# Worked extension examples

These developer-facing recipes are kept beside the package contract. Replace the example values with the site-specific records and data objects used by the calling workflow.

<!-- example: contract Capell\BlockLibrary\Contracts\BlockDefinitionProvider -->

```php
<?php
declare(strict_types=1);
final class ExampleBlockDefinitionProviderImplementation implements \Capell\BlockLibrary\Contracts\BlockDefinitionProvider
{
    /**
     * @return iterable<BlockDefinitionData>
     */
    public function definitions(): iterable
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\BlockLibrary\Contracts\BlockDefinitionProvider::class, ExampleBlockDefinitionProviderImplementation::class);
```

<!-- example: contract Capell\BlockLibrary\Contracts\BlockDemoContentProvider -->

```php
<?php
declare(strict_types=1);
final class ExampleBlockDemoContentProviderImplementation implements \Capell\BlockLibrary\Contracts\BlockDemoContentProvider
{
    /**
     * @return array<string, mixed>
     */
    public function demoContent(\Capell\BlockLibrary\Data\BlockDefinitionData $definition): array
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\BlockLibrary\Contracts\BlockDemoContentProvider::class, ExampleBlockDemoContentProviderImplementation::class);
```

<!-- example: contract Capell\BlockLibrary\Contracts\BlockFixtureProvider -->

```php
<?php
declare(strict_types=1);
final class ExampleBlockFixtureProviderImplementation implements \Capell\BlockLibrary\Contracts\BlockFixtureProvider
{
    /**
     * @return iterable<BlockFixtureData>
     */
    public function fixtures(\Capell\BlockLibrary\Data\BlockDefinitionData $definition): iterable
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\BlockLibrary\Contracts\BlockFixtureProvider::class, ExampleBlockFixtureProviderImplementation::class);
```

<!-- example: contract Capell\BlockLibrary\Contracts\BlockRenderer -->

```php
<?php
declare(strict_types=1);
final class ExampleBlockRendererImplementation implements \Capell\BlockLibrary\Contracts\BlockRenderer
{
    /**
     * @param  array<string, mixed>  $state
     */
    public function render(\Capell\BlockLibrary\Data\BlockDefinitionData $definition, array $state = []): \Illuminate\Contracts\Support\Htmlable|string
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\BlockLibrary\Contracts\BlockRenderer::class, ExampleBlockRendererImplementation::class);
```

<!-- example: contract Capell\BlockLibrary\Contracts\FilamentBuilderBlock -->

```php
<?php
declare(strict_types=1);
final class ExampleFilamentBuilderBlockImplementation implements \Capell\BlockLibrary\Contracts\FilamentBuilderBlock
{
    public static function getBuilderBlockName(): string
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
    public static function make(): \Filament\Forms\Components\Builder\Block
    {
        throw new LogicException('Implement this package contract for the calling site.');
    }
}

app()->bind(\Capell\BlockLibrary\Contracts\FilamentBuilderBlock::class, ExampleFilamentBuilderBlockImplementation::class);
```

<!-- example: action sanitizeBlockHtml -->

```php
<?php
declare(strict_types=1);
$inputs = []; // Supply the arguments required by the action handle() method.
resolve(\Capell\BlockLibrary\Actions\SanitizeBlockHtmlAction::class)->handle(...$inputs);
```
