lsp client config example with coc.nvim

- Using node ipc

```jsonc
"languageserver": {
  "vimls": {
    "module": "/path/to/vim-language-server/bin/index.js",
    "args": ["--node-ipc"],
    "initializationOptions": {
      "isNeovim": true, // is neovim, default false
      "iskeyword": "@,48-57,_,192-255,-#", // vim iskeyword option
      "vimruntime": "", // $VIMRUNTIME option
      "runtimepath": "",   // vim runtime path separate by `,`
      "diagnostic": {
        "enable": true
      },
      "indexes": {
        "runtimepath": true,      // if index runtimepath's vim files this will effect the suggest
        "gap": 100,               // index time gap between next file
        "count": 3,               // count of files index at the same time
        "projectRootPatterns" : ["strange-root-pattern", ".git", "autoload", "plugin"] // Names of files used as the mark of project root. If empty, the default value [".git", "autoload", "plugin"] will be used
      },
      "suggest": {
        "fromVimruntime": true,   // completionItems from vimruntime's vim files
        "fromRuntimepath": false  // completionItems from runtimepath's vim files, if this is true that fromVimruntime is true
      }
    },
    "filetypes": [ "vim" ],
  }
}
```

- Using stdio

```jsonc
"languageserver": {
  "vimls": {
    "command": "vim-language-server",
    "args": ["--stdio"],
    "initializationOptions": {
      "isNeovim": true, // is neovim, default false
      "iskeyword": "@,48-57,_,192-255,-#", // vim iskeyword option
      "vimruntime": "",                    // $VIMRUNTIME option
      "runtimepath": "",                   // vim runtime path separate by `,`
      "diagnostic": {
        "enable": true
      },
      "indexes": {
        "runtimepath": true,      // if index runtimepath's vim files this will effect the suggest
        "gap": 100,               // index time gap between next file
        "count": 3,               // count of files index at the same time
        "projectRootPatterns" : ["strange-root-pattern", ".git", "autoload", "plugin"] // Names of files used as the mark of project root. If empty, the default value [".git", "autoload", "plugin"] will be used
      },
      "suggest": {
        "fromVimruntime": true,   // completionItems from vimruntime's vim files
        "fromRuntimepath": false  // completionItems from runtimepath's vim files, if this is true that fromVimruntime is true
      }
    },
    "filetypes": [ "vim" ]
  }
}
```

**Note**:

- if you set `isNeovim: true`, command like `fixdel` in vimrc which neovim does not support will report error.
- if you want to speed up index, change `gap` to smaller and `count` to greater, this will cause high CPU usage for some time
- if you don't want to index vim's runtimepath files, set `runtimepath` to `false` and you will not get any suggest from those files.

## Usage
