docify

A script to add docstrings to Python type stubs using reflection

Features

• Uses LibCST to parse and modify the stub file
• Dynamically imports the actual module to get the runtime docstring
• Handles most sys.version and sys.platform conditional blocks, will only add docstrings to the correct branch
• Able to modify files in-place with -i or --in-place
• Won't overwrite existing docstrings
• With -b or --builtins-only, will only add docstrings for modules found in sys.builtin_module_names (stdlib modules written in C). Useful for language servers that would otherwise not be able to find docstrings due to there being no source file.

Requirements

• Python 3.8+
• LibCST, and tqdm for a progress bar if running without -q
