inquirer-checkbox-status

Checkbox prompt for inquirer with live custom status info about current selection. I had a really hard time using BottomBar for this usage with standard checkbox prompt so I extended it to re-use the live bottom space used to display validation errors.

Installation

npm install --save inquirer-checkbox-status

Usage

This prompt is fully compatible with checkbox, so you can overwrite it with this prompt, or use any other name that's up to you.

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

Options

All options expected by checkbox core prompt are expected too and will have same effect, as checkbox-status just extends it. A new option can be specified:

status

status is a function called on initial rendering, and each time a choice is toggled. It must return a string. Whenever it returns a non-empty string, this result will be used to display a status message at bottom. If an error was meant to be displayed, your status will be hidden.

Example

inquirer.registerPrompt('checkbox', require('./index'))
inquirer.prompt([{
  type: 'checkbox',
  status: function (choices) {
    return 'Total = ' + _.sum(_.map(choices.where({ checked: true }), 'value'))
  },
  name: 'addition',
  message: 'select numbers',
  choices: [
    { name: 'one',   short: '1', value: 1, checked: true },
    { name: 'two',   short: '2', value: 2, checked: false },
    { name: 'three', short: '3', value: 3, checked: false },
    { name: 'four',  short: '4', value: 4, checked: true },
  ]
}])
