@sturmwalzer/brainfuck v0.3.0

brainfuck

A brainfuck interpreter written in JS. Ironic, really. At least it doesn't depend on anything.

Following the inofficial Portable Brainfuck implementation standard as written by Brian Reiter.

Implementation-defined details:

• All cells hold 64 bit floating point integers (largest: 2^53 - 1) which may be negative.
• Characters are represented by their UTF16 code.
• The pointer may not be smaller than zero.
• If input is expected but stdin empty, the program will block and wait for input.

API

const { bf } = require('@sturmwalzer/brainfuck');

// Move value of cell zero (which is read from stdin) to the next cell.
bf(', [ -> +< ] .');

Optionally a function can be passed as the second argument to act as a callback, which will receive the following object as its only argument:

{
    index: number,
    cells: number[],
    pointer: number,
}

bf(', [ -> +< ] .', (meta) => {
    console.log('completed brainfuck execution', meta.cells);
});
