neovim在linux下配置

neovim配置文件夹

一个现代化成品neovim

mkdir  ~/.config/nvim
nvim ~/.config/nvim/init.vim

其余配置类似vim。

neovim在linux下的配置:

• 建议首先将linux内核版本更新,不然很多插件版本不够.
• vim在linux下配置依靠/etc/vim目录中的vimrc,命令是:

sudo nvim ~/config/nvim/init.vim

• 这种配置是在根目录下的进入方式,另外一种方式是在home文件中的个人账户中进行配置,这种配置方式会覆盖之前的配置文件.

cd ~                       //进入home/xxxx/目录
nvim ~/config/nvim/init.vim       //创建配置文件

vim-plug配置

==vim-plug是一个安装管理器,用来管理vim中的插件安装.==相较于vundle,它现在是仍然维护的.

• vim-plug安装地址,根据提示选择vim linux的即可.
• 使用vimplug配置管理vim,但同时需要安装git和curl,安装的命令是:

sudo apt-get install git
sudo apt-get install curl

• 安装完成之后,可以进入配置文件:

nvim ~/.config/nvim/init.vim

• 在末尾添加:

call plug#begin()
call plug#end()

• 然后将需要的插件放入这两个中间即可.
• 它的安装命令是在vim命令行中输入PlugInstall.

插件安装网站

• 插件的安装在vimawesome之中,直接打开网址搜索需要的插件,在插件中选择vim-plug进行安装,将插件放入上段代码之中即可，（先进行保存退出之后再进行安装）至于安装的命令,是使用PlugInstall,这个在vimplug里面有相关的说明.

安装coc.nvim

• 相较于令人头疼的youcompleteme，更好用的插件显然是coc.nvim
  nvim懒人配置
• 使用coc.nvim
• 使用配置

---

coc.nvim配置

coc.nvim的基本命令

• :CocInstall **
• :CocUninstall **

---

Coc扩展安装：

:CocInstall coc-json

---

Coc现存扩展

• :CocList extensions
• 在这个命令之中可以使用<“Tab”>来查看其他内敛命令
• *代表插件已经启用，+号代表插件存在但是未启动

CocCommand

• coc本身插件的指令

Coc扩展商店

:CocList marketplace

• 使用jk或者上下来进行勾选。直接输入关键字来进行搜索。然后使用回车进行安装

Coc扩展帮助

:h 插件名称

• 查看是否有某函数

:echo exists('*complete_info')

---

通过在neovim中init.vim预留位置来配置coc.nvim

• 对照官方文档，在nvim中使用下面的一些配置,不要直接复制粘贴

"设置缓存，因为vim不允许在保存之前进行跳转，所以设置缓存之后，coc可以帮助你跳转函数声明等。
set hidden
"设置响应时间，让vim更快
set updatetime=100
"设置行号共用
set signcolumn=number
"设置少输出无用信息
set shortmess+=c

"设置tab键补全和shift——tab进行关闭terminal
inoremap <silent><expr> <TAB>
      \ pumvisible() ? "\<C-n>" :
      \ <SID>check_back_space() ? "\TAB" :
      \ coc#refresh()
inoremap <expr><S-TAB> pumvisible() ? "\<C-p>" : "\<C-h>"

function! s:check_back_space() abort
	let col = col('.') - 1
	return !col || getline('.')[col - 1] =~# '\s'
endfunction
"设置ctrl+o调出补全
inoremap <silent><expr> <c-o> coc#refresh()

---

coc-settings.json配置coc自己的参数

• 作用和coc插件类似，打开方式：

The user configuration is named as coc-settings.json and placed inside
the folder $XDG_CONFIG_HOME/nvim or $HOME/.config/nvim by default (or
$HOME/.vim for vim). Run the command :CocConfig to open your user
configuration file.

• 即打开方式为：

nvim ~/.config/nvim/coc-setting.json

• 或者

:CocConfig

• 在这个文件夹中配置了自动更新每天检查，回车补全扩展

{
  "clangd.path": "~/.config/coc/extensions/coc-clangd-data/install/15.0.3/clangd_15.0.3/bin/clangd",
  "coc.preferences.extensionUpdateCheck":"daily",
  "suggest.noselect": true,
  "suggest.enablePreselect":false
}

---

获得进度完成插件

• 安装vim-dart(平台优化开发框架)
• 安装coc-flutter,安装了也用不上。

---

coc-snippets可以添加自定义的补全

---

大佬的讲解

---

• 最后的结果是：ctrl+l显示tab补全，回车进行补全，检查错误使用的是[g和]g,使用gd进行关键字搜索，\h进行相关文档介绍。，重命名函数使用关键字\r。
• 最后是重新安装了NerdTree，使用的快捷键是F4
• 目前的配置
