Very useful feature, would love to see this merged! In the meantime Im using this little workaround:

const { AutoComplete } = require('enquirer');

export class AutoSuggest extends AutoComplete {
  constructor(options) {
    super(options);
  }

  suggest(input = this.input, choices = this.state._choices) {
    if (typeof this.options.suggest === 'function') {
      return this.options.suggest.call(this, input, choices);
    }

    let str = input.toLowerCase();

    const filtered = choices.filter((ch) => !ch._userInput).filter((ch) => ch.message.toLowerCase().includes(str));

    if (!filtered.length && this.options.inputNoChoice) {
      filtered.push({ name: input, message: input, value: input, _userInput: true });
    }

    return filtered;
  }
}

I agree that this should be allowed. But I need to think about this approach.

For now, you can do this:

const { AutoComplete } = require('enquirer');

const fakeChoice = input => ({ value: input, message: '', name: input });

const prompt = new AutoComplete({
  type: 'autocomplete',
  name: 'flavor',
  message: 'Pick your favorite flavor',
  suggest(typed, choices) {
    const maches = choices.filter(choice => choice.message.includes(typed));
    return maches.length ? maches : [fakeChoice(typed)];
  },
  choices: [
    'almond',
    'apple',
    'banana'
  ]
});

prompt.run()
  .then(output => console.log({ output }))
  .catch(console.log);

IMHO this might be a better option anyway, since it doesn't complicate the lib further and demonstrates that you can do anything you need to with custom code already. Thoughts?
