# Brainfuck Interpreter in Go
My from scratch implementation of a
[Brainfuck](https://en.wikipedia.org/wiki/Brainfuck) Interpreter written in Golang.
This 300 line project was meant to teach me some Go and maybe a little bit of interpreter crafting.
## Usage
````bash
go run main.go example/helloworld.b
````
This "simple" brainfuck program should print a good old `"Hello World!\n"`
```brainfuck
+++++ +++++ initialize counter (cell #0) to 10
[ set the next four cells to 70, 100, 30 and 10
> +++++ ++ add 7 to cell #1
> +++++ +++++ add 10 to cell #2
> +++ add 3 to cell #3
> + add 1 to cell #4
<<<< - decrement counter (cell #0)
]
> ++ . print 'H' (H = ASC (72))
> + . print 'e' (e = ASC (101))
+++++ ++ . print 'l'
. print 'l'
+++ . print 'o'
> ++ . print ' '
<< +++++ +++++ +++++ . print 'W'
> . print 'o'
+++ . print 'r'
----- - . print 'l'
----- --- . print 'd'
> + . print '!'
> . print '\n'
```
