Neovim

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.

В нем реализована мощная архитектура плагинов, позволяющая выполнять плагины асинхронно, что может значительно повысить производительность некоторых операций. Также в него встроен эмулятор терминала, позволяющий запускать shell-команды непосредственно в редакторе. В проекте особое внимание уделяется качеству и удобству сопровождения кода, а чистая, хорошо документированная кодовая база облегчает разработчикам внесение своего вклада.

Установка

Используя nix-shell

nix-shell -p neovim

Глобально

environment.systemPackages = [
  pkgs.neovim
];

После изменения вашей конфигурации, примените изменения выполнив:

sudo nixos-rebuild switch

Using Home Configuration

home.packages = [ 
  pkgs.neovim 
];

After updating your configuration, apply the changes by running:

home-manager switch

Советы и рекомендации

Location of Options

The home manager options are defined in the following Home Manager Options Manual.

The global options are listed on MyNixOS.

Neovim Nightly

Have a look at the Neovim Nightly Overlay to install the most recent current nightly version of Neovim.

You can run the master version via the following command:

nix run "github:nix-community/neovim-nightly-overlay"

Pre-Configured Configurations

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

Another excellent option is LunarVim. The development community describes it as "an IDE layer for Neovim with sane defaults." LunarVim includes an installer/updater for LSP modules and other features. It can be installed via the lunarvim package from nixpkgs and is started with the lvim command.

Конфигурация LunarVim хранится в ~/.config/lvim.
