Git worktrees allow developers to work on multiple branches simultaneously within the same repository, but creating and managing them manually can be cumbersome. The author, frustrated with the tedious setup, created a tool called tree-me. This tool simplifies the process by automating worktree creation and organization, reducing the mental overhead involved. With tree-me, you can easily create worktrees using a straightforward command like `tree-me create <branch>`. It automatically detects the repository name, default branch, and organizes worktrees in a predictable directory structure, such as `~/dev/worktrees/<repo-name>/<branch-name>`. The tool also supports GitHub pull requests by allowing users to check out PRs directly without complex commands. It integrates features like auto-changing directories after creation and tab completion for commands, enhancing user experience. The author emphasizes that tree-me does not replicate the functionality of Git but rather adds a layer of organization and convenience. It’s designed to be minimal, requiring no setup beyond placing the script in your PATH and enabling a couple of shell features. This approach makes it accessible for developers working across various repositories and projects without getting bogged down in unnecessary configuration.
