pars

A simple Rust CLI tool to extract Python function definitions from a .py file.

Vision:

Build a tool that statically parses an entire codebase, giving relevant information like function definitions and heirarchy, the caller-calle relationship etc. A better developed version of the sidebar visible on right-side when you open a file on the github website is maybe a decent description.

Install

cargo install pars

Usage

pars path/to/file.py

Example

pars example.py
