A modular Neovim configuration built with Nix flakes, designed to create different Neovim variants optimized for various development environments.

• Modular Architecture: Extensible configuration system with reusable components
• Language-Specific Variants: Optimized configurations for different programming languages
• Nix Flakes: Reproducible builds and dependency management
• Development Environment: Complete dev setup with formatting and pre-commit hooks

# Run the lightweight core configuration
nix run github:hasundue/nvim#core

# Or run the full configuration with all plugins
nix run github:hasundue/nvim#full

# Or try a language-specific variant
nix run github:hasundue/nvim#python

Add to your flake.nix:

{
  inputs.nvim.url = "github:hasundue/nvim";
  
  outputs = { nvim, ... }: {
    # Use as a package
    environment.systemPackages = [ nvim.packages.${system}.full ];
    
    # Or in a development shell
    devShells.default = pkgs.mkShell {
      buildInputs = [ nvim.packages.${system}.python ];
    };
  };
}

# Run a neovim variant
nix run .#nix

# Enter a development shell with a specific variant
nix develop .#lua

# Enter development environment
nix develop dev/

# Run the full variant in development mode
nix run dev/

This provides:

• Full Neovim configuration with all plugins
• Code formatting tools (nixfmt, stylua)
• Pre-commit hooks
• Live reloading during development

• Overlays (overlays/): Nix overlays defining the modular architecture
• Configurations (nvim/plugin/): Core Neovim settings and options
• Plugin Configs (nvim/after/plugin/): Individual plugin configurations
• Language Support (nvim/after/ftplugin/): Filetype-specific settings
• Utilities (nvim/lua/my/): Custom Lua utilities and helpers

• LSP: Native LSP client with language-specific configurations
• Completion: blink.cmp for fast autocompletion
• UI: Kanagawa theme, Lualine status line, Noice command line
• Navigation: Telescope fuzzy finder, Oil file manager
• Git: Gitsigns for git integration
• Editing: Treesitter for syntax highlighting, nvim-surround for text objects
