## 添加 init.lua
vim ~/.config/nvim/init.lua

-- bootstrap lazy.nvim
-- ./lua/lazynvim-init.lua
require("lazynvim-init")

## 设置 lazynvim
vim ~/.config/nvim/lua/lazynvim-init.lua

-- 1. 准备lazy.nvim模块（存在性检测）
-- stdpath("data")
-- macOS/Linux: ~/.local/share/nvim
-- Windows: ~/AppData/Local/nvim-data
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({
		"git",
		"clone",
		"--filter=blob:none",
		"https://github.com/folke/lazy.nvim.git",
		"--branch=stable", -- latest stable release
		lazypath,
	})
end
--
-- 2. 将 lazypath 设置为运行时路径
-- rtp（runtime path）
-- nvim进行路径搜索的时候，除已有的路径，还会从prepend的路径中查找
-- 否则，下面 require("lazy") 是找不到的
vim.opt.rtp:prepend(lazypath)

-- 3. 加载lazy.nvim模块
-- require("lazy").setup({})
-- 在 ~/.config/nvim/lua/plugins 安装插件
require("lazy").setup("plugins")

## 打开 nvim 验证 lazynvim
:Lazy

## 安装 plugin
mkdir -p ~/.config/nvim/lua/plugins
vim ~/.config/nvim/lua/plugins/plugin-lualine.lua

return {
    {
        'nvim-lualine/lualine.nvim',
        config = function()
            require('lualine').setup()
        end
    }
}

## 使用 vim-plug: https://github.com/junegunn/vim-plug
## 存放在 ~/.config/nvim，避免与 vim 冲突
curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

## 需要安装 pynvim
## python3 -m pip install --user --upgrade pynvim
## 安装相关的插件，位置在：~/.config/nvim/plugged
vim ~/.config/nvim/init.vim

"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
"如果vim插件管理器没有安装则自动安装
