Key Features

  • Nixvim for Declarative Configuration: Leverage Nix expressions for a clean and maintainable Neovim setup. Easily add, remove, or update plugins, LSP servers, and other components.
  • Consistent Environments: Reproduce your Neovim setup effortlessly on any system with Nix installed.
  • Plugin Management: Seamlessly manage plugins using Nixvim's declarative configuration.
  • LSP Integration: Built-in support for language servers and completion tools.
  • Customization: Adapt to your preferences with additional plugins, themes, and key mappings (details below).

Prerequisites

Installation

Option 1: Using nix run (Easiest):

nix run github:khaneliman/khanelivim

Option 2: Adding as a Flake Input:

In your system's Nix configuration (e.g., ~/.config/nixpkgs/flake.nix or ~/.config/nixpkgs/home.nix), add the following:

    inputs = {
      nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";  # Or your preferred channel
      khanelivim.url = "github:khaneliman/khanelivim";
    };

    outputs = { self, nixpkgs, khanelivim }: {
      # ... your other configuration ...

      # Add to your system packages or devShell if you want to make it available system-wide
      packages = with nixpkgs; [
        khanelivim.packages.${system}.default
      ];

      # Or, use in a devShell:
      devShells.default = nixpkgs.mkShell {
        nativeBuildInputs = [ khanelivim.packages.${system}.default ];
      };
    };

Option 3: Build and run locally:

nix build . && ./result/bin/nvim

Updating

nix flake update

Rebuild your Neovim:

nix build

Run the updated Neovim:

./result/bin/nvim

Enter Nix Shell:

cd ~/.config/nvim nix develop

*(If you have direnv installed, it should automatically activate the environment when you cd into the directory.)

LSP (Language Server Protocol) Configuration

This configuration emphasizes LSP support to enhance your coding experience with features like:

  • Diagnostics: Visual feedback for errors, warnings, hints, and information using symbols (e.g., ❌ for errors).
  • Navigation: Quickly jump to definitions, references, implementations, and type definitions.
  • Code Actions: Access context-aware suggestions for code improvements.
  • Hover Information: Get detailed information about symbols by hovering over them.
  • Rename: Refactor symbols accurately across your codebase.
  • Formatting: Automatically format your code (either through a dedicated formatter or LSP capabilities).

Key LSP Plugins:

  • lspkind: Provides informative icons for LSP completions.
  • lsp-lines: Enhances the display of LSP diagnostics within the code lines.
  • lsp-format: Integrates LSP formatting capabilities (if you're not using the conform-nvim plugin).
  • nvim-jdtls: Configures the Java LSP server (jdtls).

LSP Servers:

The configuration includes a comprehensive list of LSP servers to support various programming languages, including:

  • Bash/Shell (bashls)
  • C/C++ (ccls, clangd)
  • CMake (cmake)
  • C# (csharp-ls)
  • CSS/Less/SCSS (cssls)
  • Docker (dockerls)
  • JavaScript/TypeScript (eslint, tsserver)
  • F# (fsautocomplete)
  • Godot (gdscript)
  • HTML (html)
  • Java (java-language-server or jdt-language-server)
  • JSON (jsonls)
  • Lua (lua-ls)
  • Markdown (marksman)
  • Nix (nil-ls)
  • Python (pyright)
  • Rust (rust-analyzer, optionally if not using rustaceanvim)
  • SQL (sqls)
  • TOML (taplo)
  • YAML (yamlls)

Each server has specific settings tailored to its language, such as filetype associations, initialization options, and formatting configurations.

Custom Keymappings:

The configuration defines key mappings for common LSP actions under the <leader>l prefix:

  • <leader>la: Code actions
  • <leader>ld: Go to definition
  • <leader>lf: Format code (in visual mode)
  • <leader>lD: Find references
  • <leader>lt: Go to type definition
  • <leader>li: Go to implementation
  • <leader>lh: Hover for information
  • <leader>lr: Rename symbol

Additional Notes:

  • You can enable/disable specific LSP servers based on your needs.
  • The nvim-jdtls plugin configuration is separate due to its specific requirements.
  • The lsp-format plugin is conditionally enabled if you're not using conform-nvim for formatting.
  • You can further customize the LSP behavior in your Neovim config.
