Options

Property	Type	Required	Description
message	string	yes	The question to ask
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.
file	IFileOptions	no	Exposes the external-editor package options to configure the temporary file.
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.
theme	See Theming	no	Customize look of the prompt.

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.

type Theme = {
  prefix: string | { idle: string; done: string };
  spinner: {
    interval: number;
    frames: string[];
  };
  style: {
    message: (text: string, status: 'idle' | 'done' | 'loading') => string;
    error: (text: string) => string;
    help: (text: string) => string;
    key: (text: string) => string;
  };
  validationFailureMode: 'keep' | 'clear';
};

validationFailureMode defines the behavior of the prompt when the value submitted is invalid. By default, we'll keep the value allowing the user to edit it. When the theme option is set to clear, we'll remove and reset to the default value or empty string.
