Brainfuck

This is an implementation of a basic brainfuck interpreter written in Elm.

Commands

The brainfuck language consists of the following eight commands:

> increments the data pointer
< decrements the data pointer
+ increments the byte at the data pointer
- decrements the byte at the data pointer
. outputs the byte at the data pointer
, prompts the user for a one byte input
[ jumps to the next ] if the byte at the data pointer is zero
] jumps to the previous [ if the byte at the data pointer is nonzero

Installation

An online demo can be found here: https://www.dragonwasrobot.com/brainfuck/

Ensure you have Elm 0.19.1 installed. I personally recommend using asdf, https://github.com/asdf-vm/asdf, to handle version management of compilers.

With Elm installed, perform the following steps:

Run the command ./build.sh to compile the source, then
open docs/index.html in your favorite browser.
