A Brainfuck interpreter, written in Python.
Brainfuck is an esoteric programming language with an extremely minimalistic syntax. It is considered Turing complete. You can find a deeper explanation along with several examples on Wikipedia.
Important note on implementation: This implementation supports arbitrary high cell values and a dynamically growing memory tape. Therefore there's no wrapping for cells or the tape!
python ./brainfuck.py [-h] [-c CODE|-f FILE] [-i INPUT] [--debug CHAR]
-hDisplay a help message and exits.
-cPass your code as a command-line argument.
-fThe programm takes the code from an external file with text-based format.
-iDefine the input for your program.
--debugIf enabled, a '#' in your brainfuck code will pause to running programm and display useful debugging information. You can change the token by additionaly providing a single character.
Python has to be installed in order to use it. To do so (Ubuntu):
sudo apt-get install python
Creating a useful alias:
echo "alias brainfuck='python ~/replace/with/your/directory/brainfuck.py '" >> ~/.bash_aliases
With this one you can use:
brainfuck [-h] [-c CODE|-f FILE] [-i INPUT] [--debug CHAR]
Feel free to modify this code, report bugs, give advices to enhance it or ask questions about the source code (obviously I'm not that good at commenting my code).
