## lint

Lint files for non-standard or incorrect documentation
information, returning a potentially-empty string
of lint information intended for human-readable output.

**Parameters**

-   `indexes` **([Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)> | [string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String))** files to process
-   `args` **[Object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object)** args
    -   `args.external` **[Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)>** a string regex / glob match pattern
        that defines what external modules will be whitelisted and included in the
        generated documentation.
    -   `args.polyglot` **[boolean](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** parse comments with a regex rather than
        a proper parser. This enables support of non-JavaScript languages but
        reduces documentation's ability to infer structure of code. (optional, default `false`)
    -   `args.shallow` **[boolean](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** whether to avoid dependency parsing
        even in JavaScript code. With the polyglot option set, this has no effect. (optional, default `false`)
    -   `args.inferPrivate` **[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)?** a valid regular expression string
        to infer whether a code element should be private, given its naming structure.
        For instance, you can specify `inferPrivate: '^_'` to automatically treat
        methods named like `_myMethod` as private.
    -   `args.extension` **([string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) \| [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)&lt;[string](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String)>)?** treat additional file extensions
        as JavaScript, extending the default set of `js`, `es6`, and `jsx`.

**Examples**

```javascript
documentation.lint('file.js').then(lintOutput => {
  if (lintOutput) {
    console.log(lintOutput);
    process.exit(1);
  } else {
    process.exit(0);
  }
});
```

Returns **[Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise)** promise with lint results
