neovim 从0开始配置优化

简介

neovim是从vim的一个分支fork出来的，从性能等方面来讲都比vim强很多，所以从vim转到neovim了。

本文涉及的neovim配置都在https://git.zeekling.cn/linux/nvim-config/src/branch/master里面。

快速使用方法：

代码语言：javascript复制
git clone https://git.zeekling.cn/linux/nvim-config.git ~/.config/nvim
# 或者
git clone ssh://git@git.zeekling.cn:222/linux/nvim-config.git ~/.config/nvim

打开nvim就可以自动安装插件了。

从0开始配置

初始化插件管理器

init.lua为neovim的默认配置，一般在~/.config/nvim下面。在文件里面写如下面内容，关键的一行为：require("lazynvim-init")，表示需要加载插件lazynvim-init，用于初始化lazy插件管理器。

代码语言：javascript复制
vim.g.mapleader = " "
vim.o.background = "light"
local vim = vim

require("lazynvim-init")

在新建~/.config/nvim/lua/lazynvim-init.lua文件，写入下面内容，核心内容是初始化lazy插件管理器。require("lazy").setup("plugins")主要是保证lazy插件加载~/.config/nvim/lua/plugins 下面的lua文件作为插件的配置。

代码语言：javascript复制
vim.wo.number = true
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",
		"git@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("plugins")

插件配置

必选插件

~/.config/nvim/lua/plugins/plugin-base.lua文件里面配置了个人认为必选的插件。

代码语言：javascript复制
return {
  {
    "nathom/filetype.nvim",
    lazy = true,
    event = "User FileOpened",
    config = function()
        require("filetype").setup({
            overrides = {
                extensions = {
                    h = "cpp",
                },
            }
        })
    end
  },
  {
    "HiPhish/nvim-ts-rainbow2",
    -- Bracket pair rainbow colorize
    lazy = true,
    event = { "User FileOpened" },
  },
  {
    "romgrk/nvim-treesitter-context",
    lazy = true,
    event = { "User FileOpened" },
    config = function()
        require("treesitter-context").setup({
            enable = true,
            throttle = true,
            max_lines = 0,
            patterns = {
                default = {
                    "class",
                    "function",
                    "method",
                },
            },
        })
    end,
  },
  {
    "windwp/nvim-spectre",
    lazy = true,
    cmd = { "Spectre" },
    config = function()
        require("spectre").setup()
    end,
  },

    -- Highlight, jump between pairs like if..else
    lazy = true,
    event = { "User FileOpened" },
    config = function()
        vim.g.matchup_matchparen_offscreen = { method = "popup" }
        lvim.builtin.treesitter.matchup.enable = true
    end,
  },
  {
    "rcarriga/nvim-notify",
    lazy = true,
    event = "VeryLazy",
    config = function()
        local notify = require("notify")
        notify.setup({
            -- "fade", "slide", "fade_in_slide_out", "static"
            stages = "static",
            on_open = nil,
            on_close = nil,
            timeout = 3000,
            fps = 1,
            render = "default",
            background_colour = "Normal",
            max_width = math.floor(vim.api.nvim_win_get_width(0) / 2),
            max_height = math.floor(vim.api.nvim_win_get_height(0) / 4),
            -- minimum_width = 50,
            -- ERROR > WARN > INFO > DEBUG > TRACE
            level = "TRACE",
        })

        vim.notify = notify
    end,
  },
  {

                },
            },
            presets = {
                bottom_search = false,
                command_palette = true,
                long_message_to_split = true,

                view_search = "virtualtext",
            },
            health = {
                checker = false,
            },

    branch = "v3.x",
    dependencies = {

      "MunifTanjim/nui.nvim",
      -- "3rd/image.nvim", -- Optional image support in preview window: See `# Preview Mode` for more information
    }
  },
  {

  },
  {
    "azabiong/vim-highlighter",
  },
  {"stevearc/dressing.nvim", opts = {}}

}

Markdown

个人使用Markdown比较多，所以配置了Markdown的插件，在~/.config/nvim/lua/plugins/markdown.lua文件里面配置下面：

代码语言：javascript复制
return {
    "iamcco/markdown-preview.nvim",
    cmd = { "MarkdownPreviewToggle", "MarkdownPreview", "MarkdownPreviewStop" },
    ft = { "markdown" },
    build = function()
        vim.fn["mkdp#util#install"]()
    end,
    lazy = true;
}

自动补全

在~/.config/nvim/lua/plugins/auto-complete.lua文件里面配置了自动补全的配置：

代码语言：javascript复制
return {
      {
        "hrsh7th/nvim-cmp",
        dependencies = {
            "hrsh7th/cmp-buffer",
            "hrsh7th/cmp-path",
            "hrsh7th/cmp-nvim-lsp",
            "L3MON4D3/LuaSnip",
            "saadparwaiz1/cmp_luasnip",
        },
        config = function()
            local cmp = require("cmp")
 
            cmp.setup({
                snippet = {
                    expand = function(args)
                        require("luasnip").lsp_expand(args.body)
                    end,
                },
                mapping = cmp.mapping.preset.insert({
                    ['<C-b>'] = cmp.mapping.scroll_docs(-4),
                    ['<C-f>'] = cmp.mapping.scroll_docs(4),
                    ['<C-Space>'] = cmp.mapping.complete(),
                    ['<C-e>'] = cmp.mapping.abort(),
                    ['<CR>'] = cmp.mapping.confirm({ select = true }),
                }),
                sources = cmp.config.sources({
                    { name = 'nvim_lsp' },
                    { name = 'luasnip' },
                }, {
                    { name = 'buffer' },
                    { name = "path" },
                }),
            })
        end,
    }, 
    {
      "neovim/nvim-lspconfig"
    }
}

快捷键以及提示

当插件过多之后，发现快捷键记不住，所以插件folke/which-key.nvim很有必要。配置如下:

代码语言：javascript复制
return {
    {
        "folke/which-key.nvim",
        config = function()
            vim.o.timeout = true
            vim.o.timeoutlen = 300
 
            local wk = require("which-key")
            -- 快捷键在这里定义
	    wk.register({
               ["<leader>"] = {
	          b = {
                    name="Buffer",
	              p={"<cmd>BufferLineCyclePrev<cr>", "Go to pre buffer"},
	              n={"<cmd>BufferLineCycleNext<cr>", "Go to next buffer"},
	              d={"<cmd>bd<cr>", "delete current buffer"}
	          },
                 d = {
                   name="dirTree",
                   s={"<cmd>NvimTreeToggle<cr>", "show dir tree on left"},
                   c={"<cmd>NvimTreeClose<cr>", "hidden dir tree on left"}
	        },
	         m = {
                   name="Markdown",
	              k={
                        name="Markdown",
		        s={"<cmd>MarkdownPreview<cr>", "MarkdownPreview"},
		        c={"<cmd>MarkdownPreviewStop<cr>", "MarkdownPreviewStop"}
	              }
	         },
		 s = {
                   name="Search"
		 }
           }
        }, {silent = true, noremap = true})
        wk.setup()
        end,
    },
}
