git-tunnel 0.1.0

Visualize git history as per-machine tunnels in your terminal

git-tunnel

Visualize your git history as per-machine tunnels in the terminal.

If you work across multiple machines — a MacBook, a Workstation, a Server — git log treats them all the same. git-tunnel splits each machine into its own colored column so you can see at a glance where every commit was made.

  ■ pre git-tunnel   ■ MacBook   ■ Workstation

Commits made before git-tunnel was installed appear in a plain white pre git-tunnel column — no history rewriting, no warnings.

---

Install

pip install git-tunnel

Or with uv:

uv tool install git-tunnel

---

Setup (once per machine)

Run the interactive setup:

git-tunnel install

This will:

• Ask for a device name (e.g. MacBook, Workstation, Server)
• Set git config --global user.device
• Install the prepare-commit-msg hook globally
• Point git config --global core.hooksPath at the hook

From this point on, every commit you make will automatically get a [device:YourDevice] tag appended to the message — silently, without you doing anything.

---

Usage

Inside any git repo:

git-tunnel

---

How it works

git-tunnel uses a global prepare-commit-msg hook that appends a [device:X] tag to every commit message, where X comes from git config --global user.device.

Your user.name is never touched — it stays clean for collaboration. The device tag lives in the commit message body and is stripped from the display in the tunnel view.

---

Multiple machines

Set a different device name on each machine:

# MacBook
git-tunnel install  # enter "MacBook" when prompted

# Workstation
git-tunnel install  # enter "Workstation" when prompted

# Server
git-tunnel install  # enter "Server" when prompted

Since the hook is global, it applies to every repo on that machine automatically.

---

Zero dependencies

git-tunnel uses only the Python standard library and git itself. No third-party packages required.
