My Neovim Configuration

Features

• Handy and Smoothy: There will always be a panel to remind you when you forget your key settings. There will always be a short keystroke to help you get to the place you want to jump to. There will always…
• Powerful coding experience: nvim-lspconfig powered great LSP experient.
• Fancy looking: Well designed, denoised, uncluttered UI. Talk is cheap, see the gallery.
• Great Performance: Lazy loading anywhere, you will never have to worry about accidental opening of a file larger than 10000 loc can freeze your terminal.

Getting Start

This configuration is compatible with neovim 0.10+ version.

git clone --depth=1 https://github.com/Avimitin/nvim.git ~/.config/nvim

Finally, input nvim to open the editor, and all plugins will be downloaded automatically.

nvim

To use this in your home-manager, you can use the xdg.configFile attribute:

{ pkgs }:
{
  xdg.configFile = {
    neovim = {
      target = "nvim";
      source = pkgs.fetchFromGitHub {
        repo = "nvim";
        owner = "Avimitin";
        rev = "...";
        hash = "...";
      }
    };
  };
}

Diagnostic error/warning/hint are highlighted with undercurl, please use kitty, wezterm or anyother terminal that support undercurl.

If you are using tmux, to have a correct display, you can try my configuration below:

# (MUST) Enable 256 color for tmux
set -g default-terminal "tmux-256color"

# (Optional, choose any of them)
# Enable true color and undercurl for wezterm
set -as terminal-features ",wezterm*:RGB"
set -as terminal-features ",wezterm*:usstyle"
# Same as above, but for kitty. (kitty doesn't support Windows so I have to keep two configuration here)
set -as terminal-features ",kitty*:RGB"
set -as terminal-features ",kitty*:usstyle"
# Same as above, but for SSH. This is useful because I am using `alias ssh="TERM=xterm-256color exec ssh"`
set -as terminal-features ",xterm-256color*:RGB"
set -as terminal-features ",xterm-256color*:usstyle"
set -as terminal-overrides ",xterm*:Tc"

# (MUST) This hijack the neovim undercurl char sequence, to avoid tmux escape them.
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'

Treesitter parsers in nix

• For normal user: make sure gcc is installed, then run :TSInstall <language> to compile and install corresponding treesitter plugin
• For nix user: you can add this repository as an overlay and use the pre-bundled neovim:

# flake.nix
{
  description = "Simple home-manager neovim configuration";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    my-neovim.url = "github:Avimitin/nvim";
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { self, nixpkgs, flake-utils, home-manager, my-neovim }: {
    homeConfiguration = home-manager.lib.homeManagerConfiguration {
      # import my overlay, it will add a new `neovim-nightly` derivation into your nixpkgs
      pkgs = import nixpkgs { system = "x86_64-linux" overlays = [ my-neovim.overlays.default ];  };
      modules = [
        ({ pkgs }: {
          # Then add the pre-bundled neovim into your home configuration
          home.packages = [
            pkgs.neovim-nightly
          ];
        })
      ];
    };
  };
}
