Git-style interactive list selector for Node CLI apps

• Does one thing: Lets the users of your NodeJS app interactively select/de-select items from a list by indices and ranges on the commandline.

• Familiar "UI" -- to GitHubbers at least! Same interface as the trusty "git add --interactive"

• Brain-dead simple to use in your project

• Options can be any array of toString-able things

• Get the user's response in a callback OR a jQuery-style promise

Example: Let's make a sandwich

Probably better for selecting filepaths, but I'm hungry right now so...

Let's choose the toppings on your sandwich via CLI.

What you do

0. Install from NPM:

npm install list-selector-cli`

1. Require it in your project:

var cliselect = require("list-selector-cli");

2. Pick an array of options:

var options = ["lettuce", "tomatoes", "spinach", "ham"];

3. Create your list:

var sandwichChoice = new cliselect(options);

4. Prompt the user: console.log("What would you like on your sandwich?")

5. Let them interactively choose their options and handle their response

• In a callback:

sandwichChoice.prompt(function(selection) { /** do something **/ });

• Or with a promise:

var promise = sandwichChoice.prompt();
promise.done(function(selection) { /** do something **/ });

What you get

$ node examples/sandwich.js

What would you like on your sandwich?

Totally pitching a commandline interface to Subway...

Maybe ssh.subway.com: "open 8am to 9pm and 24 hrs a day on port 22..." :-)
