Developed the initial Partial-Region Formatting Plugin for the nix-community/nixvim repository, enabling Neovim to format only user-modified text regions rather than entire files. This targeted approach reduced unnecessary formatting changes, improved editing speed, and enhanced code consistency during development. The work involved designing maintainable plugin scaffolding and integrating with the LSP-format workflow to support delta-based formatting. Leveraging skills in Neovim configuration, Nix package management, and plugin development, the implementation established a foundation for more precise and efficient code editing. The project was delivered in Nix and Lua, focusing on maintainability and a smoother developer experience without introducing major bug fixes.
