brainfuck-node

A lightweight brainfuck interpreter that actually functions as expected.

Why?

There are an abundance of brainfuck libraries out there, but none of them worked for me.

What makes this one different?

This library promises to

1. Be fast. We can execute 1 million steps in less than 200ms.
2. Interpret correctly. Our [ and ] operators function as they're supposed to.
3. Take input statically instead of with stdin. This is useful for programatic usage, rather than in a CLI.
4. Be lightweight. Instead of using a recursive hell with an infinitely large stack depth, we do everything in a simple loop.
5. Have no external dependencies. Bloat is bloat.

Usage

Usage is simple.

const Brainfuck = require('brainfuck-node');
const brainfuck = new Brainfuck();

let result = brainfuck.execute(',[>,]<[<]>[.>]', 'Hello World');
console.log(result);

It's that easy.

Configuration

The Brainfuck constructor takes an option argument with the following properties:

• options.maxSteps - The maximum number of steps to execute (defaults to 1000000). Set to -1 to disable.
