pyumlify 0.1.0

Generate PlantUML diagrams from Python code automatically.

PyUMLify

Automatically generate UML class and package diagrams from your Python project using PlantUML.

PyUMLify is a lightweight Python tool that scans your project's source code and automatically generates PlantUML class and package diagrams. It's designed to improve documentation and architecture visibility in any Python-based project — whether it's a microservice, CLI, library, or monolith.

---

✨ What is it?

PyUMLify scans your Python project to identify classes, methods, and their relationships, and then generates .puml files ready to be rendered with PlantUML.

🚀 Installation

pip install pyumlify

Or, if you're developing or testing locally:

git clone https://github.com/guipatriota/pyumlify.git
cd pyumlify
pip install -e .

🛠️ Usage

pyumlify --root . --output plantuml_output

Optional flags:

• --requirements: path to your requirements.txt (default is requirements.txt)
• --include: extra external libraries to ignore (e.g. --include pandas numpy)
• --clear: remove the output directory before generating
• --force: overwrite .puml files even if they already exist

Example:

pyumlify --root src/ --output uml/ --requirements requirements.txt --include pandas numpy --force

📦 Output

• One .puml file per package/module
• A packages.puml showing the relationships between modules

You can visualize the diagrams using:

• PlantUML
• VSCode Plugin
• Any tool that supports .puml rendering

📌 Features

• 📂 Supports large Python projects with nested folders
• 📚 Detects class dependencies and method return types
• 🧠 Ignores standard libraries and known third-party packages
• 💡 Highlighted themes and class formatting included

🧪 Testing

Run all tests using:
