🔭 Git Pulsar (v0.4.0)

Automated, paranoid git backups for students and casual coding.

Git Pulsar is a background daemon that wakes up every 15 minutes, commits your work to a secluded wip/pulsar branch, and pushes it to your remote. It ensures that even if your laptop dies, your uncommitted work is safe on the server—without polluting your main history.

---

⚡ Features

• Set & Forget: Runs silently in the background via launchd (macOS) or systemd (Linux).
• Non-Intrusive: Commits are pushed to a separate branch (wip/pulsar). Your main branch stays clean.
• Smart Checks:
  • Detects if the repo is busy (merging/rebasing) and yields.
  • Prevents accidental upload of large files (>100MB).
  • Auto-generates .gitignore for Python/LaTeX projects if missing.
• System Integration: Native desktop notifications on success or failure.

📦 Installation

macOS (Recommended)

Install via Homebrew to handle the daemon registration automatically.

brew tap jacksonfergusondev/tap
brew install git-pulsar
brew services start git-pulsar

Linux / Generic

Install via uv (or pipx) to isolate the environment, then register the systemd service.

uv tool install git-pulsar
git-pulsar install-service

🚀 Usage

1. Activate a Repository

Navigate to any project you want to back up and initialize Pulsar.

cd ~/University/Astro401
git-pulsar

This registers the path in the local registry (~/.git_pulsar_registry) and ensures the wip/pulsar branch exists.

2. Work Normally

You do not need to do anything else. Pulsar wakes up every 15 minutes to:

1. Check for changes.
2. Commit them to wip/pulsar.
3. Push to origin.

3. Retrieve Your Work

When you are ready to finalize your work, you can squash the backup history into your main branch:

git checkout main
git merge --squash wip/pulsar
git commit -m "Finalized assignment submission"

🛑 Stopping the Service

To deregister the background daemon and stop all backups:

git-pulsar uninstall-service

🔧 Requirements

• Python 3.12+
• Headless Auth: Your git authentication must be non-interactive (SSH keys or a cached Credential Helper). Pulsar runs in the background and cannot prompt for passwords.

🛠️ Development

This project uses modern Python tooling.

1. Clone and Install Dependencies:

   git clone [https://github.com/jacksonferguson/git-pulsar.git](https://github.com/jacksonferguson/git-pulsar.git)
   cd git-pulsar
   uv sync
   

2. Setup Pre-commit Hooks:

   pre-commit install
   

3. Run Tests: We use pytest for testing and hypothesis for property-based testing.

   pytest
