另见: Vim

Neovim is a highly extensible and open source text editor that aims to improve upon and modernize the popular Vim editor. It's designed to be a drop-in replacement for Vim, maintaining compatibility with most Vim plugins and configurations while offering additional features and improvements. Neovim focuses on extensibility, usability, and performance.

它引入了强大的插件架构，支持异步插件执行，这可以显著提升某些操作的性能。它还内置了终端模拟器，允许用户直接在编辑器中运行 shell 命令。该项目注重代码质量和可维护性，拥有简洁且文档完善的代码库，方便开发者贡献代码。

安装

Shell

要在不修改系统配置的情况下临时在 shell 环境中使用 Neovim，您可以运行：

$ nix-shell -p neovim

这样就能在当前 shell 中使用 Neovim 编辑器了。之后，您可以通过输入 nvim 来启动 Neovim。

系统设置

要在系统范围内安装 Neovim，使其可供所有用户使用，请将以下内容添加到您的配置中：

# /etc/nixos/configuration.nix 示例
environment.systemPackages = [
  pkgs.neovim
];

# 单用户安装（位于 ~/.config/nixpkgs/home.nix）
home.packages = [
  pkgs.neovim
];

使用 nixos-rebuild switch 或 home-manager switch 重建系统后，Neovim 将被安装并可使用。

配置

基础

# 全局配置
programs.neovim = {
   enable = true;
   defaultEditor = true;
};

<div lang="en" dir="ltr" class="mw-content-ltr">
# Home Configuration
</div>
programs.neovim = {
  enable = true;
  extraConfig = ''
    set number relativenumber
  '';
};

进阶

# 全局配置
programs.neovim = {
  enable = true;
  defaultEditor = true;
  viAlias = true;
  vimAlias = true;
  configure = {
    customRC = ''
      set number
      set cc=80
      set list
      set listchars=tab:→\ ,space:·,nbsp:␣,trail:•,eol:¶,precedes:«,extends:»
      if &diff
        colorscheme blue
      endif
    '';
    packages.myVimPackage = with pkgs.vimPlugins; {
      start = [ ctrlp ];
    };
  };
};

<div lang="en" dir="ltr" class="mw-content-ltr">
# Home Configuration
# You have to add the line below to set it as the default editor:
</div>
programs.neovim.defaultEditor = true;

框架

If you prefer not to configure your system manually, NixOS offers several predefined configurations and community-supported options. Here are a few of them:

• LazyVim
• AstroNvim
• NVChad

LazyVim, by default, will prevent loading plugins that are not managed by LazyVim. This includes all plugins installed via Nix. If you want to install plugins with both Nix and LazyVim, add the following to your LazyVim setup:

require("lazy").setup(lazyPackages, {
   performance = {
     reset_packpath = false, -- so that plugins outside of lazy can be loaded
   },
 })
 vim.cmd([[ packloadall]] ) -- load plugins outside of lazy

FHS 包装

You can create a custom neovim FHS wrapper

{
  buildFHSEnv,
  writeShellScript,
  neovim,
}:
buildFHSEnv {
  name = "nvim-fhs";
  targetPkgs = pkgs: [ neovim ];

  runScript = writeShellScript "nvim-fhs.sh" ''
    exec ${neovim}/bin/nvim "$@"
  '';
}

This FHS wrapper example is based on a contribution to nixpkgs. For an extended configuration that includes setting up mason.nvim with a similar FHS environment, see this NixOS/nixpkgs issue comment.
