## Config

**NOTE**: If you want to support linter that do not include by default,
you should read the [README](https://github.com/iamcco/diagnostic-languageserver#how-to-config-a-new-linter)
for how to config a new linter.

> `linters` `filetypes` `formatters` `formatFiletypes` field config are same as diagnostic-languageserver.
> this extension include all linters config at [linters](https://github.com/iamcco/diagnostic-languageserver/wiki/Linters)
> therefor if you use the linter which have included then you don't need to config linters and formatters

If `mergeConfig` is `true` (default `false`) then any configuration for
`linters` and `formatters` is merged with [the default
configuration](./src/config.ts), this allow overriding specific parts of the
configuration only.

**To enable this plugin for filetypes** you have to config `diagnostic-languageserver.filetypes`
for linters and `diagnostic-languageserver.formatFiletypes` for formatters.

example coc-settings.json:

``` jsonc
{
  // diagnostic-languageserver
  "diagnostic-languageserver.filetypes": {
    "vim": "vint",
    "email": "languagetool",
    "markdown": [ "write-good", "markdownlint" ],
