🔢

Statically Typed

Every variable has an explicit type — int, dec, txt, bool, array, or struct. No runtime surprises.

⚡

Fast & Lightweight

Zero external runtime dependencies. Lexer → Parser → AST → Evaluator pipeline starts instantly.

🏗️

Structs & Functions

First-class user-defined structs with field access and mutation. Functions support recursion and struct-typed parameters.

📥

Unified I/O

read() auto-detects int, dec, or txt from user input. Type conversion via int(), dec(), txt() casts.

🔁

Rich Control Flow

if/else, while loops, for-range loops, for-in array loops, break, continue, and early return.

🧮

Symbolic Math

Built-in math engine for solving equations, simplifying expressions, and numeric evaluation. Constants like π, e, τ.

A taste of MLang

mlang

struct Point {
    int x
    int y
}

int distance_sq(Point a, Point b) {
    int dx = a.x - b.x;
    int dy = a.y - b.y;
    return dx * dx + dy * dy;
}

main() {
    Point p1 = Point { x = 0, y = 0 };
    Point p2 = Point { x = 3, y = 4 };
    print(distance_sq(p1, p2));   # 25

    txt name = read("Your name: ");
    print("Hello, " + name);
}
