Quick Start

Create a New Project

ppmm new my-project
cd my-project
ppmm start

Initialize in Existing Directory

cd existing-project
ppmm init
ppmm add numpy pandas
ppmm start

Add Packages

ppmm add requests flask
ppmm add beautifulsoup4==4.9.0

Run Project

ppmm start

Run Custom Scripts

ppmm run test
ppmm run build

Installation

Using Cargo (Recommended)

Install directly from crates.io:

cargo install ppmm

Using Homebrew (macOS/Linux)

# Coming soon - waiting for tap creation
brew tap Sumangal44/ppmm
brew install ppmm

Using Scoop (Windows)

# Coming soon - waiting for bucket submission
scoop bucket add ppmm https://github.com/Sumangal44/ppmm
scoop install ppmm

From Binary Releases

Download pre-built binaries from GitHub Releases:

Linux/macOS:

# Download and extract
curl -L https://github.com/Sumangal44/ppmm/releases/latest/download/ppmm-linux-x64.tar.gz | tar xz
sudo mv ppmm /usr/local/bin/
ppmm --version

Windows:

# Download from releases page and add to PATH
# Or use the installer executable

Script install (Linux/macOS)

From the repository root run:

git clone https://github.com/Sumangal44/ppmm.git
cd ppmm
bash install.sh

This uses install.sh to check prerequisites, build, and place ppmm in /usr/local/bin (prompts for sudo if needed).

Quick one-liner (Linux/macOS)

bash <(curl -s https://raw.githubusercontent.com/Sumangal44/ppmm/master/quick-install.sh)

Or run locally: bash quick-install.sh after cloning. Script lives at quick-install.sh.

Manual install (Linux/macOS/Windows)

Requirements: Rust 1.60+, Python 3.7+, Git.

git clone https://github.com/Sumangal44/ppmm.git
cd ppmm
cargo build --release

# Linux/macOS
sudo cp target/release/ppmm /usr/local/bin/

# Windows (PowerShell/CMD)
copy target\release\ppmm.exe C:\\Windows\\System32\\   # or add target\release to PATH

ppmm --version

Binary output: target/release/ppmm (or ppmm.exe on Windows).

Commands

Create & Initialize Projects

ppmm new <NAME>

Create a new Python project with scaffolding.

Options:

• -v, --version <VERSION> - Project version (default: 0.1.0)
• -d, --description <DESC> - Project description
• -g, --git - Initialize git repository
• -e, --no-venv - Skip virtual environment creation

Examples:

# Create basic project
ppmm new my-project

ppmm new my-project -v 1.0.0 -d "My awesome project" -g

# Create without venv
ppmm new my-project --no-venv

ppmm init

Initialize a Python project in the current directory.

Options:

• Same as ppmm new

Examples:

# Initialize in current directory
ppmm init

# Initialize with git
ppmm init -g

Package Management

ppmm add <PACKAGES>

Add one or more packages to the project.

Features:

• Installs to virtual environment automatically
• Supports version pinning (e.g., package==1.2.3)
• Updates project.toml automatically
• Validates package names

Examples:

# Add multiple packages
ppmm add requests flask numpy

# Add specific versions
ppmm add django==3.2.0 pillow==9.0.0

# Mix and match
ppmm add requests flask==2.0.0 numpy

ppmm rm <PACKAGES>

Remove packages from the project and environment.

Features:

• Removes from virtual environment
• Updates project.toml
• Validates package existence

Examples:

ppmm rm requests
ppmm rm flask numpy pandas

ppmm update

Update all packages to their latest versions from PyPI.

Features:

• Fetches latest versions from PyPI API
• Updates all packages atomically
• Reports failed updates

Examples:

ppmm update

Script Management

ppmm run <SCRIPT-NAME>

Execute a custom script defined in project.toml.

Features:

• Cross-platform command execution
• Access to virtual environment
• Real-time output streaming

Examples:

ppmm run test
ppmm run build
ppmm run dev

ppmm build

Run the build script defined in the [scripts] section of project.toml.

Features:

• Uses the project's virtual environment on PATH
• Cross-platform execution (cmd on Windows, sh -c on Linux/macOS)
• Warns if scripts.build is not defined

Examples:

# Ensure project.toml contains:
# [scripts]
# build = "python setup.py build"

ppmm build

ppmm bump <TYPE>

Automatically bump the project version following semantic versioning.

Arguments:

• major - Increment major version (1.0.0 → 2.0.0)
• minor - Increment minor version (1.0.0 → 1.1.0)
• patch - Increment patch version (1.0.0 → 1.0.1)

Features:

• Parses semantic versions (major.minor.patch)
• Strips alpha/beta suffixes before bumping
• Updates project.toml automatically
• Shows colored version bump info

Examples:

# Bump patch version
ppmm bump patch

# Bump minor version
ppmm bump minor

# Bump major version
ppmm bump major

Project Information

ppmm info

• Creates standard requirements.txt format
• Overwrites existing requirements.txt

Examples:

ppmm gen

# Equivalent to: pip freeze > requirements.txt

ppmm install

Install all packages from project.toml.

Features:

• Creates venv if missing
• Batch installs all packages
• Validates all packages exist

Options:

• -r, --requirements <FILE> - Install from requirements.txt instead

Examples:

# Install from project.toml
ppmm install

# Install from requirements.txt
ppmm install -r requirements.txt
ppmm install --requirements /path/to/reqs.txt

Project Configuration

project.toml Format

PPM uses TOML for project configuration. Here's the complete format:

[project]
name = "my-project"
version = "1.0.0"
description = "An awesome Python project"
main_script = "./src/main.py"

[packages]
# Production dependencies
requests = "2.28.0"
flask = "2.1.0"
numpy = "1.21.0"

[scripts]
# Custom scripts
test = "python -m pytest tests/ -v"
lint = "python -m pylint src/"
format = "python -m black src/"
build = "python setup.py build"
dev = "python -m flask run --debug"
upgrade-pip = "python -m pip install --upgrade pip"

Configuration Details

Project Structure

PPM creates the following structure for new projects:

my-project/
├── project.toml          # Project configuration
├── requirements.txt      # Auto-generated dependencies
├── venv/                 # Virtual environment
│   ├── bin/             # Executables (Linux/macOS)
│   ├── Scripts/         # Executables (Windows)
│   └── lib/             # Installed packages
├── src/
│   └── main.py          # Entry point
└── .gitignore           # Git ignore (if -g flag used)

Examples

Example 1: Web API Project

# Create project
ppmm new api-server -v 1.0.0 -d "REST API server" -g

# Add dependencies
ppmm add flask flask-cors flask-sqlalchemy

# Create scripts
# Edit project.toml to add:
# [scripts]
# dev = "python -m flask run"
# prod = "gunicorn main:app"

# Start development
ppmm start

Example 2: Data Science Project

# Create project
ppmm new data-analysis -d "Data analysis project"

# Add data science packages
ppmm add pandas numpy scipy matplotlib scikit-learn jupyter

# Generate requirements for sharing
ppmm gen

# Update all packages
ppmm update

Example 3: Migrate from pip

# Convert existing project
cd my-existing-project
ppmm init -g

# Install from existing requirements
ppmm install -r requirements.txt

# Generate new project config
ppmm gen

Cross-Platform Support

PPM is fully cross-platform and tested on:

• Windows - Full support, .exe extensions handled automatically
• macOS - Full support, uses bin/ for venv
• Linux - Full support, uses bin/ for venv

The tool automatically detects your platform and uses the correct paths and commands.

Troubleshooting

Virtual Environment Not Found

Problem: "Virtual Environment Not Found"

Solutions:

1. Create venv: ppmm new my-project (auto-creates)
2. Manually create: python -m venv venv
3. Use --no-venv flag if intentional

Package Installation Failed

Problem: "Package 'X' failed to install"

Solutions:

1. Check package name spelling
2. Verify package exists: pip search <package>
3. Check pip version: pip --version
4. Update pip: ppmm run upgrade-pip

Python Not Found

Problem: "python command not found"

Solutions:

1. Ensure Python is installed
2. Add Python to PATH
3. Use absolute path in scripts

Cross-Platform Issues

Windows:

• Use forward slashes in project.toml (scripts: "python -m pytest tests/")
• Paths are normalized automatically

Linux/macOS:

• Ensure execute permissions: chmod +x venv/bin/python
