Neovim

Catalog v8.

Enables the Neovim text editor through the NixOS programs.neovim option.

Select

Choose it as the editor in the [shell] table:

[shell]
editor = "neovim"

Apply the change after editing limanix.toml. editor = "astronvim" also installs Neovim, configured as AstroNvim.

Versions

Neovim comes from the catalog's base Nixpkgs revision. This module has no version lines. Inside the VM, nvim --version shows the installed version.

Use

Inside the VM, open a file with the nvim command:

nvim notes.md

The vi and vim aliases also launch Neovim.

Make Neovim the default editor

The module leaves EDITOR at its NixOS default, nano. To make Neovim the editor for programs that read EDITOR, such as git commit, add a custom module with this setting:

{
  programs.neovim.defaultEditor = true;
}

Language servers

The module does not configure Neovim's LSP client. To use gopls from the Go module or rust-analyzer from the Rust module, configure Neovim's LSP client to start the server. Editor integration describes the options.

Configuration and integration

Boundary	Contract
Settings	programs.neovim.*, including package, aliases and default editor
Personal state	~/.config/nvim/, plus native XDG data, state and cache directories
Integration	Language modules supply servers; plain Neovim needs your LSP configuration
Services and capabilities	No daemon or language-support provider declarations

Corner cases

Case	Behavior or next step
No completion or LSP attachment	This module supplies the editor; select AstroNvim for the catalog setup
Default editor	Set programs.neovim.defaultEditor = true when you want to replace the base editor
User configuration	Existing Neovim configuration remains user-owned
