dotdrop is a command-line tool for managing dotfiles across multiple hosts using profiles, Jinja2 templating, actions, and transformations. It stores dotfiles in a Git repository and deploys them to target systems, allowing different configurations per host or environment. The architecture is modular: separate Python modules handle each operation (install, compare, update, import, remove, uninstall), with a central dispatcher in `dotdrop.py`. Configuration is defined in YAML (or optionally TOML) files that specify dotfiles, profiles, variables, actions, and transformations. Key entry points are the CLI subcommands invoked via `dotdrop <command>`. Data flows involve parsing the config, aggregating imported configs and variables, then executing file operations (copy, symlink, diff) with optional template rendering and shell commands. External dependencies include Jinja2, docopt, PyYAML, and optional libraries for TOML support and system detection. The codebase is well-tested with both Python unit tests and a large suite of Bash integration tests, and it is distributed via PyPI, Homebrew, AUR, Snap, and other channels.
