BangScript

A JavaScript-like (not-JavaScript) scripting language built from scratch for fun and learning purposes. It’s written in Go, with plans to port the interpreter to C for performance, reduced runtime overhead and lower-level control.

Features

• Dynamic Type System
• Functions/Closures
• Automatic Memory Management
• Block c-style comments
• Multi-line string literals

Getting Started

Requirements

• Go 1.21+
• Git

To run the REPL

git clone https://github.com/peterkwesiansah/bangscript.git
cd bangScript/gbs
go run main.go

or a script

git clone https://github.com/peterkwesiansah/bangscript.git
cd bangScript/gbs
go build -o bs
./bs examples/hello.bs

Running a Real Script

You can find this script in examples/counter.bs

fun makeCounter() {
  var count = 0;
  fun inc() {
    count = count + 1;
    print count;
  }
  return inc;
}
var counter = makeCounter();

counter(); // → 1
counter(); // → 2
counter(); // → 3
