操作系统:Ubuntu20.40。

安装coc

安装Node.js

• 安装命令：curl -sL install-node.now.sh | bash
• npm安装neovim和yarn：sudo npm i --registry https://registry.npm.taobao.org install -g neovim yarn
• 配置淘宝镜像：npm config set registry https://registry.npm.taobao.org

vim-plug安装coc.nvim

• 在Vim默认配置文件或Neovim默认配置文件中添加：Plug 'neoclide/coc.nvim', {'branch': 'release'}
• 先保存文件，比如vim用:w
• vim命令模式加载配置文件：:source %
• 安装插件:PlugInstall
• 检查coc.nvim服务状态：:checkhealth

coc常用命令

• 查看安装了那些子插件：:CocList extensions。可采用模糊搜索方法选中安装的插件，之后按Tab对插件进行处理。
• 命令模式安装插件的命令：:CocInstall
• 打开配置文件命令：:CocConfig

安装coc扩展

• 安装coc.nvim子插件商城：:CocInstall coc-marketplace
• 安装markdown子插件：
  • 使用:coc-marketplace查询插件：:CocList marketplace markdown
  • 安装coc-markdownlint：:CocInstall coc-markdownlint
• 通过coc.nvim提供的更方便的方式安装插件(推荐)
  • 在vim(neovim)配置文件里面设置变量：g:coc_global_extensions。
  • 比如添加如下设置，再次进入vim时，就会自动安装列表里面的子插件。

   let g:coc_global_extensions = [
  		\ 'coc-marketplace',
  		\ 'coc-json',
  		\ 'coc-vimlsp',
  		\ 'coc-markdownlint',
  		\ 'coc-sh',
  		\ 'coc-pyright',
  		\ 'coc-yaml',
  		\ 'coc-tabnine',
  		\ 'coc-translator',
  		\ 'coc-snippets',
  		\ 'coc-java',
  		\ 'coc-java-intellicode',
  		\ 'coc-xml',
  		\]

• 如果java遇到Error: The "java" server crashed xxx times in the last xxx minutes. The server will not be restarted错误时，参看coc-java的github上面提到的解决方法jdk版本与jdt语言服务器版本适配问题。
