Inquirer.js

Fixes

• Fix bug where inquirer would overwrite properties on the options passed in. Now we're making sure to not mutate your originals objects.
• On the checkbox prompt, we're now only hiding the help message once the user click the space key instead of any keys.
• Drop readline2 in favor of Node core version. This might fix some edge cases some users on windows encountered.

Say hello to promises!

The whole inquirer API is now based on promises!

• The base API interface is now inquirer.prompt(questions).then(). There's no more callback function.
• Any async question functions is taking a promise as return value instead of requiring this.async().

Breaking changes

• filter is now always run before validate #122
• inquirer.prompt doesn't take a callback argument anymore

Bug fixes

• Fixed list not displayed disabled options correctly #321

And various other minor fixes and cleanup to the code base.

• List prompts can now be navigated using Emacs bindings
• expand prompt now use the short question property to display inline after a choice is selected
• Bump and internal cleanup

• Fix error on environment where cli-width return 0 (we're now defaulting to 80 chars width)

• Fix bug with astral symbols not being calculated correctly in the width of a line
• expand prompt now trim the whitespace around the answer

• Some display fixes on Windows (mainly) and Unix system.
• Internal refactoring of the rendering logic.

Fix list overflow bug when the list contains separators.

• Choices object now take an optional short property that'll be use in the prompt summary after a user selected choice.
• Fix bug if using a terminal without defined width (we're now defaulting to 80 chars in that case)

• Fix the bottom bar functionality
• Minor code cleanup

New feature

• inquirer.createPromptModule(opt) not take an option arguments. These options will be passed to the readline factory.

Bug fix

• Fix #276 and #209: adding a new observer to the process won't duplicate the prompts (basically the prompt processing queue is now a hot observable).

Fix issue with cursor position in the input prompt.

This is not a huge release feature wise. It's been mostly a huge internal refactoring of our rendering system. This is all done with the hope of moving towards a 1.0 release where we'll have a stronger Prompt API allowing the creation of custom prompts.

In the meantime, included in 0.9:

1. Fix a lot of issues with natural line returns messing inquirer.js prompt re-rendering.
2. The validate function now takes the list of current answers as arguments. #198

• More consistent handling of the checkboxes checked param if the value is truthy (before the option would be checked but not selected) - #242

• when prompt option can now simply be a boolean value (before it needed to be a function).

• Revert usage of ttys module that was breaking Windows or non ttys terminals.

This release is really just a fix for version 0.8.1.

• use ttys module for a more reliable stdout.
• Remove/cleanup some dependencies for faster load time.

New Feature

Add inquirer.createPromptModule() who return a self contained inquirer.prompt method. This allow to decouple multiple interfaces who could rely on inquirer.prompt and different sets of prompts.

Example usage:

var prompt = inquirer.createPromptModule();

prompt.registerPrompt('long-list', LongListPrompt);

prompt([{
  type: 'long-list',
  message: 'Choose a menu item',
  choices: [ /* etc */ ]
}], callback);

Bug fix

• Correctly detect when to add a : to the end of a question phrase if it the question contains color codes.

Bug

• Update checkbox icons (some people had issue with their terminal fonts)

Feature

• message can now also be a function

• Fix bug with checkbox prompt validation
