Description
How Git Works (Wizard Zines). Many programmers only work with a few Git commands, such as commit and push, and panic when they encounter errors like “Detached HEAD.” How Git Works aims to dispel this fear. Instead of teaching commands, Julia Evans delves into Git’s internal data structures, explaining that Git is actually a collection of objects (Blobs, Trees, Commits) that store the history of a project. By understanding this mental model, all Git commands make logical sense.
The book then explores the concepts of branching and merging, showing that a branch is really nothing more than a pointer to a commit. The author focuses on the horror scenarios that can cause code to be lost, and then teaches how to restore it using Git’s built-in tools. This book empowers the reader to master Git instead of blindly using it, and to manage and fix the state of the repository with complete peace of mind in times of crisis.
