bfpy

bfpy is a Brainfuck Jit Interpreter written in python.

Usage

usage: bfpy [-h] [-o] [-i INPUT] [-f FILE] [-g] [-j] [-r]

brainfuck visualizer

optional arguments:
  -h, --help            show this help message and exit
  -o, --optimize        turn on to enable optimize, note that only if ir was enabled will this option make sense
  -i INPUT, --input INPUT
                        input to the program
  -f FILE, --file FILE  bf program
  -g, --graphic         turn on to enable visualize
  -j, --jit             turn on to enable jit(NOT compatible with graphic), with this on, you CANNOT pass input by argument, please use a pipe
  -r, --ir              turn on to enable ir

On graphic mode

Hold key left to continuously execute step by step, release to stop;Keys up and down to scroll the output.Key space to execute one_step, if you are curious.Press key j, and input some number, and press j again to execute number steps before display current status. While executing, screen won't be freshed so it's much faster than holding key left. If you input nothing between two pressing j, then vm will execute until end. Backspace in j mode is supported.

Note that the graphic part is written with pygame, quick-and-dirty, by me drunk. You cannot expect too much from it.

Requirements

This thing uses peachpy and pygame. pygame can be installed directly via pip, while peachpy needs manual installation(i don't know why but pip just didn't work as expected), the installation guide can be found here.
