let g:defx_icons_column_length = 2

### nvim-lsp-installer打造 python IDE

#### 安装

```shell
use 'kabouzeid/nvim-lspinstall'
```

#### 配置

```shell
nvim ~/.config/nvim/after/plugin/nvim-lspinstall.lua

require'lspinstall'.setup() -- important

local servers = require'lspinstall'.installed_servers()
for _, server in pairs(servers) do
  require'lspconfig'[server].setup{}
end

```

#### 使用方式

- LspInstall <language> to install/update the language server for <language> (e.g. :LspInstall python).
- LspUninstall <language> to uninstall the language server for <language>.
- require'lspinstall'.setup() to make configs of installed servers available for require’lspconfig’.<server>.setup{}.
- :LspInstall python
