### Eloquent YamlCast Example

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/README.md

Eloquent cast to automatically convert between YAML strings and arrays.

```php
use JeffersonGoncalves\FilamentYamlEditor\Casts\YamlCast;

class Setting extends Model
{
    protected $casts = [
        'config' => YamlCast::class,
    ];
}
```

--------------------------------

### YamlCast Eloquent cast

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Eloquent cast that stores YAML as text in the database and retrieves it as a PHP array. `get()` parses YAML string to array (returns `null` for null/empty); `set()` dumps array to YAML string using `Yaml::dump($value, 4, 2)` (returns `null` for null).

```php
use JeffersonGoncalves\FilamentYamlEditor\Casts\YamlCast;

class Server extends Model
{
    protected function casts(): array
    {
        return [
            'config' => YamlCast::class,
        ];
    }
}

// Usage
$server->config = ['key' => 'value'];  // Stored as YAML text
$server->config;                        // Returns array
```

```php
use JeffersonGoncalves\FilamentYamlEditor\Actions\ViewYamlAction;

// In a Filament table or page
ViewYamlAction::make()
    ->column('config')        // Required: the model attribute to display

```php
->recordActions([
    ViewYamlAction::make()
        ->column('config')       // required: the model attribute to display
        ->editorHeight(500)      // optional, default 400

--------------------------------

### YamlEditorEntry infolist entry

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Displays YAML content read-only in an infolist. Automatically handles array and string states; arrays are dumped to YAML using `Yaml::dump($state, 4, 2)`.

```php
use JeffersonGoncalves\FilamentYamlEditor\Infolists\Components\YamlEditorEntry;

YamlEditorEntry::make('config')
    ->height(300)    // Editor height in pixels (default: 300)
    ->dark()         // Force dark theme
    ->light()        // Force light theme
```

### Model with YAML Column

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Use YamlCast to cast a model attribute to YAML. The migration stores YAML as text in a 'steps' column.

```php
use JeffersonGoncalves\FilamentYamlEditor\Casts\YamlCast;

class Pipeline extends Model
{
    protected function casts(): array
    {
        return [
            'steps' => YamlCast::class,
        ];
    }
}

// Migration
Schema::create('pipelines', function (Blueprint $table) {
    $table->id();
    $table->text('steps');  // Store YAML as text
    $table->timestamps();
});
```

--------------------------------

### Basic Form Field Usage

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/README.md

Basic usage of the form field with toolbar and YAML validation.

```php
use JeffersonGoncalves\FilamentYamlEditor\Forms\Components\YamlEditorField;

YamlEditorField::make('config')
    ->withToolbar()
    ->rules(['yaml'])
```

--------------------------------

### Global yaml validator extension

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Uses the globally registered `yaml` validator extension in any validation context. The `yaml` rule is automatically replaced with the `ValidYaml` instance.

```php
// Works in any validation context
$request->validate([
    'config' => 'required|yaml',
]);
```

--------------------------------

### YAML Config Editor with Validation

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Use YamlEditorField in a Filament form to edit YAML with validation. The field is configured with a label, height, toolbar, state casting, auto-formatting, and validation rules.

```php
use JeffersonGoncalves\FilamentYamlEditor\Forms\Components\YamlEditorField;

public static function form(Form $form): Form
{
    return $form->schema([
        YamlEditorField::make('config')
            ->label('Server Configuration')
            ->height(500)
            ->withToolbar()
            ->castState()
            ->autoFormat()
            ->rules(['required', 'yaml'])
            ->columnSpanFull(),
    ]);
}
```

--------------------------------

### ValidYaml Rule Usage

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/README.md

Validation rule usage both as a rule object and as a string alias.

```php
use JeffersonGoncalves\FilamentYamlEditor\Rules\ValidYaml;

// As a rule object
$request->validate([
    'config' => ['required', new ValidYaml],
]);

// As a string alias (registered by the service provider)
$request->validate([
    'config' => ['required', 'yaml'],
]);
```

--------------------------------

### YamlEditorField form field configuration

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Configures a YAML editor form field with height, toolbar, state casting, auto-formatting, read-only mode, theme, and validation. The `rules(['yaml'])` automatically applies the `ValidYaml` rule. Default height is 300 pixels.

```php
use JeffersonGoncalves\FilamentYamlEditor\Forms\Components\YamlEditorField;

YamlEditorField::make('config')
    ->height(400)              // Editor height in pixels (default: 300)
    ->minLines(10)             // Minimum number of lines
    ->withToolbar()            // Enable toolbar (format, copy, expand)
    ->castState()              // Auto-convert between array and YAML string
    ->autoFormat()             // Auto-format YAML on load
    ->readOnly()               // Disable editing
    ->dark()                   // Force dark theme
    ->light()                  // Force light theme
    ->rules(['yaml'])          // Validate YAML syntax
    ->required()
```

--------------------------------

### Add custom validation after yaml rule

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Add custom validation rules after the 'yaml' rule to check the parsed structure when the ValidYaml rule only checks if Yaml::parse() succeeds.

```php
YamlEditorField::make('config')
    ->rules(['yaml'])
    ->afterStateUpdated(function ($state) {
        $parsed = Yaml::parse($state);
        // Validate structure...
    })
```

--------------------------------

### ValidYaml validation rule

Source: https://github.com/jeffersongoncalves/filament-yaml-editor/blob/3.x/resources/boost/skills/yaml-editor-development/SKILL.md

Validation rule that checks if a string contains valid YAML. Skips validation for non-string or blank values. Error messages include the YAML parse error details. Can be used standalone or automatically via the `'yaml'` string in `rules()`.

```php
use JeffersonGoncalves\FilamentYamlEditor\Rules\ValidYaml;

// Standalone usage
$request->validate([
    'config' => ['required', new ValidYaml],
]);

// In YamlEditorField (auto-applied)
YamlEditorField::make('config')
    ->rules(['yaml'])  // 'yaml' string is auto-replaced with ValidYaml instance
```
