Variants

nvix exports three pre-built Neovim binaries. Each is a nixvim package assembled from plugin modules.

---

bare

Lean variant for reviewing AI-made changes (diffs, hunks, lazygit) and quick edits on servers or ISOs. No LSP, completion, bufferline or image support.

Ships both nvim and an ai-nvim bin alias (nixvim only supports fixed vi/vim aliases), so it can sit next to other variants in home.packages.

Module	What it does
common	Options, keymaps, clipboard (OSC52 over SSH), icons, colorscheme, which-key, flash, comment, surround, autopairs, lz-n
git	Gitsigns, diffview, git-conflict
snacks	Snacks.nvim: lazygit float (<leader>gg), picker, dashboard, notifier, bigfile - image support off, git + lazygit bundled, ruby provider disabled (works standalone on a fresh machine)
treesitter	Syntax highlighting (33 curated grammars, regex fallback), context, mini.ai

core (default)

Everything in bare, plus buffer and UI niceties - note it uses the full treesitter grammar set (328 grammars) and snacks image support:

Module	What it does
buffer	Bufferline (tabs), harpoon file navigation
ux	Colorizer, dressing (better UI), lastplace, fidget (LSP notifications), windows.nvim
noice	UI replacement for cmdline, messages, notifications
lualine	Statusline (transparent, global)
firenvim	Neovim in browser textareas (opt-in, takeover = never)
leetcode	LeetCode solver (custom fork)
blink-cmp	Completion engine (blink.cmp + luasnip), Copilot integration
lang	Language servers: Nix, Python, Rust, Lua, Shell, TOML, Typst, Haskell, Web (TS, HTML, CSS, Tailwind, Svelte, JSON, ESLint, Biome), Markdown (obsidian, render-markdown, glow, markdown-preview, img-clip), HTTP (kulala)
lsp	All lspconfig servers (auto-enabled, package = null → use system PATH), lspsaga, trouble, tiny-inline-diagnostic, nvim-ufo (folding), conform.nvim (formatter)
autosession	Session persistence with git-branch awareness
ai	Copilot (suggestions + chatgpt plugin)

full

Everything in core, plus:

Module	What it does
tex	Vimtex, texlab (LSP), texpresso (live preview), full texlive scheme

Module composition

# packages/default.nix
bareModules = [ common git treesitter bareExtras ];
coreModules = [ common buffer ux snacks noice git lualine firenvim
  leetcode treesitter blink-cmp lang lsp autosession ai ];
fullModules = coreModules ++ [ tex ];

bareExtras is an inline module in packages/default.nix that re-imports snacks with image deps dropped, git+lazygit bundled, ruby provider off and treesitter grammars curated to 33.

Each list is passed to nixvim.legacyPackages.makeNixvimWithModule, which assembles a wrapped nvim binary.
