1 前言

本来SpaceVim用的好好的，在无意中一次更新Nvim和插件后，一切都改变了：各种乱七八糟的插件报错，怎么也解决不了，看来别人配好的东西还是有点局限性，真要稳定使用还得自己DIY，于是毅然删除了SpaceVim，从头开始配置我的Neovim（结合之前自己的vim配置）。这里记录一下几个常用插件的常用功能，作为备忘录使用，刚开始用的不熟时可以方便自己迅速找到参考处。

nvim查看某快捷键详细信息： :verbose map xxx<cr>

(各插件不分先后顺序)

2 nvim-tree

侧边栏，呼出的命令分NvimTreeToggle与NvimTreeFindFile两个，用which-key插件统一管理快捷键，开关的快捷键我设为了<Space>ft或<leader>n，定位到文件的快捷键我设为了<Space>fo或<space>n。前面的快捷键与原SpaceVim保持一致，后面的是我根据习惯设置的。其他快捷键配置见nvim-tree配置文件：

local keymap_list = {
  { key = { "<CR>", "o", "l", "<2-LeftMouse>" }, action = "edit" },
  { key = "h", action = "close_node" },
  { key = "p", action = "preview" },
  { key = "<C-r>", action = "refresh" },
  { key = "yn", action = "copy_name" },
  { key = "yp", action = "copy_path" },
  { key = "yy", action = "copy_absolute_path" },
  { key = "a", action = "create" },
  { key = "d", action = "remove" },
  { key = "r", action = "rename" },
  { key = "I", action = "toggle_git_ignored" },
  { key = "R", action = "collapse_all" },
  { key = "?", action = "toggle_help" },
}

3 buffer-line

自己设置的快捷键如下：（依赖close-buffers插件）

4 nvim-treesitter

1. 增量选择，可视模式下<CR>与<BS>进行选择；

  incremental_selection = { -- 启用增量选择
    enable = true,
    keymaps = {
      init_selection = '<CR>',
      node_incremental = '<CR>',
      node_decremental = '<BS>',
      scope_incremental = '<TAB>',
    }
  },

2. 智能选择，v.、v;、vi;分别对应smart、outer、inner三种模式；

textsubjects = { -- 智能选择
    enable = true,
    prev_selection = ',', -- (Optional) keymap to select the previous selection
    keymaps = {
      ['.'] = 'textsubjects-smart',
      [';'] = 'textsubjects-container-outer',
      ['i;'] = 'textsubjects-container-inner',
    },
  },

3. 文本对象的选择、跳转、交换等，新文本对象f(function)、c(class)；移动快捷键h为start、l为end、j为next、k为previous、小写为function、大写为class；

  textobjects = { -- 智能跳转
    select = {
      enable = true,

      -- Automatically jump forward to textobj, similar to targets.vim
      lookahead = true,

      keymaps = {
        -- You can use the capture groups defined in textobjects.scm
        ["af"] = "@function.outer",
        ["if"] = "@function.inner",
        ["ac"] = "@class.outer",
        -- you can optionally set descriptions to the mappings (used in the desc parameter of nvim_buf_set_keymap
        ["ic"] = { query = "@class.inner", desc = "Select inner part of a class region" },
      },
      -- You can choose the select mode (default is charwise 'v')
      selection_modes = {
        ['@parameter.outer'] = 'v', -- charwise
        ['@function.outer'] = 'V', -- linewise
        ['@class.outer'] = '<c-v>', -- blockwise
      },
      -- If you set this to `true` (default is `false`) then any textobject is
      -- extended to include preceding xor succeeding whitespace. Succeeding
      -- whitespace has priority in order to act similarly to eg the built-in
      -- `ap`.
      include_surrounding_whitespace = true,
    },
    move = {
      enable = true,
      set_jumps = true, -- whether to set jumps in the jumplist
      goto_next_start = {
        ["xl"] = "@function.outer",
        ["xL"] = "@class.outer",
      },
      goto_previous_start = {
        ["xh"] = "@function.outer",
        ["xH"] = "@class.outer",
      },
      goto_next_end = {
        ["xj"] = "@function.outer",
        ["xJ"] = "@class.outer",
      },
      goto_previous_end = {
        ["xk"] = "@function.outer",
        ["xK"] = "@class.outer",
      },
    },
  },

5 telescope

模糊搜索神器，有很多扩展，我装了fzf（模糊匹配）、bookmarks（书签,基于vim-bookmarks？）、heading、emoji、neoclip，此外还有个`telescope-coc，下面是我设置的快捷键位：

模糊匹配平时感觉用的挺多，这里先说下书签相关快捷键：

6 nvim-surround

Add/delete/change surrounding pairs

7 vista

显示symbols和tags导航栏，快捷键cn

8 vim-floaterm

9 vim-commentary

:Commentary注释代码，设定快捷键为<space>lc，默认快捷键如下：

10 undotree

显示编辑历史记录，:UndotreeToggle，设定快捷键<space>cu，打开后按?可查看更具体的帮助。

11 nvim-spectre

文件名替换，同时对多个文件进行替换。

12 code_runner

只用该插件的:RunCode命令，忽略其他功能，快捷键我设为<Space>rc

13 vim-table-mode

<space>tm进入/退出表格编辑模式

14 coc-nvim
