| default         | `string`                                                    | no                     | Default value which will automatically be present in the editor                                                                                                                                                                        |
| validate        | `string => boolean \| string \| Promise<boolean \| string>` | no                     | On submit, validate the content. When returning a string, it'll be used as the error message displayed to the user. Note: returning a rejected promise, we'll assume a code error happened and crash.                                  |
| postfix         | `string`                                                    | no (default to `.txt`) | The postfix of the file being edited. Adding this will add color highlighting to the file content in most editors.                                                                                                                     |
| waitForUseInput | `boolean`                                                   | no (default to `true`) | Open the editor automatically without waiting for the user to press enter. Note that this mean the user will not see the question! So make sure you have a default value that provide guidance if it's unclear what input is expected. |

## Theming

You can theme a prompt by passing a `theme` object option. The theme object only need to includes the keys you wish to modify, we'll fallback on the defaults for the rest.

```ts
type Theme = {
  prefix: string;
  spinner: {
    interval: number;
    frames: string[];
  };
  style: {
    message: (text: string) => string;
    error: (text: string) => string;
    help: (text: string) => string;
    key: (text: string) => string;
  };
};
```
