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）
| 快捷键 | 功能 |
|---|---|
| <leader>j | next buffer |
| <leader>k | previous buffer |
| <leader>[number] | to buffer [number] |
| <space>bc | close invisible buffers |
| <space>bd | close current buffer |
| <space>bt | close other buffers |
4 nvim-treesitter
- 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>',
}
},- 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',
},
},- 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：

| <leader>o | search symbols in current file |
| <leader>s | search symbols in project |
| <leader>g | live grep, 内容搜索 |
