About:
Karn is a command-line utility that helps developers manage multiple Git identities across different projects. It allows you to define profiles for various email addresses and SSH keys, automatically configuring Git settings based on the current directory. This tool simplifies the workflow for users who contribute to both personal and professional repositories, ensuring the correct identity is always used.

Key Features:

Profile-based management for Git user and signing keys
Automatic context switching based on project directories
Simple command-line interface for easy integration
Supports GPG key configuration for signed commits

Use Cases:

Managing separate Git identities for work and personal projects
Switching between open-source contributor and corporate email addresses
Ensuring commit signatures use the correct GPG key for different organizations

Alternatives:

git-profile-manager – Similar functionality, but Karn is specifically designed for Homebrew users and focuses on directory-based context switching.
Manual git config – Using global or local git config requires manual switching, whereas Karn automates this process based on project location.
