Zimfw is a Zsh configuration framework and plugin manager. It provides a CLI tool (zimfw) that installs, updates, and manages Zsh modules defined in a ~/.zimrc file. The tool generates a static initialization script (init.zsh) for fast shell startup by preprocessing module definitions. It supports multiple installation tools (git, degit, mkdir) and handles features like conditional module loading, submodules, and on-pull commands. The architecture is monolithic but modular in design, with clear separation between module parsing, tool execution, and script generation.
