# 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.
