BFpython

BFpython is an interpreter for the BrainFuck language written in Python.

What is BrainFuck

Brainfuck is an esoteric, Turing-Complete programming language created in 1993 by Urban Müller, notable for its extreme minimalism (only 8 commands !).

It uses an array of 30,000 8-bit integers, and a pointer which can move from cell to cell one at a time. The value of each cell can be incremented or decremented one at a time.

Each Brainfuck programme consists only of the following 8 instructions :

Command	Action
+	increment the value of the current cell by 1
-	decrement the value of the current cell by 1
>	move to next cell
<	move to previous cell
.	print the ascii character of the current cell to stdout
,	get a character from stdin and store it in the current cell
[	if the current cell is 0, jump to the matching ]
]	if the current cell is not 0, jump to the matching [

How to use BFpython

$ git clone https://github.com/Rog3rSm1th/BFpython.git
$ cd BFpython
$ ./bfpython.py -f <path to the brainfuck program>

Flags

Flag	Action
-a/--array	Show the array after the execution.

Use it as a library
