CoffeeFuck

A BrainFuck interpreter written in CoffeeScript.

Installation

npm install --save coffeefuck

Usage

const coffeefuck = require('coffeefuck');
const result = coffeefuck('++++++++[->+++++<]');
console.log(result.memory);

Return

const {
    output,     // Array of the bytes extracted with "."
    memory,     // Array of the memory
    timeout,    // True if the time exceeded the timeout
    time,       // The time that it took (will be similar to the timeout if set)
} = coffeefuck('++[->+<]');

Options

options.length

Defines the maximal length of memory. (default: 2**32-1)

const result = coffeefuck('+>+>+>+>+>+', { length: 3 });
console.log(result);

options.size

Defines the size of the bytes in the memory. (default: 2**8)

const result = coffeefuck('-', { size: 2**16 });
console.log(result);

options.timeout

Stops running the BrainFuck interpretation after a specific time in milliseconds. (default: Infinity)

const result = coffeefuck('+[]', { timeout: 500 });
console.log(result);

options.inputs

If you know what BrainFuck is, then you know for what this is for. (default: [])

const result = coffeefuck(',[->+<],', { inputs: [69,21] });
console.log(result);

options.async

Returns a promise instead of running synchronously. (default: false)

Note: This makes the interpretation slower.

const result = await coffeefuck('+[>+[>+[+]<+]+[+]<+]', { async: true });
console.log(result);
