classy

This project provides a composer package with a finder for classy constructs (classes, enums, interfaces, and traits).

Installation

Run

composer require ergebnis/classy

Usage

This package provides the following collectors for finding classy constructs:

• Ergebnis\Classy\Collector\TokenGetAllConstructFromSourceCollector
• Ergebnis\Classy\Collector\PhpTokenTokenizeConstructFromSourceCollector
• Ergebnis\Classy\Collector\DefaultConstructFromFileCollector
• Ergebnis\Classy\Collector\DefaultConstructFromSplFileInfoCollector
• Ergebnis\Classy\Collector\DefaultConstructFromFinderCollector

Collector\TokenGetAllConstructFromSourceCollector

Use Collector\TokenGetAllConstructFromSourceCollector to collect classy constructs from source code on PHP 7:

<?php

declare(strict_types=1);

use Ergebnis\Classy;

$source = Classy\Source::fromString(<<<'PHP'
<?php

namespace Example;

class Foo {}

enum Bar {}

interface Baz {}

trait Qux {}
PHP);

$collector = new Classy\Collector\TokenGetAllConstructFromSourceCollector();

$constructs = $collector->collectFromSource($source);

foreach ($constructs as $construct) {
    /** @var Classy\Construct $construct */
    echo sprintf(
        "- %s (%s)\n",
        $construct->name()->toString(),
        $construct->type()->toString(),
    );
}

// - Example\Foo (class)
// - Example\Bar (enum)
// - Example\Baz (interface)
// - Example\Qux (trait)

Collector\PhpTokenTokenizeConstructFromSourceCollector

Use Collector\PhpTokenTokenizeConstructFromSourceCollector to collect classy constructs from source code on PHP 8:

<?php

declare(strict_types=1);

use Ergebnis\Classy;

$source = Classy\Source::fromString(<<<'PHP'
<?php

namespace Example;

class Foo {}

enum Bar {}

interface Baz {}

trait Qux {}
PHP);

$collector = new Classy\Collector\PhpTokenTokenizeConstructFromSourceCollector();

$constructs = $collector->collectFromSource($source);

foreach ($constructs as $construct) {
    /** @var Classy\Construct $construct */
    echo sprintf(
        "- %s (%s)\n",
        $construct->name()->toString(),
        $construct->type()->toString(),
    );
}

// - Example\Foo (class)
// - Example\Bar (enum)
// - Example\Baz (interface)
// - Example\Qux (trait)

Collector\DefaultConstructFromFileCollector

Use Collector\DefaultConstructFromFileCollector to collect classy constructs from a file:

<?php

declare(strict_types=1);

use Ergebnis\Classy;

$filePath = Classy\FilePath::fromString(__DIR__ . '/example.php');

$collector = new Classy\Collector\DefaultConstructFromFilePathCollector(new Classy\Collector\TokenGetAllConstructFromSourceCollector());

$constructs = $collector->collectFromFilePath($filePath);

foreach ($constructs as $construct) {
    /** @var Classy\Construct $construct */
    echo sprintf(
        "- %s (%s)\n",
        $construct->name()->toString(),
        $construct->type()->toString(),
    );
}

// - Example\Foo (class)
// - Example\Bar (enum)
// - Example\Baz (interface)
// - Example\Qux (trait)

Collector\DefaultConstructFromSplFileInfoCollector

Use Collector\DefaultConstructFromSplFileInfoCollector to collect classy constructs from an instance of SplFileInfo:

<?php

declare(strict_types=1);

use Ergebnis\Classy;

$splFileInfo = new \SplFileInfo(__DIR__ . '/example.php');

$collector = new Classy\Collector\DefaultConstructFromSplFileInfoCollector(new Classy\Collector\TokenGetAllConstructFromSourceCollector());

$constructs = $collector->collectFromSplFileInfo($splFileInfo);

foreach ($constructs as $construct) {
    /** @var Classy\Construct $construct */
    echo sprintf(
        "- %s (%s)\n",
        $construct->name()->toString(),
        $construct->type()->toString(),
    );
}

// - Example\Foo (class)
// - Example\Bar (enum)
// - Example\Baz (interface)
// - Example\Qux (trait)

Collector\DefaultConstructFromFinderCollector

Use Collector\DefaultConstructFromFinderCollector to collect classy constructs from an iterable of SplFileInfo:

<?php

declare(strict_types=1);

use Ergebnis\Classy;
use Symfony\Component\Finder;

$finder = Finder\Finder::create()
  ->files()
  ->in(__DIR__ . '/src');

$collector = new Classy\Collector\DefaultConstructFromFinderCollector(new Classy\Collector\TokenGetAllConstructFromSourceCollector()));

$constructs = $collector->collectFromFinder($finder);

foreach ($constructs as $construct) {
    /** @var Classy\Construct $construct */
    echo sprintf(
        "- %s (%s)\n",
        $construct->name()->toString(),
        $construct->type()->toString(),
    );
}

// - Example\Foo (class)
// - Example\Bar (enum)
// - Example\Baz (interface)
// - Example\Qux (trait)
