GoScript

GoScript is a lightweight scripting language implemented in Go. It provides a simple, expressive syntax for common scripting tasks and serves as an excellent platform for learning language design and building domain-specific languages.

Features

• Interpreted Scripting: Write and execute scripts without a separate compilation step.
• Simple Syntax: Clean and intuitive syntax for arithmetic, logic, conditionals, loops, functions, and more.
• Modular Design: Easily extend or integrate new features thanks to the well-organized code structure.
• Cross-Platform: Built in Go, GoScript can run on any platform that supports Go.

Syntax

Hello World:

print("Hey World!")

Fibonacci:

fn f(n) {
    if n <= 1 { 1 }
    n * f(n-1)
}

println(f(5))

Getting Started

Prerequisites

• Go Tested on 1.22.4

Installation

Clone the repository:

git clone https://github.com/BaseMax/GoScript.git
cd GoScript

Build the project:

go build -o goscript
or
go build -o goscript.exe

Alternatively, you can run it directly with:

go run goscript.go

Running a Script

After building the executable, you can run a GoScript file by providing its path as an argument:

./goscript.exe path/to/your/script.gos

For example, to run one of the provided examples:

./goscript.exe examples/hello.gos
