guse

⚡ Effortless Git user profile switching — powered by Rust.

guse is a fast and intuitive command-line tool to manage and switch between multiple Git identities across projects.
It handles user.name, user.email, and even your SSH remote configuration automatically, using simple profile-based rules.

Managing Git Identities

Working across different Git repositories often requires switching between multiple identities.
Manually updating user.name, user.email, and remote URLs can be repetitive and error-prone.

guse automates these steps using profile-based configuration, so each repository uses the correct settings without manual edits.

✨ Features

• 🔁 Switch Git user.name / user.email per repository
• 🔐 Automatically update git remote with SSH host
• 📝 Add, update, and remove profiles interactively
• 💾 Profile settings stored in a simple TOML file

🚀 Quick Start

Install

macOS

# Download the latest macOS binary from the release page
curl -LO https://github.com/jeonbyeongmin/guse/releases/latest/download/guse-x86_64-apple-darwin.tar.gz

# Extract the archive
tar -xzvf guse-x86_64-apple-darwin.tar.gz

# Make it executable
chmod +x guse-x86_64-apple-darwin

# (Optional) Move to your PATH
sudo mv guse-x86_64-apple-darwin /usr/local/bin/guse

Windows

1. Download guse-x86_64-pc-windows-gnu.zip from the latest release page.
2. Extract the zip file and place guse-x86_64-pc-windows-gnu.exe wherever you like.
3. (Optional) Rename the file to guse.exe.
4. (Optional) Add the folder to your system PATH.

Linux

# Download the latest Linux binary from the release page
curl -LO https://github.com/jeonbyeongmin/guse/releases/latest/download/guse-x86_64-unknown-linux-gnu.tar.gz

# Extract the archive
tar -xzvf guse-x86_64-unknown-linux-gnu.tar.gz

# Make it executable
chmod +x guse-x86_64-unknown-linux-gnu

# (Optional) Move to your PATH
sudo mv guse-x86_64-unknown-linux-gnu /usr/local/bin/guse

Usage

After installation, you can run the following command in your terminal:

guse

🛠️ Usage

Add a new profile

guse add personal

You'll be prompted to enter:

• Git user.name
• Git user.email
• SSH host alias (auto-detected from ~/.ssh/config)

Switch to a profile

# Select profile interactively
guse switch

# Specify profile name directly
guse switch personal

This will:

• Set the Git name/email for the current repository
• Rewire the remote origin URL to use the associated SSH host

Show current Git configuration

guse show

List available profiles

guse list

List configured SSH hosts (from ~/.ssh/config)

guse list-ssh

Update a profile

# Select profile interactively
guse update

# Specify profile name directly
guse update work

Delete a profile

# Select profile interactively
guse delete

# Specify profile name directly
guse delete work

🧠 How It Works

Profiles are stored in a .toml file at:

~/.guse-profiles.toml

Each profile includes:

[personal]
name = "byeongmin.jeon"
email = "jeonbyeongmin@personal.com"
ssh_host = "github-personal"

The ssh_host must match a Host alias in your ~/.ssh/config file.

🔐 Example ~/.ssh/config

Host github-personal
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_ed25519_personal

Host github-work
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_ed25519_work
