WP Lemon Rector

A comprehensive Rector package with custom rules specifically designed for WP Lemon projects. This package includes Rector itself along with custom transformation rules for the Bulldozer block framework.

Installation

Install this package in your WP Lemon project using Composer:

composer require --dev studiolemon/wp-lemon-rector

This will install Rector along with all custom WP Lemon rules.

Usage

Since this package includes Rector, you can run it directly without any additional configuration:

# Using the WP Lemon Rector executable
vendor/bin/wp-lemon-rector process path/to/your/blocks --dry-run
vendor/bin/wp-lemon-rector process path/to/your/blocks

# Or using Rector directly
vendor/bin/rector process path/to/your/blocks --dry-run
vendor/bin/rector process path/to/your/blocks

Custom Configuration (Optional)

If you need to customize paths, add additional rules, or change settings, create a rector.php file in your project root:

<?php

declare(strict_types=1);

use Rector\Config\RectorConfig;

return RectorConfig::configure()
    ->withPaths([
        __DIR__ . '/web/app/themes/your-theme/blocks',
        __DIR__ . '/web/app/plugins/your-plugin/src',
    ])
    // Import the WP Lemon Rector configuration
    ->withSets([
        __DIR__ . '/vendor/studiolemon/wp-lemon-rector/rector.php',
    ]);

Custom Rules

This package includes custom Rector rules tailored for WP Lemon's Bulldozer block framework:

1. ClassesArrayToAddClassMethodRector

Transforms array assignments to the add_class() method:

// Before
$this->classes[] = 'section hero alignfull has-background';

// After
$this->add_class(['section', 'hero', 'alignfull', 'has-background']);

2. MergeConsecutiveAddClassCallsRector

Optimizes multiple consecutive add_class() calls by merging them into a single call:

// Before
$this->add_class(['bg-pill']);
$this->add_class(['section', 'has-background']);

// After
$this->add_class(['bg-pill', 'section', 'has-background']);

3. AttributesAlignToSetAlignmentRector

3. SiteIconsAttributesToConstructorRector

Transforms property assignments on a Site_Icons instance into a single constructor array argument:

// Before
$icons = new Site_Icons();
$icons->short_name = 'BusinessBase';
$icons->background_color = '#ffffff';
$icons->theme_color = '#f5f9e5';

// After
$icons = new Site_Icons([
    'short_name' => 'BusinessBase',
    'background_color' => '#ffffff',
    'theme_color' => '#f5f9e5',
]);

Transforms the align attribute assignment to the set_alignment() method:

// Before
$this->attributes['align'] = 'full';

// After
$this->set_alignment('full');

4. AttributesIdToSetAnchorRector

Transforms the id attribute assignment to the set_anchor() method:

// Before
$this->attributes['id'] = 'formulier';

// After
$this->set_anchor('formulier');

5. AttributesArrayToSetAttributeMethodRector

Fallback transformation for attribute assignments into set_attribute() when no more-specific rule applies:

// Before
$this->attributes['foo'] = 'bar';

// After
$this->set_attribute('foo', 'bar');

6. FieldsArrayToGetFieldMethodRector

Transforms field array access to the get_field() method:

// Before
$value = $this->fields['image_field'];

// After
$value = $this->get_field('image_field');

7. IsPreviewPropertyToMethodRector

Transforms is_preview property access to method call:

// Before
if ($this->is_preview) {
    // do something
}

// After
if ($this->is_preview()) {
    // do something
}

8. BlockDisabledPropertyToMethodRector

Transforms block_disabled property assignment to the set_disabled() method:

// Before
$this->block_disabled = true;

// After
$this->set_disabled();

9. InnerBlocksStringToMethodRector

Transforms InnerBlocks HTML string concatenation to the create_inner_blocks() method:

// Before
'InnerBlocks' => '<InnerBlocks allowedBlocks="' . esc_attr(wp_json_encode($allowed_blocks)) . '" template="' . esc_attr(wp_json_encode($template)) . '" />'

// After
'InnerBlocks' => self::create_inner_blocks($allowed_blocks, $template)
