rsx] main.rsx [run/build]

How to [run/build] a RSX bytecode

[rsxpy/rsx] main.rsxc [run/build]

How to make a RSX library with python

Using RSX Tools

from rsxpy.tools import *

create_library("library")

@create_function("VOID", {"message": "STRING"})
def log(environment):
    print(environment["args"]["message"], flush = True)

library = pack_library()

Using RSXLib

from rsxpy import rsxlib

rsxlib.begin()

def log(message: str) -> None:
    print(environment["args"]["message"], flush = True)

rsxlib.end()

How to make a RSX library with RSX header files

library.rsxh

include "rsxio" : *;

void log(string message) {
    std::rout(message + std::endl());
}

main.rsx

include "library.rsxh";

int main(string[] args) {
    library::log("Hello, World!");
}

How to add an include folder

[rsxpy/rsx] main.rsx run -Imy-include-folder

Command line arguments

• -I[dir]

Examples

Hello, World!

include "rsxio" : *;

// using namespace std;

int main(string[] args) {
    std::rout("Hello, World!" + std::endl());
    return 0;
}

Builder

include "rsxbuild", "rsxsys", "rsxio" : *;

int main(string[] args) {
    std::rout("file name > ");
    std::build_program(
        std::rin(),
        {std::getdir() + "/include/"},
        true, std::getdir() + "/icon.ico"
    ); return 0;
}

Web Server

include "rsxsocket", "rsxio" : *;

int main(string[] args) {
    auto server = std::socket(std::AF_INET, std::SOCK_STREAM);
    std::bind(server, "localhost", 5656);
    std::listen(server);

    string index = "HTTP/1.1 200 OK\n\n<p>Hello, World!</p>";

    while (true) {
        auto connection = std::accept(server);
        string response = std::recv(connection, 1024);
        std::rout(response + std::endl());
        std::send(connection, index);
        std::close(connection);
    }
    
    return 0;
}

Raylib

include "rsxraylib" : *;

int main(string[] args) {
    InitWindow(1200, 600, "R#");
    // SetTargetFPS(60);

    while (!WindowShouldClose()) {
        BeginDrawing();
        ClearBackground(RAYWHITE);
        DrawFPS(10, 10);
        EndDrawing();
    }

    CloseWindow();
    return 0;
}

3D Projection Using Raylib

include "rsxio", "rsxraylib" : *;

    float[(int) (vertices.length() / 3 * 2)] projected_vertices;
