Usage

Tool

For simple styles, the class Matks\Vivian\Tools provide a useful call interface, for example:

use Matks\Vivian\Tools as Output;

echo Output::bold('... done.') . PHP_EOL;

if ($success) {
	echo Output::green('Success');
	echo PHP_EOL;
} else {
	echo Output::red('Failure !');
	echo PHP_EOL;
	echo Output::s_list1($errors);
}

or

bash tests/Console/test-all.sh

Elements

For advanced displays, build the Elements you need:

Text Element

use Matks\Vivian\Color;
use Matks\Vivian\Style;
use Matks\Vivian\Output;

$textElement = new Output\TextElement('Hello world !');

$boldStyle             = new Style\Style(Style\StyleManager::BASH_BOLD);
$greenColor            = new Color\TextColor(Color\TextColorManager::BASH_FOREGROUND_GREEN);
$cyanBackgroundColor   = new Color\BackgroundColor(Color\BackgroundColorManager::BASH_BACKGROUND_CYAN);

$textElement->setTextColor($greenColor)
            ->setBackgroundColor($cyanBackgroundColor)
            ->addStyle($boldStyle)
;

echo $textElement->render();

Bordered Element

use Matks\Vivian\Border;
use Matks\Vivian\Color;
use Matks\Vivian\Output;

$yellowColor = new Color\TextColor(Color\TextColorManager::BASH_FOREGROUND_YELLOW);
$border      = new Border\Border(Border\Border::TYPE_FRAME);

$borderedElement = new Output\BorderedElement('Hello world !', $border);
$borderedElement->setTextColor($yellowColor);

echo $borderedElement->render();

Structured Elements

use Matks\Vivian\Color;
use Matks\Vivian\Output;
use Matks\Vivian\Style;
use Matks\Vivian\Structure;

$greenColor     = new Color\TextColor(Color\TextColorManager::BASH_FOREGROUND_GREEN);
$redColor       = new Color\TextColor(Color\TextColorManager::BASH_FOREGROUND_RED);
$blinkingStyle  = new Style\Style(Style\StyleManager::BASH_BLINK);

$textElement1 = new Output\TextElement('Hello');
$textElement2 = new Output\TextElement('world');
$textElement3 = new Output\TextElement('!');
$textElement1->setTextColor($greenColor);
$textElement2->setTextColor($redColor);
$textElement3->addStyle($blinkingStyle);

$elements = array(
    $textElement1,
    $textElement2,
    $textElement3
);

$structure  = new Structure\Structure(Structure\Structure::TYPE_LIST, '#', '  ');
$structuredElements = new Output\StructuredElements($elements, $structure);
echo $structuredElements->render();

More advanced features

I found a far more efficient library doing the same purpose: CLImate. I recommend it.
