pyinitgen 3.0.2

Auto-generate missing __init__.py files to fix Python import issues and ensure proper module discovery.

---

pyinitgen

Automated init.py generator for Python packages Ensures every directory in your project is a proper Python package — no more mysterious ModuleNotFoundError surprises.

Perfect for:

Large refactors

Monorepos / multi-package architectures

Auto-generated project structures

Migration from namespace-less directories

CI environments ensuring package integrity

🚀 Features

Feature	Description
📂 Recursive Scan	Walks the directory tree intelligently to find all Python modules.
🛠️ Auto-creates __init__.py	Creates __init__.py files only where they are missing.
🧠 Smart Exclusions	Ignores common system and runtime directories by default.
📝 Customized Ignores	Supports a .pyinitgenignore file to add your own exclusion rules.
✍️ Custom Content	Lets you write custom content to newly created __init__.py files.
👀 Dry-Run Mode	Preview which __init__.py files will be created without writing them.
🎯 Project-safe	Avoids touching non-Python folders and respects your project structure.
✨ Emoji Status	Provides an optional, fancy terminal UX with emoji status indicators.
🔒 Zero Destructive Actions	Never overwrites existing files or content.

📦 Installation

pip install pyinitgen

⚙️ Configuration & Advanced Usage

CLI Arguments

Argument	Short	Description	Default
--base-dir <path>		Base directory to scan.	.
--dry-run		Preview changes without writing to disk.	false
--quiet	-q	Suppress all non-error output.	false
--verbose	-v	Show all scanned directories.	false
--no-emoji		Disable emoji in the final output.	false
--init-content "..."		Custom content to write to new __init__.py files.	""
--version		Show the program's version number and exit.

Customizing Exclusions with .pyinitgenignore

To exclude specific directories from being scanned, create a .pyinitgenignore file in your project's root directory. Each line in this file is treated as a pattern to be excluded.

Note: This feature is ideal for excluding auto-generated folders, data directories, or any other project-specific directories that should not be treated as Python packages.

Example .pyinitgenignore:

# .pyinitgenignore
# Exclude the entire 'assets' directory
assets

# Exclude any directories named 'legacy'
legacy

📝 Example Output

Scanning: src/utils Created src/utils/init.py ✅ Operation complete. Scanned 43 dirs, created 8 new init.py files.

🧩 Why this tool?

Problem Solution

Large Python codebases without -inits Auto insert all required files ModuleNotFoundError during import Ensures folders become packages Hand-creating 50+ init.py files One command 🤖 Accidental file writes? Only creates missing files

---

⚙️ CLI Help

pyinitgen --help

---

🛡️ Safe by Design

Never touches existing files

Ignores system & irrelevant dirs by default

Supports dry-run to preview

---

💡 Tip

Use in CI to guarantee package consistency:

pyinitgen --dry-run

---

🏗️ Architecture

The project is structured as a standard Python CLI application:

src/
└── pyinitgen/
    ├── __init__.py
    ├── banner.py   # Renders the ASCII logo
    └── cli.py      # Core logic and CLI argument parsing

The core logic resides in cli.py, which performs the directory scan and __init__.py file creation. The banner.py module is a purely cosmetic addition to improve the user experience.

---

🗺️ Roadmap

• Add support for customizing the default exclusion list via a configuration file.
• Implement a --watch mode to automatically create __init__.py files as new directories are created.
• Add a --check flag that will exit with a non-zero status code if any __init__.py files are missing, but will not create them.
