To start configuring, just add or modify the nix files in ./config. If you add a new configuration file, remember to add it to the config/default.nix file

LSP (C/Rust focused)

• blink.cmp: A high-performance completion engine (modern alternative to nvim-cmp).
• lspconfig: The standard interface for connecting to Language Servers.
• lspsaga.nvim: A UI layer for LSP providing breadcrumbs, floating windows, and hover actions.
• clangd-extensions.nvim: Enhances the C/C++ development experience with inlay hints and better type info.
• rustaceanvim: A heavy-duty plugin for Rust development, including advanced rust-analyzer integration.
• none-ls.nvim: Bridges the gap for formatters and linters that don't have a standalone LSP (successor to null-ls).

UI

• lualine.nvim: A fast and customizable statusline.
• bufferline.nvim: Adds a tab-like bar at the top for managing open buffers.
• noice.nvim: Overhauls the command line, messages, and notification UI.
• markview.nvim: A modern Markdown previewer that renders directly in the buffer.
• nvim-ufo: High-performance code folding with better visual indicators.
• nvim-colorizer.lua: Highlighting of HEX/RGB color codes directly in your code.
• nvim-web-devicons: Provides file type icons used by many other plugins.

Treesitter (Syntax)

• nvim-treesitter: The core engine for advanced syntax highlighting and code parsing.
• treesitter-context: Shows the current function/class context at the top of the screen while scrolling.
• treesitter-textobjects: Adds smart selection based on code structure (e.g., select an entire function).

Git Integration

• gitsigns.nvim: Shows git diffs in the sign column and allows hunk management.
• codediff.nvim: Provides a dedicated interface for viewing and managing code diffs, merges.

Utility & Navigation

• neo-tree.nvim: Sidebar-based file explorer.
• trouble.nvim: A pretty list for showing LSP diagnostics, references, and search results.
• smart-splits.nvim: Directional navigation between Neovim splits.
• undotree: Visualizes the undo history tree, allowing you to go back to previous states.
• todo-comments.nvim: Highlights and searches for tags like TODO, FIXME, or NOTE.
• persistence.nvim: Automatically saves and restores your sessions. -- not configured properly yet
• comment.nvim: Simple and powerful keybindings for commenting out code.
• nvim-autopairs: Automatically closes brackets, quotes, and parentheses.
• lz-n: A plugin for lazy-loading your configuration to speed up startup time.

Debugging (DAP)

• nvim-dap: The Debug Adapter Protocol implementation for nvim.
• nvim-dap-ui: Provides IDE-like interface for debugger (variables, stack trace, etc.).
• nvim-dap-virtual-text: Displays variable values as virtual text next to the code during debugging.

Ecosystem Suites

• snacks.nvim: A collection of small plugins (dashboard, picker, etc.).
• mini.nvim: A collection of small plugins (keymap hints, etc.)

Development & LSP Utilities

• <leader>cv (ShowConversions): Opens a floating window showing the selected text/word in Hex, Binary, Decimal, and Base64. You can copy directly from this window.
• <leader>cl (CopyCursorLocation): Generates a "permalink" (relative path + line number) from the Git root and copies it to the system clipboard.
• <leader>ci (toggleInlayHints): Toggles LSP inlay hints on/off with a notification.
• <leader>ch (ToggleHex): Toggles the current buffer between raw text and Hex representation using xxd.
• gx (OpenUnderCursor): Opens the URL or file path under the cursor using xdg-open.
• <leader>ct (searchTag): Jumps to the definition of the word under the cursor using the tags file.

UI & Toggle Controls

• <leader>uv (Toggle Virtual Text): Toggles diagnostic virtual text (inline LSP diagnostics) while preserving your custom icon/prefix settings.
• <leader>ul (ToggleLineNumber): Switches between showing standard line numbers and hiding them.
• <leader>uL (ToggleRelativeLineNumber): Switches between relative line numbers and standard numbers.
• <leader>uw (ToggleWrap): Toggles line wrapping for the current buffer.
• <leader>cz (Zen Mode Lite): Simulates a "Zen" mode by toggling a large foldcolumn to center the text.

Movement & Editing

• J / K (Visual Mode): Moves the selected block of code up or down while maintaining indentation and selection.
• J (Normal Mode): Joins the line below to the current line but keeps the cursor at its original position.
• <C-d> / <C-u>: Scrolls page down or up while keeping the cursor centered on the screen.
• <leader>fy: Gathers every match of the current search pattern into the system clipboard.

If you have nix installed, you can directly run my config from anywhere:

nix run 'github:danylo-volchenko/nixvi'

This nixvim flake will output a derivation that you can easily include in either home.packages for home-manager, or environment.systemPackages for NixOS. Or whatever happens with darwin?

You can add my nixvim configuration as an input to your NixOS configuration like:

{
 inputs = {
    nixvim.url = "github:danylo-volchenko/nixvi";
 };
}

With the input added you can reference it directly.

{ inputs, system, ... }:
{
  # NixOS
  environment.systemPackages = [ inputs.nixvim.packages.${pkgs.system}.default ];
  # home-manager
  home.packages = [ inputs.nixvim.packages.${pkgs.system}.default ];
}

The binary built by nixvim is already named as nvim so you can call it just like you normally would.

Another method is to overlay your custom build over neovim from nixpkgs.

This method is less straight-forward but allows you to install neovim like you normally would. With this method you would just install neovim in your configuration (home.packges = with pkgs; [ neovim ]), but you replace neovim in pkgs with your derivation from nixvim.

{
  pkgs = import inputs.nixpkgs {
    overlays = [
      (final: prev: {
        neovim = inputs.nixvim.packages.${pkgs.system}.default;
      })
    ];
  }
}
