==========

A tiny CLI prompter

[![build status](https://secure.travis-ci.org/carlos8f/node-cli-prompt.png)](http://travis-ci.org/carlos8f/node-cli-prompt)

Install
-------

```javascript
$ npm install --save cli-prompt
```

Usage
-----

### `prompt(message, onValue, [onError])`

- `message`: text prompt for the user
- `onValue`: function to be called (after user hits enter/return) with the entered text
- `onError`: optional function to receive an error, if STDIN has already ended, for example.

Note: cli-prompt will not work if STDIN has ended. If provided, onError will be called in this case.

Example
-------

```js
var prompt = require('cli-prompt');

prompt('enter your first name: ', function (val) {
  var first = val;
  prompt('and your last name: ', function (val) {
    console.log('hi, ' + first + ' ' + val + '!');
  }, function (err) {
    console.error('unable to read last name: ' + err);
  });
}, function (err) {
  console.error('unable to read first name: ' + err);
});
```

### Password/hidden input

```js
var prompt = require('cli-prompt');

prompt.password('tell me a secret: ', console.log, console.error);
```

### Multiple questions

```js
var prompt = require('cli-prompt');

prompt.multi([
  {
    key: 'username',
    default: 'john_doe'
  },
  {
    label: 'password (must be at least 5 characters)',
    key: 'password',
    type: 'password',
    validate: function (val) {
      if (val.length < 5) throw new Error('password must be at least 5 characters long');
    }
  },
  {
    label: 'number of pets',
    key: 'pets',
    type: 'number',
    default: function () {
      return this.password.length;
    }
  },
  {
    label: 'is this ok?',
    type: 'boolean'
  }
], console.log, console.error);
```
