pinit-cli 0.1.2

A smart Python project initializer and dependency manager.

pinit: The Smart Python Project Initializer

pinit is a command-line tool that streamlines the process of starting and managing Python projects. It handles everything from creating a clean project structure and virtual environment to intelligently managing dependencies and running scripts.

It's designed to be a simple, all-in-one replacement for manually running venv, pip install, pip freeze, and managing requirements.txt.

Features

• Interactive Setup: A wizard guides you through creating a new project.
• Automatic Venv: Creates a venv and upgrades pip for you.
• Smart Dependency Management: install and uninstall commands automatically update both a high-level project.json and a complete requirements.txt.
• Intelligent Uninstall: Removing a package also removes its dependencies, unless they are required by another package in your project.
• Script Runner: Run custom commands defined in your project.json with pinit run <script-name>.
• Activated Shell: Jump into an activated virtual environment shell with the pinit shell command.

Installation

You can install pinit directly from PyPI:

pip install pinit-cli

Usage

1. Initialize a New Project

To start a new project, simply run pinit in the directory where you want to create it. The interactive wizard will handle the rest.

pinit

2. Manage Packages

pinit automatically detects and uses the local venv for all package operations.

# Add one or more new packages to the project
pinit install requests flask

# Uninstall a package and its orphaned dependencies
pinit uninstall flask

# Re-install all dependencies from project files
pinit install

3. Run Scripts

You can define custom script shortcuts in the scripts section of your project.json file.

// project.json
{
  ...
  "scripts": {
    "start": "python main.py",
    "test": "pytest"
  },
  ...
}

Run them from your terminal:

# Runs "python main.py" using the venv's interpreter
pinit run start

# Runs "pytest"
pinit run test

4. Use an Activated Shell

For interactive work or debugging, you can launch a new shell session with the virtual environment already activated.

pinit shell

Your terminal prompt will change, indicating you are inside the venv. Type exit to return to your normal shell.
