Inquirer Checkbox Plus Prompt

A plugin for Inquirer, similar to the original checkbox with extra features.

Installation

npm install -g inquirer-checkbox-plus-prompt

Usage

You can name it with any name other than checkbox-plus, just change the string 'checkbox-plus' to anything else.

inquirer.registerPrompt('checkbox-plus', require('inquirer-checkbox-plus-prompt'));
 
inquirer.prompt({
  type: 'checkbox-plus',
  ...
})

Options

Takes type, name, message, source[, filter, validate, default, pageSize, highlight, searchable] properties.

The extra options that this plugin provides are:

• source: (Function) a method that called to return a promise that should be resolved with a list of choices in a similar format as the choices option in the original checkbox prompt of Inquirer.
• highlight: (Boolean) if true, the current selected choice gets highlighted. Default: false.
• searchable: (Boolean) if true, allow the user to filter the list. The source function gets called everytime the search query is changed. Default: false.
