Fsk Language (Perfect Edition)

Website docs https://fsk-lang.com

FPM Gestionary package Website https://fpm.kirosb.fr

A high-performance hybrid C++/Rust interpreted programming language.

💎 Beta Édition Features

• Hybrid Core: Critical modules (Crypto, SQL, System, Http) are written in Rust for maximum performance and safety.
• Bytecode VM: Now runs on a register-based Virtual Machine (Rust) instead of slow AST interpretation.
• Production Web Server: Built-in HTTP server powered by Axum & Tokio. Supports WebSockets out of the box.
• Modern Syntax: Arrow functions =>, Async/Await, Destructuring, Optional Chaining ?..

Build

Requirements:

• CMake 3.10+
• C++ Compiler (C++17)
• Rust (Cargo)
• Dependencies: libsqlite3-dev, libssl-dev, libcurl4-openssl-dev, libstdc++, libgcc

To install dependencies on Debian/Ubuntu:

sudo apt install -y git cmake g++ make libsqlite3-dev libssl-dev libcurl4-openssl-dev cargo

mkdir build
cd build
cmake ..
make

Windows Build

Global Installation (System-wide)

Linux

sudo mkdir -p /usr/local/lib/fsk/
sudo cp -r std /usr/local/lib/fsk/
sudo cp build/fsk /usr/local/bin/

Windows (One-Click Installer)

The recommended way for users.

1. Build the project using WINDOWS_BUILD.md.
2. Run package.bat (requires Inno Setup).
3. The installer fsk_setup.exe will be in the Output folder.

Usage

Run a script:

fsk script.fsk

Interactive mode (REPL):

fsk

Production Web Server (std/http)

Fsk includes a high-level web framework inspired by Express.js:

import "http";

const app = new http.Server();

app.get("/", (req, res) => {
    res.send("<h1>Hello from Fsk Perfect Edition!</h1>");
});

app.get("/json", (req, res) => {
    res.json(["Apple", "Banana", "Cherry"]);
});

print "Server running on port 8080";
app.listen(8080);

Standard Library (Rust-Powered)

• Crypto: SHA256, MD5, Base64 (via ring crate).
• SQL: SQLite3 engine (via rusqlite).
• System: Device information (via sysinfo).
• VM: Register-based bytecode execution.
