vorn

vorn is a simple interpreted C-like scripting language I made to learn more about language design and implementation.

Features

• Integers, Floats, Booleans and Strings
• Arithmetic operations
• Logical operators
• Comparison operators
• Variables
• Comments
• Arrays and Object
• If statements
• For and While loops
• Functions
• Built-in functions (See evaluator.go for a complete list)
• Function chaining (See evaluator.go)
• A REPL
• Assignment operators

Planned features

• Ternaries
• Error handling
• Modules/Namespaces/Importing
• Standard library
• Code formatter/Linter

Example

func fib(n) {
    if n <= 1 {
        return n;
    }

    return fib(n - 1) + fib(n - 2);
}

print(fib(10));

This script calculates the 10th number in the Fibonacci sequence, which is 55.

Building

To build vorn, you need to have Go installed. Then, run the following command:

go build

Running

To run vorn, you can either run the executable directly or use the REPL. To run the REPL, run the following command:

./vorn

To run a script, run the following command:

./vorn path/to/script.vorn
