# BFRS

[![Build Status](https://travis-ci.org/deciduously/bfrs.svg?branch=master)](https://travis-ci.org/deciduously/bfrs)

Quick 'n dirty [BrainFuck](https://en.wikipedia.org/wiki/Brainfuck) interpereter in Rust.

## Dependencies

Rust 1.25.0 or higher (I jumped on those nested import groups).  Or download the 64-bit Linux binary from [releases](https://github.com/deciduously/bfrs/releases).

## Usage

`bfrs` accepts a brainfuck file as its first argument, and optionally a second argument of either `-d` or `--debug` to dump machine state after each instruction, which is obnoxious. For example: `bfrs resource/benchmark.b -d`.

## Development

Use [cargo](https://doc.rust-lang.org/stable/cargo) run, test, install, --release, etc.

## Performance

Middling.

On my machine (AMD A10-5750M) it runs `benchmark.b` in 6.66 seconds and [`mandel.b`](https://github.com/kostya/benchmarks/blob/master/brainfuck2/mandel.b) in 95.02 seconds.

First stab at it was even worse, 13.21 and 221.16 respectively, so, you know, gainz.
