Git Configuration Based on Tags

This example shows how to use HermitGrab’s tag system to manage Git configurations for different contexts like work and personal use. It demonstrates the power of tag-based conditional installs and detectors.

Highlights

Tag-based Configuration: Select Git config based on +work or +personal.
Custom Detectors: Checks for the presence of tools like Git and 1Password.
Multi-Context Setup: Automates email, user name, and signing key.
