# Go Brainfuck

This is a simple module to run or debug Brainfuck code.

## Installation

    go get github.com/blixt/go-brainfuck/brainfuck

## Examples

### Hello World

    package main

    

    import (

    	"github.com/blixt/go-brainfuck/brainfuck"

    	"os"

    )

    

    func main() {

    	// Print "Hello" and exit.

    	brainfuck.Run("++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.", "", os.Stdout)

    }

### More advanced & debugging

    package main

    

    import (

    	"fmt"

    	"github.com/blixt/go-brainfuck/brainfuck"

    	"io/ioutil"

    )

    

    func main() {

    	bf := &brainfuck.State{

    		Code:   "++++++++++[>+++++++>++++++++++>+++>+<<<<-]>++.>+.+++++++..+++.",

    		Memory: make([]byte, 100),

    		Output: ioutil.Discard, // Ignore output

    		Debug:  true,

    	}

    

    	// Do 100 iterations.

    	for i := 0; i < 100; i++ {

    		bf.Step()

    	}

    

    	// Print the current memory.

    	fmt.Println(bf.Memory)

    }

## Notes

In case of an EOF read from input, the `,` operator will be a no-op, unlike

some brainfuck implementations that will set the current value to 0 or -1.
