pystructure

A tiny tool to help reading source code with showing structure of python source code

Why

I use PyCharm as my python IDE, and sometimes I can use structure navigation view to check code structure easily, like below:

structure

structure

It is useful when you read some open source codes, and for me, I like to write memo for code structure down in my note, but you can not copy the structure information to text from PyCharm, so I create this tool to help me easily to output text version of structure of python code.

Installation

pip install pystructure

Usage

> pystructure

Usage:
    pystructure.py SRC_PATH [-o FILE | --output=FILE]

> pystructure pystructure.py

Implementation

  • ast - Build-in python library, to do static analytic for the source code
  • docopt - A great tool to help to create beautiful CLI for you

Contribution

  1. Fork the repository on GitHub.
  2. Make a branch off of master and commit your changes to it.
  3. Run the tests with tox
  • Either use tox to build against all supported Python versions (if you have them installed) or use tox -e py{version} to test against a specific version, e.g., tox -e py27 or tox -e py33.
  1. Submit a Pull Request to the master branch on GitHub.

If you’d like to have a development environment for pystructure, you should create a virtualenv and then do pip install -e . from within the directory.
