Memio's Twig templates, used to generate PHP code from given Model

v2.0.3 2018-03-02 15:17 UTC


Memio is a highly opinionated PHP code generator library. It is composed of small independent packages, one being PrettyPrinter: the actual code generator.

PrettyPrinter relies on an interface, TemplateEngine, but doesn't provide any implementation to avoid direct coupling to any templating libraries.

This package, TwigTemplateEngine, provides an implementation and templates for Twig.

Note: This package is part of Memio. Have a look at the main repository.


Install it using Composer:

composer require memio/twig-template-engine:^2.0


We're going to generate a class with a constructor and two attributes:


require __DIR__.'/vendor/autoload.php';

use Memio\Model\File;
use Memio\Model\Objekt;
use Memio\Model\Property;
use Memio\Model\Method;
use Memio\Model\Argument;

// Initialize the code generator
$loader = new \Twig\Loader\FilesystemLoader(__DIR__.'/templates');
$twig = new \Twig\Environment($loader);

$line = new Memio\TwigTemplateEngine\TwigExtension\Line\Line();
$line->add(new Memio\TwigTemplateEngine\TwigExtension\Line\ContractLineStrategy());
$line->add(new Memio\TwigTemplateEngine\TwigExtension\Line\FileLineStrategy());
$line->add(new Memio\TwigTemplateEngine\TwigExtension\Line\MethodPhpdocLineStrategy());
$line->add(new Memio\TwigTemplateEngine\TwigExtension\Line\ObjectLineStrategy());
$line->add(new Memio\TwigTemplateEngine\TwigExtension\Line\StructurePhpdocLineStrategy());

$twig->addExtension(new Memio\TwigTemplateEngine\TwigExtension\Type());
$twig->addExtension(new Memio\TwigTemplateEngine\TwigExtension\Whitespace($line));

$templateEngine = new Memio\TwigTemplateEngine\TwigTemplateEngine($twig);
$prettyPrinter = new Memio\PrettyPrinter\PrettyPrinter($templateEngine);

// Describe the code you want to generate using "Models"
$myService = (new File('src/Vendor/Project/MyService.php'))
        (new Objekt('Vendor\Project\MyService'))
            ->addProperty(new Property('createdAt'))
            ->addProperty(new Property('filename'))
                (new Method('__construct'))
                    ->addArgument(new Argument('DateTime', 'createdAt'))
                    ->addArgument(new Argument('string', 'filename'))

// Generate the code and display in the console
echo $prettyPrinter->generateCode($myService);

// Or display it in a browser
// echo '<pre>'.htmlspecialchars($prettyPrinter->generateCode($myService)).'</pre>';

With this simple example, we get the following output:


namespace Vendor\Project;

class MyService
    private $createdAt;
    private $filename;

    public function __construct(DateTime $createdAt, string $filename)

Have a look at the main respository to discover the full power of Memio.

Memio uses phpspec, which means the tests also provide the documentation. Not convinced? Then clone this repository and run the following commands:

composer install
./vendor/bin/phpspec run -n -f pretty
