docstring-generator-ext 1.0.2

Generate Docstrings with type-hint information.

Docstring Generator Extension

docstring_generator_ext is a high-performance Python extension written in C++ (using pybind11) designed to automatically generate and inject docstrings into Python source files. It leverages Python's ast module to extract type-hint information and function signatures to create well-formatted docstrings in various styles.

Features

• Automatic Docstring Injection: Parses Python files and inserts docstrings for functions and methods.
• Type-Hint Awareness: Extracts type information from annotations and default values.
• Multiple Styles: Supports popular docstring formats:
  • reST (reStructuredText)
  • Google style
  • NumPy style
• High Performance: Core logic implemented in C++ for fast processing.
• Preserves Existing Content: Can update existing docstrings while trying to preserve manually added descriptions (using a special $ marker convention).

Installation

Prerequisites

• Python 3.13 or higher
• A C++ compiler with C++20 support (e.g., GCC, Clang, or MSVC)
• pybind11

Building from Source

1. Clone the repository:

   git clone https://github.com/FelixTheC/docstring_generator_ext.git
   cd docstring_generator_ext
   

2. Install the build package:

   pip install build
   

3. Build the package:

   python -m build
   

4. Install the built wheel:

   pip install dist/docstring_generator_ext-*.whl
   

Usage

After installation, you can use the extension in your Python scripts:

import docstring_generator_ext

# Path to the Python file you want to process
file_path = "path/to/your_script.py"

# Choose a style: GOOGLE, NUMPY, or reST
style = docstring_generator_ext.DocstringFormatStyle.GOOGLE

# Generate and inject docstrings
docstring_generator_ext.parse_file(file_path, style)

Docstring Styles

The extension provides an enum DocstringFormatStyle to choose the desired output:

• docstring_generator_ext.DocstringFormatStyle.reST
• docstring_generator_ext.DocstringFormatStyle.GOOGLE
• docstring_generator_ext.DocstringFormatStyle.NUMPY
