prompts #

Rich, simple, synchronous command-line prompt library for Dart.
Now with pretty colors!

Example #
import 'package:io/ansi.dart';
import 'package:prompts/prompts.dart' as prompts;

void main() {
// Easily get a single line.
var name = prompts.get('Enter your name');
print('Hello, $name!');

// ... Or many lines.
print('Tell me about yourself.');
var bio = prompts.get(
"Enter some lines, using '\\' to escape line breaks",
allowMultiline: true,
inputColor: resetAll,
);
print('About $name:\n$bio');

// Supports default values.
name = prompts.get('Enter your REAL name', defaultsTo: name);
print('Hello, $name!');

// "High-level" prompts are built upon [get].
// For example, we can prompt for confirmation trivially.
bool shouldDownload = prompts.getBool('Really download this package?');

if (!shouldDownload)
print('Not downloading.');
else
print('Downloading...!');

// Or, get an integer, WITH validation.
int age = prompts.getInt('How old are you?', defaultsTo: 23, chevron: false);
print('$name, you\'re $age? Cool!');

// We can choose from various values.
// There are two methods - shorthand and regular.
var rgb = [Color.red, Color.green, Color.blue];
Color color = prompts.chooseShorthand('Tell me your favorite color', rgb);
print('You chose: ${color.about}');

// The standard chooser prints to multiple lines, but is often
// clearer to read, and has more obvious semantics.
color = prompts.choose('Choose another color', rgb, defaultsTo: Color.blue);
print(color.about);
}

class Color {
final String name, description;

const Color(this.name, this.description);

static const Color red = const Color('Red', 'The color of apples.'),
blue = const Color('Blue', 'The color of the sky.'),
green = const Color('Green', 'The color of leaves.');

String get about => '$name - $description';

@override
String toString() => name;
}
