AI Documentation Generator 🤖📚

Automatically generate comprehensive documentation for your Python projects using OpenAI's GPT models. This tool analyzes your codebase and creates detailed, well-structured documentation that helps developers understand and use your code effectively.

✨ Features

• 🔍 Intelligent Code Analysis: Uses AST parsing to understand your code structure
• 📝 Comprehensive Documentation: Generates detailed docs for modules, classes, functions, and more
• 🚀 Incremental Updates: Only regenerates docs for files that have changed
• 🔧 Git Integration: Tracks changes through git history
• 💰 Cost-Effective: Minimal API usage through smart caching and incremental updates
• 🎨 Beautiful Output: Generates well-structured Markdown documentation
• ⚙️ Highly Configurable: Customize what gets documented and how
• 🖥️ CLI & API: Use as a command-line tool or integrate into your Python projects

📦 Installation

pip install ai-doc-generator

Or install from source:

git clone https://github.com/haseebrj17/ai-doc-generator.git
cd ai-doc-generator
pip install -e .

🚀 Quick Start

1. Set your OpenAI API key:

export OPENAI_API_KEY="your-api-key-here"

2. Generate documentation for your project:

ai-doc-gen /path/to/your/project

That's it! Your documentation will be generated in docs/generated/.

📖 Usage

Command Line Interface

# Generate docs for current directory
ai-doc-gen

# Generate docs for specific path
ai-doc-gen /path/to/project

# Force full regeneration (ignore cache)
ai-doc-gen --full

# Use a specific model
ai-doc-gen --model gpt-4o-mini

# Custom output directory
ai-doc-gen --output docs/api

# Include test files
ai-doc-gen --include-tests

# Dry run to see what would be documented
ai-doc-gen --dry-run

Python API

from ai_doc_generator import Config, DocumentationGenerator

# Create configuration
config = Config(
    project_root="./my_project",
    output_dir="./docs",
    include_tests=False,
    model="gpt-4o"
)

# Generate documentation
generator = DocumentationGenerator(config)
generator.generate_documentation()

⚙️ Configuration

Create a ai-doc-config.json file in your project root:

{
  "model": "gpt-4o",
  "output_dir": "docs/generated",
  "include_patterns": ["*.py"],
  "exclude_dirs": ["tests", "__pycache__", ".venv"],
  "exclude_files": ["setup.py"],
  "max_file_size": 100000,
  "include_tests": false
}

💸 Cost Estimation

For a typical Python project:

• Small project (10k lines): ~$2-3
• Medium project (50k lines): ~$8-12
• Large project (100k lines): ~$15-25

After initial generation, incremental updates cost 90% less!

📁 Output Structure

docs/generated/
├── README.md                 # Main documentation index
├── project-overview.md       # High-level project analysis
├── api-reference.md         # Complete API reference
├── modules/                 # Module-specific documentation
│   ├── core/
│   ├── utils/
│   └── ...
└── documentation.json       # Raw documentation data

🛠️ Advanced Features

Incremental Documentation

Only regenerate documentation for files that have changed:

# First run - documents everything
ai-doc-gen

# Subsequent runs - only changed files
ai-doc-gen

Custom Prompts

Customize the documentation style:

config = Config(
    system_prompt="Generate concise API documentation focusing on usage examples..."
)

Multiple Models

Use different models for different purposes:

• gpt-4o: Best quality, detailed documentation
• gpt-4o-mini: Faster and cheaper, good for most projects
• gpt-4-turbo-preview: Balance of quality and cost

Setting up GitHub Pages

1. Go to Settings → Pages in your GitHub repository
2. Under "Build and deployment", select "Deploy from a branch"
3. Choose gh-pages branch and / (root) folder
4. Click Save

🚀 Publishing to PyPI

This project has automated publishing workflows:

Automatic Publishing

When you push changes to main with an updated version in pyproject.toml, the package will automatically be published to PyPI if all tests pass.

Manual Publishing

1. Create a new tag: git tag v1.0.1 && git push origin v1.0.1
2. The workflow will automatically publish to PyPI

Setting up PyPI Tokens

1. Create an account on PyPI
2. Generate an API token from your account settings
3. Add the token as PYPI_API_TOKEN in your repository secrets (Settings → Secrets → Actions)
4. Optionally, add TEST_PYPI_API_TOKEN for test releases
