<?php

use pointybeard\Helpers\Cli\Prompt\Prompt;
use pointybeard\Helpers\Cli\Message\Message;
use pointybeard\Helpers\Cli\Colour\Colour;

// The most basic of prompt
$name = (new Prompt("Enter your name"))->display();
// Enter your name:

// Prompt with a default value
$proceed = (new Prompt("Proceed with installation?"))
    ->default('yes')
    ->display()
;
// Proceed with installation? [yes]:

// A prompt that does not echo the value as it is typed
$password = (new Prompt)
    ->prompt("Enter password")
    ->flags(Prompt::FLAG_SILENT)
    ->display()
;

// Prompt with a custom Cli/Message/Message object instead of a string
$value = (new Prompt)
    ->prompt((new Message)
        ->message("Some fancy looking prompt")
        ->foreground(Colour::FG_BLACK)
        ->background(Colour::BG_YELLOW)
        ->flags(NULL)
    )
    ->display()
;

// Validate the input
$emailAddress = (new Prompt("Enter Email Address"))
    ->validator(function($input) {
        if(strlen(trim($input)) <= 0) {
            (new Message)
                ->message("Email address is required!")

                ->message("Email address is invalid!")
                ->foreground(Colour::FG_WHITE)
                ->background(Colour::BG_RED)
                ->display()
