yonvim

My personal Neovim distribution.

Notice

I'm now using LazyVim and Yonvim is no longer maintained.

Requirements

• Nix (Yonvim currently supports Nix Flakes only)
• Neovim 0.10.x

Installation

Add the following to your flake.nix:

{
  inputs = {
    yonvim = {
      url = "github:sei40kr/yonvim";
      # Necessary if you want to use the same version of Neovim in both Flakes
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
}

Then, add the following to your Nix configuration:

{
  environment.systemPackages = [
    inputs.packages.${pkgs.stdenv.hostPlatform.system}.yonvim
    inputs.packages.${pkgs.stdenv.hostPlatform.system}.yonvim-qt
  ];
}

Then, create ~/.config/yonvim/init.lua and put the following:

require("yvim").setup {}

Configuration

You can write your configurations in ~/.config/yonvim/init.lua.

require("yvim").setup {
  -- Your configurations here

You need to log in to GitHub to use Copilot by running :Copilot setup.

---

copilot.completion.filetypes is a table that has filetypes as keys and boolean or a function that returns a boolean as values. The default value is:

{
    gitcommit = false,
    gitrebase = false,
    hgcommit = false,
    sh = function()
        return not vim.endswith(vim.api.nvim_buf_get_name(0), ".env")
    end,
    svn = false,
    cvs = false,
    ["."] = false,
}

As you can see, Copilot completion is disabled for some filetypes by default. This is because it is not recommended to enable Copilot for those filetypes since they often contain sensitive information and Copilot needs to send the content of the buffer to GitHub to get completions.

You can override this behavior by setting copilot.completion.filetypes by your own risk.

Keymaps

You can add user-defined keymaps to keymaps.

Example

yvim.setup {
    keymaps = {
        { "<M-Left>",  "<Cmd>BufferLineCyclePrev<CR>", desc = "Go to previous buffer" },
        { "<M-Right>", "<Cmd>BufferLineCycleNext<CR>", desc = "Go to next buffer" },
        -- { lhs, rhs, mode = ..., silent = ..., remap = ..., nowait = ..., desc = ... },
    }
}

Development

Add a plugin

First, you need to generate a Nix derivation for the plugin by running:

cd packages/yonvim/plugins
./plugins.py add nvimdev/dashboard-nvim

This will add the following to packages/yonvim/plugins/generated.nix:

{
  # ...
  dashboard-nvim = vimUtils.buildVimPlugin {
    pname = "dashboard-nvim";
    version = "2023-11-10";

    src = fetchFromGitHub {
      owner = "nvimdev";
      repo = "dashboard-nvim";
      rev = "63df28409d940f9cac0a925df09d3dc369db9841";
      hash = "sha256-LNjYIRL5xZyLgFkoTu3K5USOfk1mtaXe5RhKBAbzYRw=";
    };

    dontBuild = true;

    meta.homepage = "https://github.com/nvimdev/dashboard-nvim";
  };
  # ...
}

In build time, Lazy.nvim spec that just specifies the source directory of the plugin will be added:

return {
    -- ...
    {
        dir = "/nix/store/wji57kh1j08rvvpynp8wwvkakahg0nly-vimplugin-dashboard-nvim-2023-11-10",
        name = "dashboard-nvim",
        pin = true,
    },
    -- ...
}

You can manually set the rest of the Lazy.nvim spec of the plugin by its name.

{
    "dashboard-nvim"
    dependencies = { "nvim-web-devicons" },
    event = "VimEnter",
    config = function()
        -- ...
    end,
}

Update a plugin

To update a plugin, run:

cd packages/yonvim/plugins
./plugins.py update dashboard-nvim

Or you can update all plugins by running:

cd packages/yonvim/plugins
./plugins.py update

This will make many requests to GitHub API to check if the plugin is updated, and it may cause GitHub API rate limit exceeded. In that case, you can set your GitHub personal access token to GITHUB_API_TOKEN environment variable.

cd packages/yonvim/plugins
GITHUB_API_TOKEN='<your token>' ./plugins.py update

See ./plugins.py --help for details.
