Using the Generator

Introduction

The Generator class is the main entry point into swagger-php.

The \OpenApi\Generator class

The Generator class provides an object-oriented (and fluent) API to generate OpenApi specs and allows for easy customization where needed.

Full example of using the Generator class to generate OpenApi specs

require('vendor/autoload.php');

$validate = true;
$logger = new \Psr\Log\NullLogger();
$processors = [/* my processors */];
$finder = \Symfony\Component\Finder\Finder::create()->files()->name('*.php')->in(__DIR__);

$context = new OpenApi\Context();

$openapi = (new \OpenApi\Generator($logger))
            ->setProcessorPipeline(new \OpenApi\Pipeline($processors))
            ->setAliases(['MY' => 'My\Annotations'])
            ->setNamespaces(['My\\Annotations\\'])
            ->setAnalyser(new \OpenApi\Analysers\ReflectionAnalyser([new OpenApi\Analysers\DocBlockAnnotationFactory(), new OpenApi\Analysers\AttributeAnnotationFactory()]))
            ->setVersion(\OpenApi\Annotations\OpenApi::VERSION_3_0_0)
            ->generate(['/path1/to/project', $finder], new \OpenApi\Analysis([], $context), $validate);

Aliases and namespaces setting are optional and only required when using annotations. They allow to customize the parsing of docblocks and are passed through to the underlying doctrine/annotations library.

Defaults:

• aliases: ['oa' => 'OpenApi\\Annotations']

  Aliases help to parse annotations. Effectively, they avoid having to write use OpenApi\Annotations as OA; in your code and make [@OA](https://github.com/OA)\property(..) annotations still work.

• namespaces: ['OpenApi\\Annotations\\']

  Namespaces control which annotation namespaces can be autoloaded automatically. Under the hood this is handled by registering a custom loader with the doctrine annotation library.

Basic example

require('"vendor/autoload.php');

$openapi = (new \OpenApi\Generator())->generate(['/path1/to/project']);

The generate() method does not support the CLI exclude and pattern options directly. Instead, a custom Symfony Finder class (SourceFinder) can be used that understands these options.

$exclude = ['tests'];
$pattern = '*.php';

$openapi = (new \OpenApi\Generator())->generate(new \OpenApi\SourceFinder(__DIR__, $exclude, $pattern));
