jpm - Just Package Manager

This is a vibe coding project cause I'm too lazy :) And this project is for my own system only, so use it on your own risk.

Overview

jpm is a simple, bash-based package manager built from scratch for Linux. It handles package installation, dependency management, and uninstallation with reverse dependency checks.

Features

• Install: Recursively installs dependencies.
• Uninstall: Prevents breaking other packages by checking reverse dependencies.
• Remote Repository: Auto-clones package repository on first use.
• Source Handling:
  • Downloads from HTTP/HTTPS URLs.
  • Clones git repositories (supports .git, git://, and git+ prefixes).
• Integrity: Supports MD5 and SHA256 checksum validation.
• Tracking: Keeps track of installed files for clean removal.

Installation

sudo make install

Variable	Default	Description

Package Format
