Multi-Package Manager CLI (mg)

mg is a cross-ecosystem package management tool that supports multiple package managers (such as cargo, npm, pnpm, yarn, pip, pdm, and poetry), providing a unified command-line interface. By automatically detecting project types, mg intelligently invokes the corresponding package manager, simplifying package management operations in cross-language development.

Features

• Cross-ecosystem support: Supports package managers for ecosystems like Rust, Node.js, and Python.
• Automatic project type detection: Automatically selects the package manager based on project files (e.g., Cargo.toml, package.json, pyproject.toml, etc.).
• Unified command interface: Provides unified commands such as add, remove, upgrade, and analyze.
• Dynamic parameter support: Allows passing arbitrary package manager parameters and supports native command formats.
• Colored output: Uses colored terminal output to enhance readability.
