Installation

First install the following requirements:

• Python 3
• the dependencies listed in requirements.txt (pip install -r requirements or pip3 install -r requirements depending on your OS)

Run the script astvisualizer.py. It accepts the input on stdin. Alternatively you might specify a file name as first parameter.

Usage

By default astvisualizer.py reads the Python code from stdin.

If you only want to visualize a short snippet you can also pass it directly on the command line, f.e. astvisualizer.py "print(3/2)".

If you want to visualize an existing Python source code file, pass the file name using the -f switch, f.e. astvisualizer.py -f test.py.
