harakiri lib

Library for parsing, type checking and compiling a simple programming language named harakiri. It's implemented without LLVM or GCC backend.

Supported architectures

• Aarch64

Syntax

All supported constructions are used in the code below:

def fib(n) {
    if n <= 2 {
        return 1
    }
    return fib(n-1) + fib(n-2)
}

def print_interval(from, to) {
    while from < to {
        echo(from)
        from = from + 1
    }
}

def main() {
    echo("Enter mode: 0 - interval printer, 1 - fibonacci calculator")
    a = -1
    while 1 {
        a = input()
        if a != 0 && a != 1 {
            echo("Mode must be equal to 0 or 1")
        } else {
            break
        }
    }
    
    if a == 0 {
        echo("enter start value")
        a = input()
        echo("enter end value")
        b = input()
        print_interval(a, b)
    } else {
        echo("enter n to get n-th fibonacci number")
        a = input()
        echo(a, "-th fibonacci number is: ", fib(a))
    }
}
