This is a personal configuration repository (dotfiles) for macOS, containing settings for Sublime Text, Terminal, oh-my-zsh, Git, and various shell scripts. It is not a software application but rather a collection of user environment configurations and utility scripts. The repository is well-organized with categorized directories for different tools (Sublime, Terminal, Archive). It includes a custom terminal theme 'GuoFeng', shell aliases and functions, git configuration, and Sublime Text snippets. The most notable reusable component is a bash script to rewrite Git commit author information across all branches. While not a production application, the configurations reflect a thoughtful, minimalist approach to tooling, with emphasis on native macOS apps and open-source alternatives.
