Hi @haeter525
First of all, nice work on the Rizin integration!
Thanks for the contribution you made. It is a great milestone for us.

However, since our project wants to be more contributor friendly,
I suggest we edit documents for the functions in the codebase.
The documents give a short description of the function and how to use it.
And I think it also will help us to maintain the codebase.

For example:

def color(text, color_code): """Colorize text.  @param text: text.  @param color_code: color.  @return: colorized text.  """ if sys.platform == "win32" and os.getenv("TERM") != "xterm": return text return "\x1b[%dm%s\x1b[0m" % (color_code, text)

Thank @pulorsok for the nice suggestion. I've updated the docstring in #335.
Once we merge that PR, I will rebase the commits to ensure all methods here are well-documented.
