Quick Start

# Create a new package
pkgmngr new my-package
cd my-package

# Generate the package files
pkgmngr create

# Initialize Git and GitHub repositories (requires GITHUB_TOKEN)
pkgmngr init-repo

# Make some changes to your code...

# Take a snapshot of your project
pkgmngr snapshot -m "Initial implementation"

pkgmngr publish

Detailed Usage Guide

Creating a New Package

The new command creates a directory with a configuration file:

# Create a new package directory with config file
pkgmngr new my-package

Output:

✅ Created package directory and config file for 'my-package':
- my-package/pkgmngr.toml

To finish creating your package:
- Change to the project's directory: `cd my-package`
- Review and edit the config file in your favorite editor: e.g. `nano pkgmngr.toml`
- Then run `pkgmngr create` to generate the project files.
...

This creates a directory with a pkgmngr.toml configuration file. You can edit this file to customize package details before generating the actual structure.

# Navigate to the new directory
cd my-package

# Review and edit the config file (pkgmngr.toml)
# Then generate the package files
pkgmngr create

Output:

ℹ️ Creating package structure for 'my-package'...
Created directory: my_package
Created: my_package/__init__.py
Created: my_package/__main__.py
Created directory: tests
Created: tests/test_my_package.py
Created: tests/run_tests.py
Created: setup.py
Created: README.md
Created: MANIFEST.in
Created: pyproject.toml
Created: LICENSE
Created: .gitignore

Package successfully created with the following structure:
./
├── my_package/
│   ├── __init__.py
│   └── __main__.py
├── tests/
│   ├── test_my_package.py
│   └── run_tests.py
├── setup.py
├── README.md
├── MANIFEST.in
├── pyproject.toml
├── LICENSE
└── .gitignore

✅ Package created successfully!

The create command generates a standard Python package structure based on your configuration.

Taking Snapshots

Snapshots create comprehensive Markdown documentation of your codebase:

# Create a snapshot with a comment
pkgmngr snapshot -m "Implemented core features"

# List all available snapshots
pkgmngr snapshot -l

Output:

Available snapshots:
----------------------------------------------------------------------------------------------------
#   Type     Date                Filename                       Comment
----------------------------------------------------------------------------------------------------
1   SNAPSHOT 2025-03-10 15:30:45 snapshot_2025-03-10_15-30-45.md Implemented core features
----------------------------------------------------------------------------------------------------

Snapshots include:

• Directory structure with file type icons
• Navigable table of contents
• All file contents with proper syntax highlighting
• Metadata and comments

Restoring from Snapshots

# Restore from a specific snapshot (by number)
pkgmngr restore 1

# Interactively select files to restore
pkgmngr restore -i

# Restore only Python files
pkgmngr restore -p "*.py"

# Exclude certain files
pkgmngr restore -e "temp_*.py"

# Specify restore mode (safe, overwrite, force)
pkgmngr restore 1 -m safe

Restoration modes:

• safe: Skips existing files
• overwrite: Replaces existing files (default)
• force: Replaces all files, including read-only

Package Lifecycle Management

Renaming Packages

Renaming packages is often a pain in the neck... The rename command allows you to change your package name and automatically updates all references to that name across your package with ease:

# Rename a package (and update all references)
pkgmngr rename old-package-name new-package-name

This command:

• Updates the package directory name (old_name → new_name)
• Updates all occurences of the old name found across directory names, file names, and file contents of your whole project.
• Renames the online GitHub repository too (if any).

Output:

ℹ️ Updated config file with new package name: new-package-name
ℹ️ Renamed package directory: old_package_name → new_package_name
ℹ️ Updated references in README.md
...
✅ Project successfully renamed from 'old-package-name' to 'new-package-name'

Example usage:

# Before: my-package (directory: my_package)
pkgmngr rename my-package awesome-package
# After: awesome-package (directory: awesome_package)

Note that this command must be run from the package root directory (where the pkgmngr.toml file is located).

GitHub Integration

GitHub Personal Access Token

For GitHub integration, you'll need a GitHub Personal Access Token with the repo scope:

1. Go to GitHub → Settings → Developer settings → Personal access tokens → Tokens (classic)
2. Generate a new token with the repo scope
3. Set it as the GITHUB_TOKEN environment variable:

   export GITHUB_TOKEN=your_token_here
   

Usage

Initialize Git and create a GitHub repository:

# Initialize Git and GitHub repositories
pkgmngr init-repo

Output:

ℹ️ Detected GitHub repository: yourusername/my-package
ℹ️ Initialized empty Git repository
ℹ️ Created initial commit
ℹ️ Creating GitHub repository: yourusername/my-package...
✅ Created GitHub repository: yourusername/my-package
ℹ️ Pushing code to GitHub...
✅ Pushed code to GitHub: https://github.com/yourusername/my-package.git
✅ Repository initialization completed successfully!

Then you can push the changes you make to your code using the push command

# Push changes to GitHub (with interactive commit message)
pkgmngr push

PyPI Management

PyPI/TestPyPI Authentication

Publishing to PyPI or TestPyPI requires properly configured authentication for twine. Before using the publish command, ensure you have:

1. A PyPI account (and TestPyPI account if using --test)
2. Configured twine authentication using one of these methods:
   • A .pypirc file in your home directory:

     [distutils]
     index-servers=
         pypi
         testpypi
     
     [pypi]
     username = your_username
     password = your_password
     
     [testpypi]
     repository = https://test.pypi.org/legacy/
     username = your_testpypi_username
     password = your_testpypi_password
     

   • Environment variables: TWINE_USERNAME and TWINE_PASSWORD
   • Interactive prompt: If credentials aren't found, twine will prompt for them

For security, using API tokens instead of passwords is recommended:

1. Generate tokens at https://pypi.org/manage/account/#api-tokens (or https://test.pypi.org/manage/account/#api-tokens)
2. Use the token as your password with username __token__

The pkgmngr publish command relies on these authentication methods for successful uploads.

Usage

# Publish to TestPyPI
pkgmngr publish --test

# Publish to PyPI with automatic patch version increment
pkgmngr publish

The publish command allows automatic version increments following semantic versioning principles:

# Publish to PyPI with automatic patch version increment (e.g., 0.1.0 → 0.1.1)
pkgmngr publish

# Publish to PyPI with a minor version increment (e.g., 0.1.1 → 0.2.0)
pkgmngr publish --bump minor

# Publish to PyPI with a major version increment (e.g., 0.2.0 → 1.0.0)
pkgmngr publish --bump major

# Publish to TestPyPI with version increment
pkgmngr publish --test --bump patch

Version information is tracked in your pkgmngr.toml configuration file and automatically updated in:

• pkgmngr.toml (master record)
• yourpackage/__init__.py (__version__ attribute)
• setup.py (package version)

This ensures your package version is consistently maintained across all relevant files when publishing.

Configuration

The pkgmngr.toml file contains configuration settings for your package:

package_name = "my-package"
version = "0.1.0"
author = "Your Name"
year = "2025"
description = "A Python package named my-package"

[github]
username = "your-username"
private = false

[python]
requires = ">=3.6"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",
]

[dependencies]
requires = []
dev_requires = [
    "pytest",
    "pytest-cov",
    "flake8",
    "black",
]

Snapshot Features

Beautiful Directory Tree

Snapshots include a visually enhanced directory tree with file type icons and proper hierarchy:

📦 my_project
├─ 📂 src
│  ├─ 🐍 __init__.py
│  ├─ 🐍 main.py
│  └─ 🐍 utils.py
├─ 📂 tests
│  ├─ 🐍 test_main.py
│  └─ 🐍 test_utils.py
├─ 📝 README.md
└─ 📋 requirements.txt

Navigable Table of Contents

Each snapshot includes a clickable table of contents that links directly to file sections for easy navigation.

Syntax Highlighting

Code sections are properly syntax-highlighted based on file extensions, making your snapshots readable and beautiful.

Advanced Usage

Custom Snapshot Paths

# Specify a different start path and output folder
pkgmngr snapshot /path/to/project -o custom_snapshots

Gitignore Integration

Snapshots respect your .gitignore patterns, but also support special #pkgmngr prefixed patterns that only apply to snapshots:

# Regular .gitignore pattern (ignored by Git and snapshots)
__pycache__/

# Snapshot-specific pattern (ignored by snapshots only)
#pkgmngr secrets.json

Automatic Backups

When restoring, a backup snapshot is automatically created:

# Restore without creating a backup
pkgmngr restore 1 --no-backup

# Specify a custom backup location
pkgmngr restore 1 -b /path/to/backup.md

Troubleshooting

Common Issues

1. 'pkgmngr' command not found

   • Ensure the installation directory is in your PATH
   • Try installing with pip install --user pkgmngr

2. GitHub authentication errors

   • Check that your GITHUB_TOKEN environment variable is set correctly
   • Ensure your token has the 'repo' scope

3. Snapshot restore fails

   • Check if you have write permissions to all affected files
   • Try using the -m force option for stubborn files
