NothScript

NothScript programming language. It is built using TypeScript and JavaScript and requires Node.js version 18 or higher.

Installation

To use NothScript, make sure you have Node.js installed.

$ npm i -g pebrianz/nothscript#dist

Then, you can run your code using the provided interpreter.

$ ns index.ns

Syntax Overview

Variable Declaration

x:num = 10;

In NothScript, you can declare variables using the : symbol, followed by the type of the variable (num, str, bool, or none).).

Variable Assignment

x = 30;

You can assign values to variables without specifying the type.

Function Definition

fn add a:num b:num ::num {
   rn a + b;
}

Define functions using the fn keyword, followed by the function name, parameters with their types, and the return type specified after ::.

Function Call

add(10, 20);

Call functions by using their names and passing arguments inside parentheses.

Arrow Function

fn add a:num b:num ::num => a + b;

Arrow functions provide a more concise way to define simple functions.

Overload Function

fn add a:num b:num ::num => a + b;
fn add a:str b:str ::str {
   rn "{a} {b}";
}

If-Else Statement

if 10 > 5 {
   print "hello";
} else {
   print "world";
}

Make decisions using if and else statements with conditions enclosed in curly braces.

While Loop

while x < 100 {
   print "hello world";
   x = x + 1;
}

Execute a block of code repeatedly with a while loop.

Input and Output

print "hello world";
x:num = number(input("your age: "));
print "your age is {x}";

Use print to display output and input to receive user input. Note that number is used to convert the input to a numeric value.

Example

fn factorial n:num ::num {
   if n <= 1 {
      rn 1;
   } else {
      rn n * factorial(n - 1);
   }
}

x:num = 5;
result:num = factorial(x);
print "Factorial of {x} is {result}.";

This example demonstrates how to use recursion to calculate the factorial of a number in YourLanguageName.
