List

The List prompt is a text input that lets you input multiple values with support for auto suggestions.

Options

The List prompt implements all base and auto suggestion options and the following prompt specific options.

Tag separator

With the separator option you specify the delimiter that is used for separating the tags. Default is ,.

Min input length

The minLength option specifies the minimum length of a tag. Default is 0.

Max input length

The maxLength option specifies the maximum length of a tag. Default is infinity.

Min tags

The minTags option specifies the minimum amount of tags. Default is 0.

Max tags

The maxTags option specifies the maximum amount of tags. Default is infinity.

List pointer

With the listPointer you specify the list pointer icon. Default is ❯.

Display usage info

The info option enables the info bar which displays some usage information.

Auto suggestions

Tab-completions can be enabled with the suggestions and/or id option. If an id is provided, the value will be saved to the local storage using the id as local storage key. With suggestions you can provide some default suggestions. Both options can be defined at the same time. You can read more about auto suggestions here.

❕ The id option requires deno >= 1.10 and the --location flag. Since deno 1.16.0 the --location flag is optional.

import { List } from "https://deno.land/x/cliffy@v0.24.2/prompt/list.ts";

const color: string = await List.prompt({
  message: "Choose a color",
  id: "<local-storage-key>",
  suggestions: [
